Inventor: STRELIOFF WILLIAM P
IPC: G01G19/10
Filed: 1993-05-21
Granted: 1995-07-04
Abstract: A mobile weighing system for use on a truck or trailer to weigh a load carried by the truck or trailer.  A load support frame supports a load and is positioned over the frame of the truck or trailer. A plurality of weighing cells are mounted over the truck or trailer frame in such a manner as to bear an approximately even distribution of the load. Each weighing cell comprises a lifting mechanism having an extended position and a rest position, a vertically disposed tension load cell and a linkage assembly coupling the lifting mechanism and the load cell to cause an upward force on a top end of the load cell when the lifting mechanism is extended. The bottom end of the load cell is attached to the support frame so that the support frame is suspended by the load cells when the lifting mechanisms are extended. The lifting mechanisms and linkage assemblies of the weighing cells are attached to the truck or trailer frame.    A lock down mechanism integral to the load cells secures the load support frame when the lifting mechanism is in a rest position.

Granted: 1999-08-31
Abstract: A method for providing a flexible method for applying computationally significant association information in graphical input systems to information data using unrecognized visual information is disclosed. A method is provided to mark and index user-produced information with special information designators called key objects which can later be used as access mechanisms into the user-produced notes, without recognition of the notes. Visually recognizable, but computationally unrecognized, image segments are designated key objects. A key object is assigned a unique identifier that is computationally distinguishable from other key object identifiers. Key objects are associated with other data objects by attaching the key object identifier to other data objects in a data structure. A key object is easily created and reused, and provides a flexible and powerful indexing tool into graphically significant information without requiring the use of expensive or sophisticated recognition algorithms.

Granted: 1998-05-26
Abstract: A boron-doped diamond resistance heater is provided herein. Such resistance heater includes at least one continual conductive line with ends, the lines and the ends being made of boron-doped single crystal diamond or polycrystal diamond. Insulating parts enclose the conductive lines, the insulating parts being made of non-doped diamond single crystal diamond or polycrystal diamond. Ohmic electrodes are formed on the ends of said conductive lines. When a voltage is applied between the electrodes, a current flows in the conductive lines, thereby generating Joule's heat, and the device acts as a heater. Since the whole device is made of diamond crystal, the heater can be of extremely small size. The heater has a high resistance against high temperature,especially in an anaerobic atmosphere. Moreover, such boron-doped diamond-resistance heater can be used in vacuum or in a liquid, since the insulating diamond layers are highly resistant against vacuum and liquids.

Patent CA-2156657-C (CA)
Inventor: BEAUCLERC RICHARD G
IPC: B61G7/10
Filed: 1995-08-22
Granted: 1999-06-15
Abstract: When slack-free railcar connector assemblies are placed under very high tensile loading, the connector assembly components will stretch and allow a typical "rigid" gravity wedge to descend into a fully seated position between the components and lock-in the tensile loads. The locked-in loads become additive in nature when successively encountered compressive loads are experienced by the connector assembly, thereby increasing the lateral drawbar angling forces, as well as accelerating coupling component wear. The wedge component of the present invention includes a means for vertically supporting and retaining the wedge in a holding position slightly above the normally fully seated position during the tensile loading, thereby eliminating the build up of tensile forces in the connector assembly.

Abstract: An apparatus for use in a service station to recover automotive fluids.  The apparatus comprises a reservoir attachable  to a  floor  surface  and  a catch  pan  for receiving automotive fluids flowing from under a vehicle being serviced.  The apparatus also comprises a hollow extensible arm means  between the catch pan  and the reservoir  forming  a  conduit  therebetween,  and  an articulated joint between the extensible arm means and the reservoir.  This articulated joint is flexible in a vertical plane as well as in a horizontal plane.  Thus the catch pan and the extensible arm means are movable between a first horizontal fluid recovery position and a second  vertical  compactly  stowed  position  above  the reservoir.   The reservoir of the apparatus also has a first drain valve and a second drain valve located above the first drain valve.  When the apparatus is used to recover several types of automotive fluids, those aqueous fluids such as radiator coolant may be firstly emptied from the reservoir through the first drain valve.  Then the petroleum based fluids can be emptied through the second drain valve even if a nominal volume of aqueous fluid remains in a lower portion of the reservoir below the second drain valve.
