Title: Improvements in and relating to the purification and concentration of latex
IPC: C08C1/02
Filed: 1933-12-18
Abstract: 430,426. Latex. RUBBER PRODUCERS RESEARCH ASSOCIATION, 2, Idol Lane, Eastcheap, and STEVENS, H. P., 15, Borough High Street, London Bridge, both in London. Dec. 18, 1933, Nos. 35601/33 and 30496/34. [Class 70] [See also Group III] Rubber latex is purified by removing the carbohydrates, salts and other soluble crystalloid impurities by dialysis with water or with an aqueous solution under such conditions that the normal dilution of the latex is substantially retarded or reversed by hydrostatic pressure exerted on the latex or by the employment on the side of the membrane opposite to the latex of an aqueous solution, e.g. of ammonium soap exerting an osmotic force opposed to that of the latex, or by both these methods. The conditions may be such that the latex is concentrated by the dialysis, or the latex may be concentrated, before or after the dialysis by appropriate treatment, e.g. centrifuging, creaming, or evaporation. Before being dialysed, the latex may be subjected to a treatment promoting a process of hydrolysis of dialysisresistant non-rubber constituents, e.g. by warming, storing with alkali, or addition of a suitable enzyme, whereby such constituents are broken down into dialyzable bodies. Very suitable membranes are vegetable parchment papers of 60-120 gms. per meter weight. Other suitable membranes are gold beaters skin or closely woven cloths which may be padded or treated. with film-forming substances such as cellulose derivatives, rubber or the like. The apparatus shown comprises a number of dialyzer cells each consisting of two membranes 2 mounted on a square frame. A number of cells are clamped or bolted together to form a working unit. Alternate cells 8 are charged with latex and the intermediate cells with water. The water cells contain a woven wire mat 4 or other spacer to prevent collapse under the pressure from the latex. Pipe systems are provided for feeding and discharging latex and water to and from the cells, and the latex pipe system 9 is connected to a source of air pressure whereby the latex cells may be subjected to a pressure of from 1 to 2 lbs. per sq. inch. The dialysis may be accelerated by raising the temperature up to about 50 C.

Title: Improvements in or relating to the preparation of steroid substances
Inventor: ELKS JOSEPH
IPC: H01C10/32
Filed: 1953-12-22
Abstract: 23-Bromo-11b : 12b -epoxytigogenin and 3-esters thereof are prepared from 11a : 23-dibromohecogenin or a 3-ester thereof by reduction (preferably using an alkali metal borohydride or lithium aluminium hydride in a homogeneous medium) to produce a mixture of 11a -Br: 12a -OH and 11a -Br: 12b -OH bromohydrins, and treatment of said bromohydrins with alkali to obtain a mixture of 23-bromo-11b :12b -epoxytigogenin and 23-bromohecogenin, which is then reacted, either before or after esterification of the 3-hydroxyl groups, with Girard reagent T or P, whereby the Girard derivative of 23-bromohecogenin is formed, and the unreacted epoxide is separated from the resulting mixture, preferably by extraction with water, in which only the Girard derivative is soluble.  The 23-bromohecogenin may be recovered from its Girard derivative, by treatment with acid and brominated, if desired after esterification of the 3-hydroxy group, to give 11a :23-dibromohecogenin or a 3-ester thereof, which may then be recycled.  In an example: 11a :23-dibromohecogenin acetate is reduced with sodium borohydride in methylene chloride and methylated spirit, and the crude product refluxed with aqueous methanolic sodium hydroxide solution to give a mixture of 3b -hydroxy - 23 - bromo - 11b :12b  - epoxy - 5a :22a - spirostan and 23 - bromohecogenin, which is treated with Girard "P" reagent.  The Girard derivative is extracted from ethereal solution by washing with water, and acidification to pH<5.0 precipitates 23-bromohecogenin.  Evaporation of the ethereal solution yields the crude hydroxy-epoxide which is acetylated to 3b  - acetoxy - 11b :12b  - epoxy - 5a :22a-spirostan. Acetylation of 23-bromohecogenin followed by bromination gives 11a :23 - dibromohecogenin acetate.  Specifications 759,596, 759,615 and 759,616 are referred to.

Abstract: 1,162,502. Conveyer systems. ALLEN PATENTS Ltd. 10 Aug., 1966 [13 Aug., 1965], No. 35758/66. Heading B7L. Conveyer apparatus comprises a conveyer rail 2, Fig. 3, for a plurality of carriers e.g. skids 23, 23a having depending hooks and an endless driven roller chain 6 disposed in a channel formed between, the vertical side of an angle member 4 whose horizontal side is secured to the bottom of the rail 2 and a vertical member 5 secured to the horizontal side of the member 4, the chain 6 having pivoted thereon a plurality of driving members 12 each having a pulling dog 13 to engage a carrier, e.g. 23, an abutment portion 14 and a control arm 18 provided with a dependent pin 19, each member 12 being urged towards the rail 2, to engage the dog 13 with a carrier, by means of a spring 17 which abuts a pin 16 on the chain. The arrangement is such that when a driving member 12 propelling a carrier, e.g. 23, engages a preceding stationary carrier e.g. 23a through the abutment portion 14, the dog 13 is disengaged from the carrier 23. Spacing between carriers 23 can be determined by dummy carriers (24) secured to the loading bearing carrier by links (25) described with reference to Fig. 1 (not shown). As described with reference to Fig. 2 (not shown) the chain (6) is driven by a wheel (8) adjustably positioned by arms (9) and driven by a motor (11) through a reduction gear (10). Carriers are fed on to the rail (2) from one or more feed-on switches (51) each having a fixed inclined rail (52) and a pivotal head (53) balanced by a weighted lever (57) as described with reference to Figs. 10 and 11 (not shown). To prevent carriers being deposited on to any carrier whilst passing the switch a release guard (56) is engageable by an upstanding arm (21), Fig. 4 (not shown), on the passing driving member (12) to cause release of the carrier being propelled at the time. Similarly carriers are removed from the rail 2 by one or more feed-off switches (39) each having an inclined fixed rail (40) and a manually operable pivotal head (42) as described with reference to Fig. 8 (not shown). Each driving dog 13 has an upstanding part (22), Fig. 4 (not shown), to facilitate the feed-off. Removable release stations (61) disposed around the system each comprise a pivotal ramp (62) engageable by the pin 19 on the control arm 18 to cause the member 12 to pivot and disengage from a carrier 23, as described with reference to Figs. 13 and 14 (not shown). The member 12 may be retained in positive engagement with a carrier e.g. on an incline of the rail 2, by the pin 19 engaging a retaining ramp (60) adjacent the incline, as described with reference to Fig. 12 (not shown). Reference has been directed by the Comptroller to Specification 821,581.

Title: A method of treatment of liquid steel under vacuum
IPC: C21C7/10
Filed: 1968-07-26
Abstract: 1,240,876. Degassing molten steel. SOC. DES ACIERS FINS DE L'EST. July 26, 1968 [July 27, 5967], No.35917/68. Steel is vacuum treated in a ladle 9, when covered by a layer of reducing slag 16, by immersing the lower extremities of 2 vertical refractory pipes 5 and 6. The upper parts of which open into the bottom of an evacuable, vacuum-tight, refractory, heat-insulated chamber 1 of cylindrical vertical cross section. Circulation of the steel is effected up the pipe 6 and down pipe 5 by means of a centripetal electromagnetic force acting towards the centre of the vacuum chamber 1 set up by passing an A. C. current through inductor windings 7 surrounding said chamber and within the metal casing 11. These windings 7 also heat the steel in the vacuum chamber by induction, and are themselves water-cooled, and are supplied with frequencies of 1-20 Hz for providing the circulation only or higher frequencies to act as a heat source. After treatment, the vacuum is removed by introduction of a neutral or reducing gas into the chamber after each vacuum treatment. To aid the setting up of the centripetal force the upward pipe 6 opens out into the bottom of a peripheral channel 10 around the base of chamber 1, the radial width of which is less than the thickness of the induced skin effect currents in the steel. The chamber is heated internally before each treatment by means of a coaxial, graphite ring 13 located inside the chamber and heated by induction by means of winding 14 outside the refractory chamber but within the metal casing 11 supplied with frequencies in the range 150-1500 Hz. Packs of magnetic iron sheets 12 are provided between the metal casing 11 and the windings 7 and 14, to channel the electromagnetic field on the interior of the metal casing but exterior of the refractory chamber and inductor windings. The process is started by sticking diaphragms of thin steel sheet over the lower openings of pipes 5 and 6, evacuating the chamber, and heating it to the required temperature. The vacuum is destroyed by introducing nitrogen or a reducing gas to the chamber and then immersing pipes 5 and 6 into the metal bath in a ladle and evacuating, and supplying current to windings 7. Additives can be introduced via a lock chamber 18, 19, 20. After treatment the vacuum is destroyed with nitrogen or reducing gas

Title: Improvements in or relating to pulse length and pulse repetition frequency discriminating circuit arrangements
Inventor: COOPER ROGER ANTHONY
IPC: G01R29/027
Filed: 1967-08-04
Abstract: 1,219,907. Pulse discriminators. MARCONI CO. Ltd. 16 April, 1968 [4 Aug., 1967], No. 35993/67. Headings H3A and H3T. A pulse length, or frequency, discriminating circuit comprises a cross-coupled transistor bistable circuit with the pulse input connected through a capacitor and unidirectionally conducting device, the capacitor having a leakage path taken to a tap on a potentiometer across the supply. The leading edge of the input pulse applied at IN causes the voltage at the junction of capacitor C1 and diode D2 to rise by a value equal to the difference between the input voltage and the setting of the potentiometer RV1 at P. This voltage then decays exponentially at a rate determined by the values of C1 and resistor R1, and this rate of decay together with the voltage setting of RV1 determine whether, on receipt of the trailing edge of the pulse, sufficient voltage still exists at the fornamed junction to maintain the bi-stable circuit in its prior condition. For resetting, a second unidirectional device and condenser are added in series between the base of the other transistor and a reset terminal. For frequency discriminating this reset terminal is connected to the input IN.
