Patent CA-2112452-A1 (CA)
Title: Enhanced Data Formats and Machine Operations for Enabling Error Correction
Inventor: KARP JAMES M
IPC: G06F11/10
Filed: 1989-10-02
Abstract: A record medium, such as a magnetic tape, optical disk, magnetic disk, and the like stores data signals and error redundancy signals.  Resynchronization signals are inter-leaved between the recorded signals such that the error redundancy signals are usable to correct signals recorded between such interposed resynchronization signals wherein no error redundancy signals are recorded.  Error pointing redundancy signals are recorded between all of the resynchro-nization signals for pointing to signals in error for enhancing the error correction. Such error pointing signals can be cyclic redundancy check (CRC) signals.  Controls for taking advantage of the above-described arrangement are also described.  Reframing and clock synchronization controls are also disclosed.

Patent CA-2115096-A1 (CA)
Inventor: DAUGHERTY THOMAS H
IPC: H04Q3/58
Filed: 1994-02-07
Abstract: A communications switch (311) communicates a message to a particular access network endpoint (OE i) by forwarding an identification of that endpoint along with the message, link-by-link, through the access network, the forwardingbeing accomplished by using previously stored routing information identifying, at the switch and at each cross-connection point (350, 370), a particular downstream link over which the endpoint can ultimately be reached. The links (345, 365) connecting the cross-connection points are time-division-multiplexed links supporting digital loop carrier and fiber-in-the-loop communications. The routing information is generated and stored automatically by having each network elementreport information about itself upstream into the network.
Patent CA-2117500-A1 (CA)
Title: Automated document handling system
Inventor: VEN DE VEN JOHN
IPC: B65B25/14
Filed: 1994-08-16
Abstract: Documents printed by high speed laser printers are automatically handled to verify, track, handle, and deposit them in appropriate shipping containers.  The system is modular so that it can be configured to suit the needs of a wide variety of users, and includes document transport conveyors, transfer conveyors, and container transport conveyors.  A paper sheet having bar coding is associated with each group of documents and the bar coding is sensed to determine where to route the document (what shipping container it should be placed in), and also optionally other document handling procedures, such as plastic shrink wrapping and/or banding.  Documents are conveyed to a number of different filling stations with containers passing underneath the filling stations.  When the destination bar coding on a group of documents at a filling station matches the bar coding on the container underneath that filling station, dump paddles are activated to drop the group of documents into the container.  Prior to operation of the dump paddles, the size of the group of documents and the remaining volume in the container are both sensed to be sure the group of documents will fit in the container.  Containers that are determined to be full are transferred to a shipping loop for transportation by trucks or other shipping options.

Inventor: FARLEY HERB M
IPC: F16C11/06
Filed: 1994-03-29
Abstract: ABSTRACT OF THE DISCLOSURE   The present invention concerns a self-aligning coupling structure for releasably connecting a rear end of a feeder assembly to a frame of an agricultural harvester such as a combine and the like. The self-aligning coupling structure includes a pair of releasable couplings laterally spaced from each other on opposite sides of the feeder assembly and combine frame. Each releasable coupling includes first and second apertured coupling elements. One of the apertured coupling elements is provided on and extends from the combine frame while the other apertured coupling element is provided on and extends from a housing of the feeder assembly. The coupling elements each have complementary guide surfaces provided thereon. When the feeder assembly is to be coupled to the combine frame, the guide surfaces on the respective coupling elements of each releasable coupling cooperate with each other to self-align both horizontally and vertically the apertures in the coupling elements relative to each other thereby facilitating the passage of a pivot pin through the aligned apertures so as to releasably connect the feeder assembly to the combine frame for pivotal movement about the axis of the pivot pins.

Title: Process for measuring the flow rate of thick matter pumps
Inventor: SCHLECHT KARL
IPC: G01F3/16
Filed: 1993-02-04
Abstract: PROCESS FOR MEASURING THE FLOW RATE OF THICK MATTER PUMPS                           ABSTRACT A process and device are disclosed for determining by a measurement technique the flow rate of a substance conveyed by means of a thick matter piston pump (1) through a delivery pipe (22).  The thought at the basis of the invention is that the filling level of the delivery cylinder, which is required for accurately determining volumetric flow, may be inferred from the variations of the pressure in the delivery pipe.  Feeding pressure in the delivery pipe (22) is thus continuously or periodically measured at predetermined time intervals by means of a pressure sensor (54).  The interval between successive pressure strokes, used to determined the number of frequency of strokes, as well as the filling level of the delivery cylinder, used to determine the actual delivery volume per pressure stroke, are both derived from the time-dependent amplitude characteristic of the measured delivery pressure.
