Title: Cathodically protected water heater
Inventor: STUBBE JAMES S
IPC: F24H1/18
Filed: 1987-12-11
Granted: 1992-10-20
Abstract: ABSTRACT OF THE DISCLOSURE          A cathodically protected water heater which eliminates the need of a conventional anode rod.  The water heater tank includes a cylindrical shell enclosed by upper and lower heads.       The upper surface of the lower head is coated with a metal anodic to steel.  The inner surface of the shell and the upper head are coated with a corrosion resistant coating, such as glass or metal anodic to steel as well, and the upper edge of the flange in the upper head bordering the opening is welded directly through the metal coating to a flue which passes through the shell while the outer periphery of the lower head is welded to the lower edge of the shell.  The metal coating hydraulically seals the exterior weld between the upper head and shell from water contained in the heater and provides a corrosion barrier and anodic surface to contained water.

Granted: 1991-02-26
Abstract: ABSTRACT OF THE INVENTION      Disclosed is a gas lighter equipped with a safety lock, which is an L-shaped slidable stopper so slidably fitted in the reentrancy of the thumb-push gas lever that its vertical leg may be on the top of the lighter housing when its horizontal leg is pushed in the reentrancy of the gas lever,  thus preventing the descent of the gas lever for lighting, and that its vertical leg may be off from the top surface of the lighter housing when its horizontal leg is drawn to the full length, thus permitting the descent of the gas lever for lighting.  A gas lighter according to the present invention assures in its locking condition that an accident which may be caused when a child plays with the device, such as a burn or an accidental fire is prevented.

Abstract: A SYSTEM EMPLOYING A BIOSENSOR TO MONITOR A CHARACTERISTIC OF A SELECT COMPONENT IN A MEDIUM               Abstract of the Disclosure A measuring instrument is disclosed having a reversibly selective binding protein immobilized upon the insulated-gate region of a field-effect transistor located on a sensor With the sensor immersed in solution, the proteinbinds a select component of the solution to the gate producing an effect on a current flowing through the IGFET. A plurality of such binding protein-IGFET arrangements can be provided on the same sensor, including the same binding proteins having different binding coefficients KD or an array of proteins with different ligand specificity and/or affinity. Analysis of the IGFET's response to binding by a microprocessor allows, for example, the concentration of the component in solution to be determined. With a plurality of different binding proteins employed, the concentration of different components can be determined. Similarly, with binding proteins employed having different binding coefficients KD, the output of the sensor can be analyzed in either a digital oranalog manner, or some combination of the two. To release the component from the protein, heat can be applied to the sensor through a resistive bank integrated into the sensor chip. Alternatively, the application of a reverse bias to the gate can be used to enhance release.

Granted: 1995-07-25
Abstract: A harmonic coding arrangement where the magnitude spectrum of the input speech is modeled at the analyzer by a relatively small set of parameters and, significantly, as a continuous rather than only a line magnitude spectrum. The synthesizer, rather than the analyzer, determines the magnitude, frequency, and phase of a large number of sinusoids which are summed to generate synthetic speech of improved quality. Rather than receiving information explicitly defining the sinusoids from the analyzer, the synthesizer receives the small set of parameters and uses those parameters to determine a spectrum, which, in turn, isused by the synthesizer to determine the sinusoids for synthesis.

Abstract: ABSTRACT OF THE DISCLOSURE    Apparatus which eliminates mechanically-moving parts for clasping or releasing a sheet metal can body for moving a can body from a forming station and, which reduces the number of moving parts as well as the type of movements required by such transfer apparatus to enable sheet metal can bodies to be transferred rapidly, in synchronism with movements of tooling in a forming press without damage to sheet metal or coating while controlling orientation and stability of the can body.  A shuttle arm oscillates in the longitudinal direction of the can line, into and out of the area of the press tooling to transfer a can body for continued movement in the line; such shuttle arm move at a rate which does not obstruct any movement of the forming tooling or the operating rate of the press.  A formed can body is attracted to and physically held at the leading end of the shuttle arm in desired orientation without mechanical movement clamping of any type by a stacked array of permanent magnets and flux path bars.  Movement of the shuttle arm longitudinally in relation to a wiper-arm sepa-rates the can body at a desired location without requiring separate mechanical moving parts.  Such flux path bars present a surface which matches a portion of the contour of the can body.  A rigid-holding capabil-ity, with desired stability and orientation are provided.
