Title: Protecting confidential information in a database for enabling targeted advertising in a communications network
Inventor: KATZ JAMES EVERETT
IPC: G06Q30/06
Filed: 1996-06-10
Granted: 2001-05-15
Abstract: Protecting a database against the deduction of confidential values contained therein is accomplished by partitioning the database into public and private values (202), some of which public values are deemed more important than others (203). The private attribute values are electronically processed (204-226) to reduce any high correlation between the public values and the private values. Specifically the processor partitions the database (204-210) into safe tuples and unsafe tuples, which unsafe tuples have high correlative public values (216-218). The processor then selectively combines the public attribute values of the tuples (220) to camouflage such tuples from deduction of their private attribute values beyond a threshold level of uncertainty (226).

Abstract: A bond for a single layer metal bond abrasive tool can be easily chemically and electrochemically stripped from the metal core of a recovered used tool to facilitate reuse of the core. Relative to conventionally bonded tools, the speedof stripping the novel bond is quick, and the stripped core has a smooth, clean surface which needs only minimal mechanical repair prior to reuse. In one aspect, the novel bond consists essentially of a ternary bond composition of copper, tin and titanium, in which the copper and tin are pre-alloyed and the pre-alloy and titanium component are incorporated in the bond composition as fine particle size powders. In another aspect, the bond is a quaternary bond composition consisting essentially of copper, tin, titanium and silver. The powder components can be used dry or mixed with a fugitive liquid binder as a paste. The novel bond can be brazed at lower temperature than copper/tin/titanium bonds prepared otherwise. The bond composition forms a good melt at braze temperature that flows smoothly, evenly over a tool preform and provides consistent quality bonding of abrasive from tool to tool.

Granted: 2004-04-13
Abstract: Pour différentes raisons, il peut être souhaitable de changer la manière dont une sonde est programmée pour réagir aux données qu'elle reçoit et qui la commandent. Actuellement, chaque fois que ceci doit être fait, il est nécessaire de soulever la sonde hors du trou de forage et de la démonter pour pouvoir sortir l'ancienne mémoire ROM et la remplacer avec une nouvelle mémoire ROM contenant le nouveau programme. Un tel système est compliqué à utiliser et peu efficace. Pour résoudre ce problème, on propose une sonde comprenant également : un moyen de traitement de signaux pour traiter un signal de détection échantillonné suivant un premier programme de traitement des signaux; une première mémoire pour enregistrer ce programme de traitement des signaux; et une seconde mémoire, mémorisant un programme d'écriture pour écrire le programme de traitement des signaux dans la première mémoire en fonction d'un ordre depuis l'appareil de traitement en surface. De cette manière, le programme de la sonde peut être remis à jour depuis la surface, simplement par téléchargement du nouveau programme, sans qu'il y ait besoin de ramener la sonde à la surface.

Abstract: A packet of data is received from a LAN and transmitted over a WAN, by retaining the native LAN frame format of the packet during transmission across the WAN. Thus, LAN data may be transmitted over a SONET  point-to-point link within a WAN network without the interim steps of creating ATM cells or other WAN transport packaging protocols. Instead, the LAN data may be transmitted directly over the SONET link as raw data, and reconstructed directly at the receiving end of the SONET link. A first buffer stores data from the LAN so that a corresponding packet size may be determined, and a second buffer stores data from the WAN to account for any speed difference between the LAN circuitry and WAN circuitry.

Title: In vitro and in vivo growth-promoting proteins and peptides for kidney epithelial cells
Inventor: TOBACK F GARY
IPC: C12N5/06
Filed: 1998-05-22
Granted: 2007-12-04
Abstract: Novel growth peptides derived from protein factors having molecular weights of about 22 and 45 kDa stimulate mitogenic activity of epithelial, but not fibroblastic cells, in particular, kidney epithelial cells, both in vitro and in vivo. A source of the factors is scrape-wounded kidney epithelial cells in culture. Synthetic peptides having sixteen amino acids or less, in particular a hexapeptide, Y/CPQGNH maintain the mitogenic activity. The peptide AQPYPQGNHEASYG (14-Ser) is effective in reversing both nephrotoxic and ischemic acute renal failure in rats. The growth-promoting characteristics of the 22 and 45 kDa proteins and the peptides are useful in treating and diagnosing patients with kidney disease. Nucleotide sequences that encode the factor are useful to develop probes to locate similar factors, to identify genetic disorders involving the factor, and to produce the factor by genetic recombinant methods. The nucleotide sequences and fragments thereof, are also useful for diagnosis and treatment of kidney disorders.

Abstract: A rotary shaft (20) is inserted to a tank (12) through a hole (22) formed in a wall of the tank (12). A casing (30) is provided outside the tank (12), and the rotary shaft (20) is supported by a bearing (76) arranged in the casing (30). The casing (30) is watertightly connected to the wall including the hole (22) through a flexible joint (34). Seal members (50, 52, 60) are arranged in the casing (30) to seal the clearance (22a) between the rotary shaft (20) and the casing (30). A sleeve (64) is fitted on the rotary shaft (20) so that the sleeve (64) is watertightly in contact with at least one of the seal members (50, 52, 60), and the sleeve (64) can be moved along the rotary shaft (20) to change the seal member (50, 52, 60) in contact with the sleeve (64). The bearing (76) and the seal member (50, 52, 60) are not affected by the deformation of the tank (12) since the flexible joint (34) connects the tank (12) and the casing (30), and the rotary shaft (20) can rotate smoothly while securing high sealing quality. The alignment of the axes of the bearing (76) and the hole (22) in the tank (12) can be easy since the bearing (76) is provided outside of the tank (12), and thus assembly and maintenance of the structure are easy. The tank (12) can have relatively low strength since the tank (12) has not to support the rotary shaft (20) with the bearing (76); thus the structure can be compact and the cost can be reduced.

Abstract: The vibrating drive is especially suited for a mold for producing concrete moldings and consists of at least one piezoelectric vibration exciter which is located stationary on the mold. The vibration exciter is formed by a housing in which an unbalance mass is movably supported and is drive-connected to a piezoelement which is likewise located with a vibration capacity in the housing. By applying an AC voltage to the vibration exciter, a deformation motion is formed which is converted into an oscillating motion of the unbalance mass and which thus produces vibrations of the mold. By using a different number of vibration exciters which can be made relative small and compact in dimensions, and by their attachment to different points on the mold with a horizontal and/or vertical direction of vibration, the vibrating drive and thus the vibration behavior of the mold can be adapted to different operating conditions.
