Title: Electric power plant and turbine acceleration control  system for use therein

Abstract: ELECTRIC POWER PLANT AND TURBINE    ACCELERATION CONTROL SYSTEM       FOR USE THEREIN             ABSTRACT OF THE DISCLOSURE         An electric power plant having dual turbine-generators and a steam source which includes a high temperature gas-cooled nuclear reactor.  Each turbine includes a high pressure portion driven by superheat steam and a lower pressure portion driven by reheat steam.          A turbine bypass system permits minimum flows of superheat and reheat steam from the source at times when the tur-bines require flows of such steam that are less than the minimum flows.  Before it is reheated, steam that has passed through the high pressure portions and their bypass lines drives auxiliary steam turbines that rotate means for propelling the coolant gas through the reactor.  During acceleration of a turbine-generator to its synchronous speed, one of the steam flows through its high and lower pressure portions is varied to govern the shaft speed, while the other flow is held relatively constant, that one of the flows which is varied being determined by the shaft speed.  As the turbine-generator is accelerated, the steam flow through a bypass line associated with its lower-pressure portion is varied to compensate changes of flow through that portion, in order to maintain a desired pressure of hot reheat steam.

Abstract: SEMICONDUCTOR FABRICATION METHOD    FOR IMPROVED DEVICE YIELD     Abstract of the Disclosure A method for fabricating bipolar semiconductor devices of large scale integration in which the forma-tion of pipes, which result in shorts or leakages between two conductivity types of the semiconductor devices, is minimized.  Prior to forming the emitters in the bipolar transistors, nucleation sites for crystallographic defects such as dislocation loops are formed in the base region near its surface.  The emitters are then formed in base regions containing the nucleation sites and the sites are converted into electrically harmless dislocation loops during diffusion of the emitter impurity.  Preferably, the nucleation sites are formed by implanting non-doping impurities, such as helium, neon, argon, krypton, xenon, silicon, and oxygen.

Abstract: ABSTRACT         An inexpensive safety belt buckle of relatively small size and lightweight, yet capable of meeting the legal require-ments of safety, is disclosed.  The buckle includes a latch plate attached to one portion of the safety belt or structural member for insertion with reduced effort into a buckle body attached to another portion of the safety belt or structural member.  The length of the buckle is foreshortened by a bent latch lever pivotally mounted on the buckle body and biased for engagement with the latch plate to prevent withdrawal of the latch plate from the buckle body.  The height of the buckle is reduced by pivoting the latch lever downward to a release position which is below the plane generally defined by an upper surface of the base plate.          The buckle is readily assembled without expanding the side flanges of the base member.

Abstract: QUICK RELEASE FOR CATENARY ROLLERS                   ABSTRACT OF THE DISCLOSURE         Each end of a catenary carrier for an endless con-veyor belt is supported by a quick release mechanism oper-able to drop the catenary rollers out of operation.  The quick release mechanism includes a link which has an elon-gated slot with an enlarged annular end portion.  Supports at opposite ends of the catenary carrier carry a rotatable support pin for the link which has a head portion and a neck portion.  The neck portion is annular except for two flats formed on radially opposite sides thereof.  When the neck of the pin is disposed in the annular end portion of the slot, the link will be locked against movement relative to the pin in the direction toward the carrier if the flats are trans-verse to the slot.  When the support pin is rotated ninety degrees to present the narrow width of the neck in alignment with the slot, the weight of the carrier will cause the link to move relative to the pin whereby the neck of the pin will be disposed in the opposite end of the slot from said annu-lar portion.  This action drops the catenary rollers from their supporting relationship with the conveyor belt.  The opposite end of the slot is enlarged to permit the link to be removed from the head end of the pin.
