Title: Coupling assembly
Inventor: LATSKO JAMES MICHAEL
IPC: F16D13/46
Filed: 1992-11-04
Granted: 1999-04-13
Abstract: A coupling assembly includes a clutch assembly and a brake assembly.  The brake assembly includes an annular piston which is formed as one piece with a base member.  An annular cylinder chamber is formed as one piece with a second  member and telescopically receives the annular piston.  Force transmitting surfaces on the two members engage opposite sides of a friction disk.  The annular piston and cylinder extend around the outside of the friction disk to at least partially block a flow of contaminants in a radially inward direction toward the friction disk.  Passages are formed in a lower portion of the annular piston to accommodate a flow of cooling fluid and to enable any contaminants which enter the brake assembly to flow out of the brake assembly.  The brake assembly is advantageously urged to an engaged condition by spring assemblies which include posts and spring elements which extend into a space between the clutch assembly and a flange portion of a flywheel.  Arcuate spring retainer elements extend between outer end portions of the posts to hold the spring elements in place on the posts.  The clutch assembly is operated from a disengaged condition to an engaged condition by fluid pressure conducted from the brake assembly.

Title: Compensation mechanism for a pressure sensor
Inventor: KEMP STEPHEN J
IPC: G01L7/08
Filed: 1992-12-30
Granted: 2003-12-02
Abstract: A differential pressure sensor with a compensation means, said differential pressure sensor comprising the diaphragm with a first means having a mass mounted upon the diaphragm. The first means is utilized to determine the position of the diaphragm relative to an initial first position and/or to increase the effective area of the diaphragm. A housing contains the diaphragm, the housing has a first and a second inlet port. The first inlet port provides a first pressure to a first side of the diaphragm and the second inlet provides a second pressure to the second side of the diaphragm, the diaphragm moving to the lesser of the two pressures. A counterweight mechanism is located in the housing having a inner arm and an outer arm. The counterweight mechanism pivots about an axis. The center of gravity of the counterweight mechanism is located on the outer arm. The inner arm is in contact with the first means, whereby the counterweight mechanism compensates for the mass added to the diaphragm which enables the pressure sensor to be mounted in any orientation.

Title: Use of pharmaceutical compounds in the treatment of symptoms of disorders related to neurological diseases and etiologically related symptomology
Inventor: SHAPIRO HOWARD K
IPC: A61K8/49
Filed: 1992-02-21
Granted: 2004-05-11
Abstract: The invention regards a novel use of pharmaceutical compositions in treating symptoms of disorders relating to neurological diseases and for treating pathophysiologicially related symptomology in other body tissues, including peripheral neuropathies, secondary symptomology of diabetes, Alzeheimer's disease, Parkinson's disease, alcoholic polyneuropathy and age-onset symptomology. Covalent bond crosslinking of protein and lipid subcellular elements appears to underlie the formation of polymerized aggregates of neurofilaments, other structural proteins and lipofuscin. The use of certain compounds may compete with cellular protein and lipid amine groups for reaction with disease-induced carbonyl-containing aliphatic and aromatic hydrocarbons. Such derivatized pharmacological agents can then be excreted by the kidneys, thus removing the toxic agent(s). The presence of an acid functional group on the agent used facilitates kidney recognition and removal. Another application of the present invention includes the oral use of non-absorbable polyamine agents such as chitosan to covalently bind and sequester potentially toxic carbonyl compound present in the diet.  Veterinary, food processing and cosmetic applications of the present invention are also described.

Granted: 1996-08-06
Abstract: A locking/release mechanism for a pivot bolt of a closed-circuit door opener with a safety catch for the pivot bolt is controlled by an electromagnet. In order to reliably ensure a release of the pivot bolt, even if strong pressure has been exerted thereon prior to the cessation or interruption of the magnet current, a locking lever is positioned between the electromagnet and the safety catch. The locking lever has a two-armed construction, one arm being provided with a stop member for engagement with the safety catch and the other arm being in the form of the electromagnet armature. The effective contact surface between the safety catch and the stop member is constructed in such a way that the safety catch applies a cam-like displacement action on the stop member.

Title: Pompe avec plusieurs stages de pompage distincts pour pomper plusieurs liquides
Inventor: COTE DENIS
IPC: F04D13/14
Filed: 1993-10-07
Granted: 1998-01-06
Abstract: La pompe comporte trois séries distinctes de stages de pompage entraînées sur un seul arbre par un même moteur. Entre les première et deuxième séries de stages de pompage, le liquide est acheminé en dérivation hors de la pompe dans la direction, par exemple, d'un dispositif de filtrage visant à retirer du liquide le plus d'impuretés possible. Ensuite, le liquide filtré est retourné vers la deuxième série de stages de pompage de la pompe où le liquide est pompé à haute pression avant d'être acheminé en dérivation hors de la pompe en direction d'une enceinte de traitement, notamment où s'effectue une osmose inverse, une nanofiltration ou autre. Le perméat est retiré de l'installation tandis que le soluté est, en grande partie, recirculé vers une troisième série de stages de traitement, à la sortie de laquelle il se mélange avec le liquide filtré en provenance de la deuxième série de stages et le tout est alors acheminé de nouveau vers l'enceinte de traitement. Ce système à très bon rendement permet l'économie d'une deuxième et d'une troisième pompes. La pompe peut également être utilisée pour pomper de façon indépendante, i.e. sans mélanges, plus d'un liquide. Dans ce cas, les stages de pompage sont encore une fois séparés les uns des autres et chaque stage pompe son liquide respectif. Les stages peuvent pomper des liquides à différents débits et à différentes pressions.

Abstract: A window operator handle foldable between an operable posi-tion for manual pivoting and a storage position, including a body with a manually graspable portion at one end and a recess in the other end, and a base including a longitudinal cylindrical portion having a central bore extend-ing completely through the base. The handle body recess is defined by side walls spaced a selected width, a top wall, and a wall at one end oriented substantially parallel to the operator drive shaft when the handle is in the operable position, with the base cylindrical portion having an outer diameter slightly less than the selected width. An operator drive shaft is securable in the base bore so that the an outer end of the drive shaft is substantially adjacent the handle body when the handle is in a storage position. The handle base is secured for pivoting relative to the handle body about an axis substantially orthogonal to longitudinal whereby in the storage position the base is substantially within the handle body recess. The body top wall serves as a stop for pivoting of the base relative to the body when the handle is pivoted to the storage position and the body end wall serves as a stop for pivoting of the base relative to the body when the handle is pivoted to the operable position. A detent on the handle base is sharply tapered at one end, with the detent itself being narrower than the recess selected width by a selected amount. A detent spring has two legs connected at one end by a spring base secured at the other end of the handle body. In an unbiased position, the other ends of the spring legs are spaced apart less than the width of the detent, with those leg ends having a total width which is less than the selected amount and engaging the detent tapered end when the handle is in the operable position.
