Title: Apparatus for the welding of protruding package parts,such as transverse seams,package lappets or the like,to filled packages especially of coated paper,and devices adapted for carrying out such methods
IPC: B65B51/14
Filed: 1965-08-16
Abstract: 1,071,760. Seaming non-metallic sheet material. HOLSTEIN & KAPPERT MASCHINENFABRIK PHONIX G.m.b.H. Aug. 16, 1965 [Aug. 19, 1964], No. 34937/65. Heading B5K. [Also in Division B8] An apparatus for welding the flaps of a parallelepipedic package against the package comprises a welding head 21, movable towards the package, with air nozzles 23 which direct hot air between the flaps 25 and the package prior to the flaps being pressed into engagement with the package. The welding head 21 comprises a reciprocating plunger 22 with the hot air nozzles 23 which are movable towards and away from each other on guide rods 29. When the plunger 22 is moved downwards over the package tops, the nozzles 23 are situated remote from each other, and hot air is supplied under the flaps 25 of each package. When pivoted parts 24 fold the flaps 25 to press them on to the package, the nozzles 23 are withdrawn along the guide-rods 29 towards each other, Fig. 2 (not shown), and the plunger is retracted, Fig. 3 (not shown). Several packages can be sealed at the same time, Fig. 4 (not shown), by the separate nozzles 23, and then ejected by a pusher (20). In another modification, Figs. 5, 6 (not shown), for welding package flaps, a package holder has four chambers (35) each housing several packages. The holder is rotatable about a central shaft (33) and after the packages have been fed into the chambers by pushers (49), plungers (44), above the top of the two upper chambers, are inserted into a covering channel (40). Air is directed from common ducts (43) over electric heaters (45) in the plungers and through holes (41) under the package flaps (47). Pivoted portions (39) on the frame fold the flaps against the package and seal the package. The plungers (44) are then withdrawn and the holder is rotated through 180 degrees so that the other two chambers are uppermost. Movable walls (38) of each chamber (35) are pivoted away from the package walls which they support by operation of toggle links (42). The packages are then ejected by the pushers (49). The holder (32) may be constructed in star form, preferably with equal angles between the chambers.

Abstract: 1,262,329. Photo-copy apparatus. PITNEYBOWES Inc. July 11, 1969 [Aug.7, 1968], No.35166/69. Heading G2A. A photo-copy machine has guide means defining a single copy original sheet feed path and two original recirculating sheet guide paths of different lengths, gating means operable to cause an original to move along a selected one of the recirculating sheet guide paths, control means for the gating means for causing an original partaking of its first recirculating cycle to always move along the longer one of the two recirculating sheet guide paths, and additional control means operable in response to a sensed condition of the original for operatively conditioning at least a portion of the gating means to repeatedly direct the original along the shorter one of the recirculating sheet feed paths. An original is fed from an inclined upper deck plate 26 by rolls 30, 31 along arcuate guide-plates 55, 56, 59 and thence by rolls 31, 32 to an illumination station 12. The original is then fed to a first gating member 71 disposed near rolls 65, 66, member 71 being mounted on a shaft 86 which is pivotted to direct the original to guidemembers 67, 72 or round roll 65 guided by surface 85 and guide-member 87 which form part of the shorter recirculating sheet guide path. A second gating member 76 directs the original either out of the machine to an output station (14), Fig.1 (not shown) or round a roll 73 guided by surface 77 and guide-members 81, 82 which form part of the longer recirculating sheet guide path. Switches A, B and C have operating arms which extend into the guide paths as shown. If the leading edge of an original operates switch C before the trailing edge has run off the arm of switch A, then the operation of switch B ensures that the gating member 71 selects the longer recirculating path. If the trailing edge has already run off the arm of switch A, then gating member 71 selects the shorter recirculating path. A manually set ratchet counting wheel is moved one step for every operating of switch A and for the last copy the solenoids operating gating members 71, 76 are de-energized so that the original is directed to the output station.

Title: Vacuum cleaner assembly
IPC: A47L9/24
Filed: 1958-11-10
Abstract: 851,462. Suction cleaners. LEWYT CORPORATION. Nov. 10, 1958 [Dec. 12, 1957 ; July 23, 1958], No. 36028/58. Class 8(1). The field winding of a motor 35, Fig. 2, driving the fan 39 of a canister-type suction cleaner forms the primary winding of a stepdown transformer the secondary winding of which is connected by leads 63, 64, Fig. 5, within a suction hose 25 to a motor 105, Fig. 12, located within a suction nozzle at that end of the hose 25 remote from the cleaner casing 20 and serving to drive a rotating brush 122. The leads 63, 64 are also connected to a lamp 106 mounted behind a translucent window at the front of the nozzle. Suction air normally passes from the nozzle inlet 112 beneath the brush 122 into a space bounded by walls 113, 114, 115 and 116 to an outlet 117 to which the hose 25 is connected but in the event of said inlet 112 being substantially completely obstructed air is drawn through a suction regulating valve 120 of the diaphragm type set in wall 115. The lead 63 is insulated whilst lead 64 is bare and each forms a helix as shown in Fig. 3a within the hose 25. The casing end of lead 63 is wound round a ferrule 65 and is connected through a disc 66 to a resilient conductor strip 53 running along but insulated from a metal tube 24 and having a spring contact 54 which when the tube 24 is inserted in the casing inlet 22 makes electrical contact with a shell 49 connected to one of the secondary leads 46 ; the other secondary lead being connected to the cleaner casing at 47 and hence to the tube 24 and the bare lead 64. The other end of the hose 25 is connected by a hand grip 26 to a metal sleeve 71 which telescopes into a wand 27 which in turn telescopes into a flared tube 86, Fig. 9. The latter is connected by a hose 91 to the nozzle outlet 117 and by a yoke 90 to the nozzle casing 98 ; the yoke having pins 99 by which it is pivoted to said casing 98. Specifications 760,275 and 881,463 are referred to.

Title: Improvements in and relating to hydraulic master cylinders
IPC: F15B7/08
Filed: 1965-08-23
Abstract: 1,102,929. Hydraulic brakes. H. A. L. VENNER (Renak-Werke VEB). 23 Aug., 1965, No. 36094/65. Heading F2F. In a dual circuit master cylinder for hydraulic braking systems, a primary piston 3 and a secondary piston 2 are arranged one behind the other, a connecting rod 28 and a compression spring 27 being arranged between the primary and secondary pistons, the connecting rod being displaced by a spring 32 in the direction of the primary piston and being arrested axially in the same direction in the secondary piston by means of a pin member 29 which engages a disc 30 and a spring ring provided in the rearmost end of the secondary piston 2 so that a resilient seal 31 on the end of the connecting rod 28 facing the primary piston 3 opens, in the position of rest, an equalizing bore 33 for communication with an equalizing chamber C communicating with a replenishment reservoir via a bore 35. The secondary piston 2 is also provided with an equalizing bore 19 for communication with an equalizing chamber D communicated with a replenishment reservoir via bore 20. The equalizing bore 19 in the secondary piston is adapted to be closed by means of a valve 15, 16 in any position of the secondary piston other than the position of rest. In operation, when the primary piston 3 is moved by a pressure rod (not shown) connected to the brake pedal, the sealing face of the piston 3 approaches the resilient seal 31 on the connecting rod 28 and the chamber A is closed from communication with chamber C. At the same time the secondary piston 2 is moved by the compression springs 27 and 32 and also by the slight pressure building up in the chamber A to close the bore 19 by the packing 16 of the valve 15 so that a further rise in pressure proceeds uniformly in both the pressure chambers A and B leading to respective braking circuits connected to closure screws 7 and 43. When the braking action is terminated the compression springs 4 and 11 and 27 and 32 press the pistons 2 and 3 back into their initial positions, the push-rod 14 and connecting-rod 28 reaching the position of rest sooner than the two pistons due to stop members being provided on the push-rod 14 and the connecting-rod 28 to effect an opening of the equalizing bores 19 and 33 to allow communication between equalizing chamber C and the primary pressure chamber A and between equalizing chamber D and the secondary pressure chamber B. Valve members 41 and 8 ensure a degree of pre-pressure in each of the braking circuits.

Title: Improvements relating to variable speed power transmission mechanism
IPC: F16H15/38
Filed: 1933-12-28
Abstract: 431,199. Variable speed gearing. CLOUDSLEY, J. L., 5, Chancery Lane, London. Dec. 28, 1933, No. 36477. [Class 80 (ii)] In variable-speed gearing of the kind comprising coaxial driving and driven toric discs and intermediate rockable rollers, unwanted stresses are eliminated by mounting one or more of the toric discs on a central shaft by means allowing the disc to rock to a limited extent and to slide along the shaft. Fig. 4 shows a twin-set arrangement like that shown in Fig. 10 of Specification 392,589, the drive passing from front and rear end discs 1, 9 to a middle double disc 12 through front and rear roller sets 11, 10. In Fig. 1, a rear end disc 9 is shown supported on a part-spherical sleeve 16 the latter being fast on the central shaft 3 of the gearing. There is a dog connection 18 between the disc 9 and the sleeve 16 which allows the former to rock as it is constrained to do when the rollers are not all of equal diameter. The disc 9 is pressed right by Belleville washers 21 and is free to slide to apply tractive friction to the rollers. A form is described with a double dog member between sleeve and disc and connecting them. Fig. 3 shows a front end disc 1 free to slide and rock on a similar part-spherical sleeve 29. Power passes to the disc 1 from a driving cup 22 through a dog connection 23, through a torque cam ring 24, and through thrust multiplying balls 25. The torque ring 24 is allowed to rock along with the disc 1 by a spherical support 30 for a race 31 of a bearing 32 which supports the said ring. Part of the power passes to the rollers 11 and part through a coupling sleeve 27 to the sleeve 29 and on through the shaft 3 and disc 9 to the rollers 10. In the arrangement of Fig. 4, the rocking of the disc 1 is rendered possible by mounting it with a loose cylindrical bearing fit at 40 on the shaft 3 and providing an oil duct by which a liberal supply of oil is directed into the intervening space upon which oil the disc is floatingly supported. Specification 405,453 also is referred to.

Filed: 1964-09-08
Abstract: 1,095,657. Hydro-pneumatic shock absorbers. GIRLING Ltd. Aug. 27, 1965 [Sept. 8, 1964], No. 36682/64. Addition to 1,092,341. Heading F2S. An hydraulic damper of the kind in which axial movement of a piston 12 in a cylinder 10 containing hydraulic fluid is controlled by the passage of fluid through valves or restricted orifices which may be located in the piston or in the cylinder is characterized in that a bleed passage, by-passing the piston, is controlled by a mass responsive to inertia forces and having a predetermined frequency response. The mass 25, slidable on a piston rod 14, is supported by a spring 27 so that, in its normal position, the outlet port 24 of an axial passage 23 through the piston rod 14 leads into a restricted annular passage 33 between the slightly enlarged bore of the mass 25 and the piston rod 14. Annular grooves 28, 29, formed in the mass at the upper and lower ends of the passage 33, each communicate with a radial passage or passages 31, 32 leading to the outer surface of the mass 25. Flow of liquid in both directions through ports 19 in the piston 12 is controlled by a resilient annular plate valve 20 which cooperates with concentric seatings 21, 22, a floating piston 18 separating an upper gas pressure chamber from the hydraulic liquid in the remainder of the cylinder. The mass 25 and spring 27 are designed to have a natural frequency which is the frequency of wheel bounce so that under cyclic condition associated with wheel bounce the mass will move far enough to close the port 24 and provide high damping. For random impulses on the wheel movement of the mass 25 in either direction causes the length of the passage 33 through which fluid flows between the part 24 and one of the grooves 28, 29 to be progressively reduced until the groove 28 or 29 comes into alignment with the port 24 when flow is substantially free. Further movement of the mass closes the respective groove 28 or 29.

Abstract: 786,280. Reciprocating pumps. SATZGER, E. Dec. 20, 1954 [Feb. 18, 1954], No. 36711/54. Class 102(1). Test apparatus for testing the delivery quantity and point of delivery of a fuel injection pump 1 comprises a pump 2 having separate piston areas arranged to supply a low pressure for feeding the injection pump 1 and a high pressure capable of by-passing the injection pump delivery valve, with approximately the same driving power. The pump 2 feeds the pump 1 through a strainer 28. Liquid may be by-passed through a relief valve 8 when a valve 9 is open and a valve 27 closed or through the valve 27 when open and the valve 9 closed. When both valves 9, 27 are closed the pump 2 automatically builds up high pressure controlled by a by-pass valve 23 or an air buffer cylinder 25. The pump 2 comprises a piston 36, Fig. 3, engaged by a plunger 34 actuated by a cam 32 and returned by a spring 37. With low back pressure the piston 36 draws liquid through a valve 41, delivers it through a valve 42 to the upper side 39 of the piston and then delivers it to the line 5 through a valve 40. When the valves 9, 27 are closed a high back pressure is created and the spring 37 cannot return the piston 36 and thereafter pressure is built up by the plunger 34 alone.
