Title: I.v.s. pump
Inventor: LOVAS STEVE
IPC: F04B47/00
Filed: 1991-04-30
Abstract: ABSTRACT          A  hydraulically  actuated  pump  that  can  be  remotely operated manually or by other forms of  power to  pump water  or fluid from depths or  locations remote  from the  primary drive  system.  The stroke length can be varied according to the well yield and piston diameters can be changed to attain variable forces. The pump  consists of  a flow  and return line, as such the forces are relatively equal.   By  displacing  this  fluid,  either  by a hydraulic motor or a reciprocating cylinder, or the combination of both, the two opposed pistons through one way  valves, create flow displacement in  one direction only.  The pump also compresses air in a chamber which helps to  lower the  stress reversals  and also aids in  efficiency.   The flexible lines make installation easier and  allow   the  well   head  to   be  sealed   to  prevent  well contamination.

Title: Metastasis-associated collagenolytic metalloproteinases
Inventor: NAKAJIMA MOTOWO
IPC: G01N33/577
Filed: 1990-01-29
Abstract: Disclosed are methods and compositions for testing for various types of human cancers, including in particular metastatic mammary carcinoma, colon carcinoma astrocytoma, renal cell carcinoma, and teratocarcinoma malignant melanoma. The diagnostic method of the invention involves the detection of a gelatinolytic and type IV  collagenolytic metalloproteinase having molecular weight of approximately 88 to 92 kilodaltons in size. This high molecular weight type IV collagenolytic enzyme is found to be associated with the cancerous state, but this has not been found in any noncancerous cells tested and further not found in the serum of non tumor bearing animals. The enzyme is associated both with rat and human tumors, the enzyme in each case being quite similar. Methods are disclosed for isolating the 88/92 kd enzyme, the isolated enzyme being useful as a control enzyme and diagnostic assays.  Furthermore, the isolated enzyme will be useful in the preparation of antibodies, including monoclonal antibodies, having specificity for the metastasis-associated enzyme. Techniques are also disclosed for isolation and partial purification of the enzyme from both rat and human sources. Furthermore, methods are disclosed for conducting both enzymatic and immunologic based tests for the diagnosis of metastatic and recurrent disease.

IPC: G06F3/06
Filed: 1991-11-26
Abstract: A method for on-line restoration of redundancy information in a redundant array storage system. The invention provides alternative methods of restoring valid data to a storage unit after a Write failure caused by a temporary storage unit fault, in the first preferred method, a valid redundancy block is generated for the corresponding data blocks on all storage units. Resubmitting the interrupted Write operation causes the old (and potentially corrupted) data block to be "subtracted" out of the re-computed redundancy block. The uncorruted new data block is written over the old data block, and is "added" into the re-computed redundancy block to create a new, corrected redundancy block. The new, corrected redundancy block is written to the appropriate storage unit, in the second preferred method, a new redundancy block is generated from all valid data blocks and the new data block. The new redundancy block and the new data block are then written to the appropriate storage units. In both cases, the entire method is done on-line, with insignificant interruption of normal operation of the redundant array system, and without requiring added processing during normal operation.

Title: Electronic controls for electric motors, laundry machines including such controls and motors and/or methods of operating said controls
Inventor: ENSOR DAVID J
IPC: D06F34/10
Filed: 1991-12-18
Abstract: A method of cyclically accelerating an electric motor for example for use during an agitation cycle in a laundry machine. A desired speed, direction of rotation and acceleration time is set and power is applied to the motor in a series of incremental steps, each successive step corresponding to an increase in the level of power applied during the previous step. The steps are initially estimated to be sufficient to enable sufficient energy to be supplied to the motor for it to reach the desired speed in the acceleration time. The speed of the motor is monitored and the steps of accelerating the motor are repeated with the series of incremental steps adjusted to adjust the supply of energy to the motor dependant on the speed reached in the acceleration time of the previous cycle.

Abstract: A machine and method for forming an inside corner portion in a one-piece article material where the inside corner portion is produced by the meeting at a corner of first and second adjacent profiles defined by grooves or members. The inside corner portion at the corner is formed by machining the article material to form portions of the profiles not including the entirity of the inside corner portion, and then shearing the article material in the corner to form the inside corner portion. The machine has first and second cutter assemblies each having a shear cutter. Each shear cutter is mounted for movement along a path between retracted and extended positions such that the path of movement of the cutter of the first assembly meets with the path of movement of the cutter of the second assembly. The article having partial profiles formed therein is mounted with the cutter's positioned and seated with the profiles and such that the profiles are aligned along the paths of movement of the cutters. The cutters are driven along their respective paths while seated with their respective profiles between the retracted and extended positions, such that driving the cutters to the extended position shears the material near the corner to form the inside corner portion.

Title: Method of geophysical exploration by analyzing shear-wave polarization directions
Inventor: WINTERSTEIN DONALD F
IPC: G01V1/42
Filed: 1992-06-05
Abstract: A method for geophysical exploration by analyzing shear-wave polarization directions relative to a fixed coordinate frame is disclosed, for either vertical seismic profile data or surface seismic reflection data. Energy in a selected time window of two off-diagonal components is determined, and the source and receiver coordinate frame is then rotated, and energy is again determined. A second rotation of the source and receiver coordinate frame is followed by a third energy determination. A simple trigonometric function equation is generated to fit the determined energy values, and a minimum energy value is determined. The coordinate frame is then rotated by the angle that gives the minimum energy value, so that all of the signal is put on the diagonal components. <IMAGE>

Abstract: The powder-actuated fastening tool has an axially displaceable bolt guide (3) which is displaced in the opposite direction to the drive-in direction when the fastening tool is pressed against a component (10). In the process, the bolt guide (3) acts on a piston guide (2) which in turn tightens a firing bolt (9) via a tightening device (8). The firing bolt (9) serves to ignite propellant charges. At the side, the bolt guide (3) has a feed slot (3a) which is connected to a magazine (1a) arranged on the housing (1) of the fastening tool. Fasteners (11) which are arranged in the magazine (1a) and are connected to one another in a strap-like manner via guide bushes (12) are thereby fed to the bolt guide (3), the displacement of the bolt guide (3) resulting in only a single fastener (11) coming into the effective area of a driving piston (4) through the feed slot (3a) graduated in width.
