Title: Improvements in the manufacture and production of dodecahydrotriphenylene
IPC: C07C1/207
Filed: 1934-09-08
Abstract: Dodecahydrotriphenylene is prepared by heating under pressure cyclohexanone or a mixture of cyclohexanone and cyclohexylidene-cyclohexanone with a catalyst capable of splitting off water which contains at least one oxide of a rare earth metal, water-binding substances being added if desired.  As catalysts, mixtures of aluminium oxide with thorium or cerium oxide or both, prepared in the usual way, may be used, and the oxides of the alkaline earth metals are recommended as water-binding materials. The temperature should be between 270 and 320 DEG  C.  A 30--32 per cent yield is obtained.  The process may be made continuous.  In examples: (1) cyclohexanone, a catalyst consisting of 95,5 per cent aluminium oxide and 4,5 per cent thorium oxide, and calcium oxide are heated in a rotary bomb. Water, uncondensed cyclohexanone, and low-boiling products are distilled off under reduced pressure, and the residue is extracted with benzene for the dodecahydrotriphenylene; (2) A similar mixture is heated in a closed vessel to 300 DEG  C. and the product worked up as in example 1; (3) In a continuous process, cyclohexanone vapour mixed with nitrogen is led over the catalyst at 300 DEG  C. and 100 atmospheres pressure.

Title: Improvements in or relating to self-sealing coke oven doors
IPC: C10B25/16
Filed: 1952-10-16
Abstract: 737,580. Coke-oven doors. WARDEN, E. H. Jan. 15, 1954 [Oct. 16, 1952], No. 25928/52. Class 55 (1). Self-sealing coke-oven doors comprising a sealing frame 13 retained upon the edge of the door body 10 by spaced hook-like members 14 have spring means associated with the members 14 to press the frame into close contact with the body and also spring-loaded abutment means engaging the outer edge or face of the frame to press it into gas-tight engagement with the sealing face 26 of the fixed door frame. As shown, the shanks 15 of the hooks 14 slide axially in the reinforcing frame 16 of the door body the pressing action or the sealing frame being produced by nuts 17 acting through a stack of cup springs 18. The shanks may be non circular in section to prevent rotation or a side lug 19 may contact the underside of the door body. By means of a screw 21 which bears against a stack 22 of cup springs a piston 23 within an aperture in the hook is caused to press against the sealing frame, a stem 24 extending through the screw to indicate, when projecting beyond the outer face 25, that distortion of the door frame has rendered readjustment of the screw necessary. In one modification the hooks are rigidly bolted to the door body, the sealing frame being pressed on to-it by a spring- loaded plunger in the nose of the hook. Adjustable pressure is applied to the edge of the frame by a tappet bearing against springs mounted in a bore in the hook and gripped by a fabric friction ring, the tappet being displaced slightly by impact at the outer end. A split tapered metal ring seated in a tapered socket may replace the fabric ring. A further construction comprises a swinging hook which passes through an aperture 36 in the door and has cup springs 18 between an end nut and a block 37 fitting loosely on the shank and bearing at its knife edge 38 on the door face adjacent the aperture. The hook nose bears directly on the side of the sealing frame and is also caused to exert pressure on its outer edge by a spring plunger assembly pivoted to it and regulatable by a screw 44.
