Filed: 1970-04-21
Abstract: 1302845 Capacitors GENERAL ELECTRIC CO 21 April 1970 [21 April 1969] 19005/70 Heading H1M A ceramic capacitor comprises at least one ceramic block 10 metallized on its opposite planar surfaces at 16 bonded to adjacent such blocks or to an end block 18, the periphery of the assembly having been machined to remove material so that the entire peripheral edges of the metallized coatings are precisely aligned with the periphery of the immediately adjacent ceramic material (Fig. 2, not shown). Because of the absence of electrical stresses due to misalignment or to the presence of metallizing on the peripheral surfaces (Figs. 4-8, not shown), an insulating coating on the periphery of the assembly may be as thin as 2 mils. The ceramic blocks may be barium titanate, the end blocks, which as shown are rings, ceramic or glass-reinforced epoxy resin and the metallizing silver. Conductive epoxy resin or silver solder may bond the metallized block together. The insulating coating may be epoxy, polyester or silicone resin. In a capacitor for an air-blast circuit breaker (Fig. 3, not shown) a pair or terminals, one spring biassed, bear against the outer metallized blocks within the end rings. In a modification (Figs. 9 and 10, not shown) single metallized blocks each having a pair of end rings are series connected by conductive buttons located within the end rings.

Title: Improvements in or relating to synthetic polyesters and products formed therefrom
IPC: C08G63/82
Filed: 1956-06-20
Abstract: Fibre- or film-forming polyesters having an improved affinity for basic dyes contain as a minor proportion of their structural units organic radicals having at least one sulphonate group in the form of a metal salt.  They are made by reacting a dicarboxylic acid and an aliphatic glycol or a diester of an aromatic diol in the presence of at least 0.5 mol. per cent based on the total of the acid components of a compound containing at least one ester-forming functional group and at least one sulphonate group in the form of a metallic salt. The compounds may be metallic salts of sulphomonocarboxylic esters, sulphodicarboxylic esters, monohydric and dihydric alcohols containing at least one sulphonic acid group, or monohydric alcohols containing one carboxylic acid group and one sulphonic acid group. Preferably such compounds have the formula <FORM:0826248/IV (a)/1> wherein <FORM:0826248/IV (a)/2> is the metallic sulphonate salt of a divalent arylene radical, M is the atomic equivalent of a metallic element, R is <FORM:0826248/IV (a)/3> and n and m are numbers and n being greater than 1, and R1 being a member of the same class as R or hydrogen. Polyesterification may be effected in the presence of ester-interchange catalysts (e.g. salts, such as the acetates, of calcium, manganese or lanthanum), polymerization catalysts (e.g. antimony oxide), colour inhibitors (e.g. alkyl or aryl phosphate esters) or delusterants (e.g. titanium dioxide or barium carbonate). The preferred polyesters to be modified are polyesters of diesters of terephthalic acid and polymethylene glycols which may if desired be further modified with other diesters (e.g.p.p1-bibenzoates) or other glycols (e.g. 1.4-bis [hydroxyethoxy] benzene).  Examples describe the preparation of polyesters from dimethyl terephthalate, ethylene glycol and (1), (5), (6) and (7) potassium, calcium, lanthanum or lead salts of 3.5-di (carbomethoxy) benzenesulphonate or sodium 1.8-di (carbomethoxy) naphthalene - 3 - sulphonate; (2) potassium 2.5 - di (carbomethoxy) benzene sulphonate; (3) sodium p - carbomethoxybenzenesulphonate; (4) potassium 4.41 - di (carbomethoxy) biphenyl - 2 - sulphonate; (8) dipotassium 5 - carbomethoxybenzene - 1.3 - disulphonate.

Title: Improvements in the manufacture of wire net glass and apparatus therefor
IPC: C03B13/12
Filed: 1931-07-03
Abstract: 381,228. Making wire-glass. PILKINGTON BROS., Ltd., 631, Tower Building, Water Street, Liverpool, and GASKELL, J., Stocks well, Hard Lane, St. Helens, Lancashire. July 3, 1931, No. 19202. [Class 56.] Relates to the method of making wire-glass in which wire net is drawn under tension into the glass sheet, or between glass strips which are welded together. According to the invention, the tendency of the wire net to move laterally relatively to the glass strip is counteracted by varying the position at which the retarding force that causes the tension is applied to the wire net. The invention is shown as applied to a rolling- apparatus in which a glass strip 2 is formed on a roller 1, and molten glass 3. flowing from a.spout 4 is rolled on to the strip 2 by a second roller 5, wire netting 6 being guided into the pass between the rollers by means of a guide roller 7. The roll 8 of wire net is supported by a shaft 10, and a rod 11, held in the frame of the apparatus, carries three arms 12 terminating in brake blocks 13 which rest on the roll 8. Weights 14 give the requisite pressure on the roll, but any of the arms may be raised by means of levers 18 each of which is connected to an arm 12 by a cord 15. By lifting one or more brake blocks from the roll, the tension in the net may be made unsymmetrical if required to correct lateral movement of the wire. In a modified construction, the wire is passed over an idle roller and the brake is applied to the net at its line of contact with the idler. The net may also be passed between pairs of rollers to which brakes may be applied. Alternatively, the desired retardation may be applied by deflecting either one edge or the other of the net from its normal course by means of a roller or the like.

Filed: 1936-07-13
Abstract: 457,321. Type-bar-making machines. INTERTYPE, Ltd., 215, Farnham Road, Slough, Buckinghamshire. July 13, 1936, No. 19389. Convention date, Dec. 24, 1935. Addition to 445,909. [Class 100 (iii)] Clamping matrices ;moulds.-The typebar-making machine described in the parent Specification for casting slugs having at one or both ends parts of decreased height is modified by making the continuous ribs 12, 13 on the vice-jaws 6, 7 so that they taper towards their outer edges to a width equal to the vertical width of the mould cavity 5, which has bevelled edges 21, 22 corresponding to the taper so that the ribs seal the front of the mould cavity beyond the line of matrices M. Close contact between the adjacent faces of the mould 3, 4 and the jaws 6, 7 is thus rendered unnecessary and a clearance space is therefore provided. The tapered form of the ribs and the cavityedges renders the ribs selfaligning. Specifications 14582/90, [Class 100], 402,809, 402,841, and 406,962 are referred to.

Title: Improvements in or relating to electric switches for railway and like signalling systems
IPC: H01H19/62
Filed: 1930-06-26
Abstract: 352,709. Snap - action switches; momentary-contact switches. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., Caxton House, Westminster, DOWNES, F., Arlow House, Arlow Road, Winchmore Hill, and ROGERS, W. D., Forres, Walpole Road, Tottenham, both in London. June 26, 1930, No. 19441. [Class 38 (v).] Latching.-In a railway signalling contact mechanism of the type comprising a rotatable drum carrying a number of cams for operating a series of contact springs, each cam consists of two parts arranged side by side on the drum in such manner that the parts are relatively adjustable to vary the length of the operative arc of the cam. The drawings show a contact mechanism operated by a bar provided with electromagnetic locking means. A set of cams 22, 23 are mounted between spacers 15 on a spindle 11. Each cam comprises two cam discs 22, 23 relatively adjustable on the spindle 11 and held by set-screws. In Fig. 4, the cam parts are shown extended to their greatest operative arc, and are arranged to operate, by means of spring-mounted insulators 9, contacts 5 connected to terminals 6, 8. The drum is rotated by means of a rectilinearly-moving operating-bar 4 with a rack which engages a pinion 16 on the spindle 11. A fixed rack 18 co-operating with a trailing pawl 19 pivoted at 20 to the bar 4, ensures that the bar cannot return until it has completed its movement in one direction. A locking device, Fig. 7, is provided for the bar 4. When the bar is moved in the normal course of operation, a position is reached when a pin 33 on the bar engages a cam 31 to depress a locking-dog 29 causing a cam 30 to engage a recess 32. At the same time, a lever 37 in a recess 38 causes an armature 35 of an electromagnet 34 to rotate anticlockwise. This moves a plate 39 so as to place a stop 40 over the dog 29 preventing it from rising, and thus locking the bar 4 against movement. An economy switch, Fig. 10 (not shown), comprising a pair of contact springs connected in series with the electromagnet is operated by means of a ball which, in the locked position, rests in a recess in the bar 4. If the circuit of the electromagnet is otherwise completed an attempt to move the bar forces the ball out of the recess and completes the circuit by means of the economy switch. The armature 35 then removes the stop 40 and lifts the locking-dog. The bar is then free to move until the locking-cam and the pin at the other end reach the locking- dog, and the ball of the economy switch falls into a second recess in the bar 4. The locking-plate 39 may also carry contacts.

If aluminium, is to be introduced into another metal, it is supported in a refractory container.
Patent GB-467376-A (GB)
Title: Process for the manufacture of unsaturated neutral oxidation products of stigmasterol compounds
Filed: 1936-07-13
Abstract: Unsaturated neutral oxidation products of stigmasterol which still contain the cyclopentanopolyhydrophenanthrene nucleus and the full side chain are prepared by the oxidation of esters of stigmasterol without intermediate protection of the double bond with oxidizing agents under mild conditions, followed by the separation from the oxidation product of the neutral fraction. Suitable mild oxidation conditions are obtained by the use of a dilute solution of chromic acid or potassium permanganate in glacial acetic acid at room temperature.  The oxidation conditions are further illustrated by reference to literature.  The products of the invention comprise neutral bodies which possess the nucleus and side chain of stigmasterol together with other oxygen containing groups, which may be keto groups.  The bodies which contain keto groups are separated from those which do not, by the usual ketone reage ts such as semicarbazide &c.  An alternative method for the separation of the neutral oxidation products is fractional crystallization.  In an example a glacial acetic acid solution of stigmasterol acetate is treated with a dilute glacial acetic solution of chromic acid and allowed to remain at room temperature for 3 days.  The product is diluted with water and extracted with ether.  The ethereal solution is extracted with alkali to remove the acid portion and the neutral portion which remains is isolated and fractionally crystallized.  The less soluble portion consists mainly of a hydroxy ketone which is purified by ketone reagents, while the more soluble portion consists mainly of a compound containing no keto group and having the empirical formula C31H50O5.
