Abstract: 532,034. Switch contacts; oil-break switches. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 12, 1939, No. 23309. Convention date, Aug. 13, 1938. [Class 38 (v)] In order to prevent rebound and consequent arcing when closing the contacts of oil or other heavy-current switches, without however impairing the closing-shock absorbing capabilities of the contact-springs, two or more parallel - connected (arcing) contacts, as 7, 8, are provided with control springs 10, 11 having different natural periods of vibration so that when one tends to rebound, the other is in engagement with its moving contact 13 or 14. Instead of making one spring heavier, 11, as shown, similar springs may be employed, in which case they are secured to their contacts 7, 8 and the latter have different masses. The resilient contacts may both be mounted on the movable bridge-member 16, or one on 16 and one on the fixed structure. The main contacts are shown at 5, 6 behind the arcing-contacts.

Title: Improvements in and relating to photo-mechanical intaglio printing
IPC: B41B17/22
Filed: 1951-10-08
Abstract: 707,662. Photographic type-composing. HIGONNET, R. A. E., and MOYROUD, L. M. Oct. 8, 1951 [Nov. 2, 1950], No. 23392/51. Classes 98(1) and 98(2) A matrix member for a photographic type-composing machine carries character matrices each bearing an individual character having light-permeable areas so that exposure of a photosensitive surface through the matrix results in a characterimage with exposure areas corresponding to the light-permeable areas of the matrix. The matrix member may be made by engraving a lattice on a transparent disc, coating the disc with a photosensitive layer, and photographically printing transparent character images on, the layer. The characters be transparent on an opaque background, with a grid of opaque lines superimposed thereon to break up the character into a number of transparent areas. Preferably, as shown, the character is broken up by opaque lines 11 into transparent areas 10 in a manner adapted to each character. When the photosensitive surface (e.g. carbon paper) is exposed the areas thereof corresponding to areas 10 are light-struck. The carbon paper is then transfered to the printing surface, which is etched in the areas coresponding to the areas 10, forming cavities which receive the ink. Since the ink spreads in making the impression, the edges of areas 10 are made concave with respect to the bounding line 11 of the character. Specification 687,722 is referred to.

Title: Improvements in the production of films having a matt, porous, and non-adherent surface
IPC: D06N3/06
Filed: 1951-10-18
Abstract: Coatings and foils having a matt, porous, and non-adherent surface are produced from pastes which do not gel until heated of polyvinyl chloride and plasticizers, by adding thereto fillers containing in physically combined form a liquid, preferably water, which is insoluble in the plasticizer, and which is volatile at ordinary gelling temperature, applying the resulting mass to a substrate and heating to gelling temperature.  Plasticizers specified are diamyl phthalate, dihexyl sebacate, dioctyl phthalate, dioctyl adipate, tricresyl phosphate, an ester from fatty acids of 7 to 9 carbon atoms and triethylene glycol, the diester from thiobutyric acid and 4-chlorbutanol-1, and the ester of pentaerythritol with fatty acids of 4 to 6 carbon atoms. Fillers specified are bentonite, kieselguhr, silica gel, wood meal, cork meal, and fibre or fabric dust.  The pastes may also contain small amounts of oily silicates to render the final products water repellent.  The driving off of the volatile liquid during the gelling process renders the coatings and foils porous, and this porosity may be improved by the addition to the polyvinyl chloride pastes of agents which liberate gas on heating such as ammonium bicarbonate, diazoaminobenzene, the monohydrazone of benzil, esters and amides of azodicarboxylic acids, azodi-isobutyric acid dinitrile, and azodi-hexahydrobenzoic acid dinitrile; these gas generating agents may be added to the pastes in solution, or the fillers may be impregnated therewith.
