Abstract: 1,178,048. Gas turbine engine fuel systems. H. M. HOBSON Ltd. May 24, 1968 [July 5, 1967], No.30985/67. Heading F1G. [Also in Division G3] A fluidic temperature sensing apparatus comprises an oscillator 1 motivated by hot air producing a train of pressure pulses at a frequency representative of the temperature to be sensed, a variable frequency oscillator 6 producing a second train of pressure pulses, a fluidic amplifier 11 controlled by the two trains of pressure pulses to cause a pressure differential across an actuator 13, and means 7 controlled by the actuator for adjusting the oscillator 6 to bring its frequency into harmony with that of the oscillator 1. The frequency generated by the oscillator 1 is dependent on the velocity of air at the inlet and the velocity is in turn dependent on temperature. A flip-flop oscillator 2 supplied with cooler air has its control ports connected to the outlets of the oscillator 1 and one of its own outlets connected through a direct line 3 and a delay line 4 to the control ports of a pulse width modulator 5. Pulses of reduced width, corresponding to the difference in transit time through the lines 3 and 4, are produced by the modulator 5 and applied to one control port of a flip-flop 11 having its other control port connected through a similar modulator 8 to the oscillator 6. An output proportional to the difference between the frequencies of the two trains of pulses is established in one of the outlets of the flip-flop 11 and after amplification in a stage 12 displaces a piston 13 and the effective length of a reed 7 until a null is reached. The piston 13 can be utilized to actuate a temperature indicator or a needle or bleed valve controlling the fuel flow to a gas turbine. The apparatus may receive motive fluid from the compressor of the turbine.

Filed: 1969-06-23
Abstract: 1,247,971. Multiplex pulse code signalling. MARCONI CO. Ltd. 5 Feb., 1970 [23 June, 1969], No. 31489/69. Heading H4L. In a multiplex digital data transmission system where a buffer store for each channel receives input data at a lower rate than the read-out by the transmitter clock, the stuffing pulses inserted at intervals are in groups of bits identifying the particular channels. As shown applied to a four-channel multiplexer each channel such as 1 supplies serial data which is entered in a four-stage register 66 under control of the input data clock 11 and distributer 16 and read out by a similar distributer 21 at transmitter clock (69) rate. Comparator 25 detects change of phase of the clocks and when this reaches the point where the register is not yet loaded it inhibits distributer 21 over line 26 and orders over 27 the insertion by encoder 28 of a four-bit channel-identifying code to the line 24 to the multiplexer. The receiver (Fig. 2, not shown) is provided in each de-multiplexed channel with a code detector which orders the deletion of the identifying codes from the channel buffer and also controls the buffer read clock rate in accordance with the frequency of receipt of the coded stuffing signals. The de-multiplexer may be of the type described in Specification 1,246,879 which utilizes the coded stuffing signals to control synchronization. It is stated that in order to prevent the recognition of fortuitous channel-identifying groups in the message proper, the code detectors may be each arranged to be operative only when a stuffing signal is to be expected, this expectation being based on the current rate of stuffing.

Title: Submersible device for advertisement purposes and toys
IPC: A63H23/04
Filed: 1929-10-18
Abstract: 338,681. Herbst, P. Oct. 18, 1929. Diving toys. - A toy of the kind adapted alternately to submerge and emerge under the action of air escaping slowly from a container, is provided with a valve b, Fig. 1, regulating the flow of air through an outlet h and comprising apertured metal discs d, separated by felt packing members c and pressed together by an adjusting screw a. In operation the toy is normally submerged, but rises periodically upon the formation of a bubble around the outlet h in the screw a. Upon reaching the surface, the bubble bursts and the toy sinks. In larger toys, the outlet h exhausts into a collecting chamber e, the air gradually forcing the water out of the chamber through an aperture k until the toy rises. Upon reaching the surface the air is exhausted from the chamber through a port i that may or may not be fitted with a float valve f. In order to prevent too rapid escape of air when the air container is first filled, a pressure-reducing valve g may be interposed between the container and the valve b. This valve comprises a spindle z normally held in open position, by a spring x but adapted to be closed by the pressure of air below a diaphragm y, with the result that the valve periodically opens and closes to admit air into the space below the diaphragm. The toy may be used as an advertising device.

Abstract: 810,065. Magnetic machines. PROTONA PRODUKTIONSGESELLSCHAFT FUER ELEKTROAKUSTISCHE GERAETE G.m.b.H. Oct. 19, 1956 [Oct. 24, 1955], No. 31812/56. Class 40 (2). A drive mechanism for miniature magnetic recorders comprises a drum 24 driven always in the same direction by an electric motor and a belt 27. The drum bearings are supported in brackets 22 and 23 mounted on slide bar 15, normally held to the left by spring 37, so that the small diameter 29 is in frictional contact with the edge of the take-up spool support 5-see Fig. 2, which shows the apparatus in the recording condition. Rapid rewind is engaged by depressing key 39 which moves slide bar 15 to the right so that face 28 is in frictional contact with the edge of the feed spool 13. Also carried on the slide bar 15 are two running brakes 30 and 31, to keep the wire taut, the brake 30 applying a drag to spindle 2 during rewind and brake 31 applying a drag to spindle 3 during forward feed. A second slide bar 16 normally held to the right by spring 51 carries two stopping brakes 53 and 54 applied by depressing key 38 which also switches off the motor. The drum 24 is not rigidly attached to its spindle 25 but has longitudinal freedom of movement, spring 63 (Fig. 5) being interposed between the drum 24 and fixed pin 64, so that when changing from rapid rewind to slow forward drive the brake 30 remains in engagement with spindle 2 until after the face 29 is in contact with support 5. The period of this braking is determined by the speed at which slide bar 15 moves to the left, this being controlled by the retarding mechanism 37a. The amount of wire on each spool is shown by a spiral line 71 on the roller 70 co-operating with a fixed datum line 72. Roller 70 is driven from the take-up spool by flexible shaft 76 and gearing 73, 74, 75, 77 and 78.
