Title: Measuring antenna mirror surface shape - using distance and angle measurement arrangement and computer separation gravitation independent and dependent deformations
Inventor: MIURA KORYO
IPC: G01R31/00
Filed: 1992-03-11
Abstract: The arrangement for measuring the shape of the mirror surface of a reflecting mirror antenna (1) contains a distance and angle measurement arrangement. A positioning device (7) carrying the measurement antenna rotates the antenna about its main lobe and stops at a defined rotation angle. The shape of the mirror surface is measured at a number of different rotation angles. A computer (9) performs an arithmetic operation w.r.t. the measured values and separates the shape of the mirror surface independent of the rotation angles from the angle-dependent deformation of the mirror surface. USE/ADVANTAGE - The arrangement enables separate measurement of the intrinsic mirror surface deformation under gravity-free conditions and the deformation as a result of gravity for an antenna attached to a satellite.

Title: Vehicle semi-trailer, e.g. for transporting boat or camping equipment - has brakes controlled by thrust on trailer king-pin measured by resistance strain gauges
Inventor: MAIER KLAUS
IPC: B60T7/20
Filed: 1992-04-10
Abstract: A semi-trailer has at least one axle and brakes for its wheels. Under an extension at the front is a kingpin which fits into the carrying saddle of the tractor.

There are buffers to limit this movement. A rod extends from the plate to a cylinder fixed behind it to the extension and which contains a strong spring. ADVANTAGE- Self-braking semi-trailer needing no direct connection to tractor's braking system.

Patent DE-4314460-A1 (DE)
Title: Arrangement for damping the pendulum motion of the load of a crane, in particular a container crane
Inventor: POSSELT THOMAS
IPC: B66C13/06
Filed: 1993-05-03
Abstract: Known pendulum damping arrangements with four damping ropes run obliquely downwards from the trolley to the spreader bar are technically of very complicated construction in order to also obtain effective pendulum damping at extreme amplitudes of pendulum swing and in the case of a low load. This especially applies to the guidance of the damping ropes via deflection and return pulleys and mechanisms for avoiding slack-rope formation. The novel arrangement is intended to reduce this complexity and create favourable rolling conditions at a rope inclination varying with the lifting and lowering of the load. Each of the damping ropes (5, 6) is run from a rope drum (4) via a deflection pulley (7) down at an angle to the diagonally opposite corner of the load-suspension means (8). The deflection pulley (7) can be swivelled in two planes via joints by a split lever. While it automatically adapts itself to the varying inclination of the rope guidance, the force preventing slack-rope formation is produced by a spring element. The arrangement enables effective pendulum damping with exact guidance of the damping ropes to be achieved solely via the deflection pulley machine element. <IMAGE>
