Patent CA-1336379-C (CA)
Title: Pre-slit injection site and tapered cannula
Inventor: JEPSON STEVEN C
IPC: A61J1/00
Filed: 1994-03-21
Granted: 1995-07-25
Abstract: A pre-slit injection site includes a housing with a flow path therethrough.  A first end of the housing carries a pre-slit septum.  One form of a blunt cannula, usable with the injection site, carries a locking member.  When the pre-slit injection site slidably receives the blunt cannula, the locking member latches to the injection site and creates a mechanically coupled unit.  Another form of the cannula includes a tube having a tapered distal end region and having elongate discharge slots for reducing contact surface area and for directing the flow laterally out of the cannula.  The cannula may also include a rounded lead post, an annular barb, and axially oriented grooves.

Abstract: A method for production of polycarbonate-polyether-blockcopolymers is provided. One or more solutions comprising bisphenol A and polyalkyleneglycol and a phosgene solution are added to a cooled initial reaction medium in a cooled reaction chamber in such a way that the phosgene contacts substantially the reaction partners from the one or more cooled solutions after they have spread in the reaction medium. Preferably the phosgene solution and the one or more solutions are added through tubes ending above the liquid level of the reaction medium such that the solutions added contact only within the stirred reaction mixture the reaction partner. The phosgene is employed in an excess of less than about 10 weight percent of the stochiometrically required weight amount relative to bisphenol A and polyalkyleneglycol. The polymer is useful in the production of membranes for dialysis, ultrafiltration and reverse osmosis.

Abstract: The subject of this invention is the design of a mechanism for the feed of the paper in a flat plotter for drawing, which is cheap and has a high level of operational reliability. The mechanism consists of a reduction motor which rolls up the paper after it has passed through the drawing zone; in the drawing head an optical line reader is fitted which is designed to read a trace made by the drawing tool once the drawing has been completed in one window; when this trace is detected, a stop command is delivered to the rolling-reducer motor. Once the paper feed has stopped, in order to exactly join and continue the drawing of the following window in the correct form, the drawing tool carries out a search for the trace at very low speed. When the line has been detected in this process, the plotter continues with the drawing operation in the correct place.

Inventor: PFEIL DIRSKO VON
IPC: H04B3/23
Filed: 1988-07-28
Abstract: The step width with which a transversal filter (21) in the echo canceller (10) is set is also dependent on the size of the error signal (F) at the transmission path output (13). As a result, when a large signal (F) occurs, the echo canceller (10) quickly compensates with a large step width for the echo which causes the greatest interference and subsequently, when a smaller error signal (F) occurs, effectively cancels the residual echo with a smaller step width. In the case of duplex operation which cannot be reliably identified, a large signal is simulated. The aim is to prevent this effect. An echo measuring device (26) identifies duplex operation with relative reliability and sends a step width setting signal (S) to the transversal filter (21). A frame adaptation memory (28) detects a phase shift or slip and then resets the echo measuring device (26) with a reset signal (R). The echo canceller is used in international gateway exchanges. <IMAGE>

Abstract: The invention is concerned with a method and an apparatus for impregnating fibre bundles by means of molten or liquid resin in manufacturing a fibre-reinforced material, which material comprises one or more fibre bundles in which each fibre is surrounded by matrix resin, by impregnating a continuous web of one or more fibre bundles with a molten or liquid resin and solidifying said resin by cooling or chemical reaction.  Before said impregnation the molten or liquid resin material is made subject to shear forces by forcing it to flow through a channel ending at an impregnation point, the channel containing at least one section having decreasing cross-section and/or the channel having a cross-section sufficiently narrow to cause shear forces to impinge on the liquid resin, thus decreasing viscosity therein.

Abstract: An overload relay includes a base (22) with electrical contacts (162, 164) thereon. A lever (116) including a contact actuator (140) is in proximity to the contacts (162, 164) and a pivot (122) mounts the lever (116) on the base (22) for pivotal movement between first and second positions. A releasable latch (106) normally holds the lever (116) in a particular one of the positions and a spring (144) is interposed between the base (22) and the lever (116) at a location spaced from the pivot (122) to bias the lever (116) toward the other of the positions by applying a bias thereto in a generally predetermined direction. The direction and location are such that when the lever (116) is in a latched position, the bias will provide a relatively small force tending to move the lever (116) toward the unlatched position and further is such that as the lever (116) moves towards the first position, the bias produces an increasing force tending to move the lever (116) towards the unlatched position.

Abstract: It has been found that surface reactions with basic materials such as amines found in the processing environment during lithographic processing contribute to a loss of linewidth control for resists such as chemically amplified resists, This loss in linewidth  results from the reaction of the acid generated by exposing radiation with, for example, the amine resulting in a lack of chemical reaction where such reaction is desired. The problem is solved in one embodimentby employing an acid containing barrier layer on the resist.
