Title: Optical encoders
Inventor: TAYLOR ROBERT M
IPC: G01D5/347
Filed: 1990-09-20
Abstract: ABSTRACT OF THE DISCLOSURE     Conventional optical encoders have an optically-encoded plate with parallel tracks each comprising alternate opaque and transparent regions which differ in length between the tracks.  LED's direct radiation onto the upper surface of the plate and detectors located below the plate provide an output in response to radiation transmitted through the transparent regions.  In the present invention, the opaque regions are reflective and the encoder includes detectors mounted above the plate with provide normally complementary outputs in response to radiation reflected from the reflective regions.  A processor detects any loss of complementarity and determines the position of the plate close to the boundary between adjacent regions by comparing the detector outputs as one falls and the other rises.

Abstract: An  improved  sanitary  napkin  is  disclosed.   The  sanitary napkin has a laterally extensible flap which extends outwardly from one of the longitudinal edges of the sanitary napkin or a laterally extensible backsheet.   The  backsheet  or  flap may  be laterally extended from the neutral, retracted position and will return to the retracted position upon release of the disturbing force.  This arrangement provides the advantage that any adhesive strips or patches associated with the  flaps or backsheet more easily move with the undergarment of the wearer and  are less likely to be stressed or become detached from the undergarment of the wearer due to the forces encountered during typical  wearer movements.

Abstract: CARPET CUSHION WITH ADHESIVE            Abstract of the Disclosure A carpet cushion of compressible materials such as urethane foam, natural fibers or felt material has a pressure sensitive adhesive pre-coated on only one side, preferably the side which will be adhered down to a floor. A scrim webbing or other spacer element is laid into the pressure sensitive adhesive after the adhesive has been applied.  The spacer element enables the movement of the carpet cushion around on the floor for positioning prior to sticking down to the floor, and when the cushion is rolled for storage and shipment, the spacer element enables the cushion to be rolled without any release film between the rolled layers.  In the rolled form of the cushion, the spacer element or scrim webbing prevents the adhesive from strongly adhering to the adjacent opposite surface of the cushion in the roll.

Title: Flexible, kink-resistant catheter
Inventor: FEARNOT NEAL E
IPC: A61M25/00
Filed: 1990-12-20
Abstract: Fe?ot-Sisken  8-3 Abstract of the Disclosure An  extremely  small  diameter  epidural  catheter  is disclosed which is both flexible and kink-resistant when flexed.   The catheter includes a tubular sheath or tube having a passageway therein for the delivery of fluids to biological tissue.  Positioned in the passageway is a coil which is expansion-fitted therein to form a composite wall structure which is extremely flexible and kink-resistant. This composite wall structure is utilized to form a catheter having an extremely small outside diameter in a range of 0.0101" to 0.032" for delivering acceptable levels of fluid volume.  The coil comprises a plurality of closely spaced turns extending from the proximal to almost the distal end thereof.  About the distal end of the coil is a number of loosely  coupled  or  relaxed  turns  which  adds  further flexibility to the distal end of the catheter.  The tubular sheath of the catheter comprises a high tensile or flexural strength material which does not rupture or tear when the catheter is bent or flexed.  Maintaining the ratio of the outside diameter of the wire coil to the cross-sectional diameter of the individual turns within a range of 4 to 10 prevents the tubular sheath from either rupturing or kinking when the catheter is flexed or bent.

Abstract: A spray gun including a rotatable spray head for creating a spiral flow of shaping air to more effectively apply multiple coats of liquid spray onto an article without dripping. The spiral flow of shaping or fanning air is further created by a turbine mechanism or air distributor. A drive mechanism, including a reversible motor, alternately rotates the spray head in either a clockwise direction or a counter clockwise direction relative to a housing assembly of the spray gun, depending on the direction of movement of the spray gun. In this way, the spray gun can effectively apply the liquid spray to the sides of an article, such as a grill having a plurality of parallel, spaced portions. Preferably, the motor is an air motor having a drive shaft on which gearing is mounted for rotation therewith. A cylindrical portion of the housing assembly rotatably supports the spray head by bearings mounted thereon. The improved spray gun is particularly useful in paint spray systems wherein air having a flow rate in excess of 5 CFM (cubic feet per minute) and a delivery pressure of less than 15 psi over atmospheric is communicated to the spray head of the spray gun.
