Title: Magnetic operator flow device
Inventor: VELIE WALLACE W
IPC: F16K31/08
Filed: 1989-09-28
Granted: 1993-09-07
Abstract: ABSTRACT OF THE DISCLOSURE          A magnetically operated flow device contains a flow responsive magnetically attractable body within a flow passage defining upstream and downstream directions therein.   The body is movable in upstream and downstream directions in the passage.          The passage includes upstream and downstream limit positions to define upstream and downstream limits of movement of the body within the passage.  Magnetic means are provided to attract the body against the fluid flow within the passage to the upstream limit position.  The body constitutes a drag obstruction to fluid flow through the passage and will, therefore, decouple from its upstream magnetically retained position in the passage and move to the downstream limit position when drag forces (i.e. flow) increase to the design limit value.

Granted: 2000-02-01
Abstract: An improved stereolithography system for generating a three-dimensional object by creating a cross-sectional pattern of the object to be formed at a selected surface of a fluid medium capable of altering its physical state in response to appropriate synergistic stimulation by impinging radiation, particle bombardment or chemical reaction, information defining the object being structurally specified to reduce curl, stress and distortion in the ultimately formed object, the successive adjacent laminae, representing corresponding successive adjacent cross-sections of the object, being automatically formed and integrated together to provide a step-wise laminar buildup of the desired object, whereby a three-dimensional object is formed and drawn from a substantially planar surface of the fluid medium during the forming process.      A stereolithographic distortion known as curl is defined, and several techniques to eliminate or reduce curl are described, including dashed line, bent line, secondary structure, rivets, and multi-pass techniques. In addition, a quantitative measurement of curl known as the curl factor, and a test part known as a quarter cylinder are described, which together can be used to measure the effectiveness of the above techniques in reducing curl.

Abstract: The technical field of the invention relates to: (1) certain photosensitive substances used with lasers for discovery and destruction of tumors; (2) methods of making the substances; (3) use of the substances; and (4) certain light-delivery equipment used with the substance. To obtain tumor-selective, photosensitizing substances useful in the localization of neoplastic tissue and treatment of abnormal neoplastic tissue such as tumors, one of two methods is used. In the first method, a hydrolyzed mixture of the products of reaction of hematoporphyrin with acetic acid and sulfuric acid is cycled through a microporous membrane system to exclude low molecular weight products. In the second method, drugs are synthesized or derived from other pyrrole compounds. Other photosensitizing materials may be combined with a carrier that enters undesirable tissues and cells of the reticular endothelial system such as macrophages. These photosensitizing materials: (1) must have a triplet energy state above 3.5 kilocalories per mole; (2) cannot be easily oxidized; and (3) not physically quench any required energy state. Preferably, this photosensitizing material should be lipophilic. The substance is injected into the patient, clears normal tissue and then neoplastic tissue is irradiated using lasers. Laser equipment includes a light conductor and transmitting head with light differing surface and feedback path for radiated light related to dosage.

Title: Guard members for preventing shifting cargo from interfering with the operation of a roll-up door
Inventor: CLAY ROY T JR
IPC: B60J5/14
Filed: 1990-01-26
Granted: 1994-09-20
Abstract: This invention provides two forms of improved guards for a roll-up door. The first form (58 or 59) is intended to prevent shifting cargo from interfering with becoming interlocked with the lowered door. This form has a vertically-elongated guard which is adapted to overlie the vertically-spaced hinges, and has opposite marginal end portions closely spaced to the knuckle portions of such hinges. This first form reduces the stepped configuration of prior art hinges, and therefore reduces the opportunity for shifting cargo to become interlocked with the door. The second form (111) is mounted on the door and track, and is designed to prevent shifting cargo from entering the space through which the door must pass as it its raised or lowered.
