Patent GB-769954-A (GB)
Title: Improvements in or relating to vitamin b antagonist factor
IPC: C07H23/00
Filed: 1955-04-20
Abstract: A vitamin B12 antagonist factor is produced by culturing vitamin B12 nutrient requiring micro-organisms in a growth medium for said micro-organisms in which the growth medium is such as to provide less than "maximal" reproduction of said micro-organisms i.e. the vitamin B12 content of the medium is less than that required to provide maximum growth of the micro-organism.  It is preposed to use a medium in which the propagation rate is half "maximal."  The factor is produced when the requirement of the microorganism for vitamin B12 is increased e.g. when ionic concentration of medium is increased, and this increased vitamin B12 requirement is not satisfied. Ionic concentration is increased by the addition of organic or inorganic ions in isotonic concentration especially inorganic salts e.g. sodium chloride, potassium chloride, potassium sulphate and magnesium chloride.  After incubation the bacteria are separated from the culture broth, and the clarified broth used as such or after dialipis.  The vitamin B12 antagonist factor is non-dialyzable, destroyed by heating to 65 DEG C. for 10 minutes and soluble in 50 per cent aqueous ethyl alcohol.  It inhibits the utilization of vitamin B12 in the biosynthesis of desoxyribonucleic acid.

Title: Processes of pigment-dyeing textile materials
IPC: D06P1/44
Filed: 1948-04-28
Abstract: Textile materials are pretreated with a resin-forming material or with formaldehyde or glyoxal, followed by curing, and are then coloured by means of a pigmented oil-in-water emulsion containing water-insoluble resin.  The pretreatment step may be utilized to procure a crease-resisting, shrinkage-setting or other stabilization of the fabric and may be effected with melamine-formaldehyde resin condensate, urea-formaldehyde resin condensate, ketone-aldehyde resin condensate, formaldehyde or glyoxal.  When applied to fabrics comprising mixed yarns including cotton, viscose, cellulose acetate or nylon fibres, union dyeings are obtained.  Examples are given in which fabrics and yarns, pretreated by one of the methods described above, are coloured by applying various pigmented oil-in-water emulsions.  The Specification as open to inspection under Sect. 91 comprises generally the use after pretreatment of any pigment-resin formulation including dispersions, emulsions and solutions, and includes also an example of the colouring of paper.  This subject-matter does not appear in the Specification as accepted.

[Also in Group XL (c)] A modulator comprises a bridge in which at least one arm includes a non-linear capacitor, to which is applied the modulating signal voltage, the carrier being applied across one diagonal and an inductive output circuit, resonating with the bridge capacitance, being connected across the other. The amplitude modulated output may be demodulated to provide an amplified version of the input signal. The capacitor is of the type having a dielectric of Rochelle salt or titania or its derivatives such as barium titanate either pure or with part of the barium replaced by metals such as strontium and lead. In one embodiment comprising a balanced bridge, giving carrier suppression, each of the four arms of the bridge 20 includes a non-linear capacitor 12 ... 12<SP>111</SP>.

Abstract: 548,522. Supply systems for space discharge apparatus. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Sept. 17, 1941, No. 11911. Convention date, Oct. 10, 1940. [Class 38 (iv)] [Also in Groups XL and XXXVII]  A time delay circuit for use in the starting of a gaseous discharge lamp wherein the electrodes are given a preliminary heating includes in series with the electrodes a cathode glow switch 16 and a thermal switch 17 whose contacts 23, are normally closed. The two switches are mounted in a common casing and a radio frequency condenser 18 is connected across the glow swtich. This consists of an electrode in the form of a bimetallic element 20 carrying electrons emissive material 22, the element 20 moving into contact with the terminal 19 when heated by - a discharge ; the filling is neon argon or helium at 70 to 100 mm pressure. The heating of the element 20 maintains contact in the glow switch until current flow through this switch ceases and the element 20 cools. In the thermal switch 17 one of the elements 24 is a bimetal which is heated by the heater 25 when the starting circuit is closed and a discharge takes place in the glow switch 16 ; the heater 25 is designed to cause opening of the contacts 23 only after sufficient time has elapsed to allow the lamp electrodes to become sufficiently heated. Opening of the contacts 23 produces a transient surge from the ballast inductance to heat down the discharge gap. One of the contacts 23 may be of carbon to replace the heater 25 or the bimetallic element 24 may be used as the heater.

Abstract: 1,128,498. Telegraphy. SIEMENS A.G. 15 March, 1967 [17 March, 1966], No. 12118/67. Heading H4P. A teleprinter exchange comprises receiving stores ES connected to a multiple line KV via units KS which energize a combination of channels in the line KV, and transmitting stores SS connected to line KV via units KE which respond only when a particular combination of channels is pulsed. All the stores are connected via electronic switch units to a multiple line NV, and each change of state within a character signal, or each signal, on line NV is accompanied by a parallel pulse combination on the channels of line KV. In the embodiment described, on reception of data at ES the address passes via the electronic unit and line NV to unit ZVS which, by way of the multiple line KV, selects the unit KE corresponding to the called subscriber. Assuming that unit KS energizes an invariable combination of channels in KV, the selected unit KE is set via line ESV to respond to this combination. Data now passes from store ES, in serial or parallel form, and over line NV to store SS. At the same time KS causes each change in the serial signal or in the parallel signals to energize a combination of channels in KV to which the selected unit KE responds. If the called line is busy the data passes to a store ZS. The exchange is used in multiplex manner, units KS being enabled in succession. The combination to which KE responds may be invariable in which case KS must be set to energize the appropriate combination. Alternatively KE and KS may be fixed, a central unit then converting from one combination to the other.

Abstract: 470,385. Photomechanical printing- surfaces. FEENY, V. F. (Miehle Printing Press & Manufacturing Co.) Feb. 24, 1936, No. 12175/35. [Class 98 (ii)] In a process for producing intaglio printing plates, a positive is made from a continuoustone negative through a half-tone screen spaced from the light sensitive surface at a distance such that minute light dots appear in the light areas on a ground glass screen used for focusing, this positive, in combination with letterpress if desired, is copied on a sensitized metal plate, and the plate is then etched to form ink wells of sufficient depth to allow for the spreading of the ink on the paper during printing. The dots in the areas corresponding to the whites of the original, in the positive may be removed by photographic reduction. In carrying out the process, the original negative is copied on a wet- or dry plate and may be combined with type matter formed by making a press proof of the matter, making a negative therefrom and copying this through a gravure or line screen to form a screened positive. The combined positives are then printed in a vacuum printing frame onto a copper plate coated with bichromated shellac, the borders or other areas to be protected from the etching agent being first painted with a solution of Syrian asphalt in turpentine. The plate is then etched with, e.g. ferric chloride and the resist removed by a cyanide or lye solution. Any necessary local re-etching may then be effected. The resulting plate has wells of uniform depth and of such size in the blacks that the ink spreads during printing giving solid black areas. The process may be used for preparing plates for printing in colours.
