Patent GB-793753-A (GB)
Title: A process for preparing thiamin phosphoric esters
IPC: C07F9/6558
Filed: 1956-06-07
Abstract: Thiaminphosphoric esters are obtained by treating thiamin with a mixture of phosphoric acids, freeing the mixture so-obtained from excess mineral acids by means of basic ion-exchange resin, fractionating the product by means of a column of carboxylic ion exchange resin, concentrating the fractions so-obtained and finally isolating the esters either as free bases or as salts. Prior to treatment with the basic ion exchange resin the phosphorylation mixture may be washed with acetone and then dissolved in water.  The triphosphoric and pyrophosphoric esters are fractionated from the acidic carboxylic ion-exchange resin by water, and subsequently the monophosphoric ester fraction is obtained by means of aqueous orthophosphoric acid.  Dilution of each fraction with acetone and mineral acid permits the isolation of the esters in the form of their salts.  An example describes the preparation of thiamin triphosphoric ester, thiamin pyrophosphoric ester, thiamin orthophosphoric ester chloride and thiamin pyrophosphoric ester chloride.

Title: Improved wing arrangement for rotary wing aircraft
IPC: B64C27/02
Filed: 1936-06-25
Abstract: 477,349. Aircraft having rotarywing systems. ASBOTH HELICOPTERS, Ltd. June 25, 1936, No. 17711. Convention date, April 29. [Class 4] An aircraft includes a rotary wing having an inner-part of zero or small positive or negative angle of incidence and an outer wing part of greater angle of incidence which increases from that of the adjoining inner wing part and again decreases in the outer region of the wing. In one form, the blades are in two parts, the inner part having an incidence for autorotation and the outer part having a positive incidence which increases and subsequently decreases towards the wing tip. The outer portion is cut away near the inner portion to prevent an abrupt change in lift. The incidence of the parts may be manually controlled, e.g. by Bowden cables stops through lever and worm gear. The blade may be continuous may be provided to limit adjustment of blade incidence. The incidence may be adjusted according to the engine torque. In this form, a shaft 42 is driven through springs 44 and is helically threaded to engage a sleeve 47, which can move axially but is prevented from rotating by a key 48. Increase or decrease in engine torque through compression or extension of springs 44 causes the sleeve 47 to move axially and adjust the blade incidence through a bell-crank lever 49. The blade incidence may be adjusted according to winddirection by a vane which may act direct or through servo-motors. It is preferred, that the locus of the centre of lift of the wing sections should lie behind the longitudinal pivotal axis of the blades. In the case of superposed rotary blade systems the two systems may have different characteristics. Specifications 264,965, [Class 4], and 432,124 are referred to.

Abstract: 794,654. Ventilators. GENERAL ELECTRIC CO. June 12, 1956 [June 13, 1955], No. 18121/56. Class 137 A rectangular frame 18 for a ventilating fan 12, and which is readily adjustable to the width of the window in which it is to be mounted, comprises a central section 19 and a pair of end sections 34 movable telescopically in relation to it. The central section comprises a pair of C- shaped rails 24 each of which is cut away along one side at its central portion 28 for the securement at 30, of an orifice ring 22 for the fan 12 the latter being fixed to the ring 22 by means of clips and hangers 32, 33 as described in Specification 794,655, and having a wire guard 16. A central panel 44, preferably made of transparent material, comprises two parts each having an arcuate side 48 for positioning adjacent one side of the ring 22. The two-part panel 44, having lips 46 on its upper and lower edges which engage internally of the rails 24, is retained in grooves 26 of the rails 24 by means of U-shaped springs 54 one of which is disposed adjacent each end of the rails 24 so that an arcuate bend 56 in one leg is sprung into a corresponding opening 52 in the respective end of the associated rail 24, the end of the other leg of the spring being bent over at 58 to engage round the adjacent edge 50 of the two .part panel 44. The arms 38 of the end sections 34 telescope over the rails 24, and each end section supports a panel 42, which is preferably transparent and overlaps the panel 44 in the grooves 26 both panels being urged toward one side of the grooves 26 by the springs 54. In order to avoid inadvertent, complete, removal of the end sections 34 from the central section 19 an opening 60 is formed in a side wall of each end section arm 38 so that, after an end section has been pulled outwards to a point where the openings 60 overlie the openings '52, the bends 56 of the springs 54 snap into the openings 60 and lock the end section to the rails 24. The frame parts can be rigidly secured together, after they have been adjusted to the desired width, by means of set screws 62 which can be tightened in holes 64 until they bite into the rails 24.

Abstract: 274,118. De Forest Phonofilms, Ltd., (Assignees of Forest, L. de). July 10, 1926, [Convention date]. Optical apparatus; records, combined phonographic and kinematographic.-In the production of combined sound and motion picture records, several records of sound from a source such as an orchestra are photographically made simultaneously on the picture film, using a number of microphones located at different points, the subsequent reproduction being effected from all the records acting together, by means of apparatus comprising light-sensitive cells controlling loudspeakers which are placed in positions corresponding to the location of the recording microphones. Fig. 1 shows an arrangement of recording apparatus, comprising two microphones 3, widely spaced but each placed adjacent to a part of the orchestra 1. The microphones, each connected to an amplifier 4 controlling an optical recorder 5, simultaneously produce sound records on opposite margins of the picture film 8. With a different arrangement of the recording-devices 5, the two sound records may be made side by side on one margin of the film, as shown at 17. Fig. 4. The reproducing-apparatus, shown in Fig. 2, comprises a single light source 9 such as a straight filament lamp, associated with two reflecting prisms 10. These direct separate beams through two lens systems 11, whereby the light is passed through the separate sound-records on the film 8 on to photoelectric cells 13. The varying currents in the cells effect reproduction of sound in the ordinary way, by means of amplifiers 15 and loud-speakers 16, the latter being adjacent to the picture screen 20, but spaced apart from each other. The invention as described in the Specification as open to inspection under Sect. 91 (3) (a) is not limited to the recording of sound on motion picture films and reproduction therefrom. Reference has been directed by the Comptroller to Specification 23620/11.
