Title: Hand operated mudless drywall tape applicator
Inventor: DENKINS JEFFREY L
IPC: B65H35/00
Filed: 1996-10-22
Abstract: A tape applicator (10) applies adhesive-backed drywall tape (36) along both flat joints and corner joints. The applicator (10) has a common tape dispenser (2) to which a flat joint header (3) and a corner joint header (4) can be removably attached. The dispenser (2) includes a tape guide (60) located near a tape outlet (34) for the dispenser as well as a tape brake (69). The flat joint header (3) has a cylindrical application roller (38) with a resilient surface. The corner header includes a creaser wheel (214) that creases the tape into a corner and a guide roller (212) that guides the tape from the dispenser outlet (34) to the creaser wheel (214). A corner roller (5) having a resilient surface can be used effectively to wipe down creased tape over a corner joint. Both the flat joint (3) and corner headers (4) include tape cutters (76 and 260) to selectively cut tape (36) dispensing from the apparatus. The applicator (10) can be used with many kinds of adhesive-backed tapes (36), including reinforced drywall tape, fire tape and mesh tape.

Filed: 1998-03-30
Abstract: A fitment (24) for use on a container for dispensing liquids. The fitment (24) provides a pouring spout (26) and a drain back function (32, 44) and is secured within the container finish. The container finish has a neck (18) with a rim (22) and a shoulder (20). The fitment (24) has an outer wall (30) with upper and lower ends (36, 40) and with a frustoconical shape to ensure that a portion of the outer wall (30) frictionally engages the container finish when the fitment (24) is inserted into the container finish to prevent the fitment (24) from being inserted completely through the neck (18) of the container. An annular bead (34) extends outwardly from the outer wall (30) a spaced distance from the upper end (36) of the outer wall (30) so that when the fitment (24) is engaged in the neck (18) of the container, the bead (34) is positioned directly under the shoulder (20) of the neck (18). Multiple bands of sealing engagement are created between the fitment (24) and the container fitment to ensure a leak-free connection.

A beam member (181) receives at an input thereof at least a portion of the directional input force, and produces at first and second outputs thereof respective ones of first and second output forces. A resilient beam coupling (183,8) portion is integrally formed at the force output point of the beam member. The resilient beam (183,8) coupling portion can be formed substantially as an S-shaped member or a V-shaped member, or the resilient elements can be tiered. Alternatively, the resilient beam coupling portion is formed substantially as a pair of opposingly spaced resilient portions for forming a resilient hinge, the resilient hinge being integrally formed with the beam member.

Title: High temperature ptc device and conductive polymer composition
Inventor: ZHAO LIREN
IPC: C08L77/04
Filed: 1999-03-09
Abstract: A high temperature PTC device comprising a polymeric conductive composition that includes nylon-11 and a carbon-based particulate conductive filler has a switching temperature greater than 150°C, preferably between about 160°C and 200°C. The composition demonstrates a high PTC effect (at least 10 3, and more typically 10 4 to 10 5 or greater) and a resistivity at 25°C of 100 .OMEGA.cm or less, preferably .OMEGA.cm or less. High temperature PTC devices that comprise nylon-11 or nylon-12 compositions and that are manufactured by extrusion/lamination demonstrate good thermal and electrical stability compared with those manufactured by compression molding and do not require composition crosslinking for stability, although crosslinking may be used to further improve stability. The use of a high temperature solder for attaching electrical terminals to the device improves the PTC properties of the device.

Patent CA-2270931-A1 (CA)
Inventor: GOHEEN GREGORY L
IPC: H04Q11/04
Filed: 1997-11-06
Abstract: Dans des systèmes actuels de téléphonie à fréquences vocales, de télédistribution, et de réseaux sans fil, le trafic est découpé en voies à la fois pour l'accès et pour le transport, ce qui nécessite l'affectation d'une largeur de bande fixée de bout en bout pour la durée d'une connexion de service. Cette affectation des voies constitue un gaspillage de ressources dans des cas où des services multiples exigent des largeurs de bande et des durées d'occupation variables, ou lorsqu'un service produit du trafic de type par rafale. La présente invention permet de résoudre ces problèmes par l'apport d'un accès multiservices flexible et adaptable aux réseaux. Des demandes de clients sont vérifiées par un trafic de surveillance sur un accès local lors d'une demande de connexion et/ou au cours de la connexion établie, et l'accès local est configuré en fonction des exigences de transmission. Le trafic client est séparé et acheminé vers le réseau approprié. L'un des modes de réalisation utilise la programmation 2B1Q, et met en oeuvre un nouveau protocole pour réaliser les fonctions selon l'invention.
Patent CA-2271231-A1 (CA)
Title: Electrical switching apparatus with improved contact arm carrier arrangement
Inventor: SISSON GLEN CHARLES
IPC: H01H73/04
Filed: 1999-05-07
Abstract: The contact fingers of electrical switching apparatus have radial convex surfaces centered on the pivot pins which seat on concave surfaces in the molded contact carrier to transmit bending loads on the pin into the carrier. A seal member which snaps onto the end of the pivot pin has fins which extend between the contact fingers to block flow of arcing gases through the carrier. For lower current ratings, some of the contact fingers are replaced by annular spacers which also transmit bending moments into the carrier and restrict gas flow. A stop ledge on the carrier against which the contact springs bias the contact fingers has a recess which allows the center fingers to project farther toward the stationary contacts so that the arc toes on these fingers are the last to separate on opening and the arc is concentrated on them. The drive pin connecting the carrier to the operating mechanism has flats which key it for engagement in a slot in the carrier for installation and removal only with the carrier pivots lifted out of their bearing pockets by removal of the rear casing.

Title: Stereoselective reduction of carbonyl compounds
Inventor: CAIN ROBERT O
IPC: C07C323/41
Filed: 1999-06-04
Abstract: A process for the stereoselective reduction via a Meerwein-Ponndorf-Verley (MPV) reaction, of a carbonyl compound to the corresponding alcohol. A preferred starting carbonyl compound is a ketone compound wherein the carbonyl carbon is prochiral. The starting carbonyl compound is contacted with an MPV mediator such as aluminum isopropoxide. The reaction is conducted under mild conditions, e.g. temperatures of about 50°C or less, for less than four hours, and is capable of producing an excess (about 90% to about 97% or more) of a desired optically active chiral alcohol. The mild reaction conditions preserve the optical orientation of other asymmetric centers in the carbonyl compound starting material. Steroselective and stereospecific reactions for producing desired optically active alcohols are useful for the preparation of intermediate and final pharmaceutical products.
