Patent GB-509062-A (GB)
Title: Improvements in or relating to isolation of sterols
IPC: C07J75/00
Filed: 1938-03-03
Abstract: 509,062. Isolating sterols. PARKE, DAVIS, & CO. March 3, 1938, Nos. 6685 and 6686. Convention dates, March 12, 1937, and July 3, 1937. [Class 2 (iii)] A process for obtaining hydroxy ketone compounds from mixtures of non-ketonic steryl alcohols and 3-hydroxy-20-keto compounds of the pregnane and allo-pregnane series not precipitable with digitonin, consists in converting the alcohols in the mixture to a mixture of the corresponding water-soluble acid monoester salts of a dibasic organic acid in a waterimmiscible solvent, dissolving out a purified mixture of the mono-ester salts by means of aqueous liquid, saponifying the purified mixture to obtain hydroxy ketones, reacting the mixture of hydroxy ketones with a ketone reagent and separating the 3-hydroxy-20-keto compounds of the pregnane and allo-pregnane series from the non-ketonic impurities. The starting material may be the carbinol residue from the extraction of phenolic compounds from human pregnancy urine. The ketone reagent may be a hydrazine derivative. Thus, the residue left from 10,000 gallons of human pregnancy urine after the separation of estrin and estriol by the Doisy method is hydrolysed by refluxing with excess of alkali and extracted with ether. The ether-insoluble portion consists of a mixture of pregnanediol and allopregnanediol. The ether-soluble portion is concentrated to give a tarry residue. This is dissolved in benzene and the carbinols present converted to their acid phthalates by adding phthalic anhydride and dry pyridine and heating in a steam bath. The pyridine is removed by washing with dilute sulphuric acid after adding ether. The ether solution is shaken with an aqueous solution of sodium carbonate. The ether layer contains the non-carbinol fraction. The carbonate layer, after thorough extraction with ether, is acidified with sulphuric acid and again extracted with ether. The ether is evaporated and the phthalates saponified by refluxing with alcohol and aqueous potassium hydroxide. Water is added and the alcohol distilled off. The alkaline solution with its suspended solids is extracted with ether to give the carbinols. To these are added ethyl alcohol and betaine hydrazine chloride. The mixture is boiled, poured on ice and extracted with ether. The ether layer contains the non- ketonic carbinols and the aqueous layer the ketonic carbinols. The ketonic fraction is treated with alcohol and semi-carbazide hydrochloride to give the semi-carbazone of epi-allopregnanot - 3 - one - 20. Epi - allo - pregnanol - 3 - one-20 is obtained from the semi-carbazone by treatment with alcohol and sulphuric acid. This may be oxidized by the allo-pregnanedione by chromic oxide and acetic acid. 3-Epi-allopregnanidiol-20 is prepared by treating a solution of epi-allo-pregnanol-3-one-20 with acetic acid and platinic oxide. Acetate or diacetate of epi-allo-pregnanol-3-one-20 is prepared by treatment with acetic anhydride.

Title: Improvements in or relating to aerial systems and to radar systems incorporating thesame
Inventor: RODGERS JOHN
IPC: G01S1/02
Filed: 1961-02-23
Abstract: 980,700. Aerials; radar. MARCONI CO. Ltd. Sept. 16, 1961, No. 6762/61. Headings H4A and H4D. An aerial system for a secondary radar system comprises a passive aerial element having a surface comprised of two outer area portions flanking a smaller central area, the outer portions being adapted to absorb radiation polarized in a predetermined plane, the central portion being unselective, and two plane polarized primary aerials having their planes of polarization mutually perpendicular, one of these planes being parallel to the said predetermined plane. A horn 5, Figs. 2 and 3, containing two mutually perpendicular primary aerials 6 and 7, is directed towards a reflector 1 having the form of an elliptical section of a paraboloid of revolution. The reflector is divided into a plain central area 2 flanked by two side areas 3 (each of twice the width of the central area) whose surface is coated with parallel strips 4 of lossy material spaced # apart (where # is the wavelength at the operating frequency) inclined parallel to the primary aerial 7. Plane polarized waves emitted by the horn 5 due to excitation by the primary aerial 7 are absorbed at the side areas 3 of the reflector and are reflected only by the centre area 2, whereas those due to excitation by the primary aerial 6 are reflected by the whole surface of the reflector. Energization of the two primary elements in this sequence results in a highly directional beam being followed in time by a broad beam. Such sequential beams may be used in an interrogating transmitter of a secondary radar system to obviate false interrogations by transmitter side lobes. This is achieved by providing such a broad suppression beam whose intensity is everywhere slightly above that of the side lobes of such a directional main beam and adapting the transponders in the system to respond to a main beam pulse only if it is received at greater than a predetermined level above the level of the suppression pulses. Such discrimination against main beam side lobes may be enhanced by reducing, in the direction of the principal lobe of the main beam, the intensity of the suppression beam and a transmitter system with this facility embodies a main transmitter 8, Fig. 4, and a suppression transmitter 10 which energize the primary aerials 6 and 7 in sequence by operation of a switch 9. In the position shown the switch 9 connects the main transmitter to the main beam primary aerial 6 and in the alternative position of the switch the suppression transmitter supplies four-fifths of its power in one phase to the suppression beam primary aerial 7 and one-fifth in phase opposition to the aerial 6 so as to reduce the suppression beam intensity in the principal lobe direction. It is stated that a directional lens having said area portions formed on an outer surface may be used as the passive aerial member.

In a water-cooled and moderated nuclear reactor, the rate of flow of coolant through the fuel is controlled by a valve automatically adjusted in accordance with the coolant outlet temperature. Vertical, tubular or rod shaped fuel elements are cooled by the upward passage of steam past them. The super-heated steam flows through vertical tubes, the lengths of which change in correspondence with the steam temperature. Each tube supports a closure member associated with a valve opening, the aperture size of which determines the steam flow. The superheated steam passages are thermally insulated from the water moderator by a layer of stagnant vapour trapped within an internal annular space. In one embodiment, the saturated steam enters the fuel element 10 and emerges superheated at the regulating member 29 which is mounted on the re-entrant component tubes 4<SP>1</SP>, 4<SP>11</SP>, and 4<SP>111</SP>. Tubes 4<SP>1</SP> and 4<SP>111</SP> have a high co-efficient of thermal expansion while 4<SP>11</SP> has a low co-efficient.

Title: An improved method of and apparatus for applying strip material to packages
IPC: B65B51/06
Filed: 1957-03-04
Abstract: 819,509. Applying sealing strips to packages. CHRISTENSSON, O. V. March 4, 1957 [March 13, 1956], No. 7082/57. Class 73 Relates to apparatus for applying sealing strips around three sides of packages fed in succession through the apparatus, the sealing strips being of the kind requiring moistening or coating with adhesive prior to application and the apparatus having no strip-feeding means, the movement of a package causing initial application of the strip to the package and consequent drawing of the strip from a reel. Aocording to the invention the moistening or coating means 33, Fig. 1 and the various strip guide rollers 21, 23, 25, 27, 29 are so arranged that the length of strip between the means 33 and the initial application roller 31 is at least the length required for application around the three sides of a package 10. As shown the apparatus is duplicated on the lower side of a guideway 15 through which the packages are moved by a conveyer 12, sealing strips being applied to the upper and lower sides of the package and around the edges thereof. The application roller 31 is mounted on an arm 35 pivoted on the same axis as the roller 29 and spring-urged towards the advancing packages. Rollers 43, 49 are also arranged in the path of the packages and are carried by spring-urged pivoted arms 41, 47 which are so counter-coupled by chain wheels 39, 45 and chains 51, 53 that rotation of one arm in one sense will cause an equal rotation of the other arm in the opposite sense. In operation the advancing package causes initial application of the strip to the front of the package and then along the upper side as shown in Fig. 3. At this point the package meets the roller 43 which is moved forwardly thus causing rearward movement of the roller 49 to permit passage of the package, the two rollers smoothing down the strip already applied by the roller 31 as shown in Fig. 5. The strip is then cut and on continued advance of the package 10 the trailing end of the strip is applied to the rear edge of the package by the roller 49 as shown in Fig. 7. Fig. 8 shows the apparatus in detail. In order to increase the length of strip between the moistening means 33 and the applying roller 31 in accordance with the package size, the moistening means 33 and roller 23 may be displaced on a support 62. A spring 73 is operated by the leading edge of the package passing through the apparatus to close an electrical contact 74 thus energizing a solenoid 75 to operate a cutting knife 78. The solenoid and knife are connected by a lever and link mechanism 82, 77, 85, 89. At the same time a brake 94 is operated against the roller 21 and the strip thereon.
