Title: Oriented Concentric Sheath-Core Filaments and Pneumatic Tires Reinforced therewith
Inventor: PIERCE NORWIN CALEY
IPC: B60C9/00
Filed: 1968-01-31
Abstract: 1,165,853. Oriented concentric sheath-core filaments. E. I. DU PONT DE NEMOURS & CO. 31 Jan., 1968 [31 Jan., 1967], No. 5015/68. Heading B5B. Oriented concentric sheath-core filaments suitable for tyre reinforcement comprise a sheath of a synthetic linear aliphatic polyamide having a melting point of at least 180‹ C. and a glass transition temperature (Tg), less than 100‹ C. and a core consisting of a polyamide having recurring aromatic or cycloaliphatic rings as an integral part of the main polymer chain and having a Tg of at least 140‹ C., or a polyester having an initial modulus of at least 60 grams per denier. The filaments comprising at least 30% and preferably about 40-70% by weight of sheath polymer and the remainder core polymer. The melting point of both polymers should not exceed 350‹ C. In an example, molten polyhexamethylene adipamide having a relative viscosity of 45 and molten polyethylene terephthalate having a relative viscosity of 30 are simultaneously extruded at the same volumetric flow rates through each of the extrusion surfaces of a spinneret assembly adapted for the melt-spinning of concentric sheath-core filaments to form 34 sheath-core filaments with the polyamide as the sheath and the polyester as the core. The filaments are air quenched and drawn at a stretch ratio of 5À8 over a snubbing pin at 100‹ C. and a hot pipe having a surface temperature profile of 150/ 170/190‹ C. to give a yarn having a denier of 216. Using conventional procedures except as noted, the yarn is converted into an 1800 denier tyre cord, dipped, dried at constant length, hotstretched 5% at 200‹ C. and built into an 850 x 14 4-ply tyre. The tyre is cured by heating in a press at 130-147‹ C. for 20 minutes. The partially cured tyre is then inflated to 48 p.s.i.g. and placed in an oven at 139-159‹ C. for 45 minutes. A flat-spot is produced in the tyre by inflating to 22 p.s.i.g., heating to 77‹ C. and then loading the tyre to 1086 pounds for 2 hours, i.e. until the tyre has cooled. The radial deformation in mils, is measured as the flatspot depth and in this case was found to be 124. In another example, 50-50 sheath-core filaments are similarly formed, the core in this case being a polymer (PACM-12) of 57 relative viscosity prepared from dodecanedioic acid and bis - (4 - aminocyclohexyl) - methane having a trans-trans isomer content of 70% by weight. The flat spot produced in the tyre following the procedure of the previous example is 133 mils.

Abstract: 1529503 Engine turning gear; I C engine power plant M E WALLIS 13 Feb 1976 [12 March 1975 26 Jan 1976] 05692/76 Headings F1K and F1Q In an I.C. engine power plant comprising a primary engine 10 and at least one auxiliary engine 12, the primary engine is started by conventional means and the auxiliary engine by means of an energy storing device, e.g. flywheel 14, driven by the primary engine and connectable to the auxiliary engine, e.g. by clutch 17. As described, the flywheel is coupled to the primary engine by a second clutch, and both clutches are of the fluid slip type under the control of an accelerator pedal 26. The auxiliary engine may be controlled automatically in response to a signal from a torque sensor 22 on the primary engine drive-shaft 20 driving a hydrostatic transmission 18, so as to start and connect the auxiliary engine to drive in tandem with the primary engine. Again, starting of the primary engine may require simultaneous depression of pedal 26 and turning of the ignition switch and starter. On subsequently stopping and raising the pedal 26, both engines will stop and may be restarted by the flywheel. The engines may be the same or different, and may be reciprocating or rotary. The energy storing device may be a heavy flange on a single clutch between the primary and auxiliary engine, Fig. 5 (not shown). Again, Fig. 6 (not shown), the clutches may be electromagnetic. Also Fig. 7, (not shown), an underspeed detector (216) is effective to sense a fall in the speed of the flywheel such as to render it incapable of bringing the auxiliary engine up to starting speed. When this fall is detected, the flywheel is automatically connected to start the auxiliary engine which brings the flywheel back up to speed. The auxiliary engine is prepared for starting by being heated by the primary engine, e.g. by sharing a common water cooling system or by utilizing primary engine exhaust.

Title: Improved manufacture of cellulose derivatives which are soluble in cold water
IPC: C08B11/20
Filed: 1937-02-25
Abstract: Fibrous cellulose derivatives are obtained in a form readily soluble in cold water to give homogeneous solutions by partly or wholly dissolving in water, and evaporating the solvent so that a residue is obtained in the form of threads, shreds or particles having a reduced rate of solution in cold water relatively to the starting material. The residue may be obtained from thin sheets or threads which are then mechanically subdivided, or in the form of a fine powder by atomization drying, or as a precipitate by adding an aqueous solution to a heated liquid non-solvent.  In examples: (1) a solution of methyl cellulose in water is added in drops to tetrahydronaphthalene at 160-175 DEG  C.; a coarse powder of dry methyl cellulose is obtained, which is filtered off, washed with alcohol, dried and ground, whereby it is readily soluble in cold water without formation of lumps; (2) a solution of methylethyl cellulose in water is sprayed on a smooth surface and evaporated to produce a thin film, which is crushed to a coarse powder; (3) a solution of methyl-hydroxyethyl cellulose in water is converted into a fine powder by atomization drying, the powder sprayed with 50 per cent alcohol, dried with agitation and crushed; (4) an ethyl cellulose solution in water is spun into threads and the dried thread cut into short pieces. Specification 6035/13, [Class 2 (ii)], is referred to.

[Classes 83 (ii) and 83 (iv)] Destructible mandrels; uniting by fusion.-In the manufacture of electron discharge devices a hollow mandrel of destructible material is inserted within a coiled filament, through the mandrel is passed a centring rod projecting from a stem carrying lead-in wires, the ends of the filamenteare welded or otherwise secured to the leadin wires and the mandrel is then removed or destroyed in situ. The material of the mandrel may consist of a.hardened mixture of flour and water of the consistency of macaroni, or may consist of polystyrene or celluloid, or of hardened plastics sold under the Registered Trade Marks " Bakelite ", " Catalin ", " Plexiglass", " Pyralin", " Tenite " or known under the trade name " Sucite", or may consist of other materials such as wood, plaster, clay, glass and destruction may be effected by chipping, breaking, splitting, burning, sintering, or immersion in water or other fluid. The hollow mandrel 21 is first inserted into the coiled filament and then passed over the central rod 19 of the mount, the end of the coil 20 being of reduced diameter to fit the rod. The ends 16 of the filament are then welded to the lead-wires 17 and the mandrel then removed by disintegration without damaging the filament and so as to retain it coaxial with the rod. Disintegration may be effected by incorporating the assembly in the electron discharge device and then placing in an oven or by heating by induction while on exhaust so as to burn the mandrel out, or the mandrel may be slid down the rod before inserting in the discharge device to a position below the coil and there crushed by a pair of pliers. In another form, the mandrel may be burnt away by applying electric current to the lead-in wires and to the rod 19 either before or after placing the mount in position. In a further form, the mandrel may be soaked in water which causes it to swell and soften and then either unscrewing it before it becomes too soft or brushing it away from between the convolutions of the coil.-
