Abstract: 220,230. Rousseau, G. E. C. Jan. 21, 1924. Roller-and-ring mills. - An ore-crusher comprises a rotating drum containing a crushing- wheel gravitating to the lower side of the drum, with means for feeding ore between the periphery of the wheel and the rim of the drum, and a floating crushing-element between the wheel and the rim at a point opposite the point where the ore is introduced. The floating member may be in the form of a wedge or triangular block. The drum, Figs. 2 and 3, which consists of inner and outer rings 20, 21 and side-discs 29, is supported and guided on rollers 16, 25 carried by shafts mounted in bearings on cement blocks 10, 11, 13.

Abstract: 564,065. Gauges. STAINTON, D. E. Feb. 8, 1943, No. 2043. [Class 106 (ii)] In a gauge comprising a pair of elements having parallel gauging faces and co-operating surfaces inclined to the parallel faces, one of the elements is provided with a regular series of recesses into which abutment means carried by the other element is adapted to engage to hold the elements in longitudinal adjusted relation, the spacing or pitch of the recesses conforming to increments of the nominal height of the gauge. As shown in Figs. 1 and 2, the gauge comprises upper and lower elements 1, 2 with parallel faces 5, 6 and inclined faces 3, 4. The lower element is formed with a central serrated blade 7 which extends into a recess in the upper element: The serrations form a regular series of saw-teeth or may be V-shaped, and a cross-pin 10 or V-ended plunger is located in a slot 11 in the upper element to co-operate with one of the teeth and locate the elements in adjusted position. Instead of a cross-pin, a plunger pin or other releasable means may be employed to hold the elements. As an alternative'to teeth, the blade 7 may be provided with a regular series of holes or recesses and co-operate with spring plungers or balls. The elements 1 and 2 may be held against separation by suitable means such as inserts in the upper element which hold spring blades with tongues to engage grooves in the blade 7. Projections may be formed on one or both sides of the upper element so that the gauge may be turned on its side in use. In a modification, Fig. 7, the blade 20 is separate from the lower element and can be adjusted longitudinally by locking screws 24 threaded in plates 26 on the'lower element. Anti-friction rollers 23 support the blade 20 in a recess in the lower element.

Title: Improvements in or relating to the manufacture of trichloroethylene
IPC: C07C17/25
Filed: 1943-02-08
Abstract: Tetrachlorethane is dissociated by heating into trichlorethylene and hydrochloric acid, in the presence of less than the stoichiometrical amount of a nitrogenous base or a salt thereof.  A high boiling diluent may be present and commercial grades of tetrachlorethane, such as those made by the chlorination of acetylene may be used as starting material.  In examples: (1) a still is charged with tetrachlorethane, triethylamine and a mixture of diphenyl and diphenyloxide as a diluent; on heating, the product is distilled off and condensed and the tetrachlorethane is continuously replenished. The hydrochloric acid is recovered, e.g. by scrubbing with tetrachlorethane to remove traces of trichlorethylene; (2) trichlorethylene is similarly produced without a diluent, quinoline being used as the nitrogenous base.  The following bases and salts are also mentioned: tetraethylammoniumchloride, ethylquinoliniumchloride, tributylamine, trimethylaminehydrochloride, triamylamine, phenylhydrazinehydrochloride, cyclohexyldimethylamine, anilinehydrochloride, piperidine, ethylaminehydrochloride, ditolyguanidine, ammoniumhydrochloride, semicarbazidehydrochloride, naphthylaminehydrochloride and morpholine.

An aqueous explosive composition of improved resistance to separation comprises water, an inorganic oxidizing salt, a thickener, and a partially nitrated aromatic hydrocarbon sensitizer dispersed by an aliphatic monamide having from 1 to 4 carbon atoms. Sensitizers specified are mono- and di-nitroxylene, mono- and dinitrobenzene, mono- and dinitrotoluene, and mixtures thereof. Suitable monamides are formamide, N,N-dimethyl formamide, acetamide, acrylamide, propionamide, and mixtures thereof. The oxidizing salt may be an alkali metal, alkaline earth metal, or ammonium nitrate or perchlorate; ammonium nitrate in combination with sodium nitrate is preferred. Many suitable thickeners are listed and are the same as those given in Specification 1,188,443. A non-explosive carbonaceous fuel may also be incorporated; examples given include finelydivided coal, vegetable products, meals, solid and liquid hydrocarbons, and cellular materials. Pumice, perlite, and vermiculite may be added as cellular mineral materials. The composition may be further stabilized and foamed by the addition of a proteinaceous material, e.g. egg albumin, as described in Specification 1,188,443. In making the composition, the monamide should be added not later than the sensitizer. In examples, the following ingredients are used: aqueous ammonium nitrate liquor, solid ammonium nitrate, sodium nitrate, dinitrotoluene, nitrotoluene, formamide, acetamide, sugar, coal, bagasse pith, egg albumin, and guar gum. Sodium dichromate and potassium antimony tartrate are included as cross-linking agents for the guar gum.

In a means for supporting the bearing caps 8 of a crankshaft of a multi-cylinder reciprocating engine having an open " C " frame 2 and transverse strutting walls 4 arranged on the closed side of the frame, a dilatable compensation screw rod 13 is situated between the cap 8 and the frame 2. Each transverse wall 4 forms a pocket-like cavity 15 which, being open towards the bearing, receives the top end of the rod 13. The bottom end of the rod 13 is engaged in a thrust-socket 14 of the cap 8 and the top end of the rod, being threaded, is screwably engaged in a cylindrical nut 16 pivotally mounted in the wall 4 so that the rod can be swung laterally about an axis 17 into a portion 13a after being disengaged from the cap 8. An abutment surface 18 of the pocket 15 is engageable by the rod 13 when it is screwed further into the nut 16 so as to hold the rod in the swung-out position. The mounting and removal of the cap is further facilitated by the bearing seat 5 being more recessed on the open side of the frame than on the opposite side and by the feet 20 of the cap being symmetrically formed. A spacing member 22 is secured to the frame by a screw 23 and this is removed after the rod 13 has been swung aside. Thus the cap can be removed without withdrawing the struts 9, 10 of the frame.
