Filed: 1939-04-22
Abstract: 581,320. Fluid-pressure brakes. SCHNEIDER, T. April 22, 1939, No. 12171. Convention date, Dec. 16, 1938. [Class 103 (i)] [Also in Group XXIX] A device for cutting off a defective pipe line of hydraulic braking systems or other pressure systems in case of leakage comprises a piston 8 having a passage through which liquid passes between the passage 21 connected to for instance a master cylinder and the passages 4, 5 connected to pipe lines leading to brakes. In the case of leakage in one of the brake connections, the fall of pressure therein causes a ball valve 10 in the piston 8 normally held open by spring 11 to close the passage through the piston when the brakes are applied and the piston 8 is forced down and closes the valve 12 to cut off the connections 4, 5. The valve 12 is held in its two positions by a friction sleeve 31 and by an elastic ring 14, which in the position shown, is retained in a groove, but may be forced off, on to the tapered part 22. A passage 23 is provided for filling the system, and may contain a ball valve 25 which seats under the same conditions as the ball 10. The stem 13 of the valve may, on descending, close the circuit of an indicator lamp.

Title: Improvements in or relating to grinding mills
IPC: B02C17/00
Filed: 1958-04-24
Abstract: 856,066. Grinding mills. INSINOORITOIMISTO - ENGINEERING BUREAU R.T. HUKKI. April 24, .1958 [April 27, 1957; Nov. 27, 1957; Feb. 5, 1958], No. 13023/58. Class 59 A method of grinding in a ball, rod, tube or like mill comprises rotating the mill at a super-critical speed such that the said speed, when co-related with characteristics of the tumbling load, results in a sub-critical speed of the said load, the critical speed being defined by the formula nc = #<SP>76.6</SP> D-d  where nc is the numerical value of the critical speed in revolutions of the mill per minute, D the internal diameter of the mill in feet and d the mean diameter in feet of the articles comprising the tumbling load. It is stated that with the above method a zone of attrition grinding is formed, as shown shaded in the Fig., between the mill lining and the outer layer of the tumbling load, provided that the mill has a comparatively smooth lining. The mill shell may be provided on the inner periphery thereof with holding bars or other obstacles so that the mill forms a lining during use with a layer or layers of the tumbling load, the attrition grinding in this case-being based on the speed difference between the layer or layers of grinding material adjacent the mill shell and the layer or layers of the tumbling load adjacent to them. The attrition grinding may be achieved by adjusting the speed of rotation of the mill to the desired value by an alteration of the load e.g. an alteration in the mass of the individual particles comprising the load or an alteration in friction between the load and the internal surface of the mill. The alteration in friction may be achieved by finely grinding or pulping the material to be ground or by adjusting the amount, whether by way of mass or weight, of the material to be ground within the mill. The friction may, however, be altered by a change in the fineness of the material to be ground or by providing a grinding media which has a higher specific gravity than the average specific gravity of the material to be ground or of the material from which it has been separated. Various examples are given of the grinding material to be used. The invention is stated to be applicable to autogenous methods of grinding i.e. where the material to be ground and the grinding media mixed therewith consist of the same solid substance.
