Abstract: A three-dimensional textile (3) formed from two sheets of textile (5, 6) placed face to face and connected together by a plurality of extensible threads (10) is impregnated with resin and inserted between two layers (16, 17) so as to form a layered structure (1). This layered structure (1) is inserted between two dies (25, 26) of a heated press which is subsequently closed to allow the resin impregnating the structure to distribute itself uniformly. The layers (16, 17) are then attached by vacuum to the faces of the dies (25, 26) which are then opened through a first controlled distance within the limit of the elastic recovery of the three-dimensional textile (3). The outermost layers of the structure (1) are then polymerised by heating of the dies (25, 26) while the resin impregnating the threads (10) remains in a plastic state. The lower die (25) is then released in the plane in which it lies and the dies (25, 26) are then moved apart through a second distance so as to stretch the threads of the three-dimensional textile and align them substantially vertically; the floating die (25, 26) is then locked. The dies (25, 26) are then moved away from each other to a predetermined distance to extend the threads (10) completely and the press (28) is kept in this position until all the resin has polymerised completely, the structure hardening in the position assumed.

Title: Power supply
Inventor: ROSENDAHL GLENN
IPC: H02J3/10
Filed: 1994-02-15
Abstract: A microprocessor controlled system is provided for supplying electrical power to a plurality of electrical outlets for example for use in a parking lot. A central power supply communicates with a series of outlet receptacles each arranged to supply electrical power. Each receptacle has its own microprocessor controlled control unit which is arranged to control the supply of power to the receptacle. A detector unit detects the insertion of a connector plug to the receptacle and actuates a comparator which compares the instantaneous current drawn by the load with a predetermined variable maximum current and allows that current to be drawn only if it is less than the maximum. In the event that the maximum is exceeded, the load is disconnected and is only allowed to be reconnected after the connector plug is removed. A thermostat can be used to control the supply of power depending upon the outside temperature. The microprocessors can select a part only of a cycle for supplying power so that the total power drawn by the central power supply is reduced.
