Title: Telephone dial mechanism
Inventor: MYATT EDWARD RONALD
IPC: H04M1/31
Filed: 1965-06-02
Abstract: 1,133,336. Telephone impulse transmitters. STANDARD TELEPHONES & CABLES Ltd. 27 May, 1966 [2 June, 1965], No. 23486/65. Heading H4K. An impulsing cam 50 comprises vanes 53 with a wedged leading edge 54 to split impulsing springs 70, the vanes having a stepped profile so as to increase the impulse duration depending on whether the springs engage the tips, the centre portion or the roots of each vane. The impulsing springs 70 are pivoted at 74 for angular adjustment and are clamped in position by screw 76. The impulsing cam 50 is driven by a pin 61 on a gear-wheel 28 which drives a governor mechanism direct and is driven from pinion 30 by the finger wheel. A ratchet disc 40 lies between the gear 28 and the cam 50, teeth 43 engaging corresponding recesses in the cam 50. The post 61 strikes face 41 of a projection 42 of ratchet disc 40 to drive it idly as the finger wheel is wound up to a digit setting. When the finger wheel is released gear-wheel swings round to provide an interdigital pause until post 61 strikes the face 44 of projection 42 of ratchet disc 40. Further rotation of gear 28 now drives the ratchet disc which engages with the cam 50 to produce impulses. During idle motion of the ratchet disc 40 the cam 50 is held against reverse motion by a spring arm 62 engaging one or other of depressions 52 in the cam. The ratchet disc 40 and cam 50 are pressed together by a spring 60. Buffer rings 65 and 66 of a material having little friction are secured to the fixed spindle 29 to separate spring 60 from gear 28 and the disc 40 from cam 50. The base 10 of the mechanism may be a thermoplastic moulding or may be die cast. A stud 81, fast with and projecting from the central finger wheel spindle, splits off-normal springs 71, stacked beneath the impulse springs 70, when the dial is at rest.

Abstract: 1,203,854. Ultrasonic inspection devices. AUTOMATION INDUSTRIES Inc. 20 May, 1968 [9 June, 1967], No. 23830/68. Headings H4D and H4J. Apparatus for inspecting a workpiece comprises a transducer for transmitting ultrasonic energy obliquely into the workpiece surface, a spaced transducer for receiving ultrasonic energy re-radiated normally to the surface from within the workpiece, and a device for scanning the transducers over the surface. In the Fig. 1 embodiment for inspecting a weld 18 for flaws, receiving transducer 28 and angled transmitting transducers 24, 26 are reciprocated across the weld by motor 42 and mechanism 34, 36, 40 while workpiece 1,6 is driven longitudinally by rollers 37. The transducers and workpiece may be submerged in a liquid couplant or may be in direct contact or coupled by a liquid film. Transducers 24 and 26 are pulsed by transmitter 44 and their angles are adjusted such that shear waves propagate in workpiece 16. Discontinuities in the weld reradiate acoustic energy to transducer 28, whose output is fed via receiver 50 (which may incorporate A.G.C.) and time gate 52 to an oscilloscope or chart recorder 54 (comprising an amplitude threshold circuit) which is scanned synchronously with the transducer reciprocation and workpiece movement to provide a plan position indication of weld flaws. The transducers are piezoelectric and transducer 28 may incorporate an acoustic lens to give a narrow reception beam. Recorder 54 may produce either a positive or a negative record: the latter, in which a dark line recording is interrupted on reception of an acoustic signal by transducer 28, allows monitoring of the operation of the ultrasonic and recording system. In various modifications the transducers may be positioned on both faces of the workpiece, the receiving transducer may be to one side of the transmitting transducers instead of between them, and the transducer scanning may be effected by reciprocating the transducers relative to each other along guides 58, 60.

Title: Process for the recovery of emulsion polymerized polymer from the latex in which it is prepared
IPC: C08F2/22
Filed: 1964-06-10
Abstract: A resinous polymer is recovered from a latex in which it has been prepared by emulsion polymerization by coagulating the latex in the form of a shapable paste by continuously feeding separate streams of latex and coagulant into the mixing chamber of a positive displacement pump subjecting the latex and coagulant to a mixing action without exerting an abrading action on the paste thus formed and separating, washing and drying the resultant polymer. The latex may contain a styrene-acrylonitrile copolymer, or a polymer of styrene, dichlorostyrene, alpha-methyl styrene, methacrylonitrile, ethyl acrylate, methyl methacrylate, acrylic acid, vinyl chloride or vinyl acetate, or it may contain a graft copolymer of a mixture of styrene and acrylonitrile graft polymerized onto a rubber, e.g. polybutadiene or butadiene copolymer.  The shapable paste may be forced through holes under pressure while simultaneously exerting a wiping action on the paste as it enters the hole whereby the paste is shaped into bits of rod, e.g. of 1/100 -\ba1/4 inch diameter and lengths of 1/100 -\ba1/2 inch. The coagulant may be an acid, e.g. acetic, carbonic, sulphurous, sulphuric, oxalic or phosphonic acid, or may be alum or calcium chloride.  The pump may be a Moineau positive displacement pump.

Title: Improvements in or relating to carrier telephone systems
IPC: H04Q11/02
Filed: 1935-04-12
Abstract: 455,348. Carrier signalling. STANDARD TELEPHONES & CABLES, Ltd., 63, Aldwych, London.-(Assignees of Espenschied, L.) April 12, 1935, No. 24227/36. Convention date, May 26, 1934. Divided out of 455,279. [Class 40 (v)] In a high-frequency telephone intercommunication system in which each subscriber has an individual carrier-frequency which is used for both way communication in calls in which he is the called party, all carrier frequencies are supplied from a central station. A calling subscriber sets the dial HC to the position of the wanted party, thus tuning the selective circuits VF1, VF2 to the wanted party's carrier and simultaneously adjusting condenser VC for tuning the local oscillator VO so that the difference frequency produced in the modulator MO2 remains constant. He then removes his receiver, and RL3, energized over the hook switch, connects the combined modulator-demodulator MO1 to the selective circuits VF1, VF2. If the wanted party is busy ; his carrier will be received modulated at 60-cycles and the latter frequency, filtered out by LP and rectified at RF2, energizes RL4 to light a busy lamp BL and prevent interference with the existing call. Failing the operation of RL4, the wanted carrier is modulated at 1000-cycles when RL3 pulls up, and this frequency, selected by the filters FF4 or rectified at RF1, energizes the relays RL1 at both stations. At the calling station this results in the energization of RL2 which locks up and connects up the telephone instruments. At the wanted station, since the receiver is still on the hook, RL1 only rings the bell until the call is answered. It then energizes RL2 which, since RL3 is not energized at this end, modulates the carrier at 60 cycles as well as connecting up the telephone instruments. At the calling end the reception of this frequency energizes RL4 which cuts off the ringing control frequency. The circuits remain in this condition until the restoration of the receiver unlocks RL2, and, if necessary, RL3 at the station concerned. In the system shown, the carrier received from the central station is first combined with a local oscillation and the difference frequency, selected by a sharply selective filter, is amplified and again combined with the local oscillation. The resulting sum-product, which is of exactly the same frequency as the wave received from the central station but of greater amplitude, is used for modulation and demodulation. This apparatus may be omitted when the amplitude of the currents from the central station is sufficiently high initially.

Filed: 1963-06-18
Abstract: 980,942. Counting-apparatus. P. D. SCHWARZ. June 18, 1963, No. 24273/63. Heading G4D. A system responds to the passage of vehicles into or out of a parking area to adjust the indication of free spaces in the parking area. Passage of a vehicle over a coil set into the ground increases the flux density to de-energize a relay DR, Fig. 3, so operating a relay IR. Other detectors such as photo-electric, infra-red or ultrasonic may be mounted above or to one side of the passage way. The entrance has eight coils arranged in two groups C1-C4, C5-C8 spaced apart less than a car's length. A car entering the parking area affects one or a pair of adjacent coils first in one group and then in the other to energize 1FX and the 1RX, Fig. 2A, so as to operate magnet 15, which through a combination of differential mechanisms, Fig. 1, subtracts one from the indication at 14 of the number of free spaces. If two cars enter side by side two non- adjacent coils at least will be affected and 2FX operates followed by transfer relay TR. Relay 2RX energizes as the second row of coils is affected and magnet 2S subtracts two from the number of free spaces. Cars leaving affect exit coils EC9- EC12 and magnets 1AS or 2AS to add one or two as the case may be. If cars back out through the entrance they affect the add magnets 1AS or 2AS by operation of 1RX or 2RX before 1FX or 2FX. Interlocks are provided so that miscount is avoided if a car covers a coil and then reverses direction.

Filed: 1964-06-11
Abstract: 1,020,929. Measuring fluid flow. DEPUTY MINISTER OF THE RUMANIAN MINISTRY OF PETROLEUM AND CHEMICAL INDUSTRY. June 11, 1964 [June 11, 1963], No. 24310/64. Heading G1R. In a method of or apparatus for discharging and metering liquids from two groups A, B of oil and gas separators each group of which comprises a main separator 1 and an interconnected metering separator 2 the production from an oil well is led through a-line 14 to a pneumatically controlled three way valve 15 which directs the fluid to one or other of the two separator groups A, B, delivering the fluid to the separator 1 where the liquidgas separation is effected. The liquid flows through a pipe 6 to a metering separator 2 where it raises a float 3 which, on reaching a maximum level, actuates a lever 4 to move a slide valve 21 downwards to allow gas actuating diaphragm 10 of a pneumatic valve 7 to be moved to allow a valve 8 to be opened by a spring 11 and the liquid from the separators 1, 2 to be discharged and recorded by a counter (not shown). At the same time gas from a separator 1 is led through a filter 24, pressure reducer 25, line 27 and the check valve 28 to actuate the three way valve 15 to shut the inlet to the separator group B and to open the inlet to the separator group A. Gas, under pressure, also enters a line 29 and passes a check valve 30 to actuate valve 7 in the group A to keep valve 8 closed. The valve 8 is also acted upon by gas pressure through line 26. When the liquid level in group B drops to a minimum the float 3 operates a lower lever 4 to move the slide 21 upwards permitting gas under pressure to pass through line 26, to close valve 7, and through line 27 to the valve 15 which does not change its position since by closing check valve 28 by the pressure in line 29 the pressure in valve remains the same. The filling discharge cycle is identically repeated in separator group A and the three way valve 15 changes its position when the valve 7 opens owing to the removal of pressure in lines 26, 29 when these lines are placed in communication with the pipe 22 by the float 3 actuating the upper lever 4 of group A. An overflow signal device 5 is provided. A manual control 31 is also provided should a breakdown occur in one or other of separator groups A or B.
