Title: Increasing permeability of productive strata and filter layers close to well borehole, inserts generator superimposing pressure pulses on production flow
Inventor: STEINBRECHER ALEXANDER
IPC: E21B37/08
Filed: 2003-01-15
Granted: 2004-07-29
Abstract: In the production region (F) of the bore (11), fluid is pumped out continuously using an underground pump (8). The fluid is subjected to successive hydraulic energy pulses (E) acting towards the bore casing wall and filter layer (W), using a pulse generator (1), causing to-and-fro motion. The effect of each pulse is analyzed from seismic measurements. On the basis of analysis, the pulse to be delivered is determined.  Surface equipment, connected by a pressure line to the pulse generator, produces a high hydraulic pressure. The pulse generator shoots fluid out, at a given pressure for a given interval, into the fluid being pumped. A seismic sensor (10) and controller are used for measurement and control of the pulse strength and duration. Weak pressure pulses are used, and when the inner surfaces have been cleaned and the filter openings are clear, the pulses are discontinued. An extended process, in which the pulsing equipment is removed before inserting packing and the pulse generator, is described. A cleaning fluid is introduced, pulsed and finally removed, together with dissolved or suspended contaminants. The packing is removed, then a further stage of cleaning with regeneration fluid can be undertaken. An Independent claim is included for corresponding equipment used in the process.

Abstract: A method of controlling a welding operation during arc welding between a fusible electrode and a workpiece, wherein the welding operation alternates between arc periods and short-circuiting periods, includes the steps of sensing a first parameter of the welding operation, for example the arc voltage between the electrode and the workpiece, generating a first signal representative of the first parameter, sensing a second parameter of the welding operation, generating a second signal representative of the second parameter, filtering the second signal to provide a filtered signal, generating a desired value signal based upon the filtered signal and controlling the welding operation based upon the difference between the desired value signal and the first signal. According to the method of the present invention, any changes in the second signal that occur at a frequency outside a predetermined frequency range, which includes a desired short-circuiting frequency of the welding operation, are attenuated such that the desired value signal is less affected by these changes than by changes occurring at a frequency within the predetermined frequency range. An apparatus for carrying out the method includes a band-pass filter having a pass band including the desired short-circuiting frequency.

Abstract: Optically active and mesogenic 1,3-dioxolane-4-carboxylic esters are suitable for use as dopants in liquid crystal mixtures. They lead to liquid-crystalline ferroelectric phases having short response times and to electroclinic phases having large electroclinic coefficients. Their particular advantage is that they induce a helix of very large pitch, so that there is no need for any helix compensation by other dopants. Moreover, the 1,3-dioxolane-4-carboxylic esters exhibit high UV stability.

Title: Verbesserte Kalibrierkurven für Flugzeitmassenspektrometer
Inventor: BREKENFELD ANDREAS
IPC: H01J49/40
Filed: 2007-06-13
Granted: 2009-01-08
Abstract: Die Erfindung bezieht sich auf die präzise Bestimmung der Massen aus den Flugzeitwerten von Ionen in solchen Flugzeitmassenspektrometern, in denen die Beschleunigungsspannung für die Ionen nicht dauernd anliegt, sondern zu einem Zeitpunkt eingeschaltet wird, so dass sich nach dem Einschalten kurzfristig eine sich zeitlich verändernde Beschleunigung ergibt. Die Erfindung besteht darin, den Einfluss der sich zeitlich verändernden Beschleunigung auf die Kalibrierkurve, der sich einer streng mathematisch-analytischen Berechnung entzieht, formal durch die Einführung einer "reduzierten Masse" m - m<SUB>0</SUB> anstelle der Masse m zu beschreiben, wobei die Massenreduktionsgröße m<SUB>0</SUB> keine wahre Massendifferenz, sondern einen massenabhängigen Fehlbetrag der kinetischen Endenergie nach Durchlaufen der Beschleunigung beschreibt, der bei der zeitlich veränderlichen Beschleunigung zu beobachten ist. Dieser überraschend einfache Formalismus erlaubt es, die Massen der Ionen mit einer Kalibrierkurve, die nur vier bis sechs einzukalibrierende Koeffizienten enthält, über einen weiten Massenbereich mit einer Genauigkeit von etwa einem Millionstel der Masse zu berechnen.
