Title: Improvements in or relating to electrical devices having envelopes fitted with caps
IPC: H01J5/60
Filed: 1952-06-05
Abstract: 728,963. Capping electric lamps and like devices. GENERAL ELECTRIC CO., Ltd., BREADNER, R. L., LEEDS, R. E., and SIMMS, C. H. June 5, 1953 [June 5, 1952], No. 14253/52. Class 39 (2). In securing a cap or base to the neck of a bulb or envelope of an electric incandescent lamp or similar device by providing one or more keys on the neck to interengage with corresponding parts on the cap to prevent relative motion of envelope and cap without the aid of cement, the neck portion is formed by blowing the heat softened glass thereof into a surrounding mould formed with inverse key portions or recesses and at the same time assisting the shaping of the glass into engagement with the surfaces of the said inverse key portions by applying suction at those surfaces. Fig. 3 shows a transverse section in a plane at right-angles to the axis of the glass neck 1 of a bulb and through four protuberances or pips 2 which are engaged within apertures 8 in the wall of a cap 3. The mould which is used in forming the protuberances 2 comprises two complementary parts 9, 10, each provided with two inverse key portions 11, 12 and 13, 14 respectively into which the softened glass of the neck is blown after fitting the mould around it. Chambers 15, 16 provided behind the respective pairs of inverse key portions communicate therewith through a number of channels 17, and each chamber is connected to an exhaust pump through connection 18 or 19, whereby suction is applied simultaneously with the application of air pressure to the interior of the bulb neck. In order to fit the cylindrical skirt 3 of a cap on to the neck 1 the skirt may be provided with holes 8, Fig. 6, located in positions to receive the protuberances 2, and with slits 24 which extend from the holes to the rim of the skirt and allow the rim to be pushed over the protuberances. The edges of the slits 24 may be subsequently welded or soldered together, or a locking ring may be provided to clamp them together. The securement of the cap may be strengthened by providing one or more short circumferential grooves 25 in the bulb neck during moulding, and slitting the skirt of the cap to form tongues 26 which are pressed into the adjacent grooves 25 after fitting the cap upon the neck. Rattling of the cap upon the neck may also be prevented by slitting the cap to form tongues 27 which are pressed inward to provide a resilient seating for the bottom of the envelope. In an alternative arrangement, Fig. 7, the skirt 3 is pressed out to form a pocket 28 which receives a protuberance 2 on the bulb neck, a transverse slit 29 being provided at or slightly below the level of the top of the protuberance 2 so that by pushing the face of the pocket inwardly at the part above the slit, the axial withdrawal of the cap from the envelope is prevented. The cap may be made of plastic material and attached by moulding in situ on the glass neck of the bulb.

Title: Process for the preparation of hydroxyterephthalic acid
IPC: C07C51/15
Filed: 1967-03-30
Abstract: Hydroxyterephthalic acid or its alkali metal salts are prepared by heating an alkali metal salt of m-hydroxybenzoic acid at temperatures above 230 DEG  C. with an alkali metal carbonate or bicarbonate and excess carbon dioxide and, if desired, converting the alkali metal salt thus obtained to the acid in known manner. It is desirable to mix the starting materials with finely-divided inert substances, e.g. sand, kieselguhr, silica, metal powders or turnings, finely divided metal oxides such as alumina, and inert salts such as sodium sulphate.  Preferably the reaction is carried out at superatmospheric pressure, e.g. 5-50 atm.  If desired a catalyst, e.g. cadmium oxide, may be present.  The salts may be converted to the acid by dissolving in water and treating the solution with acid, e.g. hydrochloric acid.
Patent GB-478624-A (GB)
Title: Manufacture of aminoaryl sulphones
Filed: 1937-05-26
Abstract: Aminoaryl sulphones are made by the action of ammonia under pressure on aryl sulphones containing a nuclear halogen atom but no nitro group.  The reaction may be effected in the presence or absence of a solvent and with or without addition of copper or a metal salt, such as a copper salt, as a catalyst.  Aminoaryl sulphones of the following types are so obtainable from the corresponding halogenaryl sulphones:--(a) 1 - aminophenyl - 2 - (or-4) - alkyl, sulphones, such as 1-aminophenyl-2-methyl--2-ethyl-, or -2-propylsulphone or 1-aminophenyl-4-ethyl sulphone, (b) 1-aminophenyl-2-(or -4)-benzyl sulphone, (c) 1-aminophenyl-2-(or -4)-aryl sulphones, such as 1-aminophenyl-2-phenyl or -2-tolyl sulphones, (d) 1-aminophenyl-2:4-di sulphones containing identical or different sulphone groups, such as 1-aminophenyl-2 : 4-dimethyl-, -2 : 4-diethyl-, -2 : 4-dipropyl-, -2 : 4-dibutyl-, -2 : 4-dibenzyl-, -2-benzyl-4-ethyl-, or -2-ethyl-4-phenyl disulphone, (e) aminoaryl sulphones containing additional substituents other than nitro groups, such as halogen atoms or alkyl, hydroxyalkyl, sulphonic or sulphonamide groups.  An example is given in which 1-aminophenyl-2 : 4-diethyl disulphone is prepared from 1-chlorophenyl-2 : 4-diethyl disulphone by reaction with aqueous alcoholic ammonia at 130--135 DEG C.  Chloroaryl disulphones for use as starting materials are obtainable by treating chlorobenzene with chlorosulphonic acid at a raised temperature to yield 1-chlorobenzene-2 : 4-disulphochloride, which is reduced, e.g. with zinc dust or sodium sulphite, to yield a salt of 1-chlorobenzene-2 : 4-disulphinic acid; the latter, in the form of an alkali salt, is condensed with methyl, ethyl, propyl, or butyl bromide or benzyl chloride to yield the corresponding disulphone. 1-Chlorophenyl-4-ethyl-2-benzyl disulphone is obtainable by treating chlorobenzene with chlorosulphonic acid in the cold to yield 1-chlorobenzene-4-sulphochloride, which is converted, by way of 1-chlorobenzene-4-sulphinic acid, into 1-chlorophenyl-4-ethyl sulphone; the latter, by treatment with hot chlorosulphonic acid, yields 1-chlorophenyl-4-ethyl-sulphone - 2 - sulphochloride, from which, by reduction and treatment with benzyl chloride, 1 - chlorophenyl - 4 - ethyl - 2 - benzyl sulphone is obtained.
