Title: Motor-driven positioner
IPC: F16L3/215
Filed: 1960-09-12
Abstract: 922,703. Automatic control systems for pipe hangers. GRINNELL CORPORATION. Sept. 12, 1960 [March 23, 1960], No. 31288/60. Class 38 (4). [Also in Group XXIX] In a motor-operated positioning device, parts of a fluid conducting system are positioned by a jack comprising a first part mounted on a frame and a second part movable linearly relative to the first part by a variable speed motor, the speed of which is controlled in dependence on the rate of change of a condition of the system, the condition being for example, the temperature of the system. As shown, a section 186 of a pipe, subject to movement due to change in temperature of a fluid flowing through it, is maintained horizontal by supporting the section by a hanger 184 positioned by a jack 180 driven by a motor 182. The section 186 is connected by cords 190, 192 to a differential 188, an arm 198 of which is positioned in dependence on the deviation from the horizontal. A contact 203b on the arm 198 engages a contact 217a or 217b in dependence on the sense of the deviation to control the direction of rotation of the motor through a contactor 222 so as to tend to correct the deviation. A further contact 203a on the arm 198 engages contacts on banks 200, 202 in dependence on the sense and magnitude of the deviation. Each contact of banks is connected so as to energize a corresponding relay coil such as 208 so that for small deviations the field current of the motor is a maximum and the rate of correction low and for a large deviation a portion of a resistor, such as 232, is inserted in the field circuit to increase the motor speed and rate of correction. In a modification, the contact 203b is dispensed with and the contactor 222 has a plurality of coils energized in parallel with the relay coils. In a further modification for maintaining the tension in the pipe hanger constant, deflection of a spring moves a contact over rheostats in the field circuit of the motor and a further contact energizes the contactor controlling the direction of motor rotation.

Title: Improvements in laminated sheet material
IPC: B32B27/00
Filed: 1963-08-12
Abstract: 1,024,658. Roof structures. RUBEROID CO. Aug. 12, 1963 [Jan. 21, 1963], No. 31802/ 63. Heading E1V. [Also in Division B5] A waterproof, non-inflammable, flexible sheet material suitable for applying to existing roof decks or to a rigid base to form panels comprises a substantially opaque, 1-4 inches thick, film of polyvinyl fluoride bonded by means of a thermosetting elastomeric adhesive to a backing layer of asbestos felt impregnated with 15-25% by weight of a non-inflammable elastomeric binder such as polychloroprene or a mixture of polychloroprene with acrylonitrile in the ratio 1:1 to 1:3. The film is rendered substantially opaque by the inclusion of up to 25% of opacifying pigments such as titanium dioxide and carbon black. Suitable adhesives, which may contain up to 10% of carbon black, include acrylonitriles with phenolic tackifiers and an isocyanate curing agent, or polysulphides. In an embodiment (Fig. 3, not shown), a wood or concrete roof deck is covered, by means of asphalt 18, with lengths 19-22 of conventional coated, sanded and asphalt-saturated base sheet, the overlapping portions being nailed to the deck. Lengths of the sheet material as above are then applied, film uppermost, to the base sheet by hot asphalt or cold cement adhesives. Side and end overlapping of the latter sheets may be achieved by providing a film-free edge 16 on each length, such edges being coated with adhesive to within one inch of the edge of the film. Alternatively, the lengths may simply abut each other. The seams are then sealed by using pressure-sensitive polyvinyl fluoride tape or by caulking. In a further embodiment, rigid panels are produced by applying the sheet material, e.g. by means of asphalt, to a rigid insulating base such, as wood, including bonded shredded wood, shavings or paper, or slabs of vermiculite, stones or gravel bonded with cement, with or without the addition of other light aggregates,

Title: Improvements in or relating to machines for lasting boots or shoes
IPC: A43D113/00
Filed: 1934-11-09
Abstract: 447,062. Sewing-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., Belgrave Road, Leicester.-(United Shoe Machinery Co. de France ; 5. Rue de Dunkerque, Paris) Nov. 9, 1934, No. 32214. [Class 112] Machines for stitching " veldtschoen " uppers to soles of the type described in Specification 361,336, are provided with means for rendering the auxiliary positioning means for the shoe upper operative or inoperative without affecting other adjustments of the machine. The action of the auxiliary positioning means is described in Specifications 20047 /14 and 176,496, [both in Class 112]. The knee-lever actuation of the upper-stretching grippers is described in Specification 22110/13, [Class 112]. As illustrated, the machine comprises the usual curved hook needle, curved awl 2, looper 4, shuttle 6, thread arm 8 and a thread-measuring device oscillated from a three-armed lever 10 pivoted at 12 and carrying a cam roll 14 by which it is operated from a cam on the main shaft 16. The machine further has an upper-stretching gripper with jaws 18 and 20 operated in the usual manner. The shoe positioning means comprise a presser foot 22 engaging the margin of the sole, and auxiliary positioning means comprising the member 24 carried at one end of a curved arm 26 of a bell-crank lever, the other arm 30 of which is pivoted to the link 5. When the hand piece 50 is moved rearwardly, a lug 42 is raised to lift the latch bar 23 and raise the cam lever 31 a sufficient distance to bring its cam-surface into contact with the roll 32. In this position, the plate 40 is in its anticlockwise position and engaging the stop stud 52. The oscillations of the threearmed lever 10 cause the link 19 to oscillate idly about its pivot 33, the roll 32 of the pivot being held against the lever 31 by the spring 35, and the latch bar 23 being held above the plate 43 by the lug 42 so as to avoid obstructing these oscillations. Thus the actuating lever 5 of the auxiliary positioning means derives no movement from the link 19. When the hand piece 50 is pulled forwards, the plate 40 is moved clockwise and the lug 42 pulls down the lever 31 through the link 54. The roll 32 engages the upper part of the cam surface of the lever 31 and causes the stud 33 to be moved forward carrying the link 5 so that in the next anticlockwise oscillation of the lever 10, the latch bar 23 snaps down into the angle between the shoulder 49 and plate 43 under the action of the spring 25. The three-armed lever 10 then oscillates the stud 33 and the fulcrum of the link 19 becomes the pivot 51 which is held stationary by the latch bar 23. The auxiliary positioning means 24 is then oscillated by the link 19 through the link 5. A return movement of the hand piece causes the lug 42 to lift the latch bar and return the parts to inoperative position.
