Title: Process for the preparation of ergotamine, ergotaminine and ergometrine
IPC: C12P17/18
Filed: 1954-04-06
Abstract: Ergotamine, ergotaminine and ergometrine are prepared by saprophytic culture of ergot fungus in vitro in a medium containing zinc and iron ions; the mycelium and solution are then separated and worked up independently by defatting with an organic solvent (e.g. petroleum ether), making alkaline, extracting with a water-immiscible organic solvent (e.g. ether), treating the latter with an acid such as tartaric and obtaining the alkaloids from the acid extract by standard methods.  The preferred concentration of iron in the culture medium is 0.75-12 X 10-5 mol. per litre and of zinc is 1.2-19.2 X 10-5 mol. per litre.  Examples are given of suitable culture media containing various inorganic salts and organic nutrients. Details of the isolation are also given, the tartaric acid extract being treated with alkali and again extracted with ether, ergometrine remaining in the aqueous phase.  The other two alkaloids are separated from one another by percolating a chloroform solution thereof through an alumina column.  The Specification refers to earlier processes for the saprophytic culture of the ergot fungus which yielded crude mixtures or individual alkaloids different from the three of the present invention.  The race of ergot effective in the present invention is that which when growing on rye produces ergotamine, ergometrine and ergosine.

Title: Improvements in and relating to Rontgen-ray and like Apparatus.
Inventor: CAMPION GEORGE GORING
IPC: A61B6/14
Filed: 1918-06-22
Abstract: 122,780. Campion, G. G. June 22, 1918. R÷ntgen-ray apparatus.-Comprises means for indicating the points of entry and exit of the central beam or X-ray of normal incidence into and from the object under treatment. Fig. 1 shows one construction in which a beam A carrying sliding pointers D is pivoted to the X-ray tube box or other suitable part of the apparatus and is arranged so that, when it rests on the upper surface of the box, metallic beads D<1> at the ends of the pointers indicate the position of the normal way. The pointers are moved along the tube until they project on opposite sides of the object, and the X-ray tube is then adjusted until the normal ray follows the desired path through the object. When the adjustment is made, the beam A may 'be turned up out of the way. Fig. 2 shows a modified construction in which the beam A is pivoted to an adjustable sleeve slidably and rotatably mounted on a standard H, which can be set in any position round the circumference of a cylindrical diaphragm E. The apparatus is set up initially by clamping the collar L on the standard so that the sleeve is supported at the correct level with the aid of the screw K for malting fine adjustments if necessary, and by clamping the sleeve in its proper angular position by means of the screw J. Whenset up, the apparatus acts as in the construction previously described.

Title: Production of Fuel Oil from Crude Oils.
Inventor: TINKER FRANK
IPC: C10G7/00
Filed: 1917-07-17
Abstract: 128,288. Tinker, r. July 17, 1917. Hydrocarbons, distilling.- In the production of fuel oils from crude oils, the crude oil is mixed in a chamber a with hot vapour derived from the distillation in a still b of a portion of the treated oil withdrawn from the chamber a. The crude oil enters the top of the tower or chamber a, and there mixes with vapours from the still b. The petrol and other light hydrocarbons escape in the form of vapours through a pipe d. The oil thus " topped " constitutes the improved fuel oil. The larger portion is withdrawn by a pipe c, a small portion flowing to the still b. A portion of the heavier constituents of the crude oil remains as residue in the still b, and is continuously withdrawn therefrom. The partial elimination of the heavier constituents in this manner decreases the viscosity of the fuel oil.
Patent GB-866046-A (GB)
Title: Clutch mechanism for connecting a rotary driving member with a rotary driven member
IPC: F16D41/22
Filed: 1959-03-25
Abstract: 866,046. Ratchet clutches. UNITED AIRCRAFT CORPORATION. March 25, 1959 [April 9, 1958], No. 10329/59. Class 80 (2). [Also in Group XXVII] A ratchet clutch for use in a starter for an aircraft engine is maintained engaged during starting by centrifugal balls rotated by the driving shaft and is subsequently maintained disengaged by centrifugal balls rotated by the driven shaft. An input part 74 of the clutch is connected by spiral splines 78 to a member 68 driven through reduction gearing by a gas turbine starter rotor, and has ratchet teeth 80 engageable with teeth 82 on a driven clutch part 84 which drives the aircraft engine. The clutch is maintained engaged by balls 94 driven by fins 104 on a supporting ring 102 rotating with the driving member 68, the balls co-operating with a cam surface 97 formed on the input clutch part 74. A second set of balls 96 is positioned between fins 114 of a support ring 106 rotating with the driven part of the clutch but axially slidable relative thereto; the balls co-operate with a cam surface 108 on the part 84, outward movement of the balls moving the supporting ring 106 to the left, the ring being connected by a bearing to clutch part 74 and so disengaging it. A light spring 120 engages the clutch when the driving and driven parts are stationary; upon driving the starter turbine both clutch parts are rotated and the balls 94, 96 start to move radially outwardly. The balls 94 are located further from the axis than the balls 96 and so exert a greater axial force on the clutch part 74 than the balls 96 to maintain it engaged. When the aircraft engine starts, flow of gases to the starter is interrupted, and the ratchet teeth 80, 82 disengage. As the part 74 moves out of engagement, the balls 94 are forced inwardly and balls 96 move outwardly, and, due to the greater speed of rotation of the clutch part 84, the balls 96 exert a greater axial force on the clutch part 74 than the balls 94 so that the clutch is positively maintained disengaged. The clutch will also engage during a running start, i.e. when operation of the engine starter is initiated with the aircraft engine rotating at a speed below its starting speed. Under these conditions the clutch parts 74, 84 are disengaged, with balls 96 being rotated and balls 94 stationary. When the starter turbine commences to rotate the balls 94 begin to revolve and are urged outwardly to the position shown in which the balls 94, 96 are substantially equi-distant from the axis. As the starter accelerates the force due to the balls 94 and spring 120 becomes sufficient to engage the clutch. When the aircraft engage is stopped, the clutch is re-engaged by the spring 120, and in order to minimize ratcheting and ensure that re-engagement only occurs at a low engine speed, cam surface 108 is formed with an outer part 112 at an angle of 16 degrees to a radial plane and inner portion 110 at an angle of 45 degrees, cam surface 97 having outer and inner parts 100, 98 at angles of 45 degrees and 16 degrees respectively.

The strip 1 is made of a flexible resilient synthetic material such as polyvinyl chloride, polyethylene or rubber and the strip 2 is either made of this flexible material or is made of a material such as aluminium.

Filed: 1957-04-01
Abstract: Mono- or di-carboxylic acids of polyoxy-ethylene glycols are obtained by oxidation of the polyglycols by means of chromic acid. Preferably alkali chromates and hydrochloric or sulphuric acid are used. Glycols having a m.w. above 600 are preferred but those of lower m.w. may also be treated.
