Title: Improvements in suspensions for perambulators, for invalids' vehicles, vehicle seats, and the like
IPC: B62B9/18
Filed: 1934-08-10
Abstract: 424,813. Suspended seats; spring mountings. LARROUZE, L. J., 107, Rue de Marseille, Lyons, France. Aug. 10, 1934, No. 23180. [Class 52 (ii)] [See also Group XXXII] The body of a perambulator or a vehicle seat or the like is suspended from its supporting members by means comprising one or more wholly or partially elastic cables, each of which passes over a pulley disposed in a vertical plane and mounted either on the support or on the supported body. In the construction shown in Fig. 2, which is typical of numerous modifications, the body 2 of a perambulator is suspended from the longitudinal members 8 that connect the axles by means of elastic elements 3 which are attached at their ends a, c to the supports 8 and body 2 respectively and pass over pulleys 5 mounted on the body. Either by adjustment of the pulleys 5 in relation to the points a, c or by adjustment of one or both of the points a, c, e.g. on an arc c<1>, c<2> as indicated, the vertical displacement of the body under a particular load can be varied to requirements. Other constructions are described in which the pulleys are mounted on the supports, and one or both ends of the cables are connected to the body, or the pulleys may be mounted on the body and both ends of each cable to the supports. In another arrangement, Fig. 4, the ends of two cables are united at their inner ends c, and their outer ends are connected to the wheel axles 11 which are formed as extensions of cranked rods 12, the pulleys 5 being mounted on the body. In the application to a vehicle seat, Fig. 12, (not shown), suitable guides and guide rollers are provided to permit only a vertical movement of the seat. For the purpose of adjusting the position of the pulleys, or one or both ends of the cables, straight or curved slotted guides, Figs. 23, 27, 28, (not shown) may be employed. Or, in place of adjusting the end a, an adjustable slide 22, Fig. 25, moving in a slot 24 may be provided, the displacement of the cable as the load varies then taking place about the point d.

Title: Improvements in or relating to sintered uranium-plutonium compounds
Inventor: PASCARD ROGER
IPC: C01B31/30
Filed: 1963-06-11
Abstract: 1,034,505. Nuclear fuel. COMMISSARIAT A L'ENERGIE ATOMIQUE. June 11, 1963 [June 20, 1962], No. 23261/63. Heading G6C. Nuclear fuels containing uranium and 15 to 80% by weight of plutonium are prepared by grinding a U/Pu alloy of the desired Pu content in an inert atmosphere to produce a pulverulent product which is then compressed and sintered either after mixing with another metal or solid non-metallic element, or substance, or after heating in an atmosphere comprising nitrogen or hydrogen sulphide. The other metal may be Mo, Mb, Ta, or Zr and the non-metallic element may be carbon or silicon. The reaction may be achieved in one stage, i.e. the U/Pu alloy and any additional solid material are ground directly together, or in two stages when the U/Pu alloy is ground in an inert atmosphere and then the additional material is introduced, the final step in either case being heating, compressing and sintering. In examples, mixed carbides and nitrides are formed.

Title: Improvements in change speed gear for motor vehicles
IPC: F16H3/16
Filed: 1931-08-18
Abstract: 392,894. Change-speed gearing. BELATI, U., 56, Via Pier Carlo Boggio, Turin, Italy. Aug. 18, 1931, No. 23290. Convention date, March 18. Void [Published under Sect. 91 of the Acts]. [Class 80 (ii).] Change-speed gearing for vehicles of the countershaft type has constant-mesh pairs of helical gears 6, 22 and 23, 9 and 24, 34 with the teeth sloping so as to balance end thrusts. The slope of the teeth on the gear 6 fast on the driving-shaft 2 is in the same direction as that of the driven gears 9, 34 loose on the driven shaft 4. The slope of the gears 22, 23, 24 all last on the countershaft 5 is in the same direction opposed to the teeth of the other gears. The amount of slope of the teeth of the pair 9, 23 is calculated to obtain perfect balance on the highest reduced speed. In driving, the shafts 2, 4 are thrust towards one another and a ball thrust bearing 37 is set between their ends acted on by a spring 38 in a hollow in the shaft 4. Direct drive and next speed are obtained by sliding a clutch ring 11 splined on the shaft 4 into engagement alternatively at 7 and 8. Lower speeds are effected by sliding a splined .spur gear 21 alternatively into clutch engagement at 35 and into gear mesh at 25.

Title: Improvements in slidable window mechanisms
Inventor: KENLOCK ALBERT ALEXANDER HOBAR
IPC: E05F11/38
Filed: 1951-10-10
Abstract: 707,095. Windows. VAUXHALL MOTORS, Ltd. Sept. 9, 1952 [Oct. 10, 1951], No. 23545/51. Class 20 (3) A slidable window mechanism includes resilient means which is stressed as the window frame is moved from and beyond a normal open position towards a limit position with its edge flush with a fixed frame and which is strong enough to return the window freely to normal position. A motor vehicle window 10 shown in normal open position is supported by balancing mechanism including an arm 11 pivoted at a point 12 and connected at its end remote from the window to the end of a tension spring 14 attached at its other end to a fixed part 26. An abutment 15 on the arm in this window position just makes contact with the spring so that pressure on the window edge to lower it to the limit position causes a deformation of the spring sufficient to return the window to normal position. The window may be maintained at the lowermost position by engagement with the upper surface of the window finger piece 16 of a spring-urged pivoted catch 17 ; depression of a button 21 rocks the catch to release the window which rises to normal open position. In another embodiment abutment 15 is omitted and the lower edge of the arm depresses a compression spring carried on a fixed part. An alternative retaining catch comprises an arm with a pivotal axis normal to the plane of the window and a projecting cam contacted by the finger piece as the window is pushed down to rock the arm against the pull of a spring which retracts the cam over the top edge of the finger piece in the limit position of the window. A serrated top portion of the arm provides for manual retraction to release the window.

Title: Combination torsion bar-hinge pin for an enclosure having a lid
IPC: A45C13/00
Filed: 1965-06-02
Abstract: 1,073,689. Spring hinges; latches. DOMINION ELECTROHOME INDUSTRIES Ltd. June 2, 1965 [June 17, 1964], No. 23608/65. Headings E2A and E2F. An enclosure (e.g. a "hi-fi" cabinet) includes a lid hinged to the enclosure at an open end thereof, by means of a pair of hinges having a common torsion bar hinge pin 24, and a latch for holding the lid in a closed position, the latch being released by depressing the lid towards the enclosure and the torsion bar 24 biasing the lid to an open position. The torsion bar hinge pin 24 has bent ends 26 engaged in openings in the lid and a 'U' shaped bend at the centre of its length indirectly and adjustably fixed to the enclosure, a plate 32 engaging the 'U' bend and a screw 29 passing through plate 32 and being screw threaded into a plate 28 on the enclosure. Adjustment of screw 29 permits adjustment of the torsion in the bar 24. The Latch (Fig. 3) includes a spring loaded catch plate 42 movable along and across, by rotation about point 43, a slot 37 in latch housing 36 affixed to the inside-front of the enclosure. On closing the lid, a finger (55) thereon (not shown) contacts the surface 48 of plate 42, moving plate 42 sideways to permit finger (55) to meet surface 52. On releasing the closing force, finger (55) rises, allowing plate 42 to rotate under the action of its spring until finger (55) is trapped under projection 47 of the plate 42. To open the lid, it is depressed until finger (55) lies below the level of an inclined finger 50, the plate 42 then rotating further until finger (55) abuts the left hand side of opening 49. The lid is then free to open, plate 42 being pushed aside across slot 37 as finger (55) rises up inclined finger 50.

Title: Improvements in beam-deflecting means for cathode ray tubes
IPC: H04N3/185
Filed: 1946-08-09
Abstract: 623,037. Supply systems for cathode-ray tubes; converting. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 9, 1946, No. 23609. Convention date, Aug. 9, 1945. [Classes 38 (ii) and 38 (iv)] [Also in Groups XL (a) and XL (b)] The deflecting means of a cathode-ray tube is coupled to the source of anode potential in such a way that variation of the latter affects the former so that the image master retains its size and shape. In Fig. 2, the output of valve 12 is fed to the transformer 18 whose secondary winding 34 is connected to the line deflection coils 16; a damper tube 20 is connected across the secondary as described in U.S.A. Specification 2,309,672. The primary winding is provided with a stepped-up portion 28 which is fed to a surge type high-voltage rectifier 30. This may be a single rectifier or may include means for increasing the voltage as in Specification 613,053. This rectifier supplies the anode voltage of the cathode-ray tube; any excess load on the tube therefore loads transformer 18 and thus reduces the output from the secondary 34. By suitable design it can be arranged that a reduction in anode voltage thus decreases the current in deflection coils 16 so that the length of the lines remains constant. This circuit only corrects for line distortion; the vertical length of the fixture will remain distorted. In Fig. 4 both horizontal and vertical deflections are compensated. An output is taken across the high resistance 36 from rectifier 30 and used to control the vertical sweep circuit. In another arrangement, Fig. 6 (not shown), a circuit is described which is suitable for use when the H.T. supply is a separate force back instead of being derived from the deflection voltages. Specification 434,199, [Group XL], also is referred to.
