Title: Improvements in or relating to electrical switchgear
IPC: H02B11/133
Filed: 1925-05-19
Abstract: 257,010. Reyrolle & Co., Ltd., A., and Coates, F. May 19, 1925. Sliding switch-carriage arrangements; electromagnetic switches; switches, quick-action. - Sliding carriage switchgear arrangements for automatic substations are provided with a number of auxiliary switches mounted on the fixed switchgear portion with their actuating mechanisms and arranged so that when the draw-out portion is in its closed position the operation of the main switch contacts actuates also the auxiliary switches. In the form shown in Fig. 1 in which the auxiliary switches are mounted on the fixed structure and are operated mechanically through a link F attached at one end to a crank F<1> on the switch spindle and at the other to a downwardly-pressed spring plunger E carrying a roller at its lower end. The draw-out portion A is fitted with a sliding rod D connected at one end through a bell-crank C<1>, C<2> to the actuating mechanism A<4> of the main switch A<1>. The other end of the rod D has an inclined face D<2> which is brought near to the roller on the arm E when the member A<1> is moved into position so that on subsequent closure of the main switch the plunger E is raised and the auxiliary switches operated through the link F. When the auxiliary switches are operated electromagnetically as shown in Figs. 3 and 4 they are mounted on a shaft M together with switches G<2>, G<3> controlling the circuits of solenoids H, H<1> which are provided for rocking the shaft in opposite directions. The cores of the electromagnets H, H<1> are secured to arms K, K<1> of a pivoted lever which has a third arm L with a pin-andslot connection to a lever L<3> loosely mounted on an extension of the shaft M. This extension also carries a lever N pivotally secured at one end to a dead-centre spring O, lost motion connections N<1>, N<2> being provided between levers L<3> and N and lever N and the shaft M. When the main switch J, Fig. 5, is closed, it moves over a change-over switch J<1> and completes the circuit of electromagnet H through switch G<2>. The electromagnet H then moves over the shaft M with a snap-action, breaking its circuit at switch G<2> and preparing a circuit for the electromagnet H<1> through switch G<3> which is closed on the opening of the main switch. The auxiliary switches are mounted in a base G secured to the fixed switchgear portion, the switch J<1> being carried on the draw-out portion and connected to its controlled circuits by an additional threepin plug coupling. The contacts of the auxiliary switches may be arranged as required and some of these switches may be arranged to operate with a suitable time-delay action.

Title: Improvements in or relating to looms for the simultaneous production of two fabrics
IPC: D03D41/00
Filed: 1925-05-19
Abstract: 248,600. John, A. May 19, 1925. Two or more fabrics, looms specially designed for; breast beams; warps, tensioning and guiding. -The warps a, e for separate fabrics pass from a common warp beam b over a guide beam c and the fabrics pass over separate breast-beams d, g to a common beam l. One set of warps passes over a movable intermediate guide beam f, the corresponding breast-beam g being also movable. If the weft of the warps a breaks, the warps c will be woven a few more picks before stopping; to adjust the warps before re-starting, the warp and cloth beams are turned back, to bring the warps a into position, and then the beams f, g are moved in opposite directions to bring the warps e back into position. If the weft for the warps e breaks, it is only necessary To move the beams f, g. The beams f, g are adjusted by hand wheels which, through worm and bevel gearing, shift the beam bearings on screwed rods.

Abstract: 528,361. Hair waving appliances. FOX, J. B. May 5, 1939. No. 13427. [Class 39 (iii)] An electrically heated hair waving appliance comprises a fireproof glass tube a having a cup c at one end and closed at the other end. A fireproof glass tube d of smaller diameter contains a heating wire e and is enclosed in a metal tube or tinfoil sheath f connected at g to the wire e. A metal terminal member h is fitted around the tube f, and a further metal member i with a split flange i<SP>1</SP> fits over the member h to which it is secured by setscrews j. The member h is secured by cement k. Electrical connections are taken to sockets m, n in a housing o of insulating material.

Filed: 1937-05-11
Abstract: 495,334. Printing-surfaces. SCHLESINGER, A. May 11, 1937, No. 13452. [Class 100 (ii)] In the preparation of lithographic printing- plates, wherein, after the application of the image, a layer of varnish is applied, removal of the varnish at the required parts is facilitated by treating with a weak solution of a solvent. The 'varnish layer is relatively thicker over certain parts of the plate, and the solution acts to remove the varnish layer to a relatively less extent over these portions and so facilitates its removal with the protecting-layer on the plate. The varnish contains little or no greasy layer and may consist of shellac, celluloid lacquer, copal, or asphalt. The treating-solution is preferably a mixture of one part of spirit with 99 parts of water, castor oil, glycerine, oil of turpentine, or calcium chloride solution. If particularly hard resins are employed in the varnish, the plate may be first washed with the solution. If a plate requires renewal of the image, it is gummed, dried, washed with turpentine and then with the solution, coated with varnish, washed with the solution, and the layer of gum finally removed.

The core comprises a major proportion of a filler of small particle size and 10 to 50% by weight of a partially condensed thermosetting resin, and is formed by heating and compressing a dry mixture of powdered resinous binder and filler. The sheet material may be paper, woven or unwoven fibre, glass fibre, cloth or plastics material. The filler may be bagasse, diatomaceous earth, sawdust, powdered asbestos, powdered shive waste, maize husks or straw. The binder may be a phenol-formaldehyde, urea-formaldehyde or melamine-formaldehyde resin. As shown, an endless belt of wire mesh is supported on rollers 2 and 3, of which the latter is heated. A web 14 of sheet material is fed on to the belt and a dry mixture of filler and binder dropped on to it from the hopper 4. Plates 5 and 6 meter the mixture, and are adjustable. Plate 5 reciprocates horizontally and plate 6 vertically. Heating elements 7 above and below the belt may be electric strip heaters, induction heating elements or steam-heated platens. The pressing device 8 comprises a second wire-mesh belt 9 running over a heated drive roller 10 and another roller 11. The lower run of the belt 9 is inclined as shown, and co-operates with a rigid support 12 below the lower belt. The second web 16 of sheet material is pressed on to the core layer, and the product comes out on to a cutting table 17, where it is cut by a knife 18. It may then be further cured in a heated press under light pressure.
