IPC: G11C27/00

Abstract: 1,265,697. Frequency memory. INTERNATIONAL BUSINESS MACHINES CORP. 22 July, 1969 [1 Aug., 1968], No. 36771/69. Heading H3T. A frequency memory has means, such as Gunn effect circuit 30, amplifying, limiting and expanding a received radio frequency wave and a closed regenerative loop 71 including a delay means 68 coupling the output to the input of the means 30. The Gunn effect circuit acts as an expander since there is a low gain output until the input power exceeds a threshold (PT, Figs. 5B, 5C, not shown), where higher gain is provided. Above this threshold the Gunn effect device acts as a limiter, the high gain being reduced with increasing input power. The closed loop 71 includes an adjustable delay or phase shifter 68. The circuit operates as a frequency memory by reading in an input RF 31 modulated at 36 to produce rectangular inputs to a Gunn effect circuit 30 via a read in coupler 44 and circulator 48. The modulator pulse generator 38 also times the bias to the Gunn effect circuit 30 to be applied below the threshold for oscillations when the input is read in. Then provided the input frequency is within a range and the oscillation threshold is exceeded the Gunn effect circuit 30 is triggered into oscillation at that frequency and continues to oscillate due to the loop 71 to store that frequency until quenched by lowering the bias voltage or by a transmission device which modulates the loop loss. The frequency mode at which the oscillations occur can be tuned by electronically adjusting the phase shifter 68. The frequency stored may be continuously read out via coupler 60 to a RF sink 64, and a wavemeter 76 indicates the frequency. The Gunn effect oscillator 30 may include a Gunn effect device 150 (Fig. 5A), a strip transmission line 155, an adjustable short 170 for tuning, a transition from the strip line 155 to a coaxial line, r.f. decoupling capacitors 172, 182 and a trigger pulse generator 160 (38, Fig. 3A) which may be an emitter follower circuit driven by a pulse generator. In a modification the pulse generator 160 may provide a continuous voltage level. A swept frequency response of the memory may be obtained by applying a frequency swept signal to the input coupler 44 while the output is obtained by a crystal detector at the output coupler 60. Reference has been directed by the Comptroller to Specification 1,153,457.

Abstract: 1288465 Control of A.C. motors; protective arrangements BORG-WARNER CORP 12 Aug 1970 [11 Sept 1969] 38878/70 Headings H2J and H2K  In an over-current and under-current protection system for a three-phase motor 15 employing current transformer 25 connected to detectors 132-134, closure of switch 103 energizes lamps 143-148 for operating relays 127, 130, when associated light-sensitive semiconductor switches 136-142 are gated-on. Since the phase currents for the motor are all below a preset high level at this stage, lamps 144, 146, 148, gate-on switches 142, 140, 137, to energize relay 127 whereby contacts 127a open to de-energize relay TR1. Start button 75 is depressed to energize relay R2 which causes relays 58, 59, to close a main switch 29 in the motor circuit. A delay relay TR2 is energized with the relay R2 and. provided that the phase currents are above a lower set point before the expiration of the delay in the relay TR2, lamps 143, 145, 147, illuminate all the switches 141, 138, 136, to energize relay 130. Contacts 130a close to energize relay TR5. Thus, at the end of the time delay, contacts CRT2b open but the relay R2 is still energized through contacts CRT5a. The system is shut down if the phase currents do not exceed the lower set point at the expiration of the TR2 time delay.  If any phase current exceeds the preset high level, the light from one of the lamps 144, 146, 148, will be blocked by a shutter to de-energize relay 127 so that contacts 127a close to energize relay TR1. If the overload is not transient, relay ULR opens contacts CLRa to interrupt the circuit for relay R2 and shut down the equipment. If any phase current falls below the preset low level, relays 130, TR5, and R2 are de-energized to disconnect the motor.

Abstract: 1295184 Hydrostatic transmission SOC ANON AUTOMOBILES CITROEN 5 Oct 1970 [17 Oct 1969] 47322/70 Heading F2C An hydrostatic transmission comprises a barrel generator 1 and a receiver or load apparatus 12 although the use of the units may be reversed or a reversing valve may be introduced between the units to reverse the direction of the output drive. Fluid losses during running are replenished by the provision of auxiliary ports 40, 45 in the distributer plates 11, 26, which communicate with orifices 39, 44 leading to the cylinders 6, 18 and to pipe lines 42, 46 connected by non-return valves 43, 47 to a reservoir 41. The normally high pressure duct 31 connects ports leading to the cylinders and a normally low pressure duct 30 similarly connects the cylinders and since the fluid passing in the duct 30 is less than that passing in 31 by the amount of the losses some suction will be produced as the piston 7 is withdrawn in the cylinder 6 of the generator and fluid is thus sucked through the non-return valve 43, which in these conditions is open, from the reservoir 41. If the use of the units is reversed the change of pressure in the ducts 30, 31 will open the valve 47 and close 43 so that make-up fluid passes through the pipe 46 to the port 45. An accumulator 50 for operating servo means has fluid diverted from the high-pressure duct 31 through a pressure stabilizing valve 52. Excess pressure in the accumulator forces down a non- return valve 59 and then a valve member 52 to release fluid to the reservoir 41 via port 65, passage 67, passage 68, groove 57 and chamber 55 while a pressure drop allows a spring 54 to raise the valve member 52 to connect the circuit 51 to the accumulator via port 58, groove 57, passages 68, 67, groove 66 and chamber 61. In a modification the accumulator is supplied from the non-return valve unit 43, 47.

ERDOEL RAFFINERIE MANNHEIM GmbH 30 Dec 1970 61872/70 Headings G1N and G1S Leaks in a pipe-line 1 are detected by measuring the rate of change of the difference of flow rates at the input and output ends of the pipe-line. Transducers 11 deliver electrical flow-rate signals proportional to the roots of the pressure drops across restrictors 2, 3. Bridge circuit 4 forms the difference the output of which is differentiated at 5. The differentiated signal is recorded at 9. If it exceeds a given value set at 6 a selfholding relay actuates warning lamps and a horn, stops the pump 7, and closes all the valves 8 along the pipe-line. The apparatus thus responds to a sudden change in flow conditions in the pipeline, but not to slowly varying changes. (For Figure see next page)
