Abstract: A ventable seal is provided for closing the open end of an electrochemical cell. The seal incorporates indentations formed in the outer surface of the centrally located hub that abuts a flexible diaphragm at a ventable interface. If a cell's internal pressure reaches an unsafe level and the seal ruptures, the indentations prevent resealing of the ruptured seal thereby avoiding a second build up of pressure within the cell.
Abstract: A substantially constant resistive force is applied to the drive motor of an automated ladler arm to prevent jerky movement of the arm during a downward or descending portion of its travel from a furnace to a mold. The force may be applied through an air cylinder connected to a pivoting loader arm.
Abstract: Products made of batter, such as pancakes, are automatically cooked on a continuous elongated, continuously advanced heated conveyor belt. A dispenser adjacent one end of the belt dispenses individual masses of the batter onto the belt to form the individual product units. At an intermediate location along the belt length, the product units are flipped. The dispenser and flipper are activated in synchronism with each other and longitudinal movement of the belt in response to the belt being continuously advanced.
Abstract: Apparatus for use in feeding physically incapacited persons comprising a spoon supported for orbital and rectilinear movement in a predetermined path, one or more receptacles, and kinematics selectively operable to move a selected receptacle into the path of movement of the spoon and for effecting orbital and rectilinear movement of the spoon from an at-rest position above the receptacle into the receptacle to pick up a quantity of food therefrom, remove it from the receptacle to a position to be received by the person and then return it to its at-rest position in readiness for a repeat cycle of operation.
Abstract: A fluid metering and transfer system is disclosed in which, in a preferred embodiment, a fluid contained in a reservoir is transferred in small amounts by a dipper wire to a conduit extending through the bottom of the reservoir. The fluid is then distributed by gravity flow through the tube to the desired location. The dipper wire is rigidly mounted onto a pivotable shaft. When the present invention is used for transferring lubricating liquid to machines, the shaft of the present invention can be coupled to a shaft of the machine so that the present invention only transfers and distributes the lubricating liquid when the machine is operating.

Abstract: A reserve supply of diazotype developing liquid from which liquid is supplied to semi-dry diazotype developing apparatus is maintained at both a substantially constant level and the required concentration of azo coupling component by introducing solvent for the liquid to restore the liquid level upon a decrease of the supply volume, sensing the specific gravity of the supply liquid by a hydrometer, and counteracting the decrease of concentration resulting from solvent addition by introducing a liquid concentrate containing the azo coupling component and electrolyte in response to a lowering of the hydrometer.
