Abstract: A variable resistance exercising device is described for executing isometric, isotonic and isokinetic exercises. The device includes a unitary, open-ended mandrel or bar which is shaped to define at least one shaft which is adapted to receive several turns of rope thereon, an open support loop for the rope situated near one end of the shaft, and an open guide loop at the other end of the shaft for holding the rope in proper engagement with the shaft. By virtue of the mandrel's open-ended construction, the rope may be easily engaged or disengaged from the device, and the resistance provided by the device may be changed quickly.

Abstract: A method and chemical solutions for use in increasing the surface and volume conductivities of a cellophane substrate. The substrate can be used for dielectric copying or any other purpose for which a through-conductive substrate is required.

Abstract: A process for allowing non-programmers to generate customized formats for computer printouts according to user specifications. The process allows a user to create a report or other formatted representation of data by responding to a sequence of prompting stimuli. Each stimulus is presented to the user by a computer processor in combination with a menu of command choices or in combination with instructions for responding by alphanumeric command or designation. The sequence of prompting stimuli is dependent on previous command choices to present only relevant stimuli to the user. A list of generic default format commands specifies parameters not specified by the user. Consequently, the user needs to respond only to a few stimuli in order to generate a completely formatted representation of data.

Abstract: A chemical solution to be applied to a substrate either as a surface coating or as an impregnating solution which, in both cases, increases the conductivity and in the case of impregnation also increases the dimensional stability of the substrate. The solution consists of nitrocellulose and a quaternary ammonium compound both dissolved in ethylene glycol monomethyl ether or, alternatively, methyl alcohol. The porous substrates such as paper, vellum and permeable materials like cellophane may be impregnated with the solution. Both the porous and permeable substrates and non-porous substrates, such as polyester films, may utilize the benefits of this solution as a face, back or intermediate conductive surface coating. The chemical solution can also be kneaded in film compounds before casting to reduce film resistivity.

Abstract: A conductive coating structure useful in dielectric recording media and other uses comprises nitrocellulose. In one embodiment, conductive pigments are added to the nitrocellulose thus increasing the opacity of the substrate, and providing a surface suitable for handwritten annotations.
