Title: Method of treating the surface of a glass article
IPC: C03C8/00
Filed: 1974-05-13
Abstract: 1465372 Coating glass articles ANCHOR HOCKING CORP 13 May 1974 [14 May 1973] 21159/74 Heading C1M A surface portion of a glass article (e.g. a bottle) is coated by:- (a) preparing an enamel composition in dry powder from which comprises a vitreous enamel frit (whose softening point is below that of the glass) and a refractory inorganic component (e.g. TiO 2  pigment); (b) preheating the glass article to a temperature at which it is electrically conductive, but which is insufficient for the frit to fuse to the glass; (c) applying the enamel composition to the article by an electrostatic dry powder spray process so that the powder adheres to the glass by electrostatic attraction and not by thermal fusion; and (d) firing the coated article at a temperature sufficient to fuse the particles of the enamel composition to the glass surface as discrete droplets, but insufficient to allow the particles to coalesce to form a smooth film. The method may be used to simulate a sandblasted appearance (using a peak firing temperature of 1000‹-1100‹ F.) or an acid-etched appearance (peak firing temp. at 1125‹-1200‹ F.). Preferably the peak firing temperature is 50‹-300‹ F. above the softening point of the frit. The glass article may be preheated to 150‹-450‹ F. The enamel composition may be applied in a pattern to the glass article, and may be applied in an amount of 0À0002-0À0006 oz./in<SP>2</SP>. The enamel composition preferably comprises 80-99À5% by weight frit and 0À5-20% pigment, and preferably the composition is kept substantially at room temperature until it contacts the glass. A suitable lead borosilicate vitreous enamel frit comprises, in weight per cent: SiO 2  25-30, B 2 O 3  5-10, Na 2 O 3-7, PbO 45-55, ZrSiO 4  5-10, TiO 2  2-5 and Al 2 O 3  2-5.

Title: Improvements in or relating to gasometer vessels for methane fermentation of manuresand other like materials
IPC: C12M1/107
Filed: 1947-08-05
Abstract: Apparatus for the methane fermentation of manure and similar substances as in the parent Specification is characterised by the fermentation vat and, if desired, the dome being subdivided by partitions into a plurality of compartments, means being provided to permit individual charging of any compartment without interrupting gas delivery in the others.  Recharging may be effected through an opening in the dome above each compartment, closure being made by means of a plug with a plastic joint or by a domed plate removably attached to the dome and dipping into a water trough around the opening.  When simultaneous aerobic and anaerobic fermentation is to be effected in different compartments, for example with heat exchange as described in Specification 621,747, the partitions of the dome may dip into troughs at the top of the partitions of the vats, said troughs being serviced from the hydraulic seal of the outer wall of the dome.  Each compartment may have a gas outlet connecting to a common passage and an isolating valve.  When an aerobic fermentation takes place in all compartments, partition of the dome is not essential although partitions may be provided, at least in the upper part, for accumulation of gas.

Title: Method and apparatus for automatically charging the coking chambers of coke oven batteries
IPC: C10B31/00
Filed: 1964-05-22
Abstract: 1,013,316. Charging coke oven batteries; drying coal. ALLIED CHEMICAL CORPORATION. May 22, 1964 [May 22, 1963], No. 21308/64. Headings F4B and F4G. Pulverulent coal is charged to the ovens of a coke battery through a transport main and valved branches feeding the individual ovens in a carrier gas, propulsion jets being spaced along the main to deliver carrier gas to the stream of coal and gas. Wet pulverulent coal from a hopper 24 is fed through a drier 21 past a gate 66 to a hot bin B to form a flowable mixture with steam or other carrier gas from an inlet 67. A gate 69 controls the flow of coal to a lower hot bin C where further steam from an inlet 71 is added to produce a fluent mixture. Under control of a gate 73 the coal passes through a crusher 74 and a transport container D to a main M. Steam is delivered to the main M by spaced jets arranged to deliver a fan of steam and carrier gas into the main M (Figs. 4 and 5, not shown), to propel the coal to one of the branches 122 leading to a coke oven. A programmer-controller E controls the drive for scrapers in the drier 21 to regulate the flow of coal. When a desired charge has been fed into bin B, the drier gate 66 is closed and the bin 69 opened to feed the charge to bin C. When bin C is filled to a predetermined level, gate 69 is closed and gate 73 leading to the metering crusher 74 opened. The steam valves controlling inlets 67 and 71 to bins B and C are also operated by the controller E. When gate 73 leading to the transport chamber D is opened, the crusher 74 is actuated and steam delivered to the transport jets. The rate of operation of crusher 74 is reduced if pressure in the chamber D rises above a predetermined level. The capacity of bin C is chosen to equal the desired charge of an oven, so that on bin C being emptied, the valve 123 controlling the branch of an oven which has just been charged is closed, and the cycle recommenced to charge a second oven. In a modification, the controller E operates to maintain a charge of coal in bin C and a continuous flow of coal is delivered to the main M. The valves 123 controlling the branches to the ovens are operated in a timed sequence to charge the ovens in turn. The drier, Fig. 7, comprises an open-topped casing with a series of staggered horizontal grate bars 29 above an outlet, and reciprocating scraper bars 28 operated by a rack-and-pinion 51, 52. Specification 814,791 is referred to.

Title: Improvements in or relating to catalytic polymerisation processes
IPC: B01J19/18
Filed: 1944-11-01
Abstract: <PICT:0585434/IV/1> <PICT:0585434/IV/2> In a catalytic polymerization in which normally there is contact between the reaction material and the catalyst for an extended period before polymerization is initiated, the reaction vessel is charged with reaction material which has previously been in an on-stream stable operation, fresh feed of reaction material and catalyst is added in proper quantities for on-stream operation and the product is continuously withdrawn. In the Figure, a vessel 1 has an external jacket 2 and an internal hollow annulus 3 connected together by pipes 4.  The jacket has an inlet 5 and an outlet 6.  The vessel also contains an agitator 7, a reaction material feed nozzle 8 and a catalyst feed nozzle 9, and overflow lines 10.  A refrigerated overflow line 11 with valve 12 discharges into a second vessel 13 identical with reaction vessel 1. The reaction vessel 1 is filled with a mixture of isobutylene, isoprene and methyl chloride and cooled to -138 DEG  F.  A cooled catalyst solution is injected at an increasing rate until polymerization commences, when the feed is cut back.  When it is desired to take vessel 1 out of commission, vessel 13 is filled with reaction material and cooled to reaction temperature; valve 12 is opened and the overflow from reaction vessel 1 allowed to enter vessel 13 until this vessel is filled with a charge of the same composition as that of reaction vessel 1.  Then feed nozzles 8 and 9 are closed and 15 and 16 opened.

Abstract: 823,403. Direct connections between conductors. PYE Ltd. July 10, 1957 [July 10, 1956], No. 21360/56. Class 38 (1). A joint between the inner conductors 4 of coaxial transmission lines is made by brazing a brass collar 5 in the end of each conductor, inserting a member 1 preferably of metal so that its ends are received in collars 5 and securing it by screws 3 passing through holes in collars 5 and engaging peripheral V-shaped grooves 2 in member 1, the tightening of the screws drawing the ends of conductors 4 into firm engagement. A locating ring 6 is provided round member 1. The outer conductors 7 are connected by bolted flanges 8. In an alternative construction only one end of the member has a V-shaped groove while the other fits closely in the end of one conductor and is brazed therein, while the grooved end is inserted into the other conductor and engaged by set screws. The ungrooved end is of larger diameter than the grooved end and a shoulder is thus formed in the member. The member may be polygonal instead of cylindrical, or may be ribbed or fluted over its outer surface. The grooves may not be V-shaped although they must have an inclined wall, and they need not be continuous.

Title: Improvements in drying and carbonization of lignite and the like for the production of a tar rich in undecomposed bitumen
IPC: C10B7/06
Filed: 1920-07-15
Abstract: 169,847. Seidenschnur, F. July 15, 1920. Coking processes; producers.-Coal, lignite, &c. is dried in a chamber V, carbonized in a chamber Sch, and the product partly gasified in a producer G and partly collected. A pump H1 draws off the steam and gases from the drying-chamber and delivers them partly to a chamber M, in which they mix with the products of combustion of the producer gas and air, partly to below the grate of the producer and partly to a mixing- chamber m. A pump H2 supplies air to the producer and to the mixing-chamber M, the hot gases from which pass to the carbonizing-chamber Sch and through the mixing-chamber m to the drying-chamber V. Thus the lignite is dried by hot waste gases charged with a certain amount of steam, and the carbonizing is effected by a mixture of hot gases and steam at a temperature not over 500‹ C. The material in the drying and carbonizing chambers may be treated on stepped grates or on movable chain grates.
