Abstract: 162,698. Lees, W., and Moors, W. Nov. 6, 1919. Stationary batch-mixers with reciprocating or oscillating stirrers; batch mixers with circulating devices.-A stirring device for agitating liquids in scouring, bleaching, and dyeing operations, in liming, leaching, and tanning hides, &c., comprises one or more vanes and flaps pivoted to a reciprocating supporting- drum so as to turn from side to side or from top to bottom and vice-versa as the frame moves, stops being provided for limiting the movement of the vanes in either direction against the pressure of the liquid. As shown in Fig. 2, the flaps or vanes t, consisting of boards or plates, are pivoted at their ends u in a paddle or frame b which receives a backward and forward curvilinear motion. The frame is suspended at one end by a pair of links c from studs d at the top of the tank a and the opposite end of the frame supports a shaft g coupled to a link h which is pivoted at its upper end on a shaft i carried by a bracket k. A crank-disc p driven by chain gearing from the driving-shaft s carries a pin o connected by a rod n to a collar or clip m on the link h. The flaps t are free to move about their pivots through about 90, the movements being limited by stops v.

Abstract: 1,086,646. Colour television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. June 29, 1965 [July 2, 1964], No. 27480/65. Heading H4F. A luminance signal EY1/y = (0À59EG + 0À30 E R  + 0À11E B )1/ Y  which is derived from a luminance camera tube 11 and gamma corrector 12 is converted to a luminance signal E y <SP>1</SP> = 0À59E G 1/ γ  + 0À3OE R 1/ γ  + 0À11E B 1/ γ  by the subtraction in matrix 13 of a correction signal #E = 0À52A<SP>2</SP>, where A is the amplitude of a sub-carrier wave E c <SP>1</SP> which is obtained in the customary manner by quadrature phase modulation by E 1 <SP>1</SP> and E<SP>1</SP> Q  signals. The E<SP>1</SP> 1  and E<SP>1</SP> Q  signals are obtained by matrixing colour camera signals E R , E G  and E B  after gamma correction in stages 4, 5 and 6. Filters 8 and 9 restrict the bandwidth of the E 1 <SP>1</SP> and E<SP>1</SP> Q  signals and as a consequence the correction of the luminance signal is only effective over the lower-frequency portion of the signal band. The correction signal #E is derived from the subcarrier wave by an amplitude detector and squaring stage 14. In a second arrangement, Fig. 2 (not shown), the matrix for subtracting the signal #E appears before the gamma correcting stage in the luminance signal channel. More accurate correction of the luminance signal may be achieved by converting the sub-carrier to a form in which the amplitude is independent of phase. This may be done with an elliptical amplifier or by alteration of the composition of the E 1  and E Q  signals. The camera tube 3 for signal E B  may be dispensed with and replaced by a matrix circuit which derives E B  from E Y , E R  and E G .

Title: Improvements relating to alloy steels and to chromised articles made therefrom
Inventor: GLEN JOHN
IPC: C22C38/12
Filed: 1950-11-10
Abstract: An alloy steel, suitable for high temperature applications such as boiler or superheater tubes or steam pipes, has the following composition:- .C.0.03-0.2.per cent, .V.0.05-0.4.per cent, .Mo.0.1 -1.0.per cent, .Mn.0.3 -1.0.per cent, .Ti.0.05-0.5.per cent, .Fe, and the usual impurities, the.. .remainder...  The steel may also contain Si 0.04-0.5 per cent, Al used as a deoxidizer to the ladle in amounts up to 3 lbs./tons of steel and B up to 0.005 per cent.  Articles made of the steel may be given a chromizing treatment.  A treatment described consists in packing articles in a gas-tight retort surrounded with a mixture of pieces of ferro-chromium and sillimanite impregnated with chromous chloride.  A stream of hydrogen is passed through the retort to remove oxygen and the retort is heated in a gas-fired furnace. Hydrogen chloride gas is introduced into the retort for 15 minutes when a temperature of 1080 DEG  C. is reached. The temperature is maintained for 8 hours, then the retort is cooled and the articles removed.  The chromized article may then be coated with aluminium or aluminium paint and heat treated, e.g. by heating to at least 1050 DEG  C. and air cooling or oil or water quenching The cooling may be at a rate controlled to precipitate carbon as carbides in finely dispersed form, further heating to a temperature below the austenitic change point to produce complex carbides containing Ti and cooling at a rate to produce further precipitation of carbides.  The Provisional Specification describes also alloys in which the range of proportions of the constituents are C 0.08-0.3 per cent, V 0.05-0.35 per cent, Mo 0.1-1.0 per cent, Mn 0.3-1.0 per cent with Ti from 1 to 4 times the quantity of C.

Abstract: 895,986. Circuits employing bi-stable magnetic elements. TELEFONAKTIEBOLAGET L.M. ERICSSON. Aug. 17, 1959 [Sept. 2, 1958], No. 28096/59. Class 40 (9). [Also in Group XIX] A shift register, counter or impulse distributer comprises a number of saturable magnetic cores, windings on which are interconnected by bi-stable relaxation circuits which assume working condition only when transferring information from one magnetic core to the next. Associated with each magnetic core M1-M3 is a pair of transistors T1, T2 which are normally blocked. In the case of an impulse counter a core 7-8 on M1 is energized by a starting impulse on contacts K3. M1 is thereby saturated to " 1 " position. Each impulse to be counted causes contacts K1 and K2 to be closed momentarily and in sequence. The impulse at K1 energizes winding 5-6 to saturate M1 to " 0 " position so inducing an impulse in winding 3-4 which renders T2 and therefore T1 conductive in the next stage. In the process T2 takes current from winding 1-2 of the associated core M2 which is therefore set to "1 " position. The impulse at K2 blocks T1 and T2 so that all transistors are now taking minimum current. In the case of a shift register every core has a winding 7-8 for the reception of the desired pattern. The circuit may be used as an impulse distributer with output leads U1.
