Title: Improvements relating to vehicle brakes
IPC: F16D51/50
Filed: 1929-04-05
Abstract: 309,188. Tognotti, H. April 6, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Blocks and shoes acting on drums.-In a brake in which the frictional reaction acting on one shoe when applied to the rotating drum serves to apply another shoe to the drum, one end of one shoe 2 is connected by a link 14 to a crank 13 on a spindle 12 carrying an actuating arm 27. The other end of the shoe 2 is pivoted at 17 to an arm 16 having an arc-shaped edge 18 provided with a tooth 19 engaging a recess in a support 21. The shoe 3 is supported at one end by a flanged pin 24 and at the other by a flanged pin 25 passing through an opening 26 and carries an adjustable pin 23 abutting on the arm 16. The shoes are normally held by springs against stops 2<a>, 3<a>. The spindle 12 passes through a plate 10 which carries a set-screw 11. When by operating the lever 27 the shoe 2 is forced against the brake-drum, this shoe is carried around by the drum sufficiently to effect the application of the shoe 3 to the drum, by engagement of the pin 23 with the arm 16 which pivots about the tooth 19. The amount of the thrust exerted on the shoe 3 is greater in proportion as the pin 23 is nearer the bottom of the arm 16. A diagram is shown from which it appears that the maximum braking effect is obtained, by so arranging the brake shoe that the diameter which passes between the adjacent ends of the shoes is normal to the resultant of the vertical and horizontal forces acting on the vehicle. Force-transmitting mechanism.-In an arrangement for applying the four brakes of a vehicle simultaneously in an equalized manner, the shaft 34 is apparently movably mounted in a bearing 35 which can swing about a vertical pivot 36. The shaft has secured to it an arm 38 to which is pivoted a swing-bar 42 connected to the front wheel brakes, the upper end of the arm 38 being connected by a cable 40 to a swing-bar connected to the rear-wheel brakes. The shaft slides in a guide 37. The pedal 31 is pivoted at 32 to a support 33 secured to the shaft.

Title: Improvements in insulated electrical conductors and method of making the same
IPC: H01B13/12
Filed: 1943-07-02
Abstract: 564,471. Electrical conductors. UNITED STATES RUBBER CO July 2, 1943, No. 10762. Convention date, Aug. 5. 1942. [Class 36] In applying a sewing of a fibrous yarn such as asbestos to an insulated co ductor, e.g. one shown in Fig. 1 in which the metal conductor 10 has an insulating covering of rubber 11 and " Cellophane " (Registered Trade Mark) 12, a number of strands 14 of asbestos yarn are wound helically in a single layer over the layer 12. The construction is adapted to produce an insulating covering of low thickness but capable of being bent without injury to the sewing. To this end the conductor with the sewing applied is treated so as to raise the fibres F Fig. 2, from the strands 14 and then lay these fibres at a definite angle over the adjacent yams to which they are secured by an adhesive, so' that the adjacent strands are bonded together. The conductor with the sewing applied is led from a braked spool 14, Fig. 3, over a driven pulley 17, and the fibres of the strands 14 are raised to the form shown at a, Fig. 1, by air blasts delivered by a jet ring 20 through which .the conductor passes, and which is reciprocated by a slide 26 operated by a crank 30. The fibres are then coated with an adhesive 32 by being passed under a roller 19 arranged in the bath 31 and take the form shown at b, Fig. 1. The adhesive may be a solution of " Vinylite " (Registered Trade Mark), and may be circulated by a pump 33 in a direction opposed to that of the conductor. The coated fibres are then subjected to a wiping operation, which causes them to be set at a definite angle to the strands 14, by passing the conductor through a rotating eccentric horn 36 arranged below a splash guard 60. The process is completed by passage through drying-chambers 40, 41 through an ironing device 52 driven by a pulley 50, and finally to a winding spool. The device 52 may be replaced by an ironing-machine of the kind in which three ironing rollers, Fig. 10 (not shown), are mounted in a rotating squirrel-cage. The asbestos yarn may be replaced by yarns formed of other short fibres such as cotton, wool, or glass. The ironed fibres are indicated at c, Fig. 1.

A heat exchanger, for use in a nuclear reactor (Fig. 1, not shown), beneath a reactor core (R) and within the reactor concrete shell (B), comprises a number of parallel connected heat exchanger units, of which only two 1, 2 are shown, the units being spaced apart and having disposed within them closed parallel finned coils 3, for the coolant, and having their top and bottom ends open for the passage through the unit of the reactor coolant gas, such as carbon dioxide. Each unit has a framework, on which the coils 3 are supported, comprising vertical support struts 6 to which are welded transverse struts 7, the struts defining a longitudinal wall having apertures which permit communication between the space 13 and the interior of the adjacent units. Alternatively, the adjacent unit walls may be formed imperforate to prevent such communication, in which case bridge members 17 are removed and a different support structure 19 provided. In either case straight through flow of reactor gas through the space 13 is prevented either by baffle members 14, extending between adjacent struts 7, or by channel-like members 18, resting on two adjacent struts, so ensuring the absence of adverse temperature and pressure gradients across a unit wall. Similar baffle members may be provided between the outermost heat exchanger units and a casing (20, Fig. 4, not shown), surrounding the same, or alternatively, cover-plates (A, Fig. 1), are made to extend between the outermost exchange units and the reactor shell.

Title: Method of and apparatus for magnetising or demagnetising magnetic record carriers
Inventor: FRIES GUSTAV
IPC: G11B5/49
Filed: 1955-04-18
Abstract: 792,674. Magnetic recording and reproducing apparatus. INGLESBY, J. C. VREDENBURG-. April 18, 1956 [April 18, 1955], No. 11191/55. Class 40 (2). In the art of magnetic recording, a method of magnetizing and demagnetizing a record carrier is effected by means of cathode rays. Fig. 1 illustrates apparatus in which electrical oscillations produced by an interrupter 26 and a spark coil 14 are applied to the electrodes of a cathode-ray tube 8 having an electron-pervious window, known as a Lenard window, slot-like in shape and over which a magnetic tape 2 is passed. The signal so recorded may be reproduced by an ordinary magnetic head 19, and reproduced by a loud-speaker 22 after amplification by amplifiers 20, 21, the intensity of the cathode-ray beam being adjusted by means of a valve 18 controlling the vacuum in the tube 8. The recording is comparable to that of a variable density recording in optical sound films. Such a kind of recording may be made of sound by applying a suitably modulated voltage to a control electrode 30, Fig. 2. A recording comparable to that of a variable width optical recording, Figs. 4 and 5, may be made by producing a beam having a triangular section and oscillating it over the slot-shaped Lenard windows, in accordance with the sound to be recorded, by applying the modulated voltage to the deflector plates X, X<SP>1</SP>. Fig. 7 illustrates a method by which a recording ia made in the form of transverse lines across the film by using a modulated spot beam deflected by saw-tooth voltages. Figs. 8 to 12 (Figs. 9 and 11 not shown) illustrate a method of recording very high frequencies, such as television signals, by means of a cathode-ray tube 52 having a peripheral Lenard window 49 over which the record tape 50 obliquely passes, thereby producing parallel oblique traces, Fig. 10. The modulated beam is deflected by sinusoidal X and Y voltages, displaced in phase from each other by 90 degrees, to move the beam in a circular path 47 which is then deflected by funnel-shaped deflectors Z, Z<SP>1</SP> to the Lenard window 39. Thus, if a 50 c/s voltage is applied to the X and Y plates and the diameter of the cathode-ray tube is 10 cms., a scanning velocity of 1570 cms./sec. is obtained. A scanning velocity of 2000 cms./sec. is considered sufficient for television signals, Fig. 12. Specifications 738,570, [Group XL (b)], and 788,862 are referred to.
