Title: A method of forming metallic honeycomb material
IPC: B21D47/00
Filed: 1966-03-15
Abstract: 1,130,527. Welding by pressure; making honeycomb structures. HEXCEL CORP. 15 March, 1966 [15 March, 1965], No. 11360/66. Headings B3A and B3R. Honeycomb material is formed by coating one face of a plurality of metal sheets or foils with broad parallel strips of a rubbery or plastic stop-weld material to define weld areas therebetween, forming the sheets into a stack with the stopweld material disposed so that the weld regions on either side of each sheet are staggered, directing an explosive shock wave into the stack to weld the sheets together in the weld areas and subsequently expanding the welded sheets to form the honeycomb material. The shock wave is applied to the stack of sheets by a flyer plate 26, having a layer 28 of explosive and an intermediate layer 27 of rubber, the plate being disposed originally at a small stand off distance 24 and angle A from the top of the stack 14. A discard plate may be laid on the top of the stack to prevent damage to the top sheet. To prevent tearing of the foils at the edges of the weld regions the stop-weld material is preferably positioned so that the edges of corresponding generally superposed weld regions lie in a plane offset from the vertical (Figs. 6, 7, not shown). To increase the number of sheets which may be welded the thickness of the stop-weld material is preferably increased towards the bottom of the stack (Fig. 8, not shown). A momentum trap, preferably consisting of similarly superposed sheets or foils may be arranged closely around the edges of the stack to be welded (Fig. 9, not shown), the momentum trap serving to reduce damage and tearing at the edges of the sheets. The flyer plate is preferably identical in size with the stack or, where a momentum trap surrounds the stack, with the outer peripheral size of the trap. A stack of sheets to be welded may be placed on top of and welded to a similar stack already explosively welded. Aluminium foils of thickness 0.0015 to 0.0025 inch are referred to as suitable. Poly. vinyl alcohol is referred to as a suitable stop-weld material and since it is soluble in water it may be removed easily after welding. It is preferably applied from a solution also containing sugar by means of a rotogravure roller. The minimum and optimum thicknesses of the stopweld material are given as 50 and 80 microinches respectively. In the examples explosive welding is described as taking place on a stack of sheets held in an evacuated rubber lined chamber. The stop-weld material may serve to hold the metal sheets together adhesively prior to welding.

Title: Viscose composition and method of spinning
IPC: D01F2/10
Filed: 1962-03-26
Abstract: Filamentary materials are made by spinning viscose containing from 1-5% of the cellulose of a polyoxyethylenated butynediol containing an average of from 4-20 moles of ethylene oxide per mole of 2-butyne-1,4-diol.  Desirably, the polyoxyethylenated butynediol contains 4, 6, 8, 10 or 20 moles ethylene oxide per mole of 2-butyne-1,4-diol.  Viscose may be used containing 6-10% cellulose with a caustic soda content of 4-8% and 30-50% carbon disulphide based on the weight of cellulose.  After addition of the polyoxyethylenated butynediol the viscose may show a salt point above 5, and preferably 7 or 8 at the time of spinning.  The coagulating bath may contain 7-10% sulphuric acid, 12-23% anhydrous sodium sulphate and 1-10% anhydrous zinc sulphate, and may be held at 45 DEG -70 DEG C., preferably at about 65 DEG C.  Filaments emerging from the coagulating bath may be passed through a hot aqueous bath either acid-free or containing about 10% by weight sulphuric acid and stretched 80-150%.  A third aqueous bath containing, e.g. 3% by weight sulphuric acid and 5% anhydrous sodium sulphate may be used to complete the regeneration. Filaments so made have a smooth non-crenulated exterior surface and consist entirely of skin.  They have a high tensile strength, superior abrasion and fatigue resistance characteristics and are suitable for tyre cord.  U.S.A. Specifications 1,970,578, 2,213,477, 2,575,832, 2,593,112 and 2,676,975 are referred to.

Title: A method for the manufacture of objects from thermoplastic artificial foam material and objects thus manufactured
IPC: B29C65/02
Filed: 1955-04-21
Abstract: <PICT:0806693/IV (a)/1> <PICT:0806693/IV (a)/2> <PICT:0806693/IV (a)/3> <PICT:0806693/IV (a)/4> Pieces of foamed polyurethane having one non-porous surface skin are formed into objects by sealing the edges of a single piece by fusion and compression or by joining one piece to other pieces of polyurethane at the edges by any method. The material with one closed surface is obtained when the top portion of a foamed layer of polyurethane is sliced off to leave a wholly porous layer of uniform thickness and yield the portion of irregular thickness with one irregular closed surface.  Irregularities of the closed surface may disappear if the material is stretched when the edges are sealed.  A great variety of articles which may be made by combination of a suitable number of suitably shaped pieces is listed in the Specification.  If a number of pieces are united to produce an object the whole outer surface of which is formed of the closed surface layer, air- and water-tight articles may be made.  In such articles the interposition of intermediate layers minimizes risks of leakage due to puncturing of closed outer layers.  Material between outer edges may be locally united to yield seams, which may have strengthening and decorative value. In examples: (1) a pad which may be used as a brush is formed by unifying by sealing the edges 3, Figs. 1, 2, of a piece of foamed polyurethane having a closed surface 1, porous portion 2 and porous surface 4.  A spanning band 37 may be attached with the welded edges and serves for holding the pad. Several pieces of material may be united in this way (see Fig. 6), by fastening their edges together to form similar objects which may have either porous or closed under-surfaces as well as a closed top surface. Such an object may be used for packing articles between the layers before the last portion of the edges is closed by sealing. Welded seams may also be provided across the middle portions of such objects, e.g. to form more compartments.  Fig. 7 shows a device for welding edges and cutting the welded material.  Other objects illustrated are a flower pot casing and a camp bed with attached head-rest.

Abstract: 864,529. Froth flotation. DUVAL SULPHUR & POTASH CO. April 9, 1957, No. 11526/57. Class 82(2) In a froth flotation process producing a middlings product, this product is mechanically separated into at least two fractions. The material to be treated (especially potassium chloride/sodium chloride and clay) is mixed with a collector and pumped into a first flotation cell A. The froth product (sodium chloride and clay) from this cell are fed to a second cell B and the sink from this cell treated as middlings. These middlings are fed to a vibrating screening device C, the coarsest particles being fed via line 35 into the surge tank 17 with the froth concentrate from cell B and the finest particles being fed (line 36) to the tailings (line 15) of cell A. The intermediate fraction is fed to the froth concentrate (line 37) but may be further worked if desired. The separaate potassium chloride is recovered by a centrifuge 18 and the liquor is recycled via line 20. This liquor is a saturated solution of the soluble ore components.

In a machine for loading pallets, comprising a vertically reciprocable platform 10 which carries a pallet 15 on a rollerway 13 and a horizontally movable table 3 carrying goods 14 to be loaded, the table 3 is raised by the pallet or goods 16 thereon which causes reversal in the direction of movement of the platform 10 through a predetermined distance and subsequent horizontal movement of the table 3 with transfer of the goods 14 from the table on to the pallet. In a cycle of operations the table is brought above the platform 10 where wheels 4 depress contacts 8 to close an electric circuit which causes platform 10 to be raised by chains 11. Subsequent upward displacement of table 3 releases one or more contacts 8, whereupon platform 10 is lowered to a position giving a slight clearance, e.g. a few millimetres, between the pallet or goods thereon and the underside of table 3. With lowering of the platform all contacts 8 are again depressed and the table is withdrawn, a stop (not shown) being positioned in the path of the goods 14 so that they drop on to the pallet. The number and positions of the contacts 8 may be varied.
