Abstract: 1486244 Pneumatic tyres UNIROYAL 29 July 1974 [27 July 1973] 33486/74 Heading B7C A pneumatic tyre has a breaker 17, and annular circumferentially extending protuberances 24, 25 projecting axially from the shoulders of the tyre, the lateral edges 17c, 17d of the breaker being located within the protuberances, and the radially outer surface 26-28 of one protuberance 24 being radially recessed from the transverse profile of the radially outer surface 27a of the tyre tread 11. As viewed in radial cross-section with the tyre in the inflated but unloaded state, the radially outer surface of the breaker 17 follows a smooth radially outwardly convex curve with a curvature less than that of a radially outwardly convex curve which is described collectively by the radially outer surfaces of the tread and protuberances and which extends smoothly from the axially outer extremity of the radially outer surface of one protuberance to that of the other protuberance, notwithstanding the fact that the surface 26-28 is set back from this curve. As shown in Fig. 3 the tread 11 may have a pattern of circumferential ribs 31 separated by zig-zag grooves 33, "W"-shaped sipes or grooves being provided in the ribs 31. The protuberance 25 has a pattern composed of transverse blocks 35 which are connected to one another in their axially outer regions and separated from one another in their axially inner regions by transverse grooves 36 running into a zig-zag circumferential groove 36a at the boundary between the protuberance 25 and the tread 11. Zig-zag transverse sipes or grooves 37 are provided in the blocks 35. The protuberance 24 is patterned in its axially inner region with blocks shaped as shown and containing right-angled grooves, but is otherwise unpatterned. The breaker 17 may comprise two layers 17a, 17b of cord fabric whose cords are either parallel to the mid-circumferential plane X-X of the tyre or cross-laid at an angle of 15-30 degrees to the plane X-X. The carcass 12c may comprise a single ply of radially disposed cords made of an aramid fibre, or alternatively may be of cross-ply construction. The tyre beads may be reinforced with apex strips 19, 19a, flipper strips 20, 20a, and chafer strips, and may be covered on their external surfaces by hard rubber strips. Indicia means may be provided on the tyre to indicate that the side having the protuberance 25 is intended to be the outboard one in use.

Title: Device for gripping yarn ends
IPC: B65H67/08
Filed: 1975-08-12
Abstract: 1482861 Gripping yarn ends ELITEX 12 Aug 1975 [12 Aug 1974] 33550/75 Heading D1J The invention relates to means for use in automatic winding machines in which yarn is wound onto large bobbins from successively presented small cops, and comprises means for gripping a yarn end housed in a tube of a cop and transferring the yarn end to a knotting mechanism. In Fig. 1 the yarn gripper 1 is carried by an arm 14 having a part 3 that is rotatable in bearings 5 in a pneumatic chamber 1. A radial opening in the part 3 enables air to be sucked through the arm 14 into the chamber 1. An automatic knotting mechanism controls a cam 12 to cause the gripper 1 to be moved from its lower broken line setting to its upper broken line setting when a yarn end has to be drawn off a bobbin 22 for knotting purposes. According to the invention the gripper 1 comprises a sliding insert 16, Fig. 2, that is biassed to the right in the drawing by a spring 17. Slidable in the insert 16 is a bush 19 that is biassed to the left in the drawing by a spring 21, the bush 19 carrying a socket 18. Rotation between the parts 16, 19 and 14 is prevented by a pin and elongated slot connection 20. When the arm 14 swings the gripper 4 downwardly in Fig. 1 into engagement with the bobbin end, the bush 19 is pushed axially into the insert 16, as in Fig. 3, to cause a port in the socket 18 to be aligned with a port in the insert 16 and the bore of the arm 14. The yarn end can thus be sucked off the end of the bobbin 22. As the gripper swings upwardly the components thereof assuming the relative settings shown in Fig. 2 whereby the yarn end is gripped and drawn upwardly with the gripper. When the gripper reaches its uppermost setting the insert 16 strikes against a stop 23, Fig. 1, and this causes the components of the gripper 4 to assume the relative settings shown in Fig. 4 whereby the yarn end is released for knotting purposes. Fig. 5 (not shown) illustrates a modification in which the gripper is not mounted on a rotatable arm 14 but is displaceable in a linear direction by piston and cylinder means.

A machine for forming a stack of pallets, each loaded with a concrete slab, includes a support for the loaded pallets at one station adjacent a support for a stack of empty pallets at another, the stations being aligned with a pick-up station, overhead pick-up means travelling between the stations and being arranged to deposit an empty pallet on the stack while a slab is being engaged at the pick-up station. The supports comprise each opposed girders 27 moved stepwise on vertical rail members by a chain &c. 50 and a pneumatic &c. motor 55 and one-way clutch 53. The supports for the loaded pallets move in synchronism with but in the opposite direction to those for the empty pallet stack. Suction, magnetic or other pick-up heads 19, 20 are movable vertically on a carriage 15 which travels along horizontal rails between the stations. Conveyers 41, 42 feed in the empty pallet stack and remove the loaded pallet stack respectively, the supports 27 descending beneath their upper surfaces to permit this. As the head 20 is picking up a slab 80 from a moulding unit 2, so the head 19 is depositing a pallet 70 on the loaded pallet stack. As the carriage returns, the head 19 is positioned to pick up another pallet and the head 20 to deposit a slab on the last deposited pallet. Stepwise movement of the supports accompanies the above operations until feelers responsive to a given height of loaded stack, or a programmed control unit cause discharge of the stack and/or replacement of the empty pallets.

[Class 82 (ii)] In a method of separating solid materials by sink and float principles, the heavy liquid is admitted at a plurality of levels below the feed entry for solids and at points horizontally distributed at each level so as to impose a slight upward current of substantially uniform strength throughout the body of heavy liquid in the vessel. The crushed ore is fed into a shoot c and distributed into the heavy liquid by the rotating vane d. The tailings removed by the conveyer e are passed over a draining screen f to a discharge shoot g. The concentrates removed by the conveyer k are discharged through the shoot l. The heavy liquid is led in by a series of pipes m which terminate in horizontal rows of inlets at different levels and on opposite sides of the vessel extending to the lower portion of the vessel and producing a substantially uniform vertical current. The inlet nozzles slope down and open beneath inclined plates p for spreading purposes. The fluid is supplied through pipes t and u preferably supporting equal columns of liquid. A swingable plate device x distributes the fluid. Pipes 7 may provide jets of compressed air or heavy liquid to loosen the sink material. Overflow weirs 8 may control the liquid level and the overflowing liquid together with that draining from the discharged material may be led to the screen 10 and delivered by the pump 3 to the inlet columns. The concentrate may be further purified by jig washing, " classifying '' thickening and flotation. In the case when the suspension solid is the same as the concentrate, the purified concentrate (e.g. galena) may be used for replacement purposes and the impure suspension disposed of.

Patent GB-390523-A (GB)
Title: Manufacture of organic bases
Filed: 1931-07-04
Abstract: Organic bases are produced by condensing ammonia with unsubstituted dichlor- or dibromhydrins of polyhydric alcohols which have no side chain in presence of water as solvent, in which the temperature is allowed to rise above 100 DEG  C. during the reaction.  In an example aqueous 23 per cent ammonia is added to a -dichlorhydrin in a pressure vessel without supplying heat; the reaction being exothermic, the temperature rises to 110-120 DEG  C. and the mass is allowed to cool spontaneously.  Ammonium chloride crystals are removed, and the solution is evaporated under reduced pressure at 30-40 DEG  C., kneaded with alcohol, and dried again. Instead of glycerin dichlor-or dibrom-hydrins, dichlor- or dibrom-hydrins of other polyhydric alcohols such as erythrite and mannite may be used.

Abstract: 325,809. Hereng, A. J. A. Nov. 23, 1928. Retorts; coking processes.-In the distillation of solid fuel such as coal, lignite, or peat in a continuous process, the fuel is dried, is distilled on an endless permeable grate, and the residue is cooled by gases which are heated and circulated through and over the charge, and through the drier back to the cooling chamber. Fuel from a hopper 2 is fed to a drier 1 through which it passes from shelf to shelf, the shelves 4 being mounted on a rotatable hollow stem 3 and the shelves 5 being stationary. The fuel, heated to 200‹ to 275‹ C. and to near its' softening temperature, passes through a conduit 10 to an endless conveyer 17, the depth of the layer being controlled by a slide 18. Hot gases pass over the charge in a counter current and are drawn through it by a fan 28 and through a condenser 26 and purifier 29 from which a pipe 30 leads away non- condensable gases, a part of these being used in a burner 32 to heat a radiating plate 24 and pipes 35 in which the distilling gas is heated. The residue passes to a cooling chamber 45. Hot gases from the distillation chamber 12 circulate through a conduit 37, drier 1 pipe 13, fan 14, purifier 15, pipe 41 to which fresh steam is admitted by pipe 42, and chamber 40, from which they pass through and are heated by the grate 17 and fuel thereon, the heated gases then being further heated in pipes 35 before entering the distilling chamber 12. The coke or residue may be burned while still on the conveyer, or may be used in a gas producer.
