Title: Process for the manufacture of edible collagen casings
Inventor: FAGAN PAUL V
IPC: B29C48/10
Filed: 1968-09-27
Abstract: 1,204,438. Edible collagen tubes. JOHNSON & JOHNSON. 27 Sept., 1968 [27 Sept., 1967; 16 Sept., 1968], No. 46029/68. Heading B5B. [Also in Division C3]  A mass of acid-swollen edible collagen fibrils, which may be plasticized, is extruded in the form of a tube which is inflated with a gas containing ammonia and is subsequently supported until the ammonia has neutralized the acid present and the tensile strength of the tube has increased, the tube then being washed and passed through a plasticizing bath if it was not already plasticized, prior to drying and shirring. The plasticizer may be glycerin and the acid lactic, acetic or hydrochloric. The tube may initially be surrounded by an ammonia-containing atmosphere. A collagen tube containing 10-20% of an edible plasticizer and 1-10% of an edible ammonium salt is claimed per se.

Title: Electronic image device with protective circuit
IPC: H01J29/44
Filed: 1969-09-18
Abstract: 1281208 Cathode-ray tube operating circuits  WESTINGHOUSE ELECTRIC CORP 18 Sept 1969 [30 Oct 1968] 46084/69 Heading H4T [Also in Division H1] A circuit means connected between two electrodes, which are at different potentials, in an electronic image device exhibits the property of a relatively high resistance at and below and a relatively low resistance above such potential difference. The circuit means may comprise a neon lamp, precision spark gaps or back-to-back connected Zener diodes. The invention is described in connection with a protective arrangement for a secondary electron conduction camera tube to prevent damage to the target electrode by the production of an excess potential difference between the target and a closely spaced suppressor mesh electrode. Such excess potential may result when a person or an object having acquired a charge by friction induced static electricity comes into contact with the target lead of the tube, a small charge being sufficient to produce a high potential difference because of the low capacitance between the target and the suppressor mesh electrode. As shown, the tube includes an image section 10 (Fig. 1) comprising an input fibre optics window 18 and a photocathode 20, the photoelectrons produced by which are focused, by the action of an electrostatic lens formed between the surface of cathode 20 and an anode cone 22, on to the target electrode 30. The latter as shown in Fig. 2, comprises a support member 32 formed of aluminium oxide and about 500 Angstroms thick on which a signal electrode comprising a layer 36 of aluminium and also about 500 Angstroms thick is provided. Layer 36 carries a further layer 38 which exhibits the property of secondary electron conduction and is formed as a highly porous layer of potassium chloride about 20,000 Angstroms thick with a density of less than 10% of the bulk density of potassium chloride. A suppressor mesh 46 formed of conductive material having about 10<SP>6</SP> openings per square inch and a thickness of about ¢ mil. and spaced from target 38 by about 0À010 inch is connected to a potential source 52 of about 15V. The signal electrode 36 is connected to a potential source 44 of about 20V and during operation, when the layer 38 is scanned by the electron gun 42 (Fig. 1) to develop video signals (in a resistor connected to electrode 36) the exposed surface of layer 38 is stabilized at approximately ground potential. The circuit means affording the protection for the tube comprising, as shown, a neon lamp 70 connected between the electrodes 36 and 46, may be mounted either internally or externally of the tube.

Abstract: 1527912 Hydrostatic transmission control; resilient couplings INTERNATIONAL HARVESTER CO 12 Nov 1975 [10 Jan 1975] 46714/75 Headings F2W and F2U In a linkage for the control of a hydrostatic transmission a link 16 is coupled to a trunnion shaft 14 of a swash plate 12 of a transmission unit 10 by way of an elastomeric bushing 26 surrounding a sleeve 24 in an aperture 22 of the link, the sleeve being connected to the shaft 14. The elastomeric bushing 26 isolates the linkage from vibration and provides a lag between movement of the link 16 and movement of the shaft 14. The link 16 is pivoted by the engagement of a pin in a slot 40 of a cam plate 42, this being moved by linkwork 46, 48 incorporating ball-joints 50 and 52. A pin 34 interconnecting the sleeve 24 and the shaft 14 extends between a pair of pins 36 to limit the relative movement between the shaft 14 and the link 16 and also ensure that the linkwork will still function if the bushing fails. The elastomeric bushing 26 may be of natural rubber.

Abstract: 1,108,580. Valves. MEYNELL & SONS Ltd. 3 Oct., 1966 [9 Nov., 1965], No. 47391/65. Heading F2V. A valve 16 for controlling the mixing of hot and cold fluids has means to maintain the hot fluid inlet 108 fully closed during initial manipulation of operating means 14 so that discharge of cold fluid always precedes the discharge of heated fluid.

[Also in Division H2] A transformer suitable for high-voltage pulse generation comprises a winding formed by rolling together a conductive foil and an insulating sheet with output connections taken from the foil ends, the winding being immersed in a liquid of high dielectric constant at least ten times that of transformer oil and/or containing an additive to render it slightly conducting in order to reduce the electric field gradients at the foil edges. Suitable liquids are water or glycerine (having dielectric constants of 81 and 56 respectively, compared with about 2.4 for transformer oil). As shown in Fig. 1, an autotransformer wound from copper foil 2 and polyethylene terephthalate sheet 3 is immersed in a dilute solution of copper sulphate in water contained in an annular container 1 of methylmethacrylate, the solution having a resistivity of 20 k# per cm. cube.

Abstract: 1526288 Data transmission; fascimile systems SIEMENS AG 8 Dec 1975 [9 Dec 1974] 50205/75 Heading H4P Signals representing picture elements of a twotone original are obtained by line by line scanning of the original and are run-length encoded prior to transmission. The encoding provides words of three different lengths. An n-bit word is used to represent a string of signals of one tone and an mbit word to represent a string of the other tone. If one such word is insufficient to represent the whole of the length of the relevant string it is supplemented by one or more third words, each of length (m+n) bits, in order to encode the remaining portion. In the embodiments described a line sync. word, consisting of an integral multiple of (m + n) bits, is formed at the start of each line. If a scanned line consists only of one of the tones, e.g. white, only the line sync. word is produced in respect of that line. A simulated white picture element may be encoded at the beginning of the line and a simulated black element at the end of it; these elements are not reproduced at the receiver. Immediately after the line sync word, and after each k(m+n) bits, an address word may be transmitted to indicate the address, relative to the beginning of the line, of a particular picture element, e.g. that at the start of the next black string. The number of bits in an address word is m+r(m+n). The encoding and decoding circuitry is described.
