Void [Abridged as open to inspection under Sect. 91 of the Acts, Jan. 21, 1932]. [Class 12 (iii).] A filter arranged in the lubricating system of an internal-combustion engine comprises a fine screen 13, Fig. 2, of star-shaped cross-section mounted within a casing 12 between a fixed partition 14 and a spring- pressed partition 15. Oil entering the casing at 9 passes into the interior of the screen through apertures in the partition 15 and normally passes through the screen to an outlet 9a. If the oil is cold so that the pressure within the screen rises above a predetermined amount, a spring-loaded disc valve 18 normally closing apertures in the partition 14 opens, whereby the oil passes to an outlet 23 without passing through the screen. A tube 20 adapted to receive a thermometer is arranged within the casing. Oil is supplied to the inlet 9 from the engine sump 6, Fig. 1, by a pump 8, and the outlet 9a leads through a cooler 11 to a tank 1 whence oil is supplied to the engine parts by a pump 2. The outlet 23 leads to the suction side of the pump 2, whereby when the oil is cold the screen, cooler, and tank are byepassed. In a modification, the partition 14 is dispensed with, the valve 18, Fig. 4, serves normally to close the lower end of the fine screen 13, a coarser screen 24 surrounds the screen 13, and the outlet 23 is closed. Oil entering at 9 normally passes through the two screens in series to the outlet 9a, but when the oil is cold the valve 18 opens to byepass the screen 13.

Title: Improvements in and relating to the polymerisation of olefines
Inventor: TAYLOR ARTHUR WILLIAM CHARLES
IPC: C08F2/00
Filed: 1956-11-29
Abstract: Alpha-olefins are polymerized in the liquid phase and without the addition of more than small amounts of an inert diluent, the liquid phase being maintained at a temperature close to its boiling point under the operating pressure, using as catalyst the material formed by reacting an organo-compound of a non-transition metal of Groups I, II or III with a compound of a transition metal of Groups IV, V and VI.  Vaporized olefin is preferably reliquified by means of a reflux condenser and returned to the reaction zone in a continuously operated process.  A slurry of polymer in liquid olefin is continuously removed from the reaction zone, the liquid olefin separated from the polymer and returned to the reaction zone.  The rate of polymerization is controlled by adjusting the rate of addition of the organo-metal compound and/or the transition metal compound in accordance with the rate of vaporization of the olefin. The two catalyst components may be introduced separately into the reaction zone. Specified olefins are propylene and butene to which may contain some ethylene and their copolymers.

Abstract: 852,750. Cathode materials and processing. TELEFUNKEN G.m.b.H. Nov. 27, 1957 [Dec. 17, 1956], No. 36991/57. Class 39(1). Method of manufacturing discharge valves including a cathode which has a cathode carrier incorporating an activating agent and supporting an oxide layer which is not air-resistant, comprises the steps of applying to the cathode carrier an air-resistant compound (e.g. nitrates or carbonates of alkaline earth metals such as barium or strontium), exhausting the valve envelope and at the same time thermally converting the applied compound into the oxide, sealing the valve envelope and thereafter activating the oxide layer by bringing the cathode carrier and the oxide layer to a high temperature, the gas formed during the conversion being, for its substantial removal, diluted with a gas or gases that do not react with the activated oxide layer. The valve can be scavenged several times with the diluting gas or gases. The diluting gas can be nitrogen or hydrogen or can be formed from one or more thermally decomposable compounds, such as hydrides or nitrides, which are introduced into the valve, and heated. Zirconium hydride can be used which yields the getter zirconium after decomposition. The cathode carrier can be a nickel sleeve incorporating magnesium as activating agent. The manufacture of the valves can be supervised by mixing with the starting material producing the oxide layer a radioactive component, e.g. C 14 , of an element or compound which is contained in the produced gas after thermal decomposition of the starting material and testing the anode for radioactivity.
