Title: Method of preparation of hydrophilic spongeous gels
IPC: C08F8/00
Filed: 1973-08-07
Abstract: 1422855 Implantable prosthesetic tissue: surgical drains CESKOSLOVENSKA AKADEMIE VED 7 Aug 1973 [15 Feb 1973] 37429/ 73 Heading ASR [Also in Division C3] In Example 1 a spongey implantable prosthesis which allows growth of tissue through the pores thereof is prepared by mixing a nitric acid solution of a hydrophilic polymer (see Division C3) with urea nitrate crystals. The mixture may be shaped in a 1:5 mm gap between a concave matrix and a convex patrix to provide a spherical cap for covering a denuded joint of inner radius 15 mm and sagittal depth 32 mm with a thickened edge, removing the patrix, coagulating the shaped material by immersion in water, removing the matrix and washing the shaped article in lukewarm water to extract the urea mononitrate and finally sterilizing the resulting cellular material by boiling in physiological solution. In Example 3 a similar mixture is used for a mammary prosthesis: In Example 4 a similar starting mixture is rolled into a sheet, washed and coagulated in water to form an elastic spongeous plate, cut to size, soaked in an antibiotic, cancerostatic or cytostatic drug, further dipped in the original homogeneous starting polymer solution and subsequently treated with sterile water to develop a thin hydrogel layer on the surface which is capable of allowing controlled difusion of the incorporated drug. The result is a material useful as a temporary body implant which swells and releases the drug after implantation. As alternatives the implant material may be sealed in a sterile polypropylene capsule or may be dried and sterilized with ionizing radiation for subsequent application in the dried state. In Example 6 a polymer solution as in Example 1 is extruded into 2 mm sticks of 25 cm length coated with homogeneous starting copolymer solution and subsequently coagulated and rendered porous by washing with water and sterilizing in boiling water. Both ends of each stick are cut off to expose the porous core and to provide a material suitable for draining a superfluous cerrebo-spinal humour from intracranium to vend cava in hydrocephalic patients.

In a flat bed knitting machine in which needles 3 are taken out of action at each end during the narrowing process the needles are controlled by slides 8 in the needle slots 1. These slides are all pivoted about a fulcrum wire 11 and are adapted to be moved longitudinally, with a projection 16 engaging in either of recesses 12, 13, 14, by means of combined cam and worm members 18-20 at each end of the machine. These members are slidable along a square section bar 17 when the latter is rotated by reason of the thread of the worm 18 engaging between hooked end portions 10 of the slides 8. The cam portions 20, 19 are adapted to move the slides 8 succesively from a forward position A, Fig. 3, to an intermediate position B and then to a withdrawn position C or vice versa according to the direction of rotation of the bar 17 at the positions A and B the slides 8 are not operated to affect the needles but in the position C, with the projections 16 in recesses 14, butts 9 on the slides are engaged by a cam bar on the cam box carriage to depress the needles 3 into their slots against springs 7. The butts 4 of these needles 3 are thereby removed from engagement by the knitting cam and such needles are out of action. The worms 18 at the respective ends of the machine are of different hand so that needles are taken out or brought into action at both ends together for narrowing and widening respectively. Another cam bar is adapted to engage the butts 9 of the slides 8 in position A so that only the needles of the slides in position B are engaged by the narrowing cam box when allowed by retraction of a third cam bar as required. Three cam bars are also provided for the knitting cam one of which is fixed and engages butts 9 of slides 8 in position C whilst the other two are movable into engagement as required for patterning effects.

Abstract: 896,123. Cathode-ray tubes. GENERAL ELECTRIC CO. Ltd. Oct. 14. 1960 [Nov. 5, 1959], No. 37624/59. Class 39(1). A cathode-ray tube designed to operate with post-deflection acceleration of the electron beam comprises an electrically-conducting mesh electrode 14 in the vicinity of, and parallel to, an electrically-conducting target screen 8, the surface of the mesh 14 remote from the screen being coated with a layer of dielectric material 16 whose secondary electron emission properties are such that the layer is charged positively with respect to the mesh in normal use of the tube, whereby electric fields are formed within the meshes of electrode 14 which prevent the low velocity secondary electrons from passing through to screen 8. A hollow, open-ended, conducting shield 18 of appreciable axial length is disposed on the side of the mesh 14 remote from the screen, with one end adjacent to but insulated from the mesh, which extends radially outwards beyond the adjacent end of the shield around the whole of its periphery. As shown, the metallic wire mesh 14 is carried by a frame 15 which is spaced from shield 18 by insulating supports 20, and which is provided with an external contact 17 whereby the mesh is maintained at a potential slightly, e.g. 50 V, negative with respect to shield 18. The shield 18 may be frusto-conical instead of cylindrical and may contact the tube wall by means of a radial flange instead of being secured thereto by members 19 as shown, but is in each case maintained at the same potential, e.g. 1 kV positive with respect to the cathode, as the final anode 11 of gun 5 by means of a graphite or silver wall coating 10. The conducting layer 8 on luminescent layer 6 is 10 kV positive with respect to the cathode and is connected to coating 10 by a resistive coating 13 of chromic oxide. The dielectric layer 16 may be of silica, alumina or magnesia and during operation is maintained approximately at the potential of shield 18. The phosphor layer 6 may be replaced by three superposed transparent phosphor layers which emit in different colours with or without intermediate transparent layers of electron energy absorbing material. Voltage colour signals from a colour synchronizer circuit are applied to the aluminium film 8 to cause the electron beam to penetrate to each of the phosphor layers in an appropriate sequence. Specification 896,122 is referred to.

Title: Transistor oscillator surge protection circuits
IPC: H02M7/5383
Filed: 1962-10-12
Abstract: 1,025,482. Transistor inverter circuits. GLOBE INDUSTRIES Inc. Oct. 12, 1962 [Oct. 23, 1961], No. 38806/62. Heading H3T. [Also in Divisions G3 and H2] A transistor inverter of the type including a pair of push-pull transistors connected in common emitter configuration, an output transformer and a feedback transformer, is provided with a surge protection circuit connected between the common emitters and a tapping on the primary winding of the output transformer and comprising a power source connected in series with the emitter-collector path of a third transistor, biasing means for the base of the third transistor, and means controlled by the third transistor for determining the loading of the feedback transformer. As shown in Fig. 1, push-pull arranged transistors 10, 12 feed an output transformer 24 and oscillations are sustained by means of feedback resistor 34 and transformer 32, a starting network comprising resistors 50, 52 being provided between centre taps 40, 20 of transformers 32, 24. The power from battery 18 is supplied to the inverter through a surge protection circuit comprising the emitter-collector path of transistor 60 which during normal operation is saturated by a signal taken from output transformer 24, rectified by diodes 64, 66 and applied to the base of transistor 60. The bias of the base of transistor 60 is clamped by Zener diode 72 which will prevent transistor 60 from passing voltages of levels higher than its breakdown level. If a moderate surge appears on the power drive, the drive to transistors 10, 12 is reduced and in the event of a large surge the drive to transistors 10, 12 is eliminated and the inverter is shut down. The circuit also includes a loading winding 74 on the feedback transformer 32 the output from which is rectified by diodes 70, 78 and applied to transistor 80 the base bias of which is derived from transistor 60. When transistor 60 is saturated under normal conditions transistor 80 is reverse biased by the voltage developed across resistor 104 and thus presents no load to transformer 32. When a surge appears on the power line transistor 60 is reverse biased and the same reverse voltage appears as a forward bias through resistor 86 to transistor 80 reducing the collector to emitter impedance of this transistor and loading transformer 32. This latter action reduces the drive necessary to transistors 10, 12. Zener diode 90 is arranged so that above a given level transistor 80 saturates immediately and shuts down the inverter. In the circuit of Fig. 2 the bias of transistor 60 is derived from an error detector. The output voltage between 110 and 112 is sensed across variable resistor 100 and compared with the standard voltage generated across the Zener diode 103, the difference between these voltages being amplified in transistors 101, 105 and used to bias transistor 60. The arrangement is such that the emitter collector impedance of transistor 60 is increased when the power supply increases.
