Title: Plural vibrator single step inversion separation method
Inventor: ALLEN KENNETH PAUL
IPC: G01V1/37
Filed: 1996-10-03
Abstract: A method for generating, recording and pre-processing high fidelity vibratory seismic data in a system that uses a plurality of vibratory sources (18, 20, 22 and 24) includes the steps of measuring the motion of each of the vibrators (18, 20, 22 and 24), determining a ratio by dividing the vibratory seismic data by the measured motion of the vibrator to remove the unknown applied force leaving the earth reflectivity times a time derivative divided by a minimum phase function, minimum phase band pass filtering (54) the resulting ratio and performing minimum phase deconvolution (56) to remove the time derivative divided by the transfer function of minimum phase. The method may also include the steps of shot ensemble deconvolution (66), receiver ensemble deconvolution (72), statics correction (88), F-K filtering (70) for noise, zero phase spiking deconvolution (74) and model dephasing (76). The vibrator motion is measured to provide a signal that is used to process the data. The data is divided by the relative of the actual transmitted signal in frequency domain.

Inventor: ARMSTRONG WILLIAM R
IPC: B65D81/05
Filed: 1996-11-08
Abstract: There is provided an inflatable cushion (10) inflated through a single inflation valve (23). A pair of inflated panels (11) held in place by at least one tie strap (19) connecting the panels rest beneath each end of the bottom of an article to be protected. The cushion has a pair of inflatable end chambers (14) interconnected to the bottom panels and a pair of inflatable side chambers (18) interconnected to the end chambers, which when inflated protect the ends and sides of the article. This is facilitated by internal openings which allow the inflated panels to easily bend underneath the ends of the article and around the corners. There are recesses (15) at each corner which extend from each corner of one internal opening toward a peripheral edge of the cushion to provide a wedge-like portion of the side chambers. In one of the embodiments, an additional pair of internal openings facilitates a pair of top inflatable chambers (20) interconnected to the end chambers to rest on the top of the article. In another embodiment of the present invention, the chamber protecting the upper portion of the article includes a single inflatable chamber which folds across the top of the article. The top chamber has an internal opening (122) in the middle thereof formed by a weld.  Extending inwardly from the weld are portions of each thermoplastic sheet which remain after the cushion has been cut and adapted to hold a thin article.

Abstract: The invention concerns a process for preparing organically modified aerogels, in which: a) a silicic acid sol having a pH of  4.0 is prepared from an aqueous sodium silicate solution using at least one organic and/or inorganic acid; b) the resultant silicic acid sol is polycondensed to form an SiO2 gel by the addition of a base; c) the gel obtained in step b) is washed with an organic solvent until the water content of the gel is  5 wt.%; d) the gel obtained in step c) is surface-silylated; and e) the surface-silylated gel obtained in step d) is dried. The process is characterized in that the at least one acid forms salts with the sodium silicate cations in the silicic acid sol, which salts are difficult to dissolve. Before step b) the salts produced which are difficult to dissolve are precipitated out to the greatest extent possible and separated from the silicic acid sol.

Title: A process for manufacturing microstructure bodies
Inventor: BALLHORN RALF-ULRICH
IPC: G03F7/039
Filed: 1998-09-18
Abstract: In order to manufacture microstructures by the LIGA process, plastic layers are deeply irradiated across the image-area with X-ray radiation.  The areas of the plastic layers that have been rendered soluble or have remained soluble are removed selectively by  means of a developer.  Known plastics require a considerable outlay for irradiation.            In the process according to the present invention, photo-hardened epoxy lacquers are used; these require considerably shorter irradiation time compared to known plastics.  The microstructures can have a larger aspect ratio and can be developed without any faults even at greater structure depths.  The structure precision that is achieved is in the sub-micrometer range.            The process makes it possible to manufacture deep microstructures of very good quality, and to do so economically and with reduced irradiation outlay.

Title: Valve operating system in internal combustion engine
Inventor: GOMI TAKESHI
IPC: F01L9/20
Filed: 1998-10-28
Abstract: An actuator is connected to one of components forming a power transmitting device capable of transmitting a power provided by a valve operating cam provided on a cam shaft, so that the actuator can drive an engine valve in a lift amount which is obtained by addition of a lift amount of the engine valve based on a cam profile of the valve operating cam and a lift amount of the engine valve based on the operation of the actuator.  Thus, a portion of the lift amount of the engine valve is borne by the valve operating cam, whereby a valve-opening power borne by the actuator can be reduced, as compared with a system designed so that the engine valve is driven by only the actuator only.  The amount of electric power consumed by the actuator can be smaller.

Abstract: A method of organizing electronic documents for storage and subsequent retrieval, involves storing a summary structure describing the structure of summary records associated with each document. Each structured summary record has at least one field representative of a characteristic of the document. A predetermined number of field values identify the value of the characteristic associated with the field. Predetermined keyword criteria associated with the field values are stored.  Each document is analyzed to build a text index listing the occurrence of unique significant words in the document. The text index is compared with the keyword criteria to determine the appropriate field value for the document. For example, one characteristic field might be related to topic, which could have the field values of "financial" or "sports". The preponderance of certain keyword criteria, such as "money" or "shares" would identify the document with the financial topic.

Title: Chronic fatigue syndrome diagnosis
Inventor: SUHADOLNIK ROBERT J
IPC: G01N33/573
Filed: 1997-09-19
Abstract: Chronic fatigue syndrome is diagnosed through detection of an about 30 kDa RNase L molecule under native conditions in cellular extracts of RNase L-containing cells such as peripheral blood mononuclear cells. Proteins are fractionated according to molecular weight under nondenaturing conditions. The fractionated proteins are assayed for the presence of the about 30 kDa protein having 2-5A-dependent RNase L enzyme activity. The severity of the affliction may be determined by testing for the presence of RNase L molecules having approximate molecular weights of 30 and 80 kDa. The presence of the about 30 kDa RNase L, and the absence of the about 80 kDa RNase L molecule, correlates with severe chronic fatigue syndrome. The presence of both RNase L molecules indicates a less severe chronic fatigue syndrome affliction. Under denaturing conditions, and in the presence of protease inhibitors, chronic fatigue syndeome may be diagnosed through the detection of an about 37 kDa 2-5A-binding protein.
