Filed: 1975-01-16
Abstract: 1491554 Polyester fibres CHEMISCHE WERKE HULS AG 16 Jan 1975 [17 Jan 1974] 1897/75 Heading C3R Low-pilling fibres are made of a polyester which contains, chemically incorporated therein as a branching component, 0À005 to 2À0% by weight, based on the acid component of the polyester, of a polymer of the formula in which n is 10 to 10,000, a is zero or 1 to 100 b is 1 to 100, R<SP>1</SP> to R<SP>6</SP> are hydrogen, C 1 -C 3  alkyl, C 1 -C 6  alkoxy or C 6 -C 10  aryl, X 1  is hydrogen, C 1 -C 3  alkyl or an optionally esterified carboxyl group and X 2  is an optionally esterified carboxyl or hydroxyl group. If the polymer is free from ester groups it is added to the polyester after transesterification and before the end of the polycondensation, but if the polymer contains ester groups then it is added to the polyester before or during the transesterification so as to remove the capping ester groups. The examples describe preparing polyethylene terephthalate fibres wherein the following branching components are used: (a) ethylene-maleic acid copolymer esterified with methanol, (b) styrene-maleic acid copolymer esterified with methanol, (c) methylvinyl ethermaleic acid copolymer esterified with methanol, (d) ethylene-vinyl acetate copolymer and (e) polymethylacrylate.

Title: A new or improved automatic machine for sharpening saws
IPC: B23D63/12
Filed: 1921-01-13
Abstract: 157,992. Octave, A. Jan. 13, 1920, [Convention date]. Saws, sharpening.-A grinding.disc k, Fig. 2, operates upon the underside of a tooth of a saw A, and then upon the top of the same tooth, and is finally disengaged from the saw to allow the latter to be advanced one tooth. This cycle of operations is controlled by cams j<1>, j<2>, 10 upon a shaft B. The disc k is mounted on a spindle journaled in a carriage i adjustable on a frame b, which is pivoted to a lever d. Counterweights c, e maintain the disc in a normal position disengaged from the saw A. Counterweighted levers g, h, slidable in sockets s, t pivoted at u to a rack w, engage a trunnion f on the frame b. The end n of the lever g engages a templet p adjustable about a pivot q, and is caused to move thereon by a link e<1> and bell-crank b<1>, a<1>, which contacts with the cam j<1>. The grinding- disc is thus moved over the path o, t<1>, o' shown in Fig. 4. The end of the lever is moved over a templet p<1> by a chain b<2> attached to a pivoted link a<2> engaging the cam j<2>, and causes the disc to describe the path o, t<1>, x, y. The templet p<1> comprises two adjustable sectors m2, la pivoted at n<2> to a slide adjustable in a substantially horizontal direction, and a plate p<1> adjustable in a substantially vertical direction. The cam 10 contacts with the end of a pivoted link 7, which is connected by a rod 5 to a lever 2 carrying at its upper end a screw-adjusted disc 11, to which is pivoted a pusher-rod 1. This link system serves to advance the saw when required and is returned to its normal position by a counterweight 13. The points of attachment of the chain b<2> to the link a and of the rod 5 to the link 7 are adjustable to suit saws of various pitches.

Title: Improvements in the means of propelling or supporting a body, machine, ship or the like
IPC: B63H11/12
Filed: 1924-01-25
Abstract: 231,269. Singleton, G. H. Jan. 25, 1924. Propelling by impact of moving bodies.-Propulsion of ships and aircraft is effected' by a force acting on the vessel and re-acting upon the inertias of a system of moving bodies whereby no re-acting impulse is produced except when adjusted to effect a correction in the position of the system relative to the vessel. The system comprises four power cylinders A, B, C, D, to two of which, such as A, C, working fluid is supplied which acts on the cylinders to produce an impulse on the vessel, the other two B, D being open to exhaust. The reaction on the pistons is caused to act through racks on a double pinion, the relative diameters of which are inversely proportional to the corresponding cylinder diameters whereby the axis of the pinion remains central in the longitudinal guide on which its bearings are mounted. A re-adjustment of the mean position in the guide occurs when the vessel is accelerating or decelerating, such adjustment being spring restrained or similarly controlled.

Abstract: 910,841. Moulding containers. PLASTIC PACKAGING Ltd. April 5, 1961 [Jan. 20, 1960], No. 2134/60. Class 87(2). [Also in Group XVII] A container or container closure is moulded from thin plastic sheet material by means of suction and/or fluid e.g. air pressure in a metal mould body 8 having a separate member 10 rigidly secured to it. Suction passages 14 are formed in the body 8 and a similar passage 13 in the member 10. The sheet material is heated, and forced downwards by a plunger to the position indicated at 1a so that a seal is formed at 14. Suction is applied through the passages 13, 14 and/or fluid pressure may be applied internally to the walls of the sheet material so that the member 10 moulds an inset nozzle in the end of the sheet material. The sheet material in the area of the nozzle becomes thinner than that of the container walls.

Title: Improvements in or relating to devices for producing pulsatory x-rays
IPC: H05G1/20
Filed: 1954-01-25
Abstract: 739,355. Supply systems for X-ray tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Jan. 25, 1954 [Jan. 28, 1953], No. 2159/54. Class 38 (4). To avoid excessive screen-grid current in the intervals between successive discharges of pulsed X-ray tube 2 of the tetrode type excited by periodically applying a cut-off bias Vgl to its control grid 6 to interrupt abruptly current flow through an inductor 3 connected in the anode circuit of the tube, means are provided for so controlling the internal im. pedance of the tube between discharges that the screen-grid current is maintained at a low value. In one arrangement, Fig. 6, this current limitation is effected by a high-valued resistor 28 in series with the voltage source Vg2 for the screengrid 7, undue voltage rise at that grid during the discharge period being prevented by a diode 29 which connects the grid to a relatively lowvoltage tapping on the source. In another arrangement the screen grid is connected directly to its voltage source and a control voltage of waveform suitable to maintain the screen grid current at low value is applied to the control grid of the tube, this control voltage and the periodic bias voltage being applied over diodes to prevent interaction. In the arrangement of Fig. 9, a valve amplifier 16, 21, responsive to voltage changes across a lowvalued resistor 13 in the screen-grid supply circuit, provides an output voltage which is applied over diode 11 to the control grid of the tube and which is of the correct waveform to maintain the screen grid current substantially constant. The periodic bias voltage Vgl is applied over diode 8. In a modified circuit the resistor 13 is connected between the tube cathode and the negative side of the screen-grid current source Vg2, a cathode resistor being included in the anode current circuit. The ratio between the screen-grid and anode currents is then equal to the ratio between these resistors.

In an impeller for an axial-flow fan or the like, the blade base has an ellipsoidal contour whereby the annular area of the passage decreases from the impeller inlet towards the impeller outlet, the geometrical pitch of the blades progressively increases towards the impeller outlet, and the geometrical pitch does not decrease from root to tip in any one plane which is parallel to the axis of rotation. The geometrical pitch varies from root to tip to equalize the absolute velocities at the outlet from the blades. Fixed impeller blades 13 may be followed by auxiliary blades 29 which may be detachable or adjustable, or both, in the manner described in Specification 702,312. The gap, measured in the axial direction, between the blades 13 and 29, is of the order of 0.01 to 0.03 of the overall chord, and may extend over part only of the radial lengths of the blades. The elliptical contour of the impeller hub 15 is continued by a fairing 30 which may be stationary as shown or may be attached to the hub 15. The blades may be of aerofoil or laminar form, the centroids of the blade sections being such that bending stresses are relieved by the centrifugal forces. The mean camber line may be parabolic or may be curved to a radius which varies from root to tip but is not less than that at the root. The fairing 30 may be omitted, and the impeller blade tips and the adjacent part of the fan casing may have a shape which is inverse to that of the ellipsoidal impeller hub. The impeller blades may have a solidity ratio greater than unity and may overlap when viewed in the axial direction.
