Filed: 1973-07-20
Abstract: 1424283 Conveying containers DART INDUSTRIES Inc 20 July 1973 [24 July 1972] 34835/73 Heading B8A Bottles B are gripped in respective chucks 16 which comprise laterally movable members 18, 20, carried by each link 14 of an endless conveyer 10. The lower run of the conveyer carries the bottles through a spray booth (not shown, but including the space adjacent and below the lower run of the conveyer in Fig. 1). The bottles are subject to electrostatic spraying of a polymeric coating (thermoplastic polymers such as polyethylene polymers and copolymers). It is a feature of the invention that each chuck forms a cavity shaped to receive an extended portion of each bottle and fluid is introduced to purge the cavity as the chucks pass along the lower run of the conveyer. Each member 18, 20 is slidable relative to its associated conveyer link 14 by virtue of pins projecting from the members which extend through slots 42 of the conveyer links. Heads 46 carried by the pins function as cam followers when they are engaged by cam rails 30,30. In this way the chuck is opened and closed at each end of the lower conveyer run (to first engage a bottle, and then discharge it). An electrically conductive path is provided from the chuck to conductors 38 carried by side frame support members 36, 36. The fluid purging medium is air, and it is passed through conduit 60 and passages 64, 62.

Title: Preparation of a product adapted for the treatment of fibrecontaining organic materials
IPC: D06M15/03
Filed: 1947-12-31
Abstract: A substance capable of use in the treatment of fibrous organic materials, e.g. as an assistant in textile-dyeing and like operations, is prepared by concentrating whey or whey-like dispersions obtained as by-products in the manufacture of cheese or milk-sugar.  The concentration may be carried on sufficiently to produce a salve-like product or a powder and may be effected in two stages.  The albumen which separates may be removed or it can be broken down into simpler compounds by acidification of the whey with lactic acid or by bacterial action.  The milk-sugar present can be partially split into galactose and glucose.  A disinfectant, preferably one having a bleaching-action, such as a sulphite, and a preservative such as phenol, cresol, naphthol, chlorinated cresol, diphenyl oxide or etheric oil can be added. The sugar and albumen content can be increased by the addition, either before or after concentration, of glucose, galactose, or milk-sugar, or albumen or its decomposition products such as pure or chemically-modified amino acids.  Oils and fats in emulsion or solution, sulphite waste liquor, or wetting-agents such as triethanolamine or other textile assistants can also be included. The pH of the concentrate can be adjusted by the addition of acids or alkalies.  The products protect the fibres from alkaline attack and can be used in printing and discharge pastes and in dye-baths, e.g. in conjunction with vat, azo, acid, basic and mordant dyes and in azoic and aniline black processes.  They may also be used in bleaching.ALSO:A substance capable of use in the treatment of fibrous organic materials, e.g. as an assistant in tanning, leather-dressing, textile-dyeing and like operations, is prepared by concentrating whey or whey-like dispersions obtained as by-products in the manufacture of cheese or milk-sugar.

Title: Improvements in and relating to electric condensers
IPC: H01G4/12
Filed: 1947-12-31
Abstract: 648,866. Condensers; electrophoretic coating. DENES, P. Dec. 31, 1947, No. 35379. Convention date, May 11, 1943. [Classes 37 and 41] [Also in Group VIII] A condenser is made by coating a metal with a layer of finely-distributed ceramic material of very low vitrification and with a sintering temperature lower than the melting point of the metal foil and by sintering together the foil and ceramic layer. The sintering is effected in vacuo, in a neutral or reducing atmosphere at atmospheric or higher temperature or in an atmosphere containing 4 per cent of oxygen, or at atmosphoric or increased pressure. The foil is a metal or alloy of low permeability, e.g. iron, nickel, cobalt or chromium and the ceramic which may consist wholly or mainly of rutile or of zirconium dioxide, magnesium titanate or steatite, is applied by spraying or electrophoresis. Three metal ribbons may be passed each under a roller in the same or separate basins containing a ceramic suspension. Each ribbon passes between two parallel plates in the suspension, the plates being connected to a current source to form anodes, the ribbons also being connected to the current source. The coated ribbons are wound together preferably non-inductively with two narrower metal ribbons interposed. The ends of the coil are coated with ceramic and the coil is then sintered. In Fig. 2 the ribbons pass from a lower chamber 18 under increased air pressure between felt strips 16, 17 into a chamber 3 containing the ceramic suspension. Metal plates 5 forming anodes and the ribbons are connected to a current source 4. The coated ribbons are pressed together by rotated rollers 23. The ribbons may be perforated by co-acting pins 30, 31 in openings in plates 26, 27, and alternate ribbons are perforated by pins 36, 37 in openings in plates 28, 29 at a different level. The plates are moved in the directions shown by the arrows to pierce the ribbons when the movement of the ribbon is stopped, so that the ribbons after passage between the rollers 23 are torn by the subsequent winders. The ceramic layer is thickened about the perforations by increasing the cataphoresis current at these places. The coils may be placed in the basin 3 and are electrostatically screened. The Specification as open to inspection under Sect. 91 comprises also sintering a single coated ribbon or metal plate and then coating the ceramic layer with metal by spraying or cathodic dispersion, said metal coating being of smaller area than the metal foil or plate and being then covered with insulation. To avoid arcing at the edges of the plate the insulation is made thicker there. This subject-matter does not appear in the Specification as accepted.
