Patent GB-2281508-A (GB)
Title: Foldable wall type seat or table
Inventor: MASTERTON JOHN FRASER CRUX
IPC: A47B5/04
Filed: 1993-08-10
Abstract: A foldable support for a table or seat is designed to be secured to a vertical surface such as a wall or the front of a bar, and to fold flat against the surface when not in use. To this end, the support comprises an upper support strut 30 for supporting the table or seat, this strut having one end pivotally connected to the surface via a bracket. The other end of the upper support strut is pivotally connected to a pair of telescopically and pivotally interconnected support struts 36, 38, which when telescoped together form a rigid bracing member whose lower end is pivotally connected to the surface or the floor. When the upper support strut is lifted, the telescopically interconnected struts move longitudinally apart to a point where they can pivot with respect to each other, enabling the table or seat to be folded flat against the surface. The telescoping is via a pin and slot connection 52, 54, and the strut is locked via a locking tongue 56. <IMAGE>

Patent GB-2272504-A (GB)
Title: Flashback arrestor
Inventor: JENKINS TREVOR THOMAS
IPC: A62C4/02
Filed: 1993-11-04
Abstract: In a flashback arrestor unit for welding equipment or the like, a heat-sensitive valve, through which gas is supplied and which operates in the event of substantial or prolonged overheating of the equipment, comprises a permanent magnet (44) and a valve closure (38, 34, 36) of magnetically susceptible material acted upon by a spring (40) which is normally overcome by the force of attraction of the magnet on the valve closure, thereby to keep the valve open. In the event of overheating which causes the valve closure to lose magnetic susceptibility, the spring (40) is free to urge the valve closure against a valve seat in order to close the valve and shut off the gas supply. The valve closure may be formed by two discs (34, 38) and an intervening spaces (36). An aperture (46) in the disc (34) provides a controlled relief of the pressure differential across the disc, thus delaying reopening of the valve, following cooling of the unit. <IMAGE>
