Abstract: 1,108,773. Fluid-pressure servomotor systems. VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY INSTITUTE SELSKOKHOZYAISTVENNOGO MASHINOSTROENIA. April 15, 1965, No. 16394/65. Heading G3P.  An agricultural separating unit (not shown), e. g. forming part of a potato harvester, is actuated by a variable speed drive 11 and discharges on to a belt conveyor 3, the discharge rate being controlled by a chain-driven roller 1 mounted on a frame supported by a cable 4 connected to a two-arm lever 5. The lever is connected to the plunger 12 of a control valve 7 via a cable 6, housing 37 and spring 36, the control valve controlling the operation of a servomotor 10 connected via a lever to the variable speed drive. The servomotor 10 also carries an electric contact 18 which co-operates with stationary contacts 19 or 20 to light indicators 22 or 23 to indicate whether the speed of the separator is being increased or decreased. In operation, the roller, which is spring-loaded at 34 and connected to a damper 2, controls the thickness of material on the conveyor 3. The controlled thickness may be adjusted by a lever 15 connected with an extension of cable 4, the extension being enclosed in a sheath 17 so that adjustment of the lever distorts the sheath to vary the position of the control valve to thereby vary the position of the roller corresponding to the neutral position of the control valve. In alternative embodiments (not shown) separation is controlled by variable jigging mechanisms.

Title: Punch mechanism verifying apparatus
IPC: B26F1/02
Filed: 1962-04-30
Abstract: 937,098. Selective punching machines. SOROBAN ENGINEERING Inc. April 30, 1962 [Sept. 11, 1961], No. 16448/62. Class 31 (2). [Also in Group XXII] Means for detecting whether or not a punch 31 has been operated comprises at least one recess in the punch, magnetic means for establishing a magnetic flux through the punch and in a path including an air gap provided by the recess and means for detecting variations in the magnetic flux resulting from movement of the recess and therefore of the punch. The invention is described as applied to a machine in which any of a set of punches 31 may be moved upwardly in relation to an intermittentlyadvanced tape or card. A permanent magnet 54 is supported by a plate 52 from the lower part of the guide block 49 for the set of punches and carries on its upper face a plate 57 of magnetically-permeable material having a series of fingers 58, each of which extends inwardly through the guide block for coaction with either of two recesses 62, 63 in the side of the corresponding punch. Depending upon whether a punch is in its lower unactuated position so that the deep recess 62 is opposite the finger 58 or in its upper actuated position in which the less deep recess 63 is opposite the finger, different magnetic reluctances are set up through the lower portion 56 of the block 49, plate 52, punch, air gap at the recess and finger 58 and so establish different signals in a coil 60 surrounding the finger; the same effect may be produced by using a single recess. Thus, each operation of a punch results in two distinct signals in the corresponding coil 60 and these may be applied in a circuit which is used to determine whether or not the correct punch has been operated and there has been a correct feed advance of the tape to prevent over-punching; the circuit may be arranged to give a visual or audible indication of the position or shut-down the machine upon incorrect operation. In one such circuit for a machine employing a set of punches arranged to be operated according to a prescribed code, two groups of relays are respectively set according to the code of the punches selected for each punching operation and the punches actually operated as shown by the signals from the coils 60, and a further relay is suitably set by a signal indicating correct advance of the tape for the punching operation. If the settings of the two groups of relays do not correspond, indicating incorrect punching, or if the other relay fails to indicate correct tape advance, a stop signal is transmitted. If desired, comparison between the two groups of relays may be made by the operator or automatic circuits which, in the event of incorrect punching, effect over-punching to indicate the fault, followed by re-application of the correct code and normal punching. Specifications 898,721 and 898,722 are referred to.
