Abstract: DRAINAGE CATHETER                         Abstract A medical device (10) of improved design includes an elongated member (12) for insertion into the body, a flexible tension member (20) extending along the elongated member to an attachment upon which tension is desired to be applied, and locking means (30) associated with the elongated member at a point outside of the body to secure said flexible member under tension.  The locking means consists of a pair of locking members (38, 40) disposed in close association with each other at a predetermined point along the proximal portion of said flexible tension member, one locking member (38) being movable relative to the other locking member (40) in motion laterally across the path of the tension member under tension to a locking position in which the tension member is bent and secured between cooperating locking members.  Preferably, one locking member is rotatable relative to the other.  The flexible tension member may extend within a fluid-carrying conduit (41) defined by the elongated member, which in preferred embodiments is in the form of a catheter.

Title: Window having a pivotal step
Inventor: GUELCK VOLKER
IPC: E06B3/34
Filed: 1987-04-22
Granted: 1991-04-09
Abstract: ABSTRACT         A window has an inner sash and outer sash that are removable from a frame.  A pivotal step is located along an outer surface of the inner sash.  For a double-hung window, there are two pivotal steps, one along each side of the outer surface of the inner sash.  For a horizontal slider window, there is one pivotal step along a top of the outer surface of the inner sash.  When the inner sash is tilted inward or removed from the frame, the pivotal step can be rotated inward to allow the outer sash to be tilted inward or removed.  When the pivotal step is in an operating position in the window, it greatly reduces the air flow from an exterior of the window to an interior of the window around the sashes.  With previous windows, there is no step immediately adjacent to an outer surface of the inner sash or, if there is such a step, the presence of the step makes the removal of the sashes cumbersome.

Abstract: BLOOD PUMPING SYSTEM AND METHOD         ABSTRACT A heart-assist system and a method for operating same are described in which a pump is connected to a ventricle to receive output therefrom. An actuator operates to cause the pump to conduct a fill cycle in which it receives output from the ventricle to which it is connected, and to conduct an eject cycle in which the contents of the pump are expelled.  The time of initiation of at least one of the fill cycle and the eject cycle is varied in relation to systole of the ventricle to which the pump is connected to thereby vary the loading of the ventricle.  Several techniques for detecting termination of systole are described including a compliant stop on the pump.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to carrying out thermal cracking of hydrocarbons, or other thermal conversions of organic substances in a reactor, for which a suitable reaction time is extremely short, e.g. of the order of milliseconds. Particulate solids are used as heat carrier and as feed an organic substance is used in the form of a gas which may contain some liquid; the hot particulate solids are introduced at low or no velocity into contact with the gas, which is at substantially higher velocity; the solids accelerate in passing through the reactor but the reaction is terminated sub-stantially before the solids attain the velocity of the product gas.  Contact times are short so that the solids do not accelerate to erosive speeds. The velocity dif-ferential enhances the heat transfer rate which makes short reaction times feasible.

Abstract: Chlorothio-sulfonamide modified rubbery terpolymers, such as chlorothio-sulfonamide modified EPDM rubbers, have utility in a variety of applications.  For example, such modified rubbers can be utilized in the sidewalls of pneumatic tires.  Such modified rubbers are prepared by reacting a terpolymer of ethylene, an .alpha.-olefin containing from 3 to 6 carbon atoms, and a non-conjugated diene containing from 6 to 12 carbon atoms with a N-chlorothio-sulfonamide.  The present invention is based upon the unexpected finding that the rate of this reaction can be greatly accelerated by conducting it in the presence of a saturated aliphatic carboxylic acid containing from 6 to 30 carbon atoms, such as stearic acid.  The present invention accordingly discloses in a method of preparing a N-chlorothio-sulfonamide modified terpolymer by reacting a terpolymer of ethylene, an .alpha.-olefin containing from 3 to 6 carbon atoms, and a non-conjugated diene containing from 6 to 12 carbon atoms with a N-chlorothio-sulfonamide; the improvement which comprises conducting the reaction in the presence of at least one saturated aliphatic carboxylic acid containing from 6 to 30 carbon atoms.

Title: Apparatus and method for measuring dark and bright reflectances of sheet material
Inventor: BURK GARY N
IPC: G01N21/86
Filed: 1989-04-19
Granted: 1993-03-30
Abstract: Abstract of the Disclosure Apparatus (10) and methods for measuring dark and bright reflectances of translucent sheet material (2) are disclosed.  A first optical means illuminates one side of the sheet (2) with a source of electromagnetic radiation.  A portion of the radiation is transmitted through the sheet (2) and another portion is reflected by the sheet.  Optical gating means (30) are positioned adjacent the other side of the sheet (2) in a fixed position relative to the first optical means.  The optical gating means (30) absorbs substantially all of the transmitted portion of the radiation when switched to a dark state and reflects substantially all of the transmitted portion of the radiation back through the sheet (2) when switched to a bright state.  A second optical means collects the reflected portion of the radiation and the portion of the transmitted portion of the radiation reflected by the optical gating means (30) and retransmitted through the sheet (2) to provide a total reflectance.  The total reflectance has a dark reflectance intensity when the optical gating means (30) is in the dark state and a bright reflectance intensity when the optical gating means is in the bright state.  Sensing means (60) is responsive to radiation collected by the second optical means for providing a dark signal corresponding to the dark reflectance intensity and a bright signal corresponding to the bright reflectance intensity.  The dark and bright signals can be used to compute values for attributes of the sheet (2) including opacity and color.

Abstract: ABSTRACT OF THE DISCLOSURE:        Disclosed is a refuse compactor particularly designed for aircrafts, which comprises a compaction chamber having a movable wall panel that extends parallel to one of the side wall of the compaction chamber, and can be moved away from this side wall through a very simple mechanism which is operated either directly by a hand-lever or indirectly through the service door of the compactor cabinet when this service door is closed for refuse compaction into a container.   In both cases,  the very purpose of this lateral motion of the movable wall panel relative to the adjacent side wall is to release the pressure of the refuse container inside the compaction chamber after completion of the compaction,  and thus makes this container easily discardable into a storage chamber if any, or out of the compactor.  The operation of the movable wall panel is exclusively mechanical and is therefore very simple and reliable.
