Patent GB-2031089-A (GB)
Title: Valve and connector device
IPC: F16K21/04
Filed: 1978-09-20
Abstract: A valve and connector device for temporarily connecting a branch tyre inflator air supply pipeline 80 into the main brake air supply pipeline of the compressed air supply system of a motor vehicle having air operated brakes comprises a valve unit 10 and branch pipeline terminal connector element 12. Sliding valve member 38 controls communication between inlets 24, 26, from the air supply, and outlet 28 to the brakes and outlet 40 for the branch pipeline. When branch pipeline 80 is disconnected valve member 38 closes communication to outlet 40 and compressed air flows to outlet 28. When branch pipeline 80 is connected connector element 12 plugs into outlet 40, engages and interlocks with valve actuating element 64, and moves valve member 38 to close communication to outlet 40 and divert the air supply to pipeline 80. Interlocking hook projections 68 and 88 ensure that connector element 12 and valve actuating element 12 cannot be disengaged to disconnect pipeline 80 until valve member 38 is reset to its original position by withdrawing element 12. <IMAGE>

Title: Bistable relay control arrangement
IPC: H01H47/22
Filed: 1978-10-23
Abstract: A bistable relay (R1s) is switched to its de-activated state when an excitation voltage (U) is removed. The series circuit of the relay coil and a capacitor (C1) is connected to the excitation voltage (U) for energising the relay and charging the capacitor (C1) and is short circuited, upon absence of the excitation voltage (U1), through a semiconductor switch (T1). After the capacitor has been fully charged and the excitation voltage switched off, a voltage drop appears across a resistance element (D1) which renders the semiconductor switch conductive whereby the series circuit is short-circuited and the relay switches back to its original de-energised state. In other arrangements, the control switch(s) and/or the switch (T1) are replaced by a bistable switch such as a cross-coupled pair of transistors, or SCRs. These, together with zener diodes precisely determine the voltages at which the relay becomes energised and de-energised. <IMAGE>

Title: Telephone answering machines
IPC: H04M1/652
Filed: 1979-04-04
Abstract: A telephone answering machine which is remotely controlled by a predetermined audio frequency control signal transmitted via a telephone line and in which an audio signal detector at the input to the machine receives incoming low amplitude control signals and outgoing high amplitude audio signals reproduced by the machine when operating in the playback mode includes an automatic gain controlled amplifier, a filter and a threshold detector arranged so that in the presence of an outgoing audio signal, an incoming control signal is only amplified sufficiently to be detected and actuate the control unit when there is a break in the audio signal. To distinguish between a genuine incoming control signal and a spurious signal reproduced by the machine, the control unit checks whether the control signal ceases when reproduction ceases, as in the case of a spurious signal, or continues, as in the case of a genuine signal.

Title: Detection of spurious high temperature sources in the field of view of a pyrometer
IPC: G01J5/60
Filed: 1979-07-09
Abstract: A pyrometer system for the measurement of the temperature of a primary source of heat e.g. at turbine blade 52 which might be contaminated by radiation from a transient spurious source of heat at a higher temperature e.g. a hot particle 53, and in which the presence of radiation from the spurious source can be detected or identified by spectral discrimination. The received radiation is separated at 57 into two spectral components of which a second component comprises a significantly higher proportion of radiation emitted by the spurious source than does the first component. The difference between the magnitudes of the radiation in the second and first components is found at 58-78 and used to identify or detect the presence of spurious radiation and to produce an error, or flag, signal which is used at 88 to inhibit operation of the pyrometer or to cause it to hold the last received "good" reading before the occurrence of the spurious radiation; the error signal may also be used to compensate the first component for the effects of the spurious source, Fig. 3 (not shown). <IMAGE>

Title: Fluidized bed incinerator
IPC: F23G5/30
Filed: 1979-08-31
Abstract: There is provided a method and an apparatus for the operation of a fluidized-bed incinerator wherein a portion of the fluidized-bed medium (2) of the furnace is caused to pass a heat exchanger (8) during tapping from the combustion chamber of the furnace, and after cooling in the heat exchanger (8) is returned to the fluidized bed in the combustion chamber. The cooled fluidized-bed medium may be returned directly to the fluidized bed in the combustion chamber or it may be returned to the combustion chamber in an upper portion thereof and be allowed to fall through a distributor (13) so that it cools the zone above the fluidized bed at the same time as the medium is heated by waste gases from the combustion. The tapping of fluidized- bed medium is preferably controlled by a thermostat sensing the temperature of the fluidized bed. In an alternative arrangement the heat exchanger may be within a lower part of the fluidized bed. <IMAGE>
