    • A stepper motor (10 or 80) includes a stator (12) with magnetic poles (54) extending radially outward from a central core (56) to form segments of an outer stator surface, an armature ring (48) fitting loosely over the stator, and a rotor (14) with a drive plate (36) rotationally driven by rollers (52) extending from the armature ring into apertures in the drive plate. Current is applied, according to a sequence, through coils (58) surrounding each magnetic pole, so that the armature ring, being sequentially attracted to adjacent magnetic poles, moves around the stator with a modified orbital motion. This modified orbital motion is a combination of an orbital motion in which the ring is translated around a circular path, and a rotational motion. The stepper motor may also include a stationary cam plate (82) with a number of peripheral notches (86), into which the rollers (52) are moved individually by the orbital motion.

    • A coupling, which may be an ostomy coupling but could be any kind of tube or pipe coupling, includes a first coupling member 10 and a second coupling member 30 which are mutually interengageable and which surround an orifice 70. The coupling also includes a resilient split ring 50 which encircles the two coupling members and has a handle member 51 which can be manipulated to cause the split ring to be deformed. This causes the radially-inwardly extending tabs 52 on the ring to be shifted between respective first positions in which the split ring is undeformed and the tabs lock the two coupling members together and respective second positions in which the split ring is deformed in such a way as to shift the tabs radially outwardly to positions where they permit separation of the two coupling members.
      The split ring is desirably made of a relatively rigid but springy plastics material, for example an acetal resin. The tabs carried by it are provided with curved or angled ramp surfaces which, when the ring is deformed by a force tending to rotate it relative to the coupling members, cause the tabs to be withdrawn from slots in one of the coupling members so permitting the two coupling members to be separated.

    • A self-adjusting motor positioning system comprises a motor 24 including a shaft extending therefrom, a disc 20 coupled to the motor shaft and having at least first and second notches, 26, 28; rotating apparatus coupled to the motor shaft whereby the rotating apparatus is intermittently driven by the motor, a sensor 31 adjacent the disc for detecting the first and second notches, and a control processor 30 coupled to the sensor and the motor for receiving detection signals from the sensor and for turning the motor on and off. The control processor includes memory for storing a time delay count representing a time delay for the control processor to turn off the motor after the second notch is detected by the sensor. The rotating apparatus includes a starting position from which the rotating apparatus begins. The first notch in the disc corresponds to the starting position of the rotating apparatus. The control processor turns the motor off when the time delay expires after the sensor detects the second notch. The sensor senses for the first notch as the motor coasts to a stop, and the control processor adjusts the time delay count if the first notch is not detected when the disc is at a complete stop.

    • A tube coupling locking assembly (10) for preventing undesired loosening of a make-up coupling includes a cooperating pair of rigid lock members (26,28) that encircle about a coupling nut (18) with one of the lock members (26,28) having an end connected to a second cooperating coupling nut (16) or the body of an associated fluid device. The cooperating lock members (26,28) are arranged to prevent relative rotation between the encircled coupling nut (18) and the cooperating coupling nut (16) or associated fluid device.
