Title: Locking devices
IPC: B60R25/021
Filed: 1971-04-15
Abstract: 1381866 Anti-theft devices WILMOTBREEDEN Ltd 30 March 1972 [15 April 1971] 10657/71 Heading B7J [Also in Division E2] A vehicle anti-theft device has a locking slide 4 and bolt 5 within a housing 1 and movable together between operative and inoperative positions by an operating shaft 11 and cam 12, 13 acting on the slide and adapted to be turned by a key-operated lock mechanism, the bolt being of a non-circular cross-section and projecting from the housing in the operative position. The bolt and slide each have a sliding fit in the housing and are separably joined for relative orientation, on assembly of the device, about the axis of sliding movement of the bolt to permit the said sliding fits. As shown, the slide 4 is provided with a yoke 20 engaged in a necked portion 21 of the bolt 5 and is biased by springs 9 towards the locking position wherein the bolt engages and prevents rotation of a motor vehicle steering column. The lock mechanism in the housing part 2 is coupled by the shaft 11 to switch mechanism 7 connectible in the vehicle ignition and starter circuits. A key is inserted in the lock mechanism and turned in a direction to the electrically "off" position of the switch 7 and the shaft 11 is moved axially with the plug of the mechanism to advance cam sections 12, 13 into engagement with a cam follower surface 14 on the slide 4 and to depress a spring-loaded plunger 15; rotation of the shaft causes the cam section 12 to retract the slide and bolt so that the surface 14 rides on the part-cylindrical cam surface 13 coaxial with the shaft, whereafter the device may be further operated to switching positions for ignition and starting purposes. By turning the key back to the electrically "off" position and beyond that position the cam sections 12, 13 are carried clear of the slide but the plunger 15 engages a further cylindrical surface on the shaft 11 so that the slide remains retracted; withdrawal of the key allows axial movement of the shaft with the plug of the lock mechanism so that the shaft disengages from the plunger and the latter with the slide moves to the locking position. Electrical contacts may be included and operative in a circuit providing a warning if the vehicle driver leaves the vehicle without removing the key.

IPC: F16F9/19
Filed: 1928-04-11
Abstract: 303,486. Soc. Internationale Holverta. Jan. 5, 1928, [Convention date]. Fluid-friction vibration-dampers; arrangements of springs with mountings complete in themselves. -In vehicle suspension arrangements in which helical springs are disposed between the piston and one end of a cylinder which is nearly filled with liquid, the transfer passage between the pressure chambers on opposite sides of the piston includes a valve controlled by springs in such a way that sudden movement of the piston moves the valve towards but not into contact with one or other of two seats so as to reduce the effective area of the transfer passage. Two such devices arranged on opposite sides of the vehicle may be so connected to the steering gear that the damping action is modified differentially when running round curves in the road. The piston f, Fig. 1, is connected by a ball joint g to the vehicle frame h and the cylinder a is connected to the axle by a similar ball joint b. Helical springs i, i<1>, i<2>, of different lengths. adapted to come into action successively, support the weight of the vehicle. A limit spring i<3> is provided and a lighter spring may be arranged above the piston. The compression chambers above and below the piston f are connected by an outside pipe and a valve box k shown also in section in Fig. 3. The valve l is held floating between two seats l<1>, l<2> by springs n, n' encircling the valve guide stems l<3>. Adjustable screwed caps m limit the motion of the valve in either direction and prevent it from making contact with either seat. The resistance to flow of liquid may thus be different in the two directions. In the modified valve construction shown in Fig. 5, leaf springs n, n<1>, position the valve l between its two seats l<1>, l<2> and in addition a spring q may give it a bias more or less strongly towards the seat l<2>, the abutment for this spring being formed by a screwed spindle a with one operating lever p. The levers p on two suspension devices on opposite sides of the vehicle are connected to the steering gear so that the fluid-frictional resistance to deflection of the springs on the outside of a curve is increased.

Abstract: 1,060,425. Photographic printing apparatus. GRETAG A. G. March 13, 1964 [March 13, 1963], No.10806/64. Heading G2A. A photographic printing apparatus has a series of components defining the optical reproducing system, each component being selectable from a plurality of different components of the same kind, the series being selectable in accordance with the size of positive and negative chosen, and an electrical circuit whereby the component selected is compared with the component desired, and, if it is different, a safety device is actuated. In the form shown, light from source 1 passes first through a condenser lens. Two such lenses 3a, 3b, are carried on a disc 3, so that either can be rotated into the light path. The light beam then passes through one of three differently sized negative holders 4a, 4b, 4c, on a disc 4, and one of three objectives 5a, 5b, 5c having different focal lengths, any of which can be rotated into the light path. The positive print is made on a strip 7 of light-sensitive material, in front of which is a masking disc 6 having three differently sized apertures 6a, 6b, 6c, thus giving a choice of three finished print sizes. On each of the disc shafts 8a, 9a, 10a, 11a are respective switch boxes 8, 9, 10, 11, all connected with a main control and comparator box 13. With the arrangement shown, three different enlargement sizes are available, and the one selected is registered by pressing the appropriate switch 14. If the various components on discs 3, 4, &c. have been incorrectly set for this particular enlargement, a signal lamp is lit, and a safety device prevents the printing step from being carried out. The electrical circuitry for effecting this control is set out in more detail in Figs. 2 and 3 (not shown), and may also include servomotors for automatically correcting any error.
