Abstract: 1392774 Rotary vacuum filters COAL INDUSTRY (PATENTS) Ltd 13 Feb 1973 6937/ 73 Heading B1D The steam hood surrounding an unsubmerged portion of a partially submerged rotary drum or disc filter is provided with seals to inhibit the loss of steam from the hood. In the drum filter (Figs. 1 and 2) the hood 8 is provided with seals 86 and 87 extending across the drum 4 and seals 80 at the ends of the drum. Seal 86 comprises a replaceable flexible element 88; the seal 87, a pivotable blade 93 which acts as a pressure relief valve; and each seal 80, a flexible blade 81 which slidably contacts an end of the drum 4. The drum 4 is divided into sectors 7. As the drum 4 is rotated in the tank 1 containing e.g. coal slurry, each sector 7 is successively passed through a primary zone where it is subjected to vacuum so that a coal layer is built on the drum, a secondary zone in which suction is applied and in which the coal layer is treated with steam in hood 8, a third zone in which a blast of air is passed through the sector to dislodge coal from the drum and a fourth zone in which the sector re-enters the liquid in the tank and is subjected to atmospheric pressure. Scraper 61 ensures the complete removal of the coal layer. The removed coal is directed into conveyor 59 for discharge e.g. to wagons. The coal layer thickness is controlled by seal 86. The apparatus is provided with means for automatically controlling the supply of steam to hood 8 in dependence on the temperature of the filtrate inside the drum and on the pressure inside the discharge pipe 45, and also the air blasts to the third zone. In the disc filter seals are provided between and around the discs.

Title: Improvements in splash-guards for crankshafts for internal-combustion engines or other machinery
IPC: F16N31/02
Filed: 1932-03-09
Abstract: 398,497. Collecting leakage-oil from bearings. WALTON, T. K., Woodside, Birchwood Road, St. Anne's, and KING- STON, E. G., Clare Street House, both in Bristol. March 9, 1932, No. 7042. [Class 12 (i).] The web 36 of an engine crank shaft has, on the face adjacent a main bearing 24, an outwardly extending knife-edge projection 50 which projects oil escaping from the bearing on to a baffle 51 shielding the cylinder. The projection 50 may be of sheet metal, or integral with the crank-web, or inclined out of a radial plane, and the baffle 51 may have an inturned edge to form a gutter leading oil back to the crank-case. The baffle may be semi-circular or, as shown, it may extend completely round the crank shaft and have drain-holes 53. In the case of a multi-cylinder engine, oil-throwing projections may be formed on the web connecting an adjacent pair of crank-pins, and the baffles may be secured to a bracket depending from the engine casing. In a modification, the oil-throwing knife-edge 65, Fig. 10, is formed by inclining the edge 64 of the web 63, and the baffle 69 is integral with the engine crank case. The baffle 69 may be extended as at 70 so as to catch oil thrown by the big-end 30 of the connecting-rod on its up stroke. Ribs may be formed on the interior of the baffles 69 to assist oil thrown thereon to move towards the end faces of the crank-case.

Title: Improvements in or relating to facing assemblies for friction clutches, bearings, and the like
IPC: F16D69/02
Filed: 1940-04-19
Abstract: 542,578. Friction-clutches; brakes; bearings. WELLMAN CO., S. K. April 19, 1940, No. 7134. Convention date, May 26, 1939. [Class 80 (ii)] [Also in Group XXXIV] In friction-clutches, brakes, and bearings provided with cushioning means the facing member 2 provided with the friction or bearing surface is secured to a support 1 at spaced points 3 and resilient members 7 secured to the member 2 are positioned between the parts 1, 2, intermediate each pair of points 3. The member 2 has recesses 6 to accommodate the members 7 when the latter are compressed so that the facing is fully supported by the member 1. The member 2 may be in segments. As shown in Figs. 1 and 2 for a friction clutch the members 7 are disc-shaped springs, bent cylindrically or spherically and having projections 8 engaging holes 9 in the facing 2. Alternatively the members 7 may be bowed leaf or bent wire springs. The friction member 2 may consist of a metallic backing 5 and a friction layer 4 of sintered powdered metal. The invention may be also applied to cone and band clutches. As applied to a brake the friction facing is in segments, each segment being secured by rivets 36, Fig. 17, to the brake band 30 and a cushion element 38 being positioned at the free end of the segment. If the brake is to run in oil the friction surface has grooves 34, Fig. 16, except at the area 35 immediately adjacent the leading edge of the segment. Thus in operation, when the band 30 is tightened, the leading edge of each segment acts to scrape the oil from the brake drum.

Title: Improvements in quick action electric switches
IPC: H01H17/00
Filed: 1926-03-15
Abstract: 249,517. Veall, A. J. March 17, 1925,. [Convention date]. Snap-action switches; flexible pull actuation.- A switch mounted on a base 1, Fig. 1, secured to a ceiling &c. is operated to "open" and "closed" positions alternately by successive pulls on a cord 30 which is returned to its normal position by a spring. The movable contacts 7 are carried by a U-shaped member 6 pivoted to a bridge 5, the member 6 being connected by a toggle link comprising a rod 14 surrounded by a. spring 19, to a oscillatable lever 16 pivoted at its lower end to the bridge 5. The cord 30 is secured to a spring- returned pulley 25, which upon the cord being pulled, partially rotates a disc 22 mounted coaxial. therewith and driven by a ratchet therefrom. This disc has a pin 21 and slot 20 connection with the lever 16 which is thus oscillated from one extreme position to the other each time the cord is pulled, and thus opens or closes the switch. The stroke of the pulley 25 is limited by a projection 34 thereon engaging a spring abutment 35 on the bridge 6. A projection 36 on the member 6 is engaged by lugs 37 on the lever 16 should the member 6 fail to move under the action of the spring 19, and it is thus moved positively. The switch may be constructed either as a single or as a twoway switch, and the cord may be taken out through a passage 53 instead of through the cover 31. In a modification, the ratchet-driven disc 22 is dispensed with, in which case the cord 30 terminates in a ball chain 45, the other end of which is attached either directly to a spring 44 or to a pivoted lever acted upon by a torsion spring. The balls of the chain bed into depression 46 in the periphery of the pulley 25 when the cord is pulled and thereby rotate the pulley 25 which in this modification carries the pin 21. Upon release of the cord, the balls ride over the periphery, leaving the pulley in the displaced position ready for further operation. Covers.-The cover 31 of the switch is secured to the bridge 6 either by a nut 50, Fig. 1, or by a spring carried bv the bridge and engaging a depression in the cover.
