Title: Brake lining slack adjusting device
IPC: F16D65/56
Filed: 1972-03-09
Abstract: 1318166 Brake slack-adjusting devices ALFRED TEVES GmbH 9 March 1972 [13 March 1971] 10938/72 Heading F2E In a slack-adjusting device including a pressure element such as a piston 2, Fig. 1, disposed in a cylinder 17 and displaceable in relation to an adjustment spindle 3, and an adjustment nut 7 screwed on to the spindle 3 and engageable with the pressure element 2, the adjustment nut 7 is provided with a conical portion 27, an axially-displaceable catch ring 8 is arranged about he adjustment nut 7 and has an end portion 28 engageable with the conical portion 27 of the nut 7, the catch ring 8 has a radial projection 10 engaged in a guide slot 11 (see also Fig. 2) in the wall of a cylindrical extension 22 of the pressure element 2, the adjustment nut 7 being located within the cylindrical extension 22 and the guide slot 11 extending at least partially at an angle to the longitudinal axis of the spindle 3, and a friction ring 5 is arranged about the nut 7 adjacent the catch ring 8 and is engageable with the catch ring, the friction ring 5 being in frictional contact with the inner surface of the cylindrical extension 22. As shown, the other end of spindle 3 is non- rotatably secured in a piston 1, Fig. 1, opposed to piston 2, in a fluid-pressure actuator for an internal shoe-drum brake, but the piston 1 could be combined with the cylinder. The slack adjuster may be used in connection with disc brakes. In operation.-When pressure fluid is supplied to chamber 18 between the pistons, piston 1, spindle 3 and nut 7 move to the left while piston 2, friction ring 5 (frictionally retained in extension 22 by a spring ring 6) and catch ring 8 (entrained by friction ring 5) move to the right, until the lining clearance has been traversed, whereupon end 28 of catch ring 8 abuts conical extension 27 of nut 7. If wear has occurred the pistons continue to be moved apart, so nut 7 now entrains catch ring 8 which in turn entrains friction ring 5 and slides it, against the resistance of spring ring 6, leftwards inside extension 22. At the same time, catch ring 8 must rotate by reason of engagement of its pin 10 in inclined slot 11, and because catch ring end 28 is in forced contact with conical portion 27 of nut 7, nut 7 is rotated by catch ring 8. The length of the spindle-nut combination is thereby increased. On release of fluid pressure, the pistons reapproach until a retaining ring 9 on nut 7 contacts friction ring 5, at which stage nut 7 is free of catch ring 8, so piston 1 through spindle 3, nut 7 and ring 9 pushes rings 5 and 8 to the right again, relative to piston 2. Catch ring 8 must rotate back again to its former position because of engagement of its pin 10 in inclined slot 11, but nut 7 is not rotated this time because ring 8 and nut 7 are no longer in contact. When the clearance L is restored, the end of nut 7 contacts piston 2 once more. During this release movement, spring 6 prevents friction ring 5 from twisting, and, in turn, contact between ring 5 and retaining ring 9 on nut 7 also prevents nut 7 from rotating back again.

Title: Improvements in or relating to devices for automatically regulating and controlling the temperature of spaces or of the contents of vessels or the like
IPC: G05D23/275
Filed: 1922-04-12
Abstract: 197,513. Bader, T. April 21, 1922. Automatic circuitbreakers; mechanically tripped a n d redeased switches; clockwork actuation. - An apparatus for automatically regulating the temperature of heating plants, incubators, and the like comprises an electric switch 45, Fig. 1, operated by clock-work, the locking and releasing means of which is controlled by an expansion thermometer 25, Fig. 3, through the medium of links, levers, or like wholly mechanical means. In t h e construction shown, the rotation of the switch 45 through successive steps of 90‹ so as alternately to make and break the main circuit is controlled by a clock-work driven wheel 41 having a series of notches 40 which are engaged by a pawl 39 mounted on one end of a lever 37 which is actuated by the lower end 36, Fig. 4, of a temperature-setting pointer 32 adjustably clamped on a spindle 31 in front of a temperature scale 34. The movements of the spindle 31 and pointer 32 are controlled through the medium of a pinion 30, toothed sector 29, lever 28 and link 26 by the expansion thermometer 25, which consists in known manner of a spiral capillary tube con. nected to a mercury container 23. When the temperature reaches a predetermined maximum, the end 36 of the pointer acts on one inclined surface 49 of the lever 37 and releases the pawl 39, thus allowing the wheel 41 to rotate until the pawl engages the succeeding notch 40 and so breaking the main circuit at the contacts 47, 48. The circuit is re-established when the temperature has fallen sufficiently to cause the end 36 of the pointer to engage the opposite incline 50. In the case of electric heating, the switch 45 may be arranged directly in the heating circuit, or, in the case of heating by other means, it may control a motor operating a valve. The inclines 49, 50 are preferably of different angularity to compensate for the variable force exerted by the spiral 25 in expansion and contraction, and the pointer 32 is mounted so that its weight prevents it from lodging on the highest point of the inclines.

Abstract: 795,060. Cathode ray storage tubes. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 20, 1955 [April 23, 1954], No. 11393/55. Class 39(1). The target of a memory storage tube comprises a mica sheet 3, Fig. 2, having a barrier grid 12 of at least one set and preferably two sets of crossing wires on one side and a conductive backing plate 13 on the other side, the surface of the mica sheet 3 in contact with the grid 12 being roughened. A secondary emission collector grid 11 is disposed between the screen and gun. The roughening of the surface of the mica sheet is of the order of a fraction of a MIL, and is achieved by coating the dielectric with a metallic oxide such as MgO or Al 2 O 3  or with a phosphor such as magnesium tungstate or zinc sulphide, or by grinding or lapping the dielectric with one or more of these insulating materials, e.g., Al 2 O 3 . In the latter case Al 2 O 3  particles are pressed into the surface during the lapping operation. If a phosphor coating is used the backing plate is transparent to allow visual observation. The backing plate 13 is an evaporated coating of Al. The collector grid 11 is of tungsten wires making an angle of 45 degrees with the two sets of tungsten wires of grid 12 and a spring 17 presses the mica sheet 3 against wires 12. Grid frames 15, 16 are of ceramic having a matching coefficient of expansion with the grid wires and the entire structure is enclosed in a stainless steel frame 14. Writing is achieved by pulsing the back plate while leaving the beam on the information stored being of binary form as described in Specification 762,294 and during the reading an output is taken from the backing plate. It is stated that noise generated at the back plate during reading, writing, and when the beam is turned off and redistribution of secondary electrons are avoided or reduced by the construction of the invention.
