Title: Improvements in or relating to toy vehicles
Inventor: RASSIER CECIL ARTHUR
IPC: A63H29/18
Filed: 1955-02-10
Abstract: 765,142. Mechanical toy vehicles. SEBEL & CO., Ltd., D. Feb. 10, 1955, No. 3972/55. Addition to 682,060. Class 132(3). The rack member of the toy vehicle transmission mechanism of the parent Specification is reciprocated by a Bowden cable connecting the rack member with a manually operable remote control device. A wire 19 of a bowden cable 20 has one end secured at 24 to a rack 11 and is secured at its other end 25 to one member 26 of a pair of remote control grip members pivoted together scissor-fashion, Fig. 3. The rack is normally urged forwardly by a rubber band 15 tensioned between a slot 17 in the rack and a pin 16 provided on the base 1 of the vehicle, but upon closing the grips 27 of the remote control device, the rack is drawn rearwardly by the wire 19. Release of the grips permits the rack to be drawn forwardly again, and by alternate closing and releasing of the grips a reciprocating movement is imparted to the rack 11. The vehicle may be steered by means of a wheel 59 having an arm 58 secured to one end of a further Bowden wire 57 which at its other end is connected to a pivoted bracket 49. Front wheel supports 40 are linked by a rod 45 and are normally biased in an anticlockwise direction as seen in Fig. 2 by a spring 54, a lever 52 and a link 51. Rotation of the steering wheel in a clockwire direction rocks the bracket 49 anticlockwise and a main steering link 46 is moved forwardly thus rotating the wheel supports 40 clockwise against the tension of the spring 54. Fig. 4 shows a modification whereby a separate steering control is dispensed with. The rack is made longer and has flanges 64, 65 for engagement with rollers 72 of levers 66, 67 which have arms 70, 71 spring loaded towards the sides of the rack 11a, slotted portions 73 of the arms engaging with steering links 74 connected to the wheel supports 40. By reciprocating the rack 11a over its middle portion the vehicle is propelled along a straight path but by reciprocating the rack over one of its end portions the lever 66 or 67 is continuously engaged by the corresponding flange, the vehicle then being propelled and at the same time steered in one direction or the other. In both steering constructions provision is made for causing a dummy driver to lean in the direction in which the vehicle is steered.

Title: Improvements in or relating to pressure-operated striker devices
Inventor: MAISEY HAROLD ROBERTS
IPC: F16K17/40
Filed: 1955-02-11
Abstract: 807,191. Pressure-relieving devices for fluids. GRAVINER MANUFACTURING CO. Ltd., and WILKINSON SWORD Ltd. May 11, 1955 [Feb. 11, 1954], No. 4018/54. Class 135. A striker mechanism comprises a striker biased for movement into an operative position, a slidable catch which embraces part of the striker and is biased so that normally it holds the striker in its non-operative position, and pressure-sensitive means which, on the application of a predetermined pressure to it, acts on the catch to move it against its bias and so releases the striker. In an embodiment, excess pressure of the fluid in a vessel is relieved when a frangible disc 9 is shattered by a striker pin 17a, the latter being normally held in the retracted position by a slidable catch 13 but being projected towards the disc 9 when the catch is slid out of engagement with the pin by the expansion of a bellows 11 subject to the pressure in the vessel. The pin slides in a sleeve 16 and balls 18 carried in apertures in the sleeve are, in the position shown, forced by bars carried by the slide 13 into a groove 17b on the pin so that the latter is locked to the sleeve. When the bellows expands, it moves the slide 13 against its loading spring 14 until the balls can move out of the grooves 17b and into recesses in the bars carried by the slide. This frees the pin 17 which is then projected towards disc 9 by a spring 19. The latter is protected by a bellows 23. A screw cap 15 allows of adjustment of the biasing force provided by spring 14. Disc 9 is pre-stressed to facilitate its destruction by securing it by means of clamps 22 between a sealing-ring 20 and pegs 21. Specifications 568,055 and 786,872 are referred to.

Title: Dielectric materials
IPC: D04H13/00
Filed: 1972-12-20
Abstract: 1378935 Laminates IMPERIAL CHEMICAL INDUSTRIES Ltd 20 Dec 1972 [1 Feb 1972] 4704/72 Heading B5N [Also in Divisions, B2 and H1] A dielectric spacer comprises a thermoplastic polymeric film and, on one or both surfaces thereof, a thermoplastic polymeric fibrous layer in the form of a melt-spun non-woven textile. Both the film and fibrous layer may be of polysulphone, polycarbonate, polyhexamethylene adipamide, polycaprolactam, polyethylene terephthalate, polyethylene-1,2-diphenoxyethane- 4,4<SP>1</SP>-dicarboxylate, polypropylene or propyleneethylene copolymer. The film may be produced by melt extrusion as a tube and subsequently biaxially oriented. It may be metallized with aluminium, zinc, silver, gold or nickel and the fibrous layer is then applied to the metallized or unmetallized surface by melt-spinning thermoplastic fibre from a multiorifice spinneret and randomly depositing the fibre in the molten state upon the moving film. The spacer is used in the production of capacitors either by winding together spacers and conductive electrodes in the form of separate metal foils or by depositing the electrode as a metallized coating on the film (see above). The capacitor may be impregnated with a dielectric fluid, especially trichlorodiphenyl (others specified). The spacers may also be used for cable insulation by lapping the conductive members of electrically conducting cables and in the production of an electrical bushing in the form of a cylindrical sleeve fabricated from a number of superposed layers of the spacer. In the example, a capacitor is formed by cutting two strips from a spacer made by melt-spinning polypropylene fibres on to polypropylene film, winding the strips alternately with two strips of aluminium foil, heating the assembly under reduced pressure to 120‹ C. and impregnating the assembly by immersion in trichlorodiphenyl.

Abstract: 683,187. A.C. generators charging batteries. KRUPP ELEKTROWERKSTATTEN, F. March 2, 1951 [March 6, 1950], No. 5093/51. Classes 35 and 38 (iv). The exciting winding 8 of an A.C. generator feeding a battery 5 and a variable load 6 through a rectifier 2, is also energized from the A.C. output through a rectifier 9 and is controlled by a saturable reactor 12 (only one phase of which is shown) preventing overcharging of the battery. The reactor carries a pair of opposed saturating coils 13, 14 connected in parallel across the battery, the excitation of coil 13 depending on the battery voltage while coil 14 is connected in series with a barretter 15 which maintains its excitation current constant irrespective of battery voltage. The coils are proportioned so that when the battery voltage rises at the end of the charging period the effects of the coils balance leaving the reactor 12 unsaturated, thus cutting off the excitation current in the coil 8. The generator also carries series excitation windings 10, 11 arranged to carry the generator output current and the load current respectively. These windings are so proportioned that the charging current can be made independent of the load current.

Title: Improvements in and relating to telegraphic systems
IPC: H04L13/10
Filed: 1929-02-16
Abstract: 307,827. Ateliers J. Carpentier. March 14, 1928, [Convention date]. No Patent granted (Sealing fee not paid]. Type-printing telegraphs; synchronous movements.- In a line or wireless telegraph system in which electro-optical transmitters are used in connection with the Baudot or a similar code, synchronization is effected bv means of a starting impulse which precedes the code impulses. Transmitter, Fig. 1. A tape A is perforated with a starting hole e0 for each horizontal or oblique group of code holes e1 - - e5, and moves between a group of light sensitive cells E0 - - E5 and a mirror M1 which reflects light from a source L1 on to the cells. When the cell E0 is energized by the light pencil which reaches it through a hole cO. it sends an impulse to line and also causes the mirror M1 to swing through a small arc. The light pencil thus passes through one or more of the holes el - - e5 in succession so as to energize corresponding cells, which thereupon cause impulses to be sent to line. Receivers, Fig. 2. Incoming impulses control the brightness of a lamp L2, or the movement of a screen associated with the lamp, and the first impulse acts through light-sensitive cell E<1>0 and an amplifier to swing the mirror M2 through an arc. Succeeding impulses are thus reflected on to cells E<1>1 - - E<1>5 in succession and cause one or more of the magnets S1 - - S5 to record the signals for subsequent retransmission at a lower speed. Modifications. The cells E1 - - E5 or E<1>1 - - E<1>5 may be replaced by a single cell on to which the light pencil is reflected by a set of five mirrors. the fluctuating light source L2 may be replaced by a constant light source combined with a lightvalve. Several parallel tapes A and several receivers may be served by one pair of mirrors M1, M2. Synchronous movements. - The oscillation period of the receiver mirror M2 is approximately equal to the period t1 of the transmitter mirror M1. To allow for slight differences, the lightsensitive cells E<1>0 - - E'5 at the receiver may be made longer, Fig. 3, than those, EO - - E5 at the transmitter. Thus the ratio of the two periods may vary between t<1>2 : t1 and t<11>2 : t1.
