[Also in Division B3] A cap of top hat form to be secured, by forcing as by hammering, on the end of a rod or shaft S, e.g. to retain a wheel, has at least one projection 20 on the interior of its wall 40, which acts as a cutter to shave the material of the shaft S to form a bulge 30, and another projection 24 separated from the cutter projection 20 by a recess 32 to act as an abutment against the bulge 30 to prevent removal of the cap. The projection 24 is further from the axis of the cap and shaft than is the cutter 20 so that it does not shave the shaft surface. As shown in Fig. 6, there are pairs of projections 20, 24 arranged around the cap interior and these are produced (see Division B3) by shaving the cap interior and deforming the shavings thus formed into sharp beads. The abutment projections 24 may be formed after the cutter projections 20 or these projections may be formed simultaneously with one tool stroke.

Abstract: 424,976. Photographic sensitive materials. HALDEN & CO., Ltd., J., and HOLDEN, J., Rowsley Works, Reddish, near Stockport. June 6, 1933, No. 16166. [Class 98 (ii)] [See also Group VIII] Photographic printing papers and cloths of the type used in industry such as " blue-prints " are rendered oil-proof by penetrating the material partially or completely with an oilresisting agent before, during or after sensitizing. The agent may be applied to one or both sides and may include insecticides, antiseptics, developing agents or dyes. The penetration may be assisted by the use of wetting agents such as sulphonated lorol, sulphuric esters of fatty alcohols, alkyl naphthalene sulphonic acids, alcohol, or dioxane. As oil proofing agents, colloids, such as casein or gelatin, cellulose esters, chlorinated rubber, or resins e.g. synthetic thermo-setting resins may be used, and hardening agents such as formaldehyde may be used in the case of colloids. Chlornaphthalene derivatives may be used as insecticides and chloramine T as an antiseptic. Examples are given of (1) paper sensitized with a ferroprussiate solution, e.g. that given in Specification 418,369, and treated with a solution of chlorinated rubber in benzene, (2) a diazotype paper treated with a solution of a celluloid varnish diluted with acetone and (3) a diazotype paper to the back of which a solution of casein, ammonia, and formaldehyde in water is applied.

Abstract: 365,002. Liquid controllers. PLANCHE (nee DUMOLIN, M. COTTET-), R., 3, Route de Frans, Villefranche-sur-Saone, France. June 4, 1931, No. 16337. Convention date, June 25, 1930. [Class 38 (iii).] An automatic starting rheostat for an electric motor comprises a casing 1 containing fixed electrodes 4, 5, 6, which are submerged by the upward flow of an electrolyte, the upper portion of the casing 1 being closed by a flexible diaphragm 23 which carries a device 22 for short-circuiting the electrodes when it is forced upwards by the pressure of the electrolyte. With the motor circuit completed, and the liquid level as shown, the motor slowly rotates and in so doing lifts fluid from a lower compartment into the compartment 7 by means of a centrifugal pump 8 driven from its shaft by a belt and pulleys, and as the motor speeds up, the electrodes 4, 5, 6 become more and more immersed. When the liquid level reaches the top of the compartment 7 some of it returns to the lower compartment by means of a channel (not shown), but the pressure in the compartment 7 is increased to raise the diaphragm 23 which by means of a metal plate 22 short-circuits terminals 15, 16, 17 connected with the electrodes, and a state of equilibrium is maintained while the motor runs normally. A valve which restricts the upward movement of the liquid may be employed, and the pump shaft may be vertical and may project from the casing at a point above the upper level of the liquid.

Title: Improvements in or relating to the manufacture of carbon black
Inventor: KING JAMES GRIEVE
IPC: C09C1/50
Filed: 1955-06-07
Abstract: In making carbon black by introducing a gaseous, vaporous, or atomized liquid hydrocarbon material into one end of a cylindrical furnace through a tube which is surrounded by another tube disposed coaxially with respect to the first tube through which a gas is introduced to effect pyrolysis and/or partial combustion of the hydrocarbon material to carbon black, the gas is given an angular swirl by means of a spiral member disposed in the outer tube.  The swirl angle may be 60 degrees and the gas may be free oxygen-containing gas, such as air, or oxygen-enriched, or impoverished, air.  The tubes forming the burner may be directed along the longitudinal axis of the elongated furnace in a conical housing which diverges smoothly into the furnace.  The hydrocarbon tube should extend downstream of the entrance to the diverging portion of the furnace and may be provided with a spiral member to impart swirl.  The hydrocarbon and the air may be preheated to 400 DEG  C. and part of the preheated air may be mixed with the hydrocarbon, or used as atomizing gas therefor.  The ratio of forward velocity of the hydrocarbon to the air is normally unity, but may be increased to 1.5: 1 or more. Additional gas, vapour or atomized liquid hydrocarbon may be injected into the furnace downstream from the flame front through one or several inlets arranged in a geometrical pattern, in a flow direction at right angles to the furnace flow or at an angle pointing downstream.  A fuel gas, e.g. residual or tail gas, may be injected through a second annular passage round the hydrocarbon tube and may be given a swirl by a spiral member.  A water spray or curtain for cooling is provided at the end of the furnace. U.S.A. Specification 22,886 is referred to.
