Title: Drive shaft for motor vehicle
Inventor: AMBORN PETER DR
IPC: F16C3/02
Filed: 1990-04-04
Abstract: The shaft comprises a tubular central portion (Rm) disposal between, and of larger outside diameter than, two end portions (13,14). It is axially asymmetric with the centre of symmetry of its central portion or its centre of gravity axially offset from the centre of the shaft. The cross-sectional area may thus be optimised and the natural frequency of vibration displaced to a value subject to minimum external excitation in use, to reduce noise. Surface formations may be provided on the shaft central portion or damping sleeves fitted to it.

Title: Storage unit for cylindrical workpieces - has spring-loaded opposed roller pairs forced apart by workpiece and locked in supporting position
Inventor: MARKWART EIKE
IPC: B25B1/20
Filed: 1990-04-11
Abstract: A pair of facing U-section columns (3) can move inwards or outwards in common T-slot guides in the baseplate (1). Each column has two rollers (4) on a bracket which can pivot about a central axis parallel to the work axis. A system of springs and interconnecting chain drives loads the two facing roller systems inwards so that work entering the unit contacts the rollers (4) and forces the columns apart. When the four rollers have opened to suit the work diameter and the roller axes have formed a rectangle, a locking bar (10) engages with the linking chain and prevents further movement of the columns. When the work is removed the unit returns to its starting position. USE/ADVANTAGE - Simple design with low wear and low mfr. cost.

Title: Control of vehicle seat lumbar support
Inventor: OGASAWARA HIROMITSU
IPC: B60N2/90
Filed: 1990-10-30
Abstract: A lumber support plate (22) is built into the back rest of a vehicle seat and a d.c. motor (12) is controlled to adjust the position to suit the user.

Title: Solar-powered domestic hot water system - has solar collector connected directly to hot water system and thermostats to control supply pump to use available heat, and to avoid overheating and frost damage
Inventor: MEUCHT BERNHARD
IPC: F24D19/10
Filed: 1991-04-19
Abstract: In a new method for using solar energy to produce domestic hot water, the solar collector is connected directly to the hot water supply system. A thermostat in the collector switches the supply pump on, and a thermostat in the pump inlet pipe switches it off. A system for protection against freezing switches the pump on when the temperature falls below a predetermined value. USE/ADVANTAGE - Used in solar-powered domestic hot water systems. The proposed system is simpler than indirect water heating systems (two separate storage tanks are not required), and uses only the hot water storage tank already present in most households. Can be easily and inexpensively integrated into existing hot water systems.

Title: Distorting component for motor vehicle - has tapering portion thrust inside beam which folds against it
Inventor: THUM HOLGER DIPL ING
IPC: B60R19/34
Filed: 1991-08-19
Abstract: The distorting component is particularly for a motor vehicle, and comprises a hollow beam (1) and a tubular distorting portion of smaller dismeter, supported from the beam by an external flange (3-5). Thus under a force of predetermined value on the lengthwise axis the component is shortened by thrusting the distorting portion inside the beam. This portion (2) tapers away from the beam, which distorts so as to form one or more folds (9) bearing against the distorting portion when this is thrust inside it. There can also be an external flange on the beam, joined to that of the distorting portion. ADVANTAGE - Largely absorbs kinetic energy, and also effective for a limited angle from the lengthwise axis.
