Inventor: HANSEN GERHARD
IPC: B29C33/00
Filed: 1970-05-06
Abstract: 1286706 Blow-moulding and filling G HANSEN 6 May 1970 [7 May 1969] 21718/70 Heading B5A Blow-moulding and filling apparatus comprises two lower mould halves 12, 12a, to form the body and base of the article, two upper mould halves 16, 16a to form the head of the article, and a support member 28 which grips surplus at the base of the article and is vertically movable to lower the article to a support-plate 31 after opening of the upper mould halves. A tube, e.g. of polyethylene, is extruded from head 4 of extruder 5 between the open mould halves where it is held by suction by holders 14, 14a and severed by knife 8. The mould assembly is then moved along table 1 by cylinder 3 to below mandrel nozzle 6, which is lowered into the top of closed lower mould halves 12, 12a to inflate and fill the article 24. Upper mould halves 16, 16a are then closed to mould the head of the article. Support member 28 engages the tailflash 26 of the article and is lowered by cylinder 30, after opening of upper mould halves 16, 16a, to place the article 24 on the support plate 31, where tail-flash 26 is stripped. Support plate 31 is then tilted by cylinder 35 to deposit the filled article 24 on belt conveyer 36. The filling material acts to cool the article 24.

Abstract: 763,747. Automatic circuit-breakers. I-T-E CIRCUIT BREAKER CO. July 26, 1954 [Aug. 18, 1953], No. 21769/54. Class 38(5) A loose-handle circuit-breaker has its movable contact-arm 21 operated by a toggle comprising an insulating link 25 and bell-rank lever 27 which pass through a protective screen 30, the lever 27 being pivoted. on a fixed shaft 29 and biased clockwise by a spring (not shown). Pivoted at 33 to the arm 31 of lever 27 is a link 32 carrying at its other end a roller 33 and pin 35 to which is pivoted a floating link 34 pivoted at 37<SP>1</SP> to a lever 36. The latter is biased clockwise by a spring (not shown) about a fixed pivot 37 and carries a roller 40 which co-operates with a pivoted trip latch 42. To close from the position shown, either a handle 59 pivoted at 60 and bearing on a roller 55 on one end of a closing rod 51, 53, 39, or the core 51<SP>1</SP> of an electromagnet 50 at the other end, is operated, whereby a face of the part 53 of the rod pushes the roller 35 and, as the latch 42 holds lever 36 and pivot 37<SP>1</SP> fixed, rotates bell-crank 27 until the toggle 25, 27 is nearly set, whereupon the roller 33 latches on the end of a lever 44 pivoted at 45 and having a surface 46 resting on the rod 39. If the contacts close on to a fault, or if a fault occurs when the breaker is closed/the latch 42 fires the lever 36, which rotates counter-clockwise and allows roller 33 to slide down and under the end of part 53, or of lever 44, as the case may be, so that the toggle 25, 27 collapses and opens the contacts, in which conditions the spring acting on lever 36 restores the tripping mechanism to the position shown.

Filed: 1952-08-29
Abstract: 721,399. Pistons; cylinders. WALESSTRIPPIT CORPORATION. Aug. 29, 1952, No. 21799/52. Class 122 (1). [Also in Group XXXII] A piston 22 in a liquid spring device operates in a cylinder 23, Fig. 2, communicating with a chamber 21 for compressible liquid, the cylinder being compressible in response to pressure of the liquid to reduce the clearance between it and the piston. The piston 22 has a piston head 22a which carries a conventional ring seal 25 intended to function at low liquid pressures. When the piston is projected further into the casing 21, the walls of the cylinder 23 are sprung into metal-to-metal contact with the piston head 22a by the effect of the liquid pressure developed. The piston and cylinder may be made of different metals. The piston head 22a may be dispensed with, Fig. 8; the ring seal is then formed in the piston rod. Back-up ring-seals may be provided. In Fig. 8 the distortion of the cylinder wall is confined to an annular zone 128. This may be located at the inner end of the cylinder, Fig. 11 (not shown).

Abstract: 1336235 Cylinder lock mechanism E KELLER-VOLPER 19 April 1971 [13 Feb 1970] 21903/71 Heading E2A A cylinder lock mechanism for use with a door bolt mechanism has two cylinder plugs 7, 8 which are arranged in a common housing so that in use the plugs can be operated from opposite faces of the door, rotation of either plug by means of a key operating a common follower 6, the mechanism including an entrainment disc 11 which is disposed in a slot 6b in a cylindrical portion on the follower the insertion of the key into either of the plugs moving a pair of coupling members 9a, 9b so that the entrainment disc is coupled only to the cylinder in which the key is disposed rotation of the cylinder by the key through 360‹ rotating the follower, the connection of the entrainment disc to the follower being such however that the follower only rotates through a smaller angle. In the construction shown the angle through which the follower rotates is approximately 270‹ being limited to this by the engagement of a lug 6a of the follower with a portion 3 of the housing. The lug 6a is in use engaged with the bolt of the bolt mechanism. The entrainment disc has the shape of a circular segment having a chordal surface 11a which cooperates with either of two faces 14, 15 of the follower which are arranged at approximately 90‹ to each other. The follower and the entrainment disc are disposed in a recess 5 in the housing with the cylindrical portion of the follower in engagement with the end portions of the plugs and with the entrainment disc disposed between the plugs; the construction is stated to allow the housing to be stronger than it would be if the follower could rotate through 360‹ by permitting the portion of the housing underneath the recess 5 to be of greater depth; the portion 3 of the housing has a threaded transverse bore 4 for receiving a screw by which the mechanism is connected to the bolt mechanism.

A container for keeping different materials, separate before use, either in liquid or powder form, has at least two compartments with flexible walls and is of a synthetic plastics material, e.g. polyethylene or a plasticised vinyl resin. The contents of the two compartments 10, 12, Fig. 2, may be squeezed or poured out for mixing immediately before use. In a modification, Fig. 4, the contents of compartments 30, 32 and 34 may either be poured out separately from the container, or the contents of one or both of compartments 30, 32 may be mixed with the contents of compartment 34 within the container before they are dispensed. Each of conduits 42, 46 has a valve moulded integrally with a cap member, the valves having upper and lower openings which may be aligned with upper and lower apertures respectively in each of the conduits 42, 46. Rotation of cap member 56 through 90 degrees aligns an opening, leading to an upper hollow part of the valve, with a corresponding opening into the compartment 30; rotation of member 56 through a further 90 degrees brings a lower opening in the valve opposite a corresponding opening in the compartment 30 thereby allowing the contents thereof to flow into the compartment 34. The valve in the conduit 46 operates in the same way in relation to the compartment 32. The compartments may be of circular, rectangular or other polygonal cross-section.

[Also in Group XI] A container such as a refilling cartridge of plastic for a gas-fuelled cigarette lighter is filled with the liquefied gas fuel such as butane, by inserting into a filling hole in the base 15 of the container one end part 22 of a plug 20 which part 22 is shaped in cross-section such as triangular as shown or circular with indentations, to form with the edge of the hole, one or more spaces for the passage of the fuel under pressure into the cartridge, the plug being pushed home to seal up the hole before the pressure driving the fuel into the cartridge is removed. To this end the cartridge is placed in a charging machine in which the base 15 is gripped and when the cartridge is full, a plunger in the machine drives the preferably slightly tapered plug fully home in the hole. After removal of the cartridge from the machine the protruding end of the plug is cut flush with the base 15 and the flush surfaces painted over with cement.
