Title: Cushioning material and method of producing the same
Inventor: FOX HERBERT AUSTIN
IPC: B29C70/42
Filed: 1958-12-29
Abstract: 903,143. Laminates. L.O.F. GLASS FIBERS CO. Dec. 29, 1958, No. 41832/58. Class 140. [Also in Groups V, XIV and XXXII] A laminated cushioning material is made from a layer or layers of glass fibres, bonded by a cured synthetic resin, and one or more layers of similar fibres impregnated with an uncured thermosetting resin such as a phenol-, urea-, or melamine-formaldehyde resin, the uncured layer or layers being brought into contact with and bonded to the cured layers with a pressure which increases the density of the former layers during the curing of the contained resin. The initial density of the uncured may be substantially higher than that of the cured layers. The material as described, has inner cured layers which are resilient and outer, initially uncured, layers forming a hard skin. Such material is stated to absorb shocks without rebound and to be usable as, or for making, crash pads, moulded upholstery, insulation parts and platforms for boxing rings &c. The glass fibres used may be formed with an average diameter of about 5 microns, by a high-temperature, high pressure blast which simultaneously coats them with resins, those fibres to be used initially cured being passed directly to a curing oven and subsequently compressed to the desired degree. The laminates may have outer layers of decorative material such as polyvinyl chloride or fabric. A motor car crash pad is made by laying glass fibre mat 28, Fig. 7, impregnated with uncured thermosetting resin in a stainless steel or other mould 29, superimposing a resilient pad 30 of similar mat containing cured resin and a second layer 31 similar to the layer 28, and pressing the whole, while heating, with the male member 32 of the mould. The pad 23, Fig. 2, with decorative fabric facing layers 18, 19, is secured along one edge as by screws 21 to the dash-panel and along the opposite edge to the windshield moulding strip 15, the layers 18, 19, being separated and clamped by a block 20. The strip 15 is adjustable by a screw 17 engaging the body work 16 to tension the pad. The initially cured part c of the pad is shock-absorbing without rebound, and the parts d, a, f initially uncured, are hard and resistant to compression.

Abstract: 1,171,234. Spray producers. H. SUNDERLAND. 15 Oct., 1968 [13 Sept., 1967], No. 41836/67. Heading B2F. [Also in Division B5] A gun for spraying a mixture of sand and resin and a medium for curing or fusing the resin comprises an inlet 13 for resin coated sand leading via a flared passage 19 into a nozzle 18 and an inlet 15 for heated air which serves to propel the sand-resin mixture and fuse the resin. The air passage is split into two portions, the first of which leads via passages 24 and annular space 26 to outlet 25 and the second of which leads via passage 22 to chamber 23, from which it passes through louvres 27 into the resin coated sand stream, thereby heating and fusing the resin. In a second embodiment (Fig. 3) sand is blown by a cold air stream along tube 31 and through the space between spindle 33 and the walls of chamber 32. The spindle 33 is fitted with vanes 34 which mix the sand with resin from inlet 35 and catalyst from inlet 37. Air (which may be heated) supplied through inlet 39 acts as propellant and spray former for the sand-resin mix.

Means for securing a sleeve 19 to a shaft having a sleeve bearing portion 12, with a radially toothed end 14, comprises a collar 18 operatively connected to a radially toothed member 25 such that relative rotation of the member 25 and the shaft prevents axial movement of the collar, and a further member 28 which locks the member 25 against rotation relative to the shaft. The collar 18 is taperbored to receive a tapered ring 22 keyed to the collar and having internal threads engaged by the threaded periphery of the internallytoothed member 25. The internal teeth of the member 25 pass over corresponding teeth 14 of the shaft to a groove 16 such that relative rotation of the member 25 to the shaft 12 to the limit determined by a stop 17 prevents axial movement of the member 25 and collar 18. An internally-toothed flanged locking member engages with the teeth 14 of the shaft and the teeth of the member 25 to prevent rotation of the latter, the locking member being clamped against a resilient ring 32, abutting the member 25, by a circlip 33. Axial clamping movement of the collar 18 is provided by the screw threads and the engaging tapered surfaces. The teeth on the member 25 may be weaker than those on the shaft to break under excess axial load. Specification 956,551 is referred to.

Polymers used are homo- or copolymers of styrene, nuclear and or side chain-substituted styrenes such as α- methyl styrene and vinyl toluenes, lower alkyl methacrylates, vinyl chloride and vinyl esters. Stabilizers, plasticizers, lubricants and fillers may be used. In preparing the original body, heat plasticized polymers may be rolled or kneaded, powders may be dry blended whilst solutions of polymers may be mixed directly and the solvents evaporated off. In moulding the composite body, extrusion, injection, compression and transfer techniques may be used; fibres may be spun.

A leak-proof pump for spraying liquids or dispensing pastes comprises a pumping chamber 7 mounted in the neck 1 of a container, and a bucket piston 5 connected by a discharge stem 17 to an actuating button 10, e.g. having a spray nozzle 2, a cylindrical portion 6 of the pumping chamber acting to close the discharge groove 21 and port 3 in the piston 5 during an initial part of the discharge stroke, so that, when groove 21 and port 3 are opened, the pressure in the pumping chamber has built up sufficiently to ensure a satisfactory spray without dribbling. Expansion of the pumping chamber volume to permit the initial part of the discharge stroke is provided for by an elastic wall portion 7, as shown, or by forming a flexible part of the pumping chamber as a partly flattened cylinder or sphere which expands to form a true cylinder or sphere on increase in pressure, or by forming the lower part of the pumping chamber with latural or longitudinal folds, Figs. 7, 8, 12 and 13 (not shown). In Fig.9 (not shown), a dip tube of flexible material has the inlet valve at its inlet end, and is formed with partly flattened walls which expand during the inital part of the discharge stroke. In Fig. 4 (not shown), the pumping chamber has a uniform cylindrical bore, the distension of the pumping chamber wall, during the initial part of the discharge stroke, acting to uncover the discharge groove and port. In Fig. 5 (not shown), spaced longitudinal grooves in the pumping chamber wall act to uncover the discharge groove and port at spaced intervals during the discharge stroke, to provide discharge of predetermined duration at predetermined intervals. In this embodiment, a vent port communicating with the container interior is closed, when the piston is in its uppermost position, by a conical portion of the discharge stem engaging a complementary bore in the container closure carrying the pump, the vent port being open during the discharge stroke. A return spring 11 may be provided around the discharge stem, as shown, or may act between the bottom of the piston and the inlet end of the cylinder, thereby biasing the cylinder walls against the piston to improve sealing. In the embodiment shown, container vent port 16 is uncovered by the piston during the discharge stroke. The pumping chamber may be formed integrally with the container closure, as shown, or may be separate, Figs.3 to 5 (not shown). The closure may be screwed or crimped on to the container. The piston and stem may be an integral moulding, as shown, or may be made of metal with separate sealing elements Fig.6 (not shown). Liquid in the nozzle is returned to the pumping chamber during the inital part of the suction stroke to prevent drip.
