Title: Methods of preparing a chemical compound from a charge of its constituents or of treating an already formed chemical compound, which compound in either case includes a volatile constituent
IPC: C22C1/02
Filed: 1966-08-05
Abstract: 1,146,967. Controlling chemical reactions. STANDARD TELEPHONES & CABLES Ltd. 5 Aug., 1966 [11 Aug., 1965], No. 35125/66. Heading B1X. During the preparation of a chemical compound from a charge of its constituents or during the treating of an already formed chemical compound, which compound includes a volatile constituent, by subjecting the charge to a heat cycle in an oven 2, an optimum desired content of the volatile constituent is maintained by adjusting the partial pressure of the volatile constituent in the oven's atmosphere in dependance at the weight of the pilot sample 6 whereby the weight of the sample and hence also of the charge is maintained constant. The sample 6 is suspended by a metallic thread 8 near to one end of the beam 9 of a thermobalance, the other end of the beam making contact when deflected with one of two microcontacts 12, 13 connected to a servo-mechanism 14, which functions to control the regulating mechanism of the flow meter 15. The vapour of the volatile constituent may alternatively be furnished by the thermal decomposition of a chemical compound contained in an auxiliary oven communicating with the main oven, the heating means of the auxiliary oven being controlled by the servo mechanism (Fig. 3, not shown). Particularly applicable to the preparation of ferromagnetic ferrite materials from a charge of a mixture of oxides including ferric oxide Fe 2 O 3  and one or more bivalent metal oxides.

Title: Improvements in and relating to magazine pencils
IPC: B43K21/22
Filed: 1938-12-02
Abstract: 510,132. Pencil holders. GUNTHER WAGNER VERWALTUNGS-GES. Dec. 2, 1938, No. 35191. Convention date, Dec. 20, 1937. [Class 146 (iii)] A magazine pencil holder having a step-by-step feed of the lead comprises a guide tube C to which leads are fed from the magazine and provided with a feed chuck D at its forward end co-operating with a clamping sleeve E by which it is adapted to be connected to a guide chuck G at the front end of the pencil holder so that the two chucks can be retracted together by a spring B. The chuck G is provided with a tubular extension H slidable in the point-section F and carrying a cap L, the base of which is apertured to permit passage of the tube C, but not of the sleeve E. When the tube C is depressed, the sleeve E is carried along until it meets a shoulder N in the extension H, when the chuck D is allowed to open to the extent allowed by the boundaries of a chamber O. The lead is thus fed through the chuck G and through gripping-wires Q located in the chuck and spaced apart a distance slightly less than the diameter of the lead. On the return movement under the influence of the spring B, the chuck D slides over the lead carrying with it the sleeve E until the latter is arrested by the cap L. An opening P is formed in the chamber O to permit removal of broken pieces of lead. According to the Specification as open to inspection under Sect. 91, a projection entering a recess in the casing is formed on the magazine which is attached to the tube C so that the parts cannot be forced out of the casing by the spring B when the chuck D is empty. This subjectmatter does not appear in the Specification as accepted.
Patent GB-481317-A (GB)
Title: New and improved pigment
IPC: C09C1/00
Filed: 1936-12-23
Abstract: A composite pigment comprises a mixture of a base pigment and silica particles, containing more than 2 per cent of silica, said composite pigment having a tinting strength at least substantially equal to that of said base pigment alone, the silica being produced by the calcination of the silicon hydroxide formed by the reaction in aqueous solution of an alkali silicofluoride with ammonia under such conditions that the hydroxide formed has the appearance of a crystalline precipitate. Titania, zinc oxide, zinc sulphide, white lead and lithopone are specified as base pigments, and amounts of silica up to 25 per cent of the composite pigment are mentioned. Silica in the desired form may be obtained by adding ammonium silicofluoride solution to an excess of aqueous ammonia, over a considerable range of temperatures, but if the ammonia is added to the silicofluoride solution, so that an excess of ammonia is not present until the end of the reaction, the temperature must be kept below 34 DEG  C. to avoid the formation of a gelatinous hydroxide. In each case the precipitate is washed, dried and calcined, and the silica so formed has a comparatively high tinting strength and oil absorption, is soft in texture, and its particles are usually of less than 0,5 micron in diameter.  The base pigment and the silicon hydroxide may be coprecipitated, the silicon hydroxides may be precipitated on to particles of the base pigment, or the base pigment may be precipitated on to particles of the silica.  Reference has been directed by the Comptroller to Specification 456,058.

Patent GB-177582-A (GB)
Title: Improvements in and relating to protective devices for electrical power transmissionsystems
IPC: H02H7/08
Filed: 1920-12-18
Abstract: 177,582. Royce, E. M., (Bernard, G. H. B.). Dec. 18, 1920. Protective arrangements for systems of combined generators and motors for transmitting power comprise a self-restoring main currentbreaker closed and held closed electromagnetically, and an overload electromagnetic device which opens a switch in the circuit of the main closing- coil when an overload occurs, the switch being maintained open by a voltage coil wound on the electromagnetic device and connected across the terminals of the circuit-breaker. By this arrangement, the main circuit-breaker, when opened on overload, remains open until the voltage of the generator has been materially reduced. As shown, applied to a Ward-Leonard set for winding purposes, the main circuit-breaker is closed and held closed by the coil 4 energized from the separate source 11 when, as shown, the switch 10 is closed. On overload, the series winding 14 on the electromagnet 13 attracts its armature 12 and opens the switch 10, de-energizing the coil 4 so that the circuit-breaker assumes the off position. The switch 10 is held in the open position by the voltage coil 15 connected across the open terminals 16, 17 and the armature 12 is released, and the switch 10 allowed to close, only when the voltage of the generator has been reduced. An indicating-device may be located in the voltage coil circuit to indicate whether the circuitbreaker is closed or open.

Patent GB-471300-A (GB)
Title: Improvements in electric circuit breakers having arc quenching arrangements
IPC: H01H33/96
Filed: 1936-12-30
Abstract: 471,300. Liquid - blast switches. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Dec. 30, 1936, No. 35757. Convention date, Jan. 2. [Class 38 (v)] A circuit-breaker with extinguishing chambers provided with a differential piston for achieving two oppositely-divided streams in contact with the arc, has the chambers divided into three spaces by two adjacent intermediate walls provided with holes for the passage of the movable contact, one space being bounded by the larger surface of the piston, another by the smaller surface of the piston, and the third being in communication with the space outside the chamber. The cylindrical extinguishing chamber 3 is provided with a cover 6 and contains two concentric cylinders 8, 12 having bases 9, 13 in which are tightlyfitting holes for the movable contact 2. Cylinder 12 is attached to the inturned part 11 of a cylinder 10 secured to cover 6, and cylinder 8 is secured to a cylinder 20 which is fastened to the cover 6 and apertured at 24. A differential piston 21 has a collar co-operating with the cylinder 10 and a collar 23 co-operating with parts 11, 20, and acts, when depressed against the spring 35, to drive gas-free liquid from the space 18 between cylinders 8, 12 across the arc as soon as the openings in bases 9, 13 are uncovered by the contact 2 after it has separated from fixed contact 1. The arc-pressure is communicated initially to the piston through a bore 32 in the contact 2 and through holes 24. The blast flows from space 18 into spaces 17, 16, escaping from the latter through valves 15 if the pressure is adequate. Valves 25 are provided also in the cover 6. In Fig. 2 (not shown), the base 9 is normally pressed against base 13 by means of a spring acting on the cylinder 20, this pressure being overcome when the blast-pressure is adequate. In this form also, valves are located in between the space 18 and the piston. In Fig. 3, the piston is formed by a double cylinder 44, 45 having bases 46, 47, and apertures 48 leading to the upper surface of a collar 49 forming part of the piston. The space between the cylinders 44, 45 leads to holes 42 in the guide cylinder 38 with an inturned part 39. A collar 57 with relief valves 54 is secured to cylinder 38, and a wall 55 is fixed to the support 50 of the fixed contact 1. In breaking circuit, the initial pressure forces the piston downwards to compress the liquid in space 53, and when openings in 46, 47 are uncovered, liquid escapes from that space and from space 56 into the inter-cylincler space, escaping through openings 42.

Title: Absorbent for aqueous physiological liquids and process for the production thereof
IPC: A61L15/28
Filed: 1977-08-26
Abstract: Absorbent fabrics having a high liquid, absorption and retention capacity for aqueous physiological liquids are based on partially crosslinked, especially formalised, cellulose fibres. The cellulose fibres contain 5 to 20% by weight of sodium carboxymethylcellulose in the fibre. The absorbent fabrics are produced by preparing a viscous spinning solution from cellulose xanthogenate by dissolution in aqueous sodium hydroxide solution and allowing the solution to mature. This spinning solution is spun into an acid spin bath, and the filaments produced are cleaned and dried. The method is distinguished in that 5 to 20% by weight of sodium carboxymethylcellulose, based on cellulose contained in the solution, is added to the spinning solution. The filament obtained is cleaned and thereafter partially crosslinked in acid solution. The sodium salt is then reformed.
