Title: Superpolyesters
IPC: H01B3/42
Filed: 1961-05-05
Abstract: Linear fibre-forming polyesters with an intrinsic viscosity of at least 0.5 contain radicals of isophthalic acid together with p-phenylene, and/or mono- and/or di-chloro-p-phenylene radicals. The products are prepared as described in Specification 984,524, using as reaction solvent, benzophenone, m-terphenyl, chlorinated or brominated biphenyls or chlorinated or brominated diphenyl oxides. The acid halide may be condensed with the phenol, or the ester-interchange process may be employed.  Suitable phenolic reagents are hydroquinone, mono- or 2,3-, 2,5-, or 2,6-di-chlorohydroquinone. Chain-stopping agents, e.g. monohydric phenols or monobasic acid chlorides may be included in the reaction mixture if desired, or when free hydroxyl groups are desired in the product excess hydroquinone or resorcinol may act as chain-stoppers. A number of different examples are given illustrating the use of various solvent media, of different phenols and the two main methods of reaction.  The products may be used for fibres, films (which may be transparent), coating, impregnating, electrical insulation, laminating, or as adhesives.  Conventional additives may be added to compositions containing the polymers.  Specifications 984,161, 984,521 and 984,522 also are referred to.

Title: Improvements in or relating to vehicle parking meters
IPC: G07F17/24
Filed: 1937-06-15
Abstract: 499,307. Time-alarm signals; vehicle-parking meters. VEHICULAR PARKING, Ltd. June 15, 1937, No. 16612. Convention date, Nov. 24, 1936. [Class 118 (ii)] [Also in Groups XVIII and XIX] A parking meter is provided with an indicator which is caused to appear when the predetermined time has elapsed since the meter was set in operation. Upon a coin being inserted in slot 7, Fig. 6, and a handle rotated, a clockwork mechanism drives a pointer 42 over a time scale 10, and when the normal parking time has elapsed, a scale 52 is released to cover scale 10, The scales are of different colour and one may be painted with luminous paint. The pointer 42 continues to indicate time on scale 52 until it is reset, or reaches its limit of travel. Behind the front plate 8, Fig. 6, a member 18, attached to the spindle carrying the handle, normally lies behind slot 7 so that upon a coin being inserted, a resetting member attached by springs to the member 18, is displaced, thereby allowing a spring-urged pawl 18, to co-operate with teeth 27 on a track 26. The coin rides up the slope 29 to the track and, upon the handle being rotated through half a revolution, falls into a shoot where it is held from falling into the coin box by the projection 71 on the arm 69 and the member 73. Mounted on the back plate 16 is an arm 39 supporting a spindle 38, which carries the tune-indicating pointer 42 having its other end 41 urged clockwise by a spring 43. The scale 52 is carried by an arm 51 urged clockwise by a spring 54 attached to the other end 55 of the arm 51. A third lever arm 60 is urged anticlockwise by the strong spring 61 and may be held by the latch 62. Assume the meter is in the condition shown in Fig. 7, the pointer 42 having reached the end of its travel, and a coin is inserted in slot 7. As soon as the handle is rotated, the cover 22 moves to prevent another coin being inserted the lever 76 of a counter is actuated and the lug 72 strikes the cam-shaped, element 68, displacing lever 69 to release the coin in the shoot and moving arm 63 to free the latch 62, so that if the previous normal parking time has not elapsed, and the scale 52 is in its upper position, the arm 60 will rotate and due to engagement with lug 65, will cause the arm 51 to be brought to the lower position, the end 55 being engaged by the latch 56. Lug 32 engages the arm 41, returning it to the zero position, and lug 33 engages arm 60, rotating it until it engages the latch 62, Fig. 8. The coin now clrops from the member 18, the handle being returned by spring 20, the lug 32 touching the cam member as it returns to its normal position, thus freeing arm 51 which is rotated by spring 54 into the upper position, Fig. 9. The clockwork mechanism, carried behind the back plate 16, moves the pointer 42 over scale 10 until the end 41 engages the adjustable stop 66, whereupon the arm 63 pivots, releasing arm 60 which causes the scale 52 to move to its lower position.

Title: Improvements in or relating to coin-operated mechanisms
Inventor: ROGERS WILLIAM GEORGE
IPC: G07F5/02
Filed: 1952-07-02
Abstract: 723,579. Coin-freed mechanisms. SELFSERVE AUTOMATIC MACHINE CO., Ltd. July 1, 1953 [July 2, 1952], No. 16627/52. Class 27. The drawer 4 of a vending machine is normally held closed by the engagement of a leaf spring 9 carried by it with a projection or projections 12 on a coin shoot 6 and when a coin 8 is inserted through a slot 5 it rolls down the shoot until arrested by the leaf spring so that, on pulling the drawer open by means of a handle 14, the coin, rolling slightly backwards, raises the spring clear of the projections until it engages the upper edges 15 of the shoot and is raised further to release the coin into the coin box 1. The projections 12 are preferably of saw-tooth form so that the spring slides over them as the drawer is shut but prevents fraudulent opening of the drawer before it is completely shut. According to the Provisional Specification, the leaf spring may be replaced by a pivoted lever loaded either by a coil spring round its pivot or by a spring arranged between it and a fixed part of the mechanism.

Abstract: 1,118,702. Moulding powdered material. F. MALKIN & CO. Ltd. 15 April, 1966 [20 April, 1965], No. 16667/65. Heading B5A. [Also in Division B8] In the forming of workpieces from powdered material, e.g. circular, oval, square, oblong, flat or curved shapes, by pressing between an upper die and a lower die which lower die may be stationary or hydraulically or pneumatically displaceable, the powdered material, e.g. clay dust, is deposited within the lower die, e.g. a saucer die, through a sheet or wire gauze sieve, at the base of a hopper, which is vibrated, e.g. by suspension from an electromechanical vibratory device, the material in the filled die being consolidated by contact with the sieve. The cross-sectional contour of the die and sieve may be identical or may be relatively varied, e.g. to provide a lighter clay deposit towards the periphery of the saucer, the amount of clay deposited in the die being determined by the spacing of the sieve therefrom. The feed of material to the hopper at the same station at which vibration is imparted can be pre-set by an electronic, mechanical or fluid pressure timing device. Either the sieve or the die may be moved to enable the pressing operation to be effected by an upper die which operation may be preceded by a light tamping action effected by repeated strokes of the lower die in relation to the sieve.

IPC: H01Q1/10
Filed: 1975-04-23
Abstract: 1481928 Vehicle antenna NEW-TRONICS CORP 23 April 1975 16913/75 Heading H4A An extendible and retractable vehicle antenna comprises a rod 14, a track 30 mountable beneath and parallel with a vehicle panel 12, a rider 32 reciprocable along said track with means 56 on the rider for pivotally receiving the inner end of rod 14, antenna rod guide means 26, e.g. a ball, mountable on the panel 12 and rotatable about an axis perpendicular to a diametrical bore (86, Fig. 3, not shown) provided for the rod 14, and a bracket assembly 36, 38 for mounting the track 30 beneath panel 12. As described rider 32 is internally screw threaded to co-operate with a threaded shaft 66 within track 30, said shaft being driven by a reversible motor 64. Mounting plate 36 is connected with bracket 38 by a pivot pin 46 and a nut and bolt 50 in an arcuate groove 48 so that the track, mounted on said plate 36, can be set up vertically beneath the guide means 16 so that the antenna, when extended, is vertical. A conductive spring 60, having a channel 62 for the fully extended antenna, conducts the received signals through an inductor 61 to the receiver. The inductance 61 is so chosen that the combination of antenna and inductance resonates at the centre of the received band (stated to be 98À0 MHz for f.m. reception). The guide means 16 comprises a spherical ball (Fig. 3) preferably of nylon, having a diametrical bore to slidably receive the antenna, the ball being retained in a part-spherical recess between two nylon plates (Figs. 3-5) which are secured to the vehicle panel. In an alternative embodiment (Figs. 6, 7, not shown) the motor is unidirectional and the shaft is reverse threaded so that the rider may travel in either direction during one direction of rotation of the shaft. The rider of this embodiment is therefore provided with a follower (138) to engage the threads of the shaft, the follower being mounted on a pin (140, Fig. 7) which may rotate in a recess (142) in the rider. In both embodiments the rider has two grooves which receive the edges of respective tracks 30, and prevent rotation of the rider. It is also possible to eliminate the motor and threaded shaft and extend and retract the aerial manually. Alternatively the rider could be driven by a pulley and chain. Switches 84, operable by the rider 32, are provided to switch off the motor 64 when the antenna is fully extended or retracted, there being a two-position switch within the driver's compartment to start the motor in either direction. In the second embodiment the motor is operated by momentary depression of a push switch which is biased open by a spring. A circuit is described which maintains the operation of the motor after release of the switch until the rider opens a switch at one end of the track.

Abstract: 819,607. Fuel injectors. SAURER Ltd., A. May 28, 1957 [July 19, 1956], No. 16942/57. Class 7(3) In an injection nozzle having an outwardly opening valve 9 loaded by a spring 10 abutting against a spring retainer 11, a disc valve 13 loaded by a subsidiary spring 14 seats on an annular seat 23 on the spring retainer and has a small clearance S between its outer edge and the bore of a sleeve 15 in the nozzle and a larger clearance 19 between its inner edge and the part of the spring retainer 11 passing . therethrough, the flow of the fuel during delivery causing the valve 13 to lift and pass through the space 19 in addition to the initial flow through the space S. The spring retainer comprises a nut 11 abutting the spring 10 and a lock nut 16 carrying the seat 23 and provided with guide fins 17 which are a sliding fit in the bore of sleeve 15 and guide the upper end of the valve stem. At the beginning of the delivery stroke fuel can only pass through the small clearance S which produces a small fuel injection and a pressure build-up which suddenly forces the valve 13 off its seat 23 allowing comparatively free flow of fuel through the larger passage 19. The surface of the nut 11 co-operating with the valve 13 may be tapered inwardly so that the passage 19 increases as the valve moves further away from its seat.
