Title: Improvements in or relating to Fluid Braking Systems.
IPC: F16D65/14
Filed: 1967-05-09
Abstract: 1,190,602. Disc brake. ALFRED TEVES G.m.b.H. 9 May, 1967 [23 Aug., 1966], No. 21524/67. Heading F2E. A fluid-operated disc brake has a slack adjuster disposed within and between two opposed brake operating pistons 3, 4, the adjuster including a resilient, deformable member 11 which yields when the fluid pressure exceeds a selected value to render the adjuster inoperative. The disc brake has a caliper 1 and a cylinder 2 containing the opposed pistons 3, 4. A pin 9 extending through the zones of the two pistons is in screw threaded engagement with a sleeve 8 receiving a Belleville washer 13 which abuts a ring 10 in the piston 3. The washer 13 is arranged to deflect only when forces greater than the normal brake applying forces are applied. Passages 17, 19 in the pin permit the passage of hydraulic fluid therethrough. On operation of the brake with normal forces a pin 14 carried on the pin 9 rides along an inclined surface 18 of a notch in a flanged member 13, the latter being held against rotation by friction between the flange and a ring 15, the pin 9 thus rotating in sleeve 8, against spring 12, to take up the normal clearance. On release of the brake spring 12 resets the member 13. If excessive brake-applying force is applied the Belleville washer 11 yields, preventing the slack adjusting mechanism taking up clearances due to bending of the caliper.

Title: Improvements in or relating to electron valves having a luminescent screen particularly to tuning indicator valves
IPC: C09J7/21
Filed: 1950-09-08
Abstract: 690,757. Electron beam apparatus. SIEMENS & HALSKE AKT.-GES. Sept. 8, 1950 [Sept. 9, 1949; Dec. 9, 1949; Dec. 9, 1949; Jan. 23, 1949; Feb. 6, 1950; Feb. 10, 1950], No. 22233/50. Class 39(i). An electron valve, for example a tuning indicator valve, comprises an elongated cathode, a luminescent screen anode of elongated form facing the anode to provide a luminous column whose length can be varied, and an elongated non-cylindrical control electrode situated between the cathode and anode and having at least one aperture therein to serve both for the control and for the screening of the electron flow to the anode without the use of additional bunching or deflecting electrodes. In Fig. 1 the cathode 1 is indirectly heated, the control electrode 3 is a diaphragm with a triangular aperture, and the anode is a glass rod 7 provided with a groove 8 in which is disposed a luminescent material; an auxiliary anode comprising the plates 4 and 5 may be provided. In a modification, Fig. 2 (not shown), the electrode 3 is tilted instead of being in a plane parallel to the anode and cathode. In Fig. 3 the control electrode 14 has a rectangular aperture and is curved towards the anode. The control electrode may have two apertures, Fig. 4 (not shown), or a double aperture as in Fig. 5. When this tube is mounted in a receiver it is preferably connected so that when the receiver is off tune the anode shows a continuous line; as the receiver approaches proper tuning the indication breaks into two lines which gradually diminish in length. The cathode 20 may be directly heated and the anode current of the valve stage to be tuned may be carried partly or wholly through the filament; on reaching exact tuning the anode current is reduced, resulting in reduced heater current and consequently a darker indication on the fluorescent screen which reinforces the darkening effect due to the reduced lengths of the lines. The control electrode may be a frame 30, Fig. 7, instead of a diaphragm and screening electrodes at cathode potential may be arranged on either side of the frame, Fig. 8 and 9 (not shown). In another arrangement, Fig 10, the control electrode 48 has a varying depth along its length to give a varying control effect, and the same result may be obtained by using a frame electrode as shown in Fig. 15.
