Abstract: "MODIFIED  POLY(2,6-DIMETHYL-P-OXYPHENYLENE),  A  PROCESS  FOR  ITS  PREPARATION AND ITS USE IN GAS MIXTURE SEPARATION MEMBRANES"                              ABSTRACT            An amorphous modified poly(2,6-dimethyl-p-oxyphenylene) (PPO) is described with a glass transition temperature (Tg) within the range of 170-220°C, of which the macromolecules contain units having trialkylsilyl groups bonded to the nucleus and/or to the methyl:             together with units having hydroxyethyl groups bonded to the nucleus and/or to the methyl:       This modified PPO is prepared by metalating PPO with a metalating agent and reacting the formed metalated PPO with a trialkylsilyl halide and with ethylene oxide in succession.    The use of the thus modified PPO for the preparation of flat, including asymmetric, membranes useful in gas mixture separation processes is described.
Patent CA-2021182-A1 (CA)
IPC: G01S19/48
Filed: 1990-07-13
Abstract: Abstract of the Disclosure A position estimation apparatus is adapted to estimate the position of a target in the steps as will be set forth below.  The target is observed four or more times by an image sensor during a lime period in which the target and movable body unit move in those directions not parallel to each other.  Acceleration is applied to an accelerator at least once at a time between the observation times.  Two-dimensional angle information of the target's azimuth and elevation angles is detected from the image information of the target acquired by the image sensor at the time of observation. A coordinate system of the movable body unit is found in accordance with the position and attitude information of the movable body unit, and the two-dimensional angle information of the target is plotted on the coordinate system.  Simultaneous equations are prepared by sequen-tially substituting the two-dimensional angle informa-tion of the target obtained through the observation into an equation of motion representing a regular motion of the target initially entered on a position estimation apparatus.  Parameters in the equation of motion is found from the simultaneous equations.  The position of the target at a given time is estimated by substituting the parameters into the equation of motion and the given time into the latter equation.

Patent CA-2023003-A1 (CA)
IPC: B02C4/30
Filed: 1990-08-09
Abstract: Abstract The invention relates to a machine for compacting and/or crushing bulk material, in which two rollers which can be pressed together at high pressure each consist of a main roller body and a roller shell which is releasable conn-ected to the main roller body and is composed of individual segments.  Each of the individual segments has one single lug projecting in the circumferential direction on the front long side in the direction of rotation of the roller and one single complementary recess on the rear long side in the direction of rotation of the roller.  The generatrices of the outer surfaces of the segments point in the circumferential direction and run radially with respect to the roller axis.  This results in a simple construction of the segments and a high degree of security against tilting.

Filed: 1990-09-13
Abstract: ABSTRACT OF THE DISCLOSURE       A cell transfer apparatus and method using a varia-ble rate codec wherein a sequence number of each cell is determined by adding a weight corresponding to an encoding time of information.  In a transmitting side, each of encod-ed pieces of information is cellulated  to a predetermined length cell for each information having  a length of integer times a predetermined unit length of information.   A se-quence number of a next cell is determined by adding as a weight the number of pieces of information having a unit length included in the last cell to a sequence number of a last cell, and is sent as being added to each cell.   In a receiving side,  reproduction timing numbers comprising serial numbers are sequentially generated at timings syn-chronous with the unit length of the pieces of information and compared with the sequence number added to each cell.          When the both coincide, the information of that cell is decoded.

Inventor: INGRAM GARY L
IPC: D05C15/24
Filed: 1990-10-26
Abstract: Apparatus for producing tufted textile goods employs a plurality of hollow needles which serve as backing openers, the backing openers being carried on a widthwise extending member which is reciprocated in a vertical direction to cause the backing openers to penetrate a backing.  Yarn is transported pneumatically through the backing openers and implanted into the backing as yarn tufts, the backing being shifted in the transverse direction by an amount corresponding to the spacing between adjacent backing openers in order to implant a transverse row of tufts.  A knife blade is associated with each backing opener and positioned on the opposite side of the backing so as to engage the flat angled surface of the backing opener which forms its pointed tip.  The angled surface is formed with an upwardly and inwardly extending slot which serves to capture and center yarn exiting the opening in the angle surface, and which provides a sharp edge which cooperates with the blade for cutting the yarn.

Patent CA-2036632-A1 (CA)
Inventor: MULLER PETER H
IPC: E05B63/24
Filed: 1991-02-19
Abstract: In a first embodiment, the invention has a casing set in the frame of a door in confronting relationship to the latchbolt-confining housing of the door.  A bolt, translatable in the casing, is extended, by a solenoid, and enters the housing to prevent opening of the door.  A latchbolt position sensor, in the form of a dual-ended limb, monitors the position of the latchbolt.  Upon withdrawal of the latchbolt, from latching closure of the door, the limb actuates a switch to operate a time delay circuit component.          When the specified time delay set by the component has run its course, it cuts power to the solenoid.          Compression springs withdraw the bolt from the latchbolt-confining housing, to permit the door to open.

Abstract: In a cordless key telephone system for servicing separate service zones (31, 32), a cordless station (5) establishes a two-way radio channel with an access unit (4) of the service zone in which it is located, and constantly monitors the field intensity of the established channel and transmits a zone switching signal when the field intensity is below a specified level as an indication that the cordless station is leaving a first zone (31) and entering a second zone (32). A main controller (2) establishes a switched connection between exchange lines (6) and the access units (4). In response to the zone switching signal from a given cordless station via the access unit of the first zone, the main controller holds an exchange line (6i) that is connected to the access unit (4j) of the first zone through a first switched connection, and establishes a second switched connection between the exchange line (6i) and the access unit (4j) of the second zone, instead of the first switched connection.

Abstract: A plasma arc torch mounts an electrode and a nozzle, with a mutual spacing, symmetrically about a common longitudinal axis at one end of the torch adjacent a workpiece.  The inner surface of the nozzle has an annular, inwardly-directed projection, located opposite the electrode and at a point of closest spacing between the electrode and the nozzle.  The projection, or "angle kink", is characterized by a minimum radius of curvature as compared to the radii of curvature of adjacent portions of the nozzle opposite said electrode.  The inner surface is adjacent a central exit passage of the nozzle and the angle kink is spaced from the intersection of the exit port and the inner nozzle.  In the preferred form the interior nozzle surface is formed by two conical surfaces each having different slopes with respect to the longitudinal axis so as to form the circumferentially extending angle kink at their plane of intersection.
