Patent GB-612070-A (GB)
Title: Improved method of producing translucent and opaque polymeric material
IPC: C08F291/00
Filed: 1946-05-17
Abstract: Translucent, opalescent or opaque polymeric material is prepared by forming a solution comprising a polymer of styrene or an interpolymer of styrene with up to 90 per cent by weight of the interpolymer of an alkyl ester of acrylic, methacrylic or chloracrylic acid and a liquid monomeric alkyl ester of acrylic, methacrylic or chloracrylic acid, or a mixture of two or more such esters, or a liquid or syrup partial polymer of such ester or esters, the said polymer or interpolymer of styrene having a different refractive index to that of the polymer or interpolymer obtained from the liquid monomeric ester or esters alone, the solution being polymerized to the solid state.  Alkyl esters specified are methyl methacrylate and ethyl acrylate.  After forming the solution the polymerization may be completed in aqueous emulsion using starch as emulsifier.  Benzoyl peroxide may be used as catalyst, and specified dyes may be incorporated.  The process is preferably used in casting sheets of the polymeric material.  After polymerizing to the solid state the polymeric material may be subjected to further heat treatment. Specifications 427,494, 566,760, 573,115, and 588,576 are referred to.  In the Provisional Specification mention is made of the use of a low molecular weight polystyrene obtained by heat treatment of a high molecular weight polymer.

Title: Improvements in or relating to rolled metal bars and in means for their production
IPC: B21B1/08
Filed: 1929-05-14
Abstract: 325,436. Simpson & Co., Ltd., F. R., and Melhuish, J. W. D. May 14, 1929. Rolling flanged bars.-Flanged bars, particularly those for window frames, are rolled by four coacting rolls, one or both of the side rolls being exchangeable for rolls having a cutting rib of buttress form or having a patterned surface or having both of these features. A number of varying sections may thus be rolled in the same stand. In one form the side roll 4 has a cutting- rib 5, and the part of the flange beyond the groove formed on the section is intended to be broken off. The roll may be axially adjustable to vary the position of the groove. Either or both flanges may be grooved as in Fig. 5. Die-rolling.-In addition to the rib the roll may have a fluted or otherwise patterned surface. Both side rolls may be of the character described.
Patent GB-354825-A (GB)
Title: Manufacture of compounds containing aluminium and fluorine
IPC: C01F7/48
Filed: 1930-05-15
Abstract: Solutions containing the complex AlF3.AlCl3 obtained, for instance, as described in Specification 354,824, are treated to precipitate compounds containing aluminium and fluorine.  An acid fixing agent such as a carbonate or hydroxide of an alkali or alkaline-earth metal may, for example, be added to precipitate a basic aluminium fluoride which may correspond to the formula Al(OH)3.AlF3.  Any alkaline-earth metal salt present may be precipitated and separated first, for instance as calcium sulphate.  Alternatively a solution freed from alkaline-earth metal salts may be treated with an alkali fluoride to precipitate a double fluoride, which may correspond to the formula NaAlF4.

Title: A new or improved method of and means for cleaning the barrels of shot guns
IPC: F41A29/02
Filed: 1954-05-21
Abstract: 740,067. Cleaning the barrels of shot guns. BAXENDALE, G. V. May 21, 1954, No. 15026/54. Class 119 For cleaning the barrels of shot guns, an annular felt wad H, Fig. 1, is mounted on a brass spindle A between wooden distance pieces G and the assembly clamped between a shoulder B and a nut D, the shoulder B having a screwed spigot E for engagement by a ram rod and on the opposite end F of the spindle is loosely mounted a thin cardboard washer I. The whole assembly, attached to a ram rod, is then pushed down the bore until it projects beyond the end of the barrel and upon withdrawal the washer I, which has scraped the spent powder out of the barrel, falls off the sprindle and the felt wad H partially polishes the bore. For the final cleaning and polishing operation, a number of felt wads H, Fig. 2, are mounted on the same or a similar spindle A and this assembly reciprocated several times up and down the barrel. Specification 454,907 is referred to.
Patent GB-276606-A (GB)
Title: Improvements in the manufacture of blown glass articles
IPC: C03B9/12
Filed: 1927-06-07
Abstract: 276,606. Haddan, R., (Corning Glass Works). June 7, 1927. Blowing. - A method of making blown glass articles consists in forming a Rowing stream of glass into a ribbon, depositing the ribbon on a conveyer formed with apertures, allowing part of the ribbon to sab through the apertures, and then blowing in moulds the parts of the glass that have sagged through the apertures, the rib. bon and moulds being in continuous movement during the blowing- operation. The molten glass flows in a continuous stream 78, Fig. 46, from an aperture in a forehearth attached to a tank furnace, the rate of flow being controlled by a plug. The stream 78 passes between watercooled rollers 71, '72, by which it is flattened into a ribbon 79. The ribbon is deposited on a continuously moving conveyer 150 consisting of a series of plates 153 carried by the links of an endless chain which moves in an horizontal plane. In an alternative construction, two sets of plates are carried by similar chains so arranged that pairs of plates come together end to end below the rolls 71, 72 and move forwards as though they were single plates. Each plate is formed with an aperture 156, and as soon as the ribbon is deposited on the conveyer, the glass over the aperture commences to sag downwards, as shown. The edges of the apertures limit the amount of glass which is available and also serve to anchor the ribbon on the conveyer. The travel of the conveyer brings the ribbon under the run of an endless chain of blowheads 202 which, during the lower part of their run, make contact with the underside of a blow box 201. The blowheads are pressed into contact with the glass, ribbon above the apertures 156, and are supplied with air in regulated quantities from the blow box by means of valves or ports. The sagging glass expands progressively and each bulb so formed is enclosed in a mould 280. The apparatus described is intended particularly for the production of electric lamp bulbs. although it can be adapted for the production of other kinds of ware. The moulds 280 are carried by an endless chain moving in a vertical plane, and they are provided with means for opening and closing them automatically. They are also provided with means for rotating them while they are closed in order that the ware may have a high finish and be free from mould marks, When a bulb is blown, the mould opens and moves downwards, as shown in Fig. 47, the blowheads are lifted and move urpwards, and the bulbs continue to move forwards suspended from the conveyer. A disc 352 strips the glass ribbon from the plates of the conveyer and the bulbs are knocked-off by an arm 354. An air blast is provided to cool the blowheads, and jets of water are sprayed on to the moulds and conveyer plates during the inoperative parts of their run.

Title: Improvements relating to electric lamp holders for fluorescent lamps
IPC: H01R33/08
Filed: 1958-05-13
Abstract: 891,151. Lamp caps and holders. THORPH Ltd., F.W., and THORPE, F. W. Aug. 13, 1959 [May 13, 1958], No. 15255/58. Class 38 (1). A lamp holder for fluorescent lamps comprises springs 20 for urging contacts 13 into engagement with pins 14 of a lamp 15, the contacts 13 being housed within a plug 8 of elliptical crosssection which is urged towards the cap 16 of the lamp by springs 22 which embrace springs 20. To ensure that the springs of each pair work freely and independently, they are wound clockwise and anti-clockwise respectively. The inner springs 20 connect the contacts 13 to terminals 11 and an earthing contact 31 is secured to a wiring block 6. The plug 8 has a projection 25 to facilitate movement by an operator of the plug within a bore 9 and against the action of the springs 22. Movement of the plug is limited by a screw 27 of which the tip engages in a groove 29. The length of the pins 14 is so chosen that if a lamp supported in two such holders is moved longitudinally in either direction, the displacement is insufficient to allow removal of the lamp from the holders. When authorized removal of the lamp is desired, the lamp is moved in one direction to further stress the springs 22 of one lamp holder, and the projection 25 of the other holder is moved in the opposite direction. The plug 8, taking with it the contacts 13, is thus disengaged from the lamp cap and the lamp is free for removal, Fig. 2.
