Title: Silicon carbide heating element
IPC: C04B41/50
Filed: 1963-07-12
Abstract: <PICT:1048265/C1/1> A high-temperature heating element of silicon carbide having a porous basic structure is provided with a gas-tight covering layer at least 0.01 mm. thick, also of silicon carbide, to increase the oxidation resistance of the element.  As shown, a silicon carbide element has a porous region 4, a region 3 where the pore space is sealed with silicon carbide, and a covering layer 2 again of silicon carbide.  The element may be of tubular construction (Fig. 3, not shown) or may be of U-shaped bar or plate form.  The element is produced by heating the basic porous body in a gas consisting of at least one silicon compound, e.g. halogen-substituted silanes, and at least one carbon compound, e.g. hydrocarbons, halogenated hydrocarbons, or furfuryl compounds, and/or of at least one organosilicon compound, e.g. alkylsilanes or halogenated alkylsilanes, under a pressure of 0.1 to 10 atmospheres at temperatures above 1200 DEG  C. The concentration and/or the temperature of the silicon carbide supplying substances may be varied during the process so that coarsely crystalline and finely crystalline particles are alternately deposited for the sealing.

Title: Process and apparatus for winding freshly spun untwisted synthetic filaments
IPC: B65H54/28
Filed: 1961-08-01
Abstract: 984, 572. Winding synthetic filaments. BARMER MASCHINENFABRIK A.G. Aug. 1, 1961 [Aug. 1,1960], No. 27915/61. Heading D1J. A thread filament 33 is wound on to a bobbin 1 by oscillating the thread rapidly over a short travel by means of a thread guide member 11 and by slowly reciprocating the bobbin 1 by an initially large stroke that is continuously reduced, the speed of rotation of the bobbin 1 being varied in dependence upon the decrease in stroke or travel of the bobbin or, conversely, the reduction in stroke of the bobbin being controlled in dependence on the speed of rotation of the bobbin that is reduced in a predetermined manner. The bobbin 1 is supported by a carriage 6 that is reciprocated by a piston rod 13 guided in a cylinder 14 of a hydraulic or pneumatic reversal drive means. Below the carriage 6 in a spindle 20 formed with right-hand and left-hand threads and rotatably mounted in bearing blocks 27, 28. As the spindle 20 is rotated, by a motor 29, it causes two threaded slides 18 and 19 thereon to move towards each other, these slides carrying two electric switches 21, 22. The switches 21, 22 are actuated in turn by a cam 32 on the reciprocating carriage 6. Operation of a switch 21 or 22, by the cam 32, causes the piston rod 13 to change its direction of motion and hence the travel of the bobbin 1 is continually decreased.  The switches 23, 24 and 25, of which any suitable number are provided and which are adjustable along a rail 26, are actuated by the slide 18 or 19 or by both slides and serve to vary the speed of the motor 5 rotating the bobbin 1. The switches 23, 24 and 25 can also be used for controlling the speed of travel of the reversal driving gear 15 by acting on the pump delivery thereto or valves therein to thereby vary the flow energy.

Abstract: 224,714. Shanks, J. K. Nov. 13,1923. Valves actuated indirectly.-A valve device for controlling the supply to a cattle-watering trough is actuated by depressing a, nose piece c integral with a vertical lever d. Screwed into the outer valve casing e is an inner casing f having openings g and housing a sleeve k which is screwthreaded internally to receive the spindle m of the valve n. This sleeve k is prevented from rotation by a keyway k<1> and a screw l. The valve spring o presses on a disc p abutting the end of the sleeve k. Adjustment of the valve without removal or without cutting off the water supply is thus possible by rotating the spindle m or by removing the screw and rotating the sleeve k. The vertical lever d is pivoted at d<2> and has a hole r' registering with the end of the spindle m but covered by a member r pivoted to the lever d so that as the nose piece is depressed the spindle m is moved to the left to release water through the spout w. If this member r is swung down to the dotted line position, swinging of the lever d does not operate the valve. The member r is adjusted for wear by means of a screw z in the lever d.
