Patent GB-665263-A (GB)
Title: Methods of treating and transforming chemical substances
IPC: B29C35/08
Filed: 1947-07-31
Abstract: Chemical reactions other than polymerization or condensation of organic thermosetting and thermoplastic materials are promoted by irradiating the reacting components with high speed electrons having a velocity equivalent to more than 1 million volts.  The irradiation should be carried out during one or more short periods lasting less than 10-1 sec.  The reactants may be placed in an electron permeable sealed container and may be heated or cooled, e.g. to -20 DEG  to -80 DEG C.  The reactants may be irradiated with stirring, with or without usual catalysts, e.g. magnesium, cobalt or nickel oxides, in the presence of air or inert gas or in a partial vacuum or under pressure.  The reactants may be treated in the presence of "contact materials" which facilitate reaction during irradiation, but terminate it after irradiation, e.g. oxides of the metals of the second and third groups of the periodic table such as magnesium, zinc, or aluminium.  The reactions mentioned are:-oxidation, e.g. benzoic acid to salicylic acid, halogenation, e.g. preparation of benzyl chloride, benzal chloride, and benzo-trichloride, fluorination and chlorination of benzene; nitration, e.g. of toluene; dehydrogenation of non-drying and semi-drying oils to say linseed and tung oils; refining and bleaching of animal and vegetable oils, e.g. cotton seed oil; hydrogenation of vegetable and animal oils, e.g castor, olive, palm coconut, peanut and cottonseed oils; vulcanization of natural and synthetic rubbers; depolymerization of corn starch; the preparation of butadiene say from ethylene and acetylene, isoprene, 2:3 dimethyl butadiene, 2-chlorobutadiene, styrene, acrylonitrile, vinyl chloride, indigo from indican and indoxyl sulphuric acid, diazo compounds from azo compounds, Vitamin D from ergosterol, colouring matter from phenol, ammonia and condensation products of aniline with ammonia, nitriles, sulphides, inorganic acids, and esters.  The source of radiation and the containers should be of the type described in Specification 673,924. The Specification as open to inspection under Sect. 91 comprises also irradiation with neutrons.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in reels with inertia-responsive arresting means
IPC: B60R22/38
Filed: 1957-07-02
Abstract: 827,105. Spring power-storing apparatus. AEROTHERM CORPORATION. July 2, 1957 [Feb. 1, 1957], No. 20814/57. Class 10. A safety belt of the kind drawn from a spring- loaded spool, comprises means by which excessive draw-out movement is arrested. The belt 64, Fig. 4, is mounted on a spool 2, Fig. 3, within a box 66 and spool pay-out motion, which is anti-clockwise, tensions a returnspring 54. On occurrence of an abnormal payout condition-e.g. an air crash-the spool is stopped by spring-held pawls 36, normally rotatable within a lock-ring 42 fixed to the box, moving outwards to engage the ring. The spool and associated parts, i.e. the ring 42, cam 24 and a plate 30 are rotatably mounted on a bolt 62, Fig. 2, not shown, and the spool flange 8 has raised portions 10, 12, providing between them pawl-location spaces 14, 16. A flange counterbore 18, eccentric to the flange bore 20, mounts an eccentric hub 22 of the cam 24 such that on excessive spool pay-out motion the relative movement between the cam and the plate 30- due to the latter's inertia-causes the cam to force the pawls outwardly to engage the ring 42. When the belt-arresting tension ceases the spring 54 rotates the spool to permit the pawl spring 38 to withdraw the pawls from the ring.

Patent GB-1329492-A (GB)
Title: Capacitor bank for ac networks
IPC: H02J3/18
Filed: 1971-05-19
Abstract: 1329492 Automatic power factor control ALLMANNA SVENSKA ELEKTRISKA AB 19 April 1971 [9 Feb 1970] 21281/71 Heading G3R [Also in Division H2] A capacitor bank, particularly for power factor improvement, has parallel branches each connected to an A.C. network through reverse parallel connected thyristors arranged to conduct in synchronism substantially with the maxima of the network voltage. At part load the banks are connected in sequence so that each bank is held for several cycles at positive or negative maximum voltages, each bank so connected having leakage current replaced at certain maxima. It is stated that the cyclic manner of connection avoids the use and higher cost of D.C. capacitors as A.C. capacitors can be used due to the limited period during which they are held at a voltage maxima. The number of branches fully effective are determined by a means 12, which may be similar to that described in Swedish Patent Specification 314430 and any respective pair of thyristors (A, B) Fig. 1 (not shown) are controlled through separate pairs of AND gates 18, 19 and through signal converter 17, gates 20, 21 which pairs are always in the opposite state. Pulse generator 14 derives from the network series a, b corresponding to parallel maximum positive and negative peaks of a network voltage and which are also applied to gates 20, 21 and through OR gates 34-37 to thyristors A, B. During a period of reserve capacitors are recharged at low frequency e.g. 10-5 c.p.s s controlled by pulse generators 15, 16 in order that leakage current may be replaced as if capacitor voltage falls too far, on reconnection, undesirable transients will ensure. An optional delay member 31 may be inserted to prevent charging pulses during a reserve period being connected as early as point (t<SP>1</SP>) Fig. 2 (not shown). A permutating member (13) Fig. 1 (not shown) in the form of a ring counter may be employed so that in conditions of partial loading the load is distributed cyclically over all the branches, also so that reserve branches are not recharged at the same time. By sufficiently fine division of the capacitor bank corresponding fine control of the capacitance is possible. It is essential that a capacitor branch which is to be made active must have the same polarity as that which it succeeds hence a number of branches must be odd i.e. 2n+1 where n is an integer and the control period of any pulse generator must be (2a+1)x¢ period where a is an integer between O and n. Each thyristor may comprise series and parallel connected thyristors appropriate to the voltage and current conditions.

[Class 87 (ii).] The partly dried body A of a pot is placed on a seating 54d1 in contact with the ends of an appendage such as a spout or handle contained in the plaster mould 54e. The sections of the mould are mounted on supports 54a, 54b slidable on fixed pistons 54h and resiliently held with respect thereto by grooves 54l engaging spring-pressed balls thereon. The supports are actuated to open and close the mould by vacuum or compressed air applied before or behind the pistons 54h through the passages 54m, 54n which register with annular passages in the spotting chuck 62 on which the frame 54d is adapted to seat. During filling, vacuum is applied to the mould through the passages 54m to assist in the extraction of water from the slip in the mould cavity and/or to dissipate air pockets, and, before emptying, the finished and fixed appendage is repelled from the walls of the mould by applying air under pressure. The mould is filled with slip through the nozzle shown in Fig. 3 from a charger device described in Specification 361,360. The nozzle comprises a central tube 99e supplied with slip from the inlet 95e3 via a non-return valve while the excess material is withdrawn through the concentric tube 99c by suction at the outlet 95g2. The nozzle is located on the mould seating 54d1 by a, base 99d in which the outer tube 99c is threaded to be vertically adjustable so that the mould may be filled to any predetermined level.

The printing cylinder of the parent Specification is modified in that the or each roller 8, Fig. 1, has an inverted V-shaped projection 19 and the flexible plate 3 is held in position by springs 20, 21 which are each constrained between a piston 15, connected to the roller 8 by a rod 14, and an inner and wall of an associated cylinder 151, and which exert a radiallyinward force on the roller to thereby clamp and tension the plate 3 through the rails 4, 5. In order to release the plate air is fed through a pipe 22 into the cylinder to overcome the spring pressure and to move the rod 14 towards the peripheral surface of the cylinder 1. The air is introduced into the pipe through the shaft of the cylinder via a supply valve 23 and a handoperated 3-way control cock 24, Fig. 2, which Figure diagrammatically illustrates a fourcylinder press incorporating two plate cylinders of the invention. The valve 23 is so connected to the press control mechanism that during cylinder rotation no air can reach the cock 24, thus preventing inadvertent plate release. Instead of two springs, each roller 8 may have one or more than two.

Title: Urea synthesis process
IPC: C07C273/04
Filed: 1962-06-05
Abstract: In the synthesis of urea from ammonia and carbon dioxide at high pressures the off gases are used to prepare ammonium carbamate solution having a decreased water content which is recycled to the urea synthesis.  The unchanged ammonium carbamate, ammonia and carbon dioxide are adiabatically expanded, and result in decomposition of part of the ammonium carbamate to yield off gases and liquors containing urea, further unchanged ammonium carbamate. The liquors containing the unchanged ammonium carbamate are separated from the gases and then heated to complete the carbamate decomposition, yielding further off gases which are combined with the previous off gases to give ammonium carbamate in a cooler condenser, the solution being recycled under pressure to the urea synthesis.  The process may be repeated on the mother liquors.  Specification 930,213 is referred to.ALSO:In the synthesis of urea from ammonia and carbon dioxide at high pressures, the off gases are used to prepare ammonium carbamate solution having a decreased water content which is recycled to the urea synthesis.
