Filed: 1976-12-16
Abstract: 1511970 Pulse radar THOMSON-CSF 16 Dec 1976 [19 Dec 1975] 52666/76 Heading H4D An analog system for processing the signals of a pulse radar installation, e.g. on a guided missile, includes an analog charge transfer memory circuit 8, connected between an adder 7 and an attenuator 9, for filtering the signals contained in each "range window" during several recurrences to obtain the mean value of the signal in that window. The video signal input E is connected to a peak detector circuit 1 and via amplifier 6 to the adder 7, and the filtered signals are available at output S, whilst input Y receives the synchronization signals of the radar. Circuit 8 receives square control signals through connections 11, 12, from synchronization circuit 10, at the end of each "range window", for shifting the recorded information. A modification, Fig. 2 (not shown), permits control of the gain of the attenuator 9 to compensate for variations in circuit 8.
Patent GB-529459-A (GB)
Abstract: 529,459. Gyro-magnetic compasses. SOC. ANON. ATELIERS J. CARPENTER. May 31, 1939, No. 16080. Convention date, June 4, 1938. [Class 97 (iii)] In a magnetic gyro-compass wherein a gyroscope is used for maintaining an orientation frame during short periods in a mean direction corresponding to that of the magnetic unit, the device for setting the gyroscope is arranged to have an effective action only when the angular spacing between the gyroscope and the magnetic unit is of small amplitude, whilst the return movement of the gyroscope towards the direction corresponding to that of the magnetic unit is very slow. As shown, the precession frame 18 carrying the gyroscope rotor 17 is mounted on horizontal pivots 28 within an orientation frame 1 which is rotatable on vertical pivots 19, 20. The precession frame 18 carries a double set of narrow vanes 26, 27 which are subjected to the action of air jets issuing from nozzles 12, 12<SP>1</SP> the air being drawn from the atmosphere by creating a partial vacuum within the casing 16. The nozzles are carried by a bell 4 rotating with the magnetic unit 2. Slow deviations between the gyroscope and the magnetic unit (such as may be produced by precession or driving) are corrected by the restoring influence of the air jets acting on the narrow vanes 26, 27. If great deviation occurs (such as may be produced by the action of an horizontal acceleration acting on the magnetic unit) the narrow vanes do not remain under the action of the air jets and the axis of rotation of the gyroscope is not deviated appreciably from the meridian plane, that is, the setting effort on the gyroscope ceases during periods of great relative deviation. If a disturbing resistance occurs to interfere with the rotation of the orientation frame 1 about its vertical axis during precession of the gyroscope, a semi-annular screen 25 on the precession frame 18 will uncover one of two air outlets 24 formed in the orientation frame thereby causing a reaction which will help the orientation frame 1 to overcome the disturbing resistance. The air is led to the outlets 24 by a pipe 21 supplying air to the driving nozzle 23 of the gyroscope. The magnetic unit is hung by a cardan joint from the bell 4 which is pivoted within the orientation frame and is in communication with the atmosphere. Two graduated compass cards 13, 14, are secured respectively to the magnetic unit 2 and to the orientation frame 1, the card 14 (enclosing the magnets) being made of copper. A compass card 30 may be placed at the apex of the orientation frame.

Abstract: 1530632 Delta modulation systems INTERNATIONAL BUSINESS MACHINES CORP 29 Dec 1975 [20 March 1975] 52957/75 Heading H3H In a delta-modulation transmission system a "pseudo-random" noise is substituted for the data stream as the decoder input to prevent "dead line" when transmission time sharing or echo suppression takes place. In a companding system when the step size of a predicting integrator 2 in the encoder falls below an activity threshold level the transmission line is reallocated and information to that effect 9 sent by separate line switches the noise generator 13 output to the decoder. In an echo suppression system (Fig. 4, not shown) the noise generator is situated at the transmitting end. The randomness of the noise is constrained so that not more than a predetermined number of similar bits are consecutive.

Title: Fluid pressure responsive valve
IPC: G05D16/10
Filed: 1977-12-23
Abstract: In the safety shut-off valve, the flow of medium in the presence of an impermissible pressure on the outlet side of a gas-pressure regulating system is shut off automatically. In this arrangement, a plurality of elements are combined in one housing to give a functional unit. The force of a closing spring acts on a release mechanism. The release mechanism comprises an actuating rod (1), arranged at the upper end of which is a valve plate (2) and, in the central region (1a) of which are arranged a guide bush (3) and an actuating bush (4). The guide bush (3) cooperates equally with units (12) comprising springs (12a) and balls (12b) and with the actuating rod (1d) designed to correspond partially to the balls (12b), to give a first detent which bears the main load. This detent can be released in the manner of a cascade by means of a second detent, which is constructed in the same way, comprises actuating bush (4) and further balls (5) distributed around the circumference and the actuating rod (1b) designed to correspond partially to these further balls (5) but bears a smaller load. This safety shut-off valve with a large nominal width has the necessary closing force without, at the same time, imposing an excessively high load on the release mechanism. <IMAGE>

[Also in Division F1] A temperature control system has separate pumps 1, 22 for "hot" and "cold" liquid circulating circuits combined into one housing so that hot liquid can only leak into the cold liquid thus the pump needs only "cold" seals. The hot pump 1 circulates oil through an electric heater 3, 4 into parallel systems 11 heating die halves 7, 8 which oil is returned to a reservoir 14 having a water cooler 15. The second pump circulates reservoir oil through a two way spool valve 24 which returns oil directly through a conduit 25 and indirectly through a conduit 26 to mix with return oil from the die halves. The heater 4 is controlled by a dual contact thermometer 31, one contact of which cuts off the heater current at say 300‹C., and the other contact, set at a higher temperature, say 310‹C. energizes a solenoid valve 28 operating the spool valve to divert oil into conduit 26. The die halves may operate at different temperatures. The low return oil temperature, prevents steam formation in cooler 15, a low water pressure switch 18 on the coil cut off the heater current.
