Title: Improvements in and relating to roller conveyors
Inventor: PARKER WALLACE JAMES
IPC: B65G13/00
Filed: 1967-05-11
Abstract: 1,149,455. Roller conveyers. W.J.PARKER, and W. M. PARKER. 9 May, 1968 [11 May, 1967], No. 21947/67. Heading B8A. In a roller conveyer comprising parallel rollers carried by spindles supported by a pair of parallel stringers, each spindle has at least one axially extending flat face welded to a stringer. A roller spindle 13 of square cross-section is welded at 15 to an angle-section stringer 10 whose horizontal flange is welded at 12 to a spacer bar 11 of square section. Anti-friction bearings are provided between the roller and the spindle. The spindles and spacers may be of triangular or other section which gives flat end faces to rest on the stringers. The spindles may be welded to the horizontal flanges of the stringers, Figs. 5-8 (not shown), and by arranging that the vertical flanges extend upwards from the horizontal flanges the vertical flanges form guides for goods being conveyed.

Title: Improvement in vibrator circuit
IPC: H02M7/62
Filed: 1944-11-08
Abstract: 591,278. Converting. PLESSEY CO., Ltd. Nov. 8, 1944, No. 21972. Convention date, Dec. 15, 1943. [Class 38 (ii)] To increase the contact-life by, reducing the severity of the starting conditions in a vibratoryinterrupter circuit in which interruption of current in the primary of a transformer induces in the secondary a high voltage which is rectified, the initial current is limited for a period determined electromagnetically. A vibrator 10 which-operates in conjunction with an -electromagnet 17, by alternately engaging contacts 11, 12 makes and breaks the current from a battery 18 through the centre-tapped primary 13 of transformer 14 and thereby develops a high voltage in the secondary 15 which is connected to the full-wave rectifier 16. When starting switch 19 is closed, the initially heavy current, which may occur if the residual magnetism aids the primary flux so that saturation is reached, is limited by a resistance 22 and traverses the winding of a retarded relay 21 which, after a short delay caused by a copper slug 23 moves armature 24 to shortcircuit the resistance 22. The winding of relay 21 may form part of an interference filter comprising choke 20 and condensers 26, 27. In one modification, the coil of the retarding relay may be connected across the battery 18, Fig. 2 (not shown), while in a further modification the retarding relay may be differentially wound with a current and a voltage coil, which are initially balanced, but as the initial current decreases, the voltage winding assumes control and operates the relay to short-circuit the resistance, Fig. 3 (not shown). Specification 566,537 is referred to.

Abstract: 295,030. Bolinders Mekaniska Verkstads Aktiebolag, J. & C. G. Aug. 5, 1927, [Convention date]. Cutting-edges, shaping and treating; gauges.- In a machine for grinding cutters, for example, the thin blade cutters of planing-machines, the cutter-holder consists of a shaft 1 upon which is rotatable and slidable, by means of handles 20, a support 2 having projecting arms 3 and rotatably carrying a shaft 5 to which an arm 7 is secured by means of a screw 6. The cutter blade 11 is clamped against the support 2 by springs 12 carried by the shaft 5, the springs being moved to clamp the blade by a screw 13 acting on the lever 7. The back edge of the cutter rests against an abutment bar 10, which is moved parallel to itself, to position the cutter against a gauge 24, by pins 9 carried by crank discs 8 rotated together, through worm gearing 17, 18 by hand wheels 16 on the spindles 15 of the discs 8. In operation, the holder is turned over on the shaft 1 until the arms 3 rest on a bar 4, and is then reciprocated on the shaft with the cutter edge in contact with a cup-shaped grinding-wheel 21; on completion of the grinding, the support is turned back until the arm 7 rests under the bar 4, and the screw 13 is loosened, permitting the support 2 to fall away from the blade for removal thereof and insertion of another blade. The gauge 24 is slidable in a sleeve 23; the shaft 22 of the grinding-wheel 21 is hollow for the supply of water, which is spread over the wheel by centrifugal force.

Abstract: 1,255,644. X-ray diffraction apparatus- ROLLS-ROYCE Ltd. 9 May, 1969 [10 May, 1968], No. 22299/68. Heading H5R. [Also in Divisions G1 and G2-G3] Apparatus for examining a fibre which has crystallites in a preferred orientation, to determine the value of a mechanical property of the fibre, comprises an X-ray generator 14 producing an X-ray beam: 13 which is diffracted from a point 15 after passing through the fibre, the intensity of the diffracted beam being measured by detectors 23, 24, 25. As shown, the fibre is passed continuously from a roller 11 to a roller 12 and the detectors are arranged to move on a part-spherical surface defined by a dish 20 having its centre of curvature at the point 15. The movement of the detectors is controlled by servomotors located in the base 20, detectors 23 and 24 being movable along a fixed radius arm (22), detector 25 being movable along a rotatable arm 26, while the whole dish is rotatable about its centre. By moving detector 23 to the position of maximum diffracted intensity, and detectors 24 and 25 to positions corresponding to a predetermined amount (say ¢) of this intensity, and then measuring the respective angles subtended by pairs of detectors at point 15, or the centre of dish 20, the crystallite size or orientation is determined. From this information and from calibration graphs (Figs. 1, 2, not shown) an average value of Young's modulus for the fibre may be determined.

The heater may also be a burner with a vertically adjustable wire mantle. The position of the heating element may be adjusted. Reflecting heaters of this kind may be arranged around an oven chamber as shown in Figs. 7 and 8. The heaters are hinged or detachably secured to the oven structure to facilitate inspection and renewal.
