Abstract: A closed loop, carbon monoxide self-contained continuous process for the production of nickel or nickel coated objects by the nickel vapour deposition process, comprising placing an object to be treated with nickel carbonyl by said nickel vapour deposition process in a deposition chamber; feeding a gaseous mixture of nickel carbonyl and carbon monoxide to said deposition chamber; depositing nickel on said object to produce said nickel or nickel coated object in said chamber and a nickel carbonyl-depleted gaseous mixture; removing said nickel carbonyl-depleted gaseous mixture from said chamber; removing nickel carbonyl from said nickel carbonyl-depleted gaseous mixture to produce an essentially nickel carbonyl-free gas; feeding said essentially nickel carbonyl-free gas to a nickel carbonyl reactor containing nickel powder to produce a fresh gaseous mixture comprising fresh nickel carbonyl and carbon monoxide; separating said fresh nickel carbonyl from said fresh gaseous mixture to produce a second carbonmonoxide containing gas; and recycling said second carbon monoxide containing gas to said nickel carbonyl reactor. The process and apparatus provides a more economic to operate, safe and more operably reliable than prior art NVD processes.

Abstract: This invention involves user mode proxy of kernel mode operations in a computer operating system. The broad contours of the invention allow drivers operating in the kernel mode of an operating system to be proxied by a corresponding user mode object. A user mode process wishing to communicate with or manipulate the kernel mode driver may perform such communication or manipulation by communicating with or manipulating the corresponding user mode proxy. The present invention has particular applicability to emerging operating systems which allow kernel mode drivers to be interconnected in order to create a processing stream in the kernel where data is passed from kernel mode driver to kernel mode driver without transitioning to user mode. User mode proxy of such kernel mode drivers allows user mode processes to manipulate such kernel mode drivers using familiar user mode protocols without the necessity of learning new kernel mode protocols.

Abstract: A connection for adjustably holding a sash arm and a support arm in pivotally connected relationship, including a sash arm having a first cylindrical opening, a support arm having a second cylindrical opening at one end, and a stud.  The study includes a pivot portion with a cylindrical shaft extending through the second cylindrical opening, a rivet portion extending from on end of the cylindrical shaft through the first cylindrical opening and eccentric to the pivot portion cylindrical shaft, and a head on an end of the rivet portion spaced from the cylindrical shaft wherein the head and the one end of the cylindrical shaft engage opposite sides of the sash arm to frictionally secure the stud against pivoting relative to the sash arm.  The first cylindrical opening includes a countersunk hole on the side of the sash arm attachable to a window sash, wherein the rivet portion head is formed substantially entirely in the countersunk hole.  A plastic washer is disposed about the cylindrical shaft between the sash arm and support arm, and has an outer diameter which is less than the width of the sash arm and support arm.  A hexagonal shaped aperture is formed on the shaft head and is engageable with an L-shaped hex wrench to allow for adjustment of the pivotal connection by pivoting the stud between frictionally secure positions relative to the sash arm.

Abstract: A method of operating a target system wherein small changes in input variables produce small changes in output variables in a manner permits system learning on a time dependent basis. The rate of change of the system output is directly dependent upon the product of the rate of change of the system input and a matrix consisting of input variables and antecedent and consequent parameters. A preferred performance criterion is obtained through the approximation of the said matrix to a weighted-augmented pseudo-inverse Jacobian. Off-line, the system undergoes a series of iterations using a wide range of input variables wherein the actual outputs are compared to the desired outputs and optimized values for the antecedent and consequent parameters are obtained and passed back to the said matrix for use in the subsequent iteration.
