Granted: 1992-04-07
Abstract: ABSTRACT OF THE DISCLOSURE    A surgical table is provided which is capable of conventional surgical table functions and is provided with a radiolucent tabletop which may be horizontally displaced to allow radiographic procedures to be performed without requiring relocation of the patient.  The surgical table includes a base member which may be locked to a floor mount pivot.  The base member supports a table superstructure which may be raised and lowered and tilted relative to the longitudinal axis of the tabl as well as tilted relative to a lateral axis of the table.  A carriage assembly is provided intermediate the tabletop and the superstructure which allows the translation of the tabletop both longitudinally and laterally.  Locking means are provided to prevent the horizontal translation of the tabletop when the table is in the surgical mode.  Control means are provided to select either the surgical mode in which the tabletop is locked to the superstructure or the translation mode in which the tabletop may be translated relative to the superstructure.  In the translation mode the table is locked to the floor bracket and the tabletop may be displaced relative to the superstructure.  In addition, means are provided for automatically returning the table to a level condition either in the surgical mode or in the translation mode.

Granted: 1994-12-20
Abstract: The invention relates to a method of detecting a possible leak in a vacuum package, which comprises - placing the package in a gauging space, - shutting off the gauging space, - applying a pressure in the closed gauging space higher than that in the vacuum package, and - gauging the pressure in the gauging space as function of the time for a predetermined gauging period.        At least two identical vacuum packages are each placed in a separate gauging space of identical size. A mutually identical initial pressure is applied in the closed gauging spaces and the pressure variation is simultaneously gauged in the closed gauging spaces, while the difference in pressure variation between the two gauging spaces is determined.        The invention further relates to an apparatus for detecting a possible leak in a vacuum package according to the above method, said apparatus comprising at least two gauging spaces of identical size, each for receiving an identical vacuum package. These gauging spaces are connectable to a common space. The apparatus also comprises means for shutting off each gauging space from the common space, as well as means for simultaneously gauging the pressure as a function of the time in each gauging space, and means for determining the difference in pressure variation between the two or each pair of gauging spaces. The gauging spaces can be bounded by stationary walls or by a sheet-like, flexible and gastight body.

Title: Copper-glad steel trolley wire and a method for manufacturing the same
Inventor: TAKAYAMA TERUYUKI
IPC: H01B1/02
Filed: 1988-09-28
Granted: 1992-12-29
Abstract: ABSTRACT    In a copper-clad steel trolley wire, the peripheral surface of a core, formed of a steel wire, is covered by a copper or copper-alloy covering layer.          Forty-five to 75 % of the cross-sectional area of the copper-clad steel trolley wire is occupied by the covering layer.  The core and the covering layer are metallurgically bonded to each other.    Even if the covering layer is worn away so that the core is exposed, corrosion cannot advance at the boundary between the core and the covering layer, since the core and the covering layer are firmly metallurgically bonded to each other.    The composite cast rod, obtained by the dip forming method, is hot-rolled under predetermined conditions so that the copper or copper-alloy covering layer is metallurgically bonded to the steel core.          Thus, the copper-clad steel trolley wire with a uniform covering layer thickness can be manufactured at low cost.

Abstract: ABSTRACT OF THE DISCLOSURE           A culture and transport assembly for enclosing a percutaneous access device within a sealed outer container to maintain the device under sterile conditions during transport while accommodating culturing of a coating of dermal cells on a portion of the device while the device is retained within the container.  The container includes liquid tight sealed removable, disposable chamber encloses said surface, said chamber being provided with openings for introduction therein of finely divided living dermal tissue suspended in a liquid carrier, thus providing a means for formation of the cultured surfaces which can be easily handled.  The disposable chamber is removed and discarded at the time of surgery.  In one embodiment, the container has a removable cap to which a culture well body is attached.  The percutaneous access device is releasably clamped between the bottom of the body and an underlying platform with a portion of the device projecting into a bore in the body.  When the device is so clamped, the bore constitutes a sealed culture chamber in which the dermal cell culturing procedure may be performed by introducing cells and culturing solutions into the chamber via fluid passages extending from the chamber to connectors accessible at the exterior of the cap.

Abstract: A B S T R A C T An improved gas discharge lamp having (i) a cylindrical quartz envelope with (ii) a flat circular disk magnesium fluoride window substantially transparent to short wavelength light at one end of the cylindrical envelope, (iii) two tungsten or molybdenum electrodes each of which is sheathed in a capillary tube, and (iv) a partition within the envelope and between the tube-sheathed electrodes which partition defines, in combination with the envelopes, a bore about each of the electrodes and its sheathing tube.  A gas discharge path between the electrodes produces bright light spots at the capillary tube orifices, at a region of the lamp proximate the window.  The windowed quartz envelope is inexpensive to manufacture.  The partition imparts strength and maintains the capillary tubes in precise alignment during manufacture.  The tungsten or molybdenum electrodes support high currents providing high illumination.  The flat magnesium fluoride window passes undistorted short wavelength light particularly suitable for use in instrumentation.
