Title: Forming glass articles
IPC: C03B11/10
Filed: 1964-04-10
Abstract: <PICT:1068312/C1/1> In a method of moulding a glass article (e.g. the faceplate of a cathode-ray tube) having a base portion and a peripheral flange portion connected to the base by a curved portion of small radius with the aid of an appropriately-shaped mould 10 and plunger 15, the formation of a "suck-up" defect is obviated by maintaining the temperature of the plunger surface in the area of the base, near the glass crizzle temperature, and by maintaining the temperature of the plunger surface in the area of the flange and area of small radius near the glass sticking temperature.  Such temperature control is effected by directing a liquid coolant against the base portion of the plunger but not against the flange and small radius portions.  The plunger 15 has a base having a convex surface 17, a flange surface 18 and a small radius portion 19.  A liquid coolant is supplied by a distributer 20 through nozzles 21 and directed against the bevelled edge of a baffle 25 interposed between the distributer 20 and the inner surface of the flange portion of the plunger. The liquid coolant thus flows down along the base portion to be discharged at 22, 23.  An insulating gasket 29 is placed between the baffle and the plunger flange portion.

Title: Apparatus for carrying out chemical reactions, particularly fluidised bed chemical reactions, and/or various physical and physico chemical operations
IPC: B01J8/10
Filed: 1964-04-13
Abstract: 1,059,077. Chemical contact apparatus. Z. KABATEK and M. PETRACEK. April 13, 1964 [April 13, 1963], No. 15096/64. Heading B1F. [Also in Division F4] Chemical reactions and/or operations such as drying, cooling or catalyst regeneration, which may or may not involve fluidised beds, are performed in the compartments into which space 1 is divided by radial walls carried on a rotating shaft 5, fluid being fed to these compartments from similar compartments in distribution chamber 8 each of which has a controllable inlet. Granular material for treatment enters successive compartments through inlet 6 and is discharged at outlet 7, the reaction having been completed in one turn of shaft 5. The compartments of chamber 8 communicate with those of space 1 through a grid 3, and may be stationary, or may turn with shaft 5, or may turn part of a revolution and then return under spring loading to an initial position. As each compartment of space 1 moves from loading position (I) to discharge position (V) (Fig. 3, not shown) it is successively fed with fluids whose nature, temperatures and pressure are independently controlled. Cover 11 at the top of space 1 has a series of variable apertures or filters of various resistance opening on each position. The radial walls in space 1 are steel frames filled by refractory material. Parts of grid 3 may be closed or the inlets to chamber 8 interrupted to apply pneumatic shocks to the material in space 1. Pulsing gas is emitted from hollow shaft 17 of a whirling device (Fig. 5, not shown). In operation a chemical reaction is facilitated by passing fluid media into space 1 at certain positions, while different media passed at other positions regenerate a catalyst. In drying, gases fed to successive positions may progressively decrease in temperature and vary in pressure as moisture content of the solid material in space 1 falls.

Abstract: 1349782 Hair pieces M D'ATABEKIAN 17 May 1971 [21 May 1970] 15221/71 Heading A4V [Also in Division B6] A continuous fringe for making hair pieces is made by repeatedly performing a cycle which comprises the steps of holding the support or backing filament in an extended condition, forming at least one loose hitch knot with the fed filament, passing the support filament through the hitch knot, tightening the fed filament around the support filament and cutting the fed filament to form strands. As shown in Fig.3-5 a fed filament 22 is passed over the fingers 24 and 26 connected at one end to the other by a pivot 28, the filament forming a U-shape the base of the U extending between the fingers. The two fingers lie in a common plane and can pivot with respect to each other in this common plane about the pivot 28. The fork is then pivoted about an axis parallel to the base of the U so as to form loops 30 and 32 of fed filament extending around fingers 24 and 26 of the fork. The two fingers 24, 26 are then moved towards one another by pivoting around pivot 28 so that the loops 30, 32 form two loose hitch knots in parallel planes. A spool on which is wound the support filament is then passed through the two knots to introduce the support filament, fingers 24, 26 are separated and returned to their initial position, the two strands of fed filament are pulled to tighten the knots around the support filament, whereafter the fed filament is cut to give strands of the required length. The support filament can be a twisted sewing thread. The fed filament may comprise a plurality of strands. The resulting fringes may be used for wig making.

Filed: 1957-05-14
Abstract: The invention comprises 1-b -isothiocyanoethyl-2-imidazolidinethione, and its preparation by reacting a soluble salt of b -[1-(2-thionoimidazolidyl)]ethyldithiocarbamic acid (e.g. the Na or K salt) with an ester of chloroformic acid at a temperature below about 35 DEG C., and decomposing the resulting alkoxycarbonyl-b -[1-(2-thionoimidazolidyl)]ethyl dithiocarbamate either by heating or on standing in the presence of a liquid.  The decomposition may be effected by heating in the presence of water or an inert organic solvent to 50-125 DEG C. until the evolution of gas ceases, or by standing at 20-50 DEG C. in the presence of water, an organic solvent, or a mixture thereof, until the evolution of gas ceases. Specified chloroformic esters are those of C1-4 alkanols, hydroxyethanol, methoxyethanol, and chloroethanol.  The compound of the invention reacts with aniline and dimethylamine to yield the corresponding thioureas.  The preparation of the corresponding imidazolidinone by a method similar to the above is also described.ALSO:Fungicidal compositions comprise 1-b -isothiocyanoethyl-2-imidazolidinethione with an inert carrier.  The compound may be dissolved in acetone and the solution diluted with water to give a suspension, or it may be used as an emulsifiable concentrate, e.g. 5 parts of compound, 90 parts of an aromatic naphtha or xylene, and 5 parts of an emulsifying composition, such as 2 parts of the water-soluble condensate of ethylene oxide and methylene bis-(diamylphenol), and 3 parts of calcium dodecyl-benzene sulphonate.  A wettable powder may be prepared by mixing 25 parts of compound, 70 parts of fire clay or mixtures of other finely-divided inert solids, 2 parts of a lignin sulphonate and 3 parts of a just dry preparation of octylphenoxypolyethoxyethanol.  This powder is suspended in water and sprayed, or may be diluted with finely divided inert solids to give dusts containing 1-10% of active agent. Alternatively, dusts may be prepared from the compound and inert solids.  Other agents may be incorporated in those compositions, e.g. other fungicides, a miticide, or an insecticide.  Control has been achieved against bean rust and late blight on tomato.  The corresponding oxygen analogue, 1-b -thiocyanoethyl-2-imidazolidinone, shows fungitoxicity.
