Title: Improvements relating to supports for thermionic valves
Inventor: HOPKINSON KENNETH
IPC: H01J19/66
Filed: 1953-08-04
Abstract: 779,578. Discharge tubes. MINISTER OF SUPPLY, and EDISON SWAN ELECTRIC CO., Ltd. Aug. 4, 1954 [Aug. 4, 1953], No. 21536/53. Class 39(1). [Also in Group XL(c)] A shield for a thermionic valve comprises a sheet metal surround 1, having attached to its inner surface spring members 6, 7 so shaped as to make contact with a substantial part of the valve, in order to provide improved heat conduction from the valve directly to the chassis or casing on which the surround and spring members are mounted. Lugs 2 enable the surround to be secured to a socket, preferably of polytetrafluoroethylene, which is mounted on a chassis 17. The socket has an upwardly extending boss 8 for locating the surround, and through the centre of which extend the valve leads, to be attached to arms 13 of two-limbed prongs, the other arms 14 being connected to external circuit elements. One of these prongs may be formed as an earthed screening strip. A detachable screening can 18 may be secured to the surround 1 by bayonet fastenings 19.

IPC: C08F4/16
Filed: 1960-06-20
Abstract: An ethylene polymerization catalyst is prepared by grinding under inert conditions a mixture of Ti and TiCl3, the mixture not being heated strongly before or during the grinding. The grinding may be effected in an inert liquid hydrocarbon (e.g. one which is also suitable for use in the polymerization reaction) or under an inert gas such as nitrogen or a noble gas.

Title: Abrasive articles and method of manufacture thereof
IPC: B24D18/00
Filed: 1946-07-19
Abstract: 624,509. Abrasive articles. NORTON GRINDING WHEEL CO., Ltd. July 19, 1946, No. 21630. Convention date, July 19, 1945. [Class 60] An abrasive article comprises a rigid abrasive part and a rigid support or backing bonded by cured or set synthetic resin between adjacent surfaces on said abrasive part and backing, the resin having voids or connected spaces to provide column or post portions each of which bridges the space between said surfaces. An abrasive annulus 10 is secured to a rigid backing plate 11 by columns 13 of synthetic resin joined by webs 14 to enclose voids 15. To form and reinforce the columns an open mesh fabric, which may be of glass fibre, is coated with a liquid resinous cement and pressed between the coated faces of the annulus 10 and backing plate 11 while the cement is allowed to set, with or without the application of heat. The columns may be formed, Fig. 6, by coating the opposing faces of the annulus 10 and backing plate 11 with semi-liquid cement, placing pellets G, for example poppy seeds, between the faces, applying pressure and curing. In this case the voids 15 are interconnected and air or liquid coolant may be circulated through. To lessen the strain on the bond or join when the wheel is being used and has become heated and expands at a different rate from the backing plate, the join may be prestressed by using a cement which sets at a temperature between normal temperature and that at which the wheel operates. To diminish still further the effect of the different rates of expansion a cup wheel may be constructed as in Fig. 9 with three annuli 10, P<SP>1</SP>, P<SP>2</SP> each joined by columns the annulus <SP>p2</SP> being so joined to the backing plate 11.
Patent GB-909657-A (GB)
Title: Improvements relating to the production of regenerated cellulose filaments
Inventor: SHARPLES EDWIN HOLROYD
IPC: D01F2/06
Filed: 1958-07-07
Abstract: Regenerated cellulose filaments are made by spinning a viscose containing 0,5-6% by weight of boron phosphate, based on the weight of cellulose present in the viscose.  The boron phosphate should be added to the viscose immediately before spinning, or alternatively a quantity of boron phosphate greater than that required during spinning should be added to the viscose, to compensate for loss due to hydrolysis by the sodium hydroxide in the viscose.  A slurry of boron phosphate in viscose, or preferably in sodium carboxymethyl cellulose, may be injected continuously into the viscose supply to the spinning jet. Preferably the boron phosphate has a particle size of less than 2 microns.  Addition of boron phosphate delustres the filaments, without imparting the chalky whiteness resulting from addition of titanium dioxide.

[Class 61 (ii).] In a vice of the kind wherein the jaw gap may be altered by the usual hand-adjusting screw and also by foot without rotating the screw the foot actuation is effected through a face cam or worm with self-locking action. The movable jaw b is adjustable on the fixed jaw body a by the adjusting screw c threading in the jaw b. The foot actuation is by treadles k and chains i connected to a two-armed lever d fitted with a face cam e, Fig. 4, coacting with a similar cam fixed to the body a. A spring l acting against a collar n slidable on the screw c but held against rotation, which collar n bears against a collar m fixed to the screw, releases the grip of the jaws when the treadle-lever d is reversed. A collar f slidable on the screw but held against rotation by a pin g fixed to the body a is interposed between lever d and the head h of the screw to prevent rotation of the latter when lever d is actuated. In a modification, Fig. 5, the face cam is replaced by a worm o so that the gripping pressure is released as well as applied by the foot-lever. As before, a slidable collar f held against rotation by pin g and interposed between screw head h and lever d prevents rotation of the screw when the lever is actuated. A cap p fastened to lever d engages outside the screw head h and causes the screw to follow the longitudinal movements of the worm, a disc q being interposed between cap p and screw head h and held against rotation by pin g.
