Abstract: A B S T R A C T     Improvements to floating roof tanks for liquids, in particular to storage tanks used in the nuclear power industry.     The invention relates to floating roof tanks for liquids, of the type comprising a cylindrical wall (2), a floating roof (3), and a flexible membrane (4) connecting the periphery of the floating roof to the wall.  In accordance with the invention, means are provided for emptying the counter-pressure liquid which is located in the space (6) delimited by the membrane (4) and the wall (2) and which is open to the atmosphere.  These emptying means are disposed near the top of the tank so that the membrane, under the effect of pressure exerted by the liquid contained in the tank, serves to expel the counter-pressure liquid when the roof is in abutment against a top stop.  Such tanks are of particular use in the nuclear power industry for storing de-gased water to top up the primary circuit of a nuclear reactor.

Abstract: A Fast Writing Circuit for a Soft Error Protected Storage Cell Abstract A fast writing circuit is disclosed for a soft error protected storage cell, such as a latch.  The protected latch has a first input/output node and a second input/output node which are respectively connected to a charging source.  The latch is connected to a first binary state input device which is enabled by a write-enable input, the first node being selectively charged during a write interval when the write-enable input is on, to represent a stored, first binary logic state for the latch.  The soft error protection circuit includes an insulated gate, field effect capacitor having a diffusion electrode connected to the second node and having a gate electrode, for selectively loading the second node with an additional capacitance when its gate is biased with respect to the diffusion electrode.  The soft error protection circuit further includes an inverter circuit having an input connected to the second node and an output for applying a capacitance enhancing bias to the gate electrode of the capacitor, for capacitively loading the second node.  The fast writing circuit disclosed herein has an insulated sate field effect transistor disabling device having its source connected to ground potential, its drain connected to the gate of the capacitor and its gate corrected to the write-enable input, for removing the bias on the gate of the capacitor in response to the write-enable input, thereby minimizing the capacitive load on the second node during the write interval.  In this manner, the soft error protected latch can be written into at a faster rate than has been previously possible.

Abstract: IMPROVED SECURITY SYSTEM     ABSTRACT           A security system Having at least one electronic lock and one electronic key.  The electronic lock has a memory device which can maintain the data while there is no current supplied to the memory device, and alter the data only when current is supplied, thus providing a non-continuous current drain system.  The electronic lock further reduces the chance of error due to high velocity particles which can otherwise alter data in a memory device.  The electronic lock applies current to the memory only when a key has been inserted in the lock, and terminates the current to the memory when the key Has been removed or the function requested by the key is invalid or the function requested is completed.  Alternatively, the electronic lock may apply the current to the memory only if data is to be output from or input to the memory.

Selection of a knob position on the first scale provides a 100% magnetron duty cycle, or full "ON", cooking mode for the desired cooking interval, selection of a knob position on the second scale provides a first predetermined fractional duty cycle for "MEDIUM" power level magnetron operation for the desired cooking interval: and, selection of a knob position on the third scale provides a second predetermined fractional duty cycle for "LOW" or "DEFROST" power level magnetron operation for the desired cooking program interval.  A single timing motor drives a cam advance mechanism for effecting time-out of the selected program interval for the three power levels of operation.

Abstract: I.   ABSTRACT OF THE DISCLOSURE.     A soil tillage machine has a straight pull-type main frame.          Attached to the main frame are standards to which novel deep tillage knives are attached.  A pair of wings are attached to the lower part of the narrow knife shaped main blade.  The wings slope downwardly at an angle of approximately 10% relative to a line parallel to the soil surface.  The front portion of the wing bottom lies in a plane parallel to the soil surface.  The back portion of the wing bottom lies in a plane parallel to the top surface of the wing.  When the tillage machine is pulled through the soil, The wings on the knives lift and fracture the soil the entire width of the machine, breaking up any hard pan. This lifting action aerates the soil with minimal displacement and mixing of surface soil. The tillage machine can be used both before and after planting of crops.

Abstract: A system for providing information to alter the software of an electronic data processor embedded in an electronic module includes a remote reprogramming module that conducts a sequence of operations to provide data to the processor which the processor uses to reprogram itself. The system employs a data link having a bi-directional transmission path connecting the processor and the reprogramming module. A controlled switching circuit is provided at each end of the transmission path. Under normal operating conditions, the transmission path is used to transit a function signal for a function performed by the electronic module. Periodically, the processor operates one switching network to capture the path for transmission of a reprogramming inquiry signal to the reprogramming module. At the same time, the function signal is diverted to an alternate path internal to the electronic module. When the reprogramming module detects a reprogramming inquiry, it operates the other switching circuit to gain access to the transmission path. Then, in response to commands from the processor, the reprogramming module undertakes the reprogramming sequence and transfers data to alter program information held in the memory of the processor. Thereafter, both the processor and the reprogramming module operate their respective switching circuits to restore the transmission path to its normal operational use for the transmission of the function signal.
