Patent GB-1211633-A (GB)
Title: Resin bonded fibrous boron
Inventor: FINCKE JOHN KIZLER
IPC: C08K9/08
Filed: 1968-01-11
Abstract: 1,211,633. Laminates. MONSANTO CO. 11 Jan., 1968, No. 1747/68. Heading B5N. [Also in Divisions B2 and C3] Laminates comprise fibrous boron with an aromatic polyimide binder (see Division C3). The boron fibres usually have a core of metal or metal boride e.g. W, Ta, Mb or Ti. The boron fibres may be used alone or with other fibres in filament, mat or woven form e.g. a cloth may be woven from a bundle of 2 to 15 boron filaments wound or braided with nylon or polyester or a warp of boron fibres may be woven with a weft of glass fibres. Other fibres mentioned are carbon, silica, silicon carbide or boron nitride. Laminµ of boron fibres may be mixed with laminµ of other fibres e.g. 3 to 30 plies may be formed of glass fibre alternating with or having only the top and bottom layers of boron fibres. In forming the laminates a substrate comprising fibrous boron may have deposited thereon a liquid mixture of a polyimide forming tetracarboxy compound and diamine and solvent and heated to form a prepolymer on the substrate. The so-formed material may be laminated with itself or with other fibrous material similarly coated with prepolymer under pressure at below 500‹ C. e.g. 10 to 10,000 p.s.i. and 150‹ to 350‹ C.

There is reference to production of glycol esters for example bis-(2-hydroxyethyl)-terephthalate from dicarboxylic acids or esters. The glycol may be ethylene, butylene, hexamethylene, 1,2-propylene, or hexahydroxylylene glycols.

Title: Production of filaments or fibres
Inventor: MORLEY JOHN GODFREY
IPC: C04B35/622
Filed: 1965-01-16
Abstract: To produce a fibre or filament, a wire or filament is coated with a ceramic substance which does not have the viscosity range necessary for fibre drawing, by reducing the ceramic substance, e.g. alumina, zirconia or magnesia, to a molten or liquid state and passing there-through a wire or filament to which the molten or liquid ceramic will adhere and/or on which the molten or liquid ceramic will solidify.  The wire or filament is subsequently removed to produce a tube of ceramic material.  The ceramic material may be initially in the form of (i) a tube which is subjected to heat at one end thus forming a blob of molten or liquid ceramic which closes one end of the tube, the wire or filament being passed through the tube and through the molten or liquid blob; (ii) a rod which is subjected to heat at one end thus forming a volume of molten or liquid ceramic through which the wire or filament is passed; or (iii) in powder form and is fed into a shoot, the shoot being heated to reduce the material to the molten or liquid state, and the wire or filament is passed through the molten or liquid material as it issues from the shoot. Further coating or coatings, e.g. of aluminium, aluminium alloys, or the same or different ceramic material as the first coating, may be subsequently applied. The wire or filament may comprise a tungsten wire or a carbon filament.ALSO:To produce a fibre or filament, a wire or filament is coated with a ceramic substance which does not have the viscosity range necesstary for fibre drawing, by reducing the ceramic substance, e.g. alumina, zirconia, or magnesia, to a molten or liquid state and passing therethrough a wire or filament to which the molten or liquid ceramic will adhere and/or on which the molten or liquid ceramic will solidify.

Title: Improvements in Picking or Shuttle Actuating Mechanism for Looms.
Inventor: SMITH ALFRED
IPC: D03D49/46
Filed: 1916-02-15
Abstract: 103,367. Smith, A., and Perks, T. Feb. 15, 1916. Smallware looms. - The usual shuttle-actuating bar is reciprocated by link-work from a crank actuated by continuously rotating wheels of eccentric and elliptical character in such a manner that the bar is caused to dwell at each end of its path of motion for equal or approximately equal periods of the desired length. The bar 2, Fig. 1, is reciprocated on the lay B by a lever 3, an adjustable connecting-rod 7, a bell-crank lever 8, and a connecting-rod 9 from a lever 10 pivoted at 10<a>. This lever is connected by a pin 11<a> and a rod 11 to a crank-pin 11<b> on an eccentric toothed wheel 12 gearing with a similar wheel 15 on a shaft 16, which is driven from a motor shaft 19 by an eccentric wheel 18 and an elliptical wheel 17 twice the size of the wheel 18. The lever 10 is caused to dwell when the crank-pin 11<b> is passing top centre, by reason of the approximate coincidence of the arc c, which is the path of motion of the pin 11<b>, with the portion between the radii a, b of the are d struck with the top or dotted position of the pin 11<a> as centre. An approximately equal dwell at the bottom centre is obtained by arranging the wheels 12, 15, 17, 18 so that the slowest motion of the wheel 12 occurs at this time. The shuttle-actuating bar may act on the shuttles through pins raised and lowered by cam-grooves; or the pins 20, 20<a>, Fig. 4, may be actuated, as the bar 2 moves, by levers 25 engaging crank-pins 26<a> on partly toothed wheels 26 actuated by stationary racks 27. The crank-pins on the wheels may, alternatively, engage slots in the supports for the pins. The parts are adjustable as regards the distance between the pins 20, 20<a>. According to the Provisional Specification, the equal wheels may be dispensed with, and the shuttle-operating lever actuated from a crank-pin on the large elliptical wheel through lever devices suitably arranged to give the requisite dwells.

[Also in Group XXIX] An electrically-controlled servo-control valve having a valve spool 11 operable by differential pressure variation comprises a fluid-isolated electrical motor section 30 with spaced polepieces 71, 73, a rigid member 31 having an armature part 63 extending between the polepieces, a flexure member such as the tube 54 for mounting the rigid member so as to permit pivotal movement thereof, and a fluid-filled section hydraulically sealed from the motor section by the flexure member and including fluid-flow means such as the opposed nozzle 32, 33 responsive to the movement of the rigid member to effect changes in the differential pressure between the fluid-flow means. The rigid member 31 has a flapper portion 58 with flat surfaces 59 which co-operate differentially with the nozzles 32, 33 to control the pressures in chambers 34, 35 at the ends of the valve spool. The flexure tube 50 comprises a thick annular flange 51 secured to a support block 46, a flexible section 54, and a collar portion 55. The tube 50 which may be of beryllium copper is closed at the collar end by a cylindrical portion 60 on the internal part of the rigid member 31, the external part of which has a thick portion 61 of rectangular section tongue adjacent the armature part 63. The arms of the U-shaped polepieces 71, 73 embrace the ends of a coil 70 surrounding the armature part 63. Permanent magnets 77 are clamped between the polepieces by screws 78 passing into the body 1 of the spool valve. The spring rate for the flexure tube is arranged to be the same as the armature rate for the permanent magnets only so that the rigid member 31 will stay in any position within its operating range as long as the coil 70 remains de-energized. When therefore an electric signal is applied to the coil 70 through leads 80, the flapper 58 moves to throttle one of the nozzles 32, 33 and open the other until the pressure differential on the flapper balances the electromagnetically induced torque.

[Class 38 (iv)] [Also in Group XXXVI] Proportioning mixtures.-The electrical conductivity of a flame is employed to determine the oxygen content in the burnt gases or to control the proportion of air supplied to a fuel to maintain a predetermined oxidizing or reducing atmosphere in a furnace. Electrodes 3, 4 are arranged in the flame in circuit with the secondary of a transformer 38 and a resistance. The current in the supply circuit or the voltage across the resistance,-for example, gives a measure of the conductivity of the flame and may actuate a recording or indicating means 10A or a contact device 11B controlling a reversible motor adjusting the air supply valve 16. The fuel supply valve 14 may be controlled to maintain constant furnace temperature. The furnace gases may be drawn at a constant rate by a flow meter through a sampling tube and burnt with fuel supplied at a constant rate through a flow meter to test their quality by means responsive to the current passing between electrodes in the flame. This apparatus may control the furnace air supply in a similar manner to that described.
