Title: Identifying oil well sites
Inventor: EADINGTON PETER JOHN
IPC: E21B49/02
Filed: 1995-07-24
Abstract: Methods for determining maximum oil saturation and possible oil zone location use natural oil inclusions in rock grains of granular rock samples. A first technique involves quantitatively determining the total number of grains in the sample and, of those grains, the number that include oil within them, thereby yielding a ratio (GOI); and correlating that ratio against standard rock samples to yield the maximum oil saturation. A second technique involves determining the location of oil containing and/or oil absent zones in geological sites by (a) sampling in the geological site from a first rock portion capable of granular retention of oil and subjecting the first rock portion sample to the technique of GOI; (b) sampling in the geological site from one or more further and distinct rock portions, each capable of granular oil retention, and subjecting the or each further rock portion sample to the technique of GOI; and (c) comparing the results of GOI between the first rock portion and one or more of each further rock portion to determine whether or not the or each further rock portion is located in a different zone within the geological site from that of the first rock portion.

Title: Sterile medical injection port and cover
Inventor: MENYHAY STEVE Z
IPC: A61M39/16
Filed: 1996-02-16
Abstract: A unique external injection port cover is provided that is open at one end, closed at the other end, and includes a set of spiraling screw threads on the inside. It is designed to be screwed into place over a specially adapted external injection port having its own corresponding screw threads. The inside of the closed end of the cover includes an inwardly pointing projection. A sponge is provided inside the open end, and a shatterable plastic capsule containing a combination of antiseptic, bactericidal and virucidal agents is provided between the sponge and the projection. A flexible O-ring seal is provided on the inside of the cover near the open end. When the present invention is screwed into place over an injection port, the O-ring first creates a seal over the end of the port. As the invention is tightened down, the pressure between the projection and the breakable capsule causes the capsule to rupture thereby releasing the antiseptic agents inside to be soaked up by the sponge. When completely tightened, the antiseptically treated sponge comes into contact with the latex membrane of the port, keeping it saturated, clean and aseptic until the cover is removed. The present injection port cover requires no maintenance when not in use resulting in decreased risk of infection and longer life of the injection port itself.

Filed: 1996-05-21
Abstract: The present invention is a distributed computer system having a plurality of end user terminals and a plurality of loosely coupled server computers that share no resources with each other. A multiplicity of user application processes are distributed over the server computers. An Enq table is stored on a first one of the server computers. The Enq table includes Enq records, each representing a locked resource. When any user application process executes an Enq instruction naming a specific resource, if the Enq table does not already contain an Enq record for the specific resource an Enq record is generated and stored in the Enq table representing the specific resource as locked. The Enq record is stored in the same Enq table on the first server computer regardless of which server computer executes the Enq instruction. If the Enq table does already contain an Enq record for the specific resource, execution of the user application process that executed the Enq instruction is suspended. When any user application process executes a Deq instruction naming a specific resource, the corresponding Enq record, if any, is deleted. In addition, execution is resumed for any user application process that was suspended when it attempted to execute an Enq instruction on the same specific resource.

Title: Process for producing pillows or the like with an appropriate filling material cartridge and process for producing the filling material cartridge
Inventor: TESCH GUENTER
IPC: B68G7/06
Filed: 1995-11-13
Abstract: Process for Making a Cushion, a Quilt, or the Like, Filling Material Cartridge Suitable for Carrying Out the Process, Process for Making the Filling Material Cartridge, and Envelope Suitable for Carrying Out the Process A process is described for making a cushion, a quilt, or the like, having an essentially closed envelope with a closable filling opening, and having a filling material of individual aggregates, e.g. fiber aggregates, down, feathers, pieces of foam material.     The reversibly compressible aggregates, which are in a separate filling material cartridge that has a far lower volume than the maximum volume of the envelope and which are thus under high pressure, are introduced into the envelope through the opening along with at least a part of the filling material cartridge, whereupon the filling material cartridge is opened inside the envelope and the envelope is filled as the aggregates expand out from the filling material cartridge. This novel filling operation can be carried out by the specialty retailer or even by the end customer without additional special filling equipment.     The actual cushion or quilt manufacturer makes only particular, empty envelopes and various sizes of filling material cartridges so that their inventory is also reduced. As a result, the transport volume of the cushion or the quilt is sharply reduced.
