Patent GB-2053621-A (GB)
Title: Digital Communication Bus System
IPC: H04Q11/04
Filed: 1980-06-16
Abstract: A digital bus system for the transmission of pulse code modulated speech and control data between a common multiplexer and a multiplicity of line circuits in a telecommunications system. In the past the line circuits were multiplexed directly onto a common bus so that failure of one line circuit could result in the balance of the line circuits on that bus being rendered unserviceable. In the present system each line circuit is coupled over a separate data line to a pair of multiplexers so that failure of any one line circuit does not affect the operation of the others. Under normal operation one of the multiplexers functions as the primary and the other as a secondary. However, should the primary multiplexer fail, the secondary will take over upon actuation of a single control signal from a controller.

Title: Balanced armature transducers
IPC: H04R11/00
Filed: 1980-10-02
Abstract: An electro-acoustic transducer of the balanced armature type, for use as a telephone earpiece or microphone, has its magnetic circuit formed by two parallel magnetic material yokes (1, 2), between which is located a speech coil (9). A ceramic permanent magnet (5) is located between the ends of the yoke at one end of the transducer. At the other end the yokes are angled inwards (4) to define a short narrow gap in which a flat reed-like armature (10) of ferro-magnetic material is secured. This is held in place with spacers (11) of a weakly magnetic material e.g. nickel, to facilitate welding. The armature extends through the speech coil (9) and into another narrow gap defined by inward-angled portions of the yokes. This, the main gap, is of relatively large area. Between the main gap and the speech coil a drive rod (7) is secured, preferably not by welding to avoid distorting the armature, and this drive rod drives a conical diaphragm. <IMAGE>

Title: Incinerator/Heater
IPC: F24B1/02
Filed: 1981-04-02
Abstract: The invention relates to an incinerator/heater providing substantially a chamber 7 within which combustible products may be burned in air and passing a stream of air over the surface heated by the combustion and transferring the thus heated air to the space required to be heated.
