Abstract: The invention relates to compositions for use in animal models of neurodegenerative disease and methods therefor. More particularly, the invention relates to the use of neurotoxic sterol glycosides or neurotoxic glycolipids, or combinations thereof, in animal models of neurodegenerative disease. Neurotoxicity-modulating chromenols can also be used in these animal models in combination with the neurotoxic sterol glycosides or neurotoxic glycolipids, or combinations thereof.

Abstract: A method for preserving orientation information in an image may comprise: collecting image data, including orientation information inherent to collecting the image data; and embedding in the image data an orientation mark unambiguously identifying when the image data is presented in a correct viewing orientation. Image data is stored in a medium together with data forming an embedded orientation mark which is bilaterally asymmetrical in at least two orthogonal axes. In a variation, the data forming the embedded orientation mark further comprises at least one humanly recognizable text or punctuation character, word or trademark.

Abstract: A radiation-recording plate (104) can be constructed and arranged to form an image upon exposure from both a front side and a back side. The plate can include a marker (201) detectable in the image (205) after exposure and indicative of which of the front side and the back side the plate is exposed from. The marker may comprise a medium opaque to the radiation coating a region that does not interfere with reading the image when the plate is exposed from either side, or may be a void in the sensitive layer of the plate. The marker may have horizontal asymmetry about a vertical axis relative to a normal image orientation, or the marker may have vertical asymmetry about a horizontal axis relative to a normal image orientation. The marker may further comprise a front side marker and a back side marker whose appearance in an image on the plate indicates exposure from the front side or the back side respectively.

Abstract: A viscous liquid dispenser, comprising a pump mechanism; a supply reservoir; and an extension hose having an adapter end adapted to connect to the pump mechanism and having an uptake end disposed within the supply bottle, to deliver the liquid from the supply reservoir to the intake tube, the supply reservoir otherwise unattached to the pump mechanism. A viscous liquid supply system for delivering liquid to a pump mechanism, comprising a supply reservoir adapted to hold a supply of liquid; and an extension hose having an adapter end adapted to connect to the pump mechanism, the supply reservoir remaining unattached to the pump mechanism while in use, and the extension hose having an uptake end disposed in contact with the supply of liquid.

Abstract: A flow restrictor to minimize noise and cavitation, or other adverse effects, in regulating the flow of a high pressure fluid. The restrictor defines a myriad of tortuous, dissimilar, intertwined, and commingled energy dissipating chambered flow paths edgewise through a stack of sheets of perforated stock material. Adjacent sheets have their perforations out of registration with one another, the inlet and outlet to the restrictor being edgewise through the stack through open-sided ones of the perforations of the several sheets of stock.

Abstract: A fluid flow restrictor for spanning a passage of a body to minimize noise and cavitation in a high pressure fluid flowing through the passage and undergoing a substantial pressure drop in passing through the restrictor. The device comprises at least one tier of fixed perforated tubelets defining a myriad of tortuous flow paths with restricted orifices and expansion areas to dissipate energy in the fluid. The fluid flow through or between individual tubelets may be further subdivided into restriction orifices and expansion areas by additional fixedly held solid elements, e.g., BB shot tightly packed within the tubelets. The preferred inventive embodiment described is a sound suppressing, high pressure reducing poppet valve having several tiers, isolated from one another, of annular clamped arrays of parallel perforated tubelets.

Abstract: A sound suppressing fluid handling device wherein a relatively high pressure fluid is conducted through a substantial pressure drop, relatively noiselessly, by passage of the fluid through a myriad of tortuous energy dissipating passages formed between adjacent turns of and opening through the ends of a sound suppressing reel comprising a relatively thin flexible spirally wound band. The preferred inventive embodiment described is a valve comprising a stack of annular discs seating coaxially against the inlet end of the sound suppressing reel and containing passages, formed partly between adjacent discs, for conducting the incoming high pressure fluid from the central opening in the disc stack to the inlet ends of the reel passages.
