Abstract: 662,308. Condensers. BRITISH THOMSONHOUSTON CO., Ltd. Aug. 15, 1949 [Aug. 26, 1948], No. 21228/49. Drawings to Specification. Class 37. [Also in Groups VIII and XV] The subject-matter of this Specification is very similar to that in Specification 662,306, [Group VIII], which is referred to. The only difference between the two Specifications is that in the present Specification a dab of adhesive is applied to the mounting strip a predetermined distance ahead of the conducting strip 8imultaneonsly with the cutting of that strip. The mounting strip is then advanced the predetermined distance whereby the severed part of the conducting strip is pressed on to an area of mounting strip coated with a dab of adhesive. The conducting strip is hence not coated with adhesive. Specification 657,951 also is referred to.

[Class 132 (ii)] A scoring device for a bagatelle or like game board having a plurality of pockets comprises a star wheel for each pocket and a single indicating device common to all of said star wheels and in driving connection therewith, said star wheels being actuated by a ball impinging on one of the arms of the star wheels. In the construction shown in Figs. 1 and 2, a ball projected on the table A falls through a hole B into a tube C to strike one of the arms E of a star wheel rigid with the spindle D and sprocket wheel F to rotate through the chain G the sprocket wheel H which through the ratchet and pawl mechanism K rotates the shaft J and the scoring dial L secured thereto. A portion of the rim of the dial L projects through a slot in the gameboard for its indications to be read against a pointer M on the edge of the slot. A plate spring O bears on a squared collar on the spindle D and stops rotation of the spindle after each actuation thereof. A star wheel is provided for each hole in the board actuating by different ratio gearing a separate wheel H on the shaft J, the dial L showing the total score. There may be two or more shafts J each actuated by a group of spindles D and each connected to the scoring dial by appropriate gear including a pawl and ratchet coupling. The chain and sprocket gear G, F, H can be replaced by spur gearing. The release of the balls and zeroizing of the dial L may be coin-controlled. A boss, stud or arm may be mounted on the shaft J so that in a predetermined position it delivers a token to the player.

Abstract: 1304133 Colour television tubes PHILCO FORD CORP 19 April 1971 [2 March 1970] 21321/71 Heading H1D In the manufacture of a multi-dot or multiline colour television screen by exposure of a photo-resist through a shadow mask or grid which is subsequently used in the completed tube, the exposed areas are made smaller than the corresponding apertures in the mask or grid by covering the latter with a plastics sheet which is drawn into the apertures to form lenses which focus the incident light. The sheet may be a copolymer of ethylene and methylacrylic acid or a plasticized vinyl sheet about 15-20 mils. thick. When the shadow mask has conical apertures tapering from 16 to 25 mils. in diameter the sheet may be laid over the mask and heated whilst suction is applied to the opposite side of the mask (Fig. 2, not shown). When the mask is in the form of a grid, e.g. of parallel wires, a sheet of plastics material may be pressed against the grid by a backing-plate whilst being heated; the heating may be applied uniformly to the whole sheet (Fig. 6, not shown) or may be applied by an elongate source parallel to the wires which is moved transversely of the grid (Fig. 6A, not shown) so that portions of the sheet are heated sequentially. The grid may be removed and the deformed plastics sheet may be used alone in processing the screen.

Patent GB-202997-A (GB)
Title: Improved process for the manufacture of resin-like products
IPC: C08G8/00
Filed: 1923-08-23
Abstract: Resinous substances are produced by subjecting an organic halogen compound to prolonged heating with an aromatic hydrocarbon or a derivative thereof in the presence of aluminium magnesium silicates, such as Fuller's earth, franconite and tonsil, in quantity normally not exceeding 10 per cent of the total mass. The reacting materials are the same as in the Friedel-Crafts' reaction.  According to the examples, resinous bodies are obtained by (1) heating a mixture of naphthalene and naphthalene tetrachloride containing a little Fuller's earth, (2) heating acetyl chloride with naphthalene and some franconite, (3) boiling acetylene tetrachloride with xylene and Fuller's earth and (4) heating naphthalene tetrachloride with the phenolic bodies from low-temperature tar in the presence of Fuller's earth.  In each case the product is dissolved in a suitable solvent, the solution shaken with water, the solvent eliminated and the residue then decolourized, if desired, with Fuller's earth or the like.  The Specification, as open to inspection under Sect. 91 (3) (a) describes also the production of viscous or resinous substances from Friedel-Crafts' reactants (excluding alkyl-benzene halides) by heating them in the presence of a metal, a metallic compound or a porous substance; the temperature conditions, the proportions of the reacting materials and nature and quantity of the catalyst being so selected as to favour the formation of the resinous by-products of the reaction.  Examples are also given in which (1) naphthalene and naphthalene tetrachloride are heated in the presence of iron oxide, (2) acetyl chloride is heated with naphthalene and some anhydrous iron chloride, (3) chloroform is boiled with toluene or heated with naphthalene in the presence of anhydrous aluminium chloride, (4) acetylene tetrachloride and xylene or ethylene dichloride and toluene are boiled with aluminium chloride, and (5) naphthalene tetrachloride is heated with the phenolic bodies from low-temperature tar in the presence of iron oxide.  This subject-matter does not appear in the Specification as accepted.
