Title: An improved process for producing soluble cocoa powders
IPC: A23G1/56
Filed: 1925-11-09
Abstract: 262,239. Bollmann, H. Nov. 9, 1925. Cocoa preparations. - The solubility of cocoa powder is increased by the addition of a small . quantity, e.g. two per cent, of phosphatides derived from vegetable materials, especially soya beans. The phosphatides, e.g. lecithin, may first be mixed in a mill with a small quantity of cocoa powder which is then distributed through the main mass. The nourishing value of the treated cocoa is increased and the fat particles separate less readily from the liquid. The phosphatides used may be so purified that their phytosterol content is retained, e.g. by first adding water, if necessary, and then distilling under reduced pressure, after removing by centrifugal means the main quantity of the oil derived in their recovery from oil seeds.

Title: Improvements in or relating to the manufacture of knife blades
Inventor: CHAMOUARD ANDRE
IPC: A01D34/14
Filed: 1958-09-05
Abstract: 925,970. Making knife blades; bending; forging. MASSEY-FERGUSON S.A. Sept. 7 1959 [Sept. 5, 1958 ; July 11, 1959], Nos. 28554/58 and 23890/59. Classes 83 (2) and 83 (4). A method of making knife blades for agricultural machines comprises perforating a strip along lines defining the ultimate cutting edges of the blades, performing a blade processing operation on the edges and then making other perforations to merge with the first and so part the blades from the strip. A strip 11, Fig. 3, is advanced step-by-step while successive punching operations are performed. The first trims the edges of a portion and forms the oblique slot 16 shown in full lines and forms positioning holes 13, 15. The second trims a further portion and removes the parts shown in dotted lines while the third removes the parts shown in dot-dash lines. The areas shown by cross-hatching are those removed later to part the blades S from the strip. Before separating the blades, the strip is pressed between a die 21, Fig. 5 and a matrix 30, Fig. 9, which bend downwardly and form teeth in the edges of the slots 16. The strip is then ground along the plane X-X, Fig. 8, to produce a bevelled serrated cutting edge E. The die 21 comprises two ridges 22 arranged in V-formation and each having inclined grooved faces 23 with triangular facets 25, 26 at each end. The matrix 30 has channels 31, 32 conforming to the slots 16 in the strip and flanked by downwardly-inclined grooved faces 33. Three pins 36 co-operate with locating holes 15 in the strip. In order to minimize lateral flow of metal the grooves 24 of the die alternate with those 34 of the matrix, Fig. 11A, and all the grooves are wider and deeper adjacent the cutting edges of the blades and merge to form points along the outer sides of the inclined faces. Also, the die teeth are asymmetrical and the matrix and die are slightly offset so as to increase the difference between the distances T and t until the resultant reactions R1, R2 of the metal on the dies bisects the apex angles of the grooves. In one modification, the blades are formed without teeth and in another, teeth are formed on one side only and the edges are not bent, the cutting edge being formed by grinding along the line A-A, Fig. 23, after separating the blades from the strip.

Title: Improvements in or relating to automatic telephone exchanges
IPC: H04Q11/04
Filed: 1965-07-06
Abstract: 1,102,498. Automatic exchange systems. GENERAL ELECTRIC CO. Ltd., and B. S. BARNABY. 6 July, 1966 [6 July, 1965], No. 28581/65. Heading H4K. A conference facility is provided in a time division multiplex exchange in which a tune slot seized for a calling subscriber is used to connect a register common to the exchange, the register governing connection to the wanted subscriber and normally being released as soon as a path between the subscribers is established with the use of the seized time slot, such release being inhibited in the event of a calling subscriber signalling the register that a conference call is required, the register staying in service in the same time slot which is consequently employed in connecting further subscribers. The exchange is as described in Specification 1,102,500. A special conference key at a substation causes the register to operate a conference circuit 62 which need be no more than a bi-stable circuit. With 62 operated, release of the register 9, which normally occurs when time slot pulses on lead 33 gate ringing tone generator 35 to highway 1, is prevented by inhibition of gate 63. Since release on ringing is denied a timing circuit 64 eventually releases the register.
