Patent DE-112007003585-A5 (DE)
Inventor: DZAFIC IZUDIN
IPC: H02J3/18
Filed: 2007-05-07
Abstract: A method allows determining load flow in a symmetrical electrical supply grid, particularly a symmetrical electrical distribution grid having asymmetrical loads. The load flow is typically solved within an electrical supply grid by means of an extensive matrix system. The determination of power, voltage, and current at certain node points in the electrical supply grid leads to a large matrix to be solved, which previously had to be solved in whole using algebraic means. By converting the matrix to symmetrical space vector components that can be used to monitor the phase progression of the space vector components, it becomes possible to divide the entire matrix into partial matrices and thus to be able to calculate the partial matrices faster and in parallel using a computer system.

Title: System for the railway transport of semi-trailers.
Inventor: WALDA FEDDE
IPC: B65G67/02
Filed: 1986-07-04
Abstract: A railroad freight car having a rotatable loading floor for transferring loads between it and a station platform. The railroad station has two platforms on opposite sides of the rail car. An edge of each platform is provided at each longitudinal end with a sloping beam which angles upwardly from the end of the platform towards its center. The lowest part of the beam, which is at the free end of the platform, is below a set of wheels carried on the chassis of the rail car. The center portion of the platform is at a height above that of these rollers. The rollers are arranged to extend laterally of the rail car and to overlie the beams. As the rail car pulls into the station, the rollers will engage the upwardly sloping part of the beams to thereby raise the chassis in relation to its wheels by virtue of extending the suspension as the car continues in its direction of movement. The chassis is, thus, brought into a suitable level to enable the loading floor to freely rotate to overlie the station platform and, thereby, enable the loading and/or unloading operations to take place.

Title: Method and apparatus for determining resonant frequency of a turbine blade made of a meterial not responsive to a magnetic field
Inventor: MOORE DONALD WAYNE
IPC: G01N29/12
Filed: 1988-09-22
Abstract: A method and apparatus for resonant frequency testing of free standing turbine blades made of a material, such as titanium, that is not responsive to a magnetic field is disclosed. A lightweight shim 12 made of a magnetically responsive material such as steel, weighing on the order of 0.5 grams, is attached to the convex side of the blade 10. The shim 12 is excited by an oscillating magnetic field and moves the blade 10 accordingly. The maximum amplitude of blade 10 movement is recorded and used to determine the resonant frequency as the excitation frequency of the magnetic field is swept through a frequency window range. The low weight of the shim 12 does not materially change the resonant frequencies of the blade 10.

Title: Rigid sheath for a spark plug cable and its associated boot
Inventor: STUDERVAN RONALD P
IPC: F02P13/00
Filed: 1988-11-11
Abstract: A rigid sheath for a spark plug cable and its associated boot is provided by combining two lockable components, each of which is mutually symmetrical along the axial direction. The rigid sheath includes a lower portion structured to interlock with the boot and an upper portion structured to route a portion of the spark plug cable through a bend of substantially 90 DEG so that it is kept out of the way of structures within the engine compartment. Because the rigid sheath combines columnar strength, a handle and an interlocking relationship with the boot, easy installation and removal of the spark plug cable and its associated boot in relation to a spark plug is made possible, even where the spark plug is surrounded by nearby structures such as a deep well of the engine.
Patent ES-2016135-A6 (ES)
Title: Flowmeter controller for an air inleakage monitoring system
Inventor: TWERDOCHLIB MICHAEL
IPC: F16K7/10
Filed: 1989-02-24
Abstract: A method and apparatus for controlling the operation of a normally open bypass valve in a steam turbine air inleakage exhaust vent pipe. The valve is used to bypass a flowmeter connected in a bypass pipe parallel with the valve. The flowmeter provides signals indicative of bypassed flow. The method and apparatus compares the signals from the flowmeter to a reference signal corresponding to a first predetermined flow rate and generates a valve closure signal if the flow through the flowmeter is less than the predetermined flow rate. If the valve is closed, the signals from the flowmeter are used to display the actual air inleakage exhaust rate. If the flow exceeds a second predetermined value, a signal is generated to open the valve for bypassing the exhaust through the valve around the flowmeter. During the second mode of operation, the flowmeter indicates only approximate inleakage exhaust flow rate. If the flow drops below the first predetermined value, the valve is again closed and the flow rate is measured by the flowmeter.
