Title: Rotating display
Inventor: BENJAMIN OLIVIER
IPC: A47F5/02
Filed: 1990-03-30
Granted: 1995-11-28
Abstract: Rotating displays include rotation mechanisms which allow the displays to be easily rotated by consumers, yet automatically returned to one or more desired positions when released by the consumer. Holders for the display are affixed to turntables rotatably mounted upon a base wherein the turntables are attached to a biasing means capable of exerting a sufficient torque upon said turntable, relative to said base to cause an angular acceleration of said turntable toward a predetermined desired orientation.  In preferred embodiments, the amplitude of the torque may be adjusted, depending upon the moment of inertia of the display, to cause a predetermined angular acceleration.  The number and placement of equilibrium orientations may be selected based upon the desired geometric configuration of the display with which the rotation mechanism is to be used.

Title: Combination process for hydrogenation and isomerization of benzene- and paraffin-containing feedstocks
Inventor: HAIZMANN ROBERT S
IPC: C07C5/27
Filed: 1991-03-21
Granted: 2001-12-18
Abstract: The benzene content in a gasoline pool is reduced by a process that hydrogenates a benzene-containing isomerization zone feedstream. In addition to reducing the benzene concentration, the hydrogenation zone is also used to heat the isomerization zone feed and thereby eliminate the need for an isomerization zone heater. The process employs mild saturation conditions which eliminates hydrocracking and prevents the loss of isoparaffin yield. Additional cyclic hydrocarbons produced by the saturation of benzene can be processed in the isomerization zone for ring opening to increase the available paraffinic feedstock or the isomerization zone can be operated to pass the cyclic hydrocarbons through to a product recovery section.

Patent CA-2066693-C (CA)
Title: Method for the fabrication of a composite structure
Inventor: RYYNAENEN SEPPO ILMARI
IPC: E01D21/00
Filed: 1990-09-21
Granted: 2000-04-11
Abstract: The invention relates to a method for the fabrication of a composite structure as a combination of a profile plate (1) and concrete. The profile plate (1) is usually a steel profile plate. Concrete is brought to the composite structure by spraying concrete (4) onto the surface of profile plate (1). Prior to the spraying of concrete, the relatively light profile date (1) can be placed at a composite structure building site. The spraying of concrete can be effected step by step and layer by layer by allowing the layers to set at lease partially between the spraying steps. Thus, the inherent load-bearing capacity of the structure increases as its weight increases.

Filed: 1992-06-30
Granted: 1998-11-24
Abstract: There is disclosed a video graphics system and method for creating variable width lines such that the lines may be easily edited.  As a line image is created, a center point of that image along its length is temporarily established having width information at various points.  This width information is used to create an outline of image of the desired shape, the outline having point data spaced at intervals.  This point data can then be edited by a user to create different shapes.  In situations where a pressure sensitive stylus is used to create the variable length line, a look-back technique is employed to insure that the line remains wide at the end point even though the user is reducing pressure as the system is removed from the pad.

Abstract: An elongated drawbar tension element is provided for the conveyor chain of an en masse conveyor. The drawbar includes a hollow hub at one end for receiving an enlargement at the other end of an adjacent drawbar element coupled thereto to form a chain.  The side faces of the hollow drawbar hub are formed with tapered dovetail shaped grooves for receiving complementary tapered dovetail shaped tongues formed on the inboard sides of transversely extending conveyor flights.  The tapered tongue and groove connection is self-tightening in normal use and the complementary dovetail configuration thereof prevents lateral separation of the conveyor flights from the drawbar hub.  An adhesive material may be applied to the self-tightening connection to prevent loosening thereof and separation of the flights from the drawbar elements when the conveyor chain is subjected to vibration, irregular loads or is moving in a downward direction.

Abstract: A method of immobilizing a chemical specie in a three-dimensional, crosslinked matrix. The method involves bringing together in covalent bonding proximity a desired chemical specie and a polymeric coupling compound having at least two latent reactive groups per molecule, each latent reactive group being capable when activated of covatently bonding to another coupling compound molecule or to the chemical specie. The chemical specie desirably is free of latent reactive groups that are activated upon activation of the latent reactive groups are simultaneously activated to cause formation via covalent bonding of a three-dimensional molecular network in which molecules of the chemical specie are covalently bonded to molecules of the coupling compound and molecules of the coupling compound are covalently bonded to each other. Preferably, the three-dimensional matrix is formed as a coating upon a surface to which covalent bonds are formed upon activation of the latent reactive groups of the coupling compound.

Title: Path hunt for efficient broadcast and multicast connections in multi-stage switching fabrics
Inventor: PAWELSKI ROBERT LEE
IPC: H04Q11/04
Filed: 1993-10-27
Granted: 1998-03-10
Abstract: To efficiently implement the algorithm for branching each broadcast call as close to the output of a multi-stage switching fabric (100) as possible, the path hunt (FIG. 12) for a call path is performed by examining the actual contents of control memories (305, 1701) that control the switching stages of the switching system, in order to determine whether --and if so, where-- the desired call path may be branched from an existing call path inside of the switching system. For efficiency and speed, the examination is performed by monitoring control memory contents being read out for the purpose of controlling the switching stages, and contents of control memories of multiple stages are monitored in parallel using dedicated monitoring hardware (FIGS. 14, 15). To avoid the need to examine the control memories' contents in order to determine how much of a call path can be torn down (FIG. 13) without breaking call path segments shared with other existing call paths, separate counts (801, 901) are kept of instances of present use of connections between stages of the switching fabric, which counts are incremented upon creation of any branching paths that use these connections and are decremented upon breaking of any branching paths that use these connections.
