Title: Electronic timing mechanism
IPC: G04G19/10
Filed: 1983-04-13
Abstract: The present invention relates to an electronic timing mechanism having a pulsed voltage generator, frequency divider and binary counter, as well as a supply voltage source. It is the object of the invention to provide an electronic timing mechanism in which, after failure of the supplying voltage source, it can be determined upon the return of the supply voltage whether the time value stored in the timing mechanism before failure is still present and if that is not possible to cause the timing mechanism to run to a defined time setting. The object is achieved when the supply voltage input of the binary counter is bridged by a capacitor, and the input is applied to an input of a comparator whose other input is supplied from a reference voltage source. The main field of application of the invention is recharging control units for electric storage devices.

Title: wallboard or floor plate with a lattice carrier
Inventor: LANSINK ALFONS OUDE
IPC: E04F15/02
Filed: 1992-08-25
Abstract: In the case of a wall or floor slab (1) which exhibits a load-bearing member (3) having a surface (5) for receiving tiles (2) and, on the rear side, projections (6), the invention proposes to produce the load-bearing member (3) from a mesh material. In this way, either a very lightweight tiled slab can be produced or, by filling the cavities, a particularly stable and pressure-resistant tiled slab can be provided. Vibratory bedding-down of such tiled slabs into an aligned layer such as, for example, a screed ensures, as a result of the mesh material, an intimate bonding of the tiled slab with the underlying surface. <IMAGE>

Title: Energy-absorbing panel
Inventor: KERMAN MICHAEL L
IPC: F16F9/30
Filed: 1994-02-11
Abstract: An energy absorbing panel comprising a resilient polyurethane foam core having a density in the range of from about 1.5 to about 24 pounds per cubic foot and an indentation force deflection at 25 %, when measured pursuant to ASTM 3574-B1, less than about 4000 pounds and at least one energy absorbing surface comprised of a flexible reinforcing layer covering the resilient polyurethane foam core. The panel is useful in a variety of applications where energy management is required. Upon impact, the panel is capable of absorbing at about 70 % of the input energy. Further, upon compressor of the panel at the energy absorbing surface to about 50 % by volume of the uncompressed panel in a direction substantially normal to the reinforcing layer, the panel recovers to at least about 90 % of the volume of the uncompressed panel in less than about 30 minutes. The panel is particularly advantageous for use in vehicular applications such as door panels, instrument panel topper pads, air bag doors and the like.
