Title: Lube oil system for rotating machinery
Inventor: KIMBERLIN ROBERT R
IPC: F16N7/36
Filed: 1990-04-06
Granted: 1995-03-28
Abstract: A device is provided for the circulation of fluid through and about the rotary shaft of a rotating piece of equipment.  The circulation is induced by a plurality of radially extending passageways from a center bore in the rotor shaft which extend to the external periphery of the shaft.  Rotation causes the center of the shaft to be evacuated by pumping action created by the radial slots thereby producing a lowered pressure area producing a circulation path axially along the outside periphery of the shaft in one direction and axially along an internal through bore in the shaft towards the other end containing the radial slots. Bearings for mounting the shaft being disposed about the outer periphery of the shaft are thereby provided with lubrication and a cooling flow of fluids.

Abstract: ABSTRACT VEHICLE SYSTEMS FOR USE IN   COSMETIC COMPOSITIONS Disclosed is a unique vehicle system which provides a desir-able rheology to products formulated therewith, enhanced disper-sion  of  actives  therein,  and  improved  deposition  of  actives therefrom.  This vehicle system comprises  a primary thickening agent  which  is  a  nonionic  long-chain  alkylated  water-soluble polymer, and a secondary thickening agent which is a water-soluble polymer  having  a molecular  weight greater  than  about  20,000, preferably a natural  polysaccharide,  dispersed in a compatible solvent.   Optionally, a rheological  aid,  which is a  chelating agent, may be included in the vehicle system.  Also, optionally, a distributing aid, which is a water-soluble polymer of either high molecular weight or strong ionic character may be included in the vehicle  system.   These vehicle  systems  are useful  in  cosmetic compositions which are used to deliver an active component to the skin or hair.  The vehicle systems are particularly useful in hair care compositions, especially rinse-off hair conditioning composi-tions,  because they effectively deliver  the hair conditioning component to the hair without depositing a substantial amount of the vehicle material onto the hair.

In further drawer chambers (2) and (4) which are open towards the front of the device housing (1) there can be arranged a controller drawer (3) having a second electronic controller unit which is identical to the first controller unit and a power-pack drawer (5) having a second power pack which is identical to the first power pack, which can be connected by lines both to each other and to connection contacts (31) for external connections.  The first controller unit can be supplied with power by the first power pack and the second controller units supplied with power by the second power pack.  Input signals can be fed to both controller units simultaneously in parallel from the outside via the lines and can be processed synchronously by both controller units.  Depending on the processing of this signal and the status of the controller units, output signals can be produced exclusively by one of the controller units.

Abstract: A biologically active composition made up of core particles having diameters  of less  than about  1000 nanometers  which are coated with  a  layer which  is designed to allow attachment of biologically active proteins,  peptides or pharmacological  agents to the microparticles.  When viral protein is attached to the core  particles,  the  result  is  a  viral  decoy which accurately mimics the native virus in both size and structure  while  being  entirely  devoid  of  virulent activity due to the microparticle core.  Other antigenic proteins or peptides are attached to provide molecules which  are  useful  in  raising  antibodies  or  as  a diagnostic tool.   Further, pharmacological agents are attached to the microparticles to provide pharmaceutical compositions.  The viral decoys are useful as vaccines for treating animals to elicit an immune response.

Title: Automatic trolling arrangement
Inventor: KULPA DANIEL S
IPC: G05D1/02
Filed: 1991-07-03
Granted: 2001-06-12
Abstract: Automated constant depth steering and automated yaw correcting techniques for fishing boats or similar craft usable in concert or separately are disclosed. The constant depth steering arrangement controls a relative constant thrust electric trolling motor by varying the orientation of this trolling motor which propels the boat relative to the boat. The constant depth steering arrangement includes operator entry switches and potentiometers for receiving an operator selected water depth and an indication of the direction and sense in which water depth changes. The automatic yaw correcting arrangement includes a rudder-like structure for sensing the lateral component of craft motion relative to the water, and is responsive to the sensed lateral motion to imparting a lateral thrust to the craft in opposition to the sensed lateral component of craft motion.      The lateral thrust may be provided by a reversible motor such as another trolling motor mounted to the craft with its thrust axis transverse to the craft, and the sensing arrangement, in addition to the rudder may include a normally open switch coupled to the rudder and closable in one of two positions when the lateral component of craft motion exceeds a prescribed threshold, the one closed position being indicative of the direction of lateral motion and, therefore, the direction in which the reversible motor must be energized to appropriately compensate.

The control system includes a central processing unit (106) for receiving input signals indicative of transmission input shaft (16) and output shaft (90) speeds and from a driver control console (108) indicative of manual selection of upshifts or downshifts from a currently engaged gear ratio, or manual selection of operation in an automatic preselect mode, and processing the same in accordance with predetermined logic rule to issue command output signals to a transmission actuator (112, 70, 96) to implement the selected shifts by automatic shifting into neutral upon a naturally or manually caused torque reversal of the transmission and remaining in neutral until the vehicle operator causes substantially synchronous conditions to occur.  The method (200) includes sensing if output shaft speed remains substantially constant and the transmission is not shifted (Shift = F) for a predetermined time (REF) and then causing the system to operate in the manually selected shift mode of operation.

Title: Camshaft adjuster and tensioner
Inventor: ARNOLD GERD
IPC: F16H7/08
Filed: 1991-12-23
Granted: 1994-05-24
Abstract: CAMSHAFT ADJUSTER AND TENSIONER Abstract A camshaft adjuster mounted between a taut strand and a slack strand of a chain connecting an intake camshaft to an exhaust camshaft has two tensioning shoes which are urged by a spring away from each other and against the inner sides of the chain strands.  One tensioning shoe is mounted on a reciprocable piston within which a plunger carrying the other tensioning shoe is slidable against the force of the spring.  The piston is moved against the taut strand by pressurization of a pressure chamber through a nonreturn valve and the plunger is moved with the piston so that the taut and slack strands are moved together and compression of the tensioning spring is thereby maintained relatively constant.  A damping chamber may be provided with throttling bores in the piston and/or plunger to control the damping effect.
