Title: Improvements in or relating to the production of bags or the like with seamless bottoms
IPC: B31B3/28
Filed: 1959-11-09
Abstract: 899,726. Making bags. OTT K., [trading as HABRA-WERK., W. F. OTT]. Nov. 9; 1959 [Nov. 15, 1958], No. 37841/59. Class 94(2). Bags are made by a method which comprises folding a web of heat-sealable material into a U-shape, inserting into the fold a plurality of sets of plate members, pressing and welding together, between the plate members, the upright portions of the U to form pockets and separating the pockets to form individual bags. Baffles 3a combine with a wedge 3 to impress a U-form on the web. Plates 5, 6, suspended by arms 9 from a conveyer belt 4, enter the inside of the U-fold and are spread apart, by the operation of mechanism on the supports 9, and so cause the web to be advanced with the belt to position II, where heated radial projections 12 from a drum 13 co-operate with projections 14 from a drum 15 to weld seams 16 across the web. The projections may be resiliently mounted. At position III a pocket has been formed open only at the top. At position IV cutting means 17, 18 co-operate to separate the web into bags. A cam 25 spreads the plates 5, 6 to open the bags completely at position V. Each opened bag is swung around a roller 8, through position VI, to position VII, where spring-pressed fingers 20, 21, mounted on a drum 23, fold the bottom end flaps 19 against the bag bottom. The jaws may be in two parts, Fig. 4, and cutters may function between the two parts whereby the bags are separated as soon as they are welded. In the arrangement shown in Fig. 8 the bags are turned through an angle of 90 degrees, from A to B, and the weld seams pass between heated guide bars 110 by which they are secured to the side walls of the bag. The bottom end flaps 19 are folded in by a guide rail 105 and are heat-sealed by elements 106 carried by a drum 107. The welding jaws may be mounted on chains which move them along with the web, so giving a longer welding time. The edges of the spreading plates may converge, resulting in tapered bags. Also the spreading plates may have hinged joints whereby, when apart, they also provide a backing for the bag bottom. The web may be of plastic material, or of paper coated with thermoplastic material on one or both sides, or coated on one side with plastic and on the other with lacquer, and may carry printed matter. The movement of the belt 4 may synchronize with that of a delivery conveyer operating in the direction 26.

Title: Reversing device, preferably in screw thread cutting apparatus
IPC: B23G1/46
Filed: 1962-10-10
Abstract: 1,025,195. Screwing devices. SVENSKA PRECISIONSVERKTYG A.B. Oct. 10, 1962 [Oct. 11, 1961], No. 38342/62. Heading B3N. [Also in Division F2] A reversing device for a screw-cutting machine comprises a spindle 12 drivingly connected to a port 10 the drive from which is transmitted via spring-loaded balls 36 to a coupling element 38, and to an axially displaceable sleeve 58 via balls 70 to a driven part 46 carrying the threading means. Rotational resistances encountered at the end of the screwing operation overcome the spring forces of the coupling between balls 36 and port 38 and the balls rotate with part 10 by jumping the recesses in the subsequently stationary element 38. The tension springs 34 determines the torque transmitted by the coupling, the tension being adjusted by axial movement of the sleeve 16. At the end of the screwing operation axial pressure is relieved from the driven part whereupon the sleeve 58 is axially displaced to engage its other extreme position in which ball 78 engages a lower groove 86. A driving connection is now established between a reversing sleeve 102 and sleeve 58 by means of dogs 60 on the sleeve 58 engaging in notches 106 in the sleeve 102. The drive from the spindle now passes through part 10, ring 122, balls 128 and the lower bearing with split outer race 108, 110 via sleeve 102, sleeve 58 to the driven part 46. The ring 122 tends to have relative to the port ring 110 displacing in recesses 124 the balls 128 causing the port ring 110 to be displaced axially upward. The pressure on the balls 112 is then transmitted axially to port ring 108 and subsequently via spring washer B2 to intermediate ring 134 which increases the radial jamming between the balls 112 and rings coacting therewith. The balls 112 are retained in a cage 140 the openings therein being alternately axially displaced which improved the stability and vibrational tendency of the bearing. The cage is held stationary during operation by arm 144 attached to a projection 142 thereon so that the inner and outer races of the bearing rotate in opposite directions effecting the reversal of the driven part 46. The reversing device is applied automatically in accordance with the driving torque and the predetermined pressures of the springs actions under the conditions of operation of the device. In another embodiment the position of the port rings 108, 110 of the reversing bearing are interchanged and the ball 128 co-operates with the outer race of the inner ball bearing.

Title: Turbo brake
IPC: F16D57/06
Filed: 1962-10-19
Abstract: 963,666. Hydrodynamic brakes. C. SCHULERVOITH, M. VOITH, H. W. SCHWEPPENHAUSER, and C. KNAPP, [trading as VOITH-GETRIEBE KOMM.-GES.]. Oct. 19, 1962 [Nov. 14, 1961], No. 39726/62. Heading F2E. A hydrodynamic brake of the bladed rotortype, particularly for a rail vehicle, is regulated in such a way that above a predetermined speed the power absorption is constant, i.e. the braking torque first rises in proportion to the square of the speed and then falls hyperbolically. Regulation is effected by an outlet valve from the working chamber which is controlled in part by a spring acting in the closing direction and additionally by means exerting a force on the valve which is proportional to speed and independent of the pressure in the working chamber. In one embodiment, Fig. 2, the outlet 6 from the working chamber 5 of the hydrodynamic brake 1 is throttled by a piston 8 acted on by a spring 9 and additionally by electromagnetic force exerted by a solenoid 13 to which current 'is supplied by a generator 16 driven from the brake shaft and giving an output voltage proportional to speed. The electromagnetic force may act with or against the spring 9 according to the type of hydrodynamic brake used. In a second embodiment, Fig. 3, the brake is of the kind having a spirally formed housing 21 leading to outlet 64 to the throttling arrangement, a second outlet 35 to a sump 30 via a combined feed and return regulator piston 27 controlled manually by a lever 29 and influencing both return flow and filling of the brake by a pump 31 via pipes 33, 34, and a third outlet 24 to a cooler 25 recirculating fluid via pipe 26. The regulator comprises a stepped piston 38 having large and small diameter parts 41, 40 and a compensating piston 39 secured to a shaft 45 passing through a bore in the stepped piston and mounting adjustably an abutment 46 for a spring 47 acting on piston 38. Fluid pressure at outlet 64 acts in the region between parts 41, 40 on both pistons such that the net effect on the piston assembly is nil, but piston 38 is moved relatively to the compensating piston 39 to uncover an outlet 52a leading via pipe 52 to the sump. The additional control is effected by a piston 54 which is connected by a coupling 62, 63 to the piston assembly 38, 39 and acted on by fluid supplied by a pump 59 which is driven from the brake shaft and adapted to generate a pressure proportional to speed. This fluid pressure, modifying the operation of piston assembly 38, 39, is opposed by a spring 55 adjustable by screw 57. An adjustable stop 54a limits the stroke of piston 54. In the modification of Fig. 4, other types of hydrodynamic brake are catered for by replacing the direct-coupled piston 54 by a piston 77 which acts via a suitably-shaped cam 75 on a guide piston 71 connected via the coupling 62, 63 to the piston assembly 38, 39.
