Title: Improvements in or relating to a carton sealing machine
IPC: B65B51/18
Filed: 1956-08-09
Abstract: 823,972. Sealing cartons by pressure. EMHART MANUFACTURING CO. Aug. 9, 1956 [Sept. 28, 1955], No. 24464/56. Class 94(1). In a machine for sealing already glued upper surfaces of a succession of cartons 12, 13 of varying heights, a slack upper belt 28, carrying rollers 31 lies on each carton and moves with it to provide the necessary pressure. A lower endless belt 10 forms a horizontal conveyer to carry the cartons 12, 13 from right to left in Fig. 1. The cartons may vary in height to a greater extent than illustrated and be in any order, The upper pressure belt 28 comprises a pair of laterally spaced endless chains 29 running on rails 37 in grooves formed by flanges 37a, 38, on side members 36 of an upper support 32. They are connected by closely spaced transverse shafts 30, carrying the freely rotatable rollers 31, which are preferably covered by an endless band 33 of cotton or other suitable material for direct contact with the upper ends of the cartons 12, 13. The belt 28 can be adjusted vertically by raising or lowering the support 32 by means of the screw devices 41 illustrated more fully in Fig. 2 (not shown), which are linked together to retain the support 32 in a horizontal position. The belt 28 is driven by a reverse gearing 55, 56, through a drive 58, known per se, which connect the sections 58a, 58b so as to maintain the speed of the upper belt about 50% greater than that of the lower belt 10. Forwardly inclined arms 53c support the belt to a level below the level of the top of the shortest carton to be passed through the machine. In this way each carton contacts a downwardly and forwardly inclined portion of the loosely hanging lower stretch of belt 28, which then lies on it as illustrated in Fig. 1, and moves with the carton because of the 50% increase in speed of the upper belt. Guides 60 may be used to prevent the band 33 from slipping sideways. The weight of the rollers may be increased if desired by inserting metal shot in them or by any other suitable means. The bottom flaps of the cartons if not already sealed, can also be sealed during progress between the belts 10, 28.

Title: Superconductor apparatus
IPC: H01F6/02
Filed: 1962-06-26
Abstract: 983,528. Superconductors; electric coils; induction coils. UNITED STATES ATOMIC ENERGY COMMISSION. June 26, 1962 [Sept. 18, 1961], No. 24474/62. Headings H1K, H1P and H1T. [Also in Division H2] In order to protect a superconductor coil producing a high intensity magnetic field from damage when it " goes normal " a second non-superconducting coil is wound within it and is connected to an external load for dissipating the stored energy. The two coils are wound in the space between two coaxial heat insulating tubes 84, which may be the walls of a dewar, and themselves form a closed torus (Fig. 1, not shown) the superconductor winding 23 is housed in slots 44 in inwardly extending tapering portions of yoke 35, of magnetic material, and this produces a high intensity magnetic field along the axis 25. The angle of taper and dimensions of the slots being chosen so that the lines of magnetic flux adjacent the superconductor are parallel to its surface to minimize the risk of it " going normal " due to the effect of the magnetic field and thus a magnetic field may be obtained at axis 25 which is higher than the critical field of the superconductor used. Lying between the superconductor coil and the inner wall 84 is a " normal " coil which has high specific heat and electrical conductivity and links with the magnetic field of the superconductor coil: this coil is connected to an external load. The second coil may be wound from hollow conductors which carry the liquid helium used for cooling the superconductor coil to superconducting temperatures, and also serves to cool the second coil when it carries current. The superconductor coil 23 is wound helically around the torus, alternately down and up the tapered slotted portions of the yoke until all the slots are included when points PP1 are connected to power source 50. In a modification the superconducting coil is housed as a single layer in the centre of the tapered portions of the yoke and is secured by a resin binder, Fig. 12 (not shown). In operation the superconductor coil 23 ends are short-circuited by contact B and it carries a continuously circulating current producing a magnetic field, if it now " goes normal " or contacts B are opened, the high intensity magnetic field collapses and induces by transformer action a current in the normal coil 61, which current is dissipated in a load 71, which may be a further electromagnet used to produce a transient high intensity magnetic field. The superconductor coil may be made from an alloy of Nb 3 Sn or Nb 3 Zr or an alloy of caesium, gadolinium and ruthenium. The " normal " coil is made from copper, or possibly gold or silver, and both coils are insulated by coating with aluminium oxide.

The guideway 10 is formed on a frame 1 and the guideway 12, Fig. 4, having tabs 13, 14, and 17, 18 formed thereon is releasably fastened to the frame 1, having respective grooves 15, Fig. 1, and 16, Fig. 5, and to a base 6, Fig. 1, having respective grooves (not shown). The pistol is provided with a barrel 2, a trigger 36, a sighting device 7, side-plates 8, a magazine 9, a firing pin 37, carried by the breech block 4, and a hammer 35. Firing is effected by pulling the trigger 36 thus causing the hammer 35 to hit the firing pin 37. The recoil of the breech block 4 cocks the hammer 35 and the return of the breech block by a spring (not shown) feeds a cartridge from the magazine 9 into the cartridge chamber of the barrel 2. In another embodiment a breech block 23, Fig. 8, is provided with a guideway 22 having a base 24 which is secured to a frame 26 and a plate 25 which, having journals 28, 28, Figs. 10 and 11, is secured to the base 24, having jaws 29. One of the latter has a groove 30 which is engaged by the plate 25, a blind hole 32 in the plate 25 having a spring 31 and a plunger 33 therein which retain the plate 25 in engagement with the groove 30 and allow the breech block 23 to pass through aperture 27, Fig. 13, of the guideway 22. To prevent firing, the left-hand journal 28, Figs. 10 and 11, is depressed thus moving the plate 25 from the groove 30 and allowing the plate 25 to pivot from the position shown in Fig. 8 to that shown in Fig. 15. This prevents the hammer 35 from contacting the firing pin 37 and interrupts the aiming line between a foresight 39, Fig. 8, and a backsight 38, Fig. 13. The plate 25 is rotated to allow firing to be effected and returns into engagement with the groove 30 of the respective jaw 29. The hammer 35 is cocked by pulling the breechblock 23 rearwardly.

Abstract: 1466098 Tunnelling machines STELMO Ltd 20 Aug 1975 [4 June 1974] 24736/74 Heading E1F Movement of a rotary cutter head-carrying boom 20 of a tunnelling apparatus in two transverse planes is controlled by an operating handle 29 mounted for universal movement in a support structure 28 to act on means operable by the pivotal movement of the handle, or by a component of such movement, in each of two transverse directions so that pivotal movement of the handle produces a corresponding positional movement of the boom. Preferably the handle is of a joy stick type and is associated with means for limiting pivotal movement of the handle so as to define the required shape of the periphery of a tunnel to be cut out by the cutter head. Such a means may be a member having a cam aperture through which the handle extends. A series of such interchangeable members, each having a differently profiled cam aperture, may be provided. Variation in size of a given tunnel section being cut by the cutter head may be obtained by making the size of an aperture in a member adjustable or by mounting the member so that the position of the aperture is adjustable in the longitudinal direction of the handle. The means on which the handle acts preferably comprises means for providing a desired value signal movement derived from movement of the operating handle in each of said two directions, means responsive to the actual positions of the boom in each of said planes to provide an actual value signal, and actuating means, e.g. hydraulic rams 24, 26, for moving the boom in each of said planes in response to error signals between the desired value signals and the actual value signals, which are preferably derived from potentiometers. Specification 1450560 is referred to.

Title: Process for the consolidation of loose soil formations by injecting gelling substances in one operation
Inventor: CARON CLAUDE
IPC: C09K17/46
Filed: 1958-08-01
Abstract: Sandy, loose, or pulverulent soils are consolidated by injecting a mixture of an aqueous solution of an alkali metal silicate and a liquid organic substance to gelatinize the silicate, which organic substance is an acid or releases an acid on hydrolysis, and has a solubility such that the mixture forms two phases, and a reactivity such that the reaction time for complete gelatinization is sufficiently long to prevent interference in the injection operation. The mixture may be an emulsion, and a surface active agent may be added.  Gelatinizing agents may be fatty acids, halogen-substituted organic acids, phenols, esters, or nitriles, and a mixture of agents of different reaction times may be used.  An exemplified mixture is sodium silicate solution, ethyl acetate, and "Teepol" (Registered Trade Mark).  The setting time may be modified by adding other esters, e.g. ethyl formate.
