IPC: H02K7/20
Filed: 1959-03-09
Abstract: 865,135. Motor driving arrangements. DEMAG A.G. March 9, 1959 [March 8, 1958], No. 8089/59. Class 35. A tippler is operated by a main driving-motor 1 and a slow-motion motor 4, both of the slidearmature type, and controlled by limit-switch arrangements. As the drive approaches the stop position, motor 1 is de-energized, clutch 2 engages and motor 4 drives the gearing 8 of the tippler slowly through shaft 6 and gears 9, 7. When the tippler reaches its stop position, motor 4 is de-energized and axial displacement of the rotor shaft causes engagement of brake 5 to stop the drive.

Title: Improvements relating to the making of conduits and to cores for the same
IPC: B29C33/76
Filed: 1924-03-31
Abstract: 228,740. Murray, T. E. March 31, 1924. Moulding in situ.- A rubber core for moulding concrete &c. conduits consists of para rubber to the extent of forty per cent or more, so as to be sufficiently elastic to be detached readily from the surrounding concrete surface and also to regain its normal shape after contraction due to withdrawal from the concrete; when a tubular core is used, the thickness of the material is at least one-eighth of the diameter of the core. The conduits are moulded in sections, the rubber core 2 being pulled to cause it to contract and become detached from the concrete surface 1 and then being placed in position for moulding a further section. The core is formed with a smooth outer surface and may be adapted to form a series of ducts 6, Fig. 3, and also ducts in floors and walls. Means to facilitate withdrawal of the core may be provided in the form of blocks 26, Fig. 7, spaced apart and connected together by a chain 27 which is also attached to a thick rubber tube 28, seured at the end of each of a number of rubber cores arranged in line. The size of the blocks is such as to hold the core distended in use and also to allow the necessary contraction. The blocks 26 also provide means for gripping the core, as by a clamp so as to facilitate withdrawal of the tube, the free end of which may be taken up on a reel. For ducts of oblong cross-section the core and the blocks mav be made of corresponding shape, as shown in Fig. 8. Specification 151,692 is referred to.

Title: Improvements in an arrangement for the working of compressed air jigging conveyor motors
IPC: B65G27/14
Filed: 1932-03-18
Abstract: 397,581. Compressed-air engines for conveyers. KLERNER, H., 164, Schalkerstrasse, Gelsenkirchen, Germany. March 18, 1932. No. 8176. Convention date, March 18, 1931. [Class 122 (ii).] Distribution in a jigging-conveyer motor is controlled by a fluid-actuated main valve 4 in which is housed a fluid- andtappetactuated stem 5 which extends through the valve. The large end of the stem 5 is permanently under pressure. Between the large end 5 and the small end 6 is an abutment which engages the main valve to hold it to the right. The end 5 passes through a valve chamber cover 27 held in position by a spring 25. The main valve is shown stepped ; the forward end controls a port 9 with a branch 9a leading to a small annular area 9b. When the valve is moved to the left, fluid is supplied to the cylinder and moves the piston 2 to the right. The plunger 5 moves to the right until it engages the main valve. When the piston passes port 18, fluid passes to the left of the valve and moves the valve and the stem to the right. Passage 9 is closed and passage 12 opened to exhaust. The power piston 2 is moved to the left by the conveyer. The piston strikes the stem 5, 6, releases the valve, and the pressure fluid supplied by the duct 9b together with compression fluid in the cylinder throw the valve to the left. In a modification the duct 9b is dispensed with. In the construction shown in Fig. 5, the main valve is of hollow cylindrical form and the main cylinder has exhaust ports 31, 32. When the piston passes the port 31, the pressure of fluid on the left-hand side of the valve supplied through passage 16, the fall of pressure on the right-hand side of the valve, and the pressure on the stem, throw the valve to the right. A modification for double-acting motors wherein the plunger 5 controls the admission to the right-hand side of the piston and the main valve controls the exhaust, is described. A pin 28 retains the stem in the valve when the fluid-pressure is cut off.

Patent GB-1094973-A (GB)
Title: Improved method for the production of emulsifiable bitumen and emulsified bitumen produced thereby
IPC: C10C3/04
Filed: 1965-02-26
Abstract: An emulsifiable bitumen is made by blowing an oxygen-containing gas through a heavy petroleum oil at 120 DEG  to 200 DEG  C. to produce an acidic bituminous material containing highly condensed components. A proportion at least of the components may be extracted from the material, and the material, or the extracted components, optionally after mixing with a blown or unblown heavy oil, is mixed with water to form the emulsion.  By "heavy petroleum oil" is meant a solvent extract, heavy naphthenic, aromatic or mixed distillates, distillation residues, and mixtures thereof. Oxidation catalysts may be used to reduce the blowing time, e.g. organic salts or chelates of Group VIII metals, or compounds of Cu, Br, Mn and V, and sulphur compounds may be used to promote condensation.  The blown material produced by the invention may be mixed with other bitumens to make them emulsifiable (Examples 4 to 7), and Example 6 deals with the case in which acid components are removed from the blown material and subjected to further blowing. All examples give details of blowing times and flow rates of the blowing gas.ALSO:A bitumen emulsion is made by mixing with water a bituminous material produced by blowing a heavy oil at 120 DEG  to 200 DEG C (see Division C5).  The bituminous material may be the product of the blowing operation, or highly condensed acidic components extracted therefrom, or the product after extraction of some at least of the components, and a blown or unblown heavy oil or other bitumen may be mixed with the bituminous material prior to emulsifying. Specific examples giving proportions of the mixes and compositions of the resulting emulsifiable bituminous materials are described.  Residues of fatty acids may be incorporated in the bituminous material.

Abstract: 1,027,872. Electric blow - torches. T. KUGLER, and V. VESELY. March 2, 1963, No. 8445/63. Heading H5H. A plasma-jet gun comprises an inner and an outer metallic electrode between which an arc is struck and means for forming a liquid channel surrounding the arc, the liquid serving for generating the plasma and forming a cylindrical seal around the inner electrode preventing the plasma from leaking from the channel past the inner electrode. As shown, an inner electrode 10 is mounted upon a rotating carrier 12 having an integral shaft 14 which runs in bearing 13 in insulating block 7 and an outer electrode 23 is mounted in bearing 19 in block 7 and driven by insulating sleeve 11 mounted in carrier 12. Current is conducted to electrodes 10 and 23 by brushes 15 and 17. Screens 3, 4, 6 are mounted in block 7 and liquid is led into them through channel 21 and tangential orifices 20, 22 to form a liquid vortex through which the arc extends between the electrodes, the liquid passing out through orifice 2 in diffusor 1. Gas is fed through conduit 18. Cooling liquid enters hollow electrode 23 through chamber 24, sealed by packing 25, and passes through channels in carrier 12 into a chamber surrounding electrode 10 and carrier 12 and is rotated by blades 8 on carrier 12 to the periphery of the chamber where it forms a liquid ring to prevent escape of gas from this chamber. The cooling liquid passes out through outlet 16, or if the centrifugal force is sufficient, through channel 5 into the vortex. In a second embodiment, Fig. 2, not shown, the arc extends between the inner electrode and the interior circumferential surface of a ring-type outer electrode supported from the carrier carrying the inner electrode.

Title: Improvements in sliding clasp fasteners
IPC: A44B19/04
Filed: 1952-04-03
Abstract: 723,998. Sliding-clasp type fasteners. MULKA, F. April 3, 1952 [June 14, 1951], No. 8534/52. Class 44. In a sliding-clasp fastener of the kind in which fastener elements 5 are arranged in channels formed by the material 17 (Fig. 1) of the stringer, the elements 5 and surrounding material 17 are embraced by separate stirruplike members 19. The mode of engagement of adjacent elements, under the action of the slide 27 (Fig. 1), is shown in Fig. 2 (in which all other parts of the fastening are omitted). The elements 4 have four inclined faces 11 to 14 as viewed in Fig. 1. At least one of these faces may alternatively be disposed at right angles to the neck 6 of the element 5. The engaging surfaces 8, 9 (Fig. 2) of the elements may be straight, as shown, or curved. A plurality of the elements may be formed by swarfless shaping, machining, or bending from a single bar, as shown in Fig. 3a. The elements may be separated during, or after assembly, of the fastening, by bending or stanping. The assembly may be effected by the action of pressure rollers. The stirrup members 19 may be similarly made and assembled (Fig. 3b, not shown). The inner surface of the members 19 may be roughened, or complementary recesses and projections may be formed on the members 19 and elements 5. The joint at the edge of the stringer material may be secured by sewing, adhesive or solder. The stringer may comprise the actual material which the fastener is intended to join. In a modified construction (Figs. 4a, 4b, not shown), the plane of the free end of each stringer, lies in the plane of one of the outer faces of the corresponding member 19. In a further modification, the slide 27 may engage the outer surface of the stirrup members 19 instead of the elements 5. The end faces of the stirrup members 19, may be inclined with respect to a direction perpendicular to the axis of symmetry of the fastener. By this means, the stirrup members may be made to present an unbroken bearing surface to the slide 27. This inclination may be increased to the extent of making the members 19 of triangular shape.
