Patent CA-2152207-A1 (CA)
Title: Method for adaptively suppressing noise transients in summed co-sensor seismic recordings
Inventor: DRAGOSET WILLIAM H JR
IPC: G01V1/38
Filed: 1995-06-20
Abstract: Seismic data from co-located sensors of different genera are formatted into common velocity-receiver gathers and common pressure receiver gathers. A first ratio between the velocity signature amplitudes and the pressure signature amplitudes is measured within a fixed analysis window. A second ratio is measured between the pressure and velocity signatures for a weighting-zone window of limited extent. The first and second ratios are combined to form an equalization operator. The pressure and velocity signatures from within the weighting zone window are combined in the presence of the equalization operator to define a transient-free time-scale datum.

Title: Method of treatment of diseases by deletion of t cells
Inventor: MARRACK PHILIPPA
IPC: A61P43/00
Filed: 1994-04-08
Abstract: This invention includes the discovery that chronic exposure to the superantigen (SAg) staphylococcal enterotoxin (SEA) causes almost complete deletion of target T cells in vivo. Mice were either acutely or chronically exposed to varying doses of SEA, and the relative level of T cells bearing SEA-reactive V.beta. elements was followed over time in lymphocytes purified from peripheral blood, lymph nodes, mesenteric lymph nodes, and spleen. Acute exposure caused the disappearance of 50-70 % of reactive T cells. Chronic exposure caused almost complete deletion of target T cells. Deletion was evident even in animals treated with very low doses of SEA, doses too small to cause any apparent T cell proliferation. Thus, proliferation does not appear to be a prerequiste for peripheral deletion of T cells and peripheral tolerance may be achieved by chronic exposure to low levels of antigen without prior cell division.

Title: Self-diagnostic circuit for emergency lamphead
Inventor: VOSIKA DAVID A
IPC: G08B29/10
Filed: 1996-02-21
Abstract: A self-diagnostic circuit for an emergency lamphead is disclosed that is effective during standby operation of the lamphead to indicate whether the lamphead is capable of operating  in an  emergency mode.    The  self-diagnostic circuit includes a high-impedance circuit path connected in series with the lamphead and including an indicator, such as an LED, which is energized by a battery current passing through the circuit path and lamphead during the standby mode operation.   The battery current is insufficient to illuminate the lamphead, but is sufficient to energize the LED whenever proper electrical continuity exists through the lamphead.  A second high-impedance circuit path may be connected in parallel with the lamphead,  in order to energize a second LED when proper continuity does not through the lamphead.  The self-diagnostic circuit may be incorporated into each of a plurality of remote lampheads in a multiple-lamphead system, and may include a bipolar transistor  or  FET for  isolating  the  self-diagnostic circuits of the lampheads from each other.

Abstract: A mower-conditioner platform or header is suspended from the main frame of the mower-conditioner by a pair of transversely spaced lower links and a single upper link or lift arm.  A hydraulic lift cylinder is connected directly to the lift arm.  The lift arm is mounted between the main and platform frames in a manner for permitting the lift arm to undergo a given amount of side-to-side movement about its connection with the main frame in response to relative vertical movement between the opposite ends of the platform as the platform travels over uneven ground contour during cutting operation, and for limiting the side-to-side movement of the upper link to an amount considerably less than said given amount when the platform is raised to its transport position. Three different connection points are provided at the forward end of the lift arm for connection to the platform frame and by selecting different ones of these points different platform cutting angles may be obtained.  A transport lock is provided for holding the lift arm in its raised position and the mounting of the cylinder is such as to permit the latter to be stroked when the lock is engaged without any forces being transferred to the lift arm or lock.
