An improved dynamic logic gate compatible with a four-phase, major-minor clocking scheme and a six-phase metal oxide semiconductor (MOS) system. The gate evaluates only during an in-between clock phase, which phase corresponds to the interval of time between the occurrence of first and second major clock phases.

A memory using MOS (metal-oxide-semiconductor) structures comprises a memory matrix of an even number of memory cells divided into two groups. One terminal of every cell is connected to a respective select bus located along a memory matrix line. The other terminal of memory cells in a first group of memory cells is connected to a first number bus of the respective matrix column and the other terminal of memory cells in a second group of memory cells is connected to a second number bus of the res...

Method and apparatus for producing light metal alloys, in particular aluminum alloys, in which the desired alloying elements are first introduced into a vacuum furnace which is then evacuated, whereafter light metal melt is introduced into the furnace chamber by suction in the form of a free-falling metal jet which is thereby subjected to a vacuum treatment for reducing the contents of impurities, such as hydrogen, sodium, oxides and other non-metallic particles, therein. The free-falling metal ...

An improved dynamic MOS RAM employing capacitive storage memory cells having a single active device per cell. The RAM includes several improved circuits and techniques which reduce power consumption and pattern sensitivity and which also provide a higher speed memory. Complementary input/output lines are employed which are coupled to alternate pair of the bit-sense lines making the use of a bistable output latch and push-pull output buffer more advantageous. The sense amplifiers associated with ...

Dynamic timing indicating apparatus has comparing, zero-crossing detecting and automatic indicating apparatus. The comparing apparatus receives a first input signal and delivers an output signal in response to the input signal. The zero-crossing detection apparatus receives a second input signal which has a zero crossover portion and occurs in timed relation to the first input signal and delivers an output in response to the second input signal. The indicating apparatus automatically indicates t...

A filtering system for use in an FM modulating system. The filtering system provides frequency limiting of an input signal and does not overshoot amplitude limitations thereof. This filtering system includes a first filter and a second filter, separated by an overshoot compensator. The compensator modifies the output of the first filter in such a manner that, when the modified signal is filtered by the second filter, an output signal will be provided which does not overshoot a preselected amplit...

Method and apparatus for controlling a dynamic soil compaction operation, involving striking the soil with vibrating compacting tools, monitoring the vibrational power generated by the tools or the current degree of soil compaction, and controlling the amplitude or frequency of the vibratory movements of the tools as a function of the value of such quantity.

A dynamic mechanical system is driven at its resonant frequency by a drive system which maintains the vibrational amplitude of the system constant. A displacement transducer senses the mechanical displacement of the system and provides a displacement signal which is used to generate a control signal related to the energy necessary to maintain the mechanical system in resonance. The zero crossover points of the displacement signal are shifted in-phase 90.degree. and used to selectively switch the...

1. An electronic ordnance fuze adapted to function upon receiving a target ignal that increases in amplitude for at least a predetermined length of time, said fuze comprising: input means adapted to receive an alternating-current signal of increasing amplitude; first means for obtaining from said alternating-current signal a first negative-going unipotential signal of increasing amplitude, a ripple frequency due to the original alternating current being superimposed on said unipotential signal; ...

A technique is disclosed for locating the exact machine cycle, in a cyclic operation for a data processor, where an error occurs. Each cycle of the data processor is identified and counted as a cycle where the machine stopped with an error indication that is recorded. The cycles are then all caused to reoccur up to the cycle just preceding that cycle recorded and the machine is caused to stop without allowing the recorded cycle to occur. At this point it is determined whether an error did in fac...
