Patent number: 6422254Abstract: A hydraulic neutral cold start control valve for a variable displacement hydraulic unit includes a housing with a spool bore and an intersecting signal pressure passage therein. A spool is disposed in the bore and is mechanically biased to a closed or neutral position of the valve by a pair of opposing springs. A plunger is associated with one of the springs and has a surface that usually sealingly contacts one end of the spool but extends radially therebeyond such that it is in fluid communication with the signal pressure passage. When the signal pressure exceeds a threshold value, the pressure forces the plunger to separate from the end of the spool. Then the movement of the spool becomes proportional to the signal pressure, which is desirable for normal operation and control of the hydraulic unit.Type: GrantFiled: January 8, 2001Date of Patent: July 23, 2002Assignee: Sauer-Danfoss Inc.Inventor: James D. Ryken

Patent number: 6398035Abstract: A gravity separator with improved efficiency comprising a gravity table with pins at the feed area and a flow channeler. The pins create space in the bed of material to be separated which increases stratification of the weight fractions. The flow channeler creates flow paths of the fractions which do not cross and therefore the fractions do not slow each other from feed to discharge.Type: GrantFiled: April 17, 2000Date of Patent: June 4, 2002Assignee: Cimbria Heid GmbHInventor: Erich Vojtisek

Patent number: 6366192Abstract: A thick film low value high frequency inductor made by the process of subjecting a conductor layer to a plurality of linear cuts by a pulsing laser cutter imposed simultaneously on the entire length of the linear cut being made to create a cross sectional cut of substantial rectangular configuration. The conductor body is a layer of dried silver thick film ink. The method of making a thick film low value high frequency inductor involves the steps of taking a conductor layer comprised of a dried layer of photo sensitive silver ink, masking the ink with the negative of the desired configuration of the ink, exposing the ink to UV radiation, developing the ink, and firing the layer to adhere the silver to the layer.Type: GrantFiled: April 12, 2001Date of Patent: April 2, 2002Assignee: Vishay Dale Electronics, Inc.Inventors: Herman R. Person, Thomas L. Veik, Jeffrey T. Adelman

Patent number: 6345959Abstract: A fluid pump has a housing (4), a main output port (10), an auxiliary output port (14) and a priority pressure regulating valve contained with the housing (4). The priority pressure regulating valve has a spool (20) to direct fluid to one or both of the of the output ports (10,14), a force means (34,36) associated with the spool to bias the spool (20) to a position where it causes fluid to flow to the main output port (10) exclusively, and a pressure release means (40) which enables the spool (20) to move to a position where it permits fluid to flow to the auxiliary output port (14) when the pressure at the main output port (10) is at or greater than a predetermined pressure.Type: GrantFiled: August 17, 2000Date of Patent: February 12, 2002Assignee: Sauer-Danfoss (Swindon) LimitedInventor: Roderick Howell Spurry

Patent number: 6344180Abstract: Since glucagon-like peptide-1 (GLP-1) is the most potent insulinotropic hormone known and has been shown to stimulate insulin secretion strongly in patients with type II diabetes, this invention uses GLP-1 or its biologically active analogues in &bgr;-cell stimulatory tests in order to test &bgr;-cell function in a simple way. The test provides information about insulin secretory capacity, is easy and reproducible and has insignificant side effects.Type: GrantFiled: June 15, 1999Date of Patent: February 5, 2002Assignee: BioNebraska, Inc.Inventors: J. J. Holst, Tina Vilsboll

Patent number: 6338689Abstract: A hydromechanical transmission includes a hydrostatic transmission driven by an engine and drivingly connected to a planetary gear set. A plurality of clutches are associatable with the ring gear or elements of the planetary gear set for establishing a corresponding plurality of operating modes in which additional overall transmission speed can be achieved while reducing the power transmitted by the hydrostatic transmission. The gears of the planetary gear set can be removed and replaced with gears having a different number of teeth so as to change the overall ratio of the hydromechanical transmission without changing the power rating of the hydrostatic transmission or the size of the housing. Thus, multiple overall corner horsepower capabilities can be provided with the same hydrostatic transmission and housing package size.Type: GrantFiled: June 16, 2000Date of Patent: January 15, 2002Assignee: Sauer-Danfoss Inc.Inventor: Frederic W. Pollman

Patent number: 6338293Abstract: A reduced oil volume piston assembly for a hydrostatic unit includes a piston assembly having a piston body and a stem formed separately from the piston body. A cavity is formed in one end of the piston body. The stem includes an enlarged head and an elongated neck extending upwardly from the head. The neck lossely inserts into the cavity of the piston body so as to at least partially fill the cavity. The head is unattached to the piston body and cannot enter the cavity, but its shape allows fluid flow into the cavity around the stem. These components can be incorporated into the cylinder block assembly as separate components or the stems can be integrally cast with the cylinder block or attached thereto as a stem ring assembly.Type: GrantFiled: June 30, 2000Date of Patent: January 15, 2002Assignee: Sauer-Danfoss Inc.Inventors: Alan W. Johnson, Kenneth J. Woodshank, Michael A. Betz, Richard L. Otto

Patent number: 6336403Abstract: A fluid dampening system for a printing machine has a frame and a printing roll on the frame for holding a circular printing plate. A fluid reservoir is on the frame and a fountain roll is on the frame and is partially immersed in the fluid reservoir. A second roll is on the frame and is normally in surface contact with the fountain roll. A third roll is on the frame and is normally in surface contact with the fountain roll. A plurality of additional rolls are on the frame sequentially in surface contact with each other and with the third roll and the printing roll so that when all of the aforesaid rolls are rotated and in surface contact with each other, fluid will be transferred from the surface of the fountain roll to the surface of the third roll and sequentially on the surface of the additional rolls to the surface of the printing roll.Type: GrantFiled: April 5, 2000Date of Patent: January 8, 2002Assignee: Townsend Industries, Inc.Inventor: Jerry D.

Patent number: 6336325Abstract: A hydrostatic loop dump valve for reducing the starting torque required for a hydrostatic unit includes a normally biased open dump valve connecting one or more of the system pressure lines to the reservoir. The dump valve(s) will automatically open and oil will drain out by gravity when the engine is not running. When the engine turns the hydrostatic unit at sufficient speeds to generate significant charge pressure, the dump valves will close and the unit will operate as normal. Thus, the input torque required to start the engine and the hydrostatic unit is minimized without damaging the hydrostatic unit.Type: GrantFiled: December 7, 1999Date of Patent: January 8, 2002Assignee: Sauer-Danfoss Inc.Inventors: Steven H. Gluck, David K. Wohlsdorf

Patent number: 5856737Abstract: In an exemplary fast charging system, a hand-held computerized terminal with rechargeable batteries therein may be bodily inserted into a charger receptacle. The terminal may have volatile memory and other components requiring load current during charging. The system may automatically identify battery type and progressively increase charging current while monitoring for an increase in battery terminal voltage to ascertain the level of load current. The battery temperature may be brought into a relationship to surrounding temperature such that by applying a suitable overcharge current value and observing any resultant temperature increase, the level of remaining battery charge can be determined. For example, if the battery is found to be relatively fully discharged, a relatively high fast-charge rate may be safely applied while monitoring battery temperature.Type: GrantFiled: September 30, 1994Date of Patent: January 5, 1999Assignee: Norand CorporationInventors: Phillip Miller, Ronald D. Becker, Steven E. Koenck
