Title: Improvements in or relating to Conveyors.
Inventor: THOMSON CHARLES
IPC: B65G17/42
Filed: 1965-11-15
Abstract: 1,164,995. Endless conveyers. SOLAR THOMSON ENG. CO. Ltd. 11 Nov., 1966 [15 Nov., 1965], No. 48485/65. Heading B8A. An endless conveyer comprises a plurality of carrier plates 10 which are supported and frictionally driven by cables 15 and are interconnected by links 17, there being resilient pivotal means 25 between the links 17, whereby the distance between the centre points of adjacent plates can vary. Each plate 10 has a base 11 and sides 12 and is rigid with a supporting cross-rod 13 at its trailing end. The latter carries shoes 14 which bear on the cables 15 and the ends of the rod 13 from pivots within respective 0-rings 25 (Fig. 16). Each 0-ring is disposed within a housing 27 carried at the end of the link 27. The other end of the link 17 respective to the next adjacent plate 10 is centred on the outer end of the rod 13. Under conveyer load the O-ring distorts (Fig. 17) to permit extension of the endless train of plates 10 in accord with extension of the supporting cables 15. The 0-ring 25 and links 17 are retained on the end of the shaft 13 by an elongated retaining plate 26 (Figs. 5, 16) carried by the shaft end. A slot 29 formed in the aperture 28 of the outer link 17 end, is normally out of alignment with the plate 26. By placing two adjacent plates 10 and their associated pairs of links 17 at right angles, the plates 17 may thus be assembled on to or detached from, the rod 13. At its leading end, each plate 10 rests on, and is supported by, the end of the next adjacent plate 10 (Fig. 15). On the lower run of the conveyer, the leading end of each plate 10 is prevented from falling down by a portion 22 (Fig. 15) which engages the rod 13. As the plates 10 pass around the return drum 19 they are cleaned by a scraper (24) (Fig. 7, not shown). The ropes 15 are wound with several coils around driving and return drums 21. The shoes 14 are designed to turn under gravity so that their grooves remain facing downward on both conveyer runs. Alternatively they may be formed with upper and lower oppositely facing grooves or alternate shoes may be inverted. According to a further alternative the shoes may be turned into proper position by contact with a cable. The 0-rings 25 may be replaced by metal springs. In a modification, the resilient means 25 may be disposed at the middle of each link 17. The rod 13 may be replaced by a coaxial tube and rod assembly.

A system for maintaining the running temperature of a diesel engine includes a valve 10 operable to inject fuel into the airstream 12 in the inlet manifold of the engine when the running temperature falls below a predetermined value and a heating coil 13 to ignite the injected fuel in the manifold. The valve 10 comprises a body 14 with an injection orifice 15 at its lower end through which fuel can pass from a chamber 16 and duct 17. A spool 18 slidable in the body 14 closes the orifice 15 with its tapered end 20 when it is urged downwardly by a spring 21. A switch 25 is controlled by a thermosensitive device responsive to the water temperature in the engine cooling system so that when the temperature falls below a predetermined value the switch 25 closes to energize a solenoid 23 around the valve body 14 to raise the spool 18. At the same instant the heating coil 13 is energized to ignite the fuel injected through orifice 15 to thus pre-heat the air supply to the engine. The fuel may be supplied to valve 10 by a pump or from a reservoir.

Abstract: 1404290 Chemically finished carbon filaments BAYER AG 24 Oct 1973 [24 Oct 1972] 49422/73 Heading C1 [Also in Divisions C3 and C7] Carbon filaments are covered by a polymer skin comprising polymerized olefinically unsaturated monomers, the polymer skin having a thickness of from 50 to 10,000 nm. Preferably the filaments consist of more than 80% by weight of carbon and have oriented turbostratic structures in which the normals of the 002-lattice planes have a preferred direction perpendicular to the fibre axis, and the polymer skin comprises polymerized vinyl and/or vinylidene monomers, or polymerized diolefins. Such filaments are made by reacting carbon filaments in the presence of at least one olefinically unsaturated monomer in an electrical field in such a way that a transport of charges is produced. In apparatus as shown, carbon filaments 8 pass around graphite roller 4 and plastics rollers 5, 6 and 9, and are immersed between rollers 5 and 6 in the bath 1 of electrolyte 2. In examples this is a mixture of acrylic acid, methyl methacrylate and tertiary butanol or of acrylic acid and water. Current measured by ammeter 11 is supplied by power pack 10 to graphite roller 4 and hence the carbon filaments as anode, and to graphite board 2 as cathode. The voltage between graphite roller 4 and calomel electrode 13 is measured by voltmeter 14, which effectively indicates the voltage between the carbon filaments 8 and electrode 13. Nitrogen, or gaseous monomers, may be bubbled through the bath, which can be maintained at from -50‹ to +200‹C. After passage through the electrolysis bath, the filaments have an extremely thin skin of the copolymer of acrylic acid and methyl methacrylate or of polyacrylic acid, depending on the electrolyte used, visible through interference colours. Filaments so made have tougher tensile strength than the starting filaments and may be impregnated with epoxide or polyester resins to produce composite reinforced plastics materials having interlaminar shear strengths approaching that of the pure resin. In a typical example, filaments of tensile strength 2À3 GN/m.<SP>2</SP>, density 1À85 x 10<SP>3</SP> Kg./m.<SP>3</SP> and breaking elongation 1À0% are treated to give coated filaments of tensile strength 2À7 GN/m.<SP>2</SP> and breaking elongation 1À1%.
