Abstract: ABSTRACT            A steam sterilization system for a filling machine having dispensing nozzles connected to a source of product supply, the sterilizing system including a novel autoclave apparatus and a novel condensate purge system.  The auto-clave structure causes sterilizing steam to flow downward through the inside of the dispensing nozzle to its open ended bottom where it reverses and flows upward between the inside face of a reversing tube and the outside face of the dispensing nozzle to a series of holes through the sidewall of the reversing tube where it emerges and goes down between the outside face of the reversing tube and the inside face of the autoclave shell thereafter passing down into a steam and condensate line.  Condensate formed within the dispensing tube drips out the bottom of the dispensing tube and through an aperture at the bottom of the reversing tube, the condensate effectively sealing the bottom of the reversing tube to steam. The condensate purge system includes a back pressure and con-stant bleed valve having its intake connected to the autoclave steam and condensate line, its outlet connected to a discharge line, and an actuatable by-pass purge valve connected from an internal point in the bleed valve to the discharge line.  The purge valve is controllably actuated to effectively drain the bleed valve to prevent the back build up of condensate in the system without interfering with the sterilization operation.

Abstract: ABSTRACT        Apparatus For Decoding Phase Encoded Data Apparatus is disclosed for reading phase encoded digital datafrom a nine-track magnetic tape which apparatus includes timing circuitry for deriving a clock signal from the recorded data.  A portion of the timing circuitry is associated with each track on the tape and automatically accomodates, without generating errors, phase changes in the derived clock signal in that track caused by speed variations in the magnetic tape transport and due to bit shifts caused by certain data patterns.   Tape transport speed variations are sensed and the derived clock rate is corrected by a digital phase-locked loop which uses a counter that is clocked at a constant rate to determine the timing ''window'' during which the circuitry looks for signal transitions on the magnetic tape.  A running average of the count remaining in the counter at the time when a transition actually occurs is used to adjust the counter starting value until equilibrium is established.   The circuitry accomodates clock signal phase changes caused by bit shifting by calculating an expected arrival time for a data transition and varying the width of the timing window depending on whether the data transition is received either prior to or subsequent to the expected arrival time.

Abstract: Abstract Vehicle Multiplex System Having Protocol/Format For Secure Communication Transactions An improved serial data protocol/format is provided in a serial multiplex system for use in an automotive vehicle electrical system which is subject to electrical noise.  The protocol/format includes successive transactions between a master controller and respective remote controllers each connected to a serial multiplex bus.  Each transaction is bidirec-tional and includes a command message transmitted by the master controller and a reply message normally transmitted by an answering remote controller. Each command message is preceded by a multibit SYNC byte.  The command message includes an address byte (for a particular remote controller), a command byte, and an error check such as a cyclic redundance check byte passed on the address and command bytes.  The reply message includes the address byte of the replying remote controller, a response byte indicative of its response to the command byte, and an error check such as a cyclic redundancy check byte based on the reply address and response bytes.  The master controller may be caused to repeat the transmission of a command message if the address bytes, the command/ response correlations or error check bytes are not verifiable, thereby enhancing the system's ability to detect and/or reject errors as might be occasioned by noise.

Abstract: METHOD AND APPARATUS FOR FUMIGATING      BULK-STORED COMMODITIES                    ABSTRACT OF THE DISCLOSURE           A method and apparatus are provided for placement of selected quantities of gas-producing solid fumigant at selected locations within the depth of a bulk-stored commodity within a storage compartment, such as grain loaded into the hold of a ship.  The invention comprises a fabric sleeve projecting downwardly into the grain with a closed lower end at a selected depth, and an open filler pipe received into the sleeve through which a selected quantity of fumigant is poured.   The filler pipe is withdrawn to leave the fumigant at a selected depth within the sleeve, whereupon the grain compresses against and closes upper unfilled sleeve portions thereby isolating the fumigant at a selected depth within  the grain where it produces penetrating toxic gases to exterminate pests.   In one form, the sleeve and filler pipe are inserted as an assembly to a relatively shallow depth within the grain subsequent to loading of the hold.   In another form, the sleeve and filler pipe are sized to project for a substantial depth into the grain and are suspended in place prior to loading of the hold, with a guide tube being supported within a substantial upper region of the sleeve to define an open column through which the filler pipe may be withdrawn without  compressive  resistance  from the grain.  In either form, residue from the solid fumigant is contained within the sleeve for easy separation and removal from the grain for disposal.

Abstract: ABSTRACT SCAN CONVERSION APPARATUS AND METHOD An improved scan converter for converting received echo signals representative of the amplitude of ultrasound energy returning from sampled points along a plurality of spaced apart paths distributed in an image space into signals to be displayed as display pixels in a raster scan display system. The scan converter includes a scan data memory for storing the received echo signals in quadrants of the scan data memory. Each quadrant is associated with even and odd numbered paths and sample row combinations. Sample rows are related to sample points along the spaced apart paths. The scan converter further includes a circuit for determing a gray scale value to be assigned to each selected display pixel based on a predetermined combination of four received echo signals adjacent the selected display pixel and chosen from the quadrants of the scan data memory. The improved scan converter is capable of operation in both linear and sector scan modes, and, when in the sector mode, over 90° and 180° sectors. Variable scaling between the image space and display space and correction of the hose error when the scanning system employs an oscillating wobbler scan head are provided. Various techniques for converting display pixel rectangular coordinates into polar coordinates in real time for raster scan display are employed.
