Abstract: A ball screw and nut assembly includes an improved ball return system designed to avoid abrupt directional changes in the recirculation path of ball bearings (22) from one end of a nut (30) to the other. A return tube (26′), secured to the nut (30), is formed in two sections, each having a major leg (40,42) and a minor leg (44,46). The ends (38,39) of respective major legs (40,42) are adapted to butt together along the centerline (a′-a′) of the bull screw nut (30). The minor legs (44,46), joined by elbows (43) to the major legs (40, 42), are disposed at angles equal to ninety degrees minus the helix angle of the ball screw and nut. The nut (30) contains transverse apertures (24′) at its respective ends to provide counterbores for support of the minor legs (44,46), each leg also extending tangentially for support of the minor legs (44,46), each leg also extending tangentially to the groove (14′) in the nut (30) at the location of its interface with the groove (14′). The result is a return tube system which avoids abrupt directional changes in the travel path of the balls.

Abstract: 7-(Diphenylmethyl)oxy-9a-methoxymitosane is a novel intermediate for conversion into 7-amino and 7-oxy-9a-methoxymitosanes and is also useful for inhibiting mammalian tumor growth. The compound is prepared by reacting 7-hydroxy-9a-methoxymitosane with diazodiphenylmethane. In a preferred reaction, the compound is prepared from mitomycin C via 7-hydroxy-9a-methoxymitosane without drying (water removal). The intermediate is advantageously converted to the very effective anti-tumor agent 7-[2-(4-nitrophenyldithio)ethylamino]-9a-methoxymitosane in unexpectedly high yields using a two step process where the first step constitutes conversion to 7-[2-(2-pyridyldithio) ethylamino]-9a-methoxymitosane or 7-[2-(3-nitro-2-pyridyldithio)ethylamino]-9a-methoxymitosane.

Abstract: In a run length limited digital signal of the d,k type, (d+m)-bit digital words are inserted at specific instants in a manner such that the signal thus obtained is a run length limited signal of the d,k' type, where k' is greater than or equal to k. This signal is then encoded in an aT precoder (8.1) and recorded on a magnetic record carrier (21). 
     Such (d+m)-bit digital words are inserted so that the current digital sum value in the output signal of the precoder shows a desired pattern as a function of time. For example, a pilot signal can be accommodated in the data stream of the precoder, which pilot signal can be detected during reproduction. From this detected pilot signal a control signal can be derived with which tracking can be realised.

Abstract: A postage meter resetting apparatus includes a stepper motor (61) as a first motive arrangement for turning the resetting shaft (85) of a mechanical postage meter (20), another stepper motor (69) as a second motive mechanism to enable or disable resetting by the first stepper motor. A lead screw (98), lead nut and linkage, driven by the second stepper motor, when resetting is authorized, moves an axially movable part of a coupling between the second stepper motor and the meter's axially movable resetting shaft, to bring the resetting gear (87) on the shaft into engagement with a gear (93) of the meter's descending register. An input to the first stepper motor (61), representing a variable amount of postage, effects turning of the resetting shaft (85) and the engaged gears by amounts corresponding to the desired variable amount of postage to be added to the meter's descending register (39). An encoder (64) coupled to the shaft of the first stepper motor provides an output indication of the amount that the shaft has turned. A CPU routine assures that the gear on the meter's resetting shaft has cleared a blocking pin (89) and engaged the descending register gear prior to resetting by the first stepper motor. Another CPU routine clears jams when it is detected that the shaft has not been turned the amount desired.

Abstract: A vacuum pickup system includes a transparent body portion 2 and plural air flow passageways 14. An indicator 6 is provided for each vacuum pickup device and contained within the air flow passageway intermediate a vacuum source and a vacuum pickup device 8. The position of the indicators within the flow passage is dependent upon the presence, or absence of a component on the end of the vacuum pickup device. With a component present on the pickup device, air flow through the passageway, due to the application of the vacuum source, is minimal and the indicator will be biased in a first direction. However, when a component is absent the pickup device substantial air flow occurs through the passageway, thereby biasing the indicator in a second direction. In this manner, an operator can visually inspect the monitor of the present invention to determine if each vacuum pickup device has a component affixed thereto.
