Title: Punch and stripper assemblies
IPC: B26F1/02
Filed: 1977-02-23
Abstract: 1536992 Punches and strippers HOUDAILLE INDUSTRIES Inc 23 Feb 1977 [28 July 1976] 07619/77 Headings B3W and B3Q  A punch and stripper assembly has a stripper spring 23 preloaded by engagement with a head 19 screwed to one end of the punch 12 and a washer 24 held in place by a retainer 27 bearing on a shoulder 15 on a punch. A stripper sleeve 31 held on the punch by engagement of a retainer 34 with a shoulder 18 on the punch, transfers a reactive force from the workpiece to the retainer during punching to stress the spring. The retainer 27 is a split ring with a flange 30 located in a bore 25 of the washer. After grinding of the punch, the head is backed off by the amount removed from the punch. When maximum grinding has been carried out the retainer is inverted, the sleeve still abutting the main part of the washer but the shoulder 15 engaging the flange 30 to maintain the punch tip in its initial relation to the sleeve end. Alternative forms of retainer which do not allow a second grinding are a gapped ring and an oversize ring which are permanently deformed to make a sliding fit on the reduced diameter portion 16 of the punch shank. The punch may be for cutting or forming.

Title: Improvements in and relating to the production of hydrogen and sulphur from hydrogensulphide
Inventor: WEINER JOSEPH GEORGE
IPC: C01B3/00
Filed: 1961-03-03
Abstract: Hydrogen and sulphur are obtained from hydrogen sulphide by passing it into contact with a lower sulphide of iron, cobalt, or nickel to form hydrogen and a higher sulphide of the metal, which, after removal of the hydrogen, is heated to liberate sulphur and regenerate the lower sulphide.  The contacting of hydrogen sulphide with the lower sulphide may be at elevated temperature, e.g. 500 DEG  F. to 1,000 DEG  F.  The higher sulphide may be heated at a temperature above 1,300 DEG  F. and the sulphur removed by a stream of inert gas, e.g. carbon dioxide, and/or nitrogen, or it may be heated in vacuo. The lower sulphide may be a monosulphide and the higher a bisulphide. The lower sulphide may be alone or supported on a carrier, e.g. bauxite, alumina, or silica gel.  The hydrogen sulphide may be an impurity in a gas, e.g. natural hydrocarbon gas.

Title: Improvements in or relating to leak valves
Inventor: HARRISON EDWARD ROBERT
IPC: F16K1/38
Filed: 1952-03-27
Abstract: 727,585. Temperature-responsive actuating elements. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 7, 1953 [March 27, 1952], No. 7823/52. Class 64 (2). [Also in Group XXIX] A thermally-responsive actuating-element which permits only small flows of a gas comprises a casing with, at one end, a member having a central port therein and, at the other end, an axial obturating device co-operating with the port, the obturating device being integral with and constructed of the same material as the casing ; and means is provided to maintain a temperature difference between the casing and the obturating device. In an embodiment, an outlet tube 3 sealed into one end of the casing carries a part-spherically shaped valve seat 1, and the obturating or closure member 5 is formed to a similar shape on the end of a tube 6 projecting through, and sealed into, the other end of the casing. Gas flows into the casing through a pipe 8. An openended tube 9 mounted in, and a further tube 11 jointed into, the tube 6 allows of a fluid at a constant temperature being circulated through the tube 6 and valve head 5. The casing is lagged at 13 and an electrical heating coil 12 and a tube containing a thermocouple 15 are embedded in the lagging. As the casing, the valve seat, and the closure member are all of the same material, i.e. boro-silicate glass, a variation in the temperature difference between the casing and the tube 6 will cause an alteration in the cross-section of the flow passage between. the valve head and its seat. According to the Provisional Specification, the valve head and the seat may be conically shaped, the fluid being controlled may flow through the tube 6, and the tube 6 and the casing may have different coefficients of thermal expansion, i.e. silica and boro-silicate glass.

Title: Laminated glass
IPC: C09J161/22
Filed: 1929-03-11
Abstract: 332,234. Gardner, H. A. March 11, 1929. Compound transparent sheets.-A laminated glass consists of a number of glass sheets united together by a non-brittle binder consisting essentially of a synthetic resins of the toluolsulphonamide-aldehyde type. The resin may be incorporated with cellulose compounds such as viscose, celluloid, &c. In one example 50 gms. of para toluol sulphonamide formaldehyde resin are dissolved in 50 gms. of volatile solvent such as acetone. The cleaned glass sheets are coated on one side with this solution, partially dried, and pressed together, preferably with the application of heat. In a second example, the glass sheets are coated with a cement consisting of 25 gms. of low viscosity nitrocellulose, 125 gms. of acetone and 50 gms. of paratoluol sulphonamideformaldehyde resin, and are then partially dried and pressed. The nitrocellulose in this mixture may be replaced by other cellulose esters or ethers such as cellulose acetate. In a third example, a cellulosic ingredient may be added to the binder given in the first example and a similar ingredient, such as viscose, celluloid, &c., may be used in thin sheet form between the coated glass sheets. The thin sheets may themselves be coated with the cements given in the above examples prior to lamination. In a fourth example, the toluol sulphonamide-aldehyde resin may be applied directly to the glass sheets in a semi-fluid condition or a mixture of said resin with a cellulose ester or ether may be similarly applied. Alternatively, a thin sheet of the resin, or of a mixture of the resin and a cellulose ester such as nitrocellulose may be interposed between glass sheets which may or may not be coated with the above mentioned cements. In another method, thin sheets of celluloid, viscose or the like may be combined with the resin-containing sheets to form the non-brittle binding laminae. Specification 317,456 is referred to.
