Abstract: 495,118. Gravity-separation apparatus. HARTLEY, J. W. June 3, 1937, No. 15386. [Class 111] Angularly disposed baffle plates are associated with scrapers which travel over the bottom of a settling-tank so that sludge brought into suspension by the scraper, is directed by the baffle plates towards the sludge outlet. The Figure shows scrapers 12 supported by brackets 11 from an arm 10 which rotates in a circular tank. Inclined or curved baffle plates 18 are fixed to the arm 10. The arm 10 may be supported at the desired level above the tank bottom by rubber or rubber-tyred rollers. Baffles may be attached directly to a scraper of triangular section, sufficiently rigid to render an arm 10 unnecessary.

Patent GB-635631-A (GB)
Title: Improvements in and relating to methods of preparing a monoethyldibenzofuran
IPC: C07D307/91
Filed: 1947-06-11
Abstract: Mono-ethyl dibenzofurans are prepared by reacting dibenzofuran with an ethylating agent in the presence of a Friedel-Crafts catalyst and separating the mono-ethyl dibenzofuran from the reaction product. Generally, the dibenzofuran and catalyst are placed in a pressure-reaction vessel and the ethylating agent added, pressure being employed, if necessary, in order to add the desired quantity of ethylating agent.  For optimum yield, between 1 and 1.5 mols. of ethylating agent are preferably used per mol. of dibenzofuran.  The sealed vessel is slowly heated to 80-90 DEG  C. with agitation and is then allowed to cool.  The resulting mixture contains mono-ethyl dibenzofuran isomers, varying quantities of di-ethyl and more highly substituted dibenzofurans and unchanged material.  The mixture is dissolved in a solvent, for example, trichlorethylene, washed several times, the solvent distilled off and a monoethyl dibenzofuran fraction isolated by fractionation. Suitable catalysts are aluminium chloride or bromide, ferric chloride, zinc chloride, titanium chloride, hydrogen fluoride and boron trifluoride.  Ethylating agents mentioned are ethylene and ethyl chloride or bromide, the ethyl chloride preferably being used in conjunction with aluminium turnings which remove the hydrogen chloride produced.  Examples are given. The mono-ethyl dibenzofurans may be employed in the preparation of vinyl dibenzofurans as described in Specification 635,632.

Title: Improvements connected with internal expanding brakes
IPC: F16D65/14
Filed: 1943-09-21
Abstract: 571,562. Internal expanding brakes. COLEBROOK, W. A., and COLEBROOK, C. A. V. Sept. 21, 1943, No. 15436. [Class 103 (i)] An internal expanding brake comprises a pair of shoes that are slidable rectilinearly for application to the drum by wedge blocks engaging between both pairs of adjacent ends of the shoes and are secured to a rectilinearly slidable member whereby the blocks are moved in the same direction. Adjusting .means for the blocks and shoes is interposed between the slidable member that carries the wedge blocks and the actuating means for that member. The shoes 3 are guided radially by members 14 mounted on the back plate 1 and received in slots in the shoes which are applied by wedge blocks 22, 23 carried by a slidable frame 19 provided with a central opening for the wheel axle 6. The frame is retained against the back plate by bars 28, 29 bolted to that plate and is guided by a projection 30 on the back plate and by the flat-sided extension 33 of a barrel 32 which projects through the backplate. The barrel 32, 33 houses the operating element for the frame 19. This element comprises a slidable rod having a cylindrical part 36 bored to receive the operating rod 40 and its connecting pin 42. The inner part 35 of the rod is notched to form a cam surface upon which rests the ball-end 47 of a two-part screwed-rod 45, 46 connected at its upper end to the frame 19 and disposed between parts 21 of the frame which carry the wedge block 23. Tension applied to the rod 40 thus moves the frame 19 upwardly through the rod 45, 46 to apply the brake: Adjustment of the shoes is effected by varying the effective length of the rod 45, 46. For this purpose the part 46 which screws into the part 45 is formed with a pinion 48 geared to a crown-wheel 49 mounted on the bar 29 and provided with a head 50 by which it may be rotated by a spanner inserted through a hole 51 in the brake drum 2.
