Inventor: DAVIES PHILIP CLAUDE
IPC: A63B69/36
Filed: 2000-11-23
Abstract: A ball return apparatus (1) including a frame (4) supporting a net or nets (2) providing a ball receiving shape which is of approximately rectangular proportions providing thereby a cavernous capturing and returning area with a lowermost net (9) or net portion shaped, held and aligned to provide a sloping of 10 degrees and tensioned floor (9) such that it will effect a return of the ball to a delivery location. The apparatus has an end panel (5), two side panels (6, 7), a roof panel (8) and a forwardly inclined lowermost panel (9) with sufficient slope so that a ball will roll out from the cavernous shape toward a player. Each of the panels (5, 6, 7, 8, 9) are held taut under relatively uniform tension by helical springs (3) connected to the frame (4).  The apparatus (1) can be used for practicing golf driving; kicking an Australian Rules football or soccer ball; pitching a baseball or softball;  throwing a cricket ball, netball or basketball; and hitting a hockey ball or tennis ball.

Title: Ethanol content rationality for a flexible fueled vehicle
Inventor: HUFF SHEAN P
IPC: G01N33/28
Filed: 2002-10-02
Abstract: A method for checking the accuracy of an oxygen sensor based determination of the alcohol content of the fuel of a flexible fueled vehicle. Following the addition of fuel to the flexible fueled vehicle two alcohol concentration possibilities are calculated.

Title: Regulation of matrix metalloproteinases by psp94 family members
IPC: C12Q1/68
Filed: 2003-09-26
Abstract: Matrix metalloproteinases (MMPs) play an important role in morphogenesis, angiogenesis, wound healing, and in certain disorders such as rheumatoid arthritis, tumor invasion and metastasis. MMPs are thought to be regulated by a variety of cytokines, growth factors, hormones and phorbol esters. This regulation occurs on three levels;  alteration of gene expression, activation of the latent zymogen and inhibition by the tissue inhibitors of metalloproteinases (TIMP). We report here a new agent that regulates the level of MMPs in patient. More particularly, members of the PSP94 family, when administered to patients having metastatic hormone resistant prostate cancer, promote a significant decrease in MMP plasma levels. The invention therefore relates to the use of a PSP94 family member for the treatment of a condition related to the activity or expression of MMPs.

Abstract: It is intended to produce an industrially useful foreign protein by making a coryneform bacterium to efficiently secret and produce the foreign protein. An expression gene construct, which has the gene sequence of a target foreign protein ligated to the downstream of a sequence encoding a signal peptide domain originating in a coryneform bacterium, is transferred into a corynefo rm bacterium variant capable of secreting and producing the foreign protein at least twice as much as in case of wild type Corynebacterium glutamicum ATCC13869 does. Then the thus transformed coryneform bacterium is cultured a nd the foreign protein released outside is collected.
