Title: Scram valve assembly
Inventor: VOEGELI ERNST
IPC: G21D3/04
Filed: 1976-03-16
Granted: 1978-10-24
Abstract: ABSTRACT OF THE DISCLOSURE      A scram valve assembly is disclosed having a pilot valve governing the opening or closing of the scram valve. The operation of the pilot valve is directly dependent on instant conditions in the scram valve housing without any interposed sensors and/or signal transducers, using a negative pressure wave propagating towards the scram valve in the event of a line rupturing, thus considerably reducing the scram valve response time.  The arrangement according to the invention also increases reliability of operation of the assembly.

Abstract: ABSTRACT OF DISCLOSURE          Disclosed herein is an internal combustion engine comprising a combustion chamber, a crankcase, a piston movable relative to the combustion chamber and the crank-case to effect cyclical pressure variation in the crankcase in response to piston movement, a transfer passage for intro-ducing fuel-air mixture into the combustion chamber from the crankcase in response to cyclical crankcase pressure varia-tion, an auxiliary chamber separate from the transfer passage, and a port arrangement for providing the auxiliary chamber with pressurized air in response to cyclical crankcase pressure variation and for initiating communication of the auxiliary chamber with the combustion chamber in response to piston move-ment during the presence of pressurized air in the auxiliary chamber and at a time other than the time of initiation of introduction of fuel-air mixture into the combustion chamber. Also disclosed herein is a method of operating the internal combustion engine comprising the steps of supplying a fuel-air mixture to the crankcase during a condition of relatively low pressure in the crankcase, introducing air into the auxiliary chamber in response to establishing communica-tion between the auxiliary chamber and the crankcase during a condition of relatively low pressure in the crankcase, there-after pressurizing the air in the auxiliary chamber in response to establishing communication between the auxiliary chamber and crankcase during a condition of relatively high pressure in the crankcase, introducing the fuel-air mixture into the cylinder from the crankcase by establishing communication between the transfer passage and the cylinder during a condi-tion of relatively high pressure in the crankcase, and intro-ducing the pressurized air into the cylinder from the auxiliary (Abstract of Disclosure cont'd) chamber by establishing communication between the auxiliary chamber and the cylinder such that communication between the cylinder and the auxiliary chamber is initiated at a time other than the time of initiation of introduction of fuel-air mixture into the cylinder.

Abstract: SPEED COMMAND GENERATOR FOR ELEVATOR          ABSTRACT OF THE DISCLOSURE         A speed command voltage is generated which increases in proportion to the lapse of time so as to increase the speed of an elevator car at a constant acceleration after starting.  Another speed command voltage is generated which decreases with the reduction in the distance between the position of the travelling elevator car and the target floor position so as to decrease the speed of the elevator car at a constant deceleration.  The speed patterns provided by these speed command voltages are joined together to provide a continuous speed pattern for the elevator car instructed to travel to arrive at the target floor.  In order to ensure shock-free operation of the elevator car at the joint between these speed command voltages, the speed command voltages in accordance with respective speed patterns for use in acceleration and deceleration are compared with each other, and the increase in the speed command voltage for acceleration is ceased when the difference therebetween attains a predetermined value.          The speed command voltage is maintained constant at this level to provide a constant-speed command voltage.  Then, the constant-speed command voltage and speed command voltage for deceleration are applied to a lower-level signal passing circuit, in which two input signals are compared with each other and the lower level signal of them only is passed, to obtain a completely continuous speed pattern for the elevator car.  A reference command voltage is generated, which increases up to a predetermined level with the increase in the speed command voltage for acceleration, and the rate of increase of which decreases gradually upon attainment of such a level.          This reference command voltage is used to maintain always constant the length of time of this constant-speed command voltage.  The increase in the speed command voltage for acceleration is ceased to obtain the constant-speed command voltage when the difference between the speed command voltage for acceleration and the speed command voltage for deceleration is reduced to a value less than that of the reference command voltage.

Abstract: TITLE OF THE INVENTION           VOLTAGE COMPENSATED TIMING CIRCUIT          ABSTRACT OF THE DISCLOSURE         A circuit provides means for controlling the energy derived from operation of a load by delivering a timed output pulse which is a function of the applied circuit voltage.  Oper-ation of a variable charging means, coupled across the applied circuit voltage, is initiated by application of an input signal to the circuit and charges at a rate dependent upon the applied circuit voltage.  A differential amplifier, responsive to the condition of the charging means, controls a driver which operates a latch to determine the duration of the output pulse.
