Abstract: ABSTRACT OF THE DISCLOSURE      A photographic display for depicting a three dimensional visual image including a supporting frame for displaying a photographic image including a height, width and a predetermined thickness.  A viewing screen is provided and disposed to extend substantially along the height and width of said supporting frame and being positioned on a first side thereof.  The viewing screen includes a plurality of substantially parallel lines having a predetermined width and being separated by clear spaces.  A photographic image is provided and disposed to extend substantially along the height and width of said supporting frame and being positioned on a second side thereof, spaced from said first side by said predetermined thickness of the supporting frame.  The photographic image includes a plurality of substantially parallel image segments having a pre-determined width corresponding to the width of the lines positioned on the viewing screen and the lines positioned on the photographic image are in alignment and registration with the lines positioned on the viewing screen.

Abstract: ABSTRACT     VENOUS RESERVOIR BAG WITH INTEGRAL HIGH-EFFICIENCY BUBBLE                    REMOVAL SYSTEM           A  liquid-gas  bubble  separator  comprising  a container having an inlet for a fluid which includes liquid and gas bubbles, an outlet and upstream and downstream vents. A filter element is provided in the container between the inlet and the outlet.  The filter element permits the passage of the liquid and inhibits the passage of the gas bubbles. The filter element is between the upstream and downstream vents so that gas bubbles which do not pass through the filter element can be vented through the upstream vent, and any gas bubbles downstream of the filter element can be vented through the downstream vent.  A bypass passage is provided around the filter element.  A portion of the filtered fluid is recirculated through the bypass passage to prevent forward flow through the bypass passage when the filter element is clean, and such recirculating flow is terminated when the filter is clogged to a predetermined degree to thereby open the bypass passage for forward flow.

Title: Product-dispensing method and apparatus
Inventor: FELT GEORGE R
IPC: G01F19/00
Filed: 1987-03-18
Granted: 1992-08-11
Abstract: ABSTRACT OF THE DISCLOSURE           An aerosol spray dispenser of flowable pharmaceutical product is provided with a flotation stabilizing arrangement such that it will float in water in a stabilized erect position even when empty of product; a scale is associated with the dispenser so that the depth at which it floats can be read by comparing the position of the surface of the water in which it floats with graduations on the scale.  The stabilizing action may be obtained by placing the dispenser in a floatable bottom-weighted vial, with the scale located in the exterior of the vial, and the combination of vial and dispenser then floated in water.  In other embodiments the vial need not be used, in which case the dispenser itself may be bottom-weighted to assure its stabilized erect flotation and the scale placed on the exterior of the dispenser, for, a cap may be provided for the dispenser which is positioned on the dispenser while both are floated in the water, the cap being top-weighted so that the assembly floats stably upside-down.  In the latter case the graduations may be placed on the dispenser, or on a strip integral with the cap extending along the outside of the dispenser; alternatively, the cap may be provided with an integral skirt which extends completely around the dispenser and to its bottom end, with the scale located on the exterior of the skirt.

Title: Returned stair tread having moisture compensated joint
Inventor: YOUNG ROBERT H
IPC: E04F11/16
Filed: 1988-01-13
Granted: 1992-04-28
Abstract: ABSTRACT OF THE DISCLOSURE         A returned tread for use on an open portion of a stairway having a stair tread constructed of wood and a return nosing joined on at least one side edge of the stair tread so as to form an exposed shaped or mitered joint on a forward side edge portion of the assembly.  The surface of the nosing which opposes the stair tread and the side edge of the stair tread are joined along at least a part of their adjoining surfaces by tongue and groove construction.  A single finishing nail, wood screw or ocher suitable fastener secures the nosing to the stair tread at a position just rearward of the exposed joint.  As a result, the stair tread and nosing will not slide relative to one another at the position of the fastener or in a region next to the fastener that includes the exposed joint as the rest of the stair tread expands and contracts in width over a range due to ambient temperature and humidity changes.   In the alternative, a suitable wood adhesive may be applied to the opposing surfaces of the nosing and stair tread in and along the exposed joint without using the fastener.  Preferably, the nosing and stair tread are secured to one another by both gluing the opposing surfaces of the nosing and tread together along the exposed joint and by fastening the nosing and tread together with a suitable fastener as previously explained.

Granted: 1994-07-26
Abstract: ABSTRACT OF THE DISCLOSURE          FILM COATING FOR RIGID, SMOOTH SURFACES        Covering a rigid but pliable, smooth surface with a one-sided matte embossed polyethylene film, where the non-embossed smooth side of the film is in direct contact with the smooth surface being covered.  Adhesion of the smooth side of the film to the smooth surface to which it is applied is effected much like a vacuum adhesion as seen when a drop of water is placed between two sheets of glass.  The embossed side of the film forms microscopic air pockets when rolled upon itself which prevents block-ing.  This feature allows the non-embossed side to be made as smooth as possible without the need for an anti-blocking agent.

Abstract: ABSTRACT OF THE INVENTION         What is described is a hair treatment device with a winding mandrel driven by a reversible motor and with a hair dryer the outflow nozzle of which is installed perpendicularly to the axis of the winding mandrel and which is adjustable in such manner that the emerging flow reaches the hair wound up on the winding mandrel at a tangent. The direction of flow of the winding mandrel and the position of the outflow nozzle of the hair dryer are coupled in such manner with the activation of the reversing switch of the drive motor that the hair wound up on the winding mandrel is subjected to air flow in the direction of the hair ends. Reversal is effected via two switches (1, 2) of which the first switch (1) is actuated directly by the reversing switch (3) and the second switch (2) is actuated only after a certain time delay.
