Title: Improvements in wireless telephony
IPC: H04B1/16
Filed: 1920-07-12
Abstract: 149,011. Huth Ges., Dr. E. F. Dec. 31, 1917. [Convention date]. Vacuum tubes.-A valve transmitter and receiver, particularly applicable for wireless telephony between the various rooms of a building, has its plate circuit and its heating circuit both supplied from the ordinary supply mains. Figs. 1 and 2 show two circuit arrangements. The supply is connected across terminals 5, 6 in the place circuit which also includes an inductance coil and a telephone 9 shunted by a condenser. A condenser 8 is shunted across the supply terminals 5, 6. The filament is connected across the terminals 5, 6 in series with a variable resistance 7. In the modification shown in Fig. 2, the supply is connected at the terminals 17, 18 directly across the plate and filament. In shunt across the plate and filament is an inductance coil 13 with self-capacity and a resistance 19 from which a tap connexion 20 is taken for the filament heating-current. The resistance 19 may form part of the coil 13. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a construction of valve, shown in Figs. 3 and 5 (Cancelled), in which a central tube or rod 23 forming the anode is surrounded by a perforated or meshed grid 26. The cathode 28 comprises a wire stretched to and fro over radial arms 27 projecting from blocks 24 secured at each end of the anode 23. The series resistance in the heating-circuit may be a wire stretched similarly within the valve and of similar section, incandescence being prevented by connecting sections of the wire in parallel; or a wire of larger section may be used. In another arrangement the resistance, which may be of carborundum, is placed in a socket in the valve. Valves designed for a particular voltage have a particular shape of socket and a particular location of the contacts to render them inexchangeable. This subject-matter does not appear in the Specification as accepted.

In a process for purifying an enzyme preparation of L-asparaginase obtained from an L- asparaginase-producing micro-organism belonging to the genus Serratia, wherein said microorganism produces together with the L-asparaginase factors which inactivate the enzymatic activity of L-asparaginase, the inactivating factors are separated from L-asparaginase during some stage of the purification process by salting out with the addition of an inorganic salt, and purified L-asparaginase having an effective anti-tumour activity is recovered. The salt used may be sodium chloride or ammonium sulphate. The solution of crude enzyme may first be treated with manganese ions to remove nucleic acids. The solution may be treated by chromatography on CM-cellulose or DEAE-cellulose before or after the salting-out of inactivating factors.

The following values are preferably maintained, current density 0.7-0.6 amps per sq. dcm., pH value 5.5-7.5, specific conductivity of electrolyte 0.01 ohms<SP>-1</SP>: cms<SP>-1</SP>, bath temperature 60-70‹C. Preferred baths contain not less than 2.5 per cent by weight of sodium citrate and 8-16 per cent by weight of boric acid. A small part of the boric acid content may be replaced by phosphoric acid or arsenic acid. White hard coatings of o.2 mm. thickness or more may be obtained. They may be impregnated or coloured after formation, or colouring matter may be included in the electrolyte bath. The treatment may be applied to unhardened or hardened aluminium alloys containing alloying materials, preferably magnesium and silicon, not exceeding 2.5 per cent by weight; grinding tools, such as discs, may be of such alloys coated according to the invention (see Group XXIII).
