Title: Apparatus for detecting flow amount of fluid in passage
Inventor: YAMAZAKI SHIGERU
IPC: G01F1/05
Filed: 1987-11-04
Granted: 1992-12-22
Abstract: "Apparatus for Detecting Flow Amount of Fluid in Passage"     ABSTRACT     An apparatus for detecting the flow amount of a fluid passing through a passage.  The apparatus comprises a scroll chamber having a circular horizontal cross section and having an inlet opening defined in a tangential direction of the scroll chamber and an outlet opening defined at a substantial center portion of a bottom surface of the scroll chamber.  The fluid is introduced through the inlet opening and discharged from the outlet opening.  In the scroll chamber, a conically protruding member is provided on a substantial center portion of the top surface of the scroll chamber so as to be protruded vertically and downwardly along the axis of the scroll chamber.  A spheral member encased in the scroll chamber is turned about the protruding member and along a wall of the scroll chamber in response to introduction of the fluid through the inlet opening.  The flow amount of fluid is measured by detecting the number of turning of the spheral member.  The scroll chamber has a conical portion whose diameter decreases toward the upper side and is arranged so that the spheral member is turned with it being brought into contact with the taper surface of the conical portion.  This provides an extremely stable detection of the fluid flow.

Title: Urine specimen collectors and method of detecting spurious urine specimens
Inventor: PARRISH JAMES M
IPC: A61B10/00
Filed: 1988-04-25
Granted: 1991-11-12
Abstract: ABSTRACT OF THE DISCLOSURE            Urine specimen containers combined with a temperature sensitive member which is capable of signalling a spurious urine specimen when placed in a sufficiently close heat exchange relationship with a urine specimen.  The temperature sensitive member contains portions which change color irre-versibly at preselected temperatures when placed in sufficiently close heat exchange relationship with a urine specimen.  The temperatures at which the irreversible color changes are made are selected slightly below normal body temperature and slightly in excess of normal body temperature such as from about 90°F. to about 100°F.  The urine specimen collector itself includes a bowl-shaped member with an integral handle.  The bowl-shaped member is contoured to fit in close proximity to the body of the user.  A cover member is pivotally attached to the handle and functions as a splash guard for the user.  The cover member also has a raised boss terminating in an open top to permit urination through the cover member.  The opening of the raised boss in the cover member is substantially in line with a threaded connection for a collection container which is screwed onto the bottom of the bowl-shaped member.  The cover member has a portion thereof spaced from a frontal portion of the bowl-shaped member to provide an overflow from the bowl-shaped member.

Inventor: ROHRER PAUL
IPC: B32B33/00
Filed: 1988-06-16
Granted: 1991-09-24
Abstract: ABSTRACT OF THE DISCLOSURE            The multi-layer body member consists of a support member, e.g. a glass fiber tissue impregnated with a thermosettting resin which is covered by a layer of thermosetting adhesive resin. In order to protect the sticky surface of the adhesive resin, a protection foil made of a material shrinking under the in-fluence of heat is provided. The foil comprises slits which open to apertures after a preliminary heat treatment such that an essential portion of the sticky resin surface is freely ex-posed. Thus, the need to remove the protection foil prior to applying the multi-layer body member to the surface to be rein-forced is removed.

Title: Apparatus for delivering a liquid
Inventor: GILL DAVID C
IPC: B05B12/02
Filed: 1988-12-30
Granted: 1993-04-20
Abstract: ABSTRACT      A liquid such as a herbicide is delivered from spray nozzles (4) on a boom (2).  The herbicide is supplied from a herbicide container (8) by a pump (18), and is diluted with water supplied from a tank (10) by a pump (12).  The speed of the herbicide pump (18) is controlled by control means (22) and is responsive to the travel speed of the apparatus.  The volumetric output of the pump (18) is calibrated by supplying the herbicide to a calibration vessel (32) during a test cycle in which the apparatus travels over a predetermined distance.  Correction factors can then be-input to the control means (22) in order to bring the volumetric output of the pump (18) into line with desired flow rates.

Abstract: Abstract of the Disclosure An adjustment apparatus for supporting a slidable door is disclosed that has a bar-like pivotable frame member.  A pair of track followers, such as rollers, are mounted adjacent the ends of the frame member.  A door has upper and lower edges, and opposite side edges.  The upper door edge is piv-otally connected to a central portion of the pivot frame mem-ber.  A pair of stems are pivotally fastened to the frame mem-ber adjacent the ends of the frame member.  Each stem is also mounted in a sliding relationship with respect to the side edges of the door.  In this way, the frame member can pivot with respect to the upper door edge.  When installing the slid-able door, this pivot action allows the door to be flush against the frame structure, even though the wall or frame may be out-of-plumb.  Final adjustment of the apparatus simply re-quires tightly fastening a central bolt and at least one screw.
