Title: Process and Apparatus for Making a Plastic Bag with a Zipper
Inventor: DONOVAN TERRY J
IPC: A44B19/62
Filed: 1995-04-26
Abstract: In a continuous bag-making process, the film (12, 13) and zipper track (10) move intermittently through a bag machine in a continuous stream, so there is no end to the zipper track on which the slider can be inserted. In the present invention, in the intermittent motion-part of the bag machine, the zipper is cut apart at the location that is to be the edge of the bag, the ends formed by the cutter moved laterally relative to each other exposing the ends and the slide (11) is inserted over one of the exposed ends.

Patent CA-2202853-A1 (CA)
Inventor: WHITESELL RICHARD F
IPC: F16L55/04
Filed: 1997-04-16
Abstract: A gas or liquid pulsation dampening system is provided which minimizes the size of the vessel required to  effectively  dampen  gas  or  liquid  pulsations  while maximizing  the  dampening  effect.    The  gas  or liquid pulsation  dampening  system  comprises  a  novel  spring pulsation dampening valve and a vessel for housing the valve and for containing a gas or liquid.  The vessel is equipped with a pulsating gas  or  liquid  inlet  and a dampened gas  or  liquid outlet,  and  support means  for holding the spring pulsation dampening valve  in axial alignment with the dampened gas or liquid outlet.   The spring pulsation dampening valve comprises first and second ends, a stationary outer sleeve, and a spring loaded gas or liquid flow restricting tube positioned in the interior of the stationary sleeve for axial movement therein.  The gas or liquid flow restricting tube includes a gas or liquid intake at the first end of the pulsation dampening valve and a gas or liquid outlet at the second end of the pulsation dampening valve, and a spring operated pressure receiving means at the gas or liquid intake for receiving and sensing gas or liquid pressure. The spring of the spring pulsation dampening valve communicates with the pressure receiving means to hold the pressure receiving means  resiliently  against  increases  in  gas  or  liquid pressure.  As  gas  or  liquid  pressure  fluctuates, the pressure receiving means, including the gas or liquid flow restricting tube oscillate axially thereby increasing and decreasing the capacity of the vessel in opposition to pressure fluctuations.

Title: Method and apparatus for coding digital video signals
Inventor: RIEMANN UWE
IPC: H04N19/87
Filed: 1997-05-29
Abstract: For future digital television broadcasting and the  interactive communications  services  associated therewith, video data must be greatly reduced in terms of their volume of data by means of suitable coding devices.  One  coding method provided  for  this  is  the MPEG2 standard. If, during the coding, a change in the picture  scene  occurs  within  successive  Groups  of Pictures, no rational basis for the prediction of the B and P frames exists for the current Group of Pictures. As a result,  the reconstruction result in the decoder will remain unsatisfactory. According to the invention, such scene changes are detected and the first picture of the new scene is intraframe-coded.

Patent CA-2213310-A1 (CA)
Inventor: KRAFT WALTER
IPC: G03C5/08
Filed: 1997-08-19
Abstract: In a method for producing photographic copies, first copies are produced in a first pass in a first printer, and any second copies needed are produced in a second pass by a second printer which is calibrated to the first printer by means of a setup test method.  In this setup test method, the original-specific data ascertained in the first pass are delivered to a computing and control unit of the second printer.  With the aid of these original-specific data and with the aid of an original model adapted to the copying material, the requisite quantities of copying light are ascertained in the computing and control unit of the second printer, and the second copies are made. The developed second copies are subjected to an analysis.  Based on the analysis, the original model adapted to the copy material is optimized for the second printer until the second copies are substantially identical to the first copies.
Patent CA-2214254-A1 (CA)
Inventor: ROESE WILLIAM C
IPC: B62B5/04
Filed: 1997-08-29
Abstract: A steerable three-wheeled cart has a frame supported by a palr on non-steerable rear wheels and a steerable front wheel.  The front wheel is mounted on a steerable wheel carriage that is journaled to the frame for rotation of the carriage and wheel about a generally vertical axis.  A handle is pivoted to the wheel carriage to effect steering of the front wheel.  The handle mounts a braking member whose braking surface is curved both longitudinally and laterally so as to conform substantially to the curvature of the front wheel.  A braking force is applied to the front wheel by rocking the handle downwardly to cause the braking member to bear against the wheel while retaining the ability to steer the wheel with the handle.

Title: Method and apparatus for reducing storage requirements for display data
Inventor: TYLER WILLIAM B
IPC: G06K15/00
Filed: 1996-06-07
Abstract: A method and apparatus for reducing storage requirements for display data on a computer system (12). Data objects (22) to be displayed are organized into display lists and each data object includes an object type, such as text, graphic, and image. The data objects (22) are rasterized into an uncompressed band buffer and divided into non-intersecting bitmap regions each identified with one or more object types. Each non-empty region is assigned a compression algorithm dependent upon the type of the region and specified compression constraints. The regions are combined with each other into larger regions if appropriate, and each region is compressed using its assigned compression algorithm into a compressed band buffer, thus reducing the required storage space for the data objects. The compressed data is decompressed in scan line order with a selected decompression algorithm corresponding to the assigned compression algorithms to produce uncompressed output data. The uncompressed output data is supplied to an output display device (16) for display.
