Abstract: 674,010. Valves. RONCERAY, R. A. M. Nov. 9, 1949 [Jan. 28, 1949], No. 28756/49. Class 135. Apparatus for controlling rotary valves of the type described in Specification 652,070 comprises a pressure-fluid operated piston actuating a rack engaging a pinion for rotating a free-wheel device secured to the valve shaft, and means for returning the piston to its initial position after each operation. As shown, a manually-actuated, spring-loaded valve allows pressure fluid through a pipe 9, Fig. 2, to move a piston 11 downward so that the rack 13 on the piston rod turns a pinion 14 which, through a free-wheel device comprising spring- loaded lifters 16a on a hub 16 entering notches 14a in the pinion, turns the shaft 15 keyed to the hub. For a complete downward movement of the piston, limited by a stop 23, the shaft turns a rotary valve 18, Fig. 3, through a pin and slot connection 17 so that a port 24 moves from one fluid distribution port 21 to the next, the piston then being returned by fluid under pressure in the annular space 12 or by a spring in readiness for the next movement of the port 24.

[Also in Groups XXIX and XXXVII] Ice formation in duct 15 of an aircraft jet engine is prevented by providing one or more pitot members 35 which each normally produces a takeoff pressure different from the ambient pressure to keep open an electric switch; when ice closes one of the pilot openings the switch closes and opens solenoid-operated valves 24 and 24a which supply hot air from the engine to heat-exchangers H, H2 supplying heated air to a header D in the jet inlet and to the members 35 respectively. If ice-formation persists a valve 24b may be operated manually to bring heat exchanger H3 into operation. The electrical operation of valves 24 and 24a is conditional on the closure of a switch 68 actuated by a negative-pressure device 72 so that the heaters are only operated when airflow in the duct reaches a certain value. Specification 771,153 is referred to.

Title: Binary coding circuits for electric pulse code modulation systems of communication
IPC: H04B14/04
Filed: 1948-11-05
Abstract: 661,020. Multiplex pulse code signalling. STANDARD TELEPHONES & CABLES, Ltd. Nov. 5, 1948 [Nov. 8, 1947], No. 28818/48. Class 40 (v). A binary coding circuit for a pulse code modulation communication system comprises a plurality of similar coding units arranged in cascade, each of which has means transmitting to the next unit a pulse derived by delaying and doubling the amplitude of the input pulse in the case when the amplitude does not exceed half a specified value, or, alternatively, with the amplitude in excess of the half-value doubled, an output code pulse being generated in response to one of the cases. In the embodiment described, at the transmitter a distributer 1, Fig. 3, has a plurality of channel signal inputs 2 and produces synchronizing pulses in lead 3 and amplitude modulated signal pulses in lead 4. The signal pulses are fed to the chain of circuits 5, 6, 7, 8, 17. Each of circuits 5 ... 8 comprises a delay line 9 producing a delay equal to the desired time interval between two code pulses, followed by a voltage doubling amplifier 12 feeding the output terminal 16. If the amplitude of the input pulse is less than 0.5 of the maximum signal level the pulse passes to the terminal 16 after delay in circuit 9 and doubling in amplifier 12. If it is greater than 0.5 times the maximum signal level, it is passed by the threshold amplifier 10, the excess amplitude doubled thereby and the resulting pulse sent to the output terminal 16 through a delay circuit 13 similar to circuit 9. At the same time the output pulse from amplifier 10 is sent over lead 15 to mixer 14, after limitation in circuit 11, to form one of the code pulses in output lead 18. Another output from circuit 11 disables the voltage-doubling amplifier 12 for a time sufficient to prevent the passage of the corresponding pulse from delay circuit 9. The output from circuit 8 is fed to the fifth code pulse circuit 17 which is a threshold device passing the pulse only if it exceeds 0.5 times the maximum signal level. The Specification as open to inspection under Sect. 91 comprises also a decoding circuit in which the synchronizing and code pulses are fed to a distributer 19, Fig. 4 (Cancelled), and the code pulses belonging to the same group are distributed to the leads 21 ... 25 respectively. The delay circuits 26... 29 respectively, cause the first four pulses to arrive at the common output lead 46 simultaneously with the fifth pulse from lead 25. The amplitudes of the pulses are individually fixed by valves 34... 38 respectively, the currents flowing when pulses are applied to their grids being suitably weighted by the individual cathode resistances 39 ... 43. The amplitude of the combined pulse is thus proportional to the amplitude of the pulse used to determine the code at the transmitter. This subjectmatter does not appear in the Specification as accepted.

Abstract: 668,658. Pneumatic transmission of power. TRICO PRODUCTS CORPORATION. Nov. 14, 1949 [Nov. 20, 1948], No. 29116/49. Class 8 (ii) An accessory system for a motor vehicle housing two pneumatic accessory units e.g., a defroster nozzle 10 and a windscreen wiper 12 comprises a motor 2 housing a driven shaft 26 provided with two sets of air impelling means e.g. a blower 1 and a rotary suction pump 24, one for each accessory, and controls e.g. a switch 6 and a cable 19 individual to each unit for energizing the motor 2. An alternative source of suction for a motor 14 driving the windscreen wiper 12 is the inlet manifold 16 of the vehicle engine. and when this suction reaches a predetermined value it breaks a switch 21 to stop the motor 2. The control 19 is mechanical and actuates both the switch 21 which is in parallel with switch 6 and a valve 18 of the suction motor 14. In a modification one end of the driven shaft drives an impeller delivering through a heater to the vehicle interior, and the other end of the shaft drives a compressor which delivers to that side of the pneumatic motor remote from the side supplied with suction from the manifold. The compressor may thus co-operate with the suction manifold to drive the pneumatic motor. Specification 644,209, [Group XXIII], is referred to.

The performance of the electron beam parametric amplifier of the parent Specification is improved, by delaying to higher frequencies and modulation levels the onset of saturation and non-linear effects due to the deceleration of the electron beam, by surrounding the drift path with a plurality of coaxial, axially spaced hollow cylindrical electrodes of non-magnetic material, the odd numbered members of which are so disposed that their centre planes contain the successive points at which the beam electrons cross the beam axis in the magnetostatic pumping field. The odd numbered members are held at a lower D.C. potential than the even members, such that a periodic electrostatic field is produced which is arranged to axially accelerate the beam electrons by an amount which increases with displacement from the beam axis, to maintain constant the transit time between two intersections with that axis.
