Abstract: A panel-like lid is secured to a receptacle by a pintle for pivotal movement between a closed position and an open position about an axis whereby the lid remains horizontal at all times. In the closed position, a continuous groove in the underside of the lid matingly receives a bead upstanding from the upper edge of the sidewall of the receptacle. A compression spring encircling the pintle normally urges the lid downwardly against the receptacle. In response to movement from the closed position toward the open position, the lid is cammed upwardly to disengage the groove from the bead.
Abstract: A connector for medical devices includes a housing having an interlock member and two types of luer nuts.

Abstract: A button applicator for caulking one button element to another button element through a fabric piece, using a punch and a die. When a button element having a different caulking pressure is applied, any adjusting for a resilient force supporting the die is unnecessary. According to a preferred embodiment, a first spring and a second spring are provided between a spring-positioning member and a spring-supporting member so that the first spring is encircled by the second spring and that the top of the first spring is higher than the top of the second spring by a predetermined gap. The movement of the die is conveyed to the springs through a shaft provided between the die and the spring-positioning member. The button element, which has a smaller caulking pressure, is caulked by a resilient force of the first spring. Then, the button element, which has a larger caulking pressure, is caulked by a resilient force of the both springs, after the first spring is compressed to be deformed with a displacement of the gap.
Abstract: A controlld deflection roll has a unique liquid barrier and heat shield which includes a chamber filled with cooling fluid. In a preferred embodiment, the barrier comprises two chambers and a space in fluid communication with both chambers for circulating cooling fluid between the chambers and into and out of the roll. The barrier is interposed between the interior cavity of the roll containing the extremely hot hydraulic fluid which actuates the apparatus for controlling the deflection of the roll, and the bearings which rotatably align the roll shell relative to the space. The barrier, thus, functions to thermally insulate the bearings from heat, whether by radiation or by direct contact with the hydraulic fluid.

The shank is encased by a sleeve and handle assembly which is used to adjust the exposed portion of the descaling members.
Abstract: Surface finishing or polishing rollers are made by successively mounting disk-shaped surface finishing elements on a spindle rotating in operation. The surface finishing elements are formed of a slitted, preferably rectangular sheet having a continuous portion of material with lamellae protruding perpendicularly therefrom. The slitted sheet is shape-fixed with binder, and the periphery of the protruding lamellae forms an ellipse. The surface finishing elements, each of which comprises an oval disk with lamellae, are mounted inclined on the shaft of the spindle so that the contour of the successively mounted surface finishing elements forms a cylinder in the axial direction of the spindle.
Abstract: Axially extending liquid-tight tapered spaces are defined in the barrel of a roll body. Tapered pistons are fitted in the spaces for engagement and disengagement with a bore inner surface defining the tapered spaces. A liquid under pressure is supplied through liquid passages to some of liquid pressure chambers at opposite ends of the tapered pistons so that the barrel of the roll body is increased or decreased in diameter. When the rolling forces are removed from the roll body, the roll body returns to its initial straight state.
Abstract: A nipple ring comprising a generally circular ring of a size adapted to fit snugly around a nipple provided with two overlapping ends which may be squeezed together to enlarge the effective circumference of the ring so that it may be placed on the nipple and then when the ends are released the ring will fit securely around the nipple. The ends may be fitted with smaller circular rings from which to hold pendant jewelry.
Abstract: A head cleaner includes a generally flat, rectangular sheath 10 formed of flexible top and bottom walls 11 and 12 as is standard in floppy disk construction. The magnetic disk that would be within the sheath is replaced by a flat, absorbent member 17 which has an opening 18 such that it can be mounted on the hub of a disk drive. One of the walls of the sheath has an aperture 22 through which head 34 can extend and contact the absorbent member. A liquid solvent is applied in the aperture to the absorbent member to dissolve built up oxides on the head. The aperture is made wider than standard apertures for floppy disks, and there are additional apertures on other edges of the sheath for providing additional windows. Other windows may be through the other wall of the sheath such that there are eight total windows in the head cleaners. Therefore, the head cleaner can be inserted into the disk drive with any edge leading and with either wall on the head side of the drive.
