Abstract: A  motion  transmitting  remote  control assembly  (10)  for transmitting  forces  along  a curved  path  by  a  flexible  core  element  (26) slidably disposed within a flexible conduit (12). The assembly (10) includes an elongated member (62) for adjusting the longitudinal  position of the conduit (12) by being slidably disposed within a passageway  (68)  of a  support member  (32).   A locking clip (86) is movable between a disengaged position  for  permitting  relative  longitudinal movement between the elongated member (62) and the base (32) and an engaged position for preventing longitudinal   movement   therebetween.       The improvement resides in the elongated member (62) being rotatably supported on the conduit (12) to allow rotation of the conduit (12) relative to the support member (32) while in an engaged position.

Title: Bipolar biopsy device utilizing a rotatable, single-hinged moving element
Inventor: PARINS DAVID J
IPC: A61B18/14
Filed: 1992-12-15
Abstract: BIPOLAR BIOPSY DEVICE UTILIZING A ROTATABLE, SINGLE-HINGED MOVING ELEMENT                   ABSTRACT OF THE DISCLOSURE    A bipolar biopsy device for removing tissue samples for biopsy purposes or other purposes.  The bipolar biopsy device has an elongated flexible end and a lumen extending therebetween.  A cutting head is mounted on the distal end and has a hollow fixed member containing an electrode having an electrical surface thereon and a hollow cup-shaped moveable relative to the fixed member.  The electrode surfaces are electrically connected to an outside voltage source.    A  handle is affixed to the proximal end and a core wire is affixed to the handle which extends through the lumen and is affixed to the movable hollow cup-shaped member.  The core wire manipulated by way of the handle facilitates the movement of the movable cup-shaped member.  Tissue samples are obtained by positioning the electrode surfaces close to each other about the tissue sample.  An arc is created to break tissue down by applying a voltage to the 2 electrode surfaces.  The cut tissue remains within the cup-shaped members as the device is withdrawn from the body for later biopsy purposes.

Inventor: EULER JOHN W
IPC: D06F35/00
Filed: 1992-12-23
Abstract: The present invention contemplates a rinse process which can be used with any wash cycle, but which has particular utility following a wash cycle have a highly concentrated detergent solution.      The method of rinsing fabric provided by the present invention is useful in a washer having a wash chamber rotatable about a horizontal axis. The steps undertaken in the method begin with loading fabric to be washed into the wash chamber of the washer. The fabric is then washed in a detergent solution while rotating the wash chamber about its horizontal axis for a first period of time. Next the detergent solution is drained from the wash chamber. The fabric is then rinsed by adding water to the wash chamber while spinning.the wash chamber at a speed to effect more than a one gravity centrifugal force on the fabric such that the fabric will not tumble within the wash chamber as it spins. Finally, the wash chamber is drained of the rinse water.
Patent CA-2086773-A1 (CA)
Title: Debagger/sorter machine
Inventor: MAYHAK RICHARD L
IPC: B65B69/00
Filed: 1993-01-06
Abstract: ABSTRACT    This machine removes yard waste from bags and sorts the waste from the bags.   Bags dropped into a hopper have offset slashes cut in opposite sides by blades mounted upon two rotary shafts.  The blades are widely spaced so no small bag pieces can result to permit a later sorting process.  The blades are pivoted to minimize solid tramp waste damage, and are mounted in opposing pairs for balance.   One shaft has two and the other has three blade pairs for the offset opposed cuts.   Guards, extending inward from opposed parallel hopper sides enclose each shaft and direct the bags between them.  Slots through the guards in the blade paths permit the blades to pass through.          Flexible wipers between backing plates extend inward from both sides of the slots parallel to the blade paths to bear against the blades.  The blades cuts bag material against the wipers rather than carry it through to the shafts.          The cut bags fall onto a conveyor which carries them to the  top of  an  inclined vibrating screen.  The screen is sized to pass yard waste but not bags, bag parts or tramp material.          Conveyors under the screen carry the yard waste away for disposal.   A blower over the low screen end blows the bags and bag parts off the screen.  Tramp material is vibrated off the low screen end for separate disposal.

Abstract: Abstract of the Disclosure RUBBER STOCK CONTAINING PHENOXYACETIC ACID      The present invention relates to a rubber stock containing 0.1 to 10.0 phr of phenoxyacetic acid. Addition of the phenoxyacetic acid to a rubber stock increases the low strain stiffness properties of the rubber stock and results in increased treadwear when the stock is used in tread stocks.  The phenoxyacetic acid may also be used in a rubber stock as a methylene acceptor or resorcinol replacement.  In addition, the phenoxyacetic acid functions as a silica coupling agent and provides lower viscosities for processing the rubber stock compared to rubber stocks containing conventional silane coupling agents.

Patent CA-2097217-A1 (CA)
Title: Microbial desulfurization or organic compounds
Inventor: GROSSMAN MATTHEW J
IPC: C12N1/20
Filed: 1993-05-28
Abstract: ABSTRACT OF THE DISCLOSURE          Sulfur in petroleum products, coal,  tar sands and shale  oil is undesirable, due to the  promotion of corrosion of  transportation, storage and  processing equipment  and the  emission of  sulfur  oxide gases upon  combustion  which are  a  source of  acid  rain.   Current industrial methods employed for organic sulfur removal are limited  to the extent to which  sulfur can be  removed, particularly with  regard to molecules where  the sulfur  atoms are  sterically hindered.   Most microbial methods described to date for the removal of organic  sulfur from fuels  result in  the reduction  of the  fuel value  due to  non-specific degradation of  the carbon  skeleton of  organic sulfur  com-pounds and related non-sulfur compounds  present in the fuel  mixture. This invention describes a method  for the sulfur specific removal  of organic sulfur from  fuels and  related products  utilizing novel  and newly discovered and isolated microorganisms that specifically  remove sulfur from organic sulfur compounds, especially those compounds where sulfur atoms are sterically hindered.

Title: Downhole fluid property measurement tool
Inventor: SCHULTZ ROGER L
IPC: E21B49/08
Filed: 1994-02-03
Abstract: Abstract of the Disclosure Apparatus and methods are provided for measuring a parameter of a hydrocarbon-bearing well fluid sample while the sample is still  in place  in  the  well  and  at  downhole  pressure  and temperature conditions.  A tool is lowered into the well to a downhole location.  A well fluid sample is trapped in the tool at the downhole location.   While the tool remains within the well,  the volume of the well fluid sample is expanded while repeatedly measuring the pressure of the trapped well fluid sample at different volumes and thereby generating pressure versus volume data for the trapped well fluid sample.  From this data,  various parameters  such as bubble-point  pressure  and compressibility of the sample can be readily obtained.   The apparatus is suited for drawing and testing multiple samples in succession.  After each sample is tested, it is expelled from the tool so that another sample can be taken.  The data can be stored for subsequent analysis at the surface or it can be transmitted to the surface for real time analysis.
