IPC: B62D65/00
Filed: 1990-12-06
Abstract: BODYSIDE PANEL HANDLING CONVEYOR   ABSTRACT         A carrier is mounted for movement along a conveying path defined by a pair of conveying rails, one of which has a relatively short gap at a work station.  A manipulator device is located at the work station and includes a relatively short conveying rail section which may selectively located to span the gap in the one rail or located in a position displaced from the rail.  An article support frame is mounted upon the carrier for pivotal movement about an axis parallel to the rials between conveying position and a transfer position.  A rail gripping device fixed to the support frame slides along the one rail to support the support frame in its conveying position during movement of the carrier along the rails.  When the carrier arrives at the work station, the gripping device engages the short rail section of the manipulator which is then actuated to displace the rail section from the rail to pivot the support frame to its transfer position in which an article supported on the support frame may be processed by tooling located a the work station.

Title: Hydroacoustic ranging system
Inventor: ROUQUETTE ROBERT E
IPC: G01S5/30
Filed: 1991-02-11
Abstract: Digital processing systems and methods of hydroacoustic pulse communications in offshore seismic exploration systems provide more efficient surveys with less critical equipment.  Thus hydroacoustic transceiver transducers towed in a set of streamers behind a vessel are accurately positioned under variable operation conditions with a geodetic reference point for more efficiently and accurately monitoring echo points for seismically identifying underwater formations. Spacings between transducers are found by calculating from pulse arrival times the transit times of hydroacoustic pulses.  Predetermined pulse shapes and carrier frequencies above 40kHz are accurately determined upon receipt by digitally sampling waveshapes to determine shape and timing the reception of identified pulse shapes at transducers which are transmitted from other transducers for computing separations between sending and receiving transducers.  Pulse transit time averaging avoids precise synchronization for simpler apparatus.  The carrier frequencies and associated high pass filters for received pulses eliminate hydroacoustic noise.  The digital pulse sampling and timing techniques simplify communications with associated data processing systems for seismic analysis and provide compact on-location electronic systems coupled to the transducers.

Patent CA-2043975-A1 (CA)
IPC: B60B25/02
Filed: 1991-06-06
Abstract: This is a friction welding method for joining a rim and a disc of a disc wheel and apparatus therefore wherein an outside material or a rim and an inside material or a disc, each of which is a component of a disc wheel, are joined together.   This friction welding apparatus comprises, typically, a mechanism for fixing firmly the circumference of one materi-al almost entirely circumferentially, a mechanism for rotat-ing another material, a mechanism for generating frictional heat between the two materials, with the inside material fitted into the outside material, by pressurizing the rotat-ed material to the fixed material.    This method employs a lap joint process instead of a butt joint process.  Either or both of the materials can be provided with a projection on the circumference.  A projec-tion absorbs the turning force, inertia force and braking force produced at the time of joining operation to prevent the above forces from being concentrated on a local portion of the materials in process.  This prevents the finished products from deformation.

Title: Hub assembly for collapsible structures
Inventor: BUCKLEY MICHAEL G
IPC: F16C11/06
Filed: 1992-05-13
Abstract: ABSTRACT         An improved form of connector for rods for collapsible structures is described. In the example hemispherical projections from either side of a tongue affixed to the end of a rod inserted in the connector serve as the pivot for the hinging action for moving the rod to the collapsed position. The improvement lies in the fact that when lateral and rotational stresses on the rod, or rods, joining the connector, give rise to reaction stresses from the troughs formed to receive the hemispheres, the curved contact surface between the troughs and the hemispheres will transmit these reaction forces back with components in all three spacial dimensions, thereby diffusing the reaction stresses and rendering the tongue less likely to stress failure than previous examples of such connectors, which were, prone to channelling the reaction stresses into one or two planes only. The present invention is also more likely to hold a solid expanded position than previous examples utilizing fully spherical joining parts on the rod-ends, which tend to allow exaggerated movement of the rod in all planes.

Title: System for non-contact colored label identification and inspection and method therefor
Inventor: WERTZ RONALD D
IPC: G01J3/50
Filed: 1992-05-21
Abstract: ABSTRACT       An optical inspection system which inspects for the presence of defects in colored labels placed, for example, on the side walls of cylindrical beverage cans.   The  optical  inspection  system utilizes  a conveyor  for  conveying  the  beverage  cans  in  a production line where such beverage cans typically are randomly oriented.  The  optical  inspection  system positions an optical head near the beverage cans as they move in the production line without physically interfering or interacting with the movement.   The optical head senses a preselected number of different colors which appear in a predetermined field of view of each moving can.  The cans being randomly oriented have different portions of the label visible in the predetermined  field  of  view  which  is  fixed  in position. The optical head produces analog electrical signals corresponding to the intensity of each sensed color.  A computer is utilized to process these analog electrical  signals  from  the  optical  head.    The computer  first  generates  a  number  of  two  color signatures based upon the selected number of colors. After sufficient cans have passed the optical head wherein all two color signatures are fully developed, the computer senses the colors from each successive subsequent can and compares it to the generated color signature.  If the sensed color pattern falls outside the generated color signatures, then the can fails and an air signal is generated.
