Abstract: 1350005 Registering print rollers HARRISINTERTYPE CORP 8 Nov 1971 [23 Nov 1970] 51797/71 Heading G4H [Also in Division B6] Apparatus for positioning any one of a plurality of print rollers with regard to their lateral position with respect to a web and their circumferential position thereto comprises a counter, manually presettable to a desired adjustment distance, and a plurality of manually operable selector switches one each for advance and retard in both lateral and circumferential directions for each roller, operation of the desired one of the switches causing the corresponding roller to be moved by a distance analogous to the number set in the counter. Operation of a switch to cause a circumferential adjustment operates a series of relays which cause corresponding gates to pass shaped D.C. pulses to operate a stepping motor and simultaneously after frequency division to decrement the counter until zero is reached when the gates are disabled by resetting of the relays. For a lateral adjustment, the corresponding switch causes in a similar manner A.C. to be applied to a synchronous motor. Owing to mechanical interaction in the apparatus, lateral adjustment of a roller will cause movement in the circumferential direction and this is compensated by the switching of a lower frequency oscillator to apply pulses to the stepping motor to decrement the counter, the movement again being terminated when the counter reaches zero. Prior to the adjusting process, the roller is returned to the middle of its adjusting range automatically after activation of a further switch, this process being controlled by a further set of relays and by switches mechanically actuable by the roller to indicate which side of the midpoint the roller is positioned.

Abstract: 1,211,741. Fluid-pressure servomotor systems. HOERBIGER VENTILWERKE A.G. Nov.21, 1967 [Nov.24, 1966], No.52857/67. Heading G3P. A multi-stage compressor, e.g. a piston-type, has stages I-IV and unloading is effected at a given receiver pressure by control unit R 1  which lifts the suction valves 7 of the first stage. The consequent fall in the delivery pressure of this stage is transmitted via line 5 both directly and through restrictor 19 to actuate the diaphragm of a leak-off relay R 2 . The latter causes valve 15 to open to by-pass air from the final stage to the line between stages I and II. When the control pressure on relay R 2  has equalized through restriction R 2 , the by-pass valve 15 closes. In this way, the time taken for the unloading sequence to affect the delivery to the receiver is reduced. In modifications, the first stage is unloaded by throttling the suction line or by-passing that stage and the final stage is unloaded by bleeding to atmosphere, by lifting the suction valves or by by-passing that stage only. The control may maintain a constant mass flow-rate.
