Title: Loop antenna
IPC: H01Q1/36
Filed: 1967-11-03
Abstract: 1,211,723. Aerials. L.T.V. ELECTROSYSTEMS Inc. 3 Nov., 1967 [9 Dec., 1966], No. 50094/67. Heading H4A. An aerial comprises a closed core of ferromagnetic material in which two parallel rods 12, 13, Fig. 2, are joined together at respective adjacent ends by end-pieces 14, 15. The height h of an end-piece is greater than the thickness t of a rod, and the width w of an endpiece is greater than the outside spacing s of the rods. Coils 16, 17 are wound on respective rods 12, 13 and they are so connected that magnetic fluxes due to incident radio waves produce voltages which are additive, whereas the magnetic fluxes induced by a current flowing in the coils are opposed. As shown, the coils 16, 17 are of the same hand, and the finish end t1 of the coil 16 is connected to the start end t2 of the coil 17. Alternatively, the two coils may be of opposite hands, and their finish ends be connected together. Slotted conductive discs made, for example, of aluminium, may be placed over one or both of the parallel rods between the coils and the endpieces, in order to reduce flux leakages and stray couplings (Fig. 3, not shown). The coils may have equal numbers of turns which may be distributed over the entire lengths of the rods, and said rods may be of elongate form. An aerial of the kind described may be mounted on a base-plate 101, Fig. 4, on top of which is a printed circuit board shield 102, by means of dielectric material support members 106.1, 106.2, and (103.1), (103.2), Fig. 5 (not shown). A cylindrical printed circuit shield 110 rests around the aerial with its bottom rim cemented to the board 102, and it is filled with foamed material, embedding the aerial. A top printed circuit board shield 111 closes the cylindrical shield 110. All parts of the assembly above the base-plate 101 are contained in a moulded plastics cover 112. A metal tray 113 to which a lead connector 114 and fastening sockets 115 are attached, is secured to the base-plate 101, with spacers 116 intervening. The tray is filled with foamed material 117.

Title: Data processing apparatus
IPC: G06F9/32
Filed: 1963-12-19
Abstract: 1,062,780. Data processors. WESTERN ELECTRIC CO. Inc. Dec. 19, 1963 [Jan. 3, 1963], No. 50126/63. Heading G4A. In a stored-programme computer, the first instruction of each sub-routine has an associated suffix mark, selection of a transfer instruction priming error indicating means which then operates unless the next instruction accessed possesses the suffix mark. In response to a transfer instruction, the instruction decoder sets a flip-flop to enable an AND gate, and pulses a delay. If the next instruction has the suffix mark the flip-flop is reset before the delay delivers an output. Otherwise this output passes through the AND gate to indicate error.

Title: Drives for screen or headlamp wipers
IPC: B60S1/20
Filed: 1972-11-03
Abstract: 1414188 Linkwork ROBERT BOSCH GmbH 3 Nov 1972 [5 Nov 1971] 50711/72 Heading F2K [Also in Division A4] A drive for vehicle headlamp or screen wipers comprises a rotatable crank 26 and a cable 16 for transmitting movement to at least one wiper blade and which is attached at one point to a fixed location, the crank 26, or an element actuated thereby, acting laterally on the cable between its fixed point and a transmission region thereof to cause said region to reciprocate. In a first embodiment, as shown, a rocker 28 reciprocatingly pivots about axis 29 through 90 degrees under the action of a push-rod 27, the crank 26 and a shaft 25 which is driven by a motor and reduction gear 24. During pivoting, a taut cable 16, which is fixed to the vehicle at an anchor 33, is displaced by a pulley 31 on the rocker 28, causing wipers 12, which are secured to the cable 16, to move in linear opposite directions C a distance equal to twice that between pulleys 30, 31. By running the cable more than once around pulleys 30, 31 a larger wiper 12 movement results for the same pivotal movement. In a further embodiment, wiper arms are secured to pulleys, the cable being guided therearound. Thus cable movement rotates the pulleys thereby arcuately moving wipers attached to the arms. In a still further embodiment, the wiper is secured to a cable length which is fixed at both ends, one via a spring which keeps the cable taut. A sliding member on a crank rotates around a circular path of which the taut cable is a diameter. Thus, the cable bulges with the movement of the sliding member causing corresponding movement of the wiper element.

Title: Torque Limiting Screw-Threaded Fastener
Inventor: DEAN JOHN FRANKLIN
IPC: F16B31/02
Filed: 1966-11-14
Abstract: 1,172,097. Spanners. HI. SHEAR CORP. 14 Nov., 1966, No. 50978/66. Heading B3N.

Title: Range adjusting system for time measurement apparatus
IPC: H04B3/46
Filed: 1972-11-07
Abstract: 1406639 Time interval measurement WESTERN ELECTRIC CO Inc 7 Nov 1972 [10 Nov 1971 (2)] 51273/72 Heading H3H The time interval between a predetermined state of a pulse train and a test signal is determined by altering the phase of the pulse train until the interval is a minimum and then interpolating. The time interval may be a delay on a telephone line. Pulses from clock 102 are controlled in width at 103 and pass via gate 104 to divide by eight circuit 106 which has initially the dotted line output B. Positive going edges of pulse train B generate trigger pulses C (initially as shown dotted) which set bi-stable 110. The bi-stable output is fed to gate 105, to which clock pulses A are also fed. The test signal, which is delayed in phase relative to B is fed to input 115 of zero crossing detector 120 which has two antiphase outputs D (line 121) and J (line 122). Output D resets flip-flop 110 which initially has an output comprising the first pulse of train E and this pulse gates (as shown) two clock pulses (F) through AND gate 105. These pulses are fed to counter 130 and also to monostables 123 and 125. The outputs of monostable 125 (H) are of sufficient duration to prevent two clock pulses reaching divider 106 and the phase of output train B is therefore retarded to the position shown in solid lines. The output pulse from flip-flop 110 is now of duration #t-less than the period of clock pulses A. As this pulse represents a very small portion of the divider output period it is difficult to measure so the trigger pulses C are also fed to set flip-flop 111 which is reset by the antiphase zero crossing pulses J. The output of this flip-flop is a waveform (K) of fairly equal mark space ratio and this is low-pass filtered (126) amplified and the value of #t displayed on meter 128. This value is also converted to a digital signal by converter 129 and is fed to counter 131. The output of counters 130 and 131 representing coarse and fine parts of the time measurement are combined in summing circuit 132. Coincidence of set and reset pulses on flip-flop 110 may cause a large number of pulses to pass AND gate 105. Circuitry may be provided (Fig. 4, not shown) to integrate these pulses and, when the integral exceeds a predetermined value indicative of a coincidence, the time delay of a delay circuit in line 121 may be altered. The phase changing may also be carried out in a series of steps, each corresponding to the suppression of one pulse.

Title: Constant surface speed ma'hine tool control system
IPC: G05B19/416
Filed: 1970-10-28
Abstract: 1318908 Programmed control of machine tools; automatic control of linear speed GENERAL ELECTRIC CO 28 Oct 1970 [12 Dec 1969] 51307/70 Headings G3N and G3R [Also in Divisions B3 and G4] A control system for a machine tool, controls the speed of rotation of the workpiece so that the linear speed at the cutting tool is constant. A tape reader 44 feeds data to arithmetic unit 42 which has a delay line store 36. The tool drive is controlled by digital signals from the arithmetic unit to servo drive controls 46 and 48 which control motors 30 and 34. The speed of rotation of the workpiece is measured by encoder 68 and fed to speed control 49 which controls the speed of rotation of motor 20 via servo drive 50. In the speed control unit Fig.3 a digital signal representing the required surface speed is fed into multiplier 60 together with a clock frequency from clock 41, via frequency divider 66, to produce a pulse output, whose frequency represents the speed. This signal is multiplied by 1/2# in multiplier 62 and fed to variable phase counter 78. The actual speed of the workpiece is encoded by encoder 68 and fed to multiplier 64 together with a digital signal R representing the current radius of the workpiece, derived from the arithmetic unit. The output of multiplier, 64 thus represents the linear surface speed of the workpiece multiplied by 1/2#, and is fed to variable phase counter 80. The phase of the two counters are compared by a comparator 82, and a difference signal is derived representing the difference between the actual and desired surface speed of the workpiece. This difference is fed to digital to analogue converter 84 and then to the servo drive 50 for the workpiece motor 20. In a second embodiment the workpiece speed is not measured directly, but simulated from the speed control signals supplied to the variable phase counters 78 and 80.

Title: Improvements in or relating to Means for Regulating the Thickness of Rolled Products and Rolling-Mills Equipped therewith
IPC: B21B37/64
Filed: 1967-11-10
Abstract: 1,180,148. Rolling. COMPAGNIE DES ATELIERS ET FORGES DE LA LOIRE (ST CHAMOND FIRMINY, ST ETIENNE JACOB - HOLTZER), and HYDROMECANIQUE ET FROTTEMENT. 10 Nov., 1967 [19 Dec., 1966], No. 51335/67. Heading B3M. Apparatus for regulating the thickness of a rolled product is positioned in a roll stand either between a lower chock and the roll housing or between an upper chock and a screw-down, and comprises a piston 1 which is acted on by a chock E and moves within a support 2. The space between the piston and support is filled with a liquid 5 into which extends the end of a plunger piston 4. The position of the piston 4 is controlled by a servo-valve 7 and an hydraulic actuator 6. The servo-valve is in turn operated by a unit 13 in response to the measured position of piston 4 and the pressure of the liquid 5. Any change in the roll gap leads to a movement of the piston 1, and a proportional change in the liquid pressure. The piston 4 is thus caused to move axially. The liquid pressure is measured at 11, and the actual and derived positions of the piston 4 are measured at 10 by a position detector. Signals corresponding to these measurements, together with a zero shift signal, are fed to the unit 13. The unit controls the servo-valve 7 such that the piston 4 is moved in a sense to compensate for the original change in pressure in the liquid 5. A diaphragm 12 positioned between the chock E and piston 1 transmits vertical loads while absorbing lateral and rocking forces produced by the chock. The liquid 5 consists of a mixture of 20 parts by weight of calcium-soap grease, 10 parts of micron size graphite, and 2 parts of sodium tri-stearate. A second plunger piston may be used which is forced out of its bore in the event of excessive rolling pressure.
