Title: Continuously variable hydrostatic transmission with neutral-setting hydraulic circuit
Inventor: PRUCELL DONALD MARK
IPC: F16H39/10
Filed: 1996-07-31
Abstract: A continuously variable hydrostatic transmission includes axially aligned input (14) and output (16) shafts journaled by a transmission housing (12) and respectively coupled to a prime mover and a load. The input shaft (14) drives a hydraulic pump unit (18) while a hydraulic motor unit (20) is grounded to the transmission housing (12). A wedge-shaped swashplate (22) is pivotally connected to the output shaft (16) in operative position to accommodate pressurized hydraulic fluid exchanges between the pump (18) and motor (20) units. A controller (24) is coupled to adjust the angular orientation of the swashplate (22) relative to the output shaft axis (35) and thus set the transmission ratio. A hydraulic circuit (26), connected into the hydraulic motor unit (20), is selectively operable to vent high and low fluid pressure sides of the swashplate (22) to atmosphere, thus imposing a neutral transmission ratio condition regardless of the transmission ratio set by the controller (24).

Title: Improved method for optimization of the grain refinement of aluminium alloys
Inventor: B CKERUD STIG LENNART
IPC: C22C21/00
Filed: 1996-11-21
Abstract: The invention is a method of controlling the grain refinement of certain aluminium alloys. The grain sizes for different values of the grain growth index, GGI, are determined for the used casting method. The GGI  is represented by the sum of m(k - 1) value multiplied with the concentration for every element in the aluminium alloy. If the value for a certain alloy is compared with known relations between the m(k - 1) value and the grain size the composition of the alloy melt is amended to an optimum grain size by adding a grain size affecting agent. The method can be further improved by optimising the amount of nucleating agent.

IPC: C12Q1/6825
Filed: 1997-04-24
Abstract: A method and apparatus for the manipulation of colloidal particulates and biomolecules at the interface between an insulating electrode such as silicon oxide and an electrolyte solution. Light-controlled electrokinetic assembly of particles near surfaces relies on the combination of three functional elements: the AC electric field-induced assembly of planar aggregates; the patterning of the electrolyte/silicon oxide/silicon interface to exert spatial control over the assembly process;  and the real-time control of the assembly process via external illumination. The present invention provides a set of fundamental operations enabling interactive control over the creation and placement of planar arrays of several types of particles and biomolecules and the manipulation of array shape and size. The present invention enables sample preparation and handling for diagnostic assays and biochemical analysis in an array format, and the functional integration of these operations. In addition, the present invention provides a procedure for the creation of material surfaces with desired properties and for the fabrication of surface-mounted optical components.

Abstract: A process for producing phosphinopyrrolidine compounds especially useful for preparing optically active compounds through asymmetric synthesis which is a simplified short process requiring neither a step necessitating a high-temperature and high-pressure reaction nor special equipment for production. A  phosphino group is incorporated into a pyrrolidine compound in the presence of a boron compound, and the resultant pyrrolidine compound is further reacted while protecting the phosphorous atom, whereby a dicyclohexylphosphino group can be efficiently incorporated into the pyrrolidine nucleus in the 4-position. Thus, the target phosphinopyrrolidine compounds useful as a ligand for an asymmetric synthesis catalyst can be obtained through a significantly small number of steps without resort to troublesome steps such as the step of reducing a phenyl group at high temperature and high pressure.
