  • Patent number: 5175918
    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.

  • Patent number: 5113571
    Abstract: A connector for medical devices includes a housing having an interlock member and two types of luer nuts. One type of luer nut has an interlock member complementary to the interlock member on the housing to prevent rotation of the luer nut about the housing, while another type of luer nut lacks a complementary interlock member, allowing free rotation of the luer nut relative to the housing.

  • Patent number: 5092030
    Abstract: A method for attaching a wire-identifying tab to an electric wire end, the tab comprising a marking portion having identification mark and being a cylinder having a slit extending axially over the full length of the tab, the method comprising the steps of engaging the tab with a pair of rigid sheets in contact with each other at their upper portions, from their one ends and in parallel with them, subsequently inserting the wire end into the tab while the pair of sheets are displaced apart from each other perpendicular to the tab, and finally disengaging the sheets from the tab, thus fitting an outer surface of the wire end in the tab.

  • Patent number: 5012573
    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.

  • Patent number: 5010633
    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.

  • Patent number: 5008993
    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.

  • Patent number: 5001820
    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.

  • Patent number: 4558386
    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.

  • Patent number: 4414592
    Abstract: A coupler for a magnetic head includes a flat circumferential surface around the aperture in which the head is mounted and a circumferential orifice surface outside of and adjacent to the flat surface. The orifice surface forms a hydrodynamic orifice for control of flow of air over the flat circumferential surface to couple the magnetic medium to the magnetic head by the Bernoulli effect created by movement of air between the medium and the flat circumferential surface. The coupler protrudes through a flat Bernoulli plate against which the magnetic disk is rotated.
