Title: Improvements in and relating to thermionic valve amplifying arrangements
IPC: H03F1/33
Filed: 1925-10-23
Abstract: 264,910. Graham, M., and Graham, A., (Representatives of Graham, E. A.), and Paddle, L. H. Oct, 23, 1925. Transformers. - The inter-valve couplings of low - frequency amplifiers comprise a transformer or auto-transformer 2, Fig. 2, with the primary coil or section shunted by a resistance 5 and a secondary coil or section connected through a condenser 8 to the grid of the next valve. The grid circuit of this valve includes a. biasing resistance 12 and may also include a choke coil 13 and a batterv 11<a>. The condenser 8 may be connected to the upper end of the coil 2, or may be adjustably connected by tappings 15 as shown. Alternatively a potentiometer resistance may be shunted across the coil 2 and the condenser 8 connected to the movable slider. The resistance 5 prevents distortion by equalizing the impedance of the output circuit of the valve for different frequencies. The choke 13 offers high impedance at voice frequencies, and prevents the condenser 8 and resistance 12 from shunting the transformer. Fig. 4 shows a constructional unit comprising the transformer winding 2 and core 20 with the condenser 8, resistances 5, 12, and choke coil 13 supported thereon by brackets. The unit may be enclosed in a metallic casing provided with terminals.

Abstract: 537,467. Matting textiles. SOC. OF CHEMICAL INDUSTRY IN BASLE. Sept. 26, 1939, Nos. 26668 and 26669. Convention dates, Sept. 30, 1938 and Aug. 18, 1939. Samples furnished. [Class 15 (ii)] In the process of matting textile materials by immersing them in a bath containing urea and formaldehyde or a condensation product thereof in solution with a condensing agent (e.g. acid), such as described in Specifications 469,688 and 528,686, the bath is used repeatedly with fresh batches of textile material by adding further quantities of reagent to replace those consumed. The higher the concentration of urea-formaldehyde compound, the lower the hydrogen ion concentration of the acid should be. It is advantageous to work with a proportion of 1 part of goods to be treated to at least 15 parts of liquor. In an example, 1 kilo of viscose artificial silk is reeled for 1 hour at 20 C. in 80 litres of liquor containing .32 kilo of urea, .48 litres of formaldehyde solution containing 360 grms. of formaldehyde per litre, and 1.4 litres of HCl of 30 per cent. strength. For matting a further kilo of viscose in the same bath, the liquor receives .1 kilo of urea and .16 litres of formaldehyde. In other examples a solution of monomethylourea is used. Samples of matted viscose artificial silk yarn are furnished produced by a solution of equimolecular proportions of mono- and di-methylol urea and by a solution of di-methylol urea, respectively.

Abstract: 497,868. Vehicle and like suspensions ; hydraulic springs. MORGAN, J. W., and PAYKEL, H. Oct. 5, 1937, No. 26923. Convention date, Oct. 17, 1936. [Classes 108 (ii) and 108 (iii)] In a hydraulic stabilizing or equalizing device for supporting a vehicle chassis or other body upon the axles or other support, a number of pairs of cylinders fitted with opposed pistons are interconnected in series so that movement of one or more of the pistons is transmitted to the remainder, the arrangement preferably being associated with metallic, pneumatic or other springs or cushioning devices which take the load of the supported body. As shown diagrammatically in Figs. 1-3, the rectangular body 2 is supported by means of helical springs 2a with each of which is associated a cylinder 4 fitted with a pair of opposed pistons 5, which in turn are linked to a rocker arm 8 on a shaft 9 connected by an arm 10 and link 11 to the base 1 . Two corresponding ends of the cylinders on the same side of the body 2 are interconnected by pipes 6, while the remaining ends of diagonally opposed cylinders are connected by pipes 7. Any movement of one or more of the pistons due to uneven loading is hydraulically transmitted to produce a coordinate movement of the other pistons. In applying the invention to the suspension of a motor vehicle chassis, each stabilizing cylinder 4, Fig. 6, may be associated with a similar cylinder 12 fitted with opposed pistons 15 and serving as a load-supporting and vibrationdamping means. The pistons 5 and 15 are linked to a common double-armed rocking member 8 mounted on a shaft 9 having an arm 17 which is connected to the vehicle axle. Alternatively, the cylinders 4, 12 may be mounted on the axle and the arms 17 be connected to the chassis. In the cylinders 12 the enclosed spaces contain oil or like medium acting through perforated plates 22 upon resilient cushions 23 preferably comprising balls of rubber which are inflated with air to various degrees of pressure, while all the spaces may be connected to a common auxiliary chamber fitted with pressure-varying means. In addition, a control valve 25, Fig. 9, may be fitted in the pipe lines 20, 21 between the various cylinders so as to provide for synchronized movement of the pistons in all the cylinders, or for synchronized movement of the front or rear pistons and independent movement of the remaining pistons, or for independent movement of all the pistons.

Title: Improvements in or relating to a process for melting compounds without substantial decomposition
IPC: C30B13/00
Filed: 1954-09-17
Abstract: In the treatment of indium arsenide to produce a semi-conductor the compound is melted in a chamber the coldest point of which is maintained at a temperature between the melting point of the compound, i.e. circa 936 DEG  C., and the condensation temperature of arsenic (the most volatile constituent) i.e. circa 485 DEG  C.  Part of the compound itself or the crucible or the like used for melting the compound may be at the coolest point.  The condensation temperature depends to some extent on the surface at the coldest point, i.e. it will be lower when the surface does not facilitate the formation of <PICT:0781727/III/1> <PICT:0781727/III/2> nuclei, e.g. when using very pure quartz, and higher when an affinity exists between the surface and the vapour.  The chamber may be sealed (Fig. 1, not shown) or may be provided with a throttling member D which may be at the lowest temperature in the chamber (Fig. 4) or at a higher temperature (Fig. 5).  Zone melting, drawing of crystals from a melt, or melting followed by ordinary recrystallization, may be carried out in the chamber.
