A pen-based circulator recognizes handwritten input. The calculator comprises a display simulating a sheet of paper, and a stylus simulating a pen. The user writes a calculation on the calculator as if it were a piece of scratch paper. The calculator uses handwriting recognition to identify the various elements of the calculation, performs the calculation, and then displays the result at an appropriate location.

A pen-based teaching system recognizes handwritten input. The system comprises a display simulating a sheet of paper, and a stylus simulating a pen. The system uses handwriting recognition to interact with the student, so that the student enters input into the system as though it were a piece of scratch paper.

A syringe assembly comprises an elongated tubular syringe barrel having a tubular needled mounted to one end and a plunger slidably disposed within the barrel. A hollow outer casing is mounted to and surrounds the syringe barrel with the barrel and the casing defining an interior space therebetween. A tubular sleeve is telescopically disposed within the space between the casing and barrel and is movable between an extended position surrounding and shielding the syringe needle and a retracted position in which the needle is exposed for use. A longitudinal slot is formed in the casing and a projection mounted to the sleeve is slidably disposed within the slot to function as a lever for moving the sleeve between its extended and retracted positions. Notches are formed on either end of the slot such that the projection can be moved laterally into a notch to lock the sleeve in either its extended or its retracted position.

A cryogenic food product freezing tunnel comprising a stationary structure including an entrance end housing section, a tunnel housing cover, and an exit end housing section, a conveyor to transport food products through the tunnel housing, a spray header to spray a liquid cryogen onto the food products near the exit end of the tunnel, and an exhaust plenum to exhaust cryogen gas from the entrance end. The base of the tunnel housing is a series of U-shaped modular units arranged end-to-end and suspended from the stationary structure by individual hydraulic elevators, movable between a lowered, open service position and a raised position sealed against the housing cover and the end housing sections. Each end base unit is lowered outwardly and downwardly to its service position and is raised along the same path; the base units are lowered in predetermined sequence, end units before center units, and are raised in the reverse sequence. The base units are held sealed to the stationary structure by constant pressure applied by the elevators, using double-bulb silicone gaskets with bonded polyfluoroethylene coverings. Each base unit includes plural sub-modules joined by shielded external expansion slip joints with a continuous interior sheet metal covering. The cover is of modular construction with polyfluoroethylene coated silicone gaskets of clothes-pin configuration between modules. The spray header is a large tube with liquid discharge nozzles below and gas relief nozzles above; excess liquid cryogen is collected in a very long pan below the header and the upper run of the conveyor belt is guided down and up very mild inclines to skim the surface of liquid cryogen in the pan. Insulated doors on the ends of the tunnel and an automatically controlled exhaust damper permits standby for extended periods. The conveyor belt supports are also of sub-modular construction.

A cryogenic expansion engine includes intake and exhaust poppet valves each controlled by a cam having adjustable dwell, the valve seats for the valves being threaded inserts in the valve block. Each cam includes a cam base and a ring-shaped cam insert disposed at an exterior corner of the cam base, the cam base and cam insert being generally circular but including an enlarged cam dwell, the circumferential configuration of the cam base and cam dwell being identical, the cam insert being rotatable with respect to the cam base.
