Calorimetrically sensitive resistance bridges are adapted for providing a read out which is a linear function of power, either in analog or digital display form, by duty cycle control of power pulses applied across the bridge for re-balancing purposes.

High frequency diodes are manufactured by methods in which extended dual mesas are formed upon a conductive substrate, one mesa incorporating the active junction and the other supporting the active mesa in reduced parasitic capacitive relation, with the substrate supporting the combination of mesas and with an efficient heat sink cooperating with the active mesa. Novel ringshaped diodes made according to the method feature a high degree of circular symmetry and therefore freedom from burn out, thermal compression bonding being used to perfect the bond between the active mesa and a diamond heat sink. Symmetry of the diode is assured by use of a novel photoresist mask generation technique.

Disclosed is a memory-unit-associated priority system that detects if information (data) sent to a memory unit was or could have been in error due to an asynchronous ''''priority request'''' signal being presented to the priority logic at the time the priority logic was being clocked (loaded).
摘要:
Apparatus for monitoring the operation of pairs of step data compasses, each being of the type which produces a number of phase-displaced pulses dependent upon the rotation of the compass. The apparatus includes circuits to form separate trains of UP or DOWN pulses in response to direction and magnitude of rotation of each compass. Each category of UP and DOWN pulses is stored in a separate pulse storage circuit and then sequentially clocked into an up-down difference counter. When the net change in the difference counter exceeds predetermined upper or lower limits, a corresponding pulse is applied to a difference accumulator. An alarm is actuated when the count stored in the difference accumulator reaches a value equal to that of an adjustable digital alarm set.

A geothermal energy transfer and utilization system makes use of thermal energy stored in hot solute-bearing well water to generate super-heated steam from an injected flow of clean water; the super-heated steam is then used for operating a novel turbine for driving a hot water pump at the well bottom for pumping the hot solute-bearing water at high pressure and in liquid state to the earth''s surface, where transfer of its heat content to a closed-loop boiler-turbine-alternator combination is effected for the generation of electrical or other power. Clean water is regenerated by surface-located equipment for re-injection into the deep well and the residual concentrated solute-bearing water is pumped back into the earth. The novel pump driving turbine features a compact and efficient steam turbine configuration adapted for use in the hostile environment of the deep hot-water well. Super-heated steam passes downwardly to impact turbine blades at the periphery of the turbine wheel. A further feature permits the expanding steam then to reverse its sense of flow in a compact arrangement returning the steam along the axis of the turbine wheel and then to the earth''s surface for further energy recovery.

A geothermal energy transfer and utilization system makes use of thermal energy stored in hot solute-bearing well water to generate super-heated steam from an injected flow of clean water; the super-heated steam is then used for operation of a turbinedriven pump at the well bottom for pumping the hot solute-bearing water at high pressure and in liquid state to the earth''s surface. There, it is used by transfer of its heat content to a closed-loop boiler-turbine-alternator combination for the generation of electrical or other power. Cooled, clean water is regenerated by the surface-located system for re-injection into the deep well and the residual concentrated solute-bearing water is pumped back into the earth. Significant axial thrust is developed in the support bearing system of the steam turbine driven hot water pump because of the considerable pressure head rise generated by the hot water pump, the axial thrust being proportional to the hot water pump discharge pressure. According to the invention, a balancing thrust is developed that is also proportional to pump discharge pressure, so that the net thrust is minimized over a range of speed and hot water flow conditions.
摘要:
A forms alignment indicator mechanism is provided wherein a bistable device is set to a first condition by a first predetermined command signal received from the print data source. The bi-stable device conditions the indicator mechanism and it in turn is rendered operative upon receipt of a second predetermined command signal from the data source. The receipt of any third predetermined command signal between the first and second predetermined command signal renders the indicator mechanism inoperative.
摘要:
There is disclosed herein an arrangement for terminating elements such as plated wire memory devices (which have the size of a human hair), wire resistor elements, or similar devices for connection to external circuitry. The arrangement is also suitable for coupling similar devices which are on different planes and are oriented either in parallel or at different angles. The arrangement includes positioning slots which serve as connecting lands as well as non-conducting walls to prevent short circuits between adjacent wires when molten solder is applied to the end of the wire.

A checking circuit for the decoder of an error correcting code and a method of the designing thereof is disclosed. The method involves an algorithm that checks the syndrome generator network logic of the decoder. The syndrome checker includes a parity predict network and a parity check network in which the parity predict network is a parity tree whose terms in combination with the terms that define the syndrome generator logic meet the properties of the algorithm.
