Abstract: An improved dipstick assembly is provided for measuring liquid level in a chamber containing liquid and gas in which the liquid may be agitated, and in which the gas may have a pressure different from atmospheric.  An example is the oil reservoir or crankcase of a reciprocating apparatus while the apparatus is running.  A tube is provided for attachment to an upper portion of the chamber, the tube extending downward into the liquid.  A liquid level indicating device is inserted in the tube.  A valve is provided at or near the bottom of the tube to close it off when the liquid level measuring device is removed, but which is opened when the device is inserted, so that a reading can be made.  The valve prevents loss of liquid through the tube when the measuring device is removed, and prevents gas in the chamber from communicating with the atmosphere.  When the measuring device is inserted, a seal at or near its upper end prevents  such loss or communication.   Various  economical  and reliable designs are provided for the valve.

Abstract: A header heat plate for a large paper roll wrapping machine comprising a plurality of separate face plate sections that are mounted on a common backing plate to form a complete header plate for applying a roll header to an end of a paper roll. A roll header is temporarily held to the face plate sections through the application of a vacuum suction to openings in the face plate sections. Each face plate section includes heating elements integrally molded therein. These are heated to activate a heat sensitive adhesive contained on the roll side of the roll header. A wrapping paper is applied to the roll and crimped over interior roll headers inserted at the ends of the rolls. Grooves are cut along the side edges of the wrapping paper to reduce the amount of wrapping paper overlap and indentations in the ends of the paper rolls caused thereby.

Granted: 1999-08-24
Abstract: A cartridge assembly (90) for holding a lyophilized product, forming a disposable portion of a pen injector (104), includes a cylindrical glass cartridge (58) adapted to receive the product, a closure cap (20), a cartridge case (76), and a plunger mechanism.  The closure cap (20) is adapted to retain an elastomeric disc seal (52) during lyophilization and includes diametrically opposed ledges (38, 40). The closure cap (20) and seal (52) are adapted to cover a neck portion of the ampule (58), the neck portion having on its end a radially extending circumferential flange (62). The ledges (38, 40) of the closure cap (20) and the flange (62) of the neck portion allow the closure cap (20) to remain open during lyophilization, oxygen purge and nitrogen overlay. An oval-shaped indentation formed on the inside of the closure cap (20) aids in snapping the closure cap (20) about the flange (62) without crimping to retain the closure cap (20) underneath the flange (62). Reconstitution of the lyophilized drug is accomplished without foaming by use of an obliquely angled connector (30) which causes the diluent to indirectly impinge on the drug. The injection pen (104) and cartridge assembly (90) cooperate such that the length of travel of the plunger rod (108) during retraction is less than the axial length of a recess (107) in the rod tip (73).

Abstract: A device for aligning and measuring a hollow, rotatable bore includes a laser beam source within a housing having an aperture in its front face for passing the beam. The housing is mounted at one end of the extruder bore to project the beam through the bore to be detected by a target at the opposite end.     The diameters of the aperture and bore are concentric and the laser beam defines an axis that is alignable with the axis of rotation of the rotatable member, using target signals, by vertical and horizontal displacement with micrometers disposed on the rear face of the laser housing. Various arrangements for mounting the housing on the extruder are disclosed. The target includes a sensing cell in a housing mounted in an adapter with four balls disposed on its periphery 90° apart. The housing orients the cell plane coincident with the plane of the four balls and the diameter at the four balls is dimensioned to exceed that of the bore to be measured so that the target member when tilted and inserted into the bore will jam into place at an angle. The four balls can be urged into contact with the inside diameter of the bore, resulting in a target that is self-centered. In another mode, the housing may be moved so that the cell plane is perpendicular to the axis of the bore to permit the diameter of the bore to be checked.

Title: Surgical dissector
Inventor: SIEROCUK THOMAS J
IPC: A61B17/02
Filed: 1996-03-21
Granted: 2009-02-03
Abstract: A surgical instrument having an elongated shaft to which is attached an inflatable balloon, commonly referred to a "balloon dissector", for dissecting a desired layer of internal bodily tissue from remaining tissue layers to create an operative space is disclosed. Alternatively, an instrument without a balloon can be used to perform a manual dissection. In one embodiment, the instrument has a tissue-contacting element in communication with the shaft distal end, and at least a portion of the tissue-contacting element is transparent. The instrument is adapted to receive an endoscope through its shaft and extend to adjacent the tissue-contacting element. The endoscope is supported and positioned in an extension assembly. The instrument provides for visualization using the endoscope as the instrument is advanced through tissue, but prevents direct contact between the tip of the endoscope containing the lens and the tissue. The extension assembly also enables the endoscope to be adequately positioned and supported beyond the shaft distal end. When the instrument incorporates the balloon, the endoscope can extend into the lumen of the inflated balloon. In this way, improved visualization during use can be obtained.

Title: Low-crosstalk modular electrical connector assembly
Inventor: RAINAL ATTILIO JOSEPH
IPC: H01R13/719
Filed: 1996-06-10
Granted: 2001-01-16
Abstract: A modular electrical connector assembly to which an electrical telecommunication cable is connectable for communicating electrical signals between the connector assembly and cable. The connector assembly includes an electrically nonconductive body and a crosstalk energy emitting electrical interference source on the body and/or on or proximate the connector assembly. Electrically conductive first and second leads on the body define an electrical signal circuit for carrying electrical signals communicatable with the cable. The first lead is located more closely proximate to the interference source than is the second lead such that a greater amount of crosstalk energy from the interference source is electromagnetically impressed on the first lead than on the second lead to thereby define a difference in crosstalk energy on the first and second leads. A parasitic sized RF chip capacitor connects the interference source to the second lead for transferring crosstalk energy therethrough in an amount sufficient to substantially equalize crosstalk energy on the first and second leads and thereby reduce crosstalk-induced interference in the electrical signal circuit.  In this manner and existing Category 3 connector assembly (10 Mbs) is transformed into a Category 5 connector assembly (100 Mbs) for use with signal transmission by optical fiber to buildings and the like.
