Title: Multi-cellular aerofoil type parachute - has control lines controlling openings at rear of some of the cells
IPC: B64D17/02
Filed: 1974-04-24
Abstract: The aerofoil type parachute has an upper surface and a lower surface connected by walls forming cells which are open at the leading edge, and closed at the trailing edge. During a gliding descent, air is trapped in the cells under pressure to form a stationary air zone acting as a solid leading edge deflecting the air stream over the upper and over the lower surfaces of the canopy, as in an aeroplate wing. In addition to the usual suspension cords (9) control lines (11) are attached to the outside of the trailing edge, ending in handgrips within reach of the parachutist. The extra control lines control the openings at the rear of some of the cells, these openings providing a through a flow of air and greater control.

Title: Prevention of burning of polyurethane foam for seat upholstery - by preventing contact between foam and flames and entry of air into foam
IPC: D06N3/00
Filed: 1974-09-02
Abstract: Burning of polyurethane foam for seat upholstery is prevented by covering the outer surface of the foam completely or partially with a glass fabric with dense fibres, which may be directly adhered to the foam with any adhesive, which also seals the fabric and thus prevents entry of air into the foam. In tests where the glass fabric was previously torn, only the exposed portions of the foam were consumed, and the flames did not spread to the foam portions protected by the fabric. The adhesive also bonds the fibres together, increasing the wear resistance of the fabric.

Title: Open-weave shopping bags with bands of solid weave - which can be self-coloured and may receive a printed impression
IPC: D04B21/20
Filed: 1975-09-12
Abstract: The shopping bags are made with widely spaced rows of a chain stitch, linked across by occasional narrow threads. The weave is so open that distinctive colouring of the bag is not possible. Improvement is that the zone between two (not necessarily consecutive) chain rows is filled in so that becomes opaque and visible, whatever the bag is holding. This is done using a bulky thread for these rows, instead of the narrow one used for the rest of the bag; this thread being suitable for printing on. Alternatively, extra narrow threads are threaded through the present weave, parallel to the chain rows.

Title: Quick release safety belt coupling - has pivoting H-form bolt engaging strap tongue and engenders couple promoting release via secondary catch
IPC: A44B11/25
Filed: 1976-04-28
Abstract: The quick release safety belt coupling fastens the belt end to a pivoting anchorage block and includes a compensating mechanism which ensures a nominal release force whatever the traction through the coupling. In detail the coupling has an elongated tongue (P) which enters a socket in the anchorage unit to be retained by a basculing bolt (9, 10, 15). The bolt is of 'H' form in long section and rotates about a transverse axle (12) through the intersection of, say, the right hand leg and the bar (10). The inside basal face (14) of the left leg retains the strap tongue (P) and a laterally slidable bar (19) bears on the top (16) of this leg to form secondary retention. A traction force (F) through the coupling causes a couple which promotes release. This couple is resisted by the secondary retaining bar (9) which is slid away to effect release.
