Abstract: 700,425. Machinery frames. VICKERS-ARMSTRONGS, Ltd. March 28, 1952, [Aug. 1, 1951], No. 18258/51. Class 80 (4) [Also in Group XXV] A method of tensioning tie-rods of press or other machine frames consists in applying hydraulic pressure between a surface on the rod and the member through which it passes. As shown the rod 5 passes through a member 4 and is secured by a nut 11 which bears upon a composite ring member 14, 19. The member 19 has an annular piston portion 22 which enters an annular recess 18 in the member 14 to which hydraulic pressure can be supplied through a passage way 24. In operation the nut 11 is screwed down until it touches the member 19 and hydraulic fluid is then pumped into the recess 18 to force the member 19 and the nut upwards and thereby tension the rod 5. Two semi-circular shear plates 28, 29 may then be inserted in an annular groove 26 of the member 19 and bearing on a shoulder 25 of the member 14, the hydraulic pressure then being released. These shear plates are adapted to be broken on a predetermined overload on the tie-rod. Alternatively the shear plates may be dispensed with and the hydraulic liquid sealed in the recess 18 after the, tie-rod has been tensioned. A pre-set relief valve or a rupturable diaphragm may be provided as a safety device in the event of an overload occurring.

Abstract: 874,000. Radiation pyrometers. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. May 20, 1960 [May 29, 1959], No. 18354/59. Class 40(3) A radiation pyrometer, Fig. 1, suitable for measuring the surface temperature of metal bars 3, comprises a fused quartz rod 1 providing a radiation transmission path to a lead sulphite photocell 4 over a wavelength interval # 2  to # 3  the rod having a first break 5 to accommodate a radiation chopper 6 rotating at 10 c/s. and allowing the alternate transmission over wavelength intervals # 5  to # 2 , # 2  to # 3  and a second break 7 to accommodate a radiation chopper 8 which imparts a 1000 c/s. carrier frequency to the photocell signal. Chopper 6 has alternate blades of perspex and germanium, the perspex blades transmit radiation of the interval #1 to #2 where #1 is zero and #2 is 2Á. The germanium blades transmit radiation over the interval # 2  to # 3 , where # 3  is 2À5Á. The photocell signal comprising the 1000 c/s. carrier modulated at 10 c/s. is applied through an amplifier 9, to a phasesensitive detector 10 and results in two D.C. levels corresponding to the intervals # 1  to # 2  arid # 2  to # 3 . The levels are separated by a synchronous switch 17, carried on the shaft of motor 16 which rotates chopper 6, and applied after smoothing to a potentiometer device 18 for determining the ratio of the amplitudes of the two levels. A reference signal for phase detector 10 is derived from chopper 8 through an amplifier 12. The end of the quartz rod 2 is shaped as shown in Fig. 2 so as partly to encircle a metal bar 3. The pyrometer operates in the range 650-750‹ C.

Title: Improvements in and relating to electron discharge devices
IPC: H01J21/02
Filed: 1934-06-26
Abstract: 441,849. Discharge apparatus. BULL, C. S., 33, Micawber Avenue, Hillingdon, and KEYSTON, J. E., Holly Cottage, Wood End Green, Hayes, both in Middlesex. June 26, 1934, No. 18876. [Class 39 (i)] The invention relates to electron discharge devices of the kind having a cathode, a control grid, a screen grid surrounding the cathode, and an anode surrounding the screening grid, the anode potential being so positive that a substantial amount of secondary emission takes place, and the anode being spaced at such a distance from the screen grid that owing to the space charge of primary and secondary electrons a potential minimum is produced in the anode - screen space which prevents secondary electrons from reaching the screen under operating conditions. Such devices exhibit no inflexion of the anode current-anode voltage characteristic with the screen grid potential equal to the mean anode potential. According to the invention, either the control grid has no supports which extend into the electron stream, or else the thickness of such supports is not substantially greater than the thickness of the wire or the like of which the grid is made. The screening grid supports are preferably arranged in a similar way. By this means electron shadows cast by the grid supports are made too small to allow substantial leakage of secondary electrons to the screen grid. The thickness of the supports in the electron stream should not be greater than three times that of the grid wires, the effective thickness being that measured perpendicular to the electron stream. The grid shown in Fig. 2 is composed of parallel wires 6 joined at their ends to supporting rings 7, 8 which are outside the electron stream. In another form, Fig. 6, the grid is of perforated metal, the perforations 12 being produced by etching or punching. Wire gauze grids may also be used. In an alternative construction, Fig. 5, the grid is a helix 10 wound on supports 9 of the same diameter;. two or more intermeshed helices may be employed. Dimensions and spacing of electrodes in an example are given. Specification 423,932 is referred to.
