Title: Systems for the orientation of vehicle headlamps
IPC: B60Q1/068
Filed: 1971-07-08
Abstract: 1352211 Adjustable headlamps P CIBIE 8 July 1971 [27 July 1970] 32036/71 Heading F4R  A system for adjusting the attitude of vehicle headlamps comprises a camming device 20 which has a central pivot engaging an aperture in a vehicle body 12, a lever 28 on one side of the pivot for rotating the device, and on the other side of the pivot a plate 25 in the form of a sector of a circle on which are a number of flat raised faces 26b separated by inclined faces 27 so that as the device is rotated this screw point rides over the inclined faces to rest on a flat face to give various attitudes to the headlamp. The sector of a circle has an included angle of 30 degrees and the movement of the lever is limited by stops 13. The screw point is pressed on to the camming device by a spring.

Title: Improvements in or relating to masking devices for rooflights
IPC: E04D13/03
Filed: 1938-11-07
Abstract: 520,979. Shutters for rooflights. EBERSPACHER, P., and EBERSPACHER, A., [trading as EBERSPACHER, J.]. Nov. 7, 1938, No. 32168. Convention date, Nov. 6, 1937. [Class 20 (iii)] A masking device for rooflights comprises flaps 25 each of which is mounted on a shaft 6 having rollers 8 which are guided on horizontal 'rails 10 lying within the angle of the roof In the construction shown in Fig. 6, the movement of the flap to and from its closing position is effected by means of a rope which passes around a pulley secured to one end of the shaft 6. The flap is carried by a telescopic rod one part 27 of which is secured to the flap and the other part 28 pivots about a belt 29 disposed beneath the rails 10. In a modification, the rod consists of one part only, is pivoted at a point above the rails, and is slidably mounted in guides which are adjustably secured to the masking flap. In order to ensure that the flap shall completely mask the window aperture, means are provided to prevent the shaft 6 for assuming an oblique position when the flap is in the operative position. As shown in Fig. 10, the shaft 6, at that end remote from the pulley, is fitted with a roller 7 and a sleeve 39, which are secured to the shaft, and an intermediate loosely-mounted flange 38. This flange is adapted to ride up an inclined surface 40 of a member 41 fitted to a rail adjacent to the rooflight. When the flange 38 rides up the inclined surface, the load on the roller adjacent thereto diminishes and the roller begins to slide on the rail 10, whereas the roller secured to the other end of the shaft continues its rolling movement until it reaches its limiting position.

IPC: F41B7/00
Filed: 1952-12-19
Abstract: 709,259. Toy cannons. BRITAINS, Ltd. Dec. 19, 1952, No. 32314/52. Addition to 617,492. Class 132(3) The toy cannon and cartridge element described in the parent Specification is modified in that a striker R comprises a plunger 1 having a tail 7 and nosepiece 10, the shoulder of the nosepiece, when the shell case S is primed, engaging the sides of an opening 6 in a cup-shaped insert 5. A breech block 14, pivoted on a pin 17 and capable of being loaded by an arm 18, is provided with a firing pin 12 which is normally urged in a withdrawn position by a spring 30 and which has a recess 11 corresponding to the nosepiece 10. Operation of a firing lever 32, 33 causes firing pin 12 to be urged forwardly by a stud 34, the plunger 1 being centralized by the engagement of the nose 10 in the recess 11, and the tail 7 moving clear of the opening 6 thus allowing the plunger 1 to move forward under the action of a spring 15. The cartridge is automatically ejected when the breech block 14 is opened to reload, an arm 27 attached to the block swinging in a slot 28 and engaging a flange 4 on the shell case. The cannon is supported on a carriage having forward and trail bogies and, to prepare the cannon for firing, the forward bogie is moved from its travelling position to a position where the wheels W are clear of the ground on which a platform 41 then rests directly. The trail bogie mounted for steering in grooves 68 in arms 43, Fig. 5, is then disengaged from the arms by removal of a transverse member 44 and the arms are moved to a position shown in chain-dotted line. The barrel B is movable axially and is locked in either the travelling or firing position by means of a catch, Fig. 7 (not shown). Worm operated elevating gear E causes the barrel to pivot on trunnions T, and traverse is provided by a table 40 rotatably carried on the ground platform 41.

Title: Improvements in or relating to electric motor control systems
IPC: B60L7/04
Filed: 1954-11-19
Abstract: 748,120. Control of D.C. motors. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Nov. 19, 1954 [Dec. 7, 1953], No. 33563/54. Class 38(3) Relates to a series-parallel control system for an even number of series-wound motors, for example traction motors, which are adapted to be over-driven by the load to act as generators. In the arrangement shown, a first motoring position of a master controlled provides a connection with armatures 1-6, field windings F1-F6, and accelerating resistors R1, R2, R3, in a series circuit between the supplyline and earth. In this connection, and in all the subsequent connections, the accelerating resistors are on the highpotential side of the armatures and the field windings are on the earth side, so that the insulation requirements of the motor field windings are reduced. Further movement of the controller reduces the accelerating resistance, introduces field shunting, and provides the transition circuits for a series-parallel grouping of the motors. In this grouping, the resistors R1, R2, R3, are connected in parallel with each other and in series with a first motor circuit comprising armatures 1, 2, 3 and field windings F1, F2, F3. A second motor circuit is connected in parallel with the first and comprises the. remaining motor armatures and field windings. After reduction of the acceleration resistances, the final series-parallel grouping is attained in which three parallel circuits each comprise two series-connected motors. The accelerating resistors are again connected in parallel with each other between the supply-line and the motor circuits. To introduce dynamic braking operation, the 'master controller is moved backwardly, from the "off" position to the first braking-position whereby the line and powerearth connections are interrupted. The braking-connectios has three parallel-connected branches, the first branch comprising resistor R1, motor armatures 1, 2, 3, and field windings F4, F5, F6, of the other motors. The second branch comprises resistors R2, and the third branch armatures 4, 5, 6, and field windings F1, F2, F3. A terminal A2' is held at earth potential due to a high-resistance connection 73 to earth, and, since the motor voltages are all substantially equal, a corresponding point A6<SP>1</SP> is also near earth potential. This arrangement again reduces the earth-insulation requirements of the motor field windings. In the remaining braking operation controller-positions, the resistors R1, R2, R3, are cut out in suitable steps, the operative portions of the resistors R1, R3, being kept equal in order to maintain a balanced dynamic braking circuit.
