Filed: 1923-12-03
Abstract: 207,827. Ges. f³r Drahtlose Telegraphie. Dec. 2, 1922, [Convention date]. Combined transmitting and receiving arrangements; thermionic amplifiers, detectors, and generators.-In a two-way telephony system an aperiodic valve generator C<1> at the one station B is energized by the carrier wave radiated from the distant station A, the valve generator C of which is associated with a definitely tuned circuit D. This renders it unnecessary to provide positive means for maintaining a strict constancy of wave-length as the generator C' is automatically kept, in step with the frequency of the circuit D. The incoming carrier wave at the station B impulses the local generator through the coupling G, F. Corresponding high-frequency oscillations are fed to the aerial through the coupling J, H. These are modulated through a transformer E1 and are received in the telephone K at the distant station A. Modulated signals from the station A are in turn received in the telephones K1 at the station B. The method is applicable to wired wireless systems. An amplifier may he inserted between the coils G and F, or, as shown in Fig. 4, a tuned circuit M may be interposed between the aperiodic grid and plate circuits of the valve C1.

Patent GB-311774-A (GB)
Abstract: 311,774. Telefonaktiebolaget L. M. Ericsson, (Assignees of Sieverts Fabriks Aktiebolag, M.). May 16, 1928, [Convention date]. Cables; arrangement and disposition of parts of; with pressure controlling means for oil filling; laying; armouring. - In order to prevent the formation of voids in a leadsheathed high-tension cable, the insulating material is placed under pressure, and the lead sheath is covered with cement or concrete which may be reinforced, or is enclosed in tubes. In the construction shown in Fig. 1, a central oil cavity is formed in a conductor 1 which is covered with oil-impregnated paper insulation 2. A lead sheath 3 surrounds the insulation 2 and is enclosed in a layer 4 of impregnated fabric or paper. The cable thus formed is cast into concrete which forms a covering 5. Armouring 6, preferably helical wire concentrically disposed in the covering 5 is provided. When cables are laid out side by side, they may be cast in the same concrete, which may be of triangular section. In a modified construction, the outer covering is formed by a metal tube of steel, copper or brass, applied over the lead sheath of a rubber-insulated cable. Fig. 5 shows a method of laying down the cable, which is preferably divided into hermetically sealed sections 13, 14, the sections being united by sleeves 15. 'The cable ends may be mounted on poles 16, 17 and formed with end sleeves 18, 19 from which the conductor projects through insulators 20, 21. Fig. 6 shows a cable 22 formed with an expansion reservoir 23 communicating through a junction box 24 with the cable interior. A bottle 25 containing highpressure gas such as carbon dioxide is connected to the reservoir 23 to maintain the pressure. The bottle 25 may be cut off by a cock 26, and used only occasionally to compensate for leakage from the reservoir 23. In a modified apparatus, constant pressure is maintained within the cable by a pump which is adapted to pump oil from a reservoir into the cable through an end box when the cable is cooling. When the cable is heated, the oil is allowed to pass back to the reservoir through an automatic valve. The pump may be operated automatically under control of the pressure in the cable. The Specification as open to inspection under Sect. 91 (3) (a) describes also a rubber-insulated cable having metal tubes disposed directly on the insulation. This subject-matter does not appear in the Specification as accepted.

Title: Stabilized ú¯-vinyl pyrrole compounds and process of producing the same
IPC: C07D207/323
Filed: 1945-11-20
Abstract: An N-vinyl pyrrole composition stabilized towards polymerization at temperatures below 100 DEG  C. but above its melting point contains up to 1 per cent of morpholine.  Specified N-vinyl pyrrole compounds are N-vinyl pyrrole, carbazole, tetrahydrocarbazole, propyl carbazole, indole and naphthocarbazole.  At slightly higher temperatures, e.g. 120 DEG  C., the inhibitory effect is sufficiently reduced so that complete polymerization of the N-vinyl pyrrole may be effected by heat. The morpholine may be added by mixing or by addition to a solution of the monomer in methylene dichloride or cyclohexane followed by evaporation of the solvent.  Porous materials may be impregnated with the composition at a temperature slightly above the melting point of the monomer, and then heated in order to polymerize the N-vinyl pyrrole compound in situ.  The presence of morpholine has no adverse effect on the electrical properties of the polymer formed.

Title: Improvements in or relating to magnetisable iron oxides
Inventor: SOBY WILLIAM
IPC: G11B5/706
Filed: 1953-11-12
Abstract: A magnetizable iron oxide suitable for use in magnetic recording media is produced by heating an intimate mixture of finely divided ferrous oxide and finely divided a-ferric oxide in a substantially neutral atmosphere.  In the preferred process which is described in detail, a nonhydrated acicular a-ferric oxide preferably having a maximum particle size of one micron is suspended in a solution of ferrous sulphate at 60 DEG C. and an ammonium oxalate solution also at 60 DEG C. is added thereto.  After filtration and washing the solids are dried at 100 DEG C., ground and heated in a nitrogen atmosphere at 375 to 525 DEG C., e.g. 400 DEG C. in a heated rotatable tube to form black ferroso-ferric oxide.  This product preferably contains 10-65 per cent of ferrous oxide. Thereafter the temperature may be allowed to fall to 200 DEG C. and nitrogen replaced by air to obtain g -ferric oxide.  The temperature should not rise above 450 DEG C. in this process.  The g -ferric oxide retains the acicular form of the original ferric oxide.  The products may be dispersed in a ball mill with a binder such as polyvinyl chloride or copolymer resin with plasticizers and solvents for use in magnetic recording media.  Reference has been directed by the Comptroller to Specification 648,494.
