Title: Improvements in or relating to the manufacture of tubes and hoses from thermoplasticmaterial
IPC: B29C65/00
Filed: 1960-09-12
Abstract: 954,700. Seaming non-metallic sheet material. J. FERENCZI. Sept. 12, 1960 [Oct. 13, 1959], No. 31356/60. Heading B5K. A method of manufacturing tubes or hoses of polyethylene comprises forming a tube by the blowing method, flattening the tube so that two foils of material overlie each other, stressing the tube, and prior to winding the tube, splitting it longitudinally by moving it longitudinally past a stationary heated cutting-tool which is heated to a temperature sufficiently high above the fusion temperature of the polyethylene to cause the superimposed cut edges of the tube walls to be welded together along their length. As illustrated, a tube made of foil layers 3, 3<SP>1</SP> lying upon each other pass between guide drums 1 and 2 in the direction of arrow 10. A cutting tool 4 secured to heating head 5 heated by electric heater 5<SP>1</SP> and controlled by thermo-element 6 serves to split the foils 3, 3<SP>1</SP> and at the same time to weld the cut edges together. The angle a α of the cutting edge 7 to the plane of the foils is preferably less than 60 degrees and the cutting tool is of increased thickness beyond the cutting edge so as to prevent the cut edges coming together again.

IPC: B65H49/34
Filed: 1953-11-12
Abstract: 748,102. Unwinding. NATIONAL MACHINERY CO. Nov. 12, 1953, No. 31366/53. Class 120 (2). [Also in Group XXII] Mechanism for supporting coiled wire-stock which is to be fed, for example, by intermittently-rotated feed rolls 11, Fig. 1 (not shown), to a wire-stock handling machine, e.g. a nail or bolt making machine, comprises a rotatable support 4 adapted to receive coiled wire stock 8, 9 to be unwound by rotation of said support, a constant speed power unit, e.g. an electric motor 17, to rotate said support, a lever 15 pivotally mounted at 25 adjacent said support and extending therefrom, a stock guide 14 on said lever arm remote from the pivot point 25, a speed change device 18 through which the power unit rotates the support 4, and means operatively connecting said lever arm 15 and said speed change device 18 whereby movement of said guide 14 in response to variations in tension resulting from varying demand of wire stock varies the rotational speed of the support, The speed change device 18 is operated by an arm 23 linked at 28 to the lever 15 and arranged so that counter-clockwise movement of the lever, as tension in the wire increases, increases the speed of the output shaft of the speed change device and clockwise movement of the lever 15 as the wire slackens, allows the lever to drop, decreases the speed of the speed change output shaft and may eventually stop it. Stops 26, 27 limit the movement of the lever 15.

Title: Improvements in or relating to collecting mechanism for use in cigarette making and like machines
IPC: A24C5/32
Filed: 1937-11-15
Abstract: 504,842. Endless - belt conveyers. RUAU, F. F., and MOLINS MACHINE CO., Ltd. Nov. 15, 1937, No. 31404. [Class 78 (i)] [Also in Group VI] In collecting mechanism for continuous-rod machines in which articles severed from a workpiece are received upon an endless conveyer, spaced apart axially, and delivered laterally from the conveyer by transfer, means, an element movable in the same direction as the conveyer is moved into engagement with the leading end face of the article and, during a part of the time of engagement, and while the article is on the conveyer, is moved with the article at a slower speed than that of the conveyer so that the axial speed of the article is less than the speed of the conveyer when the article is delivered laterally. As applied to a cigarette-making machine, cigarettes cut from a continuous rod and spaced apart on a conveyer belt 4 by a rotating disc 5 are moved laterally on to a band 17 by blades 6 supported by guides fixed to carriers 7 on a rotating shaft 19. The blades are reciprocated by a stationary cam 11 against which the end faces 10 of the blades are held by springs 9, which also prevent ejection of the blades from the guides by centrifugal force. An abutment 12 on the blade engages the leading end face of a cigarette before it is moved transversely, the cam 11 moving the abutment with a continuously decreasing speed to reduce the axial speed of the cigarette before it leaves the belt 4. The cigarettes on the band 13 are straightened by thin pivoted plates or by pieces of flexible material. Specifications 423,503, 430,742 and 462,540, [all in Group VI], are referred to.

Abstract: 1,038,650. Woodworking. A. CREMONA. July 23, 1965 [April 3, 1965], No. 31534/65. Heading B5L. A horizontal wood shearing means has an arrangement for effecting automatic engagement and disengagement of a pressure bar member 3 from a cutter block member 1 comprising a hook 13 having a fulcrum 14 on one of the members engaging a crank-shaft 15 on the other member, the crank-shaft being rotatable to cause the hook to disengage the crankshaft to permit displacement of the pressure bar member from the cutter block member. The cutter block member and pressure bar member have shoulders 10, 9 reciprocatable along slideways 6 by a drive consisting of connecting rods 11, Fig. 3 (not shown), joined to flywheels on a main shaft 12, the movement of the members, which have a knife 2 and pressure bar 4, acting on a block of wood 7 fed vertically upwards on a slide 8, the wood abutting a face 5. The crankshaft 15 is located between gears 16 driven by chains 17 from pinions 18 on shafts connected by universal joints 20 to shafts 19 driven by a motor 21. Rotation of the crank-shaft 15 through 210 degrees clockwise from the position shown in Fig. 2 causes the crank-shaft to engage the hook 13 so as to pull the cutter bar member and pressure bar member together so that they reciprocate together during operation of the machine. Reverse rotation of the crank-shaft 15 through 210 degrees disconnects the members to enable an operator to sharpen the knife 2. The disengagement is effected when the cutter bar member is in its forward dead-centre position.

Abstract: 204,962. Wilkinson, C. H. Nov. 23, 1922. Ball and float valves.-A float actuating-device particularly applicable for operating the discharge valves of steam traps is provided with release catch mechanism to give a quick opening and closing of the valve. The float A is cylindrical in shape and has trunnions D' mounted towards one end of the float and adapted to turn in the ends of a forked float lever E pivoted to a fixed bracket H at I. The trunnion D<1> is also surrounded by a guide, frame L formed on a lever pivoted at F to a fixed bracket G and connected at J to a pin K on the float by a link B. While the water level is rising the float first tends to turn in a clockwise direction, causing the horizontal part of the frame L to engage the trunnion D<1> and prevent the float rising. As the water level approaches its maximum position the float rotates in a counter clockwise direction, which releases the catch and allows the float to rise. The lever E has a projection adapted to engage a second lever connected to the discharge valve for opening and has a projection on the frame L to release a pawl arranged to hold the valve in the open position and so permit the valve to close.
