Abstract: 1,127,072. Fluid-pressure brakes. AUTOMOTIVE PRODUCTS CO. Ltd. 14 Sept., 1966 [17 Sept., 1965], No. 39754/65. Heading F2F. An hydraulic braking system for aroad vehicle, wherein there is provided a compressed-air servo, and which may be associated with a compressed-air trailer braking system, comprises dual hydraulic circuits 52, 61 supplying separate chambers 14, 15 of equal or approximately equal area in each of a set of brake cylinders 5-8, the circuits being fed by primary and secondary chambers 39, 48 of a tandem master cylinder 32, the primary piston 40 of which is actuated by a pair of air actuators 30, 31, or by a doublediaphragm actuator (Fig. 3, not shown), having a common output rod-34, control of the actuator(s) being by separate valves 64, .65 controlled by the pressure developed in a pedaloperated master cylinder 17 having separate reservoirs 26, 27 for the two hydraulic circuits, the latter supplying the circuit fed by the primary chamber 39 while the former supplies the circuit fed by the secondary chamber 48 via chamber 24 of the pedal-operated master cylinder. In the diagrammaticallyillustrated embodiment of Fig: 1, the pressure developed-in the pedal-operated master cylinder acts on a secondary piston 22 which in turn acts via a balance beam 76 on the stems 72 of the valves 64, 65, one of which can also be operated manually by handbrake lever 109. In the modification of Fig. 6, however, reaction pistons 134, 135 each comprising an hydraulic piston element 136 and a pneumatic piston element 137 exposed to hydraulic pressure in the chamber 24 and to pneumatic pressure delivered by the associated valve, respectively, are each provided with one valve seat 138 of a lapping valve assembly 138, 139, 141, rods 147 connected at their outer ends to a handbrake linkage engaging the pistons so that simultaneous manual application of the valves can also be effected. In both embodiments direct mechanical application of the valves can be effected in the event of failure of the hydraulic circuit including chamber 24, by contact of an extension rod 143 of the pedal-operated piston 19 engaging the secondary piston 22 or a bridging plate 144 contacting the reaction pistons 134, 135, respectively.

Title: Improvements in or relating to control systems
Inventor: TINKLER KENNETH
IPC: B23Q35/121
Filed: 1965-09-18
Abstract: 1,120,962. Copying. TELEHOIST Ltd. 19 Sept., 1966 [18 Sept., 1965], No. 39901/65. Headings B3K and B3T. [Also in Division G3] In a pattern-controlled machine tool, such as a lathe, milling machine, profile grinder or polisher or profile sheet cutter, the tool is controlled in accordance with both the position and velocity of the pattern follower, thereby reducing the velocity error of the tool. In Fig. 2, the workpiece 22 and pattern 3 are rotated by hydraulic motor 18 via gearbox 19. At the start of a machining cycle, hydraulic fluid from line 13 is directed by control unit 17 to line 23 to retract piston 25 to disengage locking pin 28 from gearbox shaft 29. Solenoid 30 is then energized to supply ram 9 via restriction 35. The ram cylinder moves leftwards to cause tool-holder 1 to approach the workpiece. This movement of the ram cylinder also causes movement of the housing of valve 8 so that pattern follower 2 is caused to approach the pattern and the movement ceases when the tool holder reaches the position defining the start of machining. At this point, a micro-switch (36) is operated by the follower and causes both the energization of solenoid 37 to bypass restriction 35 and the supply of fluid to motor 18. Prior to the end of machining, the follower engages a second microswitch (39) to cut off the supply to motor 18 and engage locking pin 28 with shaft 29. Solenoid 30 is then de-energized and valve 12 is opened for an interval to retract the tool holder. During machining, valve 8 is controlled by follower 2 and follow-up is achieved by connecting ram 9 to the housing of valve 8. The signal representing the velocity of the follower is generated by a tachometer 6, driven through rack-and-pinion gearing, and fed to valve 12. In Fig. 3 the feeler 2 is pivotable with body 54 about axis Y-Y and its movement is transmitted to valve 8 via a leaf-spring (68), carried by nut 69, and probe 65 pivotable about axis Z-Z. A spring 64 biases body 54 so that feeler 2 contacts the pattern. The feeler is retained on body 54 by a spring detent (63) which urges the feeler upwardly so that a pin (62) thereon engages in a notch (60) in a yoke (59) connected to body 54. In the diagrammatic system of Fig. 6, not shown, the position and velocity signals from the follower are received by a mixing amplifier (102) which controls the ram (9) via an electrohydraulic servo-valve (103). The movement of the tool-holder is fed back to the linkage of the follower by an electrical position transducer (100).

Abstract: 1446734 Welder's eyeshield GOTAVERKEN AB 28 Aug 1973 [4 Sept 1972 13 March 1973] 40459/73 Heading G2J A welder's protecting eye-shield e.g. in the form of goggles or in one piece comprises a multi-layer interference filter which transmits in a narrow band covering the wavelength of yellow sodium light and, preferably, in at least one further narrow band in the range 570-600 mm. The transmission bands lie in dips in the intensity distribution of light emitted by the welding process and at the same wavelength as the emission lines of the discharge lamps used to illuminate the workpiece. Thus the shield protects while welding and yet allows the welder to see about himself clearly without removing the shield while not welding. The eye-shield may take the form of partspherical filters mounted in a frame so that, when worn, the centre of curvature of each filter lies at the centre of the corresponding eye. Alternatively a single element may be used either of simple curvature or shaped to have a convexity in a horizontal and a vertical plane. The filter does not transmit I.R. or U.V.
