Patent GB-606151-A (GB)
Title: Improvements relating to blading of turbines, compressors and like machines
IPC: F01D5/30
Filed: 1945-12-21
Abstract: 606,151. Turbine blades. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., FIELDEN, G. B. R., and OGSTON, W. M. Dec. 21, 1945, No. 34827. [Class 110 (iii)] An axial flow turbine blade of the kind in which the centre of gravity of the blade is offset from the radial direction so that the bending moment on the blade due to centrifugal force balances that due to the gases acting on the blade, is mounted individually and independently so that it can tilt under the influence of both these forces so as to accommodate any changes in the relation between the values of them. The turbine blade 3, Fig. 1, is pivotally mounted through needle roller bearings 5 on axially extending pins 6, the ends of which are held in recesses in the flanges 2 of a rotor disc 1 which are held together axially under tension. A peripheral clearance is left between adjacent blades to allow them to tilt. As the roller bearings 5 tend to bend under load, the centre portion of the bore may be relieved as at 7 to allow the pin to bend freely. The pins 6 may be skewed with reference to the axial plane. In a modification, the blade is attached to the rotor by flexible radial strips, the ends of which are bent around pins, one of which is within the body of the blade root and the other held between two adjacent rotor discs. In a further modification, Fig. 7, the blade is able to tilt in more than one plane. Attached to the root of the blade is a part-spherical head 11 which co-operates with members 14 to form a partspherical ball-race 15. This arrangement allows the blades to rotate, but by keeping the peripheral clearances low and the interengaging faces of the blades long in the axial direction, such rotation can be reduced to negligible proportions. In another modification, Fig. 10, the blade root has a channel 17 running around it in which is placed a pad 18 of yielding material shaped so that recesses are left in which engage correspondingly shaped projections 19 on the adjacent rotor discs 1. A yielding material with good damping characteristics is chosen to .dampen.out any vibration in the blades. The ball-race 15 may be replaced by a laminar element of this material. The clearances between adjacent blades and between the blades and the rotor are chosen so as to limit the amount of tilt. The blade mounting is stated to be suitable also for compressors and impellers.

Title: Purification of irradiated 7-dehydrocholesterol
IPC: A61K31/59
Filed: 1958-10-31
Abstract: Irradiated 7-dehydrocholesterol is purified by treating an alcoholic solution of irradiated 7-dehydrocholesterol with a cation exchange resin in the hydrogen form and an anion exchange resin in the basic form.  The alcoholic solution is preferably passed through an intimate mixture of the ion exchange resins, but, if desired, may be passed first through one resin and then through the other resin.  The treatment may be effected prior to or subsequent to crystallizing from the alcoholic solution the sterol that has not been converted into Vitamin D3 by the irradiation procedure.  The process provides a means of separating from Vitamin D3 and any unirradiated 7-dehydrocholesterol associated therewith, the contaminants and by-products of the process of producing 7-dehydrocholesterol.

Title: Improvements in or relating to screwdrivers and like tools
IPC: B25B23/142
Filed: 1960-10-13
Abstract: 913,388. Screw-drivers; wrenches. GENERAL ELECTRIC CO. Ltd., and SANDERS, T. J. Sept. 19, 1961 [Oct. 13, 1960], No. 35192/60. Class 61. A torque-indicating screw-driver or wrench comprises a shaft having at one end means to engage a screw, bolt, nut, &c. a driving handle and means to transmit driving torque from the handle to the shaft by way of a helical or other resilient spring so that it is deformed in the same way (e.g. by winding up in the case of a helical spring) irrespective of the sense of the torque transmitted. As shown, a screwdriver comprises a cylindrical body provided with a handle 1, the body being partially closed at the end adjacent the handle by a disc 6, partially closed at the other end by a disc 7 and having a ring 13 secured to the interior wall. The shaft 9 provided at one end with a screw-driver tip 10 is located relative to the body 4 by ball-races 11, 12 which cooperate with bearing surfaces formed on the shaft and on the disc portions 6, 7. The shaft 9 is formed with two disc portions 17, 18 which lie in the same general planes respectively as the ring 13 and disc 6. Connecting the disc portions 17, 18 is a stop-pin 19 and two eccentric pins 20, 21. The portion 24 of the pin 19 which lies between the discs 17, 18 is of cylindrical cross-section as are the corresponding portions 25 of the eccentric pins 20, 21. The portion 25 of each of the pins 21, 22 is off-set from the longitudinal axis of the remaining part. A helical spring 30 encircles the portion of the shaft which lies between discs 17, 18. The two ends 31, 32 of the wire forming the spring are straight, extend beyond the periphery of the spring and bear against the portions 25 of eccentric pins 20, 21 respectively, and also bear against further pins 33, 34 lying parallel to the pins 20, 21 and having their ends located respectively in the disc 6 and ring 13. The shaft 9 has secured thereto a drum 26 on which are engraved graduations which co-operated with an engraved mark on the body 4. In operation, when the shaft 9 is held still and the driving handle is rotated one of the eccentric pins secured to the driving handle will tend to push against the end of the spring whilst the other pin will tend to move away from the other end of the spring, the spring thus being wound up so that a torque is then applied to the shaft. On rotating the handle in the opposite direction the other eccentric pin winds-up the spring.
