Title: A method of and means for clamping shoes and like footwear in bootmakers' machines
IPC: A43D111/00
Filed: 1946-07-29
Abstract: 615,588. Clamping shoes in footwear-making machines. BATA, NARODNI PODNIK. July 29, 1946, No. 22495. Convention date, March 23, 1943. [Classes 17 (i) and 112] Shoes or the like footwear, such as those of which the edges and perimeters of soles are to be polished or otherwise treated, are clamped individually, alternatively right and left, in a carrier which is moved relatively to a tool in plane rotational and translational movements in such manner that the position of say a right shoe is a mirror reflection of the position of the corresponding left shoe and two different sets of cam discs for producing the requisite relative movement between shoe and tool for shoes of opposite feet is unnecessary. In the form shown, a shoe, shown in full lines, is clamped in position in a carrier by resilient pads 15, 16, 17, 18 with resiliently mounted pivoted adjustable stops 1, 2, the former of which engages the upper edge, and the other the tread face, of the sole. The pads are carried by pistons 19, 20, 21 actuated by pressure fluid supplied to a branch pipe 33 of the pipe 31. For a shoe of opposite foot (shown dotted), the stop member 2 is engaged with the point of the toe of the upper and the member 1 with the face of the sole. The shoe carrier can thus perform the same working movements for the treatment of shoes of both right and left feet, of rotation about the axis of the clamping head or chuck 37 in a journal 38 and of translation of the slide 36, which is movable in the head to which the clamping device is attached. The Specification as open to inspection under Sect. 91 states that the invention may also be applied to " automatic machines for sewing-through." This subject-matter does not appear in the Specification as accepted.

Title: Heat-insulating slabs and their production
IPC: E06B3/70
Filed: 1971-04-19
Abstract: 1328296 Heat insulating slabs SWISS ALUMINIUM Ltd 19 April 1971 [12 Feb 1970] 22633/71 Heading B5N Heat insulating slabs for the production of doors comprises two metal cover sheets 1, 2 each bonded to a layer of heat-insulating material 3, 4, the two layers of heat-insulating material being joined to one another only in a central region so that outside this region each heat insulating layer and its associated metal cover sheet can expand and contract independently of each other, thereby preventing buckling of the slab when exposed to different temperatures on different faces. The heat-insulating layers 3, 4 are preferably separated by a sheet 5, e.g. silicone release paper or smooth polymeric film which facilitates relative movement of the heat-insulating layers, the layers being united through one or more openings into the sheet. Alternatively, the heat-insulating layers may be united to the separating sheet 5 only in the central area. The metal sheets are preferably of aluminium and the heat-insulating layers may be of closed cell foamed granules of polystyrene united by a bonding agent. The slab may be made by forming a layer of loose foamed granules of polystyrene on a metal sheet, wetting the granules with a bonding agent, e.g. an epoxy resin impregnated with a hardener so that the granules become coated with the bonding agent. A fine powder such as mineral powder may then be applied to the layer and the layer is then rendered even and a separating sheet having one or more openings in its central area is laid over the granules. A second layer of granules and bonding agent is formed on the separating sheet and then the second covering sheet of metal is applied and the whole assembly is pressed to form the slab. Preferably the pressing is effected at elevated temperature to accelerate the setting of the bonding agent.

Title: Improvements relating to methods of forming foundations
Inventor: LOWE JAMES NEVILLE
IPC: E02D27/42
Filed: 1957-07-18
Abstract: 835,804. Foundations. PRE-STRESSED CONCRETE CO. Ltd. June 30, 1958 [July 18, 1957; Oct. 1, 1957; Nov. 25, 1957], Nos. 22820/57, 30702/57 and 36703/57. Class 20(2) [Also in Group XXI] A method of founding a permanent structure in soil, wherein a foundation block is dropped and the kinetic energy acquired in falling causes it to penetrate the ground to such a depth as to develop the required load bearing capacity. Two methods of achieving the necessary kinetic energy are described. In the first the block is raised by a helicopter and in the second the block is raised by a gantry only a short distance and is accelerated by rockets. The weight of the block may be increased at the time of dropping by a detachable weight which is subsequently recovered and re-used. The use of such a weight will usually bring the centre of gravity of the block sufficiently near to the bottom to ensure aerodynamic stability, but fins or a drag parachute may be used. Dimensional examples of blocks are given, showing the penetration achieved. The height from which the blocks must be dropped can be determined by dropping small diameter graduated cylinders. Foundation blocks of various shapes are described e.g. flat-ended, pointed, shouldered and with a helical finthe last two intended to have increased resistance to extraction. In cases where a group of foundations are formed with separate foundation blocks 45 and 50 (Fig. 27) to carry a single structure, such as a pylon, the blocks are preferably dropped or projected connected together by chains or ropes 47. As they fall all the blocks are given a rotary movement which causes the blocks 50 to fly out. Rotation is produced by tangentially arranged rockets or inclined fins. A foundation block designed to resist an upward pull is shown at Fig. 30. Two fins 64 lie initially within the chamber 59 with their ends in the slots 60. The block is dropped with parts in the position shown in full lines but after it has penetrated the ground a pull on the cable 62 moves the cone 61 and causes the fins 64 to project from the block. An alternative design, Fig. 33 comprises four similar segments 76 connected by a hinge 77. In the space enclosed by the segments is a plug 79 which can be pulled by the cable 81 to expand the segments. Fig. 36 shows a concrete cylinder 92 which has pivoted fins 94 which rotate to project from the cylinder when it is pulled upward and which are locked in the extended position by grout injected through a duct 98. In a modification the fins are moved outward by a cable operated cam.
