Title: Apparatus for counting the number of rounds fired by a gun
Inventor: LOBELLE MARCEL JULES ODILON
IPC: H03K21/02
Filed: 1964-05-12
Abstract: 1,092,502. Counters. M. L. AVIATION CO. May 12, 1965 [May 12, 1964], No. 19746/64. Heading G4D. [Also in Division F3] A device 3 attached to the muzzle of a gun barrel 1 counts the number of shots fired. Each bullet acts on the magnetic field of a coil to generate an impulse which steps on a counter. The coil 12 is connected to a transistor oscillator the frequency of which is stabilized by an adjacent coil. Disturbance of the field triggers a monostable circuit which controls the counter. A capacitative pick-up may replace the coils.

A hollow model (Fig. 1) has portions, representing mouth, eyes and hair, transluscent through which light from an internal lighting unit (Fig. 2) is visible, the unit including means to vary the lighting effect. The model comprises an opaque moulding 1, having openings 5, in which glass eyes 7 are mounted, and transluscent portion 6. The cranium portion is represented by a wire cage 2 (Fig. 2), or by a smooth transparent or transluscent dome, over which a transluscent wig 4 is fitted. Lighting is by two groups of four lamps 14, mounted on two legs of bracket 12, each group being supplied through its own bi-metallic strip switch mechanism (Fig. 3, not shown). Each switch alternately supplies each pair of lamps in its own group, and these lamps are of different colours. The switches are independent, so a random lighting effect is produced. Ear lobes (not shown) can be made transluscent to illuminate jewellery thereon, or could be formed to resemble jewellery.
Patent GB-741776-A (GB)
Title: Improvements relating to sewing machine drives
IPC: D05B69/22
Filed: 1953-07-17
Abstract: 741,776. Sewing-machines. SCHWAB, M. July 17, 1953 [July 25, 1952], No. 19918/53. Class 112. [Also in Group XXIV] A sewing-machine drive shaft 10 is driven from the shaft 4 of a main motor through a disc clutch 2, 16 and braked by a disc-brake 16, 17 which latter is automatically released when the shaft 10 stops, to permit subsequent slow continuous or stepped rotation to a set position, e.g. with the needle up or down, by an auxiliary drive from either the main or a separate motor H, Fig. 7. To start, the main clutch 2, 16 is engaged and the brake 16, 17 released by turning a lever 15 acting on a flange 12 secured to a bearing-sleeve assembly 11 supporting the shaft 10, which thus moves rightwards. To stop, the lever 15 is released, permitting a spring 18 to declutch and apply the brake. When the machine stops, a centrifugal switch 46, Fig. 7, on a separate shaft 45, driven by the machine, closes a relay 50 energizing a magnet-winding 19, Figs. 1 and 7, which attracts an armature 24, connected by pins 20 to an auxiliary clutch-disc 21, which moves to the right, engaging and taking along a complementary clutch-disc 23, pinned on the shaft 10 which latter is also moved to the right but only to an intermediate position in which both the main clutch 2, 16 and brake 16, 17 are disengaged. Closure of the relay 50 also energizes the auxiliary motor H which, through spur, belt or worm-gear 25, 26 turns a sleeve 27 on which the auxiliary clutch disc 21 is splined, so that the shaft 10 is now driven at reduced speed, which persists until the circuit of the relay 50 is broken, to switch off the auxiliary motor H and re-apply the main brake 16, 17. This occurs when one or other of two insulating strips 48, 49 on a conducting disc 47, carried by the shaft 45, reaches a circuit-completing contact S, the operative strip 48 or 49, which determines respectively needle up or down positions, being selected by shifting the contact S radially, through a Bowden cable B, by a subsidiary pedal E on the main starting pedal F. In Figs. 3 and 4, not shown, the brake is released by a solenoid which turns the stationary brake plate, causing it to ride up a helix on the fixed housing, and thus withdrawing it axially from the shaft-disc. In Fig. 5, not shown, brake disengagement is by a solenoid-operated subsidiary lever, shaped like the main starting lever 15 and arranged adjacent to it on its pivot 14 to act on the projection 12 in the same manner, but to the extent of brakerelease only. In this case the worm-sleeve 27 is permanently driven at inching speed by the main motor and is permanently connected with the shaft 10 through a wedge-type one-way clutch, which is overrun during normal operation, but transmits inching drive when the main clutch and brake are disengaged. The auxiliary motor may be used for stepping or inching, in which case it drives synchronously with the machine and is unitary with the contactbreaker 47-49.

Title: Improvements in the Production of Patented Steel Wire
IPC: B21C47/26
Filed: 1967-05-01
Abstract: 1,180,991. Making steel wire. SCHOLEMANN A.G. 1 May, 1967 [7 May, 1966; 26 Oct., 1966], No. 19961/67. Heading B3A. In a method of making patented steel wire, wherein the wire after leaving the last roll stand 1 is deposited in non-concentric overlapping turns upon a conveyer 5 at a temperature above the austenite conversion temperature, and is cooled by controlled means until the conversion of the wire texture to ferrite and pearlite is finished, the wire, after being deposited upon the conveyer, is maintained above the austenite conversion temperature until the wire texture has attained a grain size not greater than 5 on the ASTM scale. The rolled wire after leaving the roll stand 1 passes through a wire feeding device 2 and is coiled by a tube 14, which rotates about a horizontal axis. An edge 4 tilts the coils horizontally on to the conveyer 5, which passes through a tunnel 6. The laying device 3 and tube 14 are axially movable and guiding tubes 10, mounted on arms 11, are selectively movable into alignment with the device 2, Figs. 5, 6 (not shown). Hence the length of the tunnel 6 may be varied and so the time between coiling the wire and passing it into a cooling tract 7 varied thereby controlling the grain growth of the wire material. The tunnel may be thermally insulated or have heat supplied, either electrically or by gas, the latter being adjusted to provide a non-oxidizing atmosphere. The controlled cooling of the wire is achieved in a tract 7, which may be a lead or salt bath or a fluidized bed. Preferably a fluidized bed is used and it comprises a gas permeable plate, through which a gas is passed, the gas fluidizing a layer of particles of the cooling medium. The space under the plate is divided into chambers, into which the gas is supplied at different temperatures so that the wire passes through a fluid of increasing temperature. Steel wires of low carbon content may be cooled in the wire feeding device 2 down to about 600‹ C. or lower. In this case the wire is not passed through the cooling medium in the tract 7.

Title: Process and apparatus for conveying liquids containing gases
IPC: B67D1/12
Filed: 1972-04-28
Abstract: 1376056 Dispensing liquids GETRANKE GmbH 28 April 1972 [30 April 1971] 19968/72 Heading A4T Gas-containing liquid, e.g. beer, is conveyed from a storage container, e.g. barrel 1, to tap 15 via intermediate container 8. The barrel is under gas-pressure sufficient to feed beer to pump 4 which supplies beer to the intermediate container. The intermediate container is under a higher gaspressure than the barrel 1, which pressure forces the beer to the tap. Level controller 13 controls the pump, and beer pumped in is introduced below the lowest level allowed by the level control. When the barrel is empty, device 3 signals this acoustically or optically to 5 adjacent the tap, and turns off the pump motor. Check-valve 7 prevents back-flow of beer. Gas cylinder, e.g. CO 2 , supplies gas via pressure-reducing valve 18 and check-valve 24 to pressure conduit 19 having a pressure-relief valve 23, and thence to intermediate container 8. Gas to apply pressure to the barrel 1 is obtained from the conduit 19 via pressure-reducing valve 21 and check-valve 25. The supply line 14 to the tap 15 may pass through cooling coil 16.

Title: Improvements relating to means for determining and indicating the electrical conductivity of fluids
IPC: G01N27/04
Filed: 1925-08-08
Abstract: 260,366. Gillmor, R. E., (Ruben, S.). Aug. 8, 1925. Resistances, measuring; liquid resistances.-The electrical conductivity of fluids is determined by means of a current meter in series with electrodes immersed in the flud, which electrodes are mounted so that the gap between them varies with the temperature so as to compersate for temperature effects. Th invention is particularly applicable for estimating the impurities in solution in boiler feed water. The electrodes 13, 14 are of platinum, one electrode 14 being carried by a U-shaped thermostatic strip 12. The electrodes are carried by a tube 26 and are protected by a metal guard 28 detachably connected to the end of the tube 26 and provided with holes to permit free flow of water. The tube 26 passes through a gate valve 20 into which is screwed a tube 21- connected through a T-piece with the pipe line where the water impurity is to be measured. The tube 26 is retained in position by means of a trigger 24 engaging a projection 27, and may be withdrawn for inspection of the electrodes by depressing the trigger and partly withdrawing the tube 26 to bring the guard 28 clear of the gate. The valve 20 into which is screwed a tube 21 connected pletely. A chain and wing nut may be provided for preventing complete withdrawal of the tube until the valve is closed. The electrodes 13, 14 are in series with a millammeter and a source of alternating current through a transformer having a saturated core to minimize the effect of voltage variations. The transformer mav be fed from a direct-current supply through a rotary converter. The milliammeter is of the iron-cored type and has the core approximately saturated under working conditions, so that the scale is contracted at the higher current valves. Alternatively the same effect may be produced by arranging in series with the milliammeter a resistance having a positive temperature coefficient such as a metal filament lamp. The voltage across the electrodes is comparatively high to minimize the effect of gas occlusion. A condenser may be arranged in parallel with the secondary coil of the transformer for adjusting the transformer to the saturation point at the minimum voltage. The carbon dioxide or sulphur dioxide content of flue gases may be determined by first absorbing them in a vapour, which is then condensed and tested as described above.

Title: Improvements in or relating to electrical phase or frequency discriminators
IPC: H03D13/00
Filed: 1948-07-27
Abstract: 653,703. Phase difference and frequency measurements. GENERAL ELECTRIC CO., Ltd., and BRYDEN, J. E. July 27, 1948, No. 20078. [Class 37] [Also in Group XXXVIII] In a phase or frequency discriminator two direct voltages dependent in relative magnitude on relative phase, relative frequency or absolute frequency of an A.C. source are successively and repeatedly switched to the input of an amplifier the output of which is successively and repeatedly switched, in synchronism with the input, to a pair of electrical devices giving an indication or effecting a control. In a correspondence control system a transmitter 17 and a receiver 22 are phase-shift potentiometers. e.g. of the type described in Specification 632,007, [Group XXXV], supplied from a sixphase source 20 which may be derived from a single-phase source as described in Specification 642,855, [Group XXXV]. The output of the transmitter, phase-shifted by 90 degrees in a network 23 including a valve buffer stage, and the output of the receiver are applied to a circuit including a centre-tapped transformer 2 and rectifiers 4 developing across resistances 5 two direct voltages which are equal when transmitter and receiver outputs are in phase but differ in magnitude in one sense or the other according to the sense of phase deviation. A contact 8 of a vibrator (not shown), operating at 60 cycles per second, applies the voltages successively and repeatedly to a two-valve A.C. amplifier 10, the output of which is applied to a triode valve 13 energizing relays A and B. The relays are successively and repeatedly shortcircuited by a contact 14 of the vibrator operating in synchronism with contact 8 so that each of the voltages across resistances 5 controls the operation of a different one of the relays. When the voltages are equal neither relay operates but when one or other voltage is the larger upon phase deviation the corresponding relay operates and remains operated to close its contact A1 or B1 and operate a reversible electric servomotor 16 in the appropriate direction to bring the receiver into coincidence with the transmitter. It may be so arranged that when the voltages are equal both relays are operated. To reduce hunting a slow-to-operate relay may be included in circuit with relays A and B to reduce, in its inoperative position, the speed of the servomotor so that the latter only operates at normal speed when the deviation is above a predetermined value for a predetermined period. Lamps may indicate presence or absence of correspondence and the sense of deviation.

Title: Improvements in or relating to sealing devices for glass, earthenware and like bottles and receptacles
IPC: B65D55/06
Filed: 1924-08-25
Abstract: 243,430. Henkes, A. Aug. 25, 1924. Sealing devices for stoppers and other closures. -A sealing device for glass, earthenware, and other bottles &c. and of such initial form as to cover wholly or partially the top of the closure is made of glass, metal, or other material which requires to be heated before the device can be deformed to fix it in position, rupture of the device being necessary before access can be had to the cotents of the bottle &c. A bottle seal comprises a top 2, Fig. 1, and a cylindrical or conical body 1 from which depend prongs 3 adapted when in a heated condition to be forced into close contact with the neck of the bottle which has been previously wetted or otherwise treated to insulate it from the heated seal. As shown, the lower ends 4 of the prongs 3 are bent outwards to facilitate their removal by an upward or outward thrust, but in other forms they are turned inwards to grip the recesses 10, 11, Fig. 4, in the bottle neck. In another form, the body portion 34, Fig. 13, extends below the shoulder of the bottle, its lower edge 35, which may be notched as at 35<1>, being turned beneath the shoulder. In this form, the top 37 is secured to the body portion 34 by narrow bridge-pieces 38 which render it removable therefrom to gain access to the stopper, the removal being facilitated by a raised portion or projection 39. As shown in Fig. 7, the prongs 3, 28 extend directly from the top 25 and are of different lengths, the shorter prongs 28 merely preventing lateral displacement of the seal. In a further modification, the seal comprises crossed arms 12 .. 15, Fig. 5, carrying prongs 16 .. 19. In other forms two prongs only are used, lateral extensions at the ends of the prongs preventing displacement of the seal. Such forms may be supplied and applied in a flat shape with the prongs extending outwardly from and in the same plane as the top. To ensure rupture of the prongs, they are formed either with perforations, with projections 40, 41, Fig. 15, by which they can be pulled away from the bottle, or with incisions 42, 46 which determine the place of fracture. The seal may be formed of glass, steel, zinc, alloys, or other material initially in, or capable of acquiring, a brittle condition.

Abstract: 1528164 Pulse Doppler radar MARCONI CO Ltd 9 Oct 1975 [14 May 1975] 20242/75 Heading H4D A pulse Doppler radar utilizing fast variation of p.r.f. comprises receiver signal processing circuitry including a plurality of range gates connected to the receiver I.F. output, each range gate being connected to a clutter filter which produces an output signal substantially unaffected by changes in the p.r.f. Frequency and waveform synthesizer 16 opens range gate 10 at a predetermined time after each pulse transmission, and pulse echo signals received are filtered in Gaussian band pass filter 12 which reduces the frequency spectrum of the signals and produces a lengthened Gaussian shaped output pulse. The sense of the Doppler information contained therein is obtained by quadrature mixing in mixers 14 fed with quadrature I.F. signals from synthesizer 16. Lowpass Guassian filters 18 filter out mixing products other than those centred on D.C., to produce a low frequency signal comprising pulses, the peaks of which follow the Doppler signal envelope, and a sample and hold circuit 20 is controlled by unit 16 to sample at the peak amplitudes, producing a stepped waveform at the Doppler frequency, which is unaffected by changes in p.r.f., of the received pulses, except that the samples are held for different corresponding periods. Clutter frequencies are removed in high pass filters 22, the stepped waveform is smoothed in low pass filters 24 and the Doppler signal so obtained modulates in quadrature I.F. signals in mixers 26 to produce a true phase Doppler I.F. signal at the output of vectorial adder 28.

Plates, dishes, and the like, washing.- A dish-washing rack of the kind described in Specification 304,569 comprises a main rectangular frame 11 in which is pivotally arranged a plurality of open frames 14, 16 adapted to receive the plates, saucers, or the like, to permit them to be moved singly or collectively from side to side about their pivots so as to provide a gap 25 showing the sides of the plates &c. to view. Plates &c. are slipped between the frames 16 till the lower part of the plates comes in contact with the rods 14 of the frames. When one frame is moved to the left, a gap is made which offers to view the back of a right plate and the inside of a left plate or vice versa. Both plates can be examined and sprayed or mopped as desired. One of each pair of uprights 16 is made long for use as a handle. The frames are arranged in staggered blocks 15 so that the frames can be nested together and do not foul. The whole device may be made of wood or some or all the parts may be made of metal. Metal fittings 17, Fig. 4, preferably rustproof, may take the place of wooden blocks 15. The main frame 11 is provided with four rods 19 which serve as supports and also carry longitudinal bars 20, 21 to prevent contact with wall brackets when the dish washer is removed from the sink. Transverse bars 22 &c. are fitted to act as stops and determine the angle of inclination of the hinged frames 16. A movable safety rail 25 is carried by two small bars 26 and is provided with a spring 31. In the modified construction Fig. 4, one rod 16 of each hinged frame is prolonged through its fitting 17 so as to form an extension 32 to co-operate with spaced pegs 33 serving as stops.
