Abstract: 1324073 Indicating track connection FRANZ PLASSER BAHNBAUMASCHINEN INDUSTRIE GmbH 14 Sept 1970 [16 Sept 1969] 45592/69 Heading B7N [Also in Divisions G1 and G4] In a device for measuring the difference in height of rails, of a railway, a level sensing device is attached to a probe, mounted on a rail vehicle; the probe may in fact be the vehicle wheels. This produces a signal representing tilt, which signal is stored and compared with a second similar signal produced at a later time. The level sensing device may be a gyroscope 12, Fig. 2a, whose output shaft drives an encoder 13, so that the shaft position gives a measure of tilt. Alternatively the gyroscopes may give an analogue output which is fed to an analogue to digital converter. Another embodiment uses a pendulum which is corrected for the effects of centrifugal force, (Fig. 2c), and fixed to shaft 32 of encoder 30 which is attached to a housing on the vehicle. To correct the effect due to centrifugal force the pendulum carries an accelerometer whose output is fed via amplifier 33 to servo motor 34 which applies a correcting torque to shaft 32. In another embodiment the tilt of the vehicles axles is sensed by an electro-level 24, Fig. 2b. The output of the electro-level 24 together with the output of an accelerometer 28 (to compensate for centrifugal force on the bubble) is fed to unit 27 which feeds an output to analogue to digital converter 29. The digital output of the encoder or analogue to digital converter, which may be either gray code or binary code, representing the axle twist on the probe or vehicle wheels, is fed to sample and hold device 14 which is periodically enabled by a system 15 generating a pulse every time the vehicle travels a unit distance. The output of 14 passes the unit 15 which produces an output representative of the difference in rail heights. This output passes via amplifier 17 to a tape, punch or magnetic recorder 18, or directly to a computer. The output of unit 15 is also fed to a shift register 19. The shift register 19 has outputs at its X, Y, and Z stages leading to summing circuit 20, 21 and 22. These summing circuits also receive the current output from unit 16. Thus the outputs of circuits 20, 21 and 22 represent the relative axle twist for vehicles with wheel bases corresponding to X-1, Y-1 and Y-1 units.

Abstract: 1350330 Feeding cigarettes between making and packing machines AMF Inc 19 Sept 1972 43257/72 Heading B8A Cigarettes fed from the output 34 of a making machine, to the input of a packing machine may, if the demand of the packing machine drops, feed the cigarettes into radial slots S of a storage drum 1. The cigarettes are normally fed by a rotary conveyer 3 to one of three endless belt conveyers 104, 105, 106, forming part of the input of the packing machine. The frame of the conveyer 3 has segmentally extending suction slots 103, 203, 303, 403, and 503. By controlling the suction to these slots, cigarettes may be fed to, retained on, or discharged from, the conveyer, as determined by photo-electric sensors (not shown). Similar suction segments 102, 202, are provided on a feed wheel 2 for effecting the transfer of cigarettes between the conveyer 3 and the slots S of the drum 1. Further similar suction slots 204, 205, 206, are provided respectively on feed wheels of the conveyers 4, 5, and 6. The depth of each slot S is progressively increased with each revolution of the drum 1. This is achieved by the movement of a member 9 which forms the base of the slot S. The member 9 is carried by a bracket 10 which is in threaded engagement with a disc 11. The latter normally rotates with the drum but by suitable operation of clutches 30, 31, and a brake 32, which are mounted in the drives to the drive pinion 15 of the drum, and the drive pinion 19 of the disc 11, the latter is made to move the member 9 radially inwards. The member 9 is moved a distance equal to the diameter of a cigarette, for each rotation of the drum 1. Similarly by further suitable operation of the clutches 30, 31, and brake 32, the member 9 may be made to move radially outwards when the drum is feeding cigarettes to the packing machine.
