Abstract: 853,835. Windscreen wiper systems. GENERAL MOTORS CORPORATION.. Aug. 10, 1959 [Aug. 20, 1958], No. 27235/59. Class 138(1). A windscreen wiper system has a pair of wiper arms and blade assemblies arranged to oscillate in opposite senses through partially overlapping tables on a vehicle windscreen without contacting each other. The arm 36 carrying a blade 38 is oscillated by a crank 56 driven by an electric motor 24 and coupled to the arm 36 by a link 64 and drive arm 32. The crank 56 also drives the arm 46 carrying the second wiper blade 48 through a link 68, reversing link 52, connecting arm 50 and drive arm 44. In order to prevent interference between the blades, the blade 38 has a greater angular stroke A than the stroke B of the blade 48, and the drive linkages are, so constructed that the blade 38 has a lower angular velocity adjacent each stroke end than in the middle portions of its strokes, and the blade 48 has a greater angular velocity adjacent the stroke end at the side near the blade 38 than at the other stroke end. The shaft 28 carrying the crank 56 may be displaced to vary the throw of the crank to move the blades into their forked positions adjacent an abutment at the lower edge of the windscreen.

Title: Improvements in or relating to the cutting of the teeth of gear wheels
IPC: B04B9/12
Filed: 1921-10-17
Abstract: 190,303. Parkinson, E., and Smith, C. H. Oct. 17, 1921. Shaping; tools.-Tilting tool-boxes of the type adapted to cut on both strokes and to carry roughing and finishing cutters are applied to gearcutting machines. In the form shown in Fig. 1, the holder 10 carried on a pivot 11 is provided with cutters 16, 17 secured by a wedge member 19, cover plates 20 being provided to prevent the ingress of cuttings. The tool-holder is tilted at opposite ends of its stroke by means of a rack 13 engaging a quadrant 12 on the holder and actuated through friction plates from a wheel 14. The arrangement is such that when the tool slide 18 starts to move in either direction the friction plates prevent the rotation of the wheel 14 and thus the movement of the rack until the tool-box has been tilted whereupon slip of the wheel 14 and movement of the rack with the slide takes place. A spring-controlled plunger may engage recesses 13A to hold the tool-box in position. Other methods of tilting the tool-box at the ends of the stroke are described. In a modification, Figs. 3 and 4, a single cutter 16 of rack form is adapted to cut on both faces and is initially clamped by a screw 23 which prevents movement of the cutter while the clamping-wedge 19 is moved endwise by a screw 23A. A packing plate 24 is provided to limit the movement of the toolbox at one end of the stroke.

Title: Process for preventing the discoloration of mercury-carrotted fur by water containing carbonates and/or bicarbonates
IPC: D01C3/00
Filed: 1948-10-22
Abstract: Mercury-carrotted fur or felt prepared therefrom is boiled in water to which has been added an ammonium salt of a strong acid to remove carbonates and/or bicarbonates.  Suitable salts are ammonium sulphate and chloride.  The ammonium salt may be added in amount chemically equivalent to the amount of carbonate and bicarbonate dissolved in the water, in which case the solution should be boiled for 10 minutes prior to the boiling of the fur or felt, or alternatively it may be added in excess, in which case no preliminary boiling of the water is necessary.  In an example, to 100,000 parts of natural well water of 13.6 degrees (French) total hardness 20 parts of ammonium chloride is added, and the solution boiled for 10 minutes.  A mercury-carrotted felt hood is then boiled for 15 minutes in the water, and is found to have suffered no discoloration as a result of the boiling.ALSO:Water containing dissolved carbonates and/or bicarbonates is purified by addition of an ammonium salt of a strong acid and boiled.  It may then be used for boiling mercury-carrotted fur or felt prepared therefrom (see Group IV(c)).  The ammonium salt may be added in amount chemically equivalent to the dissolved carbonate and bicarbonate, in which case the solution should be boiled for 10 minutes prior to boiling the fur or felt, or it may be added in excess, in which case no preliminary boiling is necessary.  Suitable salts are ammonium chloride and sulphate. In an example 20 parts of ammonium chloride is added to 100,000 parts of natural well water of 13.6 degrees (French) total hardness and the solution boiled for 10 minutes.  A mercury-carrotted felt hood suffered no discoloration on being boiled for 15 minutes in the resulting water.

Title: Improvements in or relating to web-, yarn-, or film-winding mechanisms
Inventor: WHITE JOHN ALFRED VICTOR
IPC: B29C53/32
Filed: 1955-09-27
Abstract: 809,508. Winding yarns, tension regulating. BRITISH CELLOPHANE Ltd. Sept. 21, 1956 [Sept. 27, 1955], No. 27536/55. Class 120(2) [Also in Group XVI] In a yarn winding mechanism, means for controlling the tension of yarn comprises one or more friction discs driven from the roller, over which the yarn passes immediately preceding winding, at a peripheral speed exceeding that of the roller, the friction disc or discs driving the mandrel by frictional engagement therewith, and means for varying the pressure between the winding mandrel and friction disc or discs. As shown, as applied to web-winding mechanism, rollers 11, Fig. 2, feed web material towards a winding mandrel 14 supported by bearings 15 on arms 22 the inclination of which may be varied by a screw 23. A chain 13, driven by one of the rollers 11, drives discs 12 consisting or covered with friction material, engaging the winding mandrel 14. The discs are preferably driven at a peripheral speed at least 25 per cent greater than that of the mandrel at the points of contact therewith. Levers 16 are pressed against the winding mandrel 14 by air cylinders 17 controlled by a pressure regulating valve 18, such that the slip between the discs and mandrel may be adjusted. As the diameter of a roll being wound on the mandrel increases so the pressure between the mandrel and discs 12 increases, since the component of weight acting towards the discs increases. Web tension can be controlled by varying the pressure in the cylinders 17 and also by adjustment of the inclination of arms 22. In a modification, the air pressure is controlled automatically by a valve 24, Fig. 3. The valve 24 has a variable orifice 25 the opening of which is controlled by an arm 26 rocked as a result of the increasing diameter of a roll being wound. A manually controlled valve 29 is arranged in the supply to cylinder 17. The initial web tension is controlled by varying the setting of valve 29 and a bleed valve 31 when the valve 24 is closed. As the roll diameter increases arm 26 is swung about its pivot and the valve 24 is progressively opened, thereby varying the pressure supplied to the cylinders 17. Thus, the torque applied to the mandrel 14 is varied to preserve constant web tension. Specification 694,047 [Group XVI] is referred to.

Abstract: 426,950. Electric - lamp holders. GROTE, E. R., Spencer Hill Road, Wimbledon, London. Oct. 6, 1933, No. 27609. [Class 39 (ii)] Wall or like sockets of tubular form for attachment to tubular electric lamps provided with parallel unipolar caps are arranged to connect end to end with conduit tubing, and comprise an insulating sleeve 2, Fig. 3, enclosed within a metal clamping sleeve 1 which, at the mouth of the socket, is flanged inwardly to engage an insulating plug or sleeve 3 and retain it within the upper end of the sleeve 2, the lower end of the sleeve 1 being adapted for connection to the end of the conduit tubing 9. Preferably, the lower end of the outer sleeve 1 is screw-threaded to receive a screwed ring 5 which serves to couple it to the conduit and also engages a shoulder 7 on the insulating sleeve 1 to clamp the latter in position. The contact member located within the sleeve 1 is preferably of the form described in Specification 427,009, comprising a U-shaped clip 19, Fig. 7, straddling a metal block 20 formed with an axially bored screw-threaded nipple 27 through which a wire is threaded and then passed through a lateral hole in the nipple and secured by a clamping-nut 29. The upper and lower faces of the contact block 20 are respectively located between lugs 22, Fig. 8, on the upper insulating sleeve or plug 3, and an internal seating 21 provided in the sleeve 1. A slight longitudinal movement of the lamp relatively to the socket is provided for by elongating the aperture 3<a> in the plug 3, the correct position of the aperture being assured by providing nibs 25 on the lugs 22 to engage notches 26 in the top edge of the insulating sleeve 1. Two sockets may be located side-by-side upon a single fitting, or two contacts may be located within separate insulating-sleeves in the same clamping-member to mount a lamp having a tubular body of looped or substantially circular form. A number of such lamps may be arranged radially about a central fitting provided with the sockets.

Abstract: 242,653. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Goldsmith, A. N.). Nov. 6, 1924, [Convention date]. Fading, preventing; thermionic generators and modulating systems; harmonics, producing and utilizing.- To avoid the effects of fading the frequency of the transmitted wave on which signals are superimposed is varied over a range preferably not exceeding 10 per cent. The frequency at which the frequency is varied is greater than the signal modulation frequency and may be supersonic or in the case of telegraphy above the " dot " frequency of the signal and when fading is pronounced mav serve as the heterodyne. The variation at the transmitter may be produced by varying the capacity or the inductance in a tuned circuit and the receiver is " broadly " tuned. Fig. 4 shows a master oscillator valve 16 and a modulating valve 15 the output from which is applied through an amplifying system 23 to an antenna 26. The wave-length variation is effected by variation of the inductance 21 which is closely coupled to a coil 33<1> in the plate circuits of balanced valves 38, 38<1>, which are excited by oscillating valve 39 and function as rectifiers, causing current to flow alternately in the two halves of the coil 33<1>. This arrangement is stated to give an approximately sinusoidal variation of the frequency. In a modification, Fig. 7, the oscillator 39 instead of being directly coupled to the coil 34 is coupled through a rectifier 50 and a number of circuits 53 - - 56 which are tuned to harmonics so that the wave-form of the output may have any desired form and preferably so that the form and consequently the variation in frequency may be obtained as shown in Fig. 6. Alternatively, by shaping a rotating screen adjacent to the inductance, the frequency variation may be arranged to conform to any desired law.

Abstract: 959,822. Disc brakes. GIRLING Ltd. Aug. 9, 1960 [Aug. 15, 1959], No. 27974/59. Heading F2E. A caliper-type disc brake has friction pads 17 the centre of pressure 23 of which is displaced from the line of action 22 of the applying force and move towards each other as the pad wears, so that the drag forces turning moment on the pads during brake application is substantially balanced throughout the pad's life, thus making for even wear. As shown, the edges 21 of the friction pads 17 are inclined from the backing plates 16 towards the disc 11 in a rearward sense relative to the disc's direction of rotation (arrowed). The balance of the drag forces' turning moments is expressed by equating Fut with fx where F is the force exerted by the piston, u is the coefficient of friction between pad and disc, T is the pad thickness and x is the distance between 22 and 23 at right angles to the line of action of F. In other embodiments, instead of inclining the edges of the pad, the pad is guided or the line of action 22 is applied, at an inclination to the surface of the disc. Specifications 742,338 and 828,961 are referred to.
