IPC: D01G1/04
Filed: 1971-08-02
Abstract: 1345425 Cutting tow LUMMUS INDUSTRIES INC 2 Aug 1971 [8 Feb 1971] 36293/71 Heading D1F Apparatus for cutting tow or like material comprises a cutter-bearing drum, a pressure roller for pressing the material into cutting engagement with the cutters, and sensing means for sensing the cutting pressure. As shown, Fig. 1, a pressure-roller 11 pressing material 12 onto cutters 13 of rotating drum 10. Roller 11 is rotatably mounted on arm 21 pivoted on fixed pin 23. Arm 24, rigid with arm 21, has pins 38 pivotably supporting a member which slidably receives stud 34. Handle 51 and member 26 are pivoted on fixed pin 27. Member 26 has pins 32 pivotally supporting member 31 which supports stud 34. Roller 11 is pressed onto material 12 by spring 41, an adjustable stop on arm 24 coacting with stop 42 to position roller 11. Stud 34, member 26 and pins 38, 32, 27 form a toggle clamp holding roller 11 in position. If the pressure on roller 11 rises sufficiently, e.g. due to increased thickness of material 12; arm 24 is pivoted against spring 41 to open notch 46 and stop drumrotating motor 53. Rotation of handle 51 about pin 27 withdraws roller 11 from drum 10. Alternatively, Fig. 6, pressure roller 11 is pivotally mounted on member 64 slidable between guides 66. Roller 11 is pressed against material 12 by spring 79 via link 71 and member 64. Increased pressure on roller 11 causes the roller to slide from drum 10, against spring 79, and thereby open notch 83 to stop drumrotating motor 53. Link 71, stud 74 and pivot pins 69 72, 77 form a togglemechanism holding roller 11 in position; Roller 11 may be withdrawn from drum 10 by rotation of handle 89 about pin 77. The cutting pressure may be monitored by strain gauge positioned on the apparatus.

Filed: 1966-08-16
Abstract: 1,191,264. Boot-making machines. BRITISH UNITED SHOE MACHINERY CO. Ltd. 15 Aug., 1967 [16 Aug., 1966], No. 36519/66. Addition to 931,796. Heading A3B. The machine for simultaneously moulding and out-flanging the heel end portion of a shoe upper of Specification 931,796 is modified in that the inner mould in two parts which are moved apart to tension the upper and means for clamping the upper against the inner mould are replaced by a one-piece mould mounted on a support and grippers mounted on each side of the support for gripping side portions of the upper, the mould being movable lengthwise of the upper relative to the support and the grippers to tension the end portion of the upper. As shown an inner form 500 is slidable on a sleeve 504 through which a heating element 501 passes into the mould. The sleeve 504 is supported by a bracket 506 forming part of structure 510 which is pivoted at 512 to the head casting 1, to allow access to flange-forming members 71 and to facilitate exchanging the inner form for one of a different size, but is normally held in place by springs (522) Fig. 1 (not shown) secured to the base casting 3. A pair of pneumatically-operated grippers 520 are on opposite sides of the bracket 506. In operation, an operator depresses a pedal which opens the gripper jaws; when the pedal is released the jaws close on the upper and move in a toeward direction relative to the mould 500 to take up any slack in the upper. A pneumatic circuit is then actuated to move outer moulding member 9 towards the mould 500 and swing the flange-forming members 71 apart beneath the outer moulding members 9 and then upwardly against them as in Specification 931,796. Air is then supplied to a piston and cylinder arrangement 516 causing plunger 518 to contact an extension 508 of the rod 501. The rod slides heelwards within the sleeve drawing the form along the outer surface of the sleeve, whilst the grippers remain stationary so that the heel end portion of the upper is tensioned and moulded on the form.

Title: Improvements in or relating to motor road repair or tower wagons
IPC: B60M1/28
Filed: 1934-12-28
Abstract: 449,754. Portable platform elevators. WOODHEAD, R., and WOOD HYDRAULIC HOIST CO., Ltd., 30A, Union Street, Southport, Lancashire. Dec. 28, 1934, No. 37118. [Class 78 (iii)] [See also Group X] The type of apparatus in which a hydraulically-extended telescopic tower mounted on a wheeled vehicle and carrying a slueing platform at its upper end is modified by providing (1) means operable from the platform for slueing the latter and fixing it in any desired angular position, (2) a pump with distributing valves operated from the platform for manipulating the tower, (3) means for connecting adjacent sections of the tower in a watertight manner, and for cushioning the movement of the telescoping parts at the limit of extension. Fig. 1 shows the wheeled vehicle 1 carrying the telescopic standard 3, 4, 5 and the upper platform 6. A pump of the gear wheel type, driven by the motor on the vehicle, draws liquid through a pipe 11, Fig. 4, from a tank and delivers it past the non-return valve 12 and hand-controlled plug valve 13 to the delivery pipe 7a leading to the telescopic tubes. A screw-adjusted ball-valve 24 returns excess liquid to the supply tank through the pipe 25 at a set predetermined pressure. The valve 13 can be set to three positions as follows (1) as illustrated, for extending tower, with ports 14 and 15 in communication and 16 closed, (2) maintaining the tower in an elevated position with port 15 closed and 14 and 16 forming a direct communication between opposite sides of the pump, (3) for lowering the tower, with port 14 closed and 15 and 16 in communication. The valve is operated by a crank arm 22, Fig. 5, connected by a link 22 to a system of telescoping rods and tubes 17, 19, terminating at the upper end in a socket 23 below the platform. A ring of holes on the rotating platform permits the insertion of a turning key into the socket 23 in any angular position of the platform, thus operating the valve from the platform. To rotate the platform 6, 44 a spring-controlled pawl 49, Fig. 2, is withdrawn from a notch 48 in the standard by depressing the member 52 with the foot. The hand wheel 56, Fig. 1, can then be operated to rotate the platform by toothod gearing 58, 59, the sleeve or cap 45, Fig. 2, moving angularly round the top of the tube 5 during the process. The piston 28, Fig. 6, at the bottom of each section is bolted, and preferably also keyed, to a member 30 welded into the end of the tube. It is prevented from turning by guide-bars 33 screwed to the walls of the casing 3. Fig. 8 shows spring plungers 42 which engage the upper side of the piston at the bottom of tube 4 and cushion further movement when the tubes are nearing maximum extension. The member 36, carrying the plungers, is positioned by a spacing ring 39 and screwdown ring 40, which also forms the base of a packing gland 41 tightened by the screwdown collar 3<a>.

IPC: H05B6/02
Filed: 1955-12-28
Abstract: 804,716. Heating by induction. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 17, 1957 [Dec. 28, 1955], No. 37124/55. Class 39(3) In induction heating apparatus having separable jaws between which a workpiece to be heated is introduced and to which the heating current is supplied, the jaws are hingedly connected and at least one of them is operable through the intermediary of a toggle to, or adjacent to, the common. pivot of which an operating force is applied, the closing pressure between the jaws being produced by means of a spring the line of action of which is substantially in alignment with the links of the toggle in their extended position. Each inductor jaw 2, 2<SP>1</SP> is connected to a toggle consisting of links 4, 5 having a common pivot 6. The remote ends of the links are connected at 7 to the jaw and at 8 to a sliding member 9 against which is exerted the force of a spring 10 which provides the pressure between the jaws when closed. As shown, the line of action of the spring is substantially in alignment with the links 4, 5 When the jaw is engaged with a workpiece 20 but the links are prevented from moving beyond the "in-line" position by an adjustable abutment 13. A solenoid armature 15 of which only the end 15<SP>1</SP> is of magnetic material is connected to the link 5 by an intermediate link 16, and a spring 17 also connected, to the armature causes the jaw to be disengaged from the workpiece and the links to be drawn out of alignment when the solenoid is not energized. The jaws are pivoted at 3, 3<SP>1</SP> and are connected via insulated hinges and strips 22 to the secondary winding of a heating transformer 21. Simultaneous energization of the solenoids causes the jaws to be brought into firm contact at their outer ends and the secondary circuit of the transformer to be closed. The operating force may be applied manually or by means of a fluidoperated device or an electric motor. Alternatively, the force may be applied by a spring operated in conjunction with the manual or other means.

Filed: 1950-06-23
Abstract: 786.027. Typewriters. DIRKS, G. June 23. 1950 [Oct. 1, 1948], No. 37206/54. Divided out of 786,021 [Group XIX]. Class 100(4) A printing arrangement comprises an assembly of side-by-side printing levers each having a printing surface near one end, means imparting a reciprocating movement to an intermediate part of each lever, and means restraining the ends of the levers selectively from movement so that a printing operation is performed or not according to which end of a lever is restrained. A bar 14 passes through and imparts up and down movement to an assembly of printing levers 13, only one of which is shown. The right hand end of the lever is normally held by a permanent magnet 17 which is stronger than a second permanent magnet 21, and as the bar 14 moves downwardly a printing action is performed by a nipple 20 acting through dry ink ribbon (not shown). The characters are built up from patterns of dots made line-by-line by nipples 20. If, when a bar 14 is in the uppermost position, a pulse is supplied to a winding 19 on the leg of the magnet 17 with which the lever 13 is engaged, the electromagnetism being arranged to oppose the permanent magnetism in the leg, then the right hand end of the lever is released and the opposite end is retained by the magnet 21 during the following downward movement of the lever so that no printing action occurs. These inhibiting pulses may be supplied from a CRT distributer at the output of an electronic computer. Alternatively the pulses may be arranged to initiate printing instead of inhibiting it. Between printing actions, the paper is fed step-by-step under a side-byside arrangement of levers 13 sufficient to produce one or a complete row of characters simultaneously. The bar 14 may be actuated by electromagnetic or cam means. Springs may be used instead of the permanent magnets 17 and 21 and mechanical control may be substituted for the electromagnetic selection of the printing levers. Specification 786,041 [Group XIX] also, is referred to.

Title: Purification of sodium carbonate
IPC: C01D7/24
Filed: 1957-12-06
Abstract: <PICT:0882694/III/1> Sodium carbonate is purified by cooling a slurry of unhydrated solid sodium carbonate from a temperature above 112 DEG C. to below 112 DEG  C. but not less than 32 DEG  C. thereby forming an aqueous slurry of solid sodium carbonate monohydrate which is separated to produce a pure product.  The initial slurry of unhydrated sodium carbonate is preferably prepared by forming a slurry of sodium carbonate monohydrate, heating to above 112 DEG  C. and generally from 115-150 DEG  C. to convert the monohydrate to the unhydrated salt and thereafter cooling to below 112 DEG  C. as above. In order to prevent coalescence it is preferable to keep the solids content of the slurry below 75% by weight during cooling.  As shown in the Figure, crude soda ash was slurried in water and treated in tank 10 with elemental chlorine to improve the colour and then pumped to a reactor 18 where the slurry is heated above the transition point from the monohydrate to the unhydrated salt (112 DEG  C.) and preferably at 120 DEG  C. for about five minutes.  The slurry of anhydrous sodium carbonate thereby formed is withdrawn at intervals through a retention tank when the temperature is maintained at 70-100 DEG  C. thereby converting the solid anhydrous sodium carbonate to the desired monohydrate form.  Water is added to maintain the solids concentration below 75% by weight and the slurry is preferably maintained in the tank until over 60% by weight of the monohydrate crystals have a size over 30 mesh.  The monohydrate is separated in a centrifuge 30 and the solids passed through a dryer at 150 DEG  C. where anhydrous sodium carbonate is formed.  The mother liquor is recycled.
