Title: A method of producing heat and corrosion resistant aluminium sintered materials
Inventor: THUMMLER FRITZ
IPC: C22C1/04
Filed: 1961-05-30
Abstract: Aluminium-base structural materials are produced from molten alloy containing 5-35% by weight nickel and/or titanium in a total amount of up to 3%, the balance being aluminium, by atomizing the latter in an oxidizing atmosphere to produce a powder containing 1-2% of alumina, treating the resultant powder by wet grinding in an oxidizing atmosphere until the alumina content is in the range 6-15%, and fabricating the powder by conventional powder metallurgical methods. As exemplified, an alloy containing 9% of silicon and 1% of nickel is atomized in an current of air to yield a powder containing 1-2% of alumina and having 80% of its particles in the range 0.06-0.3 mm. diameter. The powder is then ground in vibratory grinders under benzine in the presence of sufficient air to cause the desired oxidation. The bulk density of the powder is increased by grinding in a mill with porcelain balls for 12 hours, and it is then compressed at 5 tons/sq. cm., followed by sintering at 550  DEG C. and 5 tons/sq. cm. The product is then converted to its final form by extrusion at 550  DEG C. and 6 tons/sq. cm.

Title: A method of controlling the firing and quenching of a gas-discharge tube,and a device for carrying out the method
Inventor: LEV LEV NICKOLAEVICH KORAB
IPC: H01J17/04
Filed: 1964-05-12
Abstract: 1,071,551. Gas-filled tube circuits. FIZICHESKY INSTITUTE IM. LEBEDEVA. May 12, 1964, No. 19673/64. Heading H3P. In a circuit for utilizing a cold-cathode gasfilled discharge tube to indicate the conductive state of a semi-conduetor tive state of a semiconductor device, the sensitivity of the tube is increased by supplying it with pulses superimposed on a D.C. bias in addition to the voltage derived from the semi-conductor device. The pulses have a small mark/space ratio and are arranged so that in one state of the semiconductor device the tube will be fired by each pulse only for a relatively short period whilst in the other state of the semi-conductor device, the tube will be fired by the first pulse and remain illuminated until the state of the semiconductor device is restored. As shown, the pulses are derived by resistor 7 and capacitor 8 forming a relaxation oscillator with the trigger/ cathode circuit of the three-electrode coldcathode tube, the voltage from the semiconductor device being applied to terminal 3 in such a way that the anode/cathode gas only breaks down in one state of the semi-conductor device. When the main anode/cathode gas is broken down, the oscillations in the trigger circuit cease so that the circuit may be employed as a keyed sawtooth oscillator. In Fig. 1 (not shown) the pulses are obtained from an external source and fed to the anode of a two-electrode cold-cathode tube, the control voltage from the semi-conductor device being fed to the cathode. An output may be taken from a transformer 4 or resistor in the anode circuit. The circuit is stated to be fired and quenched by a control voltage of 0À1-0À2 volts.

Filed: 1929-06-27
Abstract: 333,016. Imperial Chemical Industries, Ltd., and Wyler, M. June 27, 1929. Phthalein dyes are obtained by condensing in presence of a condensing agent such as sulphuric acid, the aminoxylenol (1-hydroxy-3-amino-2:4. dimethyl benzene) described in Specification 331.687 with a 4-mono- or dialkylamino-2-hydroxybenzophenone-2<1>-carboxylic acid followed by esterification of the free carboxyl group. The acetylaminoxylenol may be used, the acetyl group being removed during the course of the reaction. The dyes give bright pigments when combined with complex inorganic acids such as phosphotungstic. In an example, 4-diethylumino-2- hydroxy-benzophenone-2<1>-carboxylic acid and the above-mentioned aminoxylenol are condensed in presence of sulphuric acid to give a product which dyes tannin-mordanted cotton a bright bluishred. The N-monoethyl or dimethyl bodies may be used in place of the above amino-benzophenone.

Abstract: <PICT:0624366/III/1> <PICT:0624366/III/2> In a ball-point device for applying liquid or paste, a flexible sac retains the liquid in the barrel between one face of the sac and the ball, the other face of the sac being subjected to sustained pressure.  The sac 16 may be made of rubber or synthetic plastic material and, as shown, has its open end attached to a vented plug 17 and is unstressed in its distended condition, but is collapsed when the barrel 14 is charged with liquid. Atmospheric pressure acts upon the dry face of the sac through the vent 19.  In a modification, the open end of the sac is connected to the point end of the barrel, and the sac when unstressed is collapsed and is distended when filled with liquid.  Atmospheric pressure through a vent or spring-pressure is applied to the outside surface of the sac.  The ball 15 is held in a race r with an annular space 281 beneath the ball to which the liquid passes through a port 29.  Any excess liquid carried by the ball past the race r will accumulate in a groove 31 in the tip 10 and be carried back by the ball into the space 281.  The device is filled by removing the tip 10, inserting a tube connected to a container and reaching to the bottom of the barrel, and connecting the vented end of the barrel to a vacuum pump.  According to the Specification as open to inspection under Sect. 91, the sac may be made of nylon.  Further, a spring may be situated within the sac 16, Fig. 1, for applying pressure to the liquid.
