In the 1870s Duncan MacKinnon, a Canadian living in New York City, and Alonzo T. Cross of Providence, Rhode Island, created stylographic pens with a hollow, tubular nib and a wire acting as a valve.

The Model T four-cylinder side valve engine was first in the world with a detachable head, making service like valve jobs easier.

The location of best auscultation for each heart valve are labeled with " M ", " T ", " A ", and " P ". First heart sound: caused by atrioventricular valves-Bicuspid valve | Mitral ( M ) and Tricuspid valve | Tricuspid ( T ).

It includes the handling package, a chrome valve cover, three-piece spoiler, T / A steering wheel, and special body decals.

* William T. James valve gear 1832, used first by Baltimore and Ohio Railroad, USA.

It is easy to see that a T valve can connect any pair of ports, or all three, together, but the 45 degree position which might disconnect all three leaves no margin for error.

However, a valve in the propellant line failed to close at T − 90 seconds, causing a large fire to start at the base of the launch vehicle only one minute before launch.

The " Formula " option was also introduced for the Astre's final year, which included the handling package, chrome valve cover, three-piece spoiler, Formula T / A steering wheel and special decals.

A Williamson amplifier refers to a type of vacuum tube ( valve ) amplifier whose circuit design uses the same principles as a design published by D. T. N.

Examples with the VNT system intact are today considered more valuable to collectors. Time has proven them to be quite reliable, unlike the later 16 valve as used in the Spirit R / T.

* All T engines utilize a timing chain and have a cast iron block with an alloy cylinder head with hardened valve seats and a hemispherical combustion chamber design ( HEMI )..

* All T engines use a 2 valve OHV design except those with a DOHC performance head, " G " designation.

L & T Valves Business Group has offices in the USA, South Africa, Dubai, Abu Dhabi, India and China, and strategic alliances with leading integrated valve distributors and agents in the major markets.

The view that there was no rigid structure is reinforced by S. T. Joshi, who stated " Lovecraft's imaginary cosmogony was never a static system but rather a sort of aesthetic construct that remained ever adaptable to its creator's developing personality and altering interests ... here was never a rigid system that might be posthumously appropriated ... he essence of the mythos lies not in a pantheon of imaginary deities nor in a cobwebby collection of forgotten tomes, but rather in a certain convincing cosmic attitude.

In this case, we might compute T = A *( B * D ) only once and simply blend T * C to produce F, a single operation.

T. S. Eliot said: " It is difficult for us to read that essay without reflecting that if Poe plotted out his poem with such calculation, he might have taken a little more pains over it: the result hardly does credit to the method.

Still, one might expect that since T is a partial function from the natural numbers onto the real numbers, that therefore the real numbers are no more than countable.

Therefore primer sequence corresponding to the amino acid isoleucine might be " ATH ", where A stands for adenine, T for thymine, and H for adenine, thymine, or cytosine, according to the genetic code for each codon, using the IUPAC symbols for degenerate bases.

So, for example, the T form might be used when speaking to a friend or social equal, whereas the V form would be used speaking to a stranger or social superior.

Cheung Chuk Ling, W. T. Pearce, and H. R. Wells revived the college so that the training of the sons of church members might be carried on.

First, low-level autoimmunity might aid in the recognition of neoplastic cells by CD8 + T cells, and thus reduce the incidence of cancer.

It might be tempting to suppose a matrix with orthogonal ( not orthonormal ) columns would be called an orthogonal matrix, but such matrices have no special interest and no special name ; they only satisfy M < sup > T </ sup > M = D, with D a diagonal matrix.

It might be noteworthy that even though DB assigned the name ICE-T to class 411 / 415, the T originally did not stand for tilting but for Triebwagen ( self-propelled car ), as DB's marketing department at first deemed the top speed too low for assignment of the InterCityExpress brand and therefore planned to refer to this class as IC-T ( InterCity-Triebwagen ).

The motion of a charged body in a magnetic field, B involves the velocity through the Lorentz force term v × B, and might seem at first to be asymmetric under T. A closer look assures us that B also changes sign under time reversal.

For example, for a situation where the human impact on climate change is being measured, an appropriate unit for T might be greenhouse gas emissions per unit of GDP.

Before starting a Model T with the hand crank, the spark had to be manually retarded or the engine might " kick back ".

Livy states that Hannibal deployed 4000 Macedonians in the second line, which is normally rejected as Roman propaganda, though T Dorey suggested that there might have been a seed of truth in the story if the Carthaginians had recruited a trivial number of mercenaries from Macedonia who had gone without official blessing.

We might note that if T is multiplication by f, then the spectrum of T is just the essential range of f.

According to Merck the standard drug to counter infection is pyrimethamine, but most immunocompetent asymptomatic people infected with T. gondii, with the exception of neonates and pregnant women, require no treatment though recent studies have indicated an influence of T. gondii on suicidal behaviours in humans which — if widely confirmed — might warrant treatment attention.

" Golden Owl " might also refer to the related Golden Masked Owl ( T. aurantia ).

Thus, the tangent bundle TM = T ( M ) might sometimes be written as

Although T ' Pol subsequently overcame her addiction, Phlox determined that she had permanently damaged her brain, and as a result might never achieve the same level of emotional control she once had.

In terms of chemical potentials there are now three equations, which cannot in general be satisfied by any values of the two variables T and p, although in principle they might be solved in a special case where one equation is mathematically dependent on the other two.

From the palaeographical evidence, T. Julian Brown concluded that the Cuthbert manuscript was written after the main text of the Codex Amiatinus, which was finished after 688, perhaps by 695, though it might be later.

Second, even if the characteristic polynomial factors completely over F into a product of polynomials of degree 1, there may not be enough characteristic vectors for T to span the space V.

Let T be a linear operator on the finite-dimensional vector space V over the field F.

Let p be the minimal polynomial for T, Af, where the Af, are distinct irreducible monic polynomials over F and the Af are positive integers.

Let T be a linear operator on the finite-dimensional vector space V over the field F.

Then every linear operator T in V can be written as the sum of a diagonalizable operator D and a nilpotent operator N which commute.

In the primary decomposition theorem, it is not necessary that the vector space V be finite dimensional, nor is it necessary for parts ( A ) and ( B ) that P be the minimal polynomial for T.

As S approaches T the square will be outside C and therefore both Af and Af must cross C an odd number of times as S varies from zero to T.

First, for any value of T for which all values of f{t} are ordinary points the number of values of f{t} must be odd.

For it is clear that the total number of ordinary intersections of C and Af must be even ( otherwise, starting in the interior of C, Af could not finally return to the interior ), and the center of rotation at T is the argument of the function, not a value.

The number of ordinary values of the function f{t} at T will be called its multiplicity at T.

Now Af and Af must both be tangent points on the T component in the f-plane ; ;

Thus the multiplicity of Af for a given T must be an even number.

As S varies from zero to T, the values of S for which Af and Af cross C will be denoted by Af and Af respectively.

Clearly, any line, l, of any bundle having one of these points of tangency, T, as vertex will be transformed into the entire pencil having the image of the second intersection of L and Q as vertex and lying in the plane determined by the image point and the generator of Af which is tangent to **zg at T.

From Fig. 6 the relationship between these parameters can readily be derived and the cutting force is Af where **yl is the shear strength of the coating and is a parameter of the coatings material, W is the width of the removed coating and T is its thickness.

These will be numbered in the direction opposite to the flow of the process stream, so that stage R is the T stage from the end.

If T is the total `` length '' of the process, its feed state may be denoted by a vector p(T) and the product state by p(Q).

But Henry Ford used the planetary transmission in his Model T and earlier cars and, in 1905, as a precautionary measure, took out a license from the man who claimed to be its inventor.

Errors in publication may be corrected by issuing a revision of the faulty Circular T or by errata in a subsequent Circular T. Aside from this, once published in Circular T the TAI scale is not revised.
