Abstract: An elongated frame made up of rails, and having a main endless belt conveyor for carrying parts of sandwiches, and completed sandwiches through the machine. A slicer carriage is mounted on and above the frame, having an endless slicer belt means parallel with the main belt for gripping the sandwiches between the belts for conveying them. The slicer belt means is made up of transversely spaced belts, forming a space therebetween, and a slicer blade is operable in the space between the belts. The main belt has a longitudinal groove in its outer surface, to receive the edge of the blade to enable the blade to cut entirely through the sandwiches and in slicing them. The slicing carriage, and the slicer blade, each individually, are vertically adjustable for accommodating sandwiches of different thickness.

Abstract: A casing having an arcuate tool bit at its front end. The tool bit oscillates, having opposite points entering into the bone alternately. The tool bit is driven by a rocking lever, and the lever is driven by a hammer driven by a motor with a flywheel. The arrangement provides a percussion thrust against the lever by the hammer in each of opposite directions.

Abstract: A tray is positioned in the car trunk, mounted on extendible links, and movable from a lower position on the floor of the trunk to an upper position at the open top of the trunk. In the preferred form it is driven by the battery of the car, but as an alternate, may be hand powered. The tray has a tail gate that can be opened facilitating putting articles in and removing them from the tray. An alternate form includes a basket mounted on a platform and is extendable rearwardly out of the trunk when it is in its upper position.

Abstract: Four post units in a positional pattern on which the patient lies, in a surgery operation. The post units are supported on a table, and have recesses in their under surface forming vacuum chambers with the table top. Hoses lead from the vacuum chambers to a vacuum source, and valve means individually control the hoses. The post units are thus locked in place by vacuum, and each can be released individually to enable it to be adjustably moved on the table top to enable better positioning for engagement by the patient.

Abstract: The invention provides a uni-flex belt which can bend only in one direction and which has particular utility in treadmills. The uni-flex belt of the invention comprises a continuous loop having an outer portion and a non-stretchable inner portion attached to one another. The outer portion comprises a multiplicity of abutting transverse rigid tread segments which extend across the belt and which have sides substantially parallel to one another. The tread segments press together and are laterally compacted during operation of the belt to provide a substantially smooth outer surface and to cooperate with the inner portion to prevent the belt from sagging or bending in the other direction.

Abstract: A method and apparatus for collection of fecal matter designed to operate efficiently in a zero gravity environment. The system comprises a waste collection area within a body having a seat opening. Low pressure within the waste collection area directs fecal matter away from the user's buttocks and prevents the escape of undesirable gases. The user actuates a piston covered with an absorbent pad that sweeps through the waste collection area to collect fecal matter, scrub the waste collector area, press the waste against an end of the waste collection area and retracts, leaving the used pad. Multiple pads are provided on the piston to accommodate multiple uses of the system. Also a valve allows air to be drawn through the body, which valve will not be plugged with fecal matter. A sheet feeder feeds fresh sheets of absorbent pad to a face of the piston with each actuation.

Abstract: A highly compact and lightweight exercise machine which, in one unit, includes the features of a bicycle ergometer and of a rope pulling machine. The resistance to the movement of the bicycle ergometer and rope pulling machine features is provided by the same resistance apparatus. The resistance apparatus includes a metallic disk which is connected to the bicycle ergometer and rope pulling features and which rotates near a source of magnetism. The interaction between the rotating disk and the source of magnetism creates electromagnetic forces which exert drag on the disk. The exercise machine is constructed so that all rotatable components require only two shafts, which construction significantly reduces the space requirements of the exercise machine components. A differential pulley system is incorporated in the exercise machine and amplifies the resistance produced by the resistance apparatus.

Abstract: The device of this invention comprises a drum 11 rotatably mounted on a mounting frame 10. The device is designed to receive articles to be sorted from a controlled feed conveyor 12. The rotating drum 11, through its internal structure including lift fins 16 and associate structure, position the oblong articles on counter-rotating shaft conveyor 13. The articles proceed down the counter-rotating shaft conveyor 13 to a chain link loading mechanism 36 placing the sorted articles in receiving slots on chain link conveyor 37. Incorporated in the invention of this device are control structures such as feed control tilt flaps 20 and their associated structure which controls the rate of supply of articles to the rotating drum 11 by feed conveyor 12 and return rejected articles to the rear of the drum. A detector 29 is incorporated in association with the counter-rotating shaft conveyor 13 and include shaft conveyor light source 30, the shaft conveyor electric eye 31, and clearing means 32.

Abstract: A conveyor feeder for positioning and loading candy eggs on a chain link conveyor. The feeder receives candy eggs from a controlled feed chute, a cone member distributes the eggs radially in a cylindrical hopper onto a counter-rotating ring. Rotating brushes assist in positioning the eggs in the circular receptacles in the ring. A conveyor chute facilitates the dropping of the eggs onto the chain link conveyor having spaced separating pins defining compartments for receiving a single candy egg. The conveyor feeder is suitable for positioning candy eggs on a chain link conveyor feeding automatic wrapping machine.

Abstract: The present apparatus shows a device for measuring the total volume displaced by a human body. A tank portion has an enlarged upper opening for an individual to enter the tank therethrough. Thereafter, while the individual is in a sitting position inside of the tank, the enlarged upper opening is closed with the individual's head extending upward into an open ended cylinder. A tall cylinder of equal diameter with the open ended cylinder is connected to a control console which pumps the water level inside of the tank up to a predetermined point inside of the open ended cylinder. Thereafter, if the individual lowers his head below the water level by releasing a seat on which the individual is sitting, an accurate reading of the column of water displaced can be obtained on a manometer and compared with a prior reading before entering the tank.
