Title: Aldehyde-based surfactant and method for treating industrial, commercial, and institutional waste-water
Inventor: GALANTE DENISE CHRISTINE
IPC: C09K23/00
Filed: 1996-05-10
Abstract: A nonionic surfactant having cyclic 1,3-dioxane and/or 1,3-dioxolane functionality is irreversibly splittable by lowering the pH of its aqueous solution. The cyclic 1,3-dioxolane has the formula:   (see figure I) The 1,3-dioxolane has the formula:   (see figure II) of which R is hydrogen and R' has no alkoxy linkage and is the residue of an organic compound (substituted or unsubstituted) derived from an aldehyde of the formula (see figure III) wherein R is hydrogen and R' is the residue of an organic compound (substituted or unsubstituted) which contains a total of 8 to 20 carbon atoms and which contains no moieties or linkages which significantly interfere with the performance of the surfactant for its intended purpose; X is hydrogen or the residue of a hydrophobic end-cap; Y is hydrogen, methyl, ethyl, or mixtures thereof; Z is hydrogen, methyl, or ethyl; m is 0 or 1; and n is an integer of 1 to 40. After splitting of the surfactant into its components aldehyde and polyol, the hydrophobic components phase-separate and can be removed from the aqueous stream by routine means. The nonionic surfactant is useful in various processes requiring the removal of emulsified hydrophobic contaminants or other hydrophobic materials from an aqueous stream.

Title: Pedal mechanism for cycle and exercise equipment
Inventor: TORONTO SALVATORE
IPC: B62M1/24
Filed: 1995-02-02
Abstract: A pedal mechanism for a bicycle to permit a forward force to be applied to the drive wheel (10) by backward rotation of the pedals (2, 3) in addition to permitting a forward force to be applied to the drive wheel by a forward rotation of the pedals (2, 3).  A preferred embodiment allows one of the pedals (2, 3) to be rotated in one direction while the other pedal (2, 3) rotates in the opposite direction. A free-wheeling clutch (17) is positioned between the pedal shaft (6) and the bevel gear (16). When the pedal shaft (6) is rotated in the forward direction, the free-wheeling clutch (17) engages and causes bevel gear (16) to impart a forward force to the drive wheel (10). When the pedals are rotated in the reverse direction, the free-wheeling clutch (18) engages causing bevel gear (19) to rotate with the pedal shaft which permits a forward force to be applied to the drive wheel (10) by reversing gear (20). Free-wheeling clutches (17, 18) engage the pedal shaft (6) to provide unidirectional movement of the drive wheel (10) when the pedals are rotated in either the forward direction or the reverse direction.

Title: Transgenic non-human mammals with progressive neurologic disease
Inventor: HSIAO KAREN
IPC: A01K67/027
Filed: 1995-01-27
Abstract: Provided is a transgenic non-human eukaryotic animal whose germ cells and somatic cells contain the amyloid precursor protein sequence introduced into the animal, or an ancestor of the animal, at an embryonic stage. In mice, an age-related CNS disorder characterized by agitation, neophobia, seizures, inactivity, diminished cerebral glucose utilization, cortico-limbic gliosis, and death, develops. An acceleration of this disorder occurs in transgenic mice expressing human and mouse Alzheimer amyloid precursor proteins (APP) produced using a hamster prion protein gene-derived cosmid vector that confers position-independent, copy number-dependent expression. In transgenic mice the disorder develops in direct relationship to brain levels of transgenic APP, but mutant APP confers the phenotype at lower levels of expression than wild-type APP. The disorder occurs in the absence of extracellular amyloid deposition, indicating that some pathogenic activities of APP are dissociated from amyloid formation.

IPC: A61M11/06
Filed: 1996-11-13
Abstract: An endotracheal catheter assembly and method for deep intrapulmonary, aerosol delivery of liquid drugs and other liquid therapeutic agents. The invention can deliver a bolus dose of liquid drugs into the lungs of a patient which is at least bioequivalent in terms of physiological effect to a similar drug dose delivered intravenously. The catheter assembly includes a first, gas-bearing tube and a second, liquid bearing tube, preferably concentrically nested within the gas-bearing tube. The tubes are inserted in an airway of the patient, preferably by threading the tubes into a lumen of an endotracheal tube, to position a terminal nozzle formed by distal tips of the tubes near a carina of the patient. At the nozzle, the lumen of the first tube has a comparative cross-sectional area relative to that of the second tube's lumen of between about 0.4:1.0 and 4.0:1Ø In operation, high velocity gas is forced from the first tube and impacts liquid expelled from the second tube at a high velocity gas/liquid interface, deforming the liquid into an aerosol and propelling it deep within the lungs of the patient.

Abstract: On multiplie des signaux des voies du signal I et Q par des répliques de codes (24) d'étalement de spectre et les produits ne sont intégrés que sur une période (25) du code d'étalement de spectre. On élimine des composantes de données modulées et de fréquence porteuse résiduelle en soumettant les signaux intégrés (26) à une détection quadratique d'amplitude. La puissance de signal de la somme des signaux (27) soumis à cette détection quadratique d'amplitude est constatée pendant une période de code d'étalement du spectre (actualisant la phase d'horloge d'un générateur d'horloge de commande numérique (30)) et chaque information de puissance est stockée dans un circuit de mémoire d'un circuit de commande (29) de mode synchrone initial. La phase d'horloge du générateur (30) est fixée lorsque la phase de la réplique de code d'étalement du spectre est à la puissance détectée à corrélation maximum pour une période de code d'étalement du spectre. Un mode de confirmation de phase synchronisée du code à étalement du spectre est alors activé. Le mode de confirmation de synchronisation du code d'étalement du spectre étant assuré par ce moyen, une synchronisation initiale est établie avec une faible probabilité d'erreur de synchronisation et un mode de poursuite est rapidement activé.

Operational amplifiers and modulators modulate the compensating power with signals derived from the signal source such that the modulated compensating power is the complement of the modulated RF drive power. A summer combines the modulated RF drive power and compensating power to drive the acoustooptic device such that the spatial thermal energy distribution inside the acoustooptic device remains substantially constant.
