Title: Process for the Sweetening of Beers
Inventor: GREEN JAMES WILLIAM
IPC: C12C11/00
Filed: 1967-12-13
Abstract: 1,174,619. Sweetening beer. A.B.M. INDUSTRIAL PRODUCTS Ltd. Nov.26, 1968 [Dec.13, 1967], No.56585/67. Heading C6E. Beer of predetermined residual glucose concentration is produced by yeast-fermenting a beer wort to provide a beer, removing substantially all the yeast from the beer, adding a quantity of the enzyme amyloglucosidase to the beer, storing the beer until the enzyme has broken down sufficient of the residual yeast-unfermentable carbohydrate present to produce the predetermined concentration of glucose, and then inactivating the enzyme by heat-treatment of the beer. Preferred features of the process are as follows: (1) the predetermined residual glucose concentration is to be not less than 0À1% and not more than 3À5% dextrose equivalent by weight; (2) the enzyme is an amyloglucosidase produced by a species of the mould Aspergillus; and (3) the enzyme is allowed to act during three days storage at 60-65‹ F. and thereafter the enzyme is inactivated by heating the beer to 180‹ F. and maintaining it at this temperature for 15 seconds. The glucose produced may be used as a partial replacement for priming sugar normally added just before bottling.

Filed: 1966-12-19
Abstract: 1,142,950. Pipe joints; pipes. HEPWORTH IRON CO. Ltd. 18 Dec., 1967 [19 Dec., 1966], No. 56614/66. Headings F2G and F2P. A coupling socket for a spigot-and-socket pipe coupling comprises a slightly resilient synthetic plastic socket, a sealing ring 4 of natural or synthetic rubber, having an outwardly projecting annular flange 5 abutting the rim of the socket and an annular sealing head 13 projecting inwardly and joined to the flange 5 by an intermediate ring portion 8 lying against the inside of the socket, and a channel-section locking ring having axially extending arms 10 and 11 overlying the outside of the socket and the intermediate sealing ring portion respectively and a base portion 12 abutting the flange of the sealing ring. The socket and locking ring may be of the same material, such as rigid polyvinyl chloride, polycarbonate, polyacetal, acrylonitrile butadiene styrene, and polypropylene, so that they may be secured together by solvent welding. The socket may be at the end of synthetic plastic pipe length, being of enlarged diameter so that the socket/pipe junction defines a shoulder adapted to act as an abutment for the inserted spigoted end of similar synthetic plastic pipe length. Alternatively, the socket may be at the end of a synthetic plastics sleeve, the other end of which is a force fit or adhesivelysecured on one end of a clayware or synthetic plastics pipe. Again, as shown, the socket is formed at one end of plastics sleeve which has a similar socket at the other end, the sockets receiving plain-ended plastics or clayware pipes. The sleeve is provided with one or more integral small projections or with a flange 2, which is or are intended to act as abutments for plain-ended spigoted pipe lengths when inserted into the sleeve. The axial length of the sealing ring flange is greater than the radial thickness of the sealing ring intermediate portion 8 to reduce the possibility of the sealing ring being pulled out. As shown on the right-hand side of the Figure, the sealing ring head portion is provided with an annular cavity 14 to accommodate sealing ring material which is displaced when a spigoted pipe end is inserted into the socket.

Title: Semiconductor oscillators
IPC: H01L47/02
Filed: 1968-11-29
Abstract: 1,211,288. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 29 Nov., 1968 [4 Jan., 1968], No. 56679/68. Heading H1K. [Also in Division H3] The energy-spaced, differential mobility, two-valley conduction band condition necessary for the occurence of the Gurr effect is induced in crystals of materials such as Ge, Si and PbTe, which have at least three conduction band minima normally superimposed, by the application of uniaxial stress along a particular crystal axis, oscillations being produced by the application of an above-threshold potential gradient along a second axis. The axis along which stress is applied is preferably selected so as to maximize the energy splitting between the valleys, while the direction along which the potential gradient is applied is governed by the need to maximize the ratio of mobilities in the lower and upper valleys while maintaining as high a mobility as possible in the lower valley. In the example shown compressive stress is applied to an N-type Ge crystal 14 along the [111] axis, the field being applied along the [112] axis. These axes may also be interchanged, and in this case two of the four initially equivalent conduction band minima are intermediate the other two as regards both mobility and energy. A less favourable arrangement involves application of force along the [110] axis and field along the [112] axis in Ge. For each configuration there is a preferred range of stress values for which the threshold field required to generate oscillations is a minimum. In Si a suitable arrangement comprises application of stress along the [100] axis and application of field along the [010] axis. Stress may be applied by a lever arrangement, the 'crystal being mounted between two optically polished sapphire blocks. The device may operate in oscillatory, domain quenching or limited space-charge accumulation modes.

Title: Avalanche diodes
IPC: H03B9/12
Filed: 1970-12-04
Abstract: 1319796 Semi-conductor devices WESTERN ELECTRIC CO Inc 4 Dec 1970 [10 Dec 1969] 57663/70 Heading H1K An avalanche diode includes in succession a rectifying junction, a high conductivity avalanche region and a low conductivity transit region, so that at avalanche breakdown a concentration of avalanche region majority carriers travels through the transit region, the material on the other side of the junction being such that no accumulation of avalanche region majority carriers can occur there. The device may comprise a P + contact region 24, a P region 25 adjacent the junction, an N avalanche region 26, an intrinsic transit region 27 and an N+ contact region 28. Because of the low conductivity of region 25 an electric field exists therethrough, and prevents the accumulation of avalanche region majority carriers therein. Region 25 is preferably thicker than the diffu-  sion lengths of said majority carriers. The carriers diffuse across the junction and in the prior art returned following avalanching, reducing build up time of the succeeding pulse and interfering with synchronism of the microwave arrangement of which the diode forms a part. In the present invention the carriers are returned by the field in region 25 to region 26. In an alternative embodiment the P + and P regions 24, 25 may be replaced by a metal Schottky barrier contact, which also prevents accumulation of the carriers.

A diaphragm 4 having a thickness gradually increasing from its periphery to its center portion 12 is reciprocated by liquid in a chamber 35 to pump gas in a working chamber defined by the other side of the diaphragm and the opposed surface of a valve head 3, and the centre portion 12 is drawn by a spring 18 away from the working chamber whereby during a working stroke the diaphragm is forced by the liquid into contact with the head 3 progressively from its periphery to its centre portion. The progressive contact prevents gas pockets from being formed between the diaphragm and the head 3. The liquid in the chamber 35 is supplied through a connection 5 and is forced against the diaphragm by a piston 6 reciprocated by a cam 43 against a return spring 7. A poppet valve 37, 41 is normally urged by a spring 38 to close a sealing in a bush 36 disposed in the piston 6, but if the pressure in chamber 35 becomes excessive, the valve opens to relieve liquid to the connection 5.

Abstract: 1368965 Selective signalling MECHANICAL ENG COMPUTER AIDED DESIGN CO Ltd 20 Dec 1971 [22 Dec 1970] 60860/70 Heading G4H In a digitizing table unit, a freely movable index may be placed at any position on a first table surface, a bug below the surface being movable by means of servomotors to a corresponding position, encoding means converting the x and y co-ordinates of the index position to electrical signals, there being a second table surface parallel to and below the first and a retractable pen mounted on the bug whereby movement of the bug may trace out a representation on the second surface. The position signals are sent to a computer which also controls the pen. Besides cross-hairs, the index has an A.C.-fed coil, the magnetic field from which is sensed by x and y coils on the bug, which also has a relative-position locking coil, or alternatively the coils can be interchanged i.e. the A.C.- fed coil being on the bug &c. The x and y coils control the servomotors so the bug follows the index. When a button on the index is pressed, the position of the bug (and thus of the index) is digitized and sent to the computer. The digitization is done by x and y encoders having input pulleys linked by wires to the bug. Each encoder may be of the optical grating or synchroresolver type, with binary or decimal output, and may count incremental movements in either direction or give an absolute position read-out. The bug holds a rotatable member holding 6 pens with different colour inks, the rotatable member being rotatable using a pawl by pulses from the computer to select a pen, the pen being depressed against a spring by a solenoid-actuated member. The second table surface is under the first which is transparent, or the two are on opposite sides of a single board. The drawing entered into the computer by digitizing successive bug positions as above may be displayed on a CRT which may give a coloured and/or moving display. An overlay may be placed over the first table with positions reserved for selection of corresponding entry points into the computer programme, by positioning the index (and bug) at such positions and pressing the button on the index to enter their positions into the computer. This permits information to be given about the following positions entered, e.g. that they define a straight line or circle to be drawn, or the positions of particular circuit symbols or other standardized items on engineering drawings. It also permits entry of alphanumeric symbols and erasure of parts of the drawing. Such information could alternatively be entered from a keyboard mounted on the index. A pen may be mounted on the index, or a magnifying glass.
