Abstract: A method of vacuum packaging compressible material in a sealed flexible fluid impervious container, such as a poly bag, is disclosed. One or more slits are made in the container and air in the container is withdrawn through the slits. This creates a partial vacuum in the container that results in compression of the compressible material. When the desired compression has been obtained, restraining means are placed around the flexible container to maintain the package in a compressed state when the partial vacuum is eventually lost. A novel apparatus for use in this method is also disclosed.

Abstract: A substantially closed cylinder containing a compressible fluid, such as air, and a free piston for reciprocation within the cylinder, and a number of elongated passageways, each having an end opening into the cylinder and an opposite closed end. The passageways are heated along their lengths. The fin-shaped open end portions and the cylinder wall are cooled. Piston reciprocation is effected by the force of heated expanding gas moving from the closed ends of the passageways to drive the piston in one direction as the gas cools in the region between the piston end and the cooled open ends of the passageways. The piston compresses the gas at the opposite piston face, which gas in turn drives the piston back after the force of the compressed gas exceeds the force of the cooling gas to regularly repeat such cycle.

Abstract: Two battery-powered hand-held programmable calculators for performing arithmetic, trigonometric and logarithmic functions and displaying the results thereof are provided with the capability of being fully programmable via magnetic cards or a keyboard. Through a unique transmographic coding scheme, programs coded on one embodiment may be executed on a second embodiment even though the key codes for the respective functions are dissimilar. In one embodiment, a processor distinguishes between magnetic cards containing coded instructions and cards containing data. The calculator prompts the user via the display when additional cards are needed to form a complete set of program instructions. The processor, registers, and display may be initialized by control words on magnetic cards. During program execution, the calculator can pause to permit data entry from the keyboard or from magnetic cards. The operator may also cause the calculator to pause and display the data of an intermediate calculation.

Abstract: In a tack seat lasting machine the wipers are moved lenthwise of the shoe and inwardly thereof under the action of a single piston-and-cylinder arrangement. For setting the appropriate "nail pattern", the action of said piston-and-cylinder arrangement is terminated by adjustable stroke limiting means, comprising a valve actuated by an abutment, the valve moving with the wipers and the abutment being adjustably positioned in the path of the valve. A further abutment, spaced from the first-mentioned abutment, controls the rest position of the wipers. The wipers are arranged symmetrically centrally of the machine, and the heel band is capable of clamping a shoe in the position in which it is presented by the operator, thereby avoiding the need to adjust the wiper for lefts and rights.

Abstract: An improved automatic sponge mop with an airtight hollow handle containing a piston which when pulled backwards by the user creates a vacuum in an air chamber. The air chamber has a diaphragm sealing the bottom of it which will move upward in response to the vacuum pulling with it the bottom of a hinged box which folds in upon itself and in so doing compresses an affixed sponge. After the sponge is wrung out the user simply pushes the piston downwards and the process is reversed, opening the sponge to its original cleaning position. The sponge is held in place by dovetail fasteners which allow easy removal by simply pulling sideways on the sponge until it slides off the wringer. Similarly, replacement is accomplished by engaging the tongue and groove connection and pushing the sponge back on. Sliding and accidental removal are inhibited because the sponge is always under tension from the springlike walls of the wringer.
