IPC: H01L29/00
Filed: 1965-08-27
Abstract: 1,115,933. Selenium rectifiers. NORANDA MINES Ltd. 20 July, 1966 [27 Aug., 1965], No. 36996/65. Heading H1K. A rectifier comprises a monocrystal of selenium. A typical device is made by cleaving a monocrystal of tellurium along a 10T0 plane, grinding the cleaved surface with emery, polishing with a suspension of tin oxide in water and then annealing at 185 C. in vacuum. Selenium is then vapour deposited epitaxially on the prepared surface to a depth of 1 Á, and a counter electrode applied to the selenium through a mask. Suitable counter electrode materials are cadmium and mono- or polycrystalline cadmium selenide. A copper wire electrode is soldered to the tellurium with antimony-bismuth-tin alloy and a graphite electrode resiliently pressed against the counter electrode. The device is finally electroformed with rectified A.C. applied in the reverse direction, the applied voltage being increased until a stable I-V characteristic is obtained. Addition of chlorine or thallium to the selenium or counter electrode material increases the forward conductivity but reduces the beakdown voltage.

Title: Data storage circuit
IPC: H03K3/356
Filed: 1965-09-01
Abstract: 1,122,411. Transistor storage circuits. INTERNATIONAL BUSINESS MACHINES CORP. 1 Sept., 1965 [13 Oct., 1964], No. 37317/65. Heading H3T. [Also in Division G4] In a data storage circuit having an input circuit comprising two field effect transistors T 2 , T 3 , input pulses are supplied to these two transistors so as to cause data to be stored and removed from the gate-source capacitance Cgs of a storage field effect transistor T 4 . In the shift register shown, three series connected field effect transistors T 1 -T 3 , T 4 -T 6  are interconnected to form a bit storage stage. A reset clock pulse at S 1  causes T 3  to conduct and apply - 10V to the gate of T 4 . This potential is stored by T 4  and DATA at D 1  may be fed in at the same time as a clock pulse is applied to X 1 . Transistors T 1  and T 2  form an AND gate such that if their respective inputs cause them to conduct the potential at the gate of T 4  becomes " 0 " and transistor T 4  stores zero charge or if both or one of T 1  and T 2  remain blocked then T 4  continues to store a voltage of - 10V across its gate-source electrodes. The state of T 4  may be determined by applying a reset clock pulse at S 2  which sets the state of storage transistor T 7 . Then a clock pulse is applied at X 2  to cause T 5  to conduct and sample the condition of T 4 . If T 4  is storing a "0" potential it will remain blocked and T; will remain unchanged or if T 4  is storing - 10V across its gate-source electrodes it will conduct to change the state of charge on the gate of T 7 . With clock pulses applied to all stages in the sequence described above the circuit forms a shift register, DATA at D 1  being inverted at D 2  and restored to its original input condition at D 3 . Alternatively, where it may be required to store the information indefinitely a D.C. holding circuit (Fig. 4, not shown), such as a bi-stable or multivibrator circuit may replace the second series connected transistors T 4 -T 6 , T 10 -T 12 , of each stage. The state of the storage transistor T 4  may be determined by switching a potential to its drain electrode (Fig. 1, not shown). The field effect transistors may be of the insulated gate type and arrangements of " N " and/or " P " types are possible. The transistors T 1 , T 2 , T 4 , T 5  forming the AND gates of each stage may use a split gate structure (Fig. 1A, not shown) and the complete circuit can be formed as a single semi-conductor element.

Filed: 1960-11-10
Abstract: <PICT:0948788/C3/1> In a halide distillation process for the recovery of aluminium the impure sub-halide vapours are passed up a rectifying column down which flows a stream of liquid aluminium. Purified sub-halide vapour is withdrawn from the top of the column and decomposed, while impure aluminium collects at the foot of the column.  A supplemental feed of sub-halide vapour is obtained by treating this impure aluminium with aluminium tri-halide, the necessary heat being supplied either by conventional means or preferably by the exothermic reaction of chlorine with the aluminium. In the form of apparatus illustrated, impure aluminium is treated with aluminium tri-chloride in converter 10 and the vapours passed through conduit 22 into column 12 which is filled with suitable refractory packing material 28.  Rectified subhalide vapour passes via conduit 42 to condenser 14, from which liquid aluminium is withdrawn through pipe 55, aluminium tri-chloride vapour leaving by pipe 48 and returning to converter 10.  Part of the aluminium is returned to column 28 via pipe 57 where it takes up impurities and collects in boiler 16 from which it is withdrawn through conduit 34. The supplementary feed of halide is produced in boiler 16 by blowing in through perforated pipe 36 the appropriate mixture of chlorine and aluminium tri-chloride to maintain the desired temperature.

Title: A process for the production of a clarified malt extract
IPC: C12C1/18
Filed: 1961-10-31
Abstract: A clarified malt extrat is produced by germinating barley for up to approximately four days, thereby increasing its enzyme content, disintegrating the germinated barley with water to make a slurry, separating the starch from the slurry to yield an effluent rich in barley enzymes and proteins, heating the starch-free effluent to a range of temperatures which progressively increase from 122 DEG F. to 144 DEG F. over a period of up to one hour, so as to activate the enzymes, clarifying the effluent, remixing the clarified effluent with the separated starch, and subjecting the mixture of starch and clarified effluent to heating at a range of temperatures which progressively increase from 144 DEG F. up to 170 DEG F. over a period of substantially 60 minutes, thereby converting the starch to soluble sugars, so as to produce a clarified malt extract.  The separated starch may be dried and reconstituted with water to a fluid suspension, before the dried starch and water are mixed with the clarified effluent.  Similarly, the clarified effluent may be either concentrated to a gravity of 1,300 or dried to a powder for reconstitution by the addition of water, prior to the mixing with the separated starch.  When a stronger malty flavour is desired, the starch may be heat treated before the remixing.  Conventional brewers adjuncts may be added to the germinated slurry just after disintegration, and starch from extraneous sources and a liquor extract from boiled husks may be utilised.  The clarified malt extract may be used directly for the manufacture of beer or may be concentrated to a gravity of 1,300 for packaging.  Specifications 872,391, 872,392, 872,393, 872,394, 872,395, 872,396, 872,397, 872,398, 872,399, 872,400 and 970,940 are referred to.
