Abstract: 1280825 Joining roof or wall panels BRODERICK STRUCTURES Ltd 2 Oct 1969 [4 Oct 1968] 47227/68 Heading E1W A roofing or walling structure comprises panels formed of one or more slabs of backing material 2 with plastics or metal strips 5 secured to the panel faces at their edges with an upstanding flange having an inturned lip 7. Adjacent metal strips of adjacent panels form a structure with an inverted V-shaped cross-section over which a resilient channel like strip 8 is clipped to provide a sealed joint. The panels may be of particle board or plywood covered with metal foil protected roofing felt. Junctions of three panels are sealed by clipping over the joining channel like strips 8 a T-shaped finishing strip (13) Fig. 4 (not shown). In a similar way the junction of four panels is sealed by a cruciform finishing strip (10) Fig. 2 (not shown). Where the join of the panels occurs at a roof ridge the finishing strip 10 has opposite arms turned down at the ridge angle. The flashing construction at the roof edge comprises an L- or T-section strip (21, 18) Figs. 6 and 5 respectively (not shown) in place of the strips 5. Weather proofing material of felt or copper 3 is laid over the backing material 2. The strips 5, 8 and the finishing pieces may be of stainless steel, aluminium, copper or plastics.

Abstract: 1488799 Endless tract manifold system; compressors EXXON RESEARCH & ENG CO 18 Oct 1974 [22 Oct 1973] 49087/73 Headings F1B and FIN Cylinders in which pistons reciprocate, e.g. in I.C. engines or compressors, have inlet ports connected to an endless induction tract 11 in which fluid is caused to circulate in one direction only and which comprises means for promoting a pressure build-up in the tract near each inlet port when its associated piston is on its induction stroke. Charge enters tract 11 via a duct 12 and passes to inlet port 13b, pressure build-up being induced by tapering of the tract upstream of port 13b. A rotary valve (15) Fig. 2 (not shown) allows the charge to enter a cylinder (21) when the piston (20) is on its induction stroke. Alternatively, or in addition, pressure build-up may be promoted by a restriction such as a nozzle in the tract downstream of the inlet port, or by a tongue 16b connected to the valve diverting the charge into the inlet port. At the end of the induction stroke, valve (15) closes and tongue 16b moves to allow charge remaining in the tract to pass to the next cylinder through a Venturi 17b which converts the pressure energy of the charge into kinetic energy. A buffer space 18b is provided to inhibit the formation of reduced pressure waves travelling in the opposite direction to the charge flow.
