Title: Process for controlling the power delivered by a pressurized water nuclear reactor to a steam turbine.
IPC: G21D3/12
Filed: 1981-02-11
Abstract: A method for regulating the power supplied to a steam turbine by a pressurized water nuclear reactor driving an electric current generator supplying a network by utilizing the movement of control rods in the reactor and the by-passing of a fraction of the steam produced by the reactor out from the turbine circuit. In the case of electrical uncoupling between the generator and the network or load rejection, the parameter determining the position of the control rods is selected as the greater of two values of a reference temperature. The by-passing of the steam is kept in operation and the operation of the reactor remains automatic. The opening signal for the by-pass valves is modified by a gain signal determined from a signal representing the power level. The invention is particularly applicable to the regulation of the power of pressurized water nuclear power stations.

Title: Sliding gate valves and methods of operating them.
IPC: F27D3/15
Filed: 1984-03-23
Abstract: A sliding gate valve assembly employed on the side of a furnace as a furnace valve is so structured that the shut off of metal flow from the furnace occurs by directing the slide gate (21) to the up position rather than the down position. In addition, to facilitate a reduction in space at the slide gate, the slide gate is desirably configured to be asymmetrical, with the short end extending upwardly from the pour opening (29) in the nozzle. A refractory lined heat shield (26) protects the sliding gate carrier (22) and also serves to mount a collector extension (30) when used. The slide gate (21) is provided with a metallic frame (60) which retains a monolithic refractory (80) into which erosion resistant refractory inserts or performed members (29,70) are cast. Means are desirably provided to remove the spent refractory for remanufacture thereby reclaiming the casting. Similarly in the stationary plate (20), means are provided for remanufacture and for facilitating proper orientation of erosion-resistant refractory inserts in the manufacture of the stationary plate. The stationary plate is symmetrical to provide full travel pressure face relationship with the sliding gate (21). Both the stationary plate (20) and slide gate (21) casting have spring pad back up reinforcements. The statutory plate desirably has means for securing a well nozzle (19) to it.

Title: Bolt assembly with a rotating locking bolt head and a floating bolt element for automatic firearms.
IPC: F41A3/00
Filed: 1984-05-04
Abstract: A bolt assembly for an automatic firearm which operates using kinetic recoil energy that includes a floating bolt element, a rotatable locking bolt head and a return spring interposed between them, all in communication with the barrel. The bolt head is formed with a cylindrical portion having two crescent shaped projections located at diametrically opposite points along the circumference of the cylindrical portion. The barrel is formed with two diametrically opposite recesses associated with and shaped to correspond to the projections. The barrel is also formed with a pair of grooves, each groove associated with a recess such that the projections may enter and exit the grooves through the recesses. The grooves are staggered with respect to the recesses and have an angular extension such that the projections may enter and be retained within the grooves. The barrel is additionally formed with projecting edge guide grooves and the bolt element is formed with projecting edges that are guided by the projecting edge guide grooves. The bolt head is also formed with a shank and a cavity is formed in the bolt element for receiving the shank. The shank carries a pin that is adapted to impart a rotary movement to the bolt head by engaging a helical slot formed in the bolt element. Upon firing, the return spring is compressed which momentarily keeps the bolt head in a locked position which causes a delay to allow for the dissipation of pressures in the barrel.
