Title: Syrup dispensing nozzle assembly
IPC: A23G3/02
Filed: 1975-01-28
Abstract: 1481894 Syrup dispensing device BIG DRUM Inc 28 Jan 1975 [15 Feb 1974] 3733/75 Heading A4T [Also in Divisions A2 and B2]  The unit 20 comprises a manifold 26 having a plurality of nozzle heads 30, a conduit 29 through which syrup is passed from a tank under pressure and in which is interposed a valve 35 which may be actuated to supply pressure to the manifold in timed relationship to the intermittent movement of the conveyer 25. Extending longitudinally through manifold 26 are bores which form a common syrup supply passage 40 and ball controlled outlet 41 lead upwardly from passage 40 one outlet being provided for each nozzle head 30. Outlet 41 leads upwardly into a tubular ball chamber 42 and at the junction with the chamber there is a ball seat 43. A ball 45 is mounted for free vertical movement in the ball chamber 42. When cones C are positioned under nozzle heads 30 syrup is supplied under pressure to the manifold 26 by actuation of the valve 35 and fills the passage 40. All of the identical balls 45 are lifted simultaneously from their seats 43 when sufficient pressure is created throughout the length of passage 40 and syrup flows to all of the nozzle heads 30. When valve 35 closes the interruption of flow pressure permits all of the balls 45 to drop on to their respective seats 43. A suck back effect is created when this occurs and a non-drip effect is caused at the nozzle tips 50. The tips 50 are spaced from each other in such a manner that syrup issues as separate streams.

Title: Improvements in induction heating systems
IPC: H05B6/06
Filed: 1959-02-03
Abstract: 875,210. Valve oscillator circuits; R.F. couplings. SOC. DE TRAITEMENTS ELECTROLYTIQUES ET ELECTROTHERMIQUES. Feb. 3, 1959 [Feb. 7, 1958], No. 3789/59. Classes 40(6) and 40(7) [Also in Groups XI and XXXVI] A high-frequency induction heating system which is to be used as an auxiliary heating source for a glass fibre spinner operating at temperature of the order of 1,000‹C. has the heating coil and immediate circuit separate from the valve oscillator supplying the power, which it is necessary to place in a region of lower temperature. The oscillator and heater units are coupled by means of a co-axial cable as indicated in the figure. The oscillator is based on triode valve 2 whose anode is connected to the central conductor 24 of the coaxial line and also to inductance 11 in series with the coupling transformer 12 coupling the anode and grid circuits. A capacitor 10 across inductance 11 is adjusted so that the impedance of the feed-back circuit increases with increase of operating frequency and serves to stabilize the voltage output of the oscillator. The heating coil 18 is tuned by capacitor 19 and operates as a step-up auto-transformer, the input from the co-axial line being connected across tappings 23 and 31. It is preferred to arrange a two-part connector at 20, 21, 22 so that the actual heating coil may be replaced if necessary. Because the impedance of the working circuit is much lower than that of coil 11 the operating frequency of the system is determined by the values of components 18 and 19.

Title: Bonding metal to ceramic
IPC: C04B37/02
Filed: 1975-01-29
Abstract: 1494951 Ceramic-metal seals GENERAL ELECTRIC CO 29 Jan 1975 [4 March 1974] 3848/75 Heading B3V A metal member is bonded to a ceramic substrate by providing a layer of the metal in reacted form on the metal member, curving the member, assembling the member and substrate with the layer against the substrate and heating the assembly to a temperature above the eutectic temperature of a mixture of the metal and reacted metal but below the m.p. of the metal to form the eutectic which wets the ceramic to form the bond upon cooling. As described the reacted metal is the metal oxide 22, Fig. 2b and is deposited on the surface of a piece of copper 21 or is provided thereon by anodization, chemical reaction or by heating in a reactive atmosphere of 0À01-0À50% by volume of oxygen, balance nitrogen, preferably 0À4% oxygen at 1050 C. Portions of the layer, where the metal is not to be bonded to the alumina substrate, are now removed before the member is bent against a mandrel. Heating to 1065-1083 C. in a less reactive atmosphere of 0À3% oxygen follows to ensure that the oxidized copper is not reduced as the eutectic is formed and the metal unbends, Fig. 2e, to form the joint. The metal 21 may be shaped after sealing to the substrate for semiconductor applications. As in Specification 1,394,322 Fe, Ni, Co, Cr and Ag may be used and alloys such as Cu-Ni, Ni-Co, Cu-Cr, Cu-Co, Fe-Ni, Ag-Au, Be-Cu and ternary compositions of Fe, Ni and Cu. Alternative reactive atmospheres are a mixture of an inert gas, e.g. argon, helium or nitrogen with a minor amount of oxygen, phosphine or hydrogen sulfide. Alternative substrates are beryllia, fused silica, titanates and spinels.

Patent GB-927882-A (GB)
Title: Process for the production of halogenated olefin polymers and copolymers
IPC: C08L23/28
Filed: 1961-02-01
Abstract: Chlorinated polyolefins are produced by passing chlorine, optionally diluted with an inert gas, through a bed of the finely divided polymer in the presence of 0,5-5% by weight of an antistatic agent at a temperature above the temperature at the onset of the endothermal fusion phenomenon characteristic for the treated polymer.  The polymer may be a homopolymer of ethylene, propylene, butune, isobutene, pentene, hexene or a copolymer of such monomers.  The antistatic agent may be a quaternary amine salt such as triethanolamine-lauryl sulphate, stearamidopropyl-dimethyl-b  hydroxy ethyl-ammonium dihydrogen phosphate, dodecyl-trimethyl-ammonium chloride, octadecyl-trimethyl-ammonium chloride or dimethyl-benzyl-lauryl-ammonium chloride.  The temperature at the onset of the endothermal fusion phenomenon corresponds to the temperature of fusion of the crystallites in the polymer.  The polyolefin may be produced by a low pressure process using chromium oxide or a mixture of titanium tetrachloride, aluminium trichloride and tin tetrabutyl as catalyst.  The process may take place in a single stage, or in two stages, the first of which is carried out a lower temperature and preferably in the absence of the antistatic agent, the second stage at the higher temperature and in the presence of the antistatic agent.  Lighting the reaction medium is often an advantage.  The materials produced may be incorporated in polymers from vinyl chloride and styrene in an amount of from 5 to 50% of the total matter to improve the shock resistance.  Specifications 481,515, 799,952, 815,088 and 815,096 are referred to.
