Abstract: Case 70 - Gen Kin ABSTRACT        According to the invention a vibratory apparatus is provided having a deck resiliently mounted relative to a surface bearing the vibratory apparatus, a clamp support for casting on the deck, and a piston freely movably mounted relative to the deck. Vibration imparting structure vibrates the deck to shake out and to loosen foreign matter adhered to the casting supported on the deck and simultaneously reciprocates and ricochets the piston relative to the deck to further shake out and loosen foreign matter on the casting. A hammer plate is provided on the deck in the path of the piston.  As the vibration imparting structure is operated, the piston is intermittently forcibly driven against the hammer plate to set up a different frequency of vibration than the frequency o the primary vibratory apparatus which enhance the shake out and cleaning function of the structure.

Abstract: ABSTRACT              FIBER OPTIC CONNECTOR              A fiber optical connector for splicing optical fibers end-to-end in axial alignment. The connector housing comprises a bottom section and three top sections, each hingedly attached to the bottom section.  The bottom section has chambers with the V-shaped grooves for inserting and properly orienting the optical fibers end-to-end.  The top end sections each contain lands or fingers which, when closed, urge the fibers into the correct position within the V-shaped grooves and lock them there by exerting pressure on the protective jackets surrounding the fibers.  The center top section has a land or finger which closes directly onto the end optical fibers, forcing correct and precise alignment and locking them in this orientation.  A tension or strain relief may be installed over the connector.  The connector permits final inspection of the fiber orientation and application of an index matching fluid prior to closing the center segment.

Inventor: KNUDSON ORLIN B
IPC: H02M3/07
Filed: 1988-06-21
Granted: 1992-06-16
Abstract: ABSTRACT OF THE DISCLOSURE An exponential multiplication power supply is described which is comprised of a plurality of stages each having the ability to store energy and each having a plurality of states, including at least a store state and a stack state. The plurality of stages are arranged in a network such that an input stage in the network is connected to receive a voltage fron an external power source and all subsequent stages are connected to at least one other stage for receiving voltage from and through the other stages. A control mechanism is attached to the network stages and operates to place these stages in a repeating sequence of states such that at least one of the stages receives a voltage which is the sum of the voltages stored in at least two other stages.  When a stage is receiving voltage or holding voltage it is said to be in the store state, and when a stage is combined with other stages to present an increased voltage, it is said to be placed in the stack state.  This exponential voltage nultiplication power supply is applied to the production of high voltage for exciting electroluminescent panels.  The application of this power supply includes compensation circuitry to vary the excitation in response to varying characteristics of the electroluminescent panel.

Abstract: ABSTRACT OF THE INVENTION                           A hash brown potato patty is formed from fresh potato shreds and a dry binder, deep fat fried and frozen for subsequent reheating in a conventional household toaster.  The dry binder is made from fresh potato pieces which are blanched, frozen, ground to appropriate size, dried at a temperature below the resolubilization temperature of retrograded amylose and subsequently added to the potato shreds.  The potato shreds are made by blanching and cooling fresh potato pieces and holding at a reduced temperature for a predetermined period of time.  After shredding, water and the dry binder are mixed with the potato shreds, such that the dry binder is uniformly hydrated and dispersed within the shreds.  During frying, the retrograded amylose in the binder forms an essentially continuous film around the periphery of the patty, reducing the oil absorption during frying and subsequent release during reheating.  The dry binder can be made from other sources of potato solids, such as mashed potatoes, rehydrated, dehydrated potatoes, or reject fresh potato pieces from commercial potato processing.
