Title: Gear change with auxiliary pneumatic servocontrol
IPC: F16H63/20
Filed: 1958-05-06
Abstract: 889,127. Change-speed control. FABBRICA ITALIANA MAGNETI MARELLI S.p.A. May 6, 1958 [May 6, 1957; Nov. 30, 1957], No. 14442/58. Class 80 (2). [Also in Group XXIX] In a gear shift for vehicles &c., wherein manual rotational and axial movement of a lever-operated rod A respectively effects, through arms 1, 3, 2, axial (cross-shift) and rotational (gear establishment) movement of a rod B, the said gear establishment only is assisted by a floating-lever, follow-up, pneumatic servomotor, comprising valves 6, 7 receiving compressed-air at A.C. and feeding a double-acting operating cylinder 12. When the rod A is axially moved, in either direction, e.g. in the direction f1, with the crossshift position M3, M4 predetermined, the arm 3 is rotated about a hinge 5 initially held stationary by the resistance of the rod B, to open a valve 11 feeding the end D of an operating cylinder 12, which moves a piston 15 rotating the arm 2 and the rod B in the direction f3 to establish a gear M3. The resultant rotation of the hinge 5 tends to close the valve 11 therefore pilot movement of the arm 3 by the rod A must be maintained until establishment is completed. In the event of pneumatic failure manual gear establishment is possible. Joints G1, G2 permit the removal or installation of the servomotor as a unit in an existing gear-casing. As shown, the rod B is centred at the M3, M4 cross-shift position by a spring. In Fig. 2, not shown, means to prevent unintentional servo-action by movement influenced by the inertia of the control members and the support elasticity comprises a prismatic coupling between the rod A and the arm 1 allowing spring-opposed axial lost-motion only. The female element fast on the arm 1 has three circumferential notches for engagement by a locating detent.

Title: Improvements in or relating to ball point writing implements
IPC: B43K7/12
Filed: 1957-05-10
Abstract: 812,516. Reservoir pens. MEIER, G. May 10, 1957 [May 22, 1956], No. 14931/57. Class 146(3) A ball-point pen having an exchangeable writing unit 31, comprises a retractable protective sleeve 33, which has a front opening corresponding to the diameter of the writing point, which protective sleeve extends between the barrel and a guide sleeve 29 receiving the writing unit and limiting its advance, the writing unit being spring biased so that pressure on the writing point moves it back with the protective sleeve 33 into the retracted position of the latter whilst on removal of the pressure the writing unit advances again into its writing position. As shown the barrel is formed in two parts 27, 28 which are screwed together the part 27 having a rear portion slotted at 35 which extends beyond the screw threads and into the part 28. The guide sleeve 29 has an enlarged rear end which is engaged in the rear portion of the barrel part 27. The ball-point writing unit 31 is slidable in the guide sleeve and biased forwards by a spring 30 acting between a screw cap 32 in the end of the guide sleeve and a flanged sleeve at the rear end of the unit so that a collar 38 on the unit abuts against the inturned front end of the guide sleeve. The protective sleeve 33 has radial lugs 34 which project through the slots 35 in the rear end of part 27. A plunger 37 is slidable in the rear barrel part 28 and has a tubular extension which surrounds the rear end of the part 27 and engages the lugs 34. Thus when the sleeve 33 is retracted, pressure on the plunger will push it forward to conceal the writing point. To expose the point the front end of the sleeve is pressed against a surface and forced backwards, the writing unit 31 also being forced backwards: on releasing the front end from the surface the sleeve remains in its rearward position while the unit is urged forward by the spring 30 until the collar 38 again abuts against the front end of the guide sleeve 29 and the writing point projects through the aperture in the sleeve 33. In a modification the protective sleeve has a radial lug which projects through a slot in the barrel for advancing the sleeve.

IPC: H03K3/08
Filed: 1956-05-14
Abstract: 803,597. Pulse generator circuits. NAGARD, Ltd. May 9, 1957 [May 14, 1956], No. 14952/56. Class 40 (6). A multivibrator comprises a pair of discharge tubes having their anodes and control grids reciprocally coupled via capacitors and in which the grid leaks are connected via diodes to a fixed potential and the cathodes are connected via a common resistor to a more negative fixed potential. The value of the cathode resistor limits the current passed by each tube to less than its full emission current and in this way the frequency stability of the multivibrator is rendered less dependent on the tube characteristics. The Figure shows a multivibrator in which the grid leaks of tubes V1, V2 are returned via diodes D1, D2 to earth and the cathodes via common resistor R5 to a potential of for example - 150 volts. The cathodes follow closely the grid voltage of the conducting tubes and are effectively earthed so that the current in the resistor R5 can therefore be precisely controlled and the amplitude of the negative voltage excursion of the tube anode can be selected by a suitable anode resistor. Since resistor R5 limits the current through either tube to less than the full emission current of its cathode the negative voltage excursions of the anodes are almost independent of the tube characteristics and the output waveforms at the anode will be more nearly square and of constant amplitude.
