A bank for collecting and safe keeping of coins or currency formed of two hemispherical members whose annular marginal edges are arranged to form a continuous annular gap therebetween when the bank is in the assembled and locked position. Access to the locking means is gained through the annular gap, any portion of which may be employed for inserting coins or even paper currency. Continuous lip means along the adjacent edges serve to prevent the currency from being removed.

A coin bank having a plurality of tubular members upstanding from a base, each tubular member having a predetermined cross-sectional area sufficient to receive coins of a particular denomination. The effective height of each tubular member is such that when filled with coins the number contained therein will fill a standard coin wrapper. There is a space of predetermined thickness between the stack of coins and the inner wall of the tubular member sufficient to permit the insertion of the coin w...

A toy bank device as disclosed for receiving and depositing coins comprising a base member adapted for location on a substantially horizontal surface and including base member mounting means. The base member has a base member orifice for receiving and storing coins within the base member. A support member has securing means which is cooperable with the base member mounting means for establishing the support to extend from the base member. A coin insertion member mounted relative to the support m...

A savings bank comprising molded upper and lower portions connectable to form a receptacle. The portions include engageable latch elements for securing the portions together so they may be disengaged upon insertion of a key.

A capacitor bank for use in high voltage electric plants such as series or shunt capacitors or in filter circuits for high voltage direct current plants. The capacitor bank comprises a number of capacitor units in a closed tank containing a gas for electric insulation and for regulating the temperature in the tank. Each of the capacitor units comprise a closed casing provided with bushings for current inlet and outlet, a number of capacitor elements connected together inside the casing and the c...

A thermal bank is comprised of a granular mass of polyvinyl chloride which surrounds a heating mechanism such as an electrical resistance heater or a conduit containing heated fluid. The granular polyvinyl chloride mass is formed by treating commercial dry flaked polyvinyl chloride with a small amount of stabilizer which causes the powder to form granules having interstices therebetween. The granular polyvinyl chloride mass not only serves as a high temperature insulator but also serves as an ex...

A visually interesting coin sorter and bank receives a group of random coins in a coin receiving chamber and ejects the coins one-at-a-time to roll to the bottom of a rotatable transparent spiral elevator plate or wheel. The spiral wheel lifts the rolling coins toward the center of the wheel until caught by size restrictions in the spiral to be then moved through an arc and to drop through a proper slot to form sorted stacks of coins. The spiral wheel is driven through an electric motor which is...

A toy bank of the type wherein a coin is launched at a target as part of the action in depositing the coin in the security portion of the bank, characterized in that the target has a plurality of target areas through which the coin may be fired and, if so successfully fired, falls on a return ramp behind the target areas constructed and arranged to return the coin to the exterior of the bank where it may be launched again. Also, further characterized by a coin receiving surface forwardly of the ...

A filter bank constituted in such a manner that an interdigital transducer on the input side of a plurality of each of surface acoustic wave filters having different pass bands is used as a shunt element and the shunt element is connected to a series element composed of reactance elements to form a ladder-type circuit, and a circuit composed of an inductor and a capacitor connected in parallel with each other is used as one part of the series element to form a pole near the cut-off frequency, to...

A portable load bank for loading a generator during a generator test has a set of low resistance coils mounted side by side in a housing and air cooled by a bank of fans. A switching network is provided for testing generators at three discrete load levels. An interlock circuit is provided for safety.
