Title: Improved machine for moulding dough blanks for cookies
IPC: A21C11/08
Filed: 1934-06-18
Abstract: 429,318. Moulding dough by rolling- machines. WERNER, F. C., 640, Front Avenue, Grand Rapids, Michigan, U.S.A. June 18, 1934, No. 18012. [Class 87 (ii)] In machines for moulding dough blanks for cookies wherein dough is pressed into recesses 13 in a rotating drum 12 from which the dough blanks are removed by a moving transfer belt 21, the belt is guided around the drum from a point adjacent the lowermost part of the drum to a point approximately 90 degrees therefrom such that the blanks are removed in an approximately vertical plane. The belt 21 may be of canvas and passes over rolls 22, 26 and a stationary shoe 25. The roll 26 may be provided with a rubber or other resilient cover 27 and is adjustably supported so as to compress the dough blanks. The dough is fed from a hopper 10 by a pressure roll 16 and cut off by a knife 19. The roll 22 is adjustably mounted near the drum 12 so that the belt moves in a straight line from the drum to the roll 22. The belt 21 may be driven by frictional contact with the blanks in the drum which is positively driven. The dough blanks may be received on moving pans 31.

Title: Improvements relating to the production of transistors
Inventor: THOMAS ARTHUR DERRICK
IPC: H01L29/06
Filed: 1958-06-05
Abstract: 872,531. Transistors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 15, 1959 [June 5, 1958; March 24, 1959], Nos. 18012/58 and 10212/59. Class 37. A drift transistor is produced by diffusing an impurity characteristic of one conductivity type into the surface of a semi-conductor body to form a graded resistivity surface layer, alloying a pellet of opposite type impurity into the layer to form a PN junction, forming a depression on the other side of the body and effecting a connection to the inner body region within the depression. In one example antimony is vapour diffused into a wafer of P-type germanium, the heat treatment being such as to provide an N-type graded layer B (Fig. 2), and a pellet E of aluminium, indium, indium gallium or indium aluminium is then alloyed with the layer to form a PN junction J1. For this purpose, the wafer may be gold-antimony soldered to a molybdenum plate 5, the pellet E being fused within hole 4 in the plate. A depression D is then formed in the opposite side by, for example, electrolytic etching in a bath of potassium hydroxide with pellet E as the anode, and a cathode P shaped to localize the etching action. Masking is provided by means of stopping compound R. Etching may be enhanced by a light beam. Alternatively the depression could be formed by ultrasonic drilling or etching with a jet of chlorine. A pellet C (Fig. 4) containing indium or other acceptor is then lightly alloyed to provide an ohmic contact to the inner P-type region. This provides a PNP drift transistor, the surface N-layer constituting the graded base zone. A PNIP transistor may be produced by using an intrinsic (or slightly N-type) wafer whereby the pellet C then forms a PI junction with the intrinsic inner region. Silicon, a silicon-germanium alloy, an AIIIBy, AIIBIV or AIVBIV compound may be used in place of germanium.

Abstract: 393,761. Fluid - pressure actuated valves. VICKERS, H. F., 7752, Dubois Street, Detroit, Michigan, U.S.A. June 28, 1932, No. 18206. Convention date, July 23, 1931. [Class 135.] Safety valve.-A relief valve 8 for oilpressure systems is gradually inwardly converging and concave from the point of contact with the valve seat 16 to the discharge end 21 of the valve. The oil flowing from the conduit 6 into the exhaust passageway 19 produces a partial vacuum in the axial passage 22 of the valve. The valve is actuated by a piston 13, oil pressure being admitted to the rear of the piston through a restricted conduit 11. The valve 8 is held on its seat by a weak spring 9. When the pressure of the oil exceeds a predetermined amount, the auxiliary valve 17 opens and the pressure in the space 12 behind the piston 13 falls, thus allowing the pressure in the conduit 6 to raise the piston and open the valve 8. The pressure at which the valve opens may be adjusted by the screw 18 for adjusting the control spring of the auxiliary valve 17.

Title: Hydrolysis of aliphatic dinitriles
IPC: C07C231/06
Filed: 1956-06-19
Abstract: Aliphatic cyanoamides and cyanocarboxylic acids are produced by effecting hydrolysis of one of the two nitrile groups of aliphatic dinitriles in which the nitrile groups are separated by more than three methylene groups using aqueous ammonia or aluminium hydroxide at a temperature of 100-250 DEG  C.  Advantageously, the dinitrile is treated in the form of an aqueous emulsion for 1-10 hours with approximately 10 times the amount of a solution of the base. Preferably the temperature is from 180-200 DEG  and the reaction time 3 hours.  An alcoholic aqueous solution can be used but results in less conversion.  When ammonia is used, a concentration of 1-5 N is suitable.  The product is worked up by filtering, washing with alcohol, evaporating, dissolving in ethyl acetate, filtering and evaporating the solution and finally distilling in vacuum.  In examples: (1) adiponitrile is hydrolysed with 2N ammonia and yields o -cyanovaleramide and o -cyanovaleric acid with adipamide as a by-product; (2) adiponitrile is hydrolysed with aqueous aluminium hydroxide; (3) pimelic acid dinitrile hydrolysed with ammonia yields o -cyanocapronamide; (5) suberic acid dinitrile similarly treated gives o -cyanooenanthamide.
