Title: Farnesyl-protein transferase assay for identifying compounds that block neoplastic transformation
Inventor: BARBACID MARIANO
IPC: C12Q1/48
Filed: 1991-04-16
Abstract: Assays for farnesyl-protein transferase (FT) which can be used to identify substances that block the farnesylation of ras oncogene products are described.      Because farnesylation is required for ras oncogene activity, inhibitory compounds identified in the assays of the invention can block neoplastic transformation mediated by the ras oncogene. The assays of the invention are targeted for a step subsequent to the synthesis of farnesyl pyrophosphate (FPP), the donor of the farnesyl residue, and an intermediate in cholesterol synthesis and other important cellular pathways. Therefore, compounds which inhibit ras mediated transformation, yet do not cause major disruptions of important cell pathways that require FPP as an intermediate may be identified using the assays of the invention.

Title: Dual frequency nmr coil pair
Inventor: HASHOIAN RALPH S
IPC: G01R33/32
Filed: 1991-05-09
Abstract: ABSTRACT      A dual frequency NMR coil pair is comprised of two individual coils tuned to separate resonant frequencies.  Each coil is formed into approximately the same shape by a conductive loop which follows a serpentine path to define an inner area and a plurality of outer Lobes.  The two individual coils are positioned in close proximity overlying each other, but rotated with respect to each other such that the outer lobes of the two respective coils are interleaved, i.e. not overlaying each other.  As a result, mutual loading between the two individual coils is essentially eliminated, permitting dual frequency operation with minimal degradation of Q or signal-to-noise ratio (SNR) in either coil.

Patent CA-2060921-A1 (CA)
Title: Superconductor quench measuring system
Inventor: WOLFE WILLIAM R
IPC: G01N27/02
Filed: 1992-02-10
Abstract: ABSTRACT          A method and apparatus for detecting and locating a quench zone in a superconducting coil is provided,  A sensor is positioned adjacent to and in heat transfer communication with the superconducting coil along the entire length of the superconducting coil.  When a portion of the superconducting coil becomes normal, the adjacent portion of the sensor becomes resistive.  A series of electrical pulses are sent along the sensor. At a normal zone, the discontinuity in impedance which occurs at such a zone, causes a reflective pulse to be sent back along the sensor.  In addition, the sensor may be short-circuited at one end so that a return pulse opposite in polarity to the transmitted pulse will be reflected from that end.  Alternatively, the sensor may be open-circuited at the end and a return pulse of the same polarity as the transmitted pulse is reflected back.  Yet a further embodiment includes a resistive component of a predetermined value at the termination end.  The reflective pulses and the echo pulses are detected by an associated receiver and processor which calculate the location of the resistive zone along the sensor and the corresponding quench zone along the superconducting coil using information derived from the pulses.  A second embodiment provides two sensors which are adjacent to and in heat transfer communication with the coil which are pulsed from opposite ends.  This provides additional information about the quench zone and also provides redundancy in the system.  An associated method is also provided.

Title: Fuzzy reasoning database question answering system

IPC: G06F17/30
Filed: 1992-04-21
Abstract: ABSTRACT      A FUZZY REASONING DATABASE QUESTION ANSWERING SYSTEM            A system provides question answering based on fuzzy logic. The proposed system provides the capability to assess if a database  contains  information pertinent  to  a  subject  of interest by evaluating each comment in the database via a fuzzy evaluator which attributes a fuzzy membership value indicating its relationship to such subject.  An assessment is  provided  for  the  database  as  a  whole  regarding  its pertinence  to  the  subject  of  interest,  and  consequently comments that are considered as irrelevant to the subject may be discarded.  The system has been developed for the examination of databases and evaluated by testing against those which were  created  for  assessing whether  computer system development databases contain information pertinent to  the  functional  changes  that  would  occur  in  the development cycle. The system can be applied with minimal changes to a variety of circumstances provided that the fundamental   assumptions   for   the   development   of  the membership functions are respected for the application.

Patent CA-2074800-A1 (CA)
Inventor: JOKURA JUN
IPC: H04J3/00
Filed: 1992-07-28
Abstract: A local-oscillating-frequency synthesizer includes a pair of synthesizers, one being used for synchronizing the frequencies of the communication channels used for transmission and reception slots, and the other for synchronizing the frequencies when the electric-field level of the other station is monitored and information is read out between idle slots, i.e. slots other than the transmission and reception slots. Therefore, without using a high-speed frequency-switching synthesizer such as a direct digital synthesizer or the like, synchronization of the frequencies by switching is achieved in a short period of time, and a local-oscillating portion which is low in power consumption is obtained.

Abstract: An ion processing unit (10), including a series of M perforated electrode sheets (12), driving electronics (14, 16) and a central processing unit (18), allows formation, shaping and translation of multiple effective potential wells (42). Ions, trapped within a given effective potential well (42), can be isolated, transferred. cooled or heated, separated, and combined.  Measurement of induced image currents allows measurement and typing of ion species by their respective charge-to-mass ratios. The combination of many electrode sheets (12), each having N multiple perforations (22), creates a plurality of parallel ion processing channels (26). The ion processing unit (10) provides an N by massively parallel ion processing system, furnishing means for processing large numbers of ions in parallel in the same manner, but with different ion processes deployed at different sections of each ion processing channel (26). In addition, the space-filling parallel structure of the present invention provides an efficient means for temporary storage of large numbers of ions, including charged antimatter.
