Title: Assays for inhibitors of ftsh
Inventor: SUBRAMANI SURESH
IPC: C12Q1/6897
Filed: 2000-02-22
Abstract: This invention provides a bacterial system and assay for detecting and quantifying activity of bacterial growth regulator, FtsH. The bacteria inclu de three expression cassettes. An FtsH expression cassette comprises a first promoter operatively linked to a nucleotide sequence encoding FtsH. A transcriptional regulator expression cassette comprises a second promoter operatively linked to a nucleotide sequence encoding a transcriptional regulator which regulates the activity of a third promoter, wherein the transcriptional regulator is a substrate of FtsH. A reporter expression cassette comprises the third promoter operatively linked to a reporter gene.  The activity of FtsH can be read out as a positive expression of the reporte r gene. The invention also provides an assay for compounds that modulate the expression of FtsH. The assay involves contacting the recombinant bacterial cell with the agent, and determining whether the agent modulates the expression of the reporter gene.

Patent CA-2371268-A1 (CA)
Inventor: OLSCHEFSKI ROBERT D
IPC: G01B21/18
Filed: 2000-04-21
Abstract: A system for verifying the quality of a pressing operation of a press-fit part onto a receiving portion of a receiving assembly. The system is applicable to the installation of a bearing cup onto a shaft, or a valve seat into a cylinder head. A probe measures a predetermined dimension of the press-fit part to establish a first measurement value. In the case of a valve seat installed a receiving pocket of a cylinder head, a measuring probe is inserted into the receiving pocket of the cylinder head to measure its depth. The depth is recorded as a second measurement value. The valve seat is then pressed into the pocket, and the residual depth is measured to determine the distance between the outermost surface of the pressed in valve seat and the outer surface of the receiving pocket. A computation compares the depth of the pocket against the thickness of the valve seat to determine a difference which is then compared to the residual depth.

The transmission points (12) lie substantially along the straight line, and each transmission point (12) is separated from its neighboring point(s) (12) by a first fixed distance. The spatial coordinates  of at least two transmission points (12) are determined by receiving signals  transmitted from these transmission points (12) in the set of receivers (18) , and processing the received signals. A at least one characteristic point (24 ) being co-linear with the transmission points (12), and separated from at lea st one transmission point (12) by a second fixed distance, is determined. The spatial coordinates of this characteristic point (24) are calculated using t he spatial coordinates of the two transmission points (12), and the second fixe d distance, and the spatial representation of the surface (23) is determined and/or calculated. Whenever the straight line and the surface (23) intersect , the spatial coordinates of the intersect point are calculated. A first graphical representation, indicating coincidence between the intersect point  and the characteristic point (24), and a second and different graphical representation, indicating lack of coincidence, are displayed on a graphical  representation of the surface (23).

Abstract: L'invention concerne un capteur d'angle pour dispositif de réhabilitation orthopédique, comprenant un aimant et un capteur à effet de Hall. L'aimant est fixé à un premier élément du dispositif de réhabilitation orthopédique, et le capteur à effet de Hall est fixé à un second élément dudit dispositif. Le capteur à effet de Hall détecte la présence d'un flux magnétique créé par l'aimant, et produit un signal de tension de sortie qui se transforme en une fonction du flux magnétique détecté par ledit capteur à effet de Hall. Lorsque le premier élément tourne par rapport au second, l'aimant tourne par rapport au capteur à effet de Hall, ce qui entraîne une modification du flux magnétique détecté par le capteur à effet de Hall. Cette modification du flux magnétique entraîne une modification d'amplitude du signal de tension de sortie généré par le capteur à effet de Hall, qui est convertie en équivalent angulaire.

Title: Temperature compensator for a pressure splitter control chamber
Inventor: HOLTZMAN BARRY L
IPC: F02M7/11
Filed: 2002-09-16
Abstract: A temperature compensator for a pressure splitter control chamber has two members which have different thermal expansion rates, and the dimensional changes in these two members caused by temperature change affect the pressure inside the control chamber. The compensator is normally designed so that the control chamber pressure is essentially constant with temperature change, but can be designed to increase or decrease the effect of temperature change on the pressure. This temperature compensator is especially useful in a control chamber used with a pressure splitter which is used as a carburetor compensator. The resulting temperature compensated control chamber allows the pressure splitter to easily be set for use with carburetors jetted for different base altitudes.
