Abstract: A non-spinning projectile that is self-guided to a laser designated target and is configured to be fired from a small caliber smooth bore gun barrel has an optical sensor mounted in the nose of the projectile, a counterbalancing mass portion near the fore end of the projectile and a hollow tapered body mounted aft of the counterbalancing mass. Stabilizing strakes are mounted to and extend outward from the tapered body with control fins located at the aft end of the strakes. Guidance and control electronics and electromagnetic actuators for operating the control fins are located within the tapered body section. Output from the optical sensor is processed by the guidance and control electronics to produce command signals for the electromagnetic actuators. A guidance control algorithm incorporating non-proportional, “bang-bang” control is used to steer the projectile to the target.

Abstract: Continuous paper sorter mechanism in which a receiver section is comprised of at least two columns of inclined side-by-side stacks of paper storage bins or shelves with entrances for receiving paper sheets from the feeder. The receiver is mounted for lateral movement relative to a feeder mechanism, such that the bin entrances move past the feeder in a generally vertical plane. The feeder has an in-feed conveyor which takes paper from a copy making device such as a press or duplicating machine and feeds the sheets of paper either to an intermediate downwardly inclined conveyor or onto an intermediate upwardly inclined conveyor, depending on whether the feeder is distributing paper sheets from the top or from the bottom. Sheets from the intermediate conveyors in turn are transported to a generally vertically disposed, reversible feeder conveyor.

Abstract: An apparatus for generating electrical pulses which are suitable for application to selected areas of the user's body for pain control or muscle stimulation. The current level, pulse width, pulse rate, voltage level and pulse configuration are all controlled to produce the desired effects. The apparatus includes a timing circuit which emits pulses of selected width and repetition rate. The pulses from the timing circuit energize a switching circuit which selectively connects the primary of a pulse transformer to a power source. The transformer is so constructed and arranged that it operates near saturation, thereby effectively operating as a current limiter, which helps to prevent spikes in the electrical pulse output of the apparatus.

Abstract: An electrode which is adapted to be used on a human body and suited for transmitting electrical impulses into the body. The electrode is relatively thin in cross-section and comprises in succession a lower layer of electrically conducting rubber, an intermediate layer of electrically conducting mesh or screen, and an upper layer of non-conducting rubber. An electrically conducting snap fastener is embedded in the electrode and is in electrical contact with the screen. The metal fastener provides a terminal connection for a conventional electrical lead, which carries the electrical impulses from a source thereof to the electrode.

Abstract: Sorting and collating apparatus for use with copying and duplicating machinery for distribution of flexible sheet material to designated stations or series of stations. The device has an interface unit for accepting paper sheet copies and which selectively diverts said copies into a tray or to the base of the sorter tower. From the base the copies are either directed into the sorter tower to a designated bin or they are sent on to the next sorter tower module. The apparatus employs mass air movement type conveyors for paper transport. Means are provided for selectively diverting paper copies into designated paper receiving bins, and means may also be provided for maintaining the papers in aligned relationship in the individual paper receiving stations.
