Abstract: 883,372. Printing-machines. RITZERFELD, W., and RITZERFELD, G. Nov. 17, 1959 [Nov. 26, 1958], No. 38906/59. Class 100(2) Rotary machines; tripping mechanisms A rotary duplicating machine comprises a first printing drum having means for attaching thereto a lithographic master sheet with a mirror-script and arranged adjacent a counter pressure roller of approximately the same size and having means for attaching thereto a copy sheet, said counter pressure roller being arranged adjacent a second printing drum having means for attaching thereto a lithographic master sheet with a directly readable script, the arrangement being such that, prior to the attachment of the copy sheet the master sheet on the second drum prints a copyable mirror-script on to the counter pressure roller whereupon, after the attachment of the copy sheet, the master sheet on the first drum prints on one surface of the copy sheet and the mirrorscript on the counter pressure roller prints a copy on the other surface of the copy sheet. Copysheets 1, Fig. 1, are fed to grippers 30 on the counter pressure roller 15, and passed between the roller and a drum 16 carrying a mirror-script master 19, then being delivered by a suction device 151 oscillated by a rotary member 152 to a table 34. The master 112 on the drum 111 has previously printed on to the resilient covering of the roller 15. If only one side of the copy sheet is to be printed on the drum 111 is moved away from the roller by turning an eccentric 115. In another form, Fig. 2, sheets 1 are fed every second revolution of the drums 16, 54 to the roller 15. A magnet 161 controlled by the drum revolutions causes a plate 158 pivoted on an eccentric 160 to swing during successive revolutions of the drum alternately against stops 164, 165, thereby bringing the roller 15 alternately into contact with the drum 54 to receive its mirror-script copy on the non-sheet feed cycle, and with the drum 16 to print on both sides of the copy sheet. In both forms, if a copy sheet is not correctly fed, a photo-electric cell 8 operates a control motor 10 actuating a cam 149 or 159 to retract the roller.

To prevent undesirable self-disengagement under load, the working faces of the teeth, e.g. 23, of either one of two axially engageable and disengageable toothed members such as two external gears, an internal and an external gear, or an internally and an externally splined member, e.g. of the motor vehicle change-speed gear positive clutch shown, have recesses 25 to receive therein the entire working faces 33 of the teeth 16, of the other member such that in the engaged position each of the teeth 16 is, under normal load, in edge-to-surface contact with a ramp 29 of the corresponding recess 25 with its corner 30, and the working face 33 is inclined at an angle D to the centre line of the tooth 16 and at angle E to the ramp 29 with the angle D selected such that on occurrence of a sudden impact load the clearance provided by the angle E substantially closes to produce momentary substantially surface-to-surface contact, tooth deflection remaining within the elastic limit so that permanent set does not result. With wear, the line contacts between the teeth increase to limited area contacts. As shown, the teeth 23 are internal clutch teeth of a slidable fork-actuated sleeve constantly meshing external teeth of a shaft collar and selectively movable axially into mesh with the teeth 16 which are external clutch teeth of a freely rotatable gear. In the engaged position the sleeve teeth 16 may also contact relatively steep ramps 31 of the recesses 25, with their corner surfaces 32, the ends 18 of the sleeve teeth 23 being clear of the adjacent gear wall 28.

Filed: 1972-08-22
Abstract: 1406663 Substation circuits STANDARD TELEPHONES & CABLES Ltd 16 Aug 1973 [22 Aug 1972] 39083/72 Headings H4K and H4R A telephone subset circuit is powered over a two-wire line L1, L2 via a voltage regulator VR and is responsive to line current to automatically adjust the gains of microphase amplifier TME and receiver amplifier RME to effectively compensate for line length. The voltage regulator VR provides a stabilized 3V supply over lines PL for each circuit block and includes a 10 ohm resistor effectively connected across the line. The voltage drop across the resistor is detected (Fig. 6, not shown) as an indication of line current to increase the gains of TME and RME for low current and vice versa by varying the conductivity of bleed diodes. Microphone signals pass through an age amplifier and amplifier stages ITA, TME, OTA direct to terminal 16 and via terminal 9 and external RC circuit to cancel side-tone whilst some side-tone is fed to RME from terminal 9. Incoming line signals are fed to RME via terminals 16, 9 and the RC circuit. The gains are reduced for the longest line, to prevent the risk of overload, by self-insertion of a transistor in the line current detector circuit. The gain of TME is also increased by TAD when the microphone signal indicates a speech level above ambient room noise. The age amplifier is controlled by a detector GAD including four transistors in class C forming a peak detector serving to discharge a capacitor controlling a current generator in the age circuit. The charge time constant is three times the discharge time constant.
