Feed-through capacitor of the type for use in filters and the like and including discoidal ceramic capacitors arranged in stacked relationship and electrically connected in series. Series arrangement of the discoidal capacitors prevents shorting through the feed-through capacitor in the event of failure of one of the discoidal capacitors therein and results in substantially improved insertion loss characteristics when compared to feedthrough capacitors having a single discoidal capacitor.

A flow through converter utilizing a transistor as the switching element with its collector emitter path connected in parallel with a capacitor and a transformer which is arranged in the power circuit and the output winding which is connected to a rectifier diode in the series arm and to a free diode in the shunt arm and with a second switching transistor connected in parallel with the adjusting transistors so as to prevent overload on the first transistor.

The specification discloses a prefabricated factory built fireplace for on site installation with a dual opening hearth. The fireplace has a firebox disposed over the hearth which is formed of two upstanding sidewalls with front and rear panels disposed therebetween. Each panel defines a relatively large rectangular opening for providing front and rear access to the hearth. A hood, disposed above the hearth and connected to the firebox, defines a flue in the top portion thereof for venting combu...

The disclosure is of improved "see-through" or visibly transparent anesthesia masks providing safety by electrical grounding. The improved masks are positively grounded between patient and anesthetic delivery system and may be moved freely on the face of the patient without interruption of the ground circuit. The improvement comprises, as a ground component for contact between an anatomical portion of a patient on which the mask is fitted and the anesthesia delivery system, an electrically condu...

A sump motor is mounted in a section of pipe. The motor is a standard motor having special caps at each end of the motor shell and with the shell forming a waterproof enclosure. The caps have radially extending spacers extending out to the pipe. At each end of the pipe are reducers, the internal diameter of the small ends of which correspond to the external diameter of another, smaller standard pipe size. At the bottom a piece of pipe of the smaller size extends inwardly of the reducer to a loca...

A flow-through porous electrode structure for electrochemical systems having flowing electrolytes is disclosed. The flow-through porous electrode structure includes a single porous electrode having two planar opposing faces, each of which provides a reaction surface for electrochemical electron-transfer reactions of the same polarity. The porous electrode features spaced passage means which extends at least in part through the electrode between the opposing faces for distributing the circulating...

An adjustable pass-through joint comprising a main joint body having a first bore longitudinally therethrough, a second bore orthogonally intersecting said first bore, a third bore intersecting said second bore and a fourth bore intersecting said second bore, a cylindrical locking member rotatably mounted within said second bore and having a partially-threaded opening in line with said first bore, a threaded rod slideably installed within said joint body, and a shaft insertable within said third...

A through-conduit, double-wedging parallel seat gate valve. The valve has a monolithic body forming a spherical segment with a cylindrical flow passage and flange end connections. The body has a transverse chamber mounting a rectangular gate moved across the passage between opened and closed positions. The chamber has an obround cross section with parallel sides facing the sides of the gate and rounded ends facing the edges of the gate. Integral parallel guide surfaces on the body separate the r...

Cooling beverages by the addition of ice cubes, dilutes the beverage as the ice melts. The present device comprises an insulated container having a low freezing temperature material such as a liquid or semi-liquid, sealed therein. A pouring funnel is provided at the upper end of the container with a spiral conduit extending from the funnel, downwardly through the liquid or material, to a discharge at the base. When frozen, a beverage can be poured into the funnel portion and flows downwardly thr...

A flow-through surge receiver for a refrigeration system having compressor, condenser and evaporator means, in which a surge-type receiver forms a reservoir for liquid refrigerant and has a flow-through conduit receiving refrigerant from the condenser means and an outlet for passing such refrigerant directly to the evaporator means in by-pass relation with the receiver reservoir, and a passageway for establishing fluid communication between said conduit and reservoir below the normal liquid refr...
