Abstract: ABSTRACT OF THE DISCLOSURE          A capacitor is connected across a pair of breaker points to reduce electric arcing as the breaker points are opened and closed in association with the operation of an internal combustion engine.  One of the breaker points is carried on a breaker lever supported on a pivot post formed integrally with a breaker plate having an abutment supporting the other breaker point. and the breaker points are urged to-gether by an electrically conductive spring connected between the movable breaker point and another  butment formed on the breaker plate.  The pivot post is provided with additional support by a bridge member secured to the abutments of the breaker plate which is also formed with a receptacle opening externally on an upper or lower side for receiving an uncanned capacitor having uninsulated leads.  m e capacitor is sealed with epoxy resin in the receptacle of the breaker plate which is constructed from an electrically and thermally insulating material. while the leads are secured in the slots in the ad-jacent surface by heat deformable tabs.  The spring is con-nected to one of the capacitor leads while the stationary breaker point is connected to the other capacitor lead and grounded to the engine by an exposed portion of the lead which is pressed against the engine or contacted by a screw securing the breaker plate to the engine.  Alternatively. the capacitor is connected to the breaker points by conductor straps or plated sections on the breaker plate.

Abstract: Abstract of the Disclosure A  rechargeable infusate pump for implantation in the human body can be refilled periodically by injection through an inlet septum under the skin.  A conduit from the pump outlet conducts fluid to an infusion site in the body.  The needle penetrating the septum protrudes into an antechamber and discharges fluid and any foreign matter is trapped in the antechamber so that it cannot enter the pump chamber and possibly clog the pump outlet.  This foreign material is removed by injecting a needle into the antechamber and drawing a vacuum to suck out the debris.  The pump also has a special ring-like outlet filter in the fluid stream between the pump chamber and its outlet to provide a maximum amount of filter area in a minimum amount of space and the pump outlet includes a special flow controller which is able to very accurately meter the infusate to the selected body site.

Abstract: ABSTRACT OF THE DISCLOSURE       A large area visual display matrix of ultra-violet initiated individual small gas discharge elements.  Each element remains in a discharge condition until the voltage applied to a common anode is turned off and for this reason the matrix requires no associated memory or storage property to remain on as long as information is to be displayed.        The matrix generally comprises, in order, an electrically conductive cathode with a low work function material photo-emissive coated thereon which emits electrons when irradiated by U.V. light, an insulating medium with apertures therein, individual anodes with holes therein the holes being axially aligned with the apertures in the insulating medium, a voltage supply for each anode, the foregoing elements being sandwiched between a base and a U.V. permeable cover, and a suitable gas filling for the apertures.  A source of U.V. light is directed at that portion of the visual display it is desired to illuminate.

Abstract: ABSTRACT OF THE DISCLOSURE           A touch control switch circuit operable by a hum pickup signal induced in a human body by a power supply line incorporates a compensation arrangement to eliminate false operation of the circuit by fluctuations in the power supply signal.  The circuit comprises a touch receptor operable by electrical contact with the human body to receive the induced hum pickup signal, a touch detector responsive to the hum pickup signal received by the touch receptor for producing an output signal in response to a change in amplitude of the hum pickup signal, and a compensation circuit responsive to the power supply signal for controlling operation of the touch detector to prevent a false output signal in response to fluctuations in the power supply signal.  The compensation arrangement may be embodied as a reference detector which provides a variable reference signal for the touch detector to compensate for power line fluctuations or which disables the touch detector output upon the occurrence of power line fluctuations.
