Title: Controlling synchronous movement of electric motors
IPC: G05D3/14
Filed: 1942-08-24
Abstract: 559,692. Control of several motors. KENT, Ltd., G., GROUT, J. A. M., WARMINGTON, R. W., and BUCKLEY, G. Aug. 24, 1942, No. 11909. Drawings to Specification. [Class 38 iii)] When each of a number of motors effecting simultaneously similar operations reaches a given stage a contact controlled by the motor stops it and an arrangement of relays provides for simultaneous restarting only when all the motors have reached the same stage. If the motors are reversible the arrangement is such that only motors that, prior to reversal, have reached a synchronizing stage will be reversed, one remains inoperative until the others reach a synchronizing stage. In the system described the alternative field windings of each of a number of reversible motors are connected to forward and reverse running bus bars by individual relays which are normally actuated. When a master reversing switch is closed to energize one or other bus bar the motors operate simultaneously. Each motor or the mechanism or gearing which it drives actuates a cam to close a switch periodically, the arrangement being such. that a corresponding closure of all switches should occur simultaneously after a given run. An auxiliary relay associated with the motor concerned opens the circuit of its individual relay and prepares an alternative circuit therein which does not close until a common relay has had each of a number of parallel short circuits on its operating winding removed by the operation of all the auxiliary relays whereupon all the individual relays energize simultaneously to restart the motors. Relays are energized from the forward and reverse bus bars respectively to actuate a switch which causes a further relay to change over the alternative circuits referred to and prevent loss of correspondence of the motor action when reversing. Any motor may be isolated from the system by providing switches in the motor circuit or coupled switches in the circuit of the relays. Individual operation of any motor &c. may be obtained by a reversing switch linked to switches isolating its relays. The master switch may be actuated automatically as by a change in steam boiler output and the motors may actuate dampers.

Title: Laminated, flexible, fabric-like material made of rayon fibres
IPC: D04H5/06
Filed: 1951-05-23
Abstract: 691,888. Agglutinated fibrous sheets; compound sheet materials; rollers. MINNESOTA MINING & MANUFACTURING CO. May 23, 1951. [June 3, 1950] No. 12053/51. Classes 42 (ii) and 140. A laminated flexible fabric-like material consists of a layer of parallel yarns of non-plasticised, continuous, cellulose acetate filaments laminated by autogenous bonding to a web consisting of a compacted carded mixture of staple viscose rayon fibres and staple plasticised cellulose acetate fibres. The plasticised cellulose acetate fibres are in the proportion of 50 to 65 per cent. by weight and are autogenously bonded at their crossing points, e.g. as the result of hot-pressing, to form a network within which the viscose rayon fibres are distributed. The laminated material is irnpregnated with a flexible, water-resistant sizing that superficially coats the yarns without stiffening the material. A carded or gametted web 10, Fig. 2, containing a mixture of viscose rayon staple fibres and plasticised cellulose acetate staple fibres, is compacted by causing it to pass around part of the circumference of a rotating polished, heated drum 11, against which it is pressed by soft rolls 12 and 13 which consist of sheet metal cylinders upon which are wound five turns of smooth, finely woven glass cloth. The compacted web is stripped from the heated drum with the aid of an air-jet 15, passes around a wood roller 14, between steel pull rolls 16, 17 and is wound up at 18. To make the. laminated material, the resulting compacted carded web 26, Fig. 3, is unwound from a storage roll 27, and passes around a rotating heated drum 25 after non-plasticised continuous filament cellulose acetate yarns supplied as two "sheets" of yarns 20, 21, from warp beams have been pressed on to its outer surface by a glass-cloth-covered pressure roll 24. The yarns become bonded to the staple cellulose acetate fibres in the carded web and the laminated product leaves the drum after passing under a pressure roller 28. The laminated web is cooled by an air-jet 29, passed through a coloured impregnating composition in bath 34, over polythenecovered guide rolls 35, 36 into a drying oven 37, over guide rolls 38, over a smoothing slat 39, over guide rolls 40, 42, and 44 with intervening ironing drums 41 and 43, and is wound up at 45. The web may be slit into fancy ribbons for tying up flowers or parcels. The impregnating composition may be an aqueous, denatured ethyl alcohol solution of a copolymer of vinyl acetate and 2-ethyl butyl maleate and an alcohol-soluble dye.

Title: Rolling mill module
IPC: B22D11/12
Filed: 1973-03-13
Abstract: 1422723 Rolling mills USS ENGS & CONSULTANTS Inc 13 March 1973 [20 March 1972] 12129/73 Heading B3M A rolling mill module, which rolls a bar issuing from a continuous casting plant, includes a frame in which two closely spaced pairs of rolls are housed. The axes of the rolls of the two pairs are at right angles to each other, and the spacing between the pairs is less than the diameter of a roll plus four inches. One such module 30a, Fig. 2, rolls one of four bars 14<SP>1</SP> to 14<SP>11</SP> from the casting plant, and houses horizontal roll pairs R 1H  and R 3H  and vertical pairs R 2V  and R 4V  driven by motors 116. The roll pair B 2V , Fig. 3, is supported in a housing 42, the rolls 44 and 66 being urged towards one another by respective hydraulic cylinders 56 and 68. The cylinder 56 has a slightly greater effective area than cylinder 68. A spacer 72 between each pair chocks 52 of the rolls determines the roll spacing. Rams 84a and 84b in the chocks separate the rolls when the pressure is released in cylinder 56 and 68. This release occurs automatically if an overload pressure exists in the cylinders, due for example to cold head or tail ends of a bar passing between the rolls. Damage to the rolls is thereby avoided. Each module has lugs 40 at its end to enable it to be removed from the mill plant, and the rolls are removable from the modules. By tilting the rolls through 45 degrees in the modules, diamond section bars can be rolled. The rolls may be water, steam, or air cooled, and are of composite construction, having roll collars mounted on shafts 13 by an interference fit.

Abstract: 550,786. Regenerated cellulose filaments, films &c. TRANSPARENT PAPER, Ltd., and PELLATT, D. L. Sept. 24, 1941, No. 12382. [Class 2 (ii)] Formates, especially alkali metal formates, are used instead of glycerine for plasticizing regenerated cellulose in the form of foils, films, filaments, tubes &c. The formed structure before drying is passed through a plasticizing bath containing a substantial proportion of the salt of formic acid, e.g. the potassium or sodium salt, but not containing any substantial proportion of strong mineral acid. The bath may include glycerine or other glycerine substitutes such as glucose, sugar derivatives, urea, or alkali metal lactates. The final dried product is preferably arranged to contain 5-25 per cent. plasticizer. When used with urea as plasticizer sodium formate tends to prevent the urea from crystallizing out. Sodium formate also accelerates the rate atwhich a reel. of film can absorb moisture to acquire the correct flexibility when being unwound., Sodium formate may also be used with glycerine.

Title: Change speed mechanism
IPC: F16H63/46
Filed: 1931-04-27
Abstract: 387,311. Controlling change speed gearing. MENESSON, M., 27, Boulevard du Parc, Neuilly-sur-Seine, France. April 27, 1931, No. 12426. Convention date, May 9, 1930. Void [Published under Sect. 91 of the Acts]. [Class 80 (ii).] A gear shift for a conventional change gear 23, Fig. 3, is automatic in the sense that when a dog 32 is held by a spring 37 in engagement with a striker 28, successive depressions of an engine clutch pedal (not shown), acting through a lever 57, Fig. 5, effect change from middle speed to direct drive and back again. The dog 32 is rigid with a bolt 33, Fig. 3, slidable laterally in a slider 35 supported on a fixed guide bar 39 parallel to two gearshift guides 25, 26. A stud 40 on the slider 35 engages a forked lever 42 supported on a fixed pivot 43 and engaging at 44 with a flylever 46 supported on a fixed pivot 47. Pivoted to the fly-lever are two hooks 48, 49 pressed together by springs 66, 67 and adapted to engage alternatively over a stud 54, Fig. 5, carried by a slide bar 55 operated by the engine clutch pedal. The bar 55 carries a V-shaped latch 61 which co-operates with ramps 52, 53, Fig. 11, on the hooks 48, 49, so that on successive reciprocations of the bar 55, the stud 54 is engaged alternately by the two hooks, and the fly-lever is canted one way and then the other so that through the lever 42, slider 35, and dog 32, the fork 28 is struck alternately to the opposite ends of its travel for middle and high speeds. To engage the low speed, as in starting a vehicle, the dog 32 is first moved across to engage another fork 27, Fig. 3, by a manual pull on a cable 38 which compresses the spring 37 and allows another spring 34 to expand. Depression of the pedal then causes the stud 54 to pull the hook 48 and move the slider 35 appropriately, the latch 61 holding the other hook free. To effect reversed driving, a manual pull on a second cable 65, Fig. 5, through a bolt 63 causes a tappet 62 to tilt the latch 61 so as to change the engagement of the hooks, Fig. 11, prior to the pedal actuation.
