Title: Measuring the speed of ultrasound in a moving web of paper
Inventor: BURK GARY N
IPC: G01H5/00
Filed: 1987-05-11
Granted: 1991-09-10
Abstract: ABSTRACT     The invention provides apparatus and methods for producing and communicating low-noise signals that, when combined with known distances between a first transducer and each of a plurality of second transducers, enable measurement of the speed of ultrasound in a moving web of paper.  The invention employs a hollow cylinder having electronic circuitry in its interior.  The first and second transducers are disposed in the cylinder and have portions which protrude above the surface of the cylinder for contact with the web.  The first transducer receives electrical pulses and delivers corresponding ultrasonic pulses to the web that propagate through the web and are received by the second transducers.  The second trans-ducers then deliver corresponding electrical signals which correlate with the speed of ultrasound in the web and may be communicated to receptors which are external to the cylinder.       The communicated signals may be further conditioned and processed to produce a measurement of the speed of ultrasound in the web.

Title: Continuously variable power converter
Inventor: KURTOSSY CSABA G
IPC: F16H37/06
Filed: 1987-12-14
Granted: 1991-01-02
Abstract: CONTINUOUSLY VARIABLE POWER CONVERTER                ABSTRACT Disclosed is a transmission which may advantageously utilize planetary gear assemblies. Planetary gear assemblies are characterized by no less than three independently rotatable members, each of which has associated therewith separate kinetic and kinematic properties, that is force and velocity components.  These force and velocity components associated with one another create a power stream.  By appropriate variation of parameters within several planetary gear assemblies comprising a transmission, including at least one parameter that is continuously and controllably variable, the kinetic, kinematic, or both, properties of the several power streams are manipulated so that all but one are eliminated thereby leaving as the sole surviving power stream one that has at least one kinetic or kinematic property which is continuously variable to form the output power stream of the transmission.

Title: Hierarchical encoding method and apparatus for efficiently communicating image sequences
Inventor: ERICSSON S STAFFAN
IPC: H04N19/94
Filed: 1988-06-01
Granted: 1994-12-13
Abstract: A method and apparatus for encoding interframe error data in an image transmission system, and in particular in a motion compensated image transmission system for transmitting a sequence of image frames from a transmitter to a receiver, employ hierarchical vector quantization and arithmetic coding to increase the data compression of the images being transmitted.  The method and apparatus decimate an interframe predicted image data and an uncoded current image data, and apply hierarchical vector quantization encoding to the resulting pyramid data structures.  Lossy coding is applied on a level-by-level basis for generating the encoded data representation of the image difference between the predicted image data and the uncoded original image.  The method and apparatus are applicable to systems transmitting a sequence of image frames both with and without motion compensation.  The method and apparatus feature blurring those blocks of the predicted image data which fail to adequately represent the current image at a pyramid structural level and shifting block boundaries to increase the efficiency of the vector quantization coding mechanism.  The method further features techniques when gain/shape vector quantization is employed for decreasing the data which must be sent to the receiver by varying the size of the shape code book as a function of the gain associated with the shape.  Thresholding and the deletion of isolated blocks of data also decrease transmission requirements without objectionable loss of image quality.

Title: System for loading patterns of articles into containers
Inventor: SCHNEIDER THOMAS C
IPC: A21C9/08
Filed: 1988-06-14
Granted: 1991-04-16
Abstract: Abstract of the Disclosure A system for loading groups of articles into con-tainers includes an infeed conveyor which groups the ar-ticles into subgroups which are then selectively reoriented by a turntable-type orienting device.  The oriented subgroups are then conveyed to a transfer area where they are accumulated into elements of a predeter-mined pattern of articles.  A pusher sequentially push-es the pattern elements onto the lower reach of a window conveyor disposed at a loading station.  A con-tainer conveyor runs beneath the window conveyor to de-liver an empty container to the loading station, lifting means then raising the empty container to a loading position immediately beneath the support reach.          The window conveyor is then operated to drop the pat-tern of articles through the window thereof into the container.  As the window conveyor continues its move-ment a pusher on the leading end of the conveyor sec-tion thereof pushes the loaded container onto a discharge slide assembly which then tilts downwardly to allow the filled container to slide onto an outfeed con-veyor which may convey loaded containers to downstream apparatus, such as a bottom-up stacking mechanism.
