Title: Pyridoxine and derivatives thereof
IPC: C07D498/18
Filed: 1966-10-19
Abstract: The invention comprises cyclic pyridoxine esters of formula <FORM:1100694/C2/1> where X is a radical derived from a polybasic inorganic acid or a hydrocarbon-substituted derivative thereof.  The compounds are prepared by reacting an oxazole of formula <FORM:1100694/C2/2> where R is a cyano or a hydrocarbonoxy radical with a cyclic ester of 2-butene-1,4-diol of formula <FORM:1100694/C2/3> where X is as above.  The compounds may be hydrolysed to pyridoxine.  In examples, pyridoxol cyclic 3,4-carbonate is obtained by reacting 2-butene-1,4-diol cyclic carbonate with 4-methyl-5-ethoxyoxazole and with 4-methyl-5-cyanooxazole, and 4-methyl-5-ethoxyoxazole is reacted with 2-butene-1,4-diol cyclic sulphite to obtain pyridoxal cyclic 3,4-sulphite, with 2-butene, 1,4-diol cyclic sulphate to obtain pyridoxol cyclic 3,4-sulphate, with 2-butene 1,4-diol cyclic phosphate to obtain pyridoxol cyclic 3,4-phosphate, with 2-butene-1,4-diol cyclic butyl borate to obtain pyridoxol cyclic 3,4-butyl borate, with 2-butene-1,4-diol cyclic phenylboronate to obtain pyridoxol cyclic 3,4-phenyl boronate, with 2-butene-1,4-diol cyclic diethyl silicate to obtain pyridoxol cyclic diethyl 3,4-silicate, and with 2-butene-1,4-diol cyclic aluminium isopropoxide to obtain pyridoxol cyclic aluminium isopropoxide; all the products are hydrolysed with hydrochloric acid to obtain pyridoxine hydrochloride.  Other starting materials are mentioned.

Abstract: 1403786 Semi-conductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 11 Oct 1972 [14 Oct 1971] 46903/72 Heading H1K Contact points 4 on a semi-conductor chip 3, e.g. an I.C. are bonded to the inner ends of conductor tracks 2 located on an insulating foil 1, e.g. of polyimide, the outer ends of the tracks being attached to holding elements on the ends of the flat strip conductors 5 the outer ends of which project from opposite sides of an encapsulation or housing for the chip. The width of the foil exceeds the spacing between opposed pairs of holding elements, causing the foil to bow enabling the uncontacted face of the chip to bear against and if desired, be soldered to a cooling plate embedded in the encapsulation or incorporated in the housing wall. In the embodyment shown in Fig. 2, the holding element consist of claws 7 ,8 formed from the ends of the flat teeth of comb-like conductor structures cut from standard strips of indefinite length. The conductors are held between the engaging rims of thermoplastic housing parts 13, 16 which are welded together, the chip being pressed against a cooling plate 14 moulded or held by a snapfastener in the wall of part 13 by an internal projection 15 from the resilient wall of part 16. The housing may be filled with synthetic resin and the conductive teeth finally severed from the combs and bent up if required for mounting to a printed circuit board. In an alternative embodiment synthetic resin is moulded around the assembly to chip, foil, conductors and cooling plate to form a solid block from which the conductors protrude.

Abstract: 1,115,264. Thermocouples. ULTRA ELECTRONICS Ltd. 8 Feb., 1967 [8 Nov., 1965], No. 47202/65. Heading H1K. A thermocouple for use in a sonic pyrometer consists of a tube 14 (Fig. 2), through which gas can flow, forming one limb of the couple and another element, in this case tube 15, forming the other limb joined to it at its open end. In an alternative construction the mouth of the tube is cut at an angle to its axis and the other element is a wire within the tube electron beam welded into a slot in the mouth of the tube. In both cases the thermocouple elements are of noble metals, and the assembly is mounted with the junction disposed within a convergent nozzle through which the gas whose temperature is to be measured is drawn at sonic speed. The tube or tubes have ports spaced from their mouths through which the gas flows out.

When the starting handle is moved to stop the loom, it pulls down a rod 31 to disengage a catch 37 from a lug 38, thereby allowing a follower 27 to engage a cam 29 on the crankshaft; the concave part of the cam permits a spring 28 to press a brake shoe 26 against a shoe 22 to lock a moveable back rest 11. When the loom is restarted, the catch 37 re-engages when a high lobe of the cam encounters the follower 27 just before picking. Conversely, the rod may be lifted when the loom is being stopped, in which case the follower 27 normally runs on the cam 29 and the back rest is locked for part of every cycle, but is kept unlocked when the loom is stopped. In another embodiment, the connection from the starting handle controls displacement of an easing motion roller situated between the warp beam and the moveable back rest.

Abstract: 1,081,436. Selective printers. BUCHUNGSMASCHINENWERK KARL MARX STADT VEB. Dec. 9, 1964, No. 50066/64. Heading B6F. An output printer for calculating accounting or data-processing machines comprises a line of type members 3 mounted on supports 2 each individually and pivotally mounted on a shaft 1 with a clearance S so that when the support 2 is swung to effect impression by a pressure arm 11, and which is suddenly arrested by an adjustable stop 18, 19, 20, the type members 3 travel by momentum to effect even impression. Selective rotation of the type members 3 is controlled by setting stops 9 which are engaged by an extension of the support 2 urged by a spring 6 in clockwise direction. At this time a cam 15 starts the swinging action of all the typemembers and as the extension leaves the setting stops 9, a lever 21 with a holding comb 25 aligns and locks the type-members in set position. When the cam 15 rotates to a position enabling a follower 14 to drop into a recess 17, the pressure member 11 swings the shaft 1 to effect impression. In an alternative construction described (Fig. 5, not shown) the type-members are selectively rotated by a link (33) a bell crank (29) and a slider (28). A slotted connection between the link and bell crank permits the impression action.

The pad may be of polyurethane, may be ¢ inch thick, and may have the following physical properties: Shore A-2 durometer 40 to 100; ball hardness 1.5 to 80 1bs; compression modulus (1%) 100 to 3000 psi; compression 50% 150 to 5000 psi; recovery from 50% compression at least about 75%; and standard compression set not more than about 15%. The pad may have bonded to its smooth surface an adhesive component having an inner pressure-sensitive adhesive layer, a central thin strong flexible film e.g. of plasticized polyvinyl chloride; and an outer pressuresensitive adhesive layer, the bond between the inner adhesive layer and the smooth surface of the pad being at least twice the bond obtainable by merely pressing the outer adhesive layer against a similar smooth surface. The adhesive member may be produced by holding together and bonding the flat smooth surface and the inner face of the adhesive component whilst the outer face of the adhesive layer is isolated from the pad. The pad may he formed from a liquid self-curing resinous composition e.g. a polyurethane-forming composition, while maintaining in contact with the composition the inner adhesive layer of a pressure sensitive adhesive sheet material having an inner pressure sensitive adhesive layer a central thin strong flexible barrier film e.g. a vinyl resin film, and an outer pressuresensitive adhesive layer. A steel shipping drum may have the member adhered to the bottom thereof, the thickness of the pad being just sufficient to maintain the exposed face of the pad within the plane of the outer edge of the surrounding chime of the drum.
