Abstract: ABSTRACT OF THE DISCLOSURE    Disclosed is an electrical brake system for an electric rolling stock including a filter condenser and resistor-chopper.  If the voltage across the filter condenser is going to rise excessively due to an abrupt variation of the trolly load or a momentary coming off of the pantagraph from the trolly, it is detected promptly and the resistor-chopper connected in parallel to the filter condenser is operated so as to suppress the excessive voltage and at the same time reduce the resistor-chopper current automatically in accordance with the predetermined timing pattern, not to a complete cut off of the regenerative braking current, but maintaining the regenerative control, thereby allowing a quick restoration of the regenerative current when the power system is rid of the disturbance.

Abstract: ABSTRACT      An ultrasonic surveillance system which emits pulse--like ultrasonic waves to an area under surveillance, which statistically compares a reflected-wave pattern established by receiving ultrasonic waves reflected from the under surveillance with a predetermined reference pattern, and which produces an alarm signal when these two patterns are not in agreement.  In order to exclude ultrasonic noise having a relatively small amplitude from the reflected-wave pattern, a difference component between a pattern of frequencies of emitted ultrasonic waves and a pattern of the other frequencies is used as the reflected pattern.  The frequency components other than those of emitted ultrasonic waves are integrated and, when the integrated value exceeds a predetermined value, the transmission of an alarm signal is interrupted so as to prevent the system from being erroneously operated by ultrasonic noise having a large amplitude.  The number of peak values in the reflected pattern is counted and, when the counted value exceeds a predetermined value, the transmission of an alarm signal is also interrupted.

Abstract: A B S T R A C T           A central processor for a general-purpose digital data processing system.  The processor has a pair of caches, an operand cache for operands and an instruction cache for instructions, as well as a plurality of execution units, where each execution unit executes a different set of instructions of the instruction repertoire of the central processor.  An instruction fetch unit fetches instructions from the instruction cache and stores them in an instruction of a given program stack.  The central pipeline unit which has five stages obtains instructions in program order from the instruction stack of the instruction fetch unit.  In the first stage of the central pipeline unit, the instruction is de-coded; in the second, the address preparation of an operand whose address is included in the instruction is initiated; in the third cycle, the address preparation is completed and the operand cache is accessed; in the fourth cycle, the operand is selected from the operand cache; and, in the fifth cycle, the instruction and operand are transmitted to the one of the plurality of execution units capable of executing the instruction of the program in execution.  The results of the execution of each instruction by each execution unit are stored in a results stack associated therewith.  A collector unit causes the results of the execution of the instructions to be stored in a master safe store register in program order, which is determined by the order of issuance of the instructions by the central pipeline unit.  The collector also issues write commands to store results of the execution of instructions into the operand cache.

The alkaline sodium scrub-bing materials such as Na2CO3, NaHCO3, mixtures thereof such as impure trona ore may be used in the form of an aqueous slurry or aqueous solution to scrub SO2 from gases containing same to form a reaction mixture com-prising Na2SO3, Na2SO4, and optionally NaHSO3, and a gas depleted in SO2.  The reaction mixture is contacted with an aqueous hydrogen ion solution comprising Na2SO4 and H2SO4 formed in an acid compartment of a two- or three-compartment electrodialytic water splitter to form a solution comprising aqueous SO2 values and aqueous Na2SO4.  The contacting of the reaction mixture with the aqueous hydrogen ion solution may be performed exter-nally, in a reaction zone external to the water splitter or internally, in an acid compartment of the water split-ter.  A liquid comprising water is fed to a base com-partment of the electrodialytic water splitter to form a liquid comprising aqueous NaOH.  At least a portion of the aqueous sodium values in the aqueous Na2SO4 is transfered to the liquid comprising aqueous NaOH in the base compartment and an aqueous solution comprising NaOH is recovered from the base compartment.

Abstract: ABSTRACT A horizontal shaft oil pump is provided for use in a compressor comprising an outer housing having an inlet, an outlet, an oil pump, and a crankcase mounted therein.  The crankcase has a generally vertically disposed passageway therein in communi-cation with the oil sump, and a crankshaft is horizontally rotatably received in a bore in the crankcase.  A reduced diameter portion of the crankshaft forms between the crankshaft and crankcase an annular chamber in communication with the passageway, and a pair of oppositely angularly disposed helical grooves are disposed in the crankshaft on opposite sides of and in communication with the annular chamber.  Upon rotation of the crankshaft, a low pressure area is developed in the annular chamber causing lubricant to be drawn upwardly through the crankcase passageway and into the annular chamber.  The rotating helical grooves deliver lubricant from the annular chamber to opposite end portions of the crankshaft for lubricating bearings and other moving parts.
