Abstract: An ignition system for use with spark ignited engines wherein the ignition system is compact and mounted beneath the associated flywheel. The ignition system includes a manually actuated timing ring for manually advancing the firing point, and includes a rotor essentially in the form of a spiral having a discrete discontinuity on its periphery for providing enhanced safety features.

Abstract: An apparatus for removing undesirable particles, such as metal and fiberglass, and harmful chemical forms, such as acid etchants, from a fluid solution having container means at least partially formed from a plastic electret material disposed in contacting relationship with the solution and carrying an electrostatic charge which causes the particles in the solution to adhere to the surface of the container formed from the material. The container means include a receiving tank having baffles spaced therealong, a filter assembly having filter cartridges to remove foreign matter from the solution and a holding tank, each of the tanks and the shell of the filter being formed from the plastic electret material. The holding tank includes a metal chip assembly placed in contact with the solution and chemically reactive with etchants in the solution to neutralize them.

Abstract: An electronic ignition control system including one coil assembly having a high number of turns to charge the associated capacitors to a desired level when the speed of the engine is low, and another coil assembly having a low number of turns to charge the capacitors to a desired level when the speed of the engine is high to thereby provide energy at a suitable level to fire the associated spark plugs. The system also includes means for regulating the voltage supplied by the alternator coils to a battery and thus preventing the battery from overcharging; and, means are provided for driving a tachometer proportionally to the firing pulses supplied to the spark plugs.

Abstract: A solid state starter to selectively accelerate X-ray tube rotors to the low speed utilized for fluoroscopic examinations and up to the high speed required for spot-film or radiographic exposure operation, and wherein the speeds of the rotor may be varied throughout the speed range.

Abstract: A closed loop system is disclosed for monitoring and regulating the power applied to the stator of an induction motor for controlling the operation of the rotating anode of an X-ray tube in order to insure acceleration of the rotor to a selected speed of rotation, to maintain the selected speed of rotation, and to provide a braking voltage to the rotor as desired. The system provides direct inter-related operation of an anode rotor, an anode rotor rotation sensing detector, and an X-ray generator.

Abstract: A curved tine terminal for inserting or snapping into a mounted position on a printed circuit board or other supporting surface to be securely retained therein, with the terminal being adapted to receive a plurality of electrical leads and having tines arcuate both along their length and in their cross-section, and serrations in the terminal wall opposite the tines for engaging and securely holding the leads in the terminal in conjunction with the tines.

Abstract: A self-mountable, self-contained and encapsulated rectifier assembly operative to provide a high D.C. voltage at low current while minimizing arcing, corona and other disruptive electrical phenomena.

Abstract: The present disclosure pertains to a novel score-line construction for easy-opening pull tab type cans, as well as a method for forming said score-line. In this regard, the score-line is disposed closely adjacent to the rim of the container end portion, and includes a substantially perpendicular outer peripheral wall. This arrangement provides, upon formation, a zone of compacted material immediately below the base wall surface of said score-line, which zone has an outer peripheral edge that terminates abruptly and substantially in alignment with the aforementioned perpendicular outer wall surface. Accordingly, upon opening, the path of fracture will follow said outer peripheral wall and be substantially coextensive with the edge of said zone, precluding erratic fracturing of said score-line and the formation of relatively sharp burrs.

Abstract: A disposable container for the storage of foodstuffs having inedible parts or wrappers, whereby the container is divided into two separate compartments, each compartment having perforations for the forming of an opening therein. The opening in one of the compartments serves as an access point for the foodstuffs contained within, and the hole in the other compartment serves to allow the entrance of the inedible portions and/or wrappings of the foodstuffs into the second compartment for disposal.

Abstract: An apparatus for sensing the speed of a rotating anode of an X-ray tube and for providing signals responsive to the detected rotating speed.

Abstract: A device utilizing thermal and electrical energy for cooking food in a minimal time, particularly pieces of food in a flat configuration such as meat patties or hamburgers, steaks, and bacon.

Abstract: High voltage grounding strap including a terminal member with a plurality of resilient tines for providing electrical contact such as to the external Aquadag coating on a picture tube, a receptacle connector formed in the shape of an elongated flattened cylinder and having a flared open end for allowing easy insertion of a corresponding male connector formed on the terminal member. The grounding strap including a plastic sheath extending up to and covering said receptacle connector to minimize corona and arcing and the receptacle connector includes a locking means on its interior surface.

Abstract: An electrical terminal connector for inserting or snapping into a mounted position on a printed circuit board to be securely retained therein, with the connector being adapted to receive a plurality of electrical leads and having tines or leads for engaging and securely holding the leads in the connector.

Abstract: An electroacoustical transducer of the magnetic armature type having an efficient electromagnetic configuration with the armature being formed integrally with a support yoke. The yoke includes a base from which two arms extend generally parallel to the armature, the two arms engage pole pieces formed of laminations, and the vibrating end of the armature is positioned in the plane of the diaphragm and is connected thereto. The armature may include a boss or gusset adjacent to the contilever end of the armature to stiffen it and thereby raise the resonant frequency of the transducer. A casing is included which is spaced from the yoke and serves as a magnetic shield.

Abstract: A chopper assembly or shutter apparatus is disclosed for X-ray machines for controlling a chopper or shutter for selectively exposing the areas of a patient's body for obtaining X-ray photographs.
