Title: Acoustical tuning device for gaseous automotive engines
Inventor: PETERS EDWARD W
IPC: F02M21/02
Filed: 1994-07-15
Abstract: ABSTRACT       A fuel supply system for a gaseous fueled automotive engine has means for damping pressure waves occurring within the fuel line between the fuel tank and the engine.  In a preferred embodiment, acoustical barriers, such as annular rings, are secured to the inside of the fuel rail for partially transmitting and partially reflecting the pressure waves so that wave amplitude is decreased.  An alternative embodiment comprises an acoustical barrier in the fuel line having a cylindrical section with a diameter larger than that of the fuel line. Baffles, possibly annular rings, within the cylindrical section also serve to damp the pressure waves.  The acoustical barrier may also be composed of a conical section with diameters equal to that of the cylindrical section on one end and the fuel line at the other end. Acoustical barriers placed in both the fuel line and the fuel rail also effectively damp the pressure waves.

Abstract: 2130082 9317093 PCTABS00025 Two nucleotide sequences encoding two different polypeptides found in yeast trehalose synthase have been isolated and cloned. A  third polypeptide has been isolated from the enzyme and characterized, and a method is provided to isolate and clone the nucleotide sequence encoding this polypeptide. The coding sequences can be inserted into suitable vectors and used to transform host cells.  The transformed cells will produce increased amounts of trehalose compared to the untransformed wild types and have increased tolerance to a variety of stresses, in particular to decreased availability of water. The invention may be used to improve the stress tolerance of organisms, to increase the storage life of foodstuffs and to produce trehalose economically on an industrial scale in an organism (e.g. baker's yeast) that is a traditional and safe foodstuff.

Abstract: A triaxial sensor substrate is adapted for use in measuring the acceleration and angular rate of a moving body along three orthogonal axes. The triaxial sensor substrate includes three individual sensors that are arranged in the plane of the substrate at an angle of 120 degrees with respect to one another. Each sensor is formed from two acclerometers having their sensing axes canted at an angle with respect to the plane of the substrate and further being directed in opposite directions. The rate sensing axes thus lie along three orthogonal axes. in order to to reduce or eliminate angular acceleration sensitivity, a two substrate configuration may be used. Each substrate includes three accelerometers that are arranged in the plane of the substrate at an angle of 120 degrees with respect to one another. The sensing axes of the accelerometers of the first substrate are canted at an angle with respect to the plane of the first substrate toward the central portion thereof so that they lie along three skewed axes. Similarly, the sensing axes of the accelerometers of the second substrate are canted at an angle with respect to the plane of the second substrate away from the central portion thereof so that they lie along same three but oppositely directed axes. The sensing axes of the first and second substrates are aligned to prevent angular acceleration sensitivity.

Abstract: A method and apparatus for stacking and conveying product units. The product units are conveyed on a conveyor from a loading station to an unloading station. The conveyor has a number of paddles extending therefrom where adjacentpaddles define receptacles between them for holding the product units. The invention allows the products to be reoriented while being conveyed from the loading station to the unloading station so that the products arrive at the unloading station with the desired orientation. This eliminates separate steps and apparatuses for conveying and reorienting. The present invention does this by first loading at least one product unit into the product receptacles and conveying the product units along the longitudinal axis of the conveyor. The paddles are then reoriented along a generally helical line while the products are being conveyed from the loading station to the unloading station. The paddles are reoriented to a desired angle with respect to the longitudinal axis of the conveyor. The product units are unloaded at the unloading station as a stack by removing the product units from a plurality of product receptacles. Thepaddles are then reoriented and returned to their original position as when they were loaded.

Inventor: OKAYAMA HIDEAKI
IPC: G02F1/11
Filed: 1995-08-23
Abstract: An optical wavelength filter has a polarizer, an analyzer, and an optical waveguide, formed in a substrate displaying an acousto-optic effect, that guides light from the polarizes to the analyzer. A transducer formed on the substrate excites a surface acoustic wave, thus creating an acoustic beam. The amplitude of the surface acoustic wave is small at the two sides of the acoustic beam and larger in the middle. The optical waveguide enters the acoustic beam at a point on one of the two sides of the beam, then moves into the center of the beam, and exits the beam at another point on one of the two sides.

Patent CA-2160410-A1 (CA)
Inventor: BRICKENSTEIN WOLF-JUERGEN
IPC: E06B3/22
Filed: 1995-10-12
Abstract: A description is given of a method for producing entire frames made up of plastic profiles  for outer frames and sash/leaf frames. This method consists in the fact that the outer-frame profiles and the sash/leaf-frame profiles are connected temporarily to one another with the aid of at least one interposed spacer piece, which compensates for the difference in the frame outer dimensions in the direction of the frame plane, and, in this assembled arrangement,  are jointly cut to size, welded  and,   if   appropriate,   finished.   In   this arrangement,  the same  (or another)  spacer piece also gives an additional distance between the frame profiles in the direction perpendicular to the frame plane, which additional distance, depending on the thickness of the frame profiles, is set to a range of from 3-10 mm.        The spacer piece may be designed as a small block and is, preferably analogously to the frame profiles, an elongate profile consisting of a thermoplastic material which does not undergo welding with the material of the frame profiles. Expediently, it has at least two parallel surfaces which come  to bear on the outer  frame and sash/leaf frame, between two mutually parallel surfaces of the outer frame and of the sash/leaf frame, and retain the frames at a predetermined distance from one another.        The  temporary  assembled  arrangement  of  the profiles and the spacer piece is produced by means of a shrink film or of a corresponding auxiliary means, which can be easily removed after the entire frame has been finished.

Title: Flexible runner sled
Inventor: OLIVIERI BENSON H
IPC: B62B13/12
Filed: 1995-12-12
Abstract: Described herein is a coaster having a pair of longitudinally-extending and laterally-spaced flexible sled runners which support and define a path for the coaster along a ground surface. The coaster includes forward, intermediate, and rearward lateral struts extending between the flexible runners. The flexible sled runners extend forward from the forward lateral strut to leading rail ends. A longitudinally-extending body support board is mounted above the runners in sucha manner as to allow it to pivot or tilt, relative to the flexible sled runners,about a longitudinal axis. A steering handle is operably connected to the leading rail ends to laterally displace the leading rail ends and to thereby arcthe flexible sled runners. Interlinkage between the steering handle and the bodysupport board pivots the body support board in response to turning the steering handle. Gearing associated with the body support board and the intermediate lateral strut laterally displaces the intermediate lateral strut relative to theforward and rearward lateral struts in response to pivoting the body support board relative to the flexible sled runners. This displacement further arcs the flexible sled runners and thereby curves the path of the coaster.
