Abstract: A flexible feeder conveyor system for removing material from a stockpile and transporting the removed material to a fixed conveyor. The system includes an underconveyor positioned below an excavator and having a loading hopper attached to its forward end to receive material and transport it beneath the excavator a rearward end of the underconveyor. A string of trailing conveyors is towed behind the underconveyor with the last trailing conveyor having its rearward end attached to a stationary terminal support positioned at the fixed conveyor. The underconveyor, the trailing conveyors, and the terminal support are connected together using transition hoppers. Each transition hopper includes an upper hopper mounted to the raised rearward end of the forward conveyor, and a lower hopper mounted to the forward end of the next rearward conveyor. The forward end of the conveyor is rollingly supported by a pair of caster wheels. The upper and lower hoppers are connected together for rotation through both a horizontal plane and a vertical plane. The horizontal rotation is permitted by constructing the upper hopper with an annular support portion and a housing portion rotatably supported thereabove by an annular bearing.      The vertical rotation is permitted by a pair of pivot pins attached to the annular support portion which are loosely received within corresponding upwardly opening slots in a housing portion of the lower hopper to permit the upper hopper to pivot with respect to the lower hopper.

Patent CA-2087660-A1 (CA)
Inventor: COLUMBUS PETER S
IPC: C08F2/16
Filed: 1993-01-20
Abstract: A water based thixotropic adhesive gel is disclosed which consists essentially of: water;   partially hydrolyzed polyvinyl alcohol,  or wherein a portion of the polyvinyl alcohol is replaced with  polyvinylpyrrolidone;   a  water-soluble  high  viscosity thickening agent polymer which is compatible with the polyvinyl alcohol and which imparts thixotropic properties to the gel; a water-soluble plasticizer for the polyvinyl alcohol; and a water-soluble defoamer in proportion of ingredients so that the viscosity of the adhesive will break down when a flexible tube or squeeze bottle dispenser is finger-pressed and have a sufficiently low viscosity to allow for easy extrusion from an orifice having a diameter of about 0.06 to 0.15 inches.  When pressure is released, after  the  desired  amount  of  adhesive  has  flown  out  of  the dispenser,  the adhesive quickly reverts to very close to its original gel state so that it will not run on a vertical surface on porous and semiporous surfaces such as paper.   An article of manufacture is also provided whereby the adhesive gel  containing the above ingredients is in a flexible dispenser from which the adhesive can be dispensed by finger-pressure.

Abstract: A skate blade finishing tool includes a holder adapted to be hand-held by a user.  The holder includes at least one slot therein.  Arranged in the slot is a strip of leather.  In use, the leather strip in the slot is rubbed along the length of a sharpened skate blade in a predetermined number of passes.  The leather strip removes foreign material redeposited by skate sharpening processes and small burrs remaining on the blade surface and smooths the skate blade surfaces.  When using the skate blade finishing tool to finish a skate blade, the detrimental effects of the sharpening process are removed to  provide  a  safe  skating  blade  that also  permits improved skating performance when using the finished blade.

IPC: B22D11/053
Filed: 1992-09-22
Abstract: In a process of withdrawing castings while vertically oscillating a mold formed with long side walls and short side walls in vertical continuous casting, the long side walls are separated from the castings by operating a hydraulic cylinder 4 in the time zones for which the castings are applied with a large frictional force. On the contrary, the separated long side walls are made close to the castings in the other time zones for which the castings are not applied with the large frictional force. By repeating the separation and approaching of the long side walls, it is possible to obtain the castings reduced in the depths of oscillation marks and suppressed in segregations at oscillation mark trough portions.

Abstract: The process  for determining the best communication route from a source end station to a destination end station is distributed over both source and destination network nodes. Network nodes, at the interface between a wide area network (WAN) and each subnetwork, contain access agents to control the communication flow between the wide area network and an end station in the subnetwork.  The task of selecting the best route between two end stations is distributed between the  access  agents  at  the  WAN  interface  in  the  first subnetwork,  and the access agents at the WAN interface in the  second  subnetwork.   Each  access  agent  at  one  WAN interface obtains the best route from itself to the end station in its subnetwork.  Each access agent at the other WAN interface finds the best route from each access agent at the first WAN interface through itself to the end station in its subnetwork.   One designated access agent collects all the best route information.  This best route information is concatenated,  and  the  route  with  the  least  weight  is selected as the best route between end stations.

Abstract: A method and apparatus for preparing graphic products utilizes a printer to print on sheet material and a cutter to cut the sheet material with the printed material within the periphery of the cut edges. Both the printer and the cutter are controlled by machine readable data having a common data base so that the printed material and the cut material correspond positionally in the final graphic product. The printer is a thermal printer that places the printed material on a strip of sheet material generally before the sheet material is cut, The thermal printer utilizes a donor web bearing a transfer ink to create enhanced printed images on the sheet material with half tones, color and other attractive features. The printer is controlled to regulate a number of printing parameters through coding on a cassette in which the donor web is supported.

Abstract: Self-locking pipe anchors for anchoring pipes to structural members and particularly for anchoring air lines and other train pipes to structural members in the underframes of railway cars. Each pipe anchor includes a pair of interlocking members for clamping a length of pipe therebetween. One of the members is a base member which is generally saddle-shaped and adapted to be welded or otherwise secured to a structural or frame member to which a pipe is to be anchored. The base member has a pair of ears or flanges extending along opposite sides and juxtaposed to the end of at least one of the ears there is a protuberance having a camming surface opposing the adjacent end of the ear. The other member of the pair is a wedge which is adapted to be driven into self-locking assembly with the base member so as to clamp a longitudinal length of pipe therebetween. The wedge member has channel-like formations extending on opposite sides each of which embraces one of the ears when the members are assembled. Pit least one of the channel-like formations has an integral locking tab the distal end of which engages the camming surface when the wedge member is driven into assembled relationship with the base member.      Upon such engagement, the locking tab is automatically bent so as to have locking engagement with the adjacent end of the adjacent ear thereby securing the members in assembled relationship with the length of pipe clamped therebetween.

Abstract: A cabinet door or doors are each hingedly mounted to the slide brackets of a pair of slide track assemblies which, in turn, are secured to a side wall of a cabinet.      A pair of inelastic cables of substantially the same length connect the upper and lower slide brackets in a prescribed configuration to prevent skewing of the slide brackets at all times. One of the cables extends rearwardly from the upper bracket across an upper rear pulley, downwardly and forwardly around a lower front pulley and back into the lower bracket. The other cable follows the opposite path from the upper bracket forwardly around an upper front pulley, downwardly and rearwardly around a lower rear pulley, and forwardly into the lower bracket. Because the cables are of equal length, they insure that vertical alignment is maintained.
