Abstract: VEHICLE SUSPENSION WITH FLEXIBLE TRANSVERSAL BEAM               Abstract of the Disclosure A load-monitoring vehicle suspension including a pair of wheel assemblies carried adjacent the opposite ends of a flexible transversal beam which supports the bed in the vehicle.          This beam extends transversely of the bed's longitudinal axis, and supports the bed through two spaced journal connections which are disposed inwardly of the wheel assemblies, and which provide for the beam spaced journal axes that generally parallel the bed's longitudinal axis and intersect the beam's longitudinal axis.  Load carried on the bed causes the beam to deflect substan-tially in pure bending, and such deflection is monitored by a strain-sensitive device mounted centrally on the beam.

Abstract: ABSTRACT       A screw press for extracting liquids from materials such as fruits, vegetables, or the like having a cylindrical barrel having a concentric variable-speed helical feed and compression screw.  The rearward portion of the cylindrical barrel comprises a cage section having perforate filter screens for passing extracted liquids and filtering out undesired solids from the material being pressed formed by at least one pair of open semi-circular frames having a plurality of ribs which support replaceable filter screens.  The pair of frames is attached to a set of lower hinge blocks and is removably joined along the upper edges of the frames.  The frames may be separated at the upper edges to open in a book-like manner completely clear of the feed and compression screw, permitting cleaning of the screens and screw, or replacement of the screens.  A portion of the barrel rearward from the feed and compression screw forms a cylindrical pressing chamber having screen walls for passing extracted liquids therethrough.  The outlet end of the cylindrical pressing chamber is closed by a circular  door having inner projecting cutter bars and slidably mounted on the feed and compression screw drive shaft.          Hydraulic actuators apply adjustable pressure to the outside surface of the door.  The internal pressure of material causes the door to open for ejection of the dried material.  A clutch automatically engages when the door opens to rotate the door and the cutting bars to pare away a cake of the dried material.

Abstract: TITLE         METHOD AND APPARATUS FOR SEPARATING      SAND FROM BOTANICAL FINES                      INVENTOR     David L. SCHOLTEN     ABSTRACT     A mixture of botanical fines and sand is separated by a porous  separating  medium  horizontally  disposed  within  an enclosed chamber in which an upflowing stream of gas carries out the separation.  The porous separating medium is comprised of  a pair  of  opposed rotatively movable  juxtaposed porous members with means for rotatively adjusting the porous members so as to change the flow through area in the porous separating medium.  As a gas  flows  up through  the  porous  separating medium, only the sand passes down through the porous medium and  the  gas  entrains  the  botanical  fines  portion  of  the mixture above the porous members removing the botanical fines with  the gas  stream.   Control  of the  velocity of  gas  up through  the  porous  medium  as  well  as  the  prevention  of botanical fines from flowing with the sand down through the porous  medium  is  determined  by  the  adjustments  of  the rotatively mounted porous members.

Granted: 1984-01-17
Abstract: LED-Fiber Optic Character Printer Abstract A relatively narrow printing head scans across photosensitive material and in one scan generates a line of characters thereon.  Digital control signals selectively illuminate the LEDs formed within a matrix thereof.  A flexible loop of flat fiber optic filaments having their input ends coupled to the LEDs and having their output ends positioned within the print head, enables the use of a relatively small number of fiber optic filaments and yet provides for extremely high-speed recordation of the characters upon the film which contacts the print head.  After a line has been photo-graphically recorded, the film is stepped in a direction perpendicular to the direction of scanning of the print head and another line is recorded.  An inexpensive and highly accurate print head carriage is disclosed, along with a unique belt drive for driving the carriage without inducing torque therein, owing to possible misalignment of the drive belt.

Abstract: - ii -RADIATION CURABLE COMPOSITION FOR  RESTORATIVE AND/OR PROTECTIVE TREATMENT OF PHOTOGRAPHIC ELEMENTS ABSTRACT OF THE DISCLOSURE           Radiation curable compositions useful for restorative and/or protective treatment of photo-graphic elements are comprised of an acrylated urethane, an aliphatic ethylenically-unsaturated carboxylic acid, a multifunctional acrylate, and a siloxy-containing polycarbinol.  Photographic elements, such as still films, motion picture films, paper prints, microfiche, and the like, are provided with a protective overcoat layer which is permanently bonded to the element, and serves to protect it from abrasion and scratches, by coating the element with the radiation-curable composition and irradiating the coating to bond it to the element and cure it to form a transparent, flexible, scratch-resistant, cross-linked polymeric layer.  The protective overcoat layer can be applied to the image-bearing side of the element or to the support side of the element or to both sides.  The radiation-curable composition can also be used as a restorative composition in the treat-ment of photographic elements which have scratches, abrasion marks, and the like, which impair the appearance or projection capabilities of the element. In use as a restorative composition, the radiation-curable composition can be applied locally in the region of the defects only, to effectively eliminate them and restore the element to a substantially defect-free condition, or it can be applied over the entire surface of the element to both eliminate the defects and form a protective overcoat layer that is capable of providing protection against subsequent scratching or abrasion.
