Title: Process for manufacturing minute capsules
IPC: B01J13/10
Filed: 1967-06-29
Abstract: 1,129,430. Making microcapsules. NATIONAL CASH REGISTER CO. 29 June, 1967 [22 July, 1966], No. 29994/67. Heading B8C. Microcapsules are prepared by establishing an agitated coacervatable solution of wallforming polymeric material, dispersing the core material (solid or liquid) therein, and causing the co-acervate phase of wall-forming material to form in the system at a controlled rate which is substantially equal to that at which it deposits on the core material, thereby avoiding the presence of substantial amounts of undeposited coacervate phase and the " clumping " of capsules. The capsules formed are subsequently hardened by conventional procedures, either physical or chemical. Specific examples relate to the encapsulation of a solution of a dye in chlorinated biphenyl, which is dispersed in a gelatin/gum arabic solution at pH 9 to which a solution of polyvinylmethyl ether/maleic anhydride copolymer sodium salt in water/ethylmethylketone and acetic acid is gradually added to induce coacervation. Reference is also made to the encapsulation of various animal, vegetable, mineral and synthetic oils and to pharmaceuticals, e.g. riboflavin, salicylamide, tetracycline HCl, tetracycline phosphate, phenaglycodol, chlorotrianisene, cholesterol, meprobamate, erythromycin propionate, benzathine penicillin G and vitamin K.

Title: Improved manufacture of ammonium chloride
IPC: C01C1/16
Filed: 1929-10-04
Abstract: 333,098. Bronn, J. I., and Concordia- Bergbau Akt.-Ges. Oct. 4, 1929. Ammonium chloride; hydrochloric acid. - Ammonium chloride is prepared by mixing moist hydrochloric acid gas and moist ammonia gas, after superheating to a temperature above 120‹ C. when the solid salt separates from the steam. Disassociation occurs above 200‹ C. but higher temperatures can be used by working at increased pressure, e.g. 270‹ C. at 1“ atmospheres. Mixing of the gases may be produced by propellers, or by using a reaction vessel conprising one or more centrifuges, with porous walls for escape of the steam. Baffles or electrostatically charged conductors may be used to aid the separation of ammonium chloride. The heat of reaction and condensation of the solid salt may be used for superheating the reacting gases. The product, if slightly acid, may be neutralized by addition of ammonium carbonate or bicarbonate. At temperatures of 130-170‹ C. needle shaped crystals of ammonium chloride are produced, and at higher temperatures the crystals tend to become cubic and have a higher specific gravity. Vapours containing hydrochloric acid and about 95 per cent steam, obtained in the process described in Specification 308,028, for preparing hydrochloric acid and nitrates by the action upon chlorides of steam carrying nitric acid vapours or nitrogen oxides, may be superheated and reacted with ammonia. The vapours may contain nitric acid, when the: ammonium chloride produced is mixed with ammonium nitrate. The superheated steam left after the separation of ammonium chloride mav be used again in the production of hydrochloric acid and nitrates.

Patent GB-635902-A (GB)
Title: Improvements in and relating to protective apparatus for polyphase electric systems
IPC: H02H9/08
Filed: 1946-10-16
Abstract: 635,902. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 16, 1946, No. 30841. Convention date, Oct. 16, 1945. [Class 38 (v)] In the protective arrangement of Specification 560,429, the impedance-shorting switch described in Specification 176,191, [Class 38 (v)], is arranged to be reopened a predetermined number of times at set intervals on the occurrence of an open-phase conductor. When the byepass switch 14 is closed on fault, a timer-motor 41 is energized over contacts 60 and timer-contacts 56, 49, 54, 48. A cam 43 quickly permits the contact 48 to engage a contact 53 so that the motor is now energized over normally-closed contacts 69 of a relay 68, and the contacts 53, 48. A parallel circuit is also completed through normally-closed contacts 66 of a relay 63, provided that there is insufficient current through the switch 14 to energize the relay coil 64, such as would be the case if a ground fault had been cleared by the impedance 13, or if there was an open-phase conductor. Shortly afterwards, a contact 47 is moved by a cam 42 with three raised portions to engage a contact 52 and energize an auxiliary relay 59 over contacts 50, 57 and 60. The cam 42 rotates still further so that contact 47 re-engages contact 51 to energize the relay 68 over contacts 61 of the relay 59, contacts 51, 47, locking contact 62, contacts 57, 50 and 60. Contacts 69 thus open and if the fault is a ground fault, coil 64 will be energized and contacts 66 open also, de-energizing the motor 41. If the fault is an open-phase, contacts 66 will be closed and the motor will continue to run. The contacts 67 of relay 63 are closed and a relay 36 is energized over contacts 39, 67, 61, 51, 47, 62, 57, 50 and 60, to energize a winding 34 and open the switch 14. The contacts 39, 60 are therefore opened and relays 36, 59 de-energized, the latter de-energizing the relay 68. The motor 41, however, still runs, since the contacts 53, 48 are still closed. If the open-phase fault still persists, the switch 14 is again closed, and the second raised portion of the cam 42 causes the relays 59 and 36 to begin a second cycle to reopen the switch. This continues for the predetermined number of times, whereupon the switch 14 remains closed, since a cam 45 causes the contact 50 to engage the contact 58 to break the circuit of the coil 36 and also sound an alarm 71. The motor 41 also is cut out by the opening of contacts 48, 53. With a sustained ground fault, the switch 14 closes and remains closed since the coil 64 is energized, so breaking the circuit of the motor 41 at contact 66. As soon as the fault is cleared, the motor 41 restarts and the switch is opened. The Specification as open to inspection under Sect. 91 refers also to U.S.A. Specification 1,537,371. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in the production of oriented films of linear polymers
IPC: B29C55/00
Filed: 1958-09-26
Abstract: A continuous length of film of an orientable, crystallizable linear polymer is stretched in two directions at right angles in the major plane of the film in two steps, the first stretching step being carried out on a continuous length of film while maintaining constant the work of stretching per unit volume of film.  A sample of the stretched film is taken and the level of work per unit volume required to stretch it in the other direction so as to obtain a film having a birefringence of less than 0,03 is determined, before the continuous length of film is stretched in the other direction while maintaining the work of stretching per unit volume of film constant throughout the second stretching at the value determined on the sample.  The test on the film sample may be utilised to determine the level of work in stretching any other continuous length of film of the same type under the same conditions.  The polymer may be a polyethylene terephthalate or a copolymer in which ethylene terephthalate groups preponderate.  The work of stretching may be controlled by thermostatically setting the stretching temperature at the value determined for minimum birefringence.  Stretching may be carried out on cast or extruded film.  Specifications 522,161, 578,079, 718,422, 746,386, 756,597 and 786,176 are referred to.

[Classes 83 (ii) and 83 (iv).] Making road vehicles.-A sheet-metal panel 2 with pre-formed corner holes 4 joined by diagonal slits 5, for motor car bodies &c. is pressed between dies 7, 13 to form a flanged window opening in the panel, the pressing taking place while the work is heated at the corners by gas burners 11 or electrically. The surplus metal 6 is then trimmed off, e.g. by a guillotine. Alternatively the panel may be provided with a pre-formed window &c. opening the same shape as the final opening, but of less size to allow of enough metal to form the flange. The panel is secured on the lower die 7 by a clamping frame 10 before the top die 13 is screwed down by hand. The lower die is provided with corner holes 12 to accommodate the gas burners, each burner consisting of a number of jets, some of which may supply oxygen. Each burner 11 may be mounted so that as the top die moves down it presses down a feeler rod 19 which slides down the burner on a rod 18 so that the heat is applied only where the metal is being worked on as the die 13 advances. The burner may be pivoted to obtain the same movement.
