Patent GB-601977-A (GB)
Title: Improvements in or relating to method of and apparatus for making nuts or similar articles
IPC: B21K1/64
Filed: 1945-03-19
Abstract: 601,977. Forging nuts; shearing. NATIONAL MACHINERY CO. March 19, 1945, No. 6870. Convention date, Aug. 3, 1944. [Class 83 (iv)] A method of making nuts and the like includes the step of confining the blank in a die and upsetting it into a dished or concavo-convex form so as to force one end of the side wall of the blank laterally against the side walls of the die. Rod stock S is fed through an opening 11 in the bed frame of the machine into a sleeve 14, Fig. 1, to an extent determined by a plunger 16 abutting a stock gauge 18. The sleeve 14 which is integral with an arm 13 is moved to shear off the projecting portion of the stock and to carry the blank to a position in front of a die of circular cross-section, but with chamfered bottom edges. A punch carried by a reciprocating header engages the outer end of the plunger 16, thus forcing the blank into the die to shape it as shown in Fig. 2a. The blank 25 is then ejected, turned over and forced under comparatively light pressure into a hexagonal die so as to form a partially hexagonal blank. After ejection, the blank is again turned over and is forced into another hexagonal die 33, Fig. 4, by a punch 38. The bottom of the die and the nose of the punch have substantially parallel conical faces 34, 40, respectively, by which the blank is given a dished or concavoconvex form. A nose 37 at the end of a knockout pin 36 enters the other end of the blank and spreads the metal radially outwards to fill the corners of the die. On ejection, the blank is again turned over and is forced by a punch 50 into a die 46, Fig. 5, in which the blank is flattened, thus forcing the other end of the blank into close contact with the corners of the die. This die also has a bottom wall 47 shaped to form a washer face on the blank, while the punch has a portion 51 which flattens the inner portion of the outer surface of the blank, but leaving it slightly convex at the outer edge. For the next operation the blank is supported in a die 61, Fig. 6, and pierced by a punch 69 having a working end portion 76 and a smaller relieved portion 77. On the retraction of the punch the end portion 76 ejects the blank from the die and then withdraws into a sleeve 72 which strips the blank from the punch. Specification 426,845 is referred to.

Abstract: 382,851. Railway rails. MICHELIN ET CIE, Clermont-Ferrand, Puy-de-Dome, France. March 8, 1932, No. 6973. Convention date, April 21, 1931. [Class 104 (ii).] The running- surface of a railway track is widened by attaching to each rail, or building up alongside it, an extension in order that railway vehicles having wheels with pneumatic tyres may be provided with tyres of larger size. In the construction shown in Fig. 1, a girder 1 of channel section is secured alongside the track rail A. The side 2 of the girder forms the extension of the running-surface while the other side, 3, rests on the sleepers or in contact with the ground. The side 3 is preferably cut away to form a recess 4 to accommodate the foot D of the rail. In the construction shown in Fig. 3, an L-section girder 5 is mounted beside the rail and the space between them is filled with cement, asphalt, or other material which sets solid when cold. A plate 8 of metal or other hard material covers the filling 7. In other constructions, the extension piece is secured directly to the rail by means of bolts passing through the web of the rail. In another construction, shown in Fig. 6, the extension consists of a box-like construction comprising side walls 19 connected by an horizontal wall 20 which constitutes the running-surface, supporting ribs 21 being provided if desired. Alternatively, the extension may be reinforced by cross pieces or by filling it with concrete or other suitable material.

Title: Process for treating fermented beverages to remove proteins promoting colloidal turbidity
IPC: C12H1/044

The calcium polysilicate preferably consists of agglomerates of primary particles sized less than 0.1m , preferably less than 0.05m , and of density between 80 and 150 g/l.  The calcium polysilicate is prepared by reacting naturally occurring substances which consist of, or contain large amounts of, silicon dioxide e.g. quartz sand, with calcium hydroxide in aqueous suspension at a temperature of from 150 DEG  to 250 DEG C. and under pressure, and then treating the suspension with a dilute acid such as acetic acid or hydrochloric acid, until the CaO content is between 0.1 and 5% by weight; the treatment with acid is preferably carried out at a temperature of between 60 DEG  and 80 DEG C.  The molar ratio of SiO2 to CaO before the reaction should be between 1:0.5 and 1:1.5 and the particle size of the starting material is preferably between 1m  and 20m .ALSO:A calcium polysilicate useful for the removal by adsorption thereon of proteins promoting colloidal turbidity in fermented beverages contains 0.1-5.0% by weight of calcium, expressed as CaO, and is in the form of 1-15 m  agglomerates of primary particles sized less than 0.1 m , preferably less than 0.05 m , and of density between 80 and 150 g./l.
