Title: Improvements in or relating to free flowing thermoplastic granules and method of making the same
IPC: C08L35/06
Filed: 1954-12-21
Abstract: A composition comprises thermoplastic granules of an alkali-soluble copolymer of 10 mols. of a vinyl ester of a saturated organic acid containing from 1 to 6 carbon atoms with from 0.05 to 1.5 mols. of an unsaturated organic acid of from 3 to 6 carbon atoms, or a partial salt of said acid or its partial ester, or a partial ester of maleic acid, said granules being intermingled with from 0.1 to 5 per cent of a powdered alkali-soluble copolymer of styrene with maleic anhydride or a partial ester thereof derived from up to 1 mol. of alkyl alcohol containing from 1 to 10 carbon atoms.  The vinyl ester may be derived from formic, acetic, propionic, butyric, valeric or hexanoic acid and the other component of the granular copolymer may be acrylic, crotonic, methacrylic, itaconic or maleic acid, monoisopropyl maleate or the partial ammonium salt of monoisopropyl maleate.  The partial ester specified in the production of the powdered copolymer is the mixed partial ester of sec.-butyl alcohol and methyl alcohol.  The compositions may be prepared by thoroughly mixing the wet or dry granules with the dry powder and the mixtures are free flowing, anti-caking on drying at elevated temperatures and give clear solutions in aqueous alkali. The products have application in the adhesive, textile and paper fields.

Title: Improvements in or relating to logic systems
IPC: G02F3/00
Filed: 1956-12-04
Abstract: 821,661. Digital electric calculating-apparatus. WESTERN ELECTRIC CO. Inc. Dec. 4, 1956 [Dec. 7, 1955], No. 37026/56. Class 106 (1). [Also in Group XL (b)] An optical logic system including " AND ", OR " and " INHIBIT " circuits employs a plurality of electrically-actuated light gates in which electroded crystals control the passage of polarized light to detecting means. Any of the six birefringence and electro-optical phenomena of ferro-electric crystals may be utilized, some effects being relatively insensitive to temperature effects. In Fig. 1A, ferro-electric capacitors 4, 5 with transparent electrodes are separated by a polarizer 6 which is at 90 degrees to polarizer 3 and analyser 7. Crystals 4, 5 must each receive potential from terminals 10, 11 for light to be transmitted between source and photo-cell and the device constitutes an " AND " gate. In a modification (Fig. 1B, not shown), the attitudes of the crystals are changed and quarter-wave plates are interposed for temperature compensation. A bias may be applied to the second gate of the system to maintain it transmitting, a pulse turning off the stage. In a further modification the capacitors are side-by-side between polarizers 3, 7 with their domains such as to be normally opaque and they are rendered transmitting by a positive pulse to any of the capacitors, thus constituting an " OR " system (Figs. 2A, 2B, not shown). An " INHIBIT " system (Fig. 3A) comprises polarizer 3 and analyser 7 at 90 degrees to polarizer 6 and two ferro-electric capacitors 4, 5 with their C domains parallel to the incident light. A source of positive potential 25 connected to one terminal maintains crystal 4 normally transmitting, a pulse at the input of crystal 5 allowing light to pass to photo-cell 8, whilst a further pulse at crystal 4 renders the latter opaque and prevents the light reaching the photo-cell. A bistable flipflop or memory cell combines the " OR " and the " AND " systems (Fig. 4, not shown). A serial binary adder using four " AND," three " OR," a single " INHIBIT " and a single onedigit delay circuit is described (Fig. 5C). The capacitors defined by electrodes 110-115 form three two-input " AND " gates, representing a single " OR " gate at the photo-cell 116. Capacitors with electrodes 120, 121, 118, 122, 117 and 123 depict three " AND " gates and electrodes 126-129 define three " OR " gates. Capacitors 130, 131 form an inhibit circuit. The photo-cell 135 again acts as an " OR " gate. The capacitors may be used simultaneously in two independent logic systems (Fig. 6). The light from source 171 after polarization passes through the crystals 160, 161, 162 which are in parallel with light shields between them, thus constituting an " OR " system with an output at photo-cell 177. A second source 181 passes its polarized light through each crystal in series, if an appropriate pulse is applied to the electrodes, and forms an " AND " circuit with an output at photo-cell 190. Specification 717,104 is referred to.

Abstract: 1,013,095. Stud fasteners. F. T. PRODUCTS Ltd. Sept. 21, 1964 [Sept. 20, 1963], No. 37122/63. Heading E2B.  A fastener made of resilient synthetic plastics material for securing two members 18, 19 together comprises a shank 14, a handle 13 at one end of the shank, a transverse bore 15 at the other end of the shank, a locking pin 12 in the bore extending transversely from opposite sides of the shank and, located on the shank between the handle and the pin, a cup-shaped flange 17 having its concave face towards the pin. In one embodiment the shortest distance between the pin and the periphery of the flange is not greater than the overall thickness of the two members 18, 19 when the fastener is inserted through apertures in the two members. The panel member 18 has a circular aperture dimensioned to fit closely round the shank 14 and the panel member 19 has a generally circular aperture with a pair of diametrically opposed slots. The rim of the aperture in panel 19 has circumferential ribs 23, 23a. The fastener shank 14 is first inserted through the aperture in panel 18 and the pin 12 is positioned in the bore 15. The fastener is then rotated until the pin arms coincide with the slots in the aperture of panel 19 and is pressed therethrough and rotated through 90 degrees until the ends of the pin engage in indentations in the ribs 23, 23a. The resilient flange 17 provides a spring pressure on the two panels and in addition seals the apertures in the two panels. In a modification the panel 19b has a non-circular aperture into which fits a resilient bush 25 which receives the fastener. The bush has a neck 27 in the form of an external groove into which fits the panel 19B, an annular head 29 seating on the surface of the panel 19B. The bore of the bush has two longitudinal grooves which allow the pin 12B to pass therethrough and which give extra resilience when the bush is positioned in the panel 19B. The fastener is used in the same way as that first described.

Filed: 1928-12-17
Abstract: 326,795. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Dec. 17, 1928. Denaturing alcohol.-Mixtures suitable for denaturing alcohol which may contain nitrogen compounds such as pyridine homologues and nitriles, and sulphur compounds such as thiophene are made by passing mixtures of unsaturated hydrocarbons such as acetylene and ethylene with ammonia and if desired with inert gases or vapours over catalysts consisting of or containing substantial amounts of solid inorganic sulphidic compounds such as pyrites or spent gas-purifying material at 250-600‹ C. The catalysts give up sulphur and also catalyze the reaction. When steam is employed as diluent, the condensate separates into two layers, and the aqueous layer alone or a fraction of the condensate such as that which distils over up to 200‹ C. may be used to denature alcohol.
