  • Patent number: 4394639
    Abstract: A circuit fuse assembly comprising a plurality of fuse elements which are simultaneously formed using printed circuit or through hole plating techniques and including means for easily substituting a different one of the plural fuse elements when the in-circuit fuse element burns out due to an overload current condition. In the preferred embodiment, the fuse assembly is (a) integrally formed with the printed circuit of the fused electrical apparatus and (b) formed with a common electrical connection such that a single electrical bridge of solder or other means enables substitution of a replacement fuse element. Other embodiments of the present invention provide a restorable printed circuit fuse for use in standard fuse holders, in-line plug connectors, conventional three prong plug connectors, edison bases, and plug-in triple outlets.

  • Patent number: 4295793
    Abstract: An electronic controller maintains the level of fluid in a container between an upper level and a lower level defined by the location of two probes in the container. Each probe actuates a first light source-photosensor pair used for controlling a device capable of changing the fluid level in the container. In some embodiments of this invention, a second photosensor-light source pair latches the first pair to provide system hysteresis. In other embodiments, the same pair both controls the fluid level device and latches itself to provide system hysteresis.

  • Patent number: 4152784
    Abstract: A fabric garment which automatically removes unwanted hair while being worn against the skin of the user. The garment is coated with a pressure sensitive microencapsulated depilatory agent. Pressure exerted by a hair stubble against the fabric causes the microencapsulation to rupture and dispense the depilatory agent in a small localized area around the hair follicle. The depilatory agent dissolves the hair stubble without irritating the user's skin.

  • Patent number: 4144555
    Abstract: A combination of a potentiometer and an integrated circuit module are mounted on a printed circuit board which interconnects these members and provides for external connections. Mechanical mounting of the printed circuit board, the potentiometer, and the integrated circuit module is provided by a single mounting bushing of the potentiometer. The mounting arrangement also permits a heat sink tab on the integrated circuit to be clamped by this mounting bushing directly against the front panel of a user's equipment. Thus, the single mechanical mounting connection for the combination at the potentiometer bushing not only mechanically mounts all of the elements but additionally provides a heat sink connection for the circuit. At the same time, the use of the printed circuit board in this combination permits automated assembly and soldering which substantially reduces the cost of the circuit.

  • Patent number: 4112312
    Abstract: A solid state fluid sensitive switching member which utilizes fluid contained in a cavity to conduct the heat generated during high current switching operations away from the temperature-sensitive solid state elements of the switching member. A heat sinc tab thermally connected to the solids state elements is positioned in the cavity where the presence or absence of a fluid is to be monitored. When fluid is present in this cavity, the solid state elements which produce heat are in a closed circuit configuration and the heat sinc tab directly conducts heat from the heat-producing solid state members into the fluid being monitored. When no fluid is present in the monitored fluid cavity, the heat sinc potentials of such fluid are absent. However, in this configuration the solid state circuit elements are in an open circuit configuration and do not produce substantial amounts of heat, so that no heat sinc is required.
