Abstract: A disposable flexible plastic enema nozzle with self-adhesive securing means for convenient attachment to the patient's buttocks is disclosed. The securing means comprises an annular positioning collar disposed about the enema tip or tube. The positioning collar has an elongated self-adhesive plastic sheet with easily removable protective tabs covering the adhesive. In one embodiment of the invention the positioning collar is fixed near the distal end of the tube, while in another embodiment the positioning collar is slidable along the tube for adjusting the insertion length of the tube. The invention is particularly applicable to diagnostic enema procedures, such as barium enema for radiological examination, performed on infants, small children, the infirm and the elderly.

Abstract: A hand held carrier for transporting garments on clothes hangers is disclosed. The carrier is a single structure comprising a contoured handle, a textured post and a shield that houses a hanger port. Within the hanger port, hooks are compressed or bundled while being supported on a semi-circular support bar that orients the hangers substantially parallel to the user's arm when carried. The shielded hanger port serves to protect the user's hand from contact with the tips of the hanger hooks and deters accidental snagging and disengagement. The carrier includes a thumb hook receiver on the underside of the handle for supporting the device on a conventional automobile interior hook. The carrier also includes a centering notch to stabilize the device during loading and unloading when temporarily placed on a clothes rod.

Abstract: An electromagnet consists of two essentially symmetrically designed magnetizable E-shaped yoke halves each embraced by a coil. The facing pole ends of the yoke halves form three aligned operating gaps. Between the operating gaps a tongue-shaped ram is arranged which is shiftable in the direction of the line of alignment of the operating gaps. The cross-section of the ram is adapted to the area of the operating gaps. The ram comprises cuboid-shaped armature bars of magnetizable material. The armature bars are geometrically designed in such a manner that their volume is on the order of magnitude of the operating gap volume. In the original position of the ram the armature bars are essentially positioned in front of the operating gaps of the electromagnet. Upon excitation of the electromagnet, the armature bars are pulled into its operating gaps, being accelerated in the process.The windings of the coils exciting the yoke halves are essentially positioned between the E-legs of the yoke halves.

Abstract: A bandgap reference voltage generator consists of a plurality of transistors with the same geometry. This circuit provides a stable temperature-compensated low reference voltage on the order of two volts.

Abstract: A fuser roll apparatus in a toner fixing station associated with an electrophotographic or xerographic device for fixing a toner image onto a copy sheet by the application of heat and pressure. The fusing apparatus includes a pair of fuser rollers and a linkage mechanism coupling a control cam and the fuser rollers. An electromechanically operated latch, in the form of a solenoid, is interposed in the linkage mechanism coupling the control cam and fuser rollers. So long as the solenoid is energized, the opening of the rollers is controlled solely by the rotation of the cam. If the solenoid is deenergized however, the rollers are maintained in an open position. Thereafter, until the solenoid is again energized, the rollers remain open and are unaffected by rotational movement of the cam.
