[Class 40 (iv)] [Also in Groups XL and XXXVI] Relates to means for modulating and demodulating carrier-waves which are propagated as displacement currents along a dielectric guide line. In Fig. 9, one or more crystals are connected in series with a choke 51 to rectify modulated waves, the extension 52 acting as an aerial or pick-up. Or the crystals may be disposed along a transverse arc of the guide. Or they may be located outside the guide in a cap S as shown in Fig. 12. In Fig. 14, the crystals are arranged radially around a central ring 56, the adjustable pistons 58, 59 providing a balanced impedance coupling between the guide and the two-wire transmission line on the left-hand side of the Figure. Other forms of balanced coupling are also described. The crystals may be replaced by thermo-electric rectifiers. A reflecting piston such as 65, Fig. 22a, may be used in combination with an iris diaphragm 70 which controls the admission of the waves to the " chamber " containing the crystals. Fig. 24 shows a method of heterodyne reception, a local oscillator f2 beating with the incoming signal frequency f 1 to form a standing-wave system in the transverse chamber between two pistons. A valve may be mounted inside the guide as shown and used either as a heterodyne oscillator, as a super regenerator, or to provide ordinary reaction. In Fig. 28, the pick-up wires or " aerials " 97 are connected to transverse Lecher wires 90, which are tuned by bridges 92, 93 and fed with local oscillations from a source 95. The rectifying crystal 94 is bridged across the wires, and feeds a receiving set Glow tubes of the cold-cathode type may also be used as rectifiers. As shown in Fig. 30, one such tube 106, set to a critical state of ionization by the battery 107 modulates the carrier wave from the source 104 by speech or television signals applied at SM. A similar tube 106<1> acts as a demodulator. Or the modulating currents may be applied to field coils surrounding the guide. Fig. 38 shows a multi-electrode valve in which each grid is connected to the wall of the guide by radial conductors 118 which pass through holes in a cylindrical anode 119.

Title: Process for the manufacture of finely divided metal carbonates
Inventor: FRITZSCHE HELMUT RICHARD
IPC: C01G1/00
Filed: 1958-08-08
Abstract: Copper, nickel, and cobalt carbonates having particle sizes within the range 0,002 mm. to 0,20 mm., or mixtures of such carbonates, are prepared by precipitation from an aqueous solution of a copper, nickel, or cobalt salt by an aqueous solution of a carbonate at a temperature within the range 10 DEG  C. to 100 DEG  C., wherein, after or while mixing together the solutions the mixture is either agitated by mechanical means in a closed vessel under the pressure of the generated carbon dioxide, or treated in a closed vessel by introducing gaseous carbon dioxide under pressure, or treated in an open vessel by introducing gaseous carbon dioxide, at a temperature of 10 DEG  C. to 100 DEG  C., the treatment in each case being carried out for up to 20 hours, until the precipitate has attained the desired degree of fineness, the time required being approximately inversely proportional to the pressure.  In a modification, the precipitate initially formed is removed from the mother liquor, if desired washed and dried, suspended, for example in M/50 Na2CO3 solution, and the suspension then treated with carbon dioxide in an open vessel. The carbon dioxide pressure is preferably in the range of 1-12 atmospheres, and is desirably introduced in a very finely distributed form, for example by introducing it through porous materials.  In order to reduce the surface tension and/or viscosity, there may be incorporated up to 70% of an organic solvent, for example ethanol.  The product precipitate may be dried by suspending it in an organic liquid, for example benzene or a homologue thereof, and refluxing the suspension, water being removed from the organic liquid before being returned to the suspension.  The precipitation and treatment can be carried out in the presence of a carrier, for example alumina, pumice stone, kieselguhr, or a silicate.

Title: Improvements relating to the dry-spinning of solutions of polymerised vinyl compounds
IPC: D01D5/04
Filed: 1945-10-04
Abstract: Extruded products such as filaments, threads, fibres, straws, slivers, sheets, strips and ribbons of vinyl polymers are produced by a dryspinning process characterised in that the products carry with them by reason of their movement their evaporative atmosphere in a closed circuit where the atmosphere, after emergence of the said products is subjected to cooling to condense the evaporated solvent or solvents.  The cell should be as free from constrictions as possible in order to maintain the gas-flow.  Any solvent for the vinyl polymer may be used such as carbon disulphide, tetrahydrofuran, glycol formal or acetone.  The evaporative atmosphere may be air, but any other gas may be used, particularly inert gases like nitrogen, carbon dioxide in order to lessen the possibility of fire or explosion.  The spinning solution may contain dyes, pigments, plasticizers, &c., and may be subjected to any textile finishing process.  In a typical example a solution of 30 parts by weight of polyvinyl chloride in 35 parts by weight of carbon disulphide and 35 parts by weight of acetone is heated to 75 DEG  C. and extruded through a 24-hole spinneret into the apparatus described in Specification 605,612.
