Title: Improvements relating to voltage transformers
IPC: H01F27/40
Filed: 1944-12-18
Abstract: 584,818. Switchgear structures. DAVIES, D. R., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Dec. 18, 1944, No. 25414. [Class 38 (v)] [Also in Group XXXV] A transformer with a resistance and/or a fuse in circuit is in a main casing having an opening through which the resistance and/or fuse on a mounting can be moved into an auxiliary chamber where they are electrically and physically isolated from the transformer and where the opening is substantially closed by the mounting. A transformer 1 is mounted in a casing 3 in which is a terminal 30 to which are connected a conductor 31 from associated switchgear and a conductor 32 connected to the controlled circuit. The transformer primary is connected at one end to terminal 28 and at the other through a resistance 16 mounted in clips 15 in a base 10b and a fuse (not shown) similarly mounted to the terminal 30. This circuit is made when two contacts such as 21 rest in engagement with two contacts 'such as 23. A spider 9 carries on rods 8 a hood 10a to which is attached the base 10. This structure may be moved upwards into the chain-dotted position, where base 10 is inside an auxiliary casing 4 and substantially blocks aperture 6 between the main and auxiliary casings. In this upper position contacts 21, 23 no longer engage and the resistance 16 and fuse are physically isolated from the transformer circuit. When the hinged lid 17 is opened the base 10 may be slid right out. Threads 11b, 11a on a rod 11 rotated by a head 12 engage in a boss 4b in the top of casing 4 to keep the movable structure in the lower and upper positions respectively. When the movable structure is in the upper position an interlocked cover 36 may be swung open to allow the passage of a testing bushing 35. In an alternative construction described, Figs. 3, 4 (not shown), the resistance and fuse mounting is moved upwards by movement of a pivoted handle which is mechanically interlocked with the inspection cover so that the latter can only be opened when the mounting is in the upper position.

Title: Synthetic resins and their manufacture
IPC: C08G77/445
Filed: 1953-09-15
Abstract: Synthetic resins, suitable as baking resins, are made by heating at 150 DEG  to 275 DEG  C. a methyl- or methylphenyl-polysiloxane containing hydroxyl groups with a polyester derived from a polyhydric alcohol and phthalic acid, adipic acid and/or maleic acid in proportions such that the number of alcoholic OH groups is at least 40 per cent in excess of the number of COOH groups.  The two resins may be mixed together by means of a solvent and the solvent removed prior to heating.  In the example a siloxane, containing 4 to 6 per cent OH groups, is made by hydrolysing dimethyldichloro-, diphenyldichloro-, phenyltrichloro- and methyltrichlorosilanes in butylacetate and butanol, and heated with a polyester made from phthalic anhydride, trimethylolpropane and ethylene glycol.  Glycerol may also be used for making the polyester.  Hardening of the resins may be accelerated, e.g. by lead naphthenate.  Specification 583,754, [Group IV], is referred to.

Title: Improvements in or relating to apparatus for inserting articles into bags
Inventor: COOKSON HAROLD
IPC: B65B5/06
Filed: 1958-08-08
Abstract: 876,873. Packaging. METAL BOX CO. Ltd. July 16, 1959 [Aug. 8, 1958], No. 25590/58. Class 94(1). Apparatus for inserting articles into bags comprises guides, supported side-by-side and adapted to form two outer channels 1, 2 and an inner channel 3 along which a row of articles in each of the outer channels and at least one row of articles in the inner channel can be moved lengthwise into a bag fitted about the guides, a pusher 16, to insert the articles into the bag and to remove the loaded bag from the guides, and a movable carriage 8 on which one of the guides is mounted whereby it may be moved towards the other guide to facilitate the fitting of a bag about the guides. The guides may comprise T-sectioned members arranged as shown in Fig. 3 to form the inner and outer channels, or L-sectioned members similarly arranged, and the members may be mounted for relative adjustment to accommodate articles of different sizes. Alternatively the channels may be non-adjustable and formed of U-sectioned members back-to-back. The flanges 4 are bagengaging sides and the webs 5 are aligned to form the channels. The articles are grouped, to be led into the channels, by collating members 15 which extend backwards from the guides and, while the pusher 16 is operating, the articles in the outer channels are held by spring guide plates 24. The pusher 16 is connected to a link 17 which is pivoted at 18 and connected to the piston of a pneumatic cylinder 20. Operation of the piston is controlled by a handle 21 and the pusher is constrained to move in a substantially straight line path by rollers 22, on the link 17, running in tracks 23. The guides are brought together when a handle 11 is swung about its pivot 12 and so, through links 9, moves the carriage 8 inwards until the links meet an adjustable stop. A row of articles, e.g. cartons, is placed in each of the outer channels 1, 2 and the bag is fitted over them. The handle 11 is then swung back, moving the outer rows apart and distending the bag. Cartons are then assembled between the collating members 15 and the pusher 16 is operated to push the inner rows between the outer rows in the bag and to eject the loaded bag from the guides. In a modification, the movable guide is spring-urged towards the fixed guide and is moved away by the pusher.

Title: Improvements in and relating to ion-exchange resins
Inventor: LINDSEY ALAN SIDNEY
IPC: B01J41/08
Filed: 1957-08-14
Abstract: Anion exchange resins having complexing properties are obtained from a solid intermediate prepared by treating pyridine with an alkali metal and treating the product with dry carbon dioxide (see Group IV(b)), by treating said intermediate in aqueous solution with an acid, e.g. HCl, separating the resulting precipitate and exposing the same to air to give resin Pa ; resin Pb  is obtained by evaporating the filtrate after removing Pa  to dryness.  Pa  may be treated with methyl iodide or sulphate followed by aqueous sodium hydroxide and water washing to give polymers of higher equivalent weight with similar properties.ALSO:A solid intermediate which may be used for the preparation of anion-exchange resins (see Group IV(a)) is prepared by treating pyridine with an alkali metal and treating the product obtained with dry carbon dioxide.  The alkali metal is preferably suspended in a mixture of an inert hydrocarbon and an ether such as dimethoxyethane or tetrahydrofuran or a nitrogen-containing compound such as an excess of pyridine.  The solid intermediate, where sodium is used, is believed to consist of compounds of formulae <FORM:0910147/IV (b)/1> where R is H or Na. The provisional Specification discloses and exemplifies similar reactions with quinoline and isoquinoline.

Title: Apparatus for separating and individually dispensing small elongate parts
IPC: B65G47/14
Filed: 1971-04-19
Abstract: 1338137 Orienting and feeding articles VEREINIGTE DRAHTWERKE AG 19 April 1971 [7 April 1970] 25699/71 Heading B8S Rod-like articles are singled out and oriented by a rotating drum 22, Fig. 2, provided with a recess 26. The drum rotates at such a speed that the heap of articles remains at the bottom, but the one article in the recess 26 is carried upwards and held in position by centrifugal force. When the drum reaches the position shown in Fig. 5, the article drops out through a slot 28. Figs. 9, 9a illustrate how asymmetrical articles are oriented by means of a shallow recess 26. An agitator 31, Fig. 10, is provided for bolt-shaped articles. Fig. 11 shows a drum provided with a plurality of grooves 36 in each of which an article is oriented. The outlet slots may be adjacent each other so that the articles are discharged simultaneously, or they may be staggered to provide sequential discharge. Fig. 12 shows an embodiment in which the speed of rotation of the drum 33 is controlled by a cam disc 44 and a follower 54 which controls the driving motor. Articles are discharged down a shoot 47 when a flap 43 covering the discharge orifice is raised by a cam 39 and follower 41. The drum is slowed down as the recess passes through the heap of articles at the bottom, slightly decelerated when the recess is at the highest point of its travel and decelerated again when the recess is adjacent the discharge shoot. The cam disc makes one revolution for two revolutions of the drum. Thus, articles are discharged only during alternate revolutions of the drum.

Abstract: 659,095. Phase-changing. SADIR CARPENTIER. Oct. 4, 1948, Nos. 25843, 25844 and 25845. Convention dates, Oct. 4, 1947, Dec. 26, 1947, and April 1, 1948. [Class 38 (ii)] [Also in Groups XXXVI and XL (c)] A network for phasechanging comprises a number of rectangular meshes of transmission line arranged in ladder - like fashion, a connection being made to each junctionpoint on one side of the ladder by one conductor of a polyphase system, and single phase connections being made to the extreme junctionpoints on the other side. In the example shown the network is made up from coaxial lines, the outers of which are all earthed and are not shown in the drawings.. Single-phase sources 1 and 2 are connected between earth and the extreme points 3 and 5 of one side of the network. A three-phase load 9 is connected to the other side. By a suitable choice of the impedance and electrical length of the lines of the network, if either source is in operation it forms a balanced system with the load 9 and neither source can react on the other. As can be seen the number of meshes is one less than the number of phases required. Specification 19193/48 (as open to inspection under Sect. 91) is referred to.

Title: Improvements in and relating to wick cleaning devices for wick burners
IPC: F21V37/00
Filed: 1922-09-26
Abstract: 213,294. Marks, E. C. R., (Cleveland Metals Products Co.). Sept. 26, 1922. Wicks, cutting, cleaning, and trimming.- Wick-cleaning devices for burners having means for limiting the upward movement of the wick, comprise char removing means and means cooperating with part of the wick limiting means to locate the char removing means in a position to remove a definite amount of char when the wick is in its elevated position. Modifications are included for burners of different sizes. In the form shown in Figs. 1 and 1<a> for a burner of the kind described in Specification 206,545, the cleaner comprises a body portion 60 and a wick engaging flange 66 which forms a char collecting trough with an inclined wall 63. At opposite sides of tangential slots 67 spread about the flange are cutting edges 69 and upwardly curled smoothing portions 68. A channel member 70 applied to the underside of the flange forms a wick sizer. The wick is first raised to its high position and the flame-spreader removed, the cleaner then being inserted so that its bottom flange 65 bears upon the annulus 25, in which position the wick engaging flange bears with sufficient pressure upon the wick. The cleaner is then rotated backwards and forwards a distance somewhat greater than that between the slots 67. In the form shown in Fig. 7 the cleaner is rotated by means of a crank 88 and the wick is cleaned by blades 92 and smoothed by tapered rollers 91. In other modifications the wick is sized by loops of strap metal depending from a wick engaging flange and the cleaner is rotated by means of a knob; also the cleaner may include char removing means of different sizes for use with stoves employing two sizes of burners. A further cleaner shown in Figs. 9 and 10, itself incorporates means for bringing the wick stop means into operation, obviating the use of the flame-spreader for this purpose. The device comprises two relatively movable units A, B. The first includes a body 95 having a shoulder portion 46a for engagement by locking elements 41 spread apart by a pin 48<a> and a base flange 96 supported on the annulus 25. The second unit B comprises a wick engaging flange 100 with wick sizer 102, which is carried by a sleeve 101 loosely surrounding the lower portions of the unit A. A member 97 having a series of depending prongs 98 adapted to extend through slots 107 in the flange 100 is attached to the body 95 for rotation relatively thereto and is prevented from rotating relatively to the sleeve by a finger 105 extending through a slot 106 in the member 97. The cleaner is inserted when the wick is down and the unit A is looked to the frame 26. The flange 102 rests on the wick tubes. When the wick is raised it engages the prongs and lifts the unit A and frame 26 to bring the wick stop means into operation whereupon the body 95 is lifted to the position shown in Fig. 10, the base flange 96 picking up the sleeve 101 and lifting the flange 100 to the high position of the wick which follows until it is engaged by the flange.

Abstract: Diols of the general formula <FORM:0897335/IV (a)/1> wherein R is a divalent organic radical other than diphenyl propane and n and n1 are integers, are poly-condensed with ethylenically unsaturated dicarboxylic acids to form polyesters which are copolymerized with compounds containing a =C=CH2 group.  Several diols from which R may be derived are mentioned including aliphatic, cycloaliphatic, alkyl-aromatic, aromatic and heterocyclic compounds any of which may contain hetero-atoms, e.g. ethers, thioethers and sulphones. Unsaturated dicarboxylic acids specified are fumaric, maleic, itaconic, citraconic, mesaconic and glutaconic.  The polyester may also contain some saturated aliphatic or aromatic dicarboxylic acid and the specified diol may be supplemented by another dialcohol or diphenol.  Polyesterification may be effected by the usual processes, e.g. at 120 DEG  to 220 DEG C. under an inert gas atmosphere using benzene to entrain the water formed azeotropically.  Comonomers specified are styrene and its homologues, diallyl phthalate and vinyl acetate. Copolymerization may be catalysed by cyclohexanone or MEK peroxide or cumene hydroperoxide and accelerated by cobalt octanoate, naphthenate or resinate.  An inhibitor, e.g. hydroquinone may be used to prevent premature polymerization.ALSO:Diols of the general formula <FORM:0897335/IV (b)/1> where R is a divalent organic radical other than 2,2 diphenyl propane and n and n1 are integers are used in the preparation of unsaturated polyester resins (see Group IV(a)). They may be prepared by condensing at least 2 moles of 1,2-epoxy cyclohexane with one mole of a diol R(OH)2.  Such diols may be aliphatic, cycloaliphatic, alkyl aromatic, aromatic or heterocyclic. The aliphatic chains, or aromatic nuclei, thereof may be linked through hetero atoms.  Examples of such diols given include glycols, glycol ethers and thioethers, p  bis(4-hydroxyphenyl) sulphone, 3, 3 - bis (hydroxymethyl) oxetane and 1,4-bis(hydroxyethyl) piperazine. Condensation may be effected in a homogenous liquid phase containing the reactants alone or in solution, e.g. in an aromatic hydrocarbon, at 100 DEG C. to 200 DEG C. using a catalyst such as an alkali metal or alkaline earth metal hydroxide or a Friedel-Crafts halide.  The epoxy compound is preferably used in 1 to 2 moles excess and may be added initially or progressively.  In specific examples 1,2-epoxy cyclohexane is condensed with ethylene glycol (1 and 2); hexane-1,6-diol(3); 1 - phenyl - 1, 2 - dihydroxy - ethane (4); 2, 2 - bis(4-hydroxy cyclohexyl)propane (5); hydroquinone (6); and bis(4-hydroxyphenyl)sulphone (7).
