Filed: 1933-05-22
Abstract: 420,298. Producing staple fibre yarn from continuous filaments. BRITISH CELANESE, Ltd., 22, Hanover Square, London, TAYLOR, H., and TAYLOR, W. I., c/o British Celanese, Ltd., Spondon, near Derby. May 22, 1933, No. 14721. [Class 120 (iii)] In the direct conversion of continuous filaments into yarn containing staple fibres, the filaments are spread as they are fed to the converting device. Spreading may be effected by passing filaments 1 over guide rods 5 which may, for example in the case of filaments of cellulose acetate, electrify the filaments. The filament bundle preferably has little or no twist before being subjected to spreading, e.g. the filament bundle may be unwound from the bobbin 2 in such a direction as to untwist the bundle. The rollers 3, 3 and 4, 4 break the filaments as described in Specification 410,805, or the filaments may be cut. The resulting staple fibre yarn may be twisted and wound by a cap- or ring-spinning device. Specification 403,739 also is referred to.

Title: Improvements in or relating to contour gauging device
Filed: 1954-05-20
Abstract: 773,088. Contour gauges. SHEFFIELD CORPORATION. May 20, 1954 [May 28, 1953], No. 14813/54. Class 106 (2). A work-piece such as a turbine blade 64 is gauged for departure from theoretical dimensions by setting up the blade &c. in a support 38 angularly adjustable on two shafts 34, 36 at right angles in such a manner that the axes of the shafts intersect at a reference point W in or on the blade &c. from which all other points are measured, locating a gauge member 20 in an initial setting to obtain a gauging indication for the point W along a measuring co-ordinate such as 65, and then adjusting the blade &c. and the gauge member as by the interposition of gauge blocks 57, 61, 55, 54 to set the gauge member at the theoretical position of a second point, say 66, on the blade surface for gauging along a co-ordinate 70. Any deviation from the initial indication will show the amount of departure of the second point from its theoretical position. A blade &c. can be calibrated to take the place of an exact master blade by marking each point gauged with a scriber and recording the errors at each point. The gauge member 20 is longitudinally adjustable in a block 17 slidable on a column 16 fixed to a block 11  slidable in guides 15 on a base-plate 10. The work support 38 is carried by a horizontal shaft 36 rotatable in an arm 12 mounted on a vertical pivot 34 in the base-plate, the shaft 36 having an arm 37 for adjustment by the gauge block 61 against a stop 62. The arm 12 has a depending member 58 for adjustment by the gauge block 57 against a stop 60, and the sliding movements of the gauging member are adjusted by the gauge blocks 54, 55, 56. In use the blade &c. is clamped against a stop 45 so that the reference point W lies at the intersection of the axes of the shafts 36, 34 and gauge blocks are positioned at 56, 57, 61 to align the axes of the shaft 36 and the gauge member 20. The block 17 is lowered into contact with the block 11, a gauge block equal to the distance between the point W and the surface 67 of the mounting block 38 is inserted at 54 and the gauge 20 adjusted along its housing 19 while the work contactor 24 is in contact with the surface 67 until a given intermediate reading is obtained on a gauge, and then clamped. Different predetermined gauge blocks are then inserted at 57, 61, 56 and 54 and a block inserted at 55 to raise the gauge member to the correct height, so that the gauge member is brought opposite the second point 66. On removal of the block 54 the gauge head is moved in to contact the blade and indicates the departure from true position of the second point. For scribing, the gauge member is removed after gauging and replaced by an eccentric scribing point which is turned to scribe a circle around the point gauged. The work-piece is clamped in position by a compressed air operated finger projecting through the block 38 from a cylinder 51. The indicator of the gauge may be pneumatic, mechanical or electrical.

Title: Improvements in electron discharge devices
Inventor: KOMPFNER RUDOLF
IPC: H01J25/16
Filed: 1947-06-05
Abstract: 680,794. Velocity-modulated tubes. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Dec. 2, 1948 [June 5, 1947], 14852/47. Class 39(i) An electronic device comprises a substantially straight waveguide or transmission line section with input and output means, means for projecting an electron beam laterally across the section so that the beam is velocity-modulated by a wave transmitted along the section, the beam being ribbon-like with its width extending longitudinally of the section and twice as wide as the wavelength of the wave so that a wave of progressively increasing amplitude is built up across the width of the beam. A strip cathode 1 emits a ribbonlike beam which is focused by electrodes 2 on to anode 3. The input signal is fed in through a hollow tubular waveguide 4 of rectangular crosssection joined through a tapering matching portion 5 to a length of rectangular waveguide 6 having a smaller transverse dimension than 4 and terminated by a non-reflecting portion 7, or connected by a transition section to another waveguide portion. The amplified output signal is excited in a correctly terminated waveguide 8 of small transverse dimension leading through transition portion to the output waveguide 10. Longitudinal slots 11 are formed in the wider walls of waveguides 6, 8, and are, if necessary, fitted with transversely barred grids 12. The space charge effect on focusing may be counteracted by a strong magnetic field. In another construction a single waveguide is used and the beam after velocity modulation is reflected back. Transmission lines of the parallel wire open line type or a coaxial line may replace the waveguides. The tube can function as an oscillator by providing feed back and controlling the frequency by variation of the feed back path or the beam voltage, or as a pulse amplifier by applying the pulses to a control grid adjacent the cathode or by pulsing the beam voltage. An additional waveguide terminated non-reflectively at each end may be interposed between the input and output waveguides. The tube is adaptable for frequency multiplication by making the width of the catcher guide an integral fraction of the width of the buncher guide and selecting the appropriate harmonic. The buncher or input guide can be of uniform cross-section throughout its length in the beam path, but the catcher output guide is preferably tapered, beyond the point at which the r.f. voltages have built up to the beam voltage.

Abstract: 1428021 One-way friction brakes GITAC 28 March 1973 [29 March 1972] 14939/73 Heading F2E A shaft drive mechanism which includes a driven shaft and a device for taking up the clearance between two contacting elements of the mechanism makes use of resilient retardation of the driven shaft and comprises a spiral spring having at least one convolution prestressed between the driven shaft and an abutment and tending to apply to the shaft a torque in the opposite direction to the normal direction of rotation imparted to the shaft. As shown in Fig. 1, meshing teeth on pinions 3 and 2 on driving shaft 4 and driven shaft 1 respectively have clearance, compensated for by placing around shaft 1 a spiral spring 5 having one end secured to a stationary abutment 6 and the other end bearing frictionally against shaft 1. The spring is pre-tensioned so that its convolutions have a tendency to tighten, so that with the shaft 1 being driven in the counter-clockwise direction f 2 , the spring applies a torque in the clockwise direction. In Fig. 2, the inner end 5b of the spring is located between two friction shoes 7, 7a, disposed on shaft 1 and pressed into contact therewith by the innermost convolution of the spring. The shoes may be interconnected by a flexible strip or hinge, or they may be replaced by a split sleeve.
