Filed: 1924-03-11
Abstract: 221,180. Wiegand, E. L. Aug. 31, 1923, [Convention date]. Wire and ribbon resistances, embedded and encased.-In an electrical heating element of relatively thin cross-section and large surface area and wherein a resistor is enveloped in refractory material within a sheet metal casing, the refractory material, such as magnesium or zirconium silicate, to which may be added clay as a binding medium, is highly compacted about the resistor by pressure. As illustrated in a strip type of heating element the resistor 1, preferably in zig-zag form, is embedded in compacted refractorv matetrial 2 within a metal casing composed of a channel receptacle 5 having sides 7 which are bent over a cover 6. Terminals 3, preferably of the type described in Specification 219,084, [Class 38 (i), Electric couplings &c.], are provided, and the ends of the casing are flattened at 8 and provided with hole 9 for attaching the element to the article to be heated. A portion of the casing may be perforated and the strip may be bent to various shapes. Other shaped heating elements are described, and the walls of the casing may be connected by eyelets. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a process for preparing these elements wherein the receptacle 5 is first partly filled with refractory material, the resistor is inserted, preferably by means of the apparatus described in Specification 221,894, [Class 87 (ii), Moulding plastic &c. substances]. the receptacle is filled with refractory material and pressure is applied. The cover is next put in place, the edges of the receptacle are bent over, and heavy compacting pressure applied. This subject-matter does not appear in the Specification as accepted.

Patent GB-141169-A (GB)
Title: Improvements in railway brake valves
IPC: B60T15/02
Filed: 1919-03-13
Abstract: 141,169. McIntosh, J. M. March 13, 1919. Fluid-pressure.-Relates to a triple valve for railway fluid-pressure brakes, of the type in which a piston 2 is mounted in a cylinder 1 and capable of movement relatively to a piston-ring 4 located in a groove 3 in the piston, the cylinder being connected at 10 to the train-pipe, at 7 to the auxiliary reservoir, at 11 to the brake cylinder, and at 13 to atmosphere. According to the invention, the piston 2 is made hollow so as to serve as a local-venting chamber for the trainpipe during an application of the brakes. When the train-pipe is charged, the piston is raised, allowing the auxiliary reservoir to be charged by way of ports 8, 7, and the brake cylinder to exhaust through ports 12, 3, 13. When the pressures equalize, the piston falls until the upper edge of the groove 3 contacts with the ring 4, the friction of which prevents further lowering of the piston. When train-pipe pressure is reduced, the friction of the ring 4 is overcome and the piston lowered to admit air from the auxiliary reservoir to the brake cylinder through small ports 6a, 6, and the train-pipe vents into the piston chamber by means of ports 9, 5. In the lap position, the piston chamber is exhausted by ports 5, 13. In an emergency application, the piston falls sufficiently to uncover the brake-cylinder port 12 fully.

Abstract: 560,751. Pneumatic, rotary and screw conveyers. WESTBERG, E., and SWARTHE, L. L. May 18, 1942, No. 6706. [Class 78 (i)] Rotary pick-up and screw-conveyer means for introducing material such as saiid, gravel, grains, copra, &c., into a blast pipe line consists of a portable head 10 which is slung by hooks 60 to rest on the surface of the material located in the hold of a ship &c. A plurality of scoops 36 are arranged radially around a rotary member 30 located concentrically with respect to the head, the upper half of which consists of an enclosing casing 14 and the lower half of semicircular rods 22 spaced apart by a cross-rod 23, the grain, &c., on which the head rests having free access through the grill so formed to allow of it being picked up by the scoops 38. The scoop member is rotated from a motor 59 through pinions 57, 56, 52 and an inside toothed wheel 51 bolted to the member 30. Concentrically disposed within the scoop wheel is a fixed chamber 39 having a longitudinal gap 40 in its top line through which the grain, &c. in the risen scoops 36 drops, to be taken in hand by a more quickly rotating screw conveyer 64 disposed longitudinally in the lower part of the chamber 39. The transfer of the material to the chamber 39 is assisted by an air blast entering at 27 and reaching the scoop wheel through ports 29. The conveyer 64, rotated by a pinion 61 from the pinion 56, carries the grain toward the outlet 73, where it is taken up by air under pressure entering at 70 and passing by way of ports 71 to the inside of the hollow shaft 63 of the screw 64 to emerge by ports 72 into the outlet 73. A conduit 11 leads the air and suspended material to a suitable point of discharge.

The tape rollers are driven through a free-wheel device from an oscillating shaft which also, through a belt 20, drives a shaft 22 having gears 21 engaging racks 24 on the carriage 25. Rollers 26 running on fixed rails 27 support the carriage 25. During the reverse movement of the carriage 25, fixed stops 34 cause the sheets to face from the sticks 28 on to the pile. The tapes 1 are of such a length that they can accommodate several delivered sheets so as to facilitate drying of the impressions. Drying-apparatus.-To aid further the drying of the sheets, a series of transverse pipes 29 direct blasts of air downwardly on to the sheets and have a common supply conduit 30. The part of the conduit 30 supplying the pipes 29 situated directly over the pile 8 is cut off the air supply during the return movement of the sticks 28 by a valve 36 connected by links 37, 38 to an arm 39 operated by tappets 40 on the carriage 25.
