Title: A protective circuit arrangement for a transistor switch
IPC: H02P7/29
Filed: 1959-04-22
Abstract: 902,486. Control of D.C. motors. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. April 22, 1959 [April 25, 1958], No. 13697/59. Class 38 (3). [Also in Groups XXXV and XL (c)] A transistor motor-control circuit comprises means responsive to the transistor current when it exceeds the maximum permissible value to control the input control voltage so as to interrupt the transistor current. The Figure shows a motor 1 and inductor 2 connected in circuit with batteries 5, 6 of opposite polarity and transistors 3 and 4 which are rendered alternately conducting by signals applied to the base electrodes. By varying the on-off ratio of the transistors the mean value of the current applied to the motor can be varied. When the " on " period is relatively long the motor current would build up in accordance with the dotted curve 23 (Fig. 3), to a value above the maximum permissible level 24. To prevent this resistors 10 and 11 are connected in series with the transistors and the voltage across them is applied to bistable circuits 12, 13 which when the resistor voltage exceeds that corresponding to the maximum current, opens the base circuit of the associated transistor. The current then falls from the maximum as indicated by curve 14 until the circuits 12, 13 restores to the original condition so that the mean output current remains at a varying value just below the maximum permissible value. When the motor is being braked it may cause reverse current to flow to the power supply and where rectifiers are used this could damage the power supply system. Accordingly, a supply as shown in Fig. 5, could be used. When reverse current flows the smoothing condenser is charged to a greater value than normal and this value is sufficient when applied through resistor 21 to operate a switching circuit 22 which renders transistor 19 conductive to discharge the capacitor until the voltage is such that tne switching circuit 22 restores to its original condition and cuts transistor 19 off again. It is stated in the Specification that the push-pull circuit arrangement shown in Fig. 1 could be replaced by a transistor bridge circuit.

Abstract: 899,851. Reactor pressure vessels. ATOMENERGI A.B. April 18, 1961 [April 22, 1960], No. 13961/61. Class 39(4). The pressure resistant casing of a nuclear reactor is formed by the walls of a rock chamber in which the reactor is located. The reactor core is mounted within a vessel, the space between the rock and the vessel being liquid filled. The upper part of the vessel is open so that the free liquid surface and the vessel interior are at the same pressure. A rise in pressure within the vessel is thereby communicated directly to the rock through the liquid rather than through the walls of the vessel. As shown, the reactor core 6, within vessel 1, is mounted in rock chamber 7, the water between 1 and the rock walls having a free surface 5. The open top of 1 is enclosed by cover 2 which is attached to the loading machine 15. The latter consists of the adjustable arm 16 supporting a carriage 20 by which the fuel elements may be manipulated. The control rods 11, 17 are adjusted by the devices 13 and 24. Cooling gas enters and leaves through ducts 23, 22 respectively. Leakage of water through the rock is prevented by cement and plastic surfacing. Alternatively, metal sheathing may be applied with a layer of asbestos between the rock and sheathing.

Patent GB-1501239-A (GB)
Title: Cellulose graft copolymer
IPC: C08B15/00
Filed: 1975-04-07
Abstract: The cellulose graft copolymer in fibre form has a cellulose skeleton and, grafted thereto, side chains of polymer radicals obtained from polymerisation with opening of double bonds of olefinically unsaturated monomer molecules; these polymer radicals represent from 10.5 to 90% of the total weight of the cellulose graft copolymer. From 10 to 80% of the total weight of the cellulose graft copolymer comprises ionic monomer units and from 0.5 to 60% of the total weight of the cellulose graft copolymer comprises nonionic monomer units; the individual grafted-on polymer radicals can be those built up only from ionic or only from nonionic monomer units or from both types of monomer units, the only essential feature being that the total amount of ionic and nonionic monomer units in the polymer side chains is in the above-mentioned range. These cellulose graft copolymers in fibre form have fibre properties comparable with those of untreated cellulose, and on the other hand have a very high absorption capacity for water and aqueous liquids. They are therefore very highly suitable as a component of absorbent materials, such as bandage materials, menstrual hygiene materials and nappies (diapers).
