Patent GB-989102-A (GB)
Title: Method of treating bottle corks
Inventor: GULTIG HEINRICH
IPC: A61L2/18
Filed: 1961-07-14
Abstract: Bottle corks are sterilized by impregnating them with an aqueous liquid and simultaneously and/or subsequently exposing them to the action of a sterilizing agent, e.g. sulphurous acid or formaldehyde, and are then maintained in a moist condition in an impermeable container, e.g. a polythene bag, so as to be sufficiently moist to be ready for immediate use for corking bottles.  The aqueous liquid may be an aqueous emulsion containing a high melting paraffin hydrocarbon wax and the sterilizing agent. The sterilizing agent may be supplied to the corks inside the bag in the form of a gas after they have been previously soaked and partly dried.  This may be effected by introducing the sterilizing agent to the bag as a pressurized liquid which evaporates immediately the liquid is decompressed.

Abstract: 930,154. Cutting confectionery. BAKER PERKINS HOLDINGS Ltd. July 19, 1961 [July 26, 1960], No. 25965/60. Class 87(2). Butterscotch is fed from a shoot 12 on to a cooling band 13, having rubber strips 14 to form a trough, beneath adjustable scraper blades 19, and is then cut, leaving a thin web, by blades 42 carried by chains 20. The blades are depressed just before the butterscotch enters the pass and are raised clear before the end of the pass by a pair of cams 41. The butterscotch is discharged on to a shoot 23 to a chocolate enrober or to a vibrator which breaks the sheets into individual blocks. A guide cam 73, Fig. 6, which co-operates with rollers 32 tilts the cutter so that the leading edge of the cutter frame 22 does not dig into the butterscotch. A similar cam prevents the trailing edge from fouling the butterscotch at the delivery end. The blades 42 are withdrawn from the butterscotch by a spring 36. To facilitate withdrawal, the blades may be given a jigging motion by forming indentations in the portions 41A of the cam rails. The cutters and band are moved at the same speed by interengaging belts 45 on the band and grippers 46 on the cutter frames. In a modification, Figs. 7 to 9 (not shown), a hopper with adjustable end walls is provided for feeding the butterscotch. Specification 405,276 is referred to.

Title: Associative stores
Inventor: LOHREY FRED HELMUT

Filed: 1971-04-19
Abstract: 1281808 Transistor bi-stable circuits INTERNATIONAL BUSINESS MACHINES CORP 19 April 1971 [20 April 1970] 26433/71 Heading H3T [Also in Division G4] Each cell of an associative storage array comprises a pair of cross-coupled transistors T1, T2 and a pair of input/output transistors T3, T4 connected as shown. A further pair of load transistors T5, T6 of conductivity opposite type to transistors T1, T2 may be provided between points A, B and a control voltage source V 1 . In a normal read operation, the potential of word line W/L is raised so that the transistor T3 or T4 with its base connected to that of the conducting transistor T2 or T1 conducts to provide an output on the B 1 or B0 bit line, the transistors T3, T4 being held non-conductive while the cell is not being accessed. In a write operation, the potential of the B0 or B1 bit line is decreased while that of the word line is raised to cause T3 or T4 to conduct and reduce the potential at point A or B until the transistor T1 or T2 with its base connected to that point is biased off and the other transistor T2 or T1 on. To perform associative read-out, the potential of bit line B0 or B1 is lowered to approximately that of the word line. If the cell is in the "1" state with T2 on, and a search for a "0" bit is made by lowering the potential of bit line B1, T3 conducts to cause current flow in the associative sense line A/S which is detected as a mismatch by amplifier 28. If the cell is in the "O" state with T1 on, T3 does not conduct, and if all cells connected to common line A/S similarly indicate matching conditions, a match output is obtained from amplifier 28. Voltage V1 may be varied to make the resistance of the cell very low so that read and write operations can be made rapidly with low power dissipation.

Abstract: 769,507. Converting. BRITISH THOMSONHOUSTON CO., Ltd. Aug. 26, 1955 [Sept. 13, 1954], No. 26453/54. Class 38 (2). In a circuit comprising semi-conductor devices such as germanium rectifiers for converting power between A.C. and D.C. circuits or between A.C. circuits of different frequencies, the delay in the carrying of current by each rectifier at the beginning of each conducting half-cycle caused by a saturable reactor, as described in Specification 767,102, is made adjustable by premagnetizing the reactor to an adjustable point on the unsaturated part of its magnetization characteristic, which has a pronounced knee. The delay corresponds to the volt seconds consumed in completing the saturation of the reactor by a negligibly small load current. If the unsaturated part of the characteristic has a definite slope, each reactor may be premagnetized by a small adjustable D.C., Fig. 1 (not shown). If the unsaturated portion of the curve is substantially vertical, the premagnetization may be by an impulse of adjustable volt seconds. Fig. 5 shows two rectifiers 5, 8 of a three-phase bridge connected rectifier sup. plied from a transformer 3, having in series saturable reactors 11, 14 with constant D.C. premagnetization windings 25, 26, and impulse windings 27, 28. The impulses are derived from circuits fed from an A.C. source and including rectifiers 33, 34, saturable reactors 35, 36 and reactors 31, 32 saturable to an amount which determines the impulse value by D.C. from supply 37 through smoothing inductor 38 and variable resistor 39. Surge diverting means 40, 41 each comprising a resistor and capacitor may be connected across each rectifier. Alternatively each reactor may control the current through a pair of rectifiers, impulses of alternate polarity being supplied to the premagnetizing winding. In a six-phase connection each reactor may carry two main windings connected to phases 180 degrees apart, Fig. 7 (not shown). The control may be associated with tap changing gear on the transformer.
