Title: Electrothermographic reproduction process
IPC: G03G13/04
Filed: 1961-02-10
Abstract: 914,864. Electrothermographic copying. KALLE A.G. Feb. 10, 1961 [Feb. 13, 1960], No. 5103/61. Class 98 (2). [Also in Groups VIII and XXXVI] Contact prints of an original are made by reflex exposure to infra-red radiation of a copying material transparent to infra-red and comprising a conducting support carrying a charged electrothermographic layer disposed so that the charged layer is remote from the original, and thereafter developing and fixing the electrostatic image produced. Charging may be effected either before or after applying the copying material to the original. The copying material may be a sheet of paper, cellulose, cellulose ester, polyester, polyamide, or urethane, carbonate or vinyl polymers coated with as electrothermographic layer a mixed polyester of iso- and tere-phthalic acids with ethylene glycol, polystyrene, polyvinyl chloride, chlorinated polyvinyl chloride, polyvinyl acetate or chloride-acetate, vinyl chloride-butadiene copolymers, chlorinated rubber, maleinate resins, ketone resins, phthalate resins, colophony, abietic acid ester of pentaerythritol, coumarone resins, or dimerized abietic acid. Alternatively the copying material may have an identical coating on each face of the support to prevent curling and either face of the material, which when charged bears opposite charges on the two outer layers, may be developed and fixed to form the copy. A suitable powder developer consists of a glass ball carrier and a positivelycharged resin powder formed by melting equal weights of polystyrene and a resin-modified maleic acid resin together with a minor proportion of carbon black and grinding the solidified melt.

Title: Polymer entrapped or encapsulated enzyme compositions
IPC: B01D71/40
Filed: 1973-02-01
Abstract: 1415597 Reactions with absorbed enzymes NATIONAL PATENT DEVELOPMENT CORP 1 Feb 1973 [11 Feb 1972] 5197/73 Heading B1X [Also in Divisions C3 and G1] A process for subjecting a substrate e.g. blood or body fluid containing an enzymesusceptible material to the action of an enzyme comprises permitting the enzyme-susceptible material of the substrate to come into contact with the enzyme entrapped or encapsulated within a water-insoluble hydrophilic polymer of a monomer of the group consisting of hydroxy lower alkyl (i.e. C 1 -C 3 ) acrylates, hydroxy lower alkyl methacrylates, hydroxy lower alkoxy lower alkyl acrylates, hydroxy lower alkoxy lower alkyl methacrylates with or without a proportion of vinyl pyrrolidone, acrylamide, methacrylamide, N- lower alkyl acrylamide, N-lower alkyl methacrylamide, N-hydroxy lower alkyl acrylamide, and N-hydroxy lower alkyl methacrylamide. The water insoluble hydrophilic polymer may be in the form of a hollow tube having a relatively thin overall internal semipermeable membrane coating of a polymer as above, but enzyme free, the semi-permeable membrane being permeable to the enzyme-susceptible material but not to the enzyme. In Fig. 3 a tube 18, shown in crosssection, comprises a lumen 20, a urease containing polymer layer 22 containing a reinforcing sheathing of polyethylene terephthalate and, optionally, inner and outer coatings of water insoluble hydroxyethyl methacrylate polymer. When a solution of urea is forced through the lumen of the tube the solution diffuses to the enzyme entrapped tube and ammonia diffuses out of the outer surface of the tube thus enabling the purification of body fluids e.g. blood to eliminate urea.

[Also in Division H4] In an assembly and aerial cross arm member 26 and a strengthening member 27 are secured together by a clamp comprising two jaws 1, 2 and means 24 for moving the jaws in and out of clamping engagement with and transversely of the strengthening member and cross arm member each jaw being provided with a tongue 12, inclined interiorly of the clamp, each so as to engage respective apertures on arms of the members when said member is between the jaws, the tongue of one jaw being arranged to act in the opposite direction to the tongue of the other jaw when the tongues engage their respective apertures. As shown the jaws are made from identical stampings, but the jaw 2 has a threaded bush 11 which is engageable with an aperture in the stamping so that means 24, which is a threaded bolt, can engage the bush to move the jaws towards each other. The bolt passes through the aperture in the other jaw. Each jaw is provided with side lugs to keep the two members spaced and end lugs which engage the outside faces of the two members. The jaws are thus adapted to grip members of square or rectangular crosssections but in a modification they can be designed to grip members of other crosssectional shape. The two members shown are part of a band IV or V television aerial.

Abstract: 1433672 Data transmission; master and slave systems SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 6 Feb 1974 [8 Feb 1973] 05522/74 Heading H4P In a system comprising, say, a number of branch stations operating to a central station but with selective access required to other subscribers, to reduce the number of lines and provide access to a switched, e.g. public network a number of first concentration/expansion (C/E) units are provided in various service areas having inputs characteristic of individual users the units having junction lines less than the number of users connected to each respective unit, extending to nodes for switching traffic, and second C/E units in the nodes having the same number of inputs and outputs as the first units and connected through the lines to first units so that connection between a given input of a first unit and a selected line causes a corresponding 1/1 output from the second unit. A third C/E unit in the node controls traffic of lines having a "permanent" connection to a data routing and/or process centre. A set of connections in a node permanently connect a given output of a given 2nd C/E unit characteristic of a particular user directly to another user or to the input of another second or third C/E unit to which traffic from the first user is destined. Request for connection from a subscriber say 1 connected to C/E unit CE1 is registered by a marker unit M1 which selects a free line, if available, in channel FL1 and transmits indications to C/E unit CE1, and if address is to processing centre R/ED1, CE1 connects to output 1; passage may be through another pair of C/E units to the centre or through a single unit such as CE (D1). In a node, e.g. N1 some outputs may be connected to different routes through further C/E units, e.g. CE6/CE6<SP>1</SP>. In a further arrangement, access may be made to a switching, e.g. public, network through a selective C/E unit (CE5<SP>0</SP>) (Fig. 2, not shown) connected to an automatic exchange (AU). One form of marker is described in connection with Fig. 4 (not shown) which includes a set of translators developing control signals which are exchanged between corresponding pairs of markers along a common signalling line, e.g. LC1.

Abstract: 1,121,381. Puffed starchy products. SPROUT, WALDRON & CO. Inc. 10 Feb., 1966, No. 5979/66. Headings A2B and A2Q. In continuously producing puffed pellets of cereal materials or other starchy products such as potatoes for animal or human consumption, the cereal material is fed by means 20 to a pressure cooking unit 22 supplied with steam and maintained at superatmospheric pressure, the cooked material is passed to an extruding assembly 24 and extruded into atmospheric pressure, and the extruded material is cut into pellets. In the feeding means the material is fed by a screw feed 36 along a section 35 at the end of which is a rotatable axially movable member 37. This member 37 is kept in its closed position till a plug of material sufficient to prevent loss of pressure from cooking unit 22 when member 37 is moved to its open position, is formed against it. When in its open position member 37 is rotated to break the inner end of the plug material into fragments which fall into cooking unit 22 along which the material is conveyed by rotating paddles 95 to extruder 24. In extruder 24 the cooked material is screw fed to the plate 140 having the extrusion orifices 141 such that a plug of material is built up against the extrusion plate to prevent loss of pressure in the cooking unit and extruder, as the material is extruded throught the orifices 141. The extruded material is cut by wires 145 mounted between rotating cones 146, 147. One end of casing 106 of cooking unit 22 may be hinged to the body of the casing 106 such that it can be opened if desired.
