Abstract: Povidone is sterilized by irradiation in the presence of iodine and iodide ions. In particular solutions of povidone are sterilized by gamma-irradiating the povidone in the presence of iodine and iodide ions, which are present in an amount which prevents gelation at that dose of gamma radiation which would cause gelation in the absence of the iodine and iodide ions. The gamma irradiation of povidone may be effected in the presence of iodine with both iodide and iodate ions or as povidone-iodine in the presence of iodide and/or iodate ions. Sterilization thus effected by gamma radiation while preventing gelation of the povidone and degradation of the povidone-iodine.

Abstract: Circuit arrangement for the electric supply of devices in a telephone set enabling to supply the devices with an optimum power. To this effect, there is provided at the input of the telephone set a transverse member (35) with an ohmic resistance characteristics which regulates for all loop currents the admissible maximum input voltage so that it is always possible to draw the maximum power. A priority network (36) connected downstream of the transverse member distributes said power to the different consumers, the currents which are not necessary for a consumer being distributed to the consumer having the next lowest priority. A lower priority output with inherent current limitation supplies a sound hearing or free speaking final stage (38, 39), so that said final stage has always at disposal the maximum excess power.

Abstract: A downhole chemical cutting tool having an anchoring system employing interchangeable slip arrays of progressively larger outside diameters that can be used economically to adjust the range of the anchoring system.  The range can be further adjusted by utilizing interchangeable slip expansion mandrels.  This anchoring system both anchors and centralized the chemical cutting tool.  The cutting tool includes a slip shaft that provides fluid communication between the propellant section and chemical section, thence to the slip piston that receives the interchangeable slip arrays.  The slip shaft and slip piston are threadedly connected to a set coiled tension spring.  Interchangeable slip expansion mandrels connected to the slip shaft below the slip arrays are constructed with ball bearings on the surface that receives the slip arrays expanding the slip segments into a gripping engagement an usually large angle as the slip piston is actuated by the application of fluid pressure during the cutting operation. The interchangeable slips are configured so that the gripping teeth will simultaneously engage the internal surface of the wellbore pipe being cut. During the cutting operation the application of fluid pressure activates the slip assembly and discharges the chemical cutting fluid from the chemical section into the fluid jet section of the tool at high temperature and velocity.  After the release of fluid pressure the slip assembly reliably releases the tool due to the large    ' angle of engagement of the slip segments.

Granted: 1994-07-05
Abstract: ASSAY ELEMENT                   ABSTRACT OF THE DISCLOSURE              There is described an assay element suitable for use in an automated analytical test instrument for assaying a fluid sample. The element includes a thin porous member possessing a high degree of capillarity such as a fibrous mesh pad supported within a guide defined by surfaces contiguous the porous member. The dimensions of the porous member and its degree of capillarity are such as to provide for capillary transport of fluid through the member. A fluid dispenser and a fluid collecting chamber are disposed contiguous to opposed ends of the porous member. The fluid dispenser is formed as a well with a port at the bottom of the well, the port being contiguous the porous member and having a ridge extending along a perimeter of the port. The ridge protrudes into the porous member a distance sufficient for entraining fluid present in the well to propagate within the member rather than along an interface between a surface of the member and guide surfaces which hold it in place. Reservoirs may also be provided in the housing for storing reagents, mixing fluids and diluting samples so as to provide a self contained assay element. Optionally, and preferably, there may be an opening in the housing to provide fluid access directly to the central area of the porous member.

Abstract: An optical fiber splicing device (20) includes a glass cylindrically shaped capillary tube member (24) having a passageway formed therethrough eccentrically of the longitudinal axis of the capillary tube member. The capillary tube member is provided with a slot (86) such that a portion of the passageway in the form of a groove (88) extends across a planar surface (87) formed by the slot. The capillary tube member is mounted in a housing (22) which is made of a material and formed to provide a lens opposite to the slot to facilitate visual inspection of ends of end portions of two optical fibers which are positioned in the groove. A spring clamp (26) is mounted to the housing in a first position spaced from the planar surface to allow insertion of fiber end portions into the groove. The clamp is moveable to a second position where it is secured to the housing in a position which causes a portion of the clamp to engage the fiber end portions along at least a portion of the planar surface to hold the fiber end portions in secured alignment with each other.

Filed: 1991-01-21
Granted: 1997-05-06
Abstract: A loading arrangement for loading fluids onto a ship at sea comprises a coupling manifold on board said ship. A pulling line which is connected with a winch on board said  ship  and  comprises  a  loading  fork  with  two diverging parts which at a respective end are connected with coupling head, may be guided on board and towards said winch,  via a guide pulley which is mounted on board said ship to be movable in a controlled manner in the direction of pulling line towards and away from said winch. Coupling manifold is mounted to be slewable about  a horizontal  axis,  so  that  it may be  slewed towards  and  away  from  the  loading  fork.  Coupling manifold has a guiding means in the shape of a curved screen,  which in vertical  elevation has a trapezoid shape adapted to  the triangular area of loading fork between the two parts. When loading fork is brought into a position outside coupling manifold by the aid of winch,  the  coupling  manifold  may  be  slewed  in  a direction towards the loading fork so that the guiding means,  i.e.  curved screen,  contacts loading fork and fixes  the  latter  in  the  fork  plane.  Cooperation between screen and fork is facilitated by the fact that guide  pulley  is,  as  mentioned,  displaceable  in  the direction of the pulling line, towards and away from the winch.
