Title: Clutch release mechanism
Inventor: BAER KURT R
IPC: F16D25/08
Filed: 1991-12-18
Abstract: CLUTCH RELEASE MECHANISM           Abstract An improved release mechanism for a hydraulically operated clutch.  A tubular cylinder is formed between stationary inner and outer housings.  A tubular piston has an inner end extending into the cylinder and has an outer end mounting a thrust bearing.  Rotating clutch release levers engage the thrust bearing.  One or more radial holes extend through the piston adjacent the inner end.  Pins positioned in the holes extend into inner housing grooves which extend parallel to an axis of the release mechanism.  The pins and grooves prevent rotation of the piston relative to the stationary housings, while allowing axial piston movement.  A retainer ring is positioned in an annular groove in the exterior of the piston.  The retainer ring both retains the pins in the piston holes and retains the piston in the cylinder.

Title: Dispenser for insect semiochemicals, method for the preparation thereof and method for the control of insects
Inventor: DERKS PETRUS S M
IPC: A01N25/10
Filed: 1990-07-20
Abstract: The invention provides a dispensing composition for the controlled release of semiochemicals, such as pheromones, wherein the semiochemical is enclosed in a network of a crosslinked polymer which is substantially free of radical initiator residues. The dispensing composition can be prepared by mixing a prepolymer with the semiochemical and optional additives and crosslinking the mixture by means of gamma radiation or electron beam treatment, or by UV  radiation or heat in the presence of a radical initiator, the residues of which are subsequently extracted. The prepolymer is preferably an acrylate or methacrylate terminated prepolymer. The rate of release of the semiochemical can be varied by modifying the network density, the type of prepolymers, the degree of loading and the shape of the dispenser. Vulnerable semiochemicals can be stabilized by adding stabilizers, such as UV absorbers and antioxidants. The predetermined release rate can be sustained for several months. The composition can be shaped or applied as a coating.

Abstract: REPEAT SEQUENCE CHROMOSOME SPECIFIC                     NUCLEIC ACID PROBES                   ABSTRACT OF THE DISCLOSURE          A primer directed DNA amplification method to isolate efficiently chromosome-specific repeated DNA wherein degenerate oligonucleotide primers are used is disclosed.          The probes produced are a heterogeneous mixture that can be used with blocking DNA as a chromosome-specific staining reagent, and/or the elements of the mixture can be screened for high specificity, size and/or high degree of repetition among other parameters.  The degenerate primers are sets of primers that vary in sequence but are substantially complementary to highly repeated nucleic acid sequences, preferably clustered within the template DNA, for example, alpha satellite repeat sequences.  The template DNA is preferably chromosome-specific.  The probes of this invention can be used to determine the number of chromosomes of a specific type in metaphase spreads, in germ line and/or somatic cell interphase nuclei, micronuclei and/or in tissue sections.  Also provided is a method to select arbitrarily repeat sequence probes that can be screened for chromosome-specificity, and probes produced in a PCR method using nondegenerate primers.
Patent CA-2065979-A1 (CA)
Inventor: THOMPSON STEPHEN P
IPC: G06F3/14
Filed: 1992-04-14
Abstract: A full screen of video data is stored in a video memory.  A small block of video data to be imminently displayed on a raster scan display device is copied, two double-words (32 bits) at a time,  from the video memory to a 6 by 32-bit first in, first out buffer (FIFO).  A fill detection circuit determines when the fill level of the FIFO is at or above certain predetermined  levels;  specifically,  3,  5  and  6 double-words.   The current operating mode is stored in a programmable mode register wherein each mode corresponds to a  unique  screen  resolution.    For  example,   one  mode corresponds to a 1024 by 768 pixel resolution having 256 colors per pixel, while another mode corresponds to a 320 by 200 pixel resolution having 4 colors per pixel.  A minimum fill  level  is  selected  by  a  level  selection  circuit depending on the current operating mode.  Since the FIFO is emptied quickly in a high resolution mode, a higher minimum fill level is selected for high resolution modes than for low resolution modes.  Processor access circuitry permits a central processor to write new video data to the video memory.   The  processor  access  circuitry,  however,   is disabled  whenever  the  current  fill  level  is  below  the minimum  fill  level  set by  the  level  selection circuit. Thus, central processor access to the video memory is only permitted when there is a minimum level of data in the FIFO, and that minimum level of data is selected according to the current operating mode.

Inventor: BROWN PAUL J
IPC: G06F13/00
Filed: 1992-05-15
Abstract: A method for acquiring the node identifier of a node in a data processing input/output (I/O) system having a plurality of nodes. This procedure is part of the initialization of each node in the I/O system and may be used to establish the configuration of the I/O system such that if a connection breaks or a fault occurs between nodes, the configuration can be confirmed after the break or fault is corrected. This prevents data from being sent to the wrong device if lines were connected in a different configuration during the correction of a fault. The node identifier is a worldwide-unique identifier such that only one node is identified by a node identifier. The node identifier contains a validity code that specifies if the node identifier is valid. Also disclosed is a retry procedure for retrying the acquisition of a node identifier if the acquired node identifier is not valid, and a deferral procedure which defers the retry procedure if a link is not available. <IMAGE>

Patent CA-2096832-A1 (CA)
Inventor: TAYLOE DANIEL R
IPC: H04B1/16
Filed: 1991-11-25
Abstract: A fixed base-site (115) periodically pages subscribers (120) in a paging area (100). To prolong the battery life of the sub-scribers (120), paging groups (520) are not sent to subscribers (120) as often when the paging load is small. Since the subscribers (120) support discontinuous receive, processing of the pages will not take place as frequently and thus a battery savings is real-ized. When the fixed base-site (115) receives more pages than can be supported without exceeding a predetermined delay, the fixed base-site (115) dynamically increases the frequency that paging groups (520) are transmitted to subscribers (120). When the paging load decreases, the fixed base-site (115) dynamically decreases the frequency that paging groups (520) are transmitted to subscribers (120) and again a savings in battery life is realized.
