Title: Making shaped articles from particulate material and an anaerobic  adhesive
IPC: B22C9/12
Filed: 1973-04-14
Abstract: 1419800 Foundry moulds; anaerobically curing compositions CIBA-GEIGY AG 13 March 1974 [14 April 1973 (2)] 18109/73 and 18110/73 Heading B5A Shaped articles, e.g. foundry cores and moulds are moulded from a mixture of particulate solid material and an anaerobically curing adhesive, and curing the adhesive to bond the particles together in an oxygen-free environment. The oxygen-free environment may be attained by evacuating or displacing the air or other oxygencontaining gas by a gas or vapour which does not inhibit the curing, e.g. nitrogen. The shaped article may be wrapped in an airimpermeable film or coated with an air-impermeable sealing composition formed in situ. Curing may be accelerated by heating by direct heat, by using a hot inert gas to displace the oxygen-containing gas or by dielectric heating, e.g. radio-frequency heating. The adhesive preferably comprises an acrylic acid ester, a hydroperoxide or peroxide catalyst and an accelerator therefor. The particles, e.g. sand may be coated in separate portions with interacting components of the adhesive composition, e.g. by a laboratory mixer, tumbling in a rotating drum, spraying on dipping.

Title: Process for the production of cyanogen chloride or cyanogen bromide
IPC: C01C3/00
Filed: 1976-05-04
Abstract: 1525343 Cyanogen chloride or bromide DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT 4 May 1976 [12 May 1975 (2) 15 May 1975 (2)] 18135/76 Heading C1A Cyanogen chloride (or cyanogen bromide) is made by reacting HCN and HC1 (or HBr) with H 2 O 2  in aqueous medium in the presence of Cu<SP>2+</SP> and Fe<SP>3</SP>+ ions at above atmospheric pressure, typically 1À5-16 bars whereby CNCl (or CNBr) formed is dissolved in the aqueous medium and thereby separated from 0 2  and N 2  gases. The reaction is typically carried at pH of 0À1-0À5 and 40-60 C. The reaction solution which is continuously recirculated typically contains 0À5-0À005 mol/1 of both Cu<SP>2+</SP> and Fe<SP>3</SP> + ions. CNCI (or CNBr) dissolved in the reaction solution may be recovered by releasing the pressure on the solution whereby the CNCl content is reduced followed by stripping the solution e.g. at 100 C to remove CNCl, HCN and C0 2 . This gas mixture is suitably washed with the pressure released solution from the earlier stage to dissolve HCN and C0 2 . The recirculated solution may be passed through a cation exchanger to recover cupric and ferric ions and allow the water introduced with the reactants and that formed during reaction to be passed to waste, the recycling solution being regenerated by passing HCl through the bed on which the ions have been fixed. In an embodiment all or part of the HCl is formed in situ in the recirculating solution by reaction of Cl 2  and HCN, either under elevated or normal pressure.

Title: Improvements in or relating to safety devices for razor blades and to safety razors
IPC: B26B21/50
Filed: 1923-07-13
Abstract: 224,578. Salerni, P. M. July 13, 1923. Razors, safety. A safety-razor blade of the type which is comparatively rigid and approximately wedge-shaped in cross-section is provided with a guard member which is carried by the blade itself and extends along the edge thereof at a little distance therefrom so as to be free to turn or to be turned to a limited extent to each side of the blade and thus avoid injury to the fingers in whetting it by devices of the type in which the blade is rocked at the end of each reciprocation over the whetting surface or in manipulating it. As shown the guard member b, Figs. 1, 3 and 4 has resilient side arms b<1>, b<2> pivoted to the blade a by projections engaging recesses d in the ends thereon; at the opposite side of the pivot to the blade edge the arm b<1> carries a conical or tapered pin e disposed in a recess e<1> in one end of the blade so that the movement of the guard is limited and the centre of the recess is out of line with the centre of the recess d and the edge of the blade so that the movement of the guard member is greater on one side of the blade than on the other. The movement of the guard is adjusted by a milled collar e<2> rotatably mounted on the pin e and having a rounded teat e<3> which has frictional engagement. with one or other of a series of recesses in the inclined or helical inner face of the arm b<1>. The arm b<2> similarly carries a, projection f<1> formed by a steel sphere embedded therein and engaging with one or other of a pair of shallow conical and closely adjacent recesses f in the end of the blade and arranged symmetrically with respect to the recess e<1>; as the guard is turned from one side of the blade to the other the projection f<1> is caused to mount up the side of the recess in which it is. located against the resilience of the arm b<2> and eventually to pass over the junction between the two recesses when the resilience of the guard member causes the latter part of its movement down towards the centre of the other recess to take place automatically. The blade and guard member may be used in known types of holders e.g. the holder described in Specification 184,514 or the guard member b may form the sole guard in shaving when the blade holder may consist merely of a handle l, Fig. 9, and a bracket or clip device g into which the blade and guard member are slid endwise; a spring-pressed sphere h disposed in the handle engages one or other of recesses i arranged one on each side of the blade and midway between its ends. The recesses e<1> f may be in the middle of the ends of the blade and the pivots d out of line with them and the edge of the blade or the parts e, f may be out of line with the pivots d, recesses e<1>, f and the edge of the blade. Specifications 7066/09 and 5355/11 also are referred to.
