Abstract: 1,267,431. Shuttleless looms. VYZKUMNY A VYVOJOVY USTAV ZAVODU VSEOBECNEHO STROJIRENSTVI. 1 April, 1969, No. 17095/69. Heading DIE. In a shuttleless loom of the gripper needle type having needles 1, 2, meeting at the centre of the shed, an inserted weft is held by clamps 18, 19, and moved towards the fall prior to beat-up by the reed 21. The feeder clamp 18 on the entry side of the shed comprises jaws 22 carried by a pin 23 attached to a bar (25) Fig. 4 (not shown) slidably mounted in a support 27 so as to be movable by a cam 14, Fig. 1, towards and away from the fall. A member 31 for opening the jaws 22 is mounted on a firing strip 30 attached to a block 28 which slides with the clamp 18 and is pivotable about the axis of shaft 28 by a cam 15. The taker clamp 19 on the exit side of the shed comprises spring-loaded jaws 32 Fig. 7 which close to grip the uncoiled weft as soon as they are cleared by the head 4 of taker needle 2, the jaws 32 being carried by a bracket 34 slidably mounted on a pin 37 and moved towards and away from the fall by a cam 16. When the clamp 19 reaches the limit of its movement towards the fall, a bolt 35 is moved to the right by an actuator 41 and its conical end opens the jaws 32, the bolt 39 being locked in the position by a spring-loaded detent 44 engaging a recess 46 in the bolt. The jaws 32 remain open on the return movement of the clamp. On the withdrawal movement of the taker needle 2, a cam 48 thereon contacts member 47 to release the detent 44 to allow spring 40 to move rod 39 to the left to release the jaws 32 which are held open until cleared by the needle head 4, whereupon they close to clamp the weft end. A roller 49 carried by the bracket 34 engages in a recess 50 in a stationary member 51 to guide the clamp 32 in its movement towards the fall. The recess 50 may be straight to maintain constant tension in the weft whilst it is held in the clamps 18, 19, or it may be inclined towards or away from the edge of the fabric to move the bracket 34 sideways along its support 35 in its motion towards the fall, whereby the tension of the held weft is respectively reduced or increased.

IPC: B29C53/24
Filed: 1963-05-02
Abstract: 975,615. Moulding elastomeric sheet material; laminates and laminating. AMERICAN BILTRITE RUBBER CO. Inc. May 2, 1963, No. 17322/63. Headings B5A and B5N. A sheet material having a hirsute or suedelike finish is formed by sheet casting a layer of an elastomeric resinous material, hardenable by polymerization, fusion or vulcanization, upon an endless flexible moulding belt 20 having a multiplicity of passages 15 upon its moulding surface. As shown in Fig. 6, a decorative film or layer of ink, for retention upon the finished article, is applied to the moulding surface of the belt 20 by a printer 23, after which a layer of a polyvinyl plastisol 24 is applied by a spreader 25. The belt then passes through a semi-evacuated chamber 26, to completely fill the passages 15 with plastisol and then through a heating chamber 30 to solidify the thus formed layer after which the layer is stripped from the belt. If required, a second layer of material 27 may be applied by a spreader 28. A backing layer, e.g. a textile ply, or a layer of foamed or unfoamed elastomeric material, which is coated with a heat-actuated adhesive and may be embossed or printed, may be applied from a roll 31 by a roll 34 after passing under an infrared, steam, or electric heater 32. The laminate thus formed is passed through a cooler and then stripped from the belt over rolls 35 and stored on roll 36. The moulding belt is formed by pressing a board carrying needles or the like (see Fig. 1, not shown) into a soft substance which may be hardenable to form a primary negative mould from which is produced a series of positive moulds which are conjoined either by cement or a backing layer 10 from a large positive mould. A large negative mould 20<SP>1</SP> of e.g. rubber is then cast from the large positive mould, several such negative moulds being joined to form the moulding belt 20. The passages in the belt may be of different depths in different areas to produce a variegated surface pattern. Specification 929,442 is referred to.

Abstract: 1,262,401. Benificiation of ilmenite; iron oxide. BENILITE CORP. 14 April, 1970 [15 Oct., 1969], No. 17691/70. Headings C1A and C1N. A titaniferous ore or slag, e.g. ilmenite, ilmenite magnetite, ilmenite-hematite, titaniferous magnetite, and titaniferous hematite, is benificiated 'by leaching it in a digester with hydrochloric acid leach liquor, the leaching liquor being heated during this process by feeding into the digester a vapour mixture formed by distilling an azeotropic mixture of HCl -and -water, by which means the HCl content of the leach liquor is simultaneously replenished. The leaching may be .conducted at a pressure of 20-50 p.s.i.g. and a temperature of 108 to 145 C., and the HCl content of the leach liquor may be recovered and reused in the process either as leach liquor or as the source of the vapour mixture. The preferred HCl concentration of the leach liquor is 20% by wt., and the leaching may be performed in two counter current stages. Depending on the ferrie/ferrous content of the ore, it may first be subjected to a reducing step, e.g. with coke at 815 to 1090 C. The iron content of the used leach liquor may be obtained as the oxide by hydrolysis of the chloride at high temperatures, e.g. 260-500 C., by direct contact with combustion gases. This simultaneously regenerates the HCl leach liquor.

Title: Improvements in or relating to balls
Inventor: WATSON JOHN WILLIAM
IPC: B29C43/18
Filed: 1960-05-19
Abstract: A golf ball half shell is moulded (see Division B5) from a polyurethene pre-polymer, that is the starting material prior to curing.  The prepolymers are prepared by reacting an organic polymer containing hydroxyl groups with an organic polyisocyanate or polyisothiocyanate. Examples of such organic polymers include polyesters, polyethers and polyesteramides, all of which must, however, contain residual isocyanate-reactive groups.  Examples of suitable polyesters include polyethylene glycol adipate, polyethylene glycol sebacate, polypropylene glycol adipate and also copolyesters. Examples of suitable polyethers include polyglycols from propylene oxide and tetrahydrofuran. Polyisocyanates which may be used include naphthalene diisocyanates, tolylene diisocianates and diphenyl methane diisocyanates.  Poly-urethane pre-polymers which may be used include Registered Trade Mark "Adiprene" L.167, which is prepared from polytetrahydrofuran and tolylene diisocyanate. Curing is effected by means of cross-linking agents e.g. a substance containing at least two active hydrogen atoms per molecule such as diols and diamines.  The polyurethane pre-polymer/cross linking agent mixture may be admixed with mineral oils, fillers and colouring materials. In the example of the process given titanium dioxide (anatase) was dried at 140 DEG C. for 1 hour.  On cooling to room temperature in a closed container the titanium dioxide was mixed with twice its weight of methylene bis (orthochloranilene) (MOCA), as a cross-linking agent, and the mixture milled for 24 hours.  The mixture was then heated in an evacuated vessel to 140 DEG C. to remove dissolved gases, the mixture being subsequently stored in an oven at 110 DEG C. in a sealed container.  30 parts of the mixture at 110 DEG C. were stirred with 100 parts of Adiprene L.167.  After moulding of the ensuing mixture, the mixture was cured for 10 minutes between platen heated to 105 DEG C. and 100 DEG C. under pressure, the mould then being brought to room temperature in about 7 minutes.  The mould was then transferred to an insulated box containing solid carbon dioxide, the mixture being taken from the mould when its temperature had fallen to about -12 DEG C. and stored in a metal container surrounded by solid carbon dioxide. The mixture was finally cured between platen at 100 DEG C. for 15 minutes under pressure, the mixture being then cooled to room temperature again in about 7 minutes.  The final curing time was varied, a resulting property being given in the Specification in tabulated form.

Title: Braking installation for lorries and trailers
IPC: B60T11/10
Filed: 1955-06-21
Abstract: 782,391. Tractor-trailer brake systems. TEVES, H., and TEVES, E. A., [trading as TEVES MASCHINENUND ARMATURENFABRIK KOMM.-GES., A.]. June 21, 1955 [July 14, 1954], No. 17932/55. Class 103 (1). An hydraulic brake system for tractor-trailer vehicle combinations includes a device inserted in the conduit between the master cylinder 1 and the brakes on either the tractor or trailer vehicle which has the effect of producing an initial simultaneous application of the brakes of both vehicles, but in which the trailer vehicles brakes are applied more strongly than the tractor brakes, followed by a gradual equalization of the braking pressure. As shown in Fig. 1, a conduit 4 leads directly to the trailer brakes 5 from the master cylinder 1 but fluid to the tractor brakes 7 must pass a spring-loaded ball valve 12. The opening of the ball valve 12 depends upon the relative movements of pistons 8 and 15, that of piston 15 being fairly rapid initially due to the characteristics of springs 16, 18 which become stiffer as compression proceeds thus making the ball valve 12 open more easily. In the arrangement shown in Fig. 2, the trailer brakes 25 are again applied directly from the master cylinder, the brake cylinders thereon being larger than on the tractor. The tractor brakes are applied by a stepped piston device which originally gives a 1: 1 pressure ratio, this being increased later by opening of ball valve 43 by piston 38 to give a stepped-up pressure ratio which brings the braking force on the tractor substantially equal to that on the trailer. In a further embodiment the master cylinder is connected directly to the tractor, a stepped piston being inserted in the conduit to the trailer brakes which first applies the brakes thereon at an increased pressure ratio, this ratio being later reduced to 1: 1 ratio.
