Title: Improvements in or relating to internal shoe drum brakes
IPC: F16D65/14
Filed: 1943-02-05
Abstract: 562,072. Bowden mechanism. AUTOMOTIVE PRODUCTS CO., Ltd., and PARNELL, F. G. Feb. 5, 1943, No. 1975. [Class 80 (iii)] [Also in Group XXXIV] In brakes of the kind comprising a spreading- device and an anchoring abutment arranged between each pair of adjacent ends of a pair of shoes so that each shoe acts as a leading shoe with either direction of rotation of the brake drum the spreading devices are operated by a single Bowden cable and sheath extending between them and arranged to apply an equalized pressure to them. Fig. 1 shows the back plate 10 of a brake, mounted on the axle casing 11 of a motor vehicle, the brake drum 13 being carried by the adjacent wheel. Spreading devices at each pair of adjacent ends of the shoes 14, 15 are constructed as described in Specification 538,335 and comprise a pair of sectors 31, 32 pivoted at 33 to a plunger 34 and acting upon the webs 16, 17 of the shoes 14, 15 through plungers 22, 23 slidable in a casing 21 fixed to the back-plate 10. The plunger 22 is adjustable in length by the device 26. The plunger 34 is operable either by a hydraulic piston 39 or by a lever 38 pivoted at 45 in a lateral extension of the cylinder member 40. The shoes anchor on the casing 21 through the plunger heads 24. The ends of a Bowden cable 68 are connected to the levers 38 of the two spreading devices, the connection at one end comprising a link 66 with pivots 65, 67 at right angles to each other connecting it to the lever and to a member 64 slidable in a socket 60 connected by a member 58 to a pull rod 62. The ends of the sheath 54, 56 are socketed in the member 58 and in a fixed bracket 52. The cable is tautened by a spring 71 in a casing 72, 73. To allow of adjustment of the cable the sheath is in two parts 54, 56 seated respectively in sockets 76, 74 one screwed into the other. A plug 80 permits of the supply of lubricant to the cable. The pull-rod 62 and the rod 62a for the wheelbrake at the other side of the vehicle are connected to a lever 82 pivoted at 83 to a fixed bracket 84 and operated by the hand or parking brake lever by a rod 86. The lever 82 may be mounted on a lever to equalize the pull on the rods 62, 62a. In operation the pull applied to the rod 62 is transmitted by the member 58 to the end of the sheath 54, 56 and the tension thus applied to the cable 68 exerts an equalized force on the two levers 38. The connections of the Bowden device may be varied ; thus, the ends of the sheath may act upon the levers 38 and the cable be anchored to the back plate at one end and be connected to an operating lever at the other end or one end of the sheath and one end of the cable may respectively act on the levers, the operating force being applied either to the other end of the sheath or of the cable. Instead of the device shown in Fig. 3, the spreading devices may comprise cams operated by levers which move about axes parallel with the axis of the brake. The Provisional Specification refers to Specification 495,834.

Filed: 1956-01-25
Abstract: 822,906. Linear particle accelerators ; velocity-modulated tubes. POST, R. F. Jan. 25, 1956 [Feb. 8, 1955], No. 2448/56. Class 39(1). [Also in Group XL(b)] In a travelling-wave linear electron accelerator, electron bunches produced in a velocitymodulated tube such as a klystron 11, Fig. 1, are injected into the accelerator 13 through a combined electron collector and beam and radiation coupler 22, the phase relationship between the bunched beam and the waves passing through the coupler being so adjusted that only selected bunches are accelerated. The discrimination is preferably in favour of those electrons 180 degrees out of phase with the driven oscillations in the output cavity 21 of the klystron and which attain twice the voltage of the rest of the beam electrons. The cylindrical member 23 of coupler 22 is supported by quarter-wave stubs and has a flared end for collecting a large portion of the electron beam. The member 23 has a narrow opening for collimating the electrons which do pass through. The wave velocity is greater than the beam velocity so that the waves advance in phase. In Fig. 2, 'the coupler is constructed so that a fundamental coaxial mode transforms into a waveguide mode with a phase velocity greater than that of light over the centre portion of the coupler and then back into a coaxial mode. The centre portion has a wall 32 so as to set up a circumferential mode. Small vertical posts 33 ensure matching between the coaxial and waveguide modes. In Fig. 4, the phase of the waves is retarded with respect to the beam by means of fins 36 which provide a slow-wave structure.

Patent GB-654834-A (GB)
Title: Felted cotton fiber textile materials, and methods and apparatus for producing the same
IPC: D04H1/06
Filed: 1947-01-27
Abstract: An unwoven felt-like material is produced by subjecting a body consisting wholly or mainly of cotton textile fibres to the action of a strongly alkaline liquid swelling agent for cellulose, while supporting it substantially free from tensional stress, thus causing intercurling and kinking of the cotton fibres, and contraction of the body in area, and removing the swelling agent without substantially stretching the body.  The swelling agent may be an aqueous solution of a caustic alkali, of sodium zincate or of a quaternary ammonium base such as benzyl trimethyl ammonium hydroxide, but is preferably a 10 to 18 per cent solution of sodium hydroxide at a temperature of from -10 DEG  to +25 DEG  C.  A cotton fibre sheet F, made by superimposing carded webs, may be fed from a roll 10, between feed-rollers 12, floated on the surface of the liquid swelling agent C in a tank 14 and removed therefrom on a conveyer screen 16 which passes round the rollers 18, 34, 36, 38, 40 and 42.  The rollers 12 feed the sheet at a faster rate than the conveyer 16 removes it. Refrigerated caustic soda solution is supplied to the tank 14 from a container 20 through a pipe 22; it enters the tank over a weir 30, is removed at the far end through a pipe 24, and returned to the container 20 by a pump 26.  The width of the tank decreases, and its depth increases as the liquid progresses, so that the rate of flow of the latter decreases.  After removal, the sheet passes over a suctionbox 50, where it is washed by water flowing over the weirs 46, 48, and over the box 60, where it is sprayed with dilute acetic acid from a spray head 56, and washed with water flowing over a weir 58. It then passes between squeeze rollers 66 and is dried by cans 68 or otherwise.  A denser felt may be produced by compressing <PICT:0654834/IV (c)/1> the sheet before treatment, as by passing it between rollers. Other fibres, such as kapok, wool, silk, "Vinyon" (Registered Trade Mark) nylon, or regenerated cellulose, may be mixed with the cotton.  Specification 654,869, [Group VIII], is referred to.
