Patent GB-1132661-A (GB)
Title: Disc brake assemblies
IPC: F16D55/224
Filed: 1967-02-02
Abstract: 1,132,661. Disc brakes. GENERAL MOTORS CORP. 2 Feb., 1967 [14 Feb., 1966], No. 5123/67. Heading F2E. In a disc brake having primary and secondary brake actuators, the secondary brake actuator comprises coaxial first and second helically interconnected rotary members 40, 48, Fig. 2, having a frictional drive connection 80 therebetween, a helically-surfaced cam and follower arrangement 70, 72 between the first rotary member and the brake caliper and a ratchet and pawl arrangement 58, 60 between the second rotary member and the brake caliper. Rotary brake-applying movement of the first rotary member rotates the second rotary member whilst rotation in the opposite direction initially rotates the second rotary member until lost motion in the ratchet and pawl assembly is taken up and thereafter differential rotation of the first and second rotary members adjust the brakes. Movement of lever 66 anticlockwise (in Fig. 1, not shown) causes the bushing 40 to move towards the brake pad 30 because of the interaction of face cams 70 and cam followers 72. The face cams 70 are the same hand but of greater pitch than screw-threads 44 and rod 48 is rotated in the same direction by a frictional drive plug 80 without any relative axial movement between rod 48 and bushing 40, thus causing the brake pad 30 to engage the brake disc 12. The floating caliper arrangement causes the opposite brake shoe 32 to engage the disc. During this movement the spring pawl 60 permits rotation of the ratchet wheel 58 but during clockwise movement in the brakedisengaging direction the spring pawl only permits rotation of the wheel 52 until the next tooth 64 is engaged whereupon further rotation of the wheel 58 and rod 48 is prevented. The drive plug 80 slips and rod 48 is screwed out of bushing 40 towards the brake pad but, owing to the greater pitch of face-cam 70, the rod still undergoes an overall axial retraction movement. During subsequent applications there is no relative movement between the rod 48 and the bushing 46 until the angular motion of the bushing again exceeds the angular pitch of the ratchet teeth 64. If the adjustment provided is insufficient to give full brake engagement a repetitive operation permits the ratchet assembly to take up the extra clearance. The cam and follower arrangement may be replaced by large-pitch threads, splines or cam tracks.

Title: Improvements in and relating to seats for vehicles
Inventor: SIMONS ALLISON KENT
IPC: B60N2/54
Filed: 1963-02-08
Abstract: 1,070,381. Vehicle seats. BOSTROM CORPORATION. Feb. 4, 1964 [Feb. 8, 1963; July 2, 1963], Nos. 5124/63 and 26286/63. Headings A4J and A4U. A vehicle seat 11 is resiliently mounted on a base part 10 by means of a suspension member 12 which has one end pivoted to the seat 11 and the other end to the base 10, through a torsion bar assembly. The seat back support 11b Fig. 1, is interconnected with a hollow upright portion 10b of the base by rollers 26 which are attached to the back support 11b and movable in the hollow upright portion 10b. Alternatively a pivoted linkage may interconnect the back support and the upright portion to guide the seat, which linkage may be vertically adjustable on a slider moving in the upright. The torsion bar assembly 13 comprises a bearing sleeve 15 fixed to the base 10 and a torsion bar 16 housed within, and attached to the outer ends of a pair of telescoped tubes 17. The load on the torsion bar 16 and hence the upward force applied to the suspension member 12 is varied by rotating one tube relative to the other. This may be effected by rotating a screw 22 upon which is mounted a loading arm 20 secured to the inner end of one tube 17. A shock absorber 30 is mounted within the upright portion 10b having a piston rod 31 connected to the back support 11b. Another seat 41, Fig. 4, is mounted on arms 43 pivotally connected to a base 40 through a torsion bar assembly. The permissible stroke of the seat 41 may be defined by the outer end of a lever arm 61, which is connected to the torsion bar, moving over an arc, between limiting stops 62. By varying the position of these stops 62 the height of the seat is adjusted. Alternatively the upper end of a flexible strap 70 may be secured to the seat 41 or one of the arms 43, and its lower end secured to an adjustable screw 71 so that rotation of the screw 71 adjusts the maximum elevation of the seat. Also an adjustable parallelogram system of links may be connected between the arms 43 and seat 41 to adjust the height of the seat. The seat 41 may be tilted to a vertical unused position shown in dotted lines, Fig. 4. A vibration damper 80 may be fitted within the upright 40b.

Title: Improvements in automatic tuning devices for wireless apparatus
IPC: H03J5/22
Filed: 1941-04-25
Abstract: 553,787. Tuning of wireless apparatus. GENERAL ELECTRIC CO., Ltd., and ROSE, W. R. April 25, 1941, No. 5343. [Class 40 (i)] Tuning mechanism for a wireless transmitter or receiver comprises mechanism for selecting one of a number of operating members corresponding to operation of a push-button or the like and operating mechanism which moves the selected member, the selection and operation each being performed by electromagnetically actuated pawl and ratchet mechanism. The arrangements by which the operating members set the tuning devices are described in Specification 553,786, [Group XXXVI]. The circuits are shown with push-button PD and relay H operated as the result of a previous operation. When another button is pushed, PD is released in known manner and H falls back to complete a self-stepping circuit for magnet 16 which rotates shaft 31 until the operating member 41 of spring set 28 drops into notch 32 of cam 27 in one of its two normal positions. The shaft also rotates discs 15 and pins 14 thereby releasing lever 13 of the lastoperated condenser setting mechanism (right hand set) which restores under spring action to the normal position occupied by the other sets. The spring set 28 opens the circuit of magnet 16 and closes an initial circuit for selecting magnet 3 over spring set 12 (normal). Shaft 2 is stepped and the driving circuit is maintained in a local circuit over spring set 12 (operated) until the next selecting position is reached. If this corresponds to the depressed button, H is operated to open the vertical driving circuit. One of four heart-shaped cams 8 on shaft 2 has thus turned lever 13 of one of the form link mechanisms into the path of an operating pin 14 and the operation of relay H completes the circuit of magnet 16 to drive shaft 31, until projection 30 on cam 27 operates spring set 28. The consequent rotation of pin 14 sets the selected link mechanism to the position shown for the right-hand set of mechanism. Lever 13 operates a toggle 21, 23 to move slide 19 and arm 20. Each slide and arm of the set of form, sets and locks the condenser in a predetermined position. The arm 20 operates through a cable and pulley. When the mechanism is to be dismounted for maintenance, key 30 is thrown to cause magnet 16 to drive shaft 31 into normal position in which the operating members are released.

Title: Improvements in and connected with clamps, vices, and other gripping or holding devices
IPC: B25B1/24
Filed: 1925-02-26
Abstract: 230,080. Joksch, R. March 1, 1924, [Convention date]. Clamps; vices. - The pressure of a gripping- device of the type having the gripping-face constituted by the ends of a number of separate slidable elements automatically adjusting themselves to fit any shape of work-piece, to be held is substantially equalized over all the gripping-elements by a transmitting medium such as plastic caoutchouc, viscous grease, small steel balls, or pulverulent material. The gripping-elements 2 are each formed with a slot 3 through which passes a bar 10 connected to a supporting block 9, the remaining parts of the slots being filled with the plastic or other transmitting medium 4, When pressure is applied by the screw 8, the reaction by the work on the gripping-elements first contacting therewith exerts pressure on the transmitting medium in the slots of those elements and forces it into the slots of adjoining elements so as to bring the latter into contact with the work. Each element has a projection 5 engaged by a pin 6 urged by a spring 7 tending to push it forward. In a modification, the gripping-elements are enclosed in a casing, and have upward extensions engaged by a spring-pressed transverse bar.

Title: Headlamp for a motor vehicle
IPC: F21S8/10
Filed: 1972-02-07
Abstract: 1380495 Vehicle lamps DUCELLIER & CIE 7 Feb 1972 [16 Feb 1971] 5478/72 Heading F4R A motor vehicle headlamp comprises a dipping filament 2 which is partly masked by a screen 1 wherein the inclination of the filament axis to the axis of the reflector 4 is adjustable and the orientation of the screen 1 with respect to the filament 2 is adjustable, so that, with an additional light reflecting, refracting or absorbing element 7, the pattern of light emission shown in Fig. 2 is obtained, where V-V is a vertical through -the reflector axis and L-L is a horizontal. As shown in Figs. 7 and 8 the element 7 is a section of a paraboloidal mirror 11 fitted adjacent the centre of reflector. Alternatively, if a part of reflector 4 is made transparent, a mirror 7 may be disposed outside the lamp enclosure, or the mirror 7 may be formed by directly deforming the reflector 4. As a further alternative the element may be formed by an absorbent non-reflective zone on the reflector comprising black paint or cutting the reflector itself. A still further alternative, Figs. 9 and 10 (not shown), form of the element comprises a dioptric element (8) which forms a part of front glass 6 of the lamp. In effecting the adjustment, the lamp is first inclined at an angle # to the axis X-X of the reflector and then the lamp is rotated about the filament axis an angle # to form a completely horizontal cut-off boundary, Fig. 4 (not shown). The provision of the element 7 adjacent the centre of the reflector then produces the cut-off boundary of Fig. 2.
