Abstract: 1402168 Semi-conductor A.C. switching circuits INTERNATIONAL RECTIFIER CORP 1 Nov 1972 [1 Nov 1971] 50319/72 Heading H3T A firing circuit 26 derives its power by rectifying A.C. at 10, 11 and in response to an optical input 34-33 fires the S.C.R. 23 (24) at or near a zero-cross over of the A.C. supply. The S.C.R.'s 23, 24 supply a load 21 across the A.C. supply (a triac may be used, Fig. 3, not shown). A full wave rectifier 17, 18, 19, 20 supply D.C. to the firing circuit 26 which in the absence of an optical input has T30 off, T31 on, and an S.C.R. 25 therefore off because its gate and cathode are connected by T31. An optical input turns T30 on and T31 off, enabling S.C.R. 25 to fire when a third transistor T32 goes off and releases its gate. Turn-off of T32 is arranged to occur, by choice of R44, R45 when the rectified A.C. has reached a low enough value. Conduction of S.C.R. 25 shorts the D.C terminals of the full wave bridge rectifier and produces increased currents in resistors 21, 22 during respective half-cycles. S.C.R.'s 23, 24 are thus fired.

Title: Improvements in and relating to the manufacture of filter elements
Inventor: STEVENSON PETER ALAN
IPC: A24D3/10
Filed: 1964-12-14
Abstract: Cellular rods of regenerated cellulose are produced by forming a mixture of (a) a viscose having a ball-fall viscosity of at least 150 seconds and a salt point of at least 15; (b) a water-soluble salt which forms an alkaline solution in water, of average particle diameter less than 600 microns, the ratio of salt to viscose being at least 3:1 by weight; (c) at least 80% by weight of the cellulose in the viscose of a water-insoluble particulate filler; extruding the mixture through a die into an alkaline bath saturated with the ions of the water-soluble salt and at a temperature higher than 90 DEG  C. to form a rod, removing the rod from the bath when regeneration of the cellulose is substantially complete, and bringing the rod into contact with water to dissolve the salt particles.  The preferred water-soluble salt is trisodium phosphate, and the insoluble filler may be short fibres, fibrilar particles such as wood pulp, or an adsorbent, e.g. activated charcoal, alumina, magnesia, clays or zeolites, fuller's earth, bauxite or ion-exchange resins. Suitably the viscose has a viscosity of about 700 seconds and a salt point of 20, and the extrusion is done by means of a screw extruder.  The water used for leaching out the salt particles is suitably at a temperature of at least 80 DEG  C., to hasten the leaching and ensure complete regeneration of the cellulose.ALSO:A filter-tip for a cigarette comprises a foraminous rod of regenerated cellulose produced by forming a mixture of (a) a viscose having a bull-fall viscosity of at least 150 seconds and a salt-point of at least 15, (b) a water-soluble salt which forms an alkaline solution in water, of average particle diameter less than 600 microns, the ratio of salt to viscose being at least 3 : 1 by weight, (c) at least 80% by weight of the cellulose in the viscose of a water-insoluble particulate filler; extruding the mixture through a die into an alkaline bath saturated with the ions of the water-soluble salt and at a temperature more than 90 DEG C. to form a rod, removing the rod from the bath when regeneration of the cellulose is substantially complete, and bringing the rod into contact with water to dissolve the salt particles (see Division C3).  Exemplified filters contain as water-insoluble fillers a mixture of powdered cellulose and cellulose fibres or an activated powdered carbon adsorbent.  These may be used as the inner or adsorbent part of a two-part filter tip or may be used to replace the whole filter tip.  Before use, the cellulose rod is usually desulphurised and bleached, unless it contains a dark-coloured adsorbent.
Patent GB-999595-A (GB)
Title: Improvements in or relating to oximes and the manufacture thereof
IPC: A61K31/15
Filed: 1963-12-23
Abstract: The invention comprises compounds of the formula <FORM:0999595/C2/1> where R is hydrogen or an alkyl group of 1-8 carbon atoms or an alkenyl group of 1-8 carbon atoms, X is chlorine or bromine and n is 1 or 2. The compounds are made by reacting an aldehyde of the formula <FORM:0999595/C2/2> with a hydroxylamine H2N-OR, preferably in the presence of an inert solvent.  The hydroxylamine may be added as an acid addition salt, in which case an alkaline reagent e.g. sodium acetate, is added to the reaction mixture to liberate the free base. The novel compounds can be reduced with lithium aluminium hydride in the presence of an inert solvent at 0-150 DEG  C. to the amines of the formula <FORM:0999595/C2/3> which may be isolated as their acid addition salts.  The aldehydes of the formula II can be made by reacting a -tetralone or benzsuberone with dimethyl formamide and a phosphorous halide.  The hydroxylamines, H2N-OR, wherein R is alkyl or alkenyl, can be prepared treating a hydroxy urethane with an alkyl or alkenyl halide and hydrolysing the product with aqueous alkali metal hydroxide.  Specification 341,141 is referred to.

Title: Improvements in and relating to Continuously Moving Shears
Inventor: ELINEAU HUBERT JEAN
IPC: B23D25/10
Filed: 1966-11-11
Abstract: 1,156,927. Flying shears. SECIM. 11 Nov., 1966, No. 50762/66. Heading B3W. A double-crank flying shear includes a misscut mechanism and comprises two connecting rods each carrying a blade, the big-end of each connecting rod being rotatable on an eccentric which in turn rotates on the crank-pin of a motor-driven crank-shaft, the eccentric being driven by a first planetary member which rotates about the crank-pin axis and meshes with a first satellite wheel, the journal of which is carried by an arm of the crank-shaft, a second satellite wheel being mounted on the same journal and meshing with an internally toothed ring gear which is concentric with the crankshaft and there being guide means for the small end of the connecting rod. The crank mechanisms carrying the blades 2 and 3 are symmetrical about the feed path 1 of the material to be cut. The big-end 5 of the rod 6 rotates on an eccentric 8 which runs on the crank-pin 9 of a crank-shaft 10. Both ends of each connecting-rod are similarly supported. The miss-cut action is provided by the eccentrics 8, which vary the relative positions of the connecting rods and their crank-pins so that the cutters 3 and 4 do not reach the cutting position on every cycle of the shear. A planetary gear 17 is secured to the eccentric and meshes with a first satellite gear 18 secured to a shaft 19 which is rotatably mounted in an extension of the crankarm 20. Freely rotatable on the shaft 19 is a second satellite gear 22 which meshes with an internally toothed gear ring 21 which is coaxial with the crank-shaft and is secured to the shear frame. The gear 22 is connected by a slidable pin 24 to a plate 23 which is secured to the shaft 19. As the crank-shaft rotates the gear 22 rolls inside the ring 21 and drives the shaft 19, the gear-wheel 18 and the gear 17, so that the eccentric rotates on the crank-pin at a speed determined by the ratios of the gear train. To make the miss-cut mechanism inoperative the pin 24 is moved axially so that it is withdrawn from the gear-wheel 22 and enters a recess in the crank-arm, thus locking the shaft 19 and the gears 17 and 18 to the crank-shaft. The shear then cuts on each cycle. In a modification, Fig. 9 (not shown), the toothed gear ring 21 is rotatably mounted on the crank-shaft and is driven from the crank-shaft by gearing including a variable-ratio gear-box. The small end 7 of the connecting rod, instead of being mounted on an eccentric carries a roller (30), Fig. 7, which bears on a cam surface (31), designed so that the blade (3) is perpendicular to the material at the time of cutting. Alternatively, the small end is connected to its supporting crankpin by a block which pivots on the crankpin and slides in a slot elongated longitudinally of the connecting rod.
