* " lock " Interlocking of points and signals, so that conflicting signal indications are prevented ;

Interlocking was attached to the levers, which ensured that signals showed the correct indication with regard to the points and were operated in the right order.

Proper interlocking of the signals and point work did not exist until 1981, and the station was not fully interlocked until 1998 when a Solid State Interlocking was provided.

" Interlocking " or " home " signals have a double head and show two colored lights.

Interlocking signals can also take part in grade timing, with aspects such as yellow over green over white ( meaning the same as yellow over white ).

* Interlocking roof tiles are similar to pantile with side and top locking to improve protection from water and wind.

The station is located on the exclusive LRT right of way ( adjacent to CPR ROW ) at 61 Avenue SW, 5. 7 km South of the City Hall Interlocking.

It is located on the exclusive LRT right of way, 1. 7 km South of the City Hall Interlocking, beside Macleod Trail at 25 Avenue SE.

The station is located on the exclusive LRT right of way 3. 4 km South of the City Hall Interlocking, at 39 Avenue SE, just East of Macleod Trail and serves the Alyth-Manchester industrial area as well as the Elboya neighbourhood.

The station is located on the exclusive LRT right of way ( adjacent to CPR ROW ), 9. 5 km South of the City Hall Interlocking at Southland Drive.

The tracks join the Northeast Corridor at Zoo Interlocking near the Philadelphia Zoo and 30th Street Station.

The nearby Thornton Friends School, named after former Sandy Spring Friends Head of School C. Thornton Brown, traces its roots to an innovative academic program, the “ Interlocking Curriculum ,” that was first developed at SSFS in 1973.

Interlocking is used to make sure that the signal cannot be set to allow passage onto the main line until the trap points have been aligned to ensure this movement can take place.

Rather than the traditional format established by Dungeons & Dragons, which often involved the characters wandering randomly through caves or tunnels and fighting different types of monsters, Sandy Petersen introduced the concept of the Onion Skin: Interlocking layers of information and nested clues that lead the Player Characters from seemingly minor investigations into a missing person to discovering mind-numbingly awful, global conspiracies to destroy the world.

" Interlocking " or alternating rhythm features in Eastern African xylophone music such as that of the Makonde dimbila, the Yao mangolongondo or the Shirima mangwilo in which the opachera, the initial caller, is responded to by another player, the wakulela.

The exhibition, entitled 33 MacDougal Alley: The Interlocking Sculpture of Isamu Noguchi, featured eleven of the artist ’ s interlocking sculptures.

The system uses an IPU ( Interlocking processing unit ), TI21-M track circuits and EbiScreen workstations.

" Building a rolltop desk: Interlocking slats form an all-wood tambour.

Interlocking mat is commonly used on a one-time or temporary basis: fitness centres and sport competitions, trade shows and conferences.

Also in 2003, Staten Island replaced their batting practice jersey which originally features the Yankees script logo across the chest with one that featured the Interlocking SI logo.

The new Solid State Interlocking was commissioned in 1989, and was the first fully computerised system in Melbourne.

The 20-to-1 ratio for cochannel interference embodies one of the fundamental limiting principles which we must always take into account in AM assignments and allocations -- that signals from a particular station are potential sources of objectionable interference over an area much greater than that within which they provide useful service.

But during nighttime hours the skywave radiations are reflected from the ionosphere, thereby creating the possibility of one station's rendering service, via skywave, at a much greater distance than it can through its groundwave signal, and at the same time vastly complicating the interference problem because of the still greater distance over which these skywave signals may cause interference to the signals of stations on the same and closely adjacent frequencies.

It was recognized that skywave signals, because of their reflected nature, are of great variability and subject to wide fluctuations in strength.

The linguistic and paralinguistic signals of misery are all present in the voice chart for this sentence ; ;

so are certain signals that she does not accept divorce.

The clocks are compared using GPS signals and Two-Way Satellite Time and Frequency Transfer.

Axons are distinguished from dendrites by several features, including shape ( dendrites often taper while axons usually maintain a constant radius ), length ( dendrites are restricted to a small region around the cell body while axons can be much longer ), and function ( dendrites usually receive signals while axons usually transmit them ).

Compared to digital signals, analog signals are of higher density.

Changes in pottery composition, structure and decoration are signals of social change in the archaeological record.

In a common technique of acoustic measurement, acoustic signals are sampled in time, and then presented in more meaningful forms such as octave bands or time frequency plots.

Video cards are designed for inputting and outputting video signals, and processing and manipulating video.

Audio signals are sound waves — longitudinal waves which travel through air, consisting of compressions and rarefactions.

These audio signals are measured in bels or in decibels.

* echo-to simulate the effect of reverberation in a large hall or cavern, one or several delayed signals are added to the original signal.

When large numbers of delayed signals are mixed over several seconds, the resulting sound has the effect of being presented in a large room, and it is more commonly called reverberation or reverb for short.

* phaser-another way of creating an unusual sound ; the signal is split, a portion is filtered with an all-pass filter to produce a phase-shift, and then the unfiltered and filtered signals are mixed.

The monochrome combinations still existing in the 1950s are standardized by the International Telecommunication Union ( ITU ) as capital letters A through N. When color television was introduced, the hue and saturation information was added to the monochrome signals in a way that black & white televisions ignore.

Most AC-III's are integral membrane proteins involved in transducing extracellular signals into intracellular responses.

This is supported by the fact that adenylate cyclases are coincidence detectors, meaning that they are activated only by several different signals occurring together.

Birds are social ; they communicate using visual signals and through calls and songs, and participate in social behaviours, including cooperative breeding and hunting, flocking, and mobbing of predators.
