Title: Urea and thiourea derivatives
Inventor: JULIA MARC
IPC: C07C275/42
Filed: 1966-06-07
Abstract: Novel urea and thiourea derivatives of Formula I <FORM:1110099/C2/1> wherein X is oxygen or sulphur, A is a straight or branched alkylene group having 1-4 carbon atoms, the groups -NH- and -CO-attached to a common benzene nucleus are in meta or para position in relation to one another, R and R1 are hydrogen or methyl, and the groupings -NH- and -CH3 attached to a common benzene nucleus are in ortho position in relation to one another, and acid addition salts thereof, are prepared by reacting two moles of an amino-amidine of Formula II <FORM:1110099/C2/2> or an acid addition salt thereof, with one mole of carbonyldiimidazole or thiocarbonyldiimidazole, with or without an inert and anhydrous organic solvent at a temperature between ambient and 120 DEG  C., or by reacting one mole of a 1,3-bis-(3-chlorocarbonylphenyl)-urea or -thiourea with two moles of an aminoamidine of formula <FORM:1110099/C2/3> and, in each case, optionally converting the product obtained into an acid addition salt.  The starting materials of Formula II may be prepared by the series of reactions shown in the following reaction scheme: <FORM:1110099/C2/4> The bis(3-chlorocarbonylphenyl)-ureas or thioureas may be prepared by treating the corresponding diacid obtained by reacting amino-benzoic acid with urea, with thionyl chloride.  The amidines of Formula II may also be prepared by treating a (nitrobenzamido)-benzoic acid with thionyl chloride, reacting the acid chloride with an aminonitrile, treating the [(nitrobenzamido)-benzamido]-nitrile with dry gaseous hydrogen chloride in chloroform/ethanol, isolating the imino-ether hydrochloride and treating this with anhydrous ammonia at 0 DEG  C. to give the [(nitrobenzamido)benzamido]-amidine which is then hydrogenated.  Therapeutic compositions having anti-viral and hepatoprotective activity, which may be administered parenterally, or orally, contain as active ingredient at least one compound of Formula I above or a non-toxic acid addition salt thereof.

Title: Improvements in or relating to driers and process for operating same
IPC: F26B21/04
Filed: 1929-08-20
Abstract: 338,585. White, A. E., (Coc Manufacturing Co.). Aug. 20, 1929. Valves controlled by pilot or relay valves. - In a method of drying in a drier operating above 212‹ F. the moisture content of the drying medium is automatically controlled by an arrangement which includes an instrument box cooled below 212‹ F. and containing valve-controlled mechanism. Part of the drying medium circulating in a casing 10, Fig. 1, and a conduit 18 is shunted through the instrument box 27 and conductors 28, 29, the rate of flow being automatically controlled through a damper 33. In the box, dry and wet bulb thermometers 44 and 45, Fig. 5, operate in conjunction with valves contained in casings 46, 46<1>. The valves have each a double-ended valve-piece 53 with an axial drilled opening communicating through bellows 55 with an open-ended tube 56 or 56<1>. The dry bulb thermometer operates to maintain a predetermined constant temperature in the box. With temperature changes, the cell 44 expands or contracts and this opens or closes tube 56<1>. This determines whether the valve 46' shall allow compressed air to pass by way of tubes 52 and 74 into a diaphragm motor 7 or to be exhausted into the atmosphere. When compressed air passes into the motor 7, it brings a damper 32 in conductor 29 towards the closed position, thus cutting off the supply of hot medium into the box. The wet bulb thermometer measures the moisture content of the medium and automatically controls it, and when it exceeds that for which the control is set moisture is deposited on the bulb, causing it to expand. This causes valve 46 to let compressed air by ways of tubes 52, 73 into a diaphragm motor 8, causing a damper 39 to move towards the open position, thus discharging used medium through a stack 22 into the air. This discharged medium is replaced by fresh medium at the ends of the casing. Gauge hands 64, 69 register the temperature of the bulbs 45, 44.

Title: Time base, rectifier and like high voltage electrical circuits
Inventor: MACLEOD KENNETH CHARLES
IPC: H02M7/10
Filed: 1951-11-02
Abstract: 713,096. Rectifying CINEMA-TELEVISION, Ltd. April 18, 1952 [Nov. 2, 1951], No. 25648/51. Class 38(2) In a thermionic valve rectifier circuit in which during operation the cathode heater or filament of the rectifier is subjected to a high voltage with respect to earth the heater or filament is supplied with alternating current by way of two conductors which together form a transformer winding in which the high voltage is generated. Fig. 2 shows a voltage double rectifier circuit for producing a high D.C. voltage at point 7 from a low voltage source 1 of high frequency alternating current. The filament of rectifier 5 is prevented from attaining a high voltage comprising the superimposed A.C. voltage appearing across the secondary winding of transformer 2 and one-half the D.C. output voltage by the use of a double secondary winding on transformer 2 to supply the primary winding of filament transformer 9. By this means the whole of transformer 9 is maintained at the full A.C voltage of the secondary of transformer 2 with respect to earth so that the inter-winding insulation of transformer 9 is no longer subjected to alternating potential. The transformer 2 is preferably of the type described in Specification 695,222. Fig. 3 shows a voltage quadrupler rectifier circuit having a double wound secondary winding to transformer 2 similar to that described in connection with Fig. 2.

Title: Improvements in circuit arrangements adapted to produce electric current impulses ofpredetermined duration
IPC: H04M19/02
Filed: 1937-09-22
Abstract: 487,563. Electromagnetic relays. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 22, 1937, No. 25737. Convention date, Sept. 25, 1936. [Class 38 (v)] When a switch 16 is closed, a circuit is completed to a resistance 18 which changes its resistance as it becomes hot thereby increasing the voltage applied to a relay 17 with the consequent actuation of the relay a predetermined time after the closure of the switch 16. The invention is shown applied to a spotwelding system, the bringing of the electrodes into contact with the work serving to close the switch 16 and thereby complete a circuit 23, 24, 25, 26 to the primary of a transformer 11, the secondary of which supplies current to the electrodes 10. The resistance 18 and relay 17 are arranged as shown, and the increase of the resistance 18 with rise of temperature causes a drop of potential across an adjustable resistance 19 and a consequent increase of potential across the relay 17. The relay 17 thereupon attracts its armature 20 which by impact opens contacts 14 and breaks the transformer circuit. In a modification, Fig. 2 (not shown), the resistance 18 has a negative temperature coefficient. The resistances 18 may be lamps with tungsten or carbon filaments or they may be of molybdenum or tantalum.

Filed: 1973-06-01
Abstract: 1477461 Offshore structures KING-WILKINSON Ltd 30 May 1974 [1 June 1973] 26347/73 Heading E1H An offshore structure, e.g. a petroleum exploration or production platform, or an oil tanker mooring, has at least five columns (preferably eight or ten) which diverge and slope outwardly and downwardly to meet the corners of a polygonal tubular base member 1. Bracings 7a, 7b &c between adjacent columns 2 are arranged in zig-zag formation with the junctions on opposite sides of the same column in register. At each junction two bracings meet on each side of the column and at the same angles to the column, thus facilitating production. The top frame 3 has bracings 5, 6, and the tower may also be stiffened by horizontal lattice frames 9, 10. The base 1 may have water jet nozzles to facilitate its settling on the sea bed, and laterally extending plates to give a greater support area and reduce scouring (Fig. 6, not shown). The tower may also be located on the sea bed by piles driven through guide tubes fixed by brackets to lie parallel to the columns 2 (Fig. 5, not shown). The structure may be built in an area excavated to match the shape of the tower (Fig. 8, not shown), or in a dock, or on a slipway. The top frame 3 and base 1 may be fabricated first and the columns and bracings inserted later, preferably using pre-fabricated units comprising a pair of columns and the bracings between them. As shown in Fig. 16, the columns and bracings I-II and V-VI are fitted, then the structure is rotated with the base floating in water in the dock 72, and other units are fitted until the structure is complete as in Fig. 20. Alternatively the structure is fabricated from a series of units each consisting of a frame 81, or base, or horizontal lattice frame 83 (Fig. 21), each with portions of the columns and their bracings. These units may be assembled on a slipway as in Fig. 21, or by adding units successively to the base in its correct orientation. In this case, the base is sunk as assembly proceeds (Fig. 25, not shown).
