Abstract: A chiropractic table has a power-operated linkage that will simultaneously tilt the table as it is lowered from an elevated position and also return the table to a horizontal position as it is elevated. The table employs a modified, movable parallelogram type of linkage, as opposed to a scissors-type linkage, which when combined with an open center frame allows the table to be lowered to a height not attainable with the prior art tables. A patient footplate assembly includes additional linkage and is operated by the tilt actuator so that when the table is elevated, the footplate is rotated out of the way, and when the table is tilted and lowered, the footplate will be rotated upwardly into position so that the patient can easily step off the table.

Abstract: A seal assembly primarily for recreational vehicles that have an expandable room. The seal assembly seals the opening in a fixed wall of the vehicle through which the expandable room extends. The seal assembly includes a retainer that is attached to a fixed wall of the vehicles, the retainer holding a bulb-type seal properly in place. The retainer securely holds the bulb seal in place until it is compressed by the expandable room, and the retainer further functions to prevent the bulb seal from being crushed which could cause premature failure of the seal. The seal assembly also provides for relative movement in different directions between the meeting surfaces of the fixed room and moveable room. In this way, it acts as a low friction bearing surface while still maintaining a complete and positive seal at all times.

Abstract: A method of overcoming the problems of measuring the exhaust flow from a vehicle engine, which flow is pulsating and reversing, making it difficult to accurately measure. An amount of flow is added to the exhaust flow so that the combined amount of flow exceeds the reversals, and therefore the flow through the primary measuring device is raised a sufficient amount so that the measured flow of the exhaust is always positive. The source of the added flow can be by diverting some of the exhaust flow itself downstream from the measurement device and reintroducing it upstream of the measurement device. In the alternative, the added flow can be from a source external to the exhaust flow.

Abstract: A bucket elevator conveyor system of the straight horizontal, “C” and “Z” configurations. In these bucket elevator conveyor systems, loading of the buckets can occur anywhere along the horizontal run adjacent the take-up end and discharge of the buckets can be made at the drive area or along the bottom run of the upper horizontal sections of the “Z” and “C” configuration. This provides not only for discharge of the product from the buckets traveling along the lower path of the conveyor, but also provides for simple, intermediate discharge. In addition, there are provided relapping mechanisms to assure proper relapping of the buckets, This is accomplished by reason of a unique bucket design having a cam on one end combined with the front and rear flanges angled to assure proper operation and lapping of the buckets.

Abstract: A system for supplying heated milk or other liquids to individual drinkers from which animals, particularly baby pigs, can drink on a need basis by actuating a valve in the drinker that allows the milk to flow into the drinker. The system has a plurality of drinkers within a closed system in which the milk is supplied from a reservoir, heated to a minimum predetermined temperature range and pumped to each drinker which is positioned so that milk is continuously circulated through the drinker any time the circulating pump is running. This not only keeps the heated milk from spoiling, but it also prevents the drinkers from becoming clogged and permits the entire system to be cleaned in place.

Abstract: A push-pull drive chain mechanism and scissors linkage assembly and lifter assembly all powered by hydraulic cylinders to affect the coordinated, linear movement of an expandable room in a recreational vehicle. The drive chain moves generally vertically along a first structural member, such as a vehicle frame member, and then horizontally as the hydraulic cylinders extend or retract to move the expandable room relative to the vehicle frame. The lifter assembly assists in raising and lowering the expandable room so that when the room is extended, the floor of the expandable room will be substantially flush with the floor of the vehicle.

Abstract: A system for extending and retracting expandable rooms in vehicles. The system employs linear actuators that can be mounted laterally to the direction of movement of the room when it is expanded or extended. In order to provide for extending and retracting the room, the actuators are connected to heavy chains which are connected to the main body of the vehicle structure and which will flex in one direction only. The chains ride in tracks such that when the actuators are retracted, the room will be extended, and when the actuators are extended, the room will be retracted. The system includes infrared sensors that sense movement of each chain to produce a signal that is used to synchronize movement of all of the actuators as the room is extended or retracted.
