Abstract: A HYDRAULIC SYSTEM FOR SIMULTANEOUS          CONTROL, ESPECIALLY FOR THE CONTROL             OF ELECTRIC CIRCUIT BREAKERS                  Abstract of the Disclosure Two circuit breakers or circuit breaker modules are actuated by hydraulic jacks fed by supply and drain valves operated by a single closing-operation control unit.  A differential pressure detector is subjected to the pressure of the two jacks.  In the event of a relative variation in the jack-operating times, the free piston of the detector actuates a switching device which connects the supply and drain valves to the drain tank, thus preventing the complete performance of any non-simultaneous operation of the circuit breakers.

Abstract: MOISTURE SEPARATOR REHEATER WITH THERMODYNAMICALLY ENHANCED MEANS FOR SUBSTANTIALLY      ELIMINATING CONDENSATE SUBCOOLING     Abstract of the Disclosure A Moisture Separator Reheater (MSR) has a plurality of tube bundles which receive high-pressure saturated (tubeside) steam therein. Steam to be reheated (shellside steam) is passed in heat-exchange relationship with the tubes of the first and second reheater tube bundles after first being dried by the panels of a moisture separator. It emerges from the shell of the reheater dried and heated.          In the reheater tube bundles saturated steam at temperatures and pressures substantially higher than the shellside steam transfers heat to the shellside steam by condensation within the tubes, The steam in the second stage tube bundle is at a temperature and pressure that is substantially higher than that of the steam in the first stage tube bundle and is heating shellside steam at a higher temperature than the shellside inlet steam to the first stage tube bundle. A greater quantity of tubeside steam than is theoretically necessary is passed through the tube bundles. This excess steam causes scavenging of the tube bundle to substantially eliminate condensate subcooling and related instabilities. Scavenging steam is provided to the first stage tube bundle with essentially no thermo-dynamic loss by passing the exhausted scavenging steam from the second stage tube bundle through a high differential pressure (.DELTA.P) thermo-compressor where it is isentropically expanded. It then entrains a higher rate of exhausted scavenging steam from the first stage tube bundle. The mixed discharge from the thermocompressor is then fed to the inlet of the first stage tube bundle, resulting in a high rate of scavenging steam therein. Minimal thermodynamic loss is achieved since the first stage scavenging steam is reused to continually scavenge the first stage tube bundle, rather than being exhausted to a lower energy point in the system, as is conventionally done, as for example to a feedwater heater.

Abstract: ABSTRACT    The vitamin B12 (cobalamin) level of human blood and mammalian tissue is routinely assayed utilizing radioisotope dilution assay (RIDA) techniques.  The presence of vitamin "B12 analogues" in such samples, which analogues are erron-eously assayed as true vitamin B12 utilizing prior art RIDA techniques, has been determined.  Such errors are due to the fact that birding proteins commonly used in prior art RIDA techniques normally include proteins which bind both true vitamin B12 and previously unrecognized vitamin B12 analogues.  The errors caused by the B12 analogues are avoided by using a composition for binding vitamin B12 which is substantially free of substances which bind vitamin B12 analogues.  Moreover, by using both types of binders in separate assays, the amount of analogue present may be arrived at by taking the difference of the assays.

Abstract: BRAKE ADJUSTER HAVING RESHAPABLE    MEMBER DRAWN THROUGH A DIE                   ABSTRACT OF THE DISCLOSURE A brake adjuster providing compensation for brake wear. Fundamentally, the invention includes a casing attached to a brake housing and maintaining a spring follower therewithin  A shaft or pin is connected to the pressure plate of a brake assembly and is interconnected with a reshapable tube.  The shaft and tube pass through a die whtch makes swaging engagement with the tube. As the brakes wear, the tube is drawn through the die and is progressively swaged along the length thereof. The spring follower acts against the die to urge the die, tube, and shaft to a return position following release of brake pressure. Such action releases the pressure plate from forceful engagement with the brake disk stack.  In an alternative embodiment, the shaft can be eliminated and one end of the reshapable tube can be connected directly to the pressure plate or to a suitable connection member on the pressure plate

Abstract: Heat Recovery from an Internal Combustion Engine for Supplementary Power ABSTRACT:               Approximately two thirds of the energy of the fuel entering an internal combustion engine is dispersed in the form of heat.  Prior inventions indicate methods of utilizing a portion of this heat, but by requiring substant-ial changes to the internal design of the internal combustion engine, and/or its mode of operation. The invention herein recovers a larger portion of the waste heat by employing a heat pump cycle to elevate the temperature of low grade heat. Furthermore, the methods of heat recovery and utilization do not require internal design changes to the internal combustion engine; and so are applicable to existing engines.  This invention can therefore save more fuel than previous methods; and can do do on either existing or future intern-al combustion engines.
