Abstract: 646,313. Making battery plates; powder metallurgy. ACCUMULATOREN FABRIEK VARTA N. V. May 18, 1948, No. 13448. Convention date, May 17, 1947. [Classes 83 (ii) and 83 (iv)] In a method of making porous metal plates, more particularly for alkaline accumulators, in which powdered metal is sintered on to a grid and a reinforcing gauze, the grid 1 is larger than the finished plate, including the terminal lug and the gauze 2 is larger than the body of the plate, and after a light sintering, the metal powder 3 is pressed, lightly at the central portions and heavily where the powder is over the grid, after which the final sintering takes place and the plate is punched out to the desired shape. Before the final punching operation the plate may be impregnated with an active material such as nickel hydroxide for a positive plate or cadmium oxide hydrate for a negative plate. For a plate of copper powder on a grid of nickelplated iron the second sintering should preferably be at a lower temperature than the first in order to retain the maximum porosity. For plates of nickel powder, however, the second sintering should preferably be at a higher temperature. By using a multiple grid, a number of plates may be produced simultaneously.

Title: Improvements in electrical square-wave generators
IPC: H03K5/13
Filed: 1941-10-23
Abstract: 576,469. Impulse generators. GENERAL ELECTRIC CO., Ltd., and CHERRY, E. C. Oct. 23, 1941, No. 13626. [Class 40 (v)] In a circuit for producing a square wave, a controllable time after the receipt of an impulse, the impulse triggers a first transitron to produce a square wave, the wave being differentiated to produce a pulse, coincident with the termination of the square wave, to trigger a second transitron to produce a second square wave. By varying the value of the coupling condenser between the screen and suppressor grids or the resistance in the suppressor grid lead, the duration of either square wave may be adjusted. A positive impulse,. applied to the control grid of transitron connected valve V1 causes it to generate a negative-going square wave on the screen grid, the duration being controlled by a variable resistance R2. The square wave is differentiated by the short time constant circuit C2, R4 to produce a positive pulse coincident with the termination of the square wave, the negative pulse formed at the commencement being suppressed by diode V3. The positive pulse triggers a second transitron V2 to produce the second square wave, the duration being varied by resistance R2<1>. The second square wave may be differentiated in a similar manner to the first, the resulting pulses triggering further squarewave generators. Specification 511,733 is referred to.

Title: Improvements in or relating to radio beacon transmitters
IPC: G01S1/02
Filed: 1946-05-06
Abstract: 607,023. Radio navigation; valve amplifying and keying circuits. PHILIPS LAMPS, Ltd. May 6, 1946, No. 13675. Convention date, Feb. 18, 1942. [Classes 40 (v), 40 (vi) and 40 (vii)] Relates to means for adjusting the angular position of the equi-signal course line in an overlapping-beam beacon in which the two beams are modulated with different frequencies which are keyed in complementary sequence. According to the invention, the keying periods are approximately equal in duration and the keying is performed at such a frequency, e.g. greater than 50 c/s., that the indicator on a vehicle navigating the course responds to and compares the integrated effect of the two modulation frequencies so that the course is adjusted by adjusting the relative durations of the keying periods. As shown in Fig. 5, the R.F. output from an oscillator 5 is applied through amplifiers 6, 7, modulators 8, 9 and amplifiers 14, 15 to the two crossed loops 16, 17 and modulating frequencies f1 and f2 from the sources 10 and 11 are alternately applied to modulators 8 and 9 through the switched amplifiers 12 and 13. The square-wave output from a multivibrator 18, 19 is applied through an amplifier 25 to render the phase-splitting valve 26 alternately conductive and non- conductive, and batteries 27, 30 and 31 are provided so that the outputs from the anode and cathode of this valve alternately render the amplifiers 13 and 12 conductive and non- conductive. At the mobile receiver, a damped rotary coil indicator is provided which only responds to the integrated effect of the modulation signals so that the position of the effective course line is adjusted by adjusting the time constant of the multi-vibrator circuit. The application of the invention to two- and fourcourse beacons is illustrated in Figs. 4 and I (not shown).

Title: Improvements in or relating to methods of growing quartz crystals
IPC: C01B33/12
Filed: 1953-05-15
Abstract: Quartz crystals are grown from seeds at high temperatures and pressures using flint as nutrient material in an aqueous medium containing sodium carbonate in a concentration of 0.5-3.0 N, sodium hydroxide in a concentration of 0.4-2.0 N, and sodium fluoride in a concentration <PICT:0792724/III/1> of 0.01-0.3 N.  The temperature of the aqueous medium is in the range 320-400 DEG  C and the temperature around the quartz seeds 5-20 DEG  C. lower than that in the neighbourhood of the nutrient material.  The aqueous medium fills from 0.68-0.85 of the free space in the pressure vessel.  The Figure shows an autoclave 1 with cap 2 and sealing ring 4 resting on a hot plate 10 and surrounded by heat insulation 12, 11.  A quantity of flint 16 of such mass and surface area to ensure the required rate of dissolution and growth is placed in the bottom of the autoclave and two Z-cut quartz seeds suspended by platinium wires from a thin steel disc 15 carried by the sealing ring 4.  In examples, growth rates on each growing face about 10.8 mm. in 27 days and about 13 mm. in 25 days on seed crystals 2 X 30 X 30 mm. were obtained.  It is suggested that the presence of traces of aluminium in grown crystals, resulting from the use of flint as nutrient, results in strains and flaws, the constitution of the aqueous medium employed being designed to prevent these imperfections.
