A method of cleaning potable liquid flow lines employing a high pH caustic cleaning solution or a low pH acid cleaning solution with a stable dye in sufficient concentration so as to have a visible color when the solution is further diluted. The cleaning solution is pumped through the lines. The lines then are flushed with clean water until no colored solution is discharged from the lines, indicating the lines have been purged of cleaning solution. The method can be used with draft beer, soft drink or other potable liquid flow lines to prevent inadvertent consumption of caustic cleaning solution along with subsequently dispensed potable liquid.

Beverage flow line cleaner with safety indicator and method of use

Apparatus for use with a tractor loader, and including a support, elongated teeth attached to a frame, a retainer above the teeth which is pivotable between upper and lower positions, and a push arm between the teeth and the retainer which is movable between retracted and extended positions. The apparatus can handle various types of bales of hay, straw, etc. It can also be used to lift and transport loose fibrous material. The retainer is pivoted downwardly to grip and hold the material on the teeth. When the retainer is pivoted upwardly, the push arm can be moved to its extended position to urge the material off the forward ends of the teeth.

Bale handling apparatus

The capacitance to ground of a metallic ornament is included in an oscillator. When a person touches the ornament, the period of the oscillator increases. The increased period causes a change of state of a bistable latch. In response to the change of state, a silicon controlled rectifier either provides a path for current through a lamp or prevents a flow of current therethrough. The metallic ornament is preferably a Christmas tree ornament or light.

In a ring-structured data communication network, in which plural data processing systems exchange data and control information on a full duplex peer to peer basis, systems are presently architected to assign at least three I/O subchannels (i.e. at least three device addresses) to respective ring interface adapters. At least two of these subchannels are dedicated for providing separate input paths from the ring to at least two associated program-assignable areas in their system's main store, and a third of these subchannels is dedicated as an output path from the system's store to the ring. Collectively, these subchannels can sustain two input transfer processes and one output transfer process concurrently. One of these input processes is associatable with a locked mode of adapter operations which provides a non-blockable path for data transfer from a selected (remote) station on the ring to the respective system's main store. In this mode the other input subchannel and the output subchannel permit the system to maintain full duplex communication with other ring stations in respect to network transactions/processes which may require priority attention. Information is sent on the ring in discrete information frames of variable bit length, each frame acknowledged by a response frame. In general, response frames have much shorter bit lengths than the information frames, enabling the systems to access the ring more efficiently than they would be able to if response and information frames had equal lengths.

Distributed data processing in ring-structured networks architected for

A method of initializing non-synchronous peer-to-peer data communication rings, and for effecting error recovery in such networks. On detection of error, each station operates in a purging configuration to clear the ring. In the purging configuration the station's receiving circuits are isolated and its transmitting circuits transmit 'clear' signals containing this station's own address as destination. These signals serve to purge all potentially erroneous information in all upstream stations which then are operationally connected to that station. If a loss condition is persistent the station operates first in a 'bypass' configuration for a third predetermined time interval, then in the purging configuration for the second time interval, and then resumes normal operation. In the bypass configuration the station's ring input is connected directly to its output and the (locally clocked) output of its transmitting circuits is connected to the input of its receiving circuits. This serves to restore reception clocking in temporary alignment with the local transmission clock source. When a station switches from purging mode to normal operation it resumes monitoring its reception synchronism. If is fails to develop synchronism it repeats the foregoing recovery procedure.

Method of purging erroneous signals from closed ring data communication

In a loop-structured communication system interconnecting a plurality of data processors without central controller, stations comprise modems which can start loop operation and achieve synchronous frame transmission around the loop through all participating stations. In an initialization procedure after system start or after loss of frame synchronization on the loop, modems select a temporary master station. The temporary master will adapt total loop delay to be an integer multiple of the basic frame period, and will transmit available frames. All active modems adapt their timing to the circulating stream of frames until the whole loop and all participating stations are synchronized. Synchronization conditions are continuously monitored in all stations to start resynchronization or initialization procedures if necessary. In a specific arrangement, the location of a loop failure which prevents establishment of synchronization can be determined. All initialization and synchronization operations are handled by the modems without participation by other functional units or by the host processing system of any station.
