Patent CA-2152694-A1 (CA)
Inventor: ABRAMOVICI MIRON
IPC: G06F11/22
Filed: 1995-06-27
Abstract: A method of identifying untestable faults in a logic circuit.  A lead in the circuit is selected and the circuit is analyzed to determine which faults would be untestable if the selected circuit lead were unable to assume a logic 0 and which faults would be untestable if the selected circuit lead were unable to assume a logic 1.  Faults that would be untestable in both (hypothetical) cases are identified as untestable faults.  Faults which would be untestable if the selected lead were unable to assume a given value may be determined based on an implication procedure.  The implication procedure comprises the forward propagation of uncontrollability indicators and the backward propagation of unobservability indicators.  An uncontrollability indicator for the given value is assigned to the selected circuit lead and propagated forward through the circuit according to a set of well-defined propagation rules.  In addition, unobservability indicators are generated in the circuit based on the propagation of uncontrollability indicators.  These unobservabilityindicators are then propagated backward through the circuit.  The (hypothetically) untestable faults are then determined based on the resultant indicators and their corresponding circuit leads.  Untestable faults may be identified in a sequential circuit by generating an equivalent combinational iterative array circuit model for a fixed number of time frames. Faults that would be untestable in both (hypothetical) cases and which are located in the last (i.e., latest-in-time) time frame are identified as untestable faults.

Patent CA-2156129-A1 (CA)
Inventor: MANKE KEVIN RAY
IPC: E21B49/08
Filed: 1995-08-15
Abstract: An annulus pressure responsive tool of the type which contains lateral circulation ports and a ball valve, each operable between open and closed positions to configure the tool into different modes of operation. These modes include a well test position in which the ball valve is open and the circulation ports are closed, a blank position in which the ball valve and circulation ports are both closed, and a circulating  position in which the ball valve is closed and the circulating  ports are open. Through manipulation of annulus pressure, the tool mode can be changed during the annulus pressure release to move out of the well test position and into the blank and circulating positions. An operating mandrel assembly is described which is slidably disposed within the exterior housing of the tool and whose movement dictates the positions of both the circulation ports and the ball valve. The operating mandrel is moveable by means of an annulus pressure conducting  channel which is capable of receiving, storing and releasing annulus pressure increases. A ratchet assembly associates the operating mandrel assembly and housing and functions as an overrideable position controller to dictate response of the operating mandrel assembly to annulus pressure changes. The ratchet assembly contains a pair of ratchet balls which travel in ratchet slots on a ratchet slot sleeve. The ratchet slots feature a well test travel path within which the ratchet balls are maintained during normal operation of the tool in its well test position. The ratchet balls may be redirected into a secondary ratchet path and moved to ratchet ball positions which permit the operating mandrel assembly to be moved to positions corresponding to blank and circulating  modes for the tool. A fluid metering assembly is featured which includes a flow path towards the fluid spring during annulus pressurization permits relatively unrestricted fluid flow. A flow path is provided away from the fluid spring during a release of annulus pressure provides metered flow to provide an operator sufficient time to generate an annulus pressure increase to move the ratchet balls out of the well test travel path and into the secondary path. A hydraulic bypass assembly selectively reduces the time required for portions of the metered transmission of stored fluid pressure away from the fluid spring. It includes a bypass mandrel and fluid communication  bypass grooves which increase the flow of fluid during portions of the pressure release.

Title: Organic fertilizer and method of manufacturing it
Inventor: FISCHER KLAUS
IPC: C05F7/02
Filed: 1994-03-18
Abstract: The invention concerns a high-grade long-duration organic fertilizer and a method of manufacturing it by the oxidative ammonolysis of industrial lignin. The fertilizer contains nitrogen in the form of ammonium compounds normally hydrolysable amides and more strongly bound organic nitrogen, the proportion of more strongly bound organic nitrogen being 55 to 85 %, preferably 65 to 80 %, relative to the total nitrogen content of the fertilizer. The manufacturing process uses industrial lignin precipitated under alkaline conditions from alkaline waste liquors, extracts or solutions. Preliminary tests have confirmed that this process gives a natural-like high-grade, long-duration fertilizer similar to humus in character and with surprisingly good environmental compatibility.

Title: Genomic dna fragments containing regulatory and coding sequences for the .beta.2-subunit of the neuronal nicotinic acetylcholine receptor and transgenic animals made using these fragments or mutated fragments
Inventor: CHANGEUX JEAN-PIERRE
IPC: C07H21/04
Filed: 1995-12-13
Abstract: Several genes encoding subunits of the neuronal nicotinic acetylcholine receptors have been cloned and regulatory elements involved in the transcription of the .alpha.:2 and .alpha.:7-subunit genes have been described.  Yet, the detailed mechanisms governing the neuron-specific transcription and the spatio-temporal expression pattern these genes remain largely uninvestigated.  The .beta.2-subunit is the most widely expressed neuronal nicotinic receptors subunit in the nervous system.  We have studied the structural and regulatory properties of the 5' sequence of this gene. A fragment of 1163 bp of upstream sequence is sufficient to drive the cell-specific transcription of a reporter gene in both transient transfection assays and in transgenic mice.  Deletion analysis and site-directed mutagenesis of this promoter reveal two negative and one positive element.  The positively acting sequence includes one functional E-box.  One of the repressor elements is located in the transcribed region and is the NRSE/RE1 sequence already described in promoters of neuronal genes.
