Title: Counterthrust seal for a rotary fluid machine
Inventor: BEAR CLAYTON
IPC: F04D29/12
Filed: 1992-08-07
Abstract: Counterthrust Seal For A Rotary Fluid Machine ABSTRACT OF THE INVENTION     Rotary fluid machines such as gas compressors generally comprise a housing containing a duct and a rotor which rotates within the duct. The rotor includes at least one impeller which contacts the fluid passing through the duct. Axial forces are imposed on the rotor by the fluid due to the momentum of the fluid and the pressure differentials within the duct. This invention provides a counterthrust seal assembly disposed between the rotor and the housing to inhibit the escape of fluid out of the duct at the point where the rotor passes through the housing and is operable to apply a variable force to the rotor to counteract the axial forces due to the fluid passing through the duct. The counterthrust seal assembly is formed from three fluid seals assembled in series wherein the seals have different effective sealing diameters. A first and second piston chamber are formed between the seals due to the difference in effective sealing diameters. By modulating the pressure within the piston chambers the magnitude and axial direction of the force applied to the rotor by the counterthrust seal assembly can be varied.

IPC: C10G35/16
Filed: 1992-04-08
Abstract: Divulgation d'un dispositif électrique pour la conversion de molécules d'un certain poids moléculaire en molécules d'un autre poids moléculaire. On utilise un réacteur contenant une série de dynodes, chacune d'elles possédant plusieurs ouvertures. On produit un champ électrique en appliquant de l'extérieur une tension entre les dynodes. Lors du fonctionnement, des électrons et des ions frappent les surfaces intérieures des ouvertures des dynodes, ionisant les molécules adsorbées à la surface. Celles-ci sont désorbées sous l'impact, puis accélérées par le champ électrique vers un autre endroit sur la surface de la dynode, où elles se combinent à des molécules adsorbées pour former une variété de nouvelles molécules plus lourdes ou plus légères. Certains des ions produits subissent plusieurs déplacements et atteignent une extrémité du dispositif, où ils peuvent être pompés sélectivement. L'ionisation ayant lieu dans le dispositif, contrôlée par l'impact des électrons ou des ions, peut aussi conduire à des réactions entre plusieurs espèces moléculaires qui seraient improbables ou impossibles dans des conditions normales d'équilibre chimique ou en présence de catalyseurs courants.

Title: Lawn mower height-adjust systems
Inventor: HESS KRISTOFFER A
IPC: A01D34/74
Filed: 1991-04-24
Abstract: ABSTRACT OF THE DISCLOSURE     Lawn mower height-adjust systems include three embodiments.  Two permit the user to adjust the position of the deck relative to each wheel individually.  The third permits the user to adjust the positions of all four wheels simultaneously, aided by a counterbalance system.  A modification of the third embodiment is available to automatically bypass the height-adjust mechanism in the event an abnormally high load is placed on the deck.  One of the two individual systems permits an operator to adjust the position of a respective wheel simply by removing a single nut and washer from an axle bolt.  The second individual height-adjust system permits the operator to adjust the height of an individual wheel by using one hand, and without having to disassemble the mechanism.  The system which adjusts all four wheels simultaneously links front and rear axle subassemblies with a connecting rod, and indexes a11 four wheels simultaneously through a release handle which is recessed in a cavity formed in the lawn mower deck.  When the operator lifts the release handle, he or she may simultaneously grasp a portion of the deck with the same hand and easily raise or lower it to a desired position. A single unitary plastic deck is the foundation for each of the three height-adjust systems, thereby significantly reducing the cost otherwise incurred by manufacturing three separate types of lawn mowers.

Title: Electroconductive article, method of producing same, and motor produced from the article
Inventor: KANAI HITOSHI
IPC: H02K17/18
Filed: 1993-03-05
Abstract: An electroconductive material has at least one portion in which the electrical resistance varies continuously along a gradient.  Accordingly, since the material is not formed by directly bonding different elements, it does not have a weak joint portion. Further, since other material characteristics basides electrical resistance also vary along a gradient, for instance, when the material is used at a high or low temperature, a large thermal stress does not generate at an interface between different elements of the material due to a difference of thermal expansion coefficients of such elements.   A method of producing an electroconductive material comprises the steps of adding and additive to a base material, producing plural alloy materials having different compositions, respectively, overlapping the produced plural alloy materials, and joining the overlapped materials by plastic processing. A motor uses the above electroconductive material as a conductor provided in a plural slots.  Consequently, starting characteristics of the motor are improved due to the skin effect, and internal stress of the motor due to the thermal expansion of the conductor is decreased. Moreover, the reliability of the motor is improved.
