Title: Use of a stent with the capability to inhibit malignant growth in a vessel such as a biliary duct
Inventor: FISCHELL ROBERT E
IPC: A61M36/04
Filed: 1992-10-19
Abstract: USE OF A STENT WITH THE CAPABILITY TO INHIBIT MALIGNANT GROWTH IN A VESSEL SUCH AS A BILIARY DUCT                         ABSTRACT    A stent to inhibit malignant growth in a vessel  is provided and  includes a tubular structure whose external surface is adapted to engage the wall of a human vessel.  The stent is patent throughout its entire interior length and is formed  from  a  radioactive  material  which  is  radially expandable after insertion into the vessel of the human body.          The radioactive material is adapted to be imbedded into the vessel wall so that the radioactive material emits radiation that reduces the proliferation of malignant cells in the vessel wall that are in close proximity to the stent while simultaneously maintaining vessel patency.

Title: Fluorescent energy transfer immunoassay
Inventor: LAKOWICZ JOSEPH R
IPC: G01N21/64
Filed: 1993-01-15
Abstract: ABSTRACT OF THE INVENTION           A fluorometric luminescence immunoassay method includes forming a sample by exposing a first immune reaction reactant to a second immune  reaction  reactant  capable  of  reacting  with  the  first reactant, one of the first and second immune reaction reactants being labelled with a photoluminescent energy transfer donor and the other being labelled with a photoluminescent energy transfer acceptor complementary to the photoluminescent donor.  At least the photoluminescent donor has the property of photoluminescence, and the photoluminescent donor and acceptor are chosen so that when the first  immune  reaction  reactant  reacts  with  the  second  immune reaction reactant,  the donor and the  acceptor are  capable of interacting to produce a detectable luminescence lifetime change.          The sample is excited with radiation, and the resulting emission is detected.  The apparent luminescent lifetime is then calculated to determine the presence of a reaction product of the first and second immune reaction reactants.

Title: Enclosure for painting and a method of enforcing evaporation from a coating on a panel surface
Inventor: JEFFS CHRISTOPHER S
IPC: B05B15/12
Filed: 1993-03-10
Abstract: A coating of paint on a panel is dried by directing a narrow jet of air from a supply, preferably from an air mover,  held at a predetermined distance from the panel towards  one edge  region  of  the  panel,  the  jet  being substantially narrower,  when it reaches  the panel  edge region,  than the length of the panel edge and the jet being inclined to the plane of the panel such that the air from the jet is entrained by the panel in a spreading laminar  flow across  the panel  surface  from  that  edge region to all the other edges thereof.  This induces such laminar  flow over  substantially the whole  surface  and replaces vapor-laden air closely adjacent the surface with fresh air to accelerate drying.   In a painting booth for cars several such air movers use part of the bulk air flow in the booth.

Title: Method for treating eye disorders by reducing 12(r)-hydroxyeicosatetraenoic acid and 12(r)-dihydroxyeicosa-trienoic acid levels
Inventor: ABRAHAM NADER G
IPC: A61K33/24
Filed: 1991-09-10
Abstract: The invention relates to a method for treating or preventing ocular swelling and corneal-conjunctival inflammation. This is accomplished by administering to the eye of a subject, either before or after exposure to an ocular swelling stimulus, an amount of a heme oxygenase inducing agent sufficient to increase levels of heme oxygenase in the eye and thereby to reduce or to regulate the amount of 19 and 20 hydroxyeicosatetraenoic and 12(R)DiHETE acids present. Particularly preferred agents include stannous compounds, such as SnCl2, other metals, heme derivatives and Vitamin B12.  These compounds may be administered in various forms.
Patent CA-2093974-A1 (CA)
Inventor: FORTNER LARRY E
IPC: H01R13/58
Filed: 1993-04-14
Abstract: A modular plug (23) for terminating cordage includes a housing (41) having a free end (46) and a cordage-input end. An end portion of a length of cordage (21) to be terminated by the plug is inserted into the cordage-input end of the housing to cause exposed individually insulated conductors extending beyond a jacketed portion of the cordage to be received in a conductor-holding portion of the housing. Blade-like terminals (42-42) inserted into slots opening to an exterior surface of the housing engage electrically the conductors. An anchoring member (61) is caused to be moved to an operative position whereat a primary jacket anchoring surface (74) of the anchoring member becomes disposed in compressive engagement with a jacket of the cordage. The geometry of the anchoring member is such that the primary anchoring surface in an unoperated position is angled to a longitudinal axis of the end portion of the length of cordage. Also, the jacket anchoring surface has suitable length so that when in an operated position in which the jacket anchoring surface is substantially parallel to the longitudinal axis of the end portion of the length of cordage, relative motion between the housing and portions of the cordage outside the housing do not induce undue stress concentrations in the cordage. The anchoring member secures the end portion of the cordage against unintended movement with respect to the housing and transfers forces applied to the cordage to the housing. Strain-relief facilities also are provided for the insulated conductors and are such that a conductor restraining bar (75) under the application of forces is moved substantially linearly into engagement with the conductors.

Title: Protein production from immortal cells grown in vivo
Inventor: WHITE DAVID J G
IPC: C12N5/16
Filed: 1992-03-16
Abstract: Antibodies or other protein derived from a given species can be produced in a discordantly related host animal of choice by culturing a hybridoma or other immortal protein-producing cell line in the peritoneal cavity of the host animal, if both the humoral immune response and the cell-mediated immune response of the host animal are compromised. The humoral immune response can be compromised congenitally; so for example C3-deficient animals can be used. The cell-mediated immune response is preferably compromised by administering cyclosporin A. This enables human-derived antibodies to be produced in vivo and in general it allows the scaling up of in vivo production methods by using larger animals than mice, which are generally currently used.

Title: Safety system for passage closure members
Inventor: SOMMER FRANK-UWE
IPC: E05F15/47
Filed: 1992-05-23
Abstract: ABSTRACT           A  safety  system  for  a  passage closure member,  such as a gate, door, window,  sliding roof or the like,  has a drive whose maximal admissible strain value is adjustable and a control device by means of which the drive can be switched off.  When the  drive  is  switched  off  because  the  maximal admissible strain value has been attained, a signal S2 at the moment in time T2 is transmitted to the control device.  In the area of the pressing and/or closing edge of the closure member  is  arranged a sensor that transmits a signal S1 at the moment in time T1 when an obstacle occurs.  The control device calculates, when the maximal admissible strain value is  attained,  the differential     value     between the   moments  in  time .DELTA. Treal = T2-T1.   The control device   compares   the   value   .DELTA. Treal   with      a predetermined  value Tprede.,  and when .DELTA. Treal is higher than  .DELTA. Tpredet.,  the  direction  of  movement  of  the closure  member is changed.

Title: Electrical switch control device
Inventor: HUEN RAICO H W
IPC: H01H3/26
Filed: 1993-12-01
Abstract: ABSTRACT A battery-operated automatic electrical switch control device to be mounted on an existing wall switch. A back frame is mounted behind the existing switch plate and a casing containing the electric circuitry and moving components of the device clips around the switch plate and onto the frame. Inside the casing is a printed circuit board wired to a DC motor that drives a cam. The printed circuit board is connected to a sensor or timing component, also in the casing, which signals the turning on or off of the switch. Such a signal, which may originate from a remote control unit or from changes in the local environment, is passed on to the motor, which drives the cam to rotate. The cam follower has on its tip a claw which grasps the actuating knob of the wall switch. The linear movement of the cam follower in response to the turning cam causes the knob to be pushed up or down, turning the switch on or off accordingly. Alternatively, a manual override button on the casing can be used to cause the motor to drive the cam follower and turn the switch on or off.
