Abstract: High speed dairy casing methods and apparatus assemble columns of filled containers arriving on two infeed conveyors, transfer one, two or more columns to an assembly ramp adjoining each conveyor, and then sweep the assembled columns from the conveyor and the ramp together across the ramp to an adjacent loading zone for casing, leaving the assembly ramp free for assembling succeeding columns while case loading is proceeding. Preferably two infeed conveyors deliver filled containers into two separate assembly zones with their ramps flanking a central loading zone, and a pusher with two extended positions propels each single column from its conveyor onto the assembly ramp, and then propels the final column with the assembled columns together across the ramp to the loading zone as the pusher advances to its remote extended position.

Abstract: An improved power supply capable of driving an external device at relatively high power levels for intermittent periods of time with the power supply driven by relatively low current input power which can vary widely in voltage. The power supply incorporates a step-up switching voltage converter module for increasing the input voltage to a higher value so as to charge an energy storage capacitor to an energy level sufficient to power the external device for said intermittent periods of time at relatively high current. The energy storage device voltage output is regulated by a step-down switching voltage converter module. Control signals sensing the voltage of the energy storage capacitor can be used to control energization and de-energization of the external device.

Abstract: A communication method and system for determining the transmission speed of a communicating remote unit with respect to a host communicator. The communication method uses a start of message header containing a known number of timing intervals, called ticks, with the header transmission in a logic one or a logic zero state. A start of message header is detected by the host communicator and its logic one state is sampled after a given period of time in order to determine its actual logic one duration. From this, the actual tick time is determined so as to be able to determine data "1" bits and data "0" bits from the remote unit by sampling the incoming data at precise intervals of time so as to properly determine the data bit states. A logic zero to logic one state transition at the start of each data bit is used to reset the communicator tick timer.

Abstract: A selective collector of a human patient's saliva for monitoring or analysis is formed as a substantially conical flat concave cup of resilient molded polymer with tubing connections at an apex portal, and a large entrance portal having a soft compliant foam elastomer rim positioned for contact with the patient's soft tissue, such as the interior of the patient's cheek around the parotid salivary duct.Suction is connected to the soft foam rim, holding the concave cup in position, and suction, fixed pressure, pulsing pressure or electrical stimulation may promote the flow of saliva to a collector vessel. Medication may be administered to the patient's soft tissue if desired throug the entrance portal.

Abstract: An apparatus for propelling a plurality of pipes arranged in series comprises basic thrusting means for generating a thrust to be applied to the pipes and intermediate thrusting means for receiving the thrust from the basic thrusting means and applying the received thrust to one of the pipes. The intermediate thrusting means includes a press head provided with a portion displaceable to a position where the portion is capable of abutting against the rear end face of one of the pipes when the intermediate thrusting means is advanced while displaceable to another position where the portion does not interfere with the advance of the following pipes when the intermediate thrusting means is removed and an intermediate body extending rearward from the press head such as to receive the thrust from the basic thrusting means and apply the received thrust to the press head.

Abstract: In a septic system for handling household waste water, used vehicle tires are employed to form the septic tank and the leaching galleries. Vehicle tires sealed to one another and in combination with end caps provide a watertight and lighttight enclosure in the septic tank. An inlet conduit permits the influx of sewage into the enclosure while an outlet conduit allows egress of effluent from the enclosure via hydrostatic pressure. The drain field used with the system and also useful for other purpose has tires axially aligned forming an array with each tire defining an interior hollow chamber. A delivery conduit leading from the outlet conduit of the septic tank introduces effluent into the hollow chambers of the vehicle tires where it is allowed to seep therefrom into the surrounding earth through apertures in the walls of the tires. The tires in the drain field can be horizontally aligned or can be in a vertical stacking arrangement similar to the arrangement found in the septic tank.
