Title: Slack adjuster mechanism
IPC: F16D65/14
Filed: 1975-06-11
Abstract: 1480855 Slack adjusting brake actuators BENDIX CORP 11 June 1975 [1 July 1974] 25080/75 Heading F2E In a brake actuator of the type comprising a lever 30 for rotating a drive shaft 24 to actuate the brake (e.g. by means of an S-cam) and an adjustment shaft 34 for automatically rotating shaft 24 (e.g. by means of worm and worm gear 32, 36) when lever 30 is rotated by more than a predetermined amount in the brake application direction, shaft 34 is also normally adjustable and a clutch is arranged to disconnect the automatic adjustment means from shaft 34 while manual adjustment is effected. As shown, lever 30 is rotated by thrust rod 26 and the increase in effective length between rod 26 and a crank 42 mounted on shaft 34 is utilized, by means of link 48, 44, 46, to rotate the crank and hence crank sleeve 50. A drive sleeve 52 is splined, with lost motion, to shaft 34 and a spring 58 is wound around both sleeves 50, 52 to serve as a clutch. The spring is wound in such a way that clockwise rotation of shaft 34 (as viewed from the right in Fig. 2) increases the frictional contact between spring and sleeves. A second clutch spring 60 on the opposite end of shaft 34 is wound in the opposite sense. In operation, rotation of the lever 30 causes rotation of crank arm 42 and sleeve 50; clutch spring 58 transmits this rotation to sleeve 52. If brake wear exceeds the amount of lost motion in the drive connection between sleeve 52 and shaft 34 the latter is rotated to effect adjustment; clutch spring 58 tightens and spring 60 slackens during such rotation. Spring 58 will nevertheless slip on sleeve 52 (which is of slightly smaller diameter than sleeve 50) at high torque levels so preventing over-adjustment. During the return stroke the slackening of spring 58 and tightening of spring 60 prevent rotation of shaft 34. Manual adjustment, in either sense, is effected by rotating the end 38 of shaft 34.

Title: Improvements in or relating to means for launching waves along a single conductor transmission line
IPC: H01P5/08
Filed: 1951-10-26
Abstract: 694,548. Wave-guides. STANDARD TELEPHONES & CABLES, Ltd. Oct. 26, 1951 [Nov. 18, 1950], No. 25099/51. Class 40 (viii). In arrangements for coupling a coaxial line and a single wire surface wave-guide, the inner conductor of the coaxial cable is gradually modified into the form of the wave-guide, and the outer conductor of the coaxial cable ends when the inner completely conforms with the surface line. Thus the mode of the wave in the coaxial line is gradually changed into the mode that surrounds the surface line. As shown in Fig. 2 the inner conductor 2 of the coaxial line is given a slow taper at its end surrounded by an expanding layer of insulation which continues until the dimensions of the surface line 3 are reached. In the construction shown in Fig. 3 the surface line 3 consists of a rod carrying integral metal discs, and, in the transition part the discs are of progressively increasing diameter as one proceeds from the coaxial line. In a further alternative, a spiral surface wave line is connected to the inner of the coaxial through a helix of progressivelychanging diameter.

Abstract: 293,682. Rainbow Light, Inc., (Assignees of Machlett, R. R.). July 9, 1937, [Convention date]. Vacuum tubes.-Luminous electric discharge tubes of high candle power containing neon or other rarefied gas and interior electrodes and applicable to beacons for aircraft are formed to provide several successive adjacent parallel paths for the positive column to give a concentrated source of light. The current is greater than 0.1 amp. and may be 10 amps. or more and the current per square mm. of crosssection of the positive column is greater than 1 milliamp. and may be 7 milliamps. Four concentric cylindrical paths for the positive column may be formed by tubes 2 - - 5, Fig. 1, with perforations 7 in the tube 4. Electrodes 8, 9, the latter of corrugated metal, are connected to contacts 10 on a heavy base 1. Adjacent paths separated only by walls of the tube are in this form in opposite directions with opposed magnetic fields; to increase the efficiency, such adjacent paths are preferably in the same direction, for example, an internal tube 14, Fig. 3, and an external tube 15 may be arranged as shown so that the portions of the positive column in the tube 14 and between the tubes 11, 14 are in the same direction and at some distance from the reversed portion in the tube 15. In another modification, the discharge passes up a central tube, down an outer annular space and then up an annular space between the central tube and the outer annular space.

Abstract: 360,531. Heavy current switches and switchgear structures. BIRKINSHAW, H., 1A, Longton Road, Irlams o' th' Height, near Manchester, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Aug. 22, 1930, No. 25167. [Class 38 (v).] Interlocked switches.- In a switchgear arrangement employing duplicate bus-bars the busbar selector switch 5, 6 is interlocked with the main circuit-breaker by means of a locking segment 11 secured to a crank arm 8 on the selector switch shaft 4. The locking segment passes through an aperture 12 in the front plate 2 of the structure and is provided on its bottom edge with notches 15, 16, 17 corresponding to the different switching positions, one of these notches being held normally in the lower side of the slot 12 by a spring 14. To operate the selector switch the locking segment 11 is raised by the handle 13 after which it is free to move within the opening or gate 12 so that the selector switch handle 1 may be moved from the position T shown corresponding to the connection of the " top " set of bus-bars to other alternative positions B or E corresponding to " bottom " bus-bar or earthing connections. The raising of the locking segment also raises a guided bar 19 the lower end of which rotates a pivoted lever 23 which in turn raises the circuit-breaker tripping bar 26 so ensuring that movement of the selecting switch occurs only after the circuit-breaker has been opened. At the end of the selector switch operation the locking segment is automatically locked in position by the spring 14 so allowing the circuit-breaker to be closed and freeing the circuit-breaker tripping gear for operation by the electrical trip mechanism contained within the casing 29. If desired, the gear may be locked when the selector switch is in the earthed position by a padlock, the bow of which is passed through a hole in a block 30 adjacent the non- pivoted end of the bar 26 which prevents the upward movement of the tripping bar.
