Title: Data processing systems employing semiconductor compatible charge transfer devices
IPC: H01L27/105
Filed: 1974-07-01
Abstract: 1469565 Shift register storage systems TEXAS INSTRUMENTS Inc 1 July 1974 [2 July 1973] 29003/74 Heading G4C The system has an input diode for entering data into an associated shift register, and an output diode charge sink connected to a detector which detects the charge on the last stage of the associated register and produces a voltage corresponding to the bit state of that stage. The or each register is a charge transfer device, e.g. in charge coupled or bucket brigade configurations. The various integers are formed on a single semiconductor chip. The chip additionally may also carry clock circuitry providing non-overlapping pulse trains for the input circuit and detector, and carries clock circuitry providing overlapping pulse trains for the charge transfer device. Metal insulated semiconductors are used. In one arrangement there is a single set of three charge coupled device registers stepped at <SP>1</SP>/ 3  bit rate by overlapping clock trains # 1 , # 2 , # 3  and connected via diodes 88a-88c to input circuitry as shown in Fig. 4. The IGFET input circuit, which may be on the chip, receives a clock train # which is one of the two non-overlapping bit-rate pulse trains #, #. When a bit is received at input 80 during a clock pulse # charge is transferred to the first stage of that register which is currently receiving a clock pulse # 1 , # 2  or # 3 . It is transferred to the next stage when clock pulses applied to these stages overlap. The next input bit will pass into the first stage of the next register, and so on so that the pulses are evenly distributed among the registers. In the detector, Fig. 6, the diodes 100a-100c, which are connected to the final stages of the registers, are precharged during a clock pulse #. During the following, pulse # charge is or is not transferred to the stage currently receiving a pulse # 1 , # 2  or # 3 , dependent upon the state of that stage. Voltage Vj varies accordingly and a corresponding voltage appears at the output to form one bit of the bit-rate output signal. There may be several sets of registers on the chip. The output of each register may be fed back to its input or to the input of the adjacent register. Input data is directed to a register selected by address signals (Figs. 2 and 3, not shown). In a further arrangement (Fig. 9, not shown) the input and output bit-rates are twice the frequency of the clock trains #, # and two sets of registers are used in parallel, alternate input bits being delayed by one bit period so that a delayed bit is applied to one set simultaneously with the application of the following (undelayed) bit to the other set.

Title: Improvements in or relating to sonar systems
IPC: G01S7/526
Filed: 1966-06-29
Abstract: 1,149,017. Sonar systems. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. 29 June, 1966 [29 June, 1965], No. 29133/66. Heading H4D. In a sonar system in which frequency modulated pulses reflected from targets are received by an arrangement having a plurality of signal channels respectively associated with different directions of reception, the reflected signals are recorded at the rate at which they are received, played back in sequence at a rate greater than the recording rate and applied through a frequency-changer to a pulse compression network supplying compressed signals to means for determining target range and bearing. In the embodiment of Fig. 3, echo signals received by transducer array 3 in response to a frequency swept pulse transmission from transducer 2 are applied to matrix 16 which interconnects the receiving transducer outputs through phase-shifting networks and has N outputs 4 to 10 on which signals appear if the echo signals are received from associated predetermined directions. Magnetic drums 21 and 22 are driven alternately one at a " low " speed and the other at a " high " speed which is N times the " low " speed by motors 27 to 30 acting through clutches 23 to 26 which are actuated together with ganged switches 18 such that in one sounding period echo signals are recorded, by means of recording heads 19 or 20, on one drum and in the next sounding period are recorded on the other drum, recording being effected at the " low " speed. While echo signals of one sounding period are being recorded, those of the preceding sounding period are played back at the " high " speed and the recorded signals in the N channels are reproduced by heads 33 or 34 and sequentially fed by means of rotary switch 37 through a frequency-changer stage 41 and a pulse compression network 13 to a cathode-ray tube 14 as bright-up pulses for a range-and-bearing display. Switch 37, a switch 36 controlling the actuation of clutches 23 to 26, and a switch 38 feeding a prerecorded frequency swept signal from a track on drum 21 or 22 to a driving stage 43 for the sonar transmitter 2 are synchronized to rotate at half the " slow " speed of the drums and are synchronized with the radial and angular sweeps of display tube 14. A supplementary pre-recorded track on each of drums 21 and 22 may provide the local oscillation frequency for frequency-changer 41, and the pulse compression network may be an acoustic delay line. In a modification (not shown) the two drums 21 and 22 may be replaced by a single drum used alternately for recording and playback.

Refrigerating. absorptiom machinesand systems for. - Refrigerating apparatus of the kind in which cold is produced by the evolution of refrigerant vapour from solution comprises a generator-absorber a, absorber b, and an evaporator c provided with an ice cell, the generator-absorber communicating through a water-cooled pipe e having a lightly constructed valve f with the absorber which communicates through a pipe g having a vent g<1> with the evaporator. The evaporator is connected by a pipe h with the generator absorber, and the generator-absorber and absorber are provided with cooling-water coils a<1>, b<1> respectively. The apparatus is preferably exhausted and the generator-absorber charged with a solution of ammonia in water. At the beginning of generation, solution is forced through the pipe e into the absorber until the lower end of the pipe is uncovered whereupon vapour only passes into, the absorber. At the end of generation, cooling- water is passed through the coil in the generatorabsorber thus reducing the pressure in the evaporator and the absorber and effecting the ebullition of the solution in the absorber and the conveyance of the solution through the pipe g into the evaporator, the action being assisted by the injector n. The evaporator is provided with trays i from which the solution, weakened by the evolution of refrigerant vapour therefrom, flows into a substantially closed well k. The well overflows into a compartment of the evaporator formed by a partition l and at the end of evaporation returns through the vent g<1> in the pipe g to the absorber. The partition l is provided with a syphon m to permit the return of solution to the generator-absorber through the pipe h in the event of undue, prolongation of the heating of the generator-absorber and consequent passage of solution through the vent g<1> into the evaporator. Alternatively, an opening may be formed in the partition or a float-valve may be provided. The generator-absorber may be heated by a gas burner or electrically and means dependent on the flow of cooling-water or clockwork mechanism provided to control the heater. The cooling effect produced in the evaporator may be used to cool brine and partly to cool the water supplied to the coils a<1>,b<1> Specification 306,879 is referred to.

[Also in Groups XXXVII and XXXIX] A thermal cut-out comprises a blade 2 of semi-conducting material against which a contact 1a formed on the end of a coil spring 1 is pressed. The blade rests against a support 3 which has a hole 3a opposite the contact 1a. When the current through the spring, blade and support exceeds a certain amount, the blade disintegrates and the contact passes into hole 3a to break the circuit. A number of cut-outs are shown in Fig. 1 bearing on a common blade, each contact 1a being surrounded by insulation 1b so that only the end contacts the blade. The spring may comprise a blade pressing on contact 1a and the latter may engage an alarm contact on passing into hole 3a (Fig. 2, not shown). In Fig. 3 movement of a blade spring 1 on disintegration of blade 2 allows a spring-blade 6 to break a circuit or release a mechanical stop. The blade 2 may comprise paper pulp mixed with pulverized charcoal. Fig. 4 shows how a cut-out according to Fig. 1 may be used to indicate the functioning of line-selectors in an automatic telephone system. The relay sets N1 ... Nn of the selectors S1 ... Sn have auxiliary contacts connected to the contacts T1 ... Tn of the cut-out, so that the operation of each relay causes the corresponding cut-out contact to burn a hole in the blade B to indicate that it has operated. Regular replacement of blade B will provide a continuous indication whether the relays are functioning.
