Title: Improvements in and relating to frame counters
IPC: G03B17/30
Filed: 1969-08-27
Abstract: 1286511 Photographic cameras AGFA GEVAERT A G 27 Aug 1969 [30 Aug 1968 30 April 1969] 42723/69 Heading G2A A frame counter for a roll film having a perforation per frame has a feeler past which the film moves and which enters each perforation in the film that passes, a counting device recording the number of times the feeler enters the perforations. In one embodiment, Fig. 1, a spring rod 9 is secured to the rear wall of a cartridge 1. At its upper end two resilient arms are provided, arm 9a extending towards the film path to be engaged by a perforation, and when thus engaged is moved in the direction of film movement so that the second arm 9b carrying a pin 10 engages and moves a counting disc 7, an oblique surface (9b), Fig. 3 (not shown) associated with arm 9a meeting an oblique surface (6b) provided at one end of an aperture (6a) formed in a film path (6) disengaging arm 9a from the perforation after a movement sufficient to turn counting disc one tooth. The counting disc is spring biased to its zero position, but is prevented from rotating by a third arm 9d acting as a locking member by engaging in the toothed section of disc 7. In a second embodiment, Fig. 6, a counting disc 107 has a plurality of radial arms 110a resilient in a direction normal to the film plane. A resilient member 111 fixed to the inside of the cartride wall causes one arm in turn to be presented to the film, a perforation 103a engaging the arm and causing rotation of the disc 107 until the arm slides away from member 111 to disengage from the perforation. Member 111 may be rigid in which case the film is arched by an arm 110a until a perforation is reached.

Title: Shift registers
IPC: G11C19/12
Filed: 1964-10-27
Abstract: 1,022,970. Circuits employing parametrically excited resonators. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 27, 1964 [Nov. 26, 1963], No. 43687/64. Heading H3B. A shift register employs an input parametron 17, an intermediate parametron 19, and a pair of shift control parametrons 23, 25, in each stage. Information is written in parallel into the input parametron of each stage of the shift register by supplying an alternating current to driving line 13 so that second harmonic currents flow in sense lines 15, having a phase sense indicative of the information stored. The three substages of the shift register (input, intermediate and shift control) are excited in overlapping time sequence and while information is being stored in the input substages 17 a control signal C is applied to line 35 to prevent feedback between parametrons 23, 25 and parametrons 17. At a later time the intermediate parametrons 19 are excited and the information is passed to them from parametrons 17. After terminating the excitation of parametrons 17, parametrons 23, 25 are excited and receive the information from parametrons 19. The information is stored with opposite phases in the twoshift control parametrons. When input parametrons 17 are next excited the information is passed from the shift control parametron of one stage to the input parametron of the subsequent stage. The phase of the signal from a parametron 25 is reversed before being stored in a parametron 17, so that the two inputs to 17 are additive. The information can then be re-written into the matrix in a row adjacent to the one from which it was originally extracted, by energizing driving line 13. Circuit details. The input substage (Fig. 3) includes two non-remanent cores 40, 42 and a capacitor 50. The sense line 15 of the memory matrix is connected in series with the capacitor and windings on the two cores. Line 18 conveys the output to a core 52 coupled to the input line of the intermediate substage (Fig. 4, not shown), which is similar to the input substage. The output line is coupled in series opposition to two cores 72, 74 of the shift control substage (Fig. 5). The output lines from the two parametrons 23, 25 are oppositely wound on core 54 coupled to the input, parametron 17. Line 102 links cores 72, 74 of the shift control substage and is permanently energized with A.C. When feedback from 23, 25, to 17 is to be prevented control line 35 is also energized with A.C. in phase with that in line 102 and the additive currents drive both parametrons 23, 25 to oscillate in the same phase so that no resultant flux flow in core 54. When information is to be passed from the intermediate substage to the shift control substage winding 35 is energized in antiphase to 102 so that parametrons 23, 25 oscillate in antiphase and a resultant flux is induced in core 54.

Abstract: 1431324 Moulding composites ROSTONE CORP 21 Sept 1973 [25 Sept 1972] 44440/73 Heading B5A A thermosetting plastics is applied to a substrate by coating the substrate with an uncured but form-stable layer of an elastomer, preferably in the presence of a bonding agent for the elastomer and the substrate material, moulding thermosetting plastics against the elastomer under heat and pressure and in the presence of a coupling agent for the plastics and the elastomer, and maintaining the heat and pressure until the thermosetting plastics and the elastomer are cured and chemically bonded together. A tank 10 for a transformer 14 is made by pressing a metal sheet to form a vapour-barrier liner 18, coating the liner by spraying or dipping with a solution of an elastomer containing the bonding and coupling agents, driving off the solvent by heating, placing the liner on a male mould 22 having heaters 72, 74, placing thermosetting plastics 80 on the liner, bringing a female mould 76 having heating bands 78 over the male mould to mould the plastics over the liner, and heating the resins to cure them. The tank cover 12 is made similarly but the liner 38 has punched holes into which high and low voltage connectors 50, 62 and insert 64 for suspension of the transformer 14 in oil 16, all coated with elastomer, can be positioned in a mould and bonded to the cover when the thermosetting plastics layer 40 is moulded. To join the cover 12 to the tank a peripheral flange rests on a seal on the tank rim and a depending portion of the flange enters a peripheral groove around the tank, epoxy resin being poured into the trough to effect a seal. Fans and pump parts may be made, e.g. with the plastics layer on the inside of a metal substrate, and the elastomer may contain carbon to render it conductive and may be coated on to a plastics substrate. The elastomer may be natural or synthetic rubber, e.g. neoprene or polyurethane, and contain an amino-functional silane as the bonding agent and a methacrylatefunctional silane as the coupling agent. The thermosetting plastics may be a polyester, epoxy, allyl, or vinyl ester resin, or a mixture of polyester and allyl resins, and contain mould release agents and fillers such as glass, asbestos sisal, nylon and cellulosic fibres and hydrated alumina to reduce surface tracking.

Abstract: 1482006 Mixing apparatus ACME-CLEVELAND CORP 14 Oct 1974 [19 Nov 1973] 44510/74 Heading B1C In apparatus for mixing foundry sand with a liquid binder, the binder constituents are supplied by pipes 51, 52 to the interior of a rotor 15 whence they are projected centrifugally through vertical slots 60 in the rotor walls and strike a falling curtain of sand. The latter is controlled by a gate 29 and is directed by guide surfaces through a central opening in a member 33 to a dished member 17; the members 17, 33 form an assembly rotating coaxially with but independently of the rotor 15. The sand is upwardly directed by the dished member 17 to strike the lip 44 of member 33, by which is it redirected downwardly and falls along the inner surface of the housing 54A, 54B. The path of the sand thus passes three times through the zone of projection of the liquid binder, at 71A, 71B and 71C. The dished member 17 carries a fan blade 157 to prevent material adhering to the inner surface of the housing. Air or other gas may also be supplied through a hollow support 56A and passages 118 to fan blades 109 mounted on the member 17, and through apertures 119, 126 to the interior of the rotor 15. The housing 54A, 54B is hinged at 70 to permit replacement of a liner 94, and the members 17, 33 may also have liners. A modified rotor, Fig. 3, enables two binder components to be dispensed in parallel planes. The rotor is driven at 5000 to 15000 rev/min or at a peripheral speed of 3000 to 16000 ft/sec.

Abstract: 1,260,064. Automatic gain control; automatic phase control. LICENTIA PATENT-VERWALTUNGS G.m.b.H. 18 Sept., 1970 [19 Sept., 1969; 28 Jan., 1970], No. 44558/70. Headings H3A and H3T. In a television receiver which includes a phase comparison circuit for synchronizing a line scanning circuit and adapted to be gated at a control electrode by pulses at line frequency, and also an automatic gain control circuit also adapted to be gated by pulses at line frequency at a control electrode, the control electrode of the phase comparison circuit and/or the control electrode of the automatic gain control circuit is connected to the output of an AND circuit, adaptad to be fed by line synchronizing pulses and pulses at line frequency derived from the line scanning circuit. Video signals 2, Fig. 1 in which the sync. pulses 12 are positive-going are fed to a sync. separating stage 36 and also to the base of an automatic gain control (a.g.c.) transistor 5, from the collector of which the gain control potential is derived. Transistor 10 comprises an AND gate, sync. pulses being applied to its base from separator stage 36 and line fly back pulses to its collector from line scanning circuit 22. The pulses 19 from its emitter are passed over capacitor 14 to the base-emitter path of transistor 23 which acts as a D.C. restorer, the tips of the pulses being brought to ground potential. This waveform is fed over resistor 16 to the base of transistor 5 to render it non-conductive except during sync. pulse periods. Transistor 23 also acts as synchronizing means for the line scanning circuit 22, sync. pulses being fed into its collector from separating stage 36 via resistor 24 and capacitor 27; capacitor 24a integrates the waveform into one of sawtooth type (Fig. 2d, not shown). The arrangement is such that the a.g.c. circuit is effective even if synchronization does not occur, the gain control voltage then being derived from the whole video waveform. In a modification, the waveform from the AND gate 10, Fig. 3, are fed to the base of the a.g.c. transistor 5 via resistor 32 and biased diode 33 which provides a delay.

Two pairs of measurement values may be displayed, using electrode strips of different colours arranged alternately, or the plate 1 may be provided with alternate strips of materials which luminesce with different colours, all the strips of one colour being associated with electrode arrays for one pair of variables. Each array of electrodes is controlled by a multi-contact selector switch 5 in a self-balancing circuit, Fig. 3. A motor 13 drives the selector switch 5, a second selector switch 5a, and a potentiometer 15. An analogue input 18 for the variable being measured is compared with a voltage 19 from the potentiometer 15 and a three position flip-flop unit 17 actuates a relay unit 16 to control the motor 13 to reduce to zero the difference between signals 18, 19. The relay unit 16, once actuated, is self-holding until cancelled by a voltage 20 from the switch 5a, to ensure that the motor 13 stops at a position in which the switch 5 connects only one electrode strip to a supply.

Abstract: 1,222,918. Vehicle spring suspensions. GENERAL MOTORS CORP. 11 Sept., 1969 [27 Sept., 1968], No. 44858/69. Heading B7D. A motor vehicle has a suspension arrangement comprising a primary suspension spring e.g. a coil spring 22, acting in conjunction with an auxiliary suspension spring, the latter comprising a first liquid-displacer device 34 arranged in parallel operating relation e.g. coaxially within, the primary spring, and forming a variable-length link between sprung and unsprung portions of the vehicle, a subatmospheric pressure-energizable servomotor 28 mounted exclusively on the sprung portion of the vehicle remote from the first liquid-displacer device, and a second liquid-displacer device 30 connected to the servomotor for operation thereby for displacement or withdrawal of liquid to or from the first liquid-displacer device. In one embodiment (as shown), the arrangement is such that coil spring 22 normally supports the vehicle in a level attitude only when fully loaded, so that in less than fully-loaded conditions the servomotor 28 is connected to the intake manifold of the vehicle engine via a height-sensing valve 26 whereby the auxiliary spring acts in opposition to the coil spring to compress the same so as to maintain the vehicle in a level attitude. In an alternative embodiment (not shown), the arrangement is such that the coil spring normally supports the vehicle in a level attitude only when unloaded, so that the servomotor is operative when the vehicle is loaded to cause the auxiliary spring to restore the level attitude. The servomotor may also operate like displacer devices at an opposite end of the axle.
