Patent CA-2055250-A1 (CA)
Inventor: TANAKA AKEO
IPC: B29C41/14
Filed: 1991-11-12
Abstract: A method of manufacturing a open-back type working glove.  A fiber-made glove is fitted on a dipping hand block, and same is dipped in a stock solution of a rubber latex composition.  After the glove and hand block is removed from the stock solution, the solution deposited on the glove in an open-back fashion is heated so as to allow it to be semi-vulcanized.  Then, the glove is removed from the dipping hand block and is immersed in water or warm water to allow the rubber coat in semi-vulcanized condition to swell and soften.  Finally, the glove is fitted on a setting hand block having a thumb portion projecting considerably beyond the palm portion, with other four finger portions curved toward the palm portion, and the rubber coat is heated for final vulcanization.

Inventor: HELMKAMP DAVID J
IPC: H04Q3/58
Filed: 1992-01-09
Abstract: A wireless PBX system provides ease of installation without site engineering or trial-and-error placement of components within the system. In itsbasic form, the wireless PBX system consists of only two types of components: a control unit including an radio frequency transceiver; and fixed location terminals, such as telephones and voice/data stations, which also include radio frequency transceivers. Portable handsets are optionally included in the system to allow for customer mobility. Installation of the PBX system is achieved simply by placing the system components in the desired locations at a premises, plugging them into line power, and performing some simple programming steps including a final step of initiating an automatic configuring process. Through this process, the system automatically configures itself for optimum operation in view of the radio environment and placement of components within the system at the customer premises. In the operation of this process, the control unit exchanges various radio messages with the terminals, decides which terminals should also serve as repeaters for linking those more distantly located terminals, and determines the appropriate frame structure for the system. A positive display indication at the control unit, following the end of the automatic configuring process, shows that all terminals have been linked and that the system is operating normally.

Filed: 1992-01-17
Abstract: Abstract Of The Disclosure A coiled tubing set inflatable packer, bridge plug and releasing tool therefor.  The packer and bridge plug comprise an adapter With a mandrel slidably disposed therein.  A pressure actuated piston releases a locking ball between the mandrel and adapter during an inflation cycle and allows movement of the mandrel such that the locking ball again locks the mandrel and adapter when the mandrel is moved to a sealed position wherein the inflatable packer element is sealingly closed.  The inflatable packer of the present invention comprises a valve for opening a central passageway through the packer.  A J-slot in the packer allows a plurality of inflation cycles to insure proper setting of the packer prior to actuation of the valve.  The bridge plug of the present invention comprises a bypass passage therethrough which may be opened by upward movement of a central mandrel.  A releasing tool is provided for releasing the packer or bridge plug in the well bore after setting of the packer element.  A releasing plug or releasing ball is used to move a releasing mandrel and disengage locking dogs from an overshot on the releasing tool so that the releasing tool may be removed from the well bore.

Title: Shunt trip switch operator
Inventor: ERICKSON WILLIAM C
IPC: H01H9/10
Filed: 1992-08-25
Abstract: A trip-free operating mechanism for a load break switch of the type having a fixed contact engageable by a movable contact between a fully closed position and a fully open position.  The operating mechanism includes an operating lever connected to the movable contact and rotatable about a shaft to move the contact between its open and closed positions.  A follower rotates on the shaft into and out of contact with the operating lever.  A closing spring biases the operating lever and the follower towards each other.  An opening spring drive connects to the follower to drive the follower to its switch contact open position.  A first latch holds the operating lever and follower apart against the force of the closing spring when the operating lever is in its switch contact closed position.  A manual and a solenoid actuated strip mechanism are provided to release the first latch to allow the closing spring to rotate the follower into engagement with the operating  mechanism and to rotate the spring drive to quickly drive the operating lever to its switch contact open position.  A second latch retains an operating handle in its closed position until the closing spring rotates the follower into engagement with the operating mechanism. The operating handle is nudged to fall by gravity to its switch open position when the follower rotates to its-switch contact open position.  The operating handle engages the follower in the switch contact open position to rotate the follower to near its switch closed position while the operating lever is latched in the switch open position.  The operating lever latch may be released by rotation of the follower or by actuation of a second solenoid.

Title: Drawing aid
Inventor: GOSSELIN MARCEL J
IPC: G09B11/00
Filed: 1993-02-26
Abstract: ABSTRACT   The apparatus assists a person in drawing a three-dimensional object on a flat translucent material such as paper. The apparatus consists of a transparent flatplastic screen within an adjustable upright frame. An adjustable sighting devicewith an eyepiece projects from one edge of the frame. A three dimensional object is placed beyond the transparent screen so that it can be viewed through the eyepiece and screen. The sighting device stabilizes the artist's viewing position and facilitates the tracing of the object upon the plastic screen with a light-coloured or white wax crayon. A sheet of paper or other translucent material is then placed over the drawing on the plastic screen. A light source is directed into one edge of the plastic screen thus making the white wax drawing lines visible through the paper or other translucent material. Following the illuminated lines the artist can now trace upon his paper with a pencil, pen or other means and thus transfer to his paper or other translucent material an accurate two-dimensional rendering of the observed three-dimensional object.
