Title: Improvements in or relating to vehicle steering mechanisms
Inventor: GOODACRE RONALD
IPC: B62D7/22
Filed: 1966-12-14
Abstract: 1,137,780. Vehicle steering mechanism. LANSING BAGNALL Ltd. 8 Dec., 1967 [14 Dec., 1966], No. 56059/66. Heading B7H. In steering mechanism for an industrial truck having a steering shaft 4 rotatable in a fixed tubular column member 5, a spring brake 6 associated with lost-motion connecting means between the shaft 4 and steering gear 1 is arranged to allow rotation of the shaft 4 for actuating the gear 1 but to prevent rotation of the shaft due to reverse actuation of the gear 1 caused by shocks exerted on the steerable wheel or wheels of the truck. A spigot 8 on the input member of the gear 1 carries a transverse pin 18 projecting into holes 9 in a collar 7 secured to the shaft 4, the holes 9 being larger than the pin 18 to permit limited lost-motion between the collar and the spigot. The brake 6 comprises a close-coil spring 10 which is closely fitted within a fixed housing 10 and has at mid-length a recess 22 engaged by a tag 12 on the pin 18, and near each end a recess 15, 16 engaged by a C-member 14 located in a groove 17 in the collar 7. When reverse actuation of the gear 1 tends to rotate the spigot 8 relative to the collar 6, one half of the spring 10 is expanded to grip the interior of the housing 3 and prevent such rotation.

Abstract: 1,186,310. Selective printing. STANDARD TELEPHONES & CABLES Ltd. 29 Nov., 1968, No. 56768/68. Heading B6F. [Also in Division G5] A magnetic recording head for electromagnetic printing and/or display apparatus comprises an insulating sheet 1 on which a plurality of wavy lines 2 of conducting material are formed, an array of holes 3 in rows and columns each row being associated with a wavy line 2 such that alternate holes in said row are located on opposite sides of the associated wavy line, the sheet 1 being folded concertina-wise along lines 13 so that the holes in each row are registered with one another coaxially and the wavy line forms a helical winding around the cylindrical hole so formed, a magnetic core member being passed through each such cylindrical hole and the assembly of core members and folded sheet being encapsulated in a body of non-magnetic material such that an end of each of the core members is flush with a recording surface of the body. The insulating sheet may be of thermoplastic material, and may be coated with conducting material such as copper, which is etched away to form the wavy lines 2. The holes may be formed by first etching the conductive material and then using the conductive material as a mask to etch the thermoplastic sheet. Alternatively, the holes may be punched, drilled or burnt, e.g. by a laser. The wavy lines may be printed on the sheet 1. The conductive wavy lines may be formed on both sides of the sheet or on one side only, in which case they may be coated with an insulating layer. The sheet 1 may be wider at its ends 4, 8, to provide more room for lead-in contacts and circuitry. The layer with end widenings may be formed from a rectangular sheet with a trapezium of material removed. The non-magnetic potting material may be epoxy resin. The cores may comprise straight rods (14), Fig. 2, not shown, which may be coupled to a further magnetic body (20), Fig. 4, not shown, or may comprise horseshoe shaped pieces (18), Fig. 3, not shown, the sheet 1 then being folded along alternate lines 13 only.

Patent GB-1366595-A (GB)
Title: Valve device for controlling operation of a brake cylinder
Inventor: HUBER J
IPC: B60T15/30
Filed: 1972-12-21
Abstract: 1366595 Relay valves; rail vehicle braking systems KNORR-BREMSE GmbH 21 Dec 1972 [28 Dec 1971] 59259/72 Heading F2F A railway vehicle compressed air braking system includes a valve device 2 for controlling the operation of a brake cylinder 40 in response to pressure changes in a main air line 5; the device 2 comprises a control piston 3 separating a control chamber 4 from an admission chamber 6 connected to the line 5, the piston 3 being connected by a rod 8 to a valve packing 9 of a bleed valve 9, 13 which controls admission of compressed air to a bleed chamber 11 and the packing 9 carries a valve tube 31 which is movable to actuate an inlet valve 42, 43 and an outlet valve 43, 46 to connect an auxiliary reservoir 44 to the brake cylinder 40 to give brake actuation. The valve packing 9 is disposed in a chamber 10 connected to the admission chamber 6 via a duct 110 and the valve seat 13 is formed on a control sleeve 12 having an interior duct 17 which includes a throttle 21. The sleeve 12 defines piston surfaces 15, 22 and is guided in the housing 1 with a small gap therebetween constituting a throttle passageway. A tappet 24 extends perpendicular to the sleeve 12 and is connected to an auxiliary piston 25 which separates two chambers 26, 27 connected respectively to bleed chamber 11 and to chamber 6: the piston is adapted to slide over a throttle duct 66. The valve tube 31 is secured to a piston 37 separating chambers 38, 39: chamber 38 is connected to atmosphere whilst chamber 39 is connected to brake cylinder 40 via a duct 39 and to a chamber 57 via a duct 56. Duct 39 is also connected to a chamber 48 separated by a piston 50 from a chamber 50 and piston 49 is actuable via a plunger 51 on a shut off valve 53 in a throttle duct 55 between chambers 4, 6. The chamber 57 is defined by a piston 58 which is actuable on a valve 60, to control connection of bleed chamber 11 to atmosphere via a duct 63 and a transmission chamber 62. Operation.-To brake the vehicle a pressure drop is introduced into line 5 whereupon piston 3 moves upwardly to open valve 9, 13, sleeve 12 being held in position by tappet 24. Compressed air then leaves the chamber 6 via duct 110, bleed valve 9, 13, duct 17, the passageway between sleeve 12 and housing 1, as well as bleed chamber 11 and also through the duct 28 into the chamber 26 and through the duct 63 into the chamber 62. The flow away of compressed air through valve 9, 13 allows piston 3 to be raised to an increased extent, and valves 42, 43, and 46, 43 are actuated to connect cylinder 40 to reservoir 44, and disconnect chamber 39 from atmosphere. Pressure in chamber 26 pushes piston 25 and tappet 24 rightwards so that sleeve 12 can move towards valve packing 9 just before pressure equilibrium is established between chambers 6, 11, valve 60 having been closed by pressure in chamber 57.

Patent GB-751148-A (GB)
Abstract: 751,148. Gyroscopic apparatus. SVENSKA AKTIEBOLAGET GASACCUMULATOR. April 12, 1954 (Oct. 26, 1953], No. 10679/54. Class 97 (3). An artificial horizon for use on aircraft comprises a spherical element cardanically supported so as to be freely movable for an unlimited number of revolutions about two mutually perpendicular horizontal axes, the spherical element being controlled through synchro devices by a separate gyro vertical to remain in a stable position relative to the earth, the artificial horizon being indicated by an equator on the sphere and a horizon bar arranged to move in front of the spherical element in opposite direction to the equator. As shown in Fig. 3 the spherical shell 10 is made in two parts screwed together and flattened at the ends, and has a central axle 11 journalled in mountings 21, 22 carried by a shaft 30, Fig. 1, rotatable in bearings in a wall 33 forming part of the instrument casing. The shell is controlled by a gyro-vertical by means of synchro devices, one having parts 16, 17 mounted respectively on a sleeve 27 carried by mounting 22 and surrounding axle 11, while the other has parts 38, 39 mounted respectively on shaft 30 and wall 33. Current foi the synchro devices is fed through slip-rings 40, 41 on shaft 30, and sliprings 24 on shaft 11. The sphere is coloured red and blue above and below the equator respectively ; in addition the polar regions may be coloured black and white. An aircraft silhouette is mounted on the front glass 36 to facilitate reading. Since the line of division of the colours sinks when the aircraft is diving, an additional horizon bar 50, which rises during a dive in the usual way, may be pivoted to mounting 21, 22 about an axis 51 offset from the axis of axle 11. Pins 54, 55 eccentrically mounted on discs 56, 57 on the ends of shaft 11 engage slots 53 in the bar 50. The movements of the sphere and bar are equal and opposite for shallow dives and climbs, and the indication is therefore doubled. The width of bar 50 may be such that a suitable angle of approach for landing the aircraft is obtained when the lower edge of bar 50 coincides with the upper edge of the silhouette 65. The artificial horizon may be mounted in the same panel as a compass, a rate-of-turn indicator, and lamps for indicating the correct functioning of the instruments.
