Abstract: 756,003. Indicating-apparatus. SHORT BROS. & HARLAND, Ltd. June 9, 1955 [June 9, 1954], No. 16944/54. Class 106 (4). A scaling unit for measuring the position of a discontinuity in relation to a straight-line trace on the screen of a cathode-ray tube, comprises at least one cylindrical scale 14 which is moved axially and also rotationally in relation to a support 10 and has on its surface graduations in the form of helical lines of progressively increasing helix angle, the zero graduation having a helix angle of zero degrees, the maximum graduation having the maximum helix angle and the intermediate graduations having helix angles proportional to their distance from the zero graduation. In operation, a cursor 16 carried by a block 15 on a lead screw 13 is registered with the left-hand end of a trace viewed through a window 12 by turning the screw 13 by means of knob 23. A screw 20 is then turned by means of knob 25 and co-operates with a sleeve 20, on which the scale 14 is rotatable, to shift the zero graduation into register with an index 18 in line with the cursor 16, the sleeve 20 being prevented from turning. by pins 24. The cursor is then registered with the right-hand end of the trace and a knob 19 secured to the scale 14 is turned till the maximum graduation registers with the index 18, a nut 21 and a collar preventing axial movement. With the scale thus set the cursor is registered with the discontinuity in the trace and its position read off the scale by means of the index 18. A second scale 14 is allotted to an alternative signal producing a trace on the screen. Specification 752,853 is referred to.

Abstract: 968,922. Regulating vehicle brakes. FABBRICA ITALIANA MAGNETI MARELLI S.p.A. May 8, 1962 [May 9, 1961], No. 17587/62. Heading F2E. Apparatus for regulating the action of vehicle brakes comprises a brake-operating member K, regulating means operable, after the brakeoperating member has travelled a predetermined distance, to oppose further movement of the brake operating member until a force is applied to the member K sufficient to overcome the action of the regulating means and manual control means operable to render the regulating means operative or inoperative. As shown the apparatus is coupled into the braking installation by movement of a driver operated lever 50 to rotate a cam 48 which displaces a tubular element 44 towards a spring-loaded valve 34 so as to close communication between chamber 26 and discharge aperture 42. Further movement of the cam 48 lifts the valve 34 from its seat so that compressed air in chamber 30 passes into a cylinder 10. At the same time a switch 52 is closed and the lamp 54 lights to indicate to the driver that the brake regulating device is in operation. Compressed air entering the cylinder 10 displaces piston 14 upwardly against the action of spring 22 thus engaging the push rod 18 with the braking pedal K in order to oppose further movement thereof, after a certain displacement of the pedal K, thereby limiting the braking action. In a modification the piston rod 16 is hollow and acts as a cylinder in which a piston carrying the push rod 18 moves. The piston is actuated by a master cylinder device having a lever controlled by the driver and which can be held in a number of positions, each position corresponding to a different position assumed by the push rod 18. The brake pedal opposing force may be provided by a spring.
