Abstract: A self-powered life monitor in a pocket-size, portable container including a casing with electrode probes mounted on the casing which are capable of piercing the skin to rest in subcutaneous tissue. The monitor further includes an amplifier electrically connected to the electrode probes and to a "life" indicator. The monitor is used by placing the electrode probes at different positions in an area of the human body where electrical potential is indicative of life activity, such as the areas of the heart or brain. The amplifiers enhance the difference between the electrical potentials measured by the probes, and the indicator indicates the existence and strength of the electrical potential and hence the presence or absence of life. For brain activity detection, a first embodiment (note particularly FIGS. 2 and 7) has supplemental, swing-out, pivoting electrodes, while a second embodiment (FIGS. 8 and 9) has supplemental, spring-out electrodes.

Abstract: A crossword puzzle system for creating crossword puzzles including the steps of (a) obtaining a crossword puzzle grid defining sections; (b) inserting "generator" words into the grid; (c) making "possibility" check from a provided "Table of Average Preference Values"; (d) assigning "C" (consonant) and "V" (vowel) locations based on highest frequency rate with the longest words done first and with "possibility" checks done as needed; (e) determining the relative priorities of the crossword puzzle grid sections; and (f) filling in the blanks with the use of provided "Paralog" lists starting with the most difficult.

Abstract: An ink pen is provided which is comprised of an outer rotating and sliding body which fits comfortably, overriding an inner ink containing cartridge. The outer body slides with respect to the inner cartridge when rotated with respect thereto. Rotation of the outer body with respect to the inner cartridge causes the cartridge to retract within the outer body, thus protecting the pocket of an individual upon placement of the pen in such a position when the pen is not in use. Inadvertent placement of the ink pen into a shirt pocket, for example, when the pen is in the writing position, is prevented by means of a projecting clip guard which catches on the outer portion of the pocket, thus preventing the pen from entry into the pocket when it is in its writing position.

Abstract: There is disclosed a new and improved air-fuel metering regulator which provides for extremely fine adjustment of the flow of fuel to the internal combustion engine which may be operating under idling, cruising or various accelerating power circumstances. This is provided, in the preferred embodiment, by the novel arrangement of the separate air and fuel diaphragm and chambers with extremely fine adjustments being provided in both the air or vacuum chamber bodies and the fuel chamber bodies to limit the travel of both diaphragm assemblies in their respective linear directions toward or away from the vacuum or fuel chamber bodies. As a result of the fine adjustments possible and the particular layout of the chambers, more precise and upgraded performance is available in the internal combustion engine as a result of the fuel supply to the internal combustion engine being made more responsive to the various operating conditions of the engine.

Abstract: A percussion instrument provides a plurality of substantially horizontally disposed hollow tubes having rattle elements therein. A handle providing a gripping surface connects the tubes and the connection orients the tubes in a substantially parallel orientation towards one another. In the preferred embodiment, the handle is comprised of two substantially vertical tubular members attached to the upper hollow tube, there being two substantially horizontal arms attached to the bottom portion of the vertical tubes, with the second hollow tube being attached at substantially right angles to the lower arms.

Abstract: An automatic and semiautomatic small caliber conversion system for automatic or semiautomatic shotguns and rifles such as, for example, M-16 and AR-16 rifles, including a uniquely designed three element structure and associated ammunition feeding means to permit the use of smaller caliber, inexpensive ammunition in rifles and shotguns designed originally for larger caliber ammunition. The system includes a bolt/receiver assembly which easily replaces the bolt carrier of the, for example, M-16 rifle, and a magazine assembly which can be inserted by hand into any standard, for example, 0.223 round M-16 magazine. The bolt/receiver assembly is made up of three sub-assemblies, a receiver, a bolt, and a recoil spring. The receiver sub-assembly includes a section of a circle with a short barrel section in the front which fits into the M-16 chambers, a receiver lug at top rear to locate it within the M-16 chamber and prevent its rotary or linear motions and a guide rail.
