Patent GB-1475908-A (GB)
Title: Mos circuit
IPC: H03K17/284
Filed: 1974-10-09
Abstract: 1475908 Transistor switching circuits MOTOROLA Inc 9 Oct 1974 [26 Dec 1973] 43769/74 Heading H3T A circuit for providing a signal which charges or discharges nodes of a circuit, e.g. a bi-stable, to establish required initial conditions on switching on comprises: a diode 20 and two MOSFET'S 22, 24 connected in series between supply lines 16, 18 to provide a reference voltage approximately equal in magnitude to the sum of the voltage drops across the diode and MOSFET 24; and a complementary MOS inverter 28, 30 coupled between the supply lines 16, 18 and having its input coupled to the gate and drain of MOSFET 24. The arrangement causes an output V R  to be clamped to a reference level during the time when the voltage across capacitor 32 lies between two limit values. Assuming that the supply voltage V DD  is increasing from zero, then a point will be reached at which diode 20 and FET's 22, 24 conduct to establish a reference voltage across capacitor 32 which turns on FET 28. This results in FET's 36, 40, 48 switching on to clamp output V R  to Ov. As voltage V DD  increases further FET 30 turns on to turn on FET's 34, 42, 44 and turn off FET's 36, 40, 48 so that the output V R  is now clamped to V DD . The circuit may be manually clamped by a signal on line 54 and the automatic clamp may be inhibited by a signal on line 62. Where the clamping to Ov is required for a predetermined time, output V R  may be coupled via a monostable circuit, Fig. 2 (not shown).

Title: Process for concentrating halogenoanthraquinones
IPC: C07C50/18
Filed: 1975-10-24
Abstract: By means of a single- or multi-stage fractional vacuum distillation, individual haloanthraquinones and/or binary di- and/or trihaloanthraquinone mixtures are concentrated from haloanthraquinone mixtures, after a possible removal of non-volatile impurities. In this process, the mixtures are preferably distilled in a heated rectifier column having an efficacy of 20 to 50 theoretical plates, under a vacuum of 5 to 25 mm Hg and at a reflux ratio of 5:1 to 50:1.   By means of the process, important starting materials for dyestuff syntheses are made available again in high purity from hitherto worthless waste products.

Abstract: 1312998 Paper making CENTRE TECHNIQUE DE L'INDUSTRIE DES PAPIERS CARTONS ET CELLULOSES 15 Sept 1970 [18 Sept 1969] 44001/70 Heading D2A A sheet or web is formed by bringing a liquid containing elongate particles into contact with a travelling band by overflow of the liquid from a container, and imparting to the particles in the liquid adjacent the band a velocity having a component generally parallel to the surface of the band and perpendicular to the direction of movement of the band whereby the particles are orientated obliquely relative to said direction of movement. The band 4 may be of fine-mesh metal cloth and extends over driven rollers 5. It may be other than vertical as shown. The container 6 is continuously supplied with pulp by a pump 9 and the liquid in the container is rotated by a bladed rotary agitator 10, the speed of which can be varied. The liquid overflows through a slot 17 having a doctor seal 18, e.g. of plastics material. Liquid passes through the band into a chamber 22 which may be subject to suction. In a second embodiment, Fig. 4 (not shown), two webs or sheets are formed on bands passing on either side of the container, the bands being curved round the cylindrical body of the container and being surrounded by an annular chamber to which liquid passes through the bands. After passing the container, the bands resume their flat shape and are passed round guide rollers whereby one of the formed webs or sheets is disposed on the other, the particles in one web or sheet being orientated in a different direction to those in the other, Fig. 5 (not shown). More than two webs or sheets may be formed simultaneously. In a modification the pulp is supplied tangentially to the container whereby the agitator 10 may be omitted.

Filed: 1970-09-17
Abstract: 1282668 Pulse regenerators NIPPON ELECTRIC CO Ltd 17 Sept 1970 [20 Sept 1969] 44483/70 Heading H3T In a pulse regenerator comprising a bi-stable circuit which in its set state operates a switch to pass current through an output transformer, a timing circuit is provided to switch off the current if the bi-stable circuit remains in the set state too long, e.g. due to interference pulses or because the bi-stable switches to the set state upon first switching on. Fig. 5 shows a bi-polar pulse regenerator formed from Nor gates and comprising two bi-stable circuits 1, 1<SP>1</SP> having set inputs 11, 11<SP>1</SP> and reset inputs 12. When either is in the set state current is applied to the corresponding side of the output transformer and, via gates 613 and 611 or 612, the timing circuit 62, 63 is enabled. If the bi-stable is not reset by the input signal in a given time the capacitor will recharge sufficiently to effect reset. The output circuit is thus protected against excessive current rise. In Fig. 6 (not shown) a diode-transistor Nand logic is used and in a similar circuit (Fig. 7, not shown) the bi-stable is not reset but the timing circuit interrupts the output current directly.

Abstract: 1,261,423. Degreasing apparatus. UDDEHOLMS A.B. Sept.16, 1969 [Feb.4, 1969], No.45634/69. Heading C7E. Artreles 12 on a perforated base 4, which may be a roller conveyer, are degreased by boiling a solvent in a chamber 2, causing the vapour to condense on the articles and run back into the chamber with dissolved grease. When the articles have reached the temperature of the vapour, a thermostat 21 opens a valve 19 to cause cooling water to flow through pipes 16 which causes solvent vapour to condense and flow down on to the articles to give them a further cleaning. A timer 22 then emits a signal to close the valve 19, and start a motor 7 to lift the lid 11 from the articles. Movement of the lid trips a switch 27 to cause cooling liquid to be supplied to a wall 9a of a liquid lock to condense solvent vapour, and lower the level of the vapour to openings 10. Air is drawn in through a pipe 29. When the lid clears the articles, they are removed and replaced by further articles, the lid being lowered and the cycle restacted. In a modification, Fig. 2 (not shown) instead of supplying coolant to the wall 9a a cooler is provided in the chamber beneath the base 4, and the solvent is pumped through spray nozzles located above the articles. The top of the lid 11 is provided with an active carbon filter, which may be cleaned by steam, and a ventilation drum surrounds the liquid lock at the bottom of the lid. In both modifications the spraying device may be fixed to the top of the lid. The lid may also operate a switch to ensure that the solvent heater is only operated when the lid is in position.
