Title: Compound having the formula pnscl and process for preparing same
IPC: C01B21/097
Filed: 1963-02-15
Abstract: The compound P2NSCl5 is prepared by reacting P3NCl12 with at least stoichiometric amount of (a) gaseous H2S, or (b) a mixture of S and sulphur monochloride, and recovering the product, e.g. by fractional vacuum distillation. Reaction (b) is effected by dissolving P3NCl12 in an inert solvent, e.g. symmetrical tetrachloroethane, nitrobenzene, nitromethane, sulphur monochloride or acetonitrile; suspending at least a stoichiometric amount of sulphur, and adding sulphur monochloride (except when it is the solvent).  Reactions may be carried out at room temperature and pressure, but (b) is accelerated by heating to 150-160 DEG  C.ALSO:The compound R3P:N.P(S)R2, where R is dimethylamino, is obtained by reacting dimethylamine with Cl3P:N.P(S)Cl2 (see Division C1). It is an active insecticide.

Title: Improvements in or relating to beating engines for making paper pulp
IPC: D21D1/02
Filed: 1922-03-02
Abstract: 194,132. Smith, S. March 2, 1922. Pulping-engines.-Relates to pulping-engines having two or more bed plates and comprises the provision between any two plates of a recess which is open towards the cylinder bars and in which an agitation of the pulp is produced whereby the fibres covering the cylinder bars during motion over the plate are continuously replaced. In one arrangement a diaphragm h, Fig. 5, secured by a plate k to a beam j is pulsated vertically by a connecting-rod or similar mechanism, or by a pulsating gas or liquid medium. In one modification, agitating-vanes e, Fig. 6, on a rotating shaft m are employed, and in another modification compressed air is admitted through the floor of the recess to agitate the pulp. Mechanical means may be dispensed with if the bottom of the recess p is shaped as shown in Fig. 8 to produce a discharge of the pulp from the cylinder cells during the first portion of the forward motion, and a subsequent supply as the cells approach the second bed plate.

Abstract: 957,618. Moulding last blocks. LESLYNN PRODUCTS CORPORATION. Feb. 21, 1961 [June 27, 1960], No. 6357/61. Heading B5A. A last block, that is a block which conforms roughly in shape and size to a shoe last, free from internal voids comprises a body of highdensity polyethylene having a specific gravity of at least 0.945. The last block is formed by introducing the polyethylene in a molten state into a mould and slowly cooling the mass so produced. In the method described, when the polyethylene is introduced into the mould a thin skin is formed thereabout by contact with the cool surface of the mould so that the polyethylene mass may be taken out of the mould and placed in a heat insulated enclosure, the container being at a temperature of 5‹ to 10‹ C. above the crystallization point of the polyethylene. The preferable cooling time is from 6 to 10 hours.

Abstract: 650,976. Drum brake. DUNLOP RUBBER CO., Ltd., and BUTLER, H. J. March 6, 1948, Nos. 6970 and 29872. [Class 103 (i)] A drum brake, particularly for light aircraft, autogiros and the like, comprises a pair of equal diameter coaxial drums 6 and 7, Fig. 1, which are mounted to rotate with the wheel hub 1 and are gripped by inner and outer brake blocks 16 and 17 interconnected by the rod 24 of a fluidpressure actuated piston 23, movable in a cylinder 21 secured to a spider member 12, 13 bolted to the fixed axle 3. As shown in Fig. 2, the spider member has radial slots 15 in its outer periphery which serve to guide the movement of the blocks 16, 17. The rod 24, which passes between the drums 16, 17 has secured to its end a spherical face nut 26 which in combination with the spherical bearing surface 20 of the cylinder 21 allows the blocks 16, 17 to rock sufficiently to adjust themselves to irregularities in the drum surface. In a modification, there is only a single brake drum and the force from the internallymounted fluid-pressure actuator is transmitted to the outer brake shoe by means of a U- shaped member extending around the rim of the drum. The actuator may be such as that described in Specifications 631,880 and 641,665.

Abstract: 1408126 Fluid-pressure servomotor systems; automatic control VEREINIGTE FLUGTECHNISCHE WERKE-FOKKER GmbH 15 Feb 1974 [30 March 1973] 7040/74 Headings G3N and G3P  A redundant control arrangement, e.g. for the nozzles 31 or control surfaces 33 of a V TOL aircraft, comprises main servomotor systems 14, 15 and a standby servomotor system 16 which is switched in when monitoring means detects failure of both the main systems. Each of the latter comprises an hydraulic servomotor 22 positioned by a pilot valve 21 responsive to the electric output signal of an amplifier 20 receiving inputs from a triplicated flight control 13 operated by a control column actuated potentiometer 11, and from network 24 of a feedback potentiometer 23. Flight control 13 controls analogue monitoring circuits 17, 18, associated with main systems 14, 15, which transmit signals to comparators 36, 37 also receiving signals from potentiometers 23. Normally there is no output from either comparator 36 or 37, but should, say, main system 14 fail then comparator 36 transmits a signal to open by-pass valve 25 of that system thus connecting opposite sides of the servomotor piston to cut-out the system 14 whilst system 15 remains in operation with the hitherto freely pivotal balance beam 27 locked to prevent pivoting. Should both systems 14, 15 fail and be cut out, the signals from comparators 36, 37 are also transmitted via an AND gate 38 to cause closing of the normally open bypass valve 41 of the standby system 16 so as to bring the latter into operation, powered by an emergency hydraulic supply. Simultaneously an optional coupling 28 in the transmission between systems 14, 15 and nozzles 31 or control surfaces 33 is disconnected so that movement of the latter is effected via rod 30. In a modification, by-pass valve 41 is replaced by a normally disconnected coupling 40 which is made rigid when standby system 16 is switched in.

Convention date, June 29, 1931. [Class 81 (ii).] In a blood-transfusion apparatus consisting of a syringe 13 and a distributor 1, the latter is provided with a slide valve 7, and the force required to move this in its body portion is less than that required to move the piston of the syringe in the syringe barrel, so that when the distributor is held with one hand, and the syringe plunger with the other, and pumping is effected in the usual manner, the initial operation in either direction serves to move the slide valve and thereby to cause one or the other end of the transverse passage 10 to register with the suction or delivery pipe 2, 3. The syringe is detachably connected to the passage 10 through passage 11. The traverse of the slide valve is limited by studs 8 working in bayonet slots 4. One such stud and bayonet slot may be employed. A conduit similar to conduits 2, 3 may be mounted at right angles thereto, and by turning the valve 7 to bring one end of the transverse passage into engagement therewith, the apparatus may be washed out. An arrow indicating the direction of flow of the blood may be engraved upon the body portion of the distributor.

Filed: 1965-02-19
Abstract: 3-Methoxybenzanthrone is purified by successive recrystallizations from different solvents, e.g. xylene, acetic acid or benzene, to yield a yellow luminophore with emission maxima at 540 and 580 mm . It may be used, in agar-agar, for marking sand, in enamels, inks, oil colours &c., or as a pigment in solid solution in a melamine toluenesulphonamide - formaldehyde resin, or in detecting defects. In an example, the dye was first dissolved in xylene and activated carbon and aluminium oxide added.  The mixture was boiled and filtered.  The precipitate was then recrystallized from pure acetic acid containing activated carbon.  Finally, the crystals were again recrystallized in benzene and aluminium oxide.
