Patent GB-2080762-A (GB)
Title: Retractable chock arrangement for a vehicle lifting ramp
IPC: B66F7/28
Filed: 1981-05-05
Abstract: Upon raising of track member 10 of the ramp, lever 18 swings anticlockwise about pivot 17 and causes peg 22 to engage thrust surface 25 of a J- shaped slot in block 23, thereby to raise flap 15 which then will prevent a vehicle (not shown) supported on the ramp, from rolling off the track member. Reaction of the peg 22 with the bottom of the slot retains the flap 15 in its raised position and prevents it being swung up further. Upon ramp lowering, the lever 18 is swung clockwise, by roller 21 engaging the ground, to permit the flap 15 to lower under its own weight, and eventually disengages the peg 22 from the slot. <IMAGE>

Title: Reflectors
Inventor: WISOTZKI JURGEN
IPC: G02B5/08
Filed: 1983-07-19
Abstract: A reflector made of copper, silver or gold, is formed by the surface of a single crystal. This surface can be polished. The surface can either be the (100)-orientation surface or, alternatively, the (111)-orientation surface of a copper single crystal, which has been etch-textured. In this condition, etch-pits 12 are exhibited by the crystallites forming the surface, each of these etch-pits individually forming a small concave mirror. The reflectors with etched surfaces scatter incident radiation and tolerate higher laser outputs than reflectors with polished surfaces. In order to protect comparatively large areas on satellites and rockets from laser beams, it is possible to position several single-crystal reflectors side-by-side, in contact with one another. The reflector surface can be plane or curved. <IMAGE>

Title: Vehicle differential gear housing supporting apparatus
Inventor: IIJIMA YOSHITAKA
IPC: F16F1/52
Filed: 1983-11-22
Abstract: The differential gear housing (1) is connected to the vehicle body through at least one first elastic member (26) which deforms in shear mode when the housing (1) vibrates up or down or back and forth to the vehicle body (2,3) and additionally through at least one second elastic member (27) which deforms in both shear and compression modes when the housing (1) vibrates up and down and in only shear mode when the housing (1) vibrates back and forth. Since the deformation mode of the second elastic member (27) changes from shear mode to compression mode gradually with increasing displacement of the member, it is possible to obtain a desirable elastic modulus such that the elastic members are soft when vibrations are small but hard when vibrations are strong, without any points of discontinuity. <IMAGE>
