Abstract: 1,273,790. Analogue to digital converters. SOLARTRON ELECTRONIC GROUP Ltd. 14 Aug., 1970 [25 Sept., 1969], No. 47334/69. Heading G4H. In a dual-ramp A/D converter an unknown voltage V I  is introduced through an input resistor 11 to a summing circuit, preferably an integrator 12, 13, the output V 0  from which is compared, at 14, with a sawtooth waveform V D  generated at 15, the comparator 14 causing a flip-flop 18 to change its state on every occasion when V 0  equals V D , the flip-flop 18 in its first state closing an F.E.T. switch 20 thereby admitting an opposing reference voltage V R  through a resistor 21 to the integrator 12, 13, and also opening a gate 22 admitting pulses from a clock source 16 to a counter 23. The counter 23 is cleared every 100 periods of the waveform V D  and its contents transferred to a staticizer 24 and read out is effected on number tubes or print-out. In a modification, Fig. 3 (not shown), a square waveform from a flip-flop (29) is introduced at the input of the integrator, the output from which is compared with a constant voltage, and in both embodiments an overload logic circuit 26 senses whether the flip-flop 18 is in its first state at the beginning of a cycle of operation and provides a warning in this event that V I  is overloading the instrument.

Title: Special instruction processin g unit and a data processing  system embodying the same
IPC: G06F7/76
Filed: 1973-10-10
Abstract: 1429323 Data processing systems DIGITAL EQUIPMENT CORP 10 Oct 1973 [10 Oct 1972] 47348/73 Heading G4A The system includes a central processor and a separate module for processing instructions forming a distinct class. The class may consist of floating point instructions, for example. An instruction processing cycle is initiated on the arrival at the modules of a transfer signal generated by the central processor when it decodes an instruction in the said class. The module includes a control unit which processes each instruction in a series of processing cycles. During each cycle the unit generates control and synchronizing signals and then prevents a further cycle until the next transfer signal is received. The generation of the control signal is inhibited in the final processing cycle. The synchronizing pulse is passed to the central processor which reverts to a normal operating sequence and calls for the next instruction, which may be processed concurrently with the processing cycle occurring in the module. Several modules may be connected to the central processor, each module being pertinent to a respective class of instructions.

Title: Filling the anode cup of a galvanic primary cell with a depolariser mass
IPC: H01M6/02
Filed: 1975-11-18
Abstract: The cell cans (5) of galvanic primary element are supplied with depolarisation mix (1) in at least two strokes of a die (8), the mix being compacted with the aid of a pressure controller at a predefined compaction pressure. During the first stroke, precompacted depolarisation mix (1) from the previous charging operation, together with further mix (1) is pushed, as a mix plug (13), by the die (8) from a mouthpiece (4) over which the cell can (5) is placed, into the cell can and is compacted. During the last stroke, the die (8) in each case supplies an excess amount of depolarisation mix (1) and compacts it in the mouthpiece (4) and the cell can (5). That part of the depolarisation body thus produced which is positioned in the mouthpiece is separated and supplied to the next cell can (5) as a mix plug (13). This makes it possible to manufacture, independent of the structure and flowability of the depolarisation mix, depolarisation electrodes whose weight and density is kept within narrow tolerances. <IMAGE>

Abstract: 1528488 Fluid-pressure servomotor systems GARRETT CORP 25 Nov 1975 [25 Nov 1974]  48382/75 Heading G3P The pressure in a compartment 12 having an inlet 114 and an outlet 78 is controlled by a valve 76 actuated through a relay valve 20 by pressure changes in a chamber 128 connected through a manually adjustable valve 134, a chamber 126 and a restricted orifice 150 with the compartment 12. Pressure in the compartment 12, which may be a small aircraft cabin, is thus prevented from changing as rapidly as it would do in previous arrangements in which the relay valve is connected with the chamber 126. An outlet 168 from the relay 20 and an outlet 152 from the chamber 126 are connected to a source of vacuum, the outlet 152 being controlled by a diaphragm-actuated valve 32, 51 having a manually adjustable loading comprising a light spring 48 and an evacuated bellows 46. A compartment (169) Fig. 3 (not shown) may be provided below the diaphragm 156 of the relay valve 20 to communicate with the compartment 12 to improve transient response and the lower surface of this compartment may be formed by a diaphragm (271) Fig. 4 (not shown) to receive a feedback signal from the valve 18. The relay of Fig. 5 (not shown) provides improved stability and includes an adjustably-loaded diaphragm communicating with the chamber (128)  and with the valve 18, and a further spring-loaded diaphragm also communicating with the latter and with the compartment through a restrictor (367) both diaphragms being coupled to the relay valve (362).

Title: Method of grinding gear shaper cutters
IPC: B24B3/34
Filed: 1964-11-30
Abstract: 1,026,299. Gear-cutters; grinding wheel. FELLOWS GEAR SHAPER CO. Nov. 30, 1964 [July 30, 1964], No. 48641/64. Headings B3D, B3K and B3L. A method of forming a gear shaper cutter comprises rolling the cutter past a rotating tool to generate an active involute portion and a modified portion on each tooth, relatively reciprocating the tool along the teeth, and relatively feeding the tool depthwise of the teeth along a predetermined curved path so that, when the cutter is subsequently sharpened, the relative positions of the portions of the teeth remain unaltered. The cutter 1, Fig. 4 (not shown), to be ground is fed along a path P-P against the face of a grinding wheel having a plane surface 3 to generate the involute and a conical face L-L to generate the modified cutter-tooth root which, in use, produces a gear with teeth having involute-chamfered tips. The wheel is fed in along a path E-E, Fig. 3 (not shown), the path being concave when the cutter is for external, and convex for internal, gears. The wheel is set at an angle to obtain side clearance for the teeth, the angle being increased when helical cutters are to be ground.

Filed: 1974-11-13
Abstract: 1458848 Slip couplings J E KOPP 13 Nov 1974 [19 Nov 1973] 49089/74 Heading F2U A friction coupling which slips on overload comprises a shaft 1 with which an annular member 4 rotates, the member 4 having a ring 8 rotatationally secured to it, and biased towards it by screws 5 and springs 6 respectively to clamp segmental friction bodies 10 between the ring 8 and member 4 and so transmit rotation to a shaft 13. In the embodiment shown a resilient member 3 is fixed between shaft 1 and member 4 to accommodate misalignments of shafts 1 and 13. Screws 11 connect segments 10 to a hub 12 on shaft 13. Adjustment of screws 5 alters the clamping force, two sets of friction segments may be provided, a ring through which screws 5 pass being between these (Fig. 4, not shown). The coupling of member 4 with a hub 2 on shaft 1 can be by teeth, these accommodating misalignments (Fig. 3, not shown). Alternatively a resilient coupling can be between shaft 13 and the segments 10. The use of segments 10 facilitates dismantling.

Title: Zero suppression circuit
IPC: G06C19/04
Filed: 1970-10-15
Abstract: 1323763 Zero suppression MOHAWK DATA SCIENCES CORP 15 Oct 1970 [15 Dec 1969] 49118/70 Heading G4H In a high speed printer, selectively controllable zero suppression circuits 20a-20n are provided, to prevent the printing of unwanted zeros. Data to be printed is fed to store 6 and then to a series of buffer registers 8a-8n each controlling one column of print. The data then passes to zero detectors 9a-9n and comparators 10a-10n. The other input of comparators 10a- 10n is supplied from a counter 13 which is incremented by the output of a magnetic clock pulse generator driven by the print drum 1. The counter is reset by a pulse produced once per revolution by the clock pulse generator. When agreement is obtained between the inputs of comparators 10a-10n the stored data to be printed agrees with the character on the print drum in the print position, and the print hammers are actuated via AND 16a-16n and drivers 3a-3n. AND gates 16a-16n are inhibited on alternate clock pulses via inverter 19 to permit the paper to advance. The AND gates 16a-16n may also be inhibited on lines 28a-28n by zero suppression circuits 20a-20n. Zero suppression.-The output of zero decoders 9a-9n which detect the presence of print zero data in buffer register 8a-8n, is fed to AND gates 20a-20n. If zero suppression is not required in particular columns, appropriate ones of contacts 25a-25n are closed, inhibiting the appropriate AND gates 21a-21n via inverters 26a-26n. If contact 25a is open and a zero is indicated on line 11a an inhibit signal is applied to AND gate 16a on line 28a, and an enabling pulse is supplied via OR gate 23 to AND gate 21b. Thus for zero suppression to be produced by circuit 20b either a zero must be present on line 11a or contact 25a must be closed inhibiting the operation of the preceding zero suppression circuit 20a. Successive zero suppression circuits 20c-20n operate in a similar manner. (For Figures see next page.)

Foodstuffs, e.g. dough mixtures, are subjected to a pre-determined cycle of pressure changes while being mixed; as shown, dough in the mixer 1 may be subjected to an aeration phase by closing both the valves A of the pump 7, or a reduced pressure phase by closing both the valves B. The energy consumption of the motor during each phase may be measured by a walt-hour meter 14 (see Fig. 2, not shown), which supplies signals to presettable counters; these operate change-over switches, or stop the main motor, when they have counted up to their pre-set values. Alternating the various phases may be controlled on an elapsed time basis. Additional ingredients may be added during mixing.

A method of scanning films of uniaxially oriented plastics material, i.e. films stretched in one direction only, comprises arranging one film over the other so that the direction of stretch is the same for both films, heat-sealing to form a plurality of individual seals each of which lies substantially parallel to the direction of stretch and which together form a discontinuous seam extending in a direction generally transverse thereto; the length of each seal is large in comparison with its width. Articles 4 to be wrapped are placed upon suitable film 2, e.g. non-plasticized uniaxially oriented polyvinyl chloride film, and the film is wrapped about the article sufficiently to form an overlap of the film. The wrapped article is moved to a position in which it is pressed against a spreader plate 6, the overlapped portion of film being simultaneously pressed against electric impulse heat sealing means 5, 5<SP>1</SP>. The latter are provided with electrical resistance heating wires wound to and fro across the surface of glass or ceramic cooling tubes, the wires being arranged so as to lie parallel to the direction of stretch of the film material. Simultaneously with the sealing operation electric impulse heating of a resistance wire 7 severs the trailing film from the wrapped article.
