A clutch-actuating hydraulic slave or master cylinder comprises a metal, preferably seamless steel, tubing cylinder body one end of which is closed by a plug ported for fluid passage and the other end of which is open and has an external flange receiving a cover plate through which the piston of the cylinder slides. In the slave cylinder of Fig. 1 a plug 2 has a breather port 3 and a port 4 connected to a master cylinder. The plug is secured in an enlarged end of a cylinder body 1 against an internal shoulder thereof by punching the cylinder body well into plug peripheral recesses, by peening or grazing, or by a combination of welding or brazing and tube deformation. A piston 5 is recessed to receive one end of a rod 7 connected to the clutch release-bearing linkage. A cover plate 11 bolted to an external flange 9 has an aperture closely surrounding the piston 5, the, cylinder body having an enlargement 84 at its open, flanged, end to accommodate a lip seal 12. A boot 13 of synthetic rubber or other resilient material embraces the rod 7 and has a bead 14 engaging a groove 15 in a plate 16 also bolted to the flange 9. In the master cylinder of Fig. 2 a ported plug 19 is brazed in one end of a cylinder body 18 having a retaining lip 21. One end of a rod 24 connected to the clutch pedal or operating gear linkage is retained in a recess 23 of a piston 22 by a friction ring 25 thereby rendering a piston return spring in the cylinder bore (Fig. 3, not shown) unnecessary. A plate 29 bolted to a cylinder flange 27 comprises an outwardly extending sleeve 30 having a lip 31 limiting outward piston movement. The cylinder body has, at its open, flanged, end, an enlargement 26 which accommodates seats 32, 33 and a bearing bush 34 for the piston and is ported for connection, by a pipe 58, to a separate tank. In the master cylinder of Fig. 3 (not shown) at least one port in the cylinder body enlargement connects with a surrounding metal or synthetic, preferably clear or translucent, plastics tank secured to the cylinder body removably or permanently as, in the case of a metal tank, by soft soldering or bronzing. The synthetic plastics tank of Fig. 4 (not shown) has oppositely disposed tubular extensions, near its base, engaging, through seals, the periphery of the master cylinder body, and is axially located by the external flange of the cylinder body and by a retaining ring engaging a groove in the closure plug or cylinder body periphery.

Abstract: 1,133,970. Directional signalling apparatus. ESSEX WIRE CORP. 14 Oct., 1966 [15 June, 1966], No. 46013/66. Heading G4Q. [Also in Division H1] Direction signalling apparatus comprising an actuating member 31 mounted on a support member 3 on the vehicle's steering column for movement from a neutral position to one of two latched operating positions from which it is released by operation of the steering mechanism and means for arresting the actuating member intermediate the neutral and latched position from which intermediate position the actuating member can be moved by the application of sufficient force to the latched position or spring returned to the neutral position. The direction signals are operated in both intermediate and latched position, the first position being used for overtaking or lane change and the second for turning movements. The actuating member (bottom plan view, Fig. 5) is driven by shaft 13 and includes supply terminals 37, 38 and switch members 35, 36 which co-operate with fixed contacts 8-11 on the support member, Fig. 2, resilient latching arms 50, 51 which co-operate with latching means 20, 21 on the support member, resilient latch releasing arms 60, 61 which co-operate with the arms 2 on the steering shaft 1 and a rib 64 which co-operates with a flat return spring 16 on the support member. On movement of the actuating member, e.g. to the left the depending portion 54 of the resilient latch arm 50 engages and rides along the sloping portion 22 of the latch means 20 until arrested by stop 23. Because of the resiliency of the latch arm the application of a further force to the actuating member moves the arm to the latched position in which portion 54 engages behind the part 24 of the latch means. In the arrested and latched position the associated signalling circuit is energized. The actuating member is returned to neutral from the arrested position by spring 16 and from the latched position by the same spring when latch release arm 60, engaged by a cam 2 as the steering mechanism is returned to normal after a turn, encounters the sloping portion 55 of the latch arm and releases it.

Abstract: 1,044,834. Controlling aircraft. SHORT BROTHERS & HARLAND Ltd. Dec. 21, 1962 [Dec. 27, 1961], No. 46305/61. Heading B7G. [Also in Division G3] The gain of a servo-system controlling the attitude of an aircraft about an axis is automatically controlled in dependence on a comparison between angular acceleration of the aircraft about the axis and the turning effect applied to the aircraft. The pitch attitude of a VTOL aircraft is automatically controlled by applying electrical signals from pick-offs associated with an attitude gyro 17 and a rate gyro 18 to amplifier 15 energizing a torque motor 14. Torque motor 14 controls an hydraulic servomotor 12 which actuates an elevator control surface 10 and a swivelling jet 11 to restore the aircraft to an attitude determined by electrical signals applied to amplifier 15 from a pick-off associated with a manuallyoperated control column 16. Feedback signals dependent on the position of the elevators and jet are derived by a pick-off 21 and applied to the input of amplifier 15 through a potentiometer 23 which is adjusted by an actuator 27 in dependence on angular acceleration of the craft about the pitch axis as measured by an accelerometer 25, so that the gain of the servomotor system is varied inversely as the response of the aircraft to elevator adjustment. Fixed feedback is also applied from the output of torque motor 14 to the input of amplifier 15. A modification involving rate of change of acceleration is referred to.
