Patent GB-413664-A (GB)
Title: Improvements in electrical machines for welding or heating by resistance
IPC: B23K11/31
Filed: 1934-01-22
Abstract: 413,664. Heating by electricity. SCIAKY, D., 13, Rue Charles-Fourier, Paris. Jan. 22, 1934, No. 2187. Convention date, Jan. 23, 1933. [Class 39 (iii).] In an electric heating machine, the current switch is closed automatically after the desired pressure of the electrodes on the work is attained, by a movable fitment acted upon on the one hand by fluid pressure from the supply reservoir and on the other hand by the fluid pressure in the cylinder in which the piston controlling the movable electrode reciprocates. In Fig. 1, as applied to electric-welding, the movable electrode 1 is connected by links 5 to a piston 4 operated by fluid pressure, such as compressed air, supplied from a reservoir 6 via an expansion valve 7 through a cock 9. The lever 18 which operates the switch 22, 23 or a relay, is controlled by pistons 16, 17 in cylinders 14, 15 respectively connected with the supply and with the lower end of the cylinder 3. During raising of the piston 4 to effect the operative stroke of the electrode, the switch is kept open due to greater pressure in the cylinder 14 than in the cylinder 15 the pressure in the latter of which corresponds to the expansion of the compressed air in the cylinder 3. When the desired pressure of the electrode is attained the pressure is equalized in the cylinders 14, 15 and the switch closes. In a modification, Fig. 4, the cylinder 14 is connected by pipe 13 to the upper end of the cylinder 3, a throttling device is provided at 11 in the pipe 13, and opening of the switch is assisted by a spring 27 or the like. The operative stroke of the electrode is slowed down due to the throttling of the air from the upper end of the cylinder and the switch is kept open by the combined action of the pressure in cylinder 14 and the spring 27 against the action of the pressure in cylinder 15. When the desired welding pressure is reached the cylinder 14 is at atmospheric pressure and cylinder 15 at reservoir pressure and the switch is thus closed. The lever 18 may be replaced by a lever 36, Fig. 7, connected to a double piston 30, 31 in a cylinder connected at one end 34 with the reservoir 6 and at the other end with the operating cylinder. In a further modification the switch rod 39 is carried by a diaphragm 37 dividing an enclosure 38 into two equal parts. In the first two forms the lever 18 may be of T-shape the stem of which operates the switch and the head of which in the first form is provided with rollers engaged by heads on the piston rods, and in the second form is connected by links to the piston rods. The spring may be adjustable.

Filed: 1963-01-17
Abstract: 1,025,061. Granulating fertilizers. CHEMICAL & INDUSTRIAL CORPORATION. Jan. 17, 1963, No. 2209/63. Heading B5A. A process for producing pellets of solid substances, e.g. fertilizers comprises a rotatable drum 2 which at one end receives (a) particulate material via a hopper 8, (b) hot gas from a heater 6, 7 via a conduit 5 and a manifold 3 and (c) a slurry via a spray 27 supplied with gas under pressure. The drum has at its entry end a set of vanes 10 which feed the particulate material to lifting and showering vanes 11 having, intermediate their lengths, dams 12. The volume and temperature of the hot gas and the volume and temperature of the spray are regulated so that the particulate material is first dried in the section of the drum containing the vanes 10, and the droplets of slurry which encase the showering particulate material in the next section of the drum are dried below the agglomeration point. The regulation also ensures that the spray does not penetrate to the end of the drum so that there is a third end section of the drum wherein the formed pellets are dried. The pellets spill over the exit dam 13 and pass from the manifold 14 to the receiving means 15 and then pass on to screening and separating means.

Title: Improvements in textile fibres or yarns of glass and textile materials formed therefrom
IPC: C03C25/26
Filed: 1946-01-23
Abstract: Glass fibres, either before or after being formed into yarns or into woven fabrics, are subjected to chemical etching by means of a weak solution of caustic soda, and thereafter an abrasion-resisting coating material is applied.  The fibres, yarns or fabrics may be dyed or coloured after they have been etched. The dyeing or colouring treatment may precede the coating operation, or a coloured coating composition may be used.  A solution containing about 0.5 per cent of caustic soda may be used as the etching liquid.  The etched fibres, yarns or fabrics may be coated or impregnated by contact with a moistened roller, or by spraying or immersion.  The coating composition may be a solution of a cellulose derivative such as cellulose acetate or viscose, or a solution of a synthetic resin. When the composition has been applied to a glass fabric, the interstices of the fabric may be cleared by brushing or blowing so that the porosity of the material is not impaired.  The glass fibres may be associated with silk, wool or other fibres.

Title: System for transmitting visual information
IPC: A63J5/10
Filed: 1957-01-23
Abstract: 852,815. Television. OPPENHEIMER, J. Jan. 23, 1957 No. 2360/57. Class 40(3). [Also in Groups XV and XX] Prompting information for use by a performer appearing before a television or film camera J, Fig. 6, is derived by means of a television system and reproduced on a cathode-ray tube 1 which is mounted in front of the camera and arranged to project on to an inclined transparent reflector 17 disposed in the path to the camera lens. As illustrated the prompting information is derived from a script 26 wound from roll 27 to 28, the script being illuminated by lamps 25 and viewed by a television camera 22. A monitor cathode-ray tube G is included in the system for use by a  prompter, who is provided with means (not shown) for adjusting the speed at which script 26 is moved and means for inserting additional instructions in the television picture. A typical arrangement is illustrated in Fig. 5 where a panel 29 bearing a number of instructions which may be illuminated by control of individual lamps is provided in the field of view of camera 22 adjacent script 26. A holder 31 in which may be inserted a small card 32 bearing an emergency instruction is also included. One or more further monitors H, Fig. 6, are included in the system for use at suitable points in the studio or on the set. As an alternative or in addition to reproducing the script on cathode-ray tube I, the system may be employed to reproduce material such as pictures or scenes derived from other sources, or even the picture derived from camera J. where this is a television camera. Such arrangements are particularly necessary where the performer needs to co-ordinate his speech or actions with such other material, as for example in the case of a television announcer describing televised film pictures inserted from time to time in a news programme. To ensure that the image reproduced by cathode-ray tube I appears the right way round to the performer, either the horizontal deflection circuit connections to the tube are reversed or an additional reflecting surface is included between the tube and reflector 17. Specifications 15776/45 (open for public inspection), 750,654 and 804,547 are referred to.

Filed: 1964-01-21
Abstract: A gel-forming polysaccharide derivative comprises a finely-divided carboxymethyl ether of starch, amylose or amylopectin cross-linked by esterified carboxymethyl ether linkages. The carboxymethyl ether, in a water-miscible organic liquid medium, is acidified, maintained under acidic conditions until acid carboxymethyl groups in the polysaccharide material form esterified carboxymethyl ether crosslinkages, and then remaining carboxymethyl groups are neutralized.  Specified organic media are methanol, ethanol, isopropanol and acetone.  The cross-linking reaction may be effected by acidification with mineral acids, and maintaining the reaction mixture at e.g. pH 0-2 for a few minutes to several hours, at room temperature.  The acid product may be separated and re-suspended in the above organic liquid medium before neutralization by addition of alkali, or alkali may be added directly to the acid reaction mixture. The neutralized produce may be separated by filtration, washed with the organic liquid medium and dried.  In one embodiment, starch amylose or amylopectin is carboxymethylated in known manner, and the treatment with acid and alkali is carried out on the product without isolating it from the carboxymethylating medium.  The product of the invention, consisting of starch, amylose or amylopectin molecules cross-linked by -O-CH2-COO-groups form stable gels in water.
