Title: Improvements in or relating to Tack-pulling Machines for use in the Manufacture of Boots or Shoes.
IPC: A43D61/00
Filed: 1918-08-22
Abstract: 131,710. British United Shoe Machinery Co., (United Shoe Machinery Corporation). Aug. 22, 1918. Preparing lasted boots for sewing.-In a machine for extracting lasting tacks, a pair of tack-pulling jaws 10, 11 are secured to levers 13, 14, Figs. 1 and 3, loosely fulcrumed on a shaft 19, which is secured at its opposite ends in two parts 20, 21 of a rocker arm 16 depending from an oscillatory shaft 17. The parts 20, 21 are extended beyond the shaft 17 to receive a pin 24, which secures the rocker arm to a rod 23 of an eccentric 25 on a driving shaft 26. The rear portions of the levers 13, 14 carry rolls 30, 31 engaging cam disks on the shaft 26. With this construction, the levers are moved bodily with the rocker arm to carry the jaws towards and away from the shoe, the jaws being opened and closed through the action of the cam disks. Fig. 5 indicates the preferred path of the tack-pulling movement imparted to the jaws, one of which is actuated so that the jaws first grip the shank of the tack, then separate and slide along the shank-, and subsequently grip the tack head or a different point upon the shank to complete the removal of the tack. This causes the upper to be released should it have been accidentally nipped between the jaws. The tacks are guided to the jaws by adjustable work supports 33, 34, Figs. 1 and 4, and the movement of the tacks across the. jaws is limited by a transverse abutment 35. The supports 33, 34 also serve as guards by holding down the upper, while to facilitate the engagement of tacks embedded in the folds of the upper, especially at the toe, the support 33 is adapted to be elevated through connexions 40, 43, 45, 46, Fig. 1, with a treadle so that the shoe may be rocked about the other support 34.

Title: Apparatus for and method of making a heating structure
IPC: B64D15/12
Filed: 1959-04-23
Abstract: 885,131. Laminates. GOODRICH CO., B. F. April 23, 1959 [April 24, 1958], No. 13889/59. Drawings to Specification. Class 140. [Also in Group XI] A laminated sheet-like structure for electrical heating, e.g. such as used for preventing accumulation of ice on the leading edges of aerofoils, is made by bonding together to form a unit, by curing, layers of thermo-setting plastic heat-conducting electrically-insulating material, with an electric heating element disposed between the layers, and then bonding one of the layers to a protective skin by a final cure. The unit may be formed by first bonding one of the layers to a sheet of electrical resistance metal, e.g. aluminium bronze, phosphor bronze, nickel - chromium, nickel - chromium - iron or nickel-copper alloys from which a predetermined pattern may then be removed, e.g. by a photoengraving process, to leave the electric heating element on the layer, and then bonding another layer on the assembly by a second cure. The layers may be formed of a blend of phenolformaldehyde resin with butadiene-acrylonitrile copolymer rubber and vulcanizing ingredients for the latter, and sheets of heat-resistant woven fabric, e.g. of glass fibre, may be embedded in the layers. The fabric and metal sheets may be given a priming coating of the plastic before being bonded together. The unit may be cured flat, e.g. in an evacuated mould having a flexible cover, in an autoclave, and then perforated to provide for venting, bent to conform to a curved protective skin, e.g. of stainless steel, or aluminium alloy, and bonded to the latter by curing in an evacuated rubber bag in an autoclave, or in a mould in which pressure is applied by numerous rigid balls, as described in Specification 885,132; this apparatus can also be used for bonding the structure to the leading edge of an aerofoil. Attaching strips of aluminium alloy may be adhesively bonded to the edges of the completed structure. Instead of making the electric heater element as described above, it may be made by looping preformed wires or strips. Specifications 654,669 and 850,339 also are referred to.

Title: Reducing the intensity of electro-magnetic waves reflected by reflecting objects
IPC: H01Q17/00
Filed: 1943-08-26
Abstract: 581,746. Radio reflection from surfaces, preventing. COLLARD, J. Aug. 26, 1943, No. 13962. [Class 40 (v)] An object normally detectable by radiolocation is rendered substantially non-reflective by dividing its surface into a multiplicity of small areas alternately raised and depressed a distance equal to a quarter wave-length or an odd multiple thereof, so that waves reflected by one set of areas are in opposite phase to those reflected by the other. As shown in Fig. 2, the surface, which may be that of an aeroplane wing or fuselage, has alternate raised areas 4 and recesses 5 which may be in the form of cylindrical cups, a quarter wave-length deep. The recesses may be filled with solid dielectric material to reduce air friction. If material of high dielectric constant is used, e.g. titanium dioxide, the actual depth of the recesses is reduced although that depth still represents electrically a quarter wave-length. To render the object substantially non-reflective over a wide band of wave-lengths, some of the recesses may be of a depth suited to one wave-length and others to other wave-lengths. The area of each recess should be as small as possible but should not be so reduced that the recesses considered as wave guides would not permit the passage of the waves in use. In Fig. 3, the recesses 5 are formed in a sheet of dielectric material 7 which covers the outer surface 4 of the object. The depth of the recesses is such that waves travelling through the dielectric a distance equal to twice the depth of a recess are half a wave-length behind those travelling the same distance in air. The recesses mav be filled with a substance having a different dielectric constant from that of the sheet. The invention is applicable to reflecting objects other than aircraft, for example submarines or the tops of buildings.
