Abstract: ABSTRACT OF THE DISCLOSURE A random access memory is combined with a programmable logic array to count time pulses within an integrated circuit watch.  A master oscillator drives the internal timing clocks and serves as a time standard for a timing and control circuit means which manipulates data within the random access memory.  The timing and control circuit may contain a programmable read-only memory so that words stored within the random access memory may be read, and manipulated, in a selected sequence.  The program-mable logic array increments the word selectively read from the random access memory, compares it to a limit value and generates one or more flags according to the desired data manipulation.          Words stored within the random access memory may be selectively displayed by a liquid crystal display or light emitting diode display in a selected format determined by the programmable read-only memory.  A driver circuit coupled to the display may also contain a read-only memory so that the data may be displayed in a selected one of plurality of display fonts.  The operational and display modes may be customized by appropriately modifying the programmable logic array and read-only memories without altering the system architecture.

Abstract: METHOD OF STARTING UP TURBINES     ABSTRACT OF THE DISCLOSURE         At the point of time to when the turbine speed has come up to a first speed N1, a thermal stress expected in the turbine when the speed is increased to a second speed N2 at a rate .alpha.1 is presumed.  Thermal stress .theta.s(t)- .theta.sT1 at the point of time to1 for commencing acceleration to the second speed N2 is then obtained, which point of time to1 would never cause the maximum value of the presumed thermal stress to exceed a predetermined limit .theta.s? of the thermal stress when the turbine speed is increased at that rate.  Then, a length of time Tw1, referred to as a warming time, is determined which is required for the thermal stress .theta.s(t) to decrease to the level of (.theta.s(t)-.theta.sT1) when the warming is continued after the point of time to.  Subsequently, a length of time (N2-N1)/.alpha.1 required for increasing the turbine speed from N1 to N2 at the rate .alpha.1 is calculated.  The sum of the warming time Tw and the time required for acceleration is calculated to provide.  The lengths of time for starting T1, T2, T3 are found for each of' the acceleration rates .alpha.1, .alpha.2, .alpha.3 in speed.  The acceleration of the turbine is commenced at the time and with the rate which in combination provide the smallest sum T of time.

Abstract: Abstract of the Disclosure A subsoil plow having a plurality of forwardly facing C-shaped plow teeth arranged on a rigid frame in a generally V-shaped array.  Each plow tooth has an upper portion, a curved shank portion, and a bottom tip and is mounted on the frame by a so-called pivot bolt located directly above the tip of the tooth and by a shear bolt spaced from the pivot bolt, the shear bolt being adapted to fail in shear upon appli-cation of a predetermined load to the plow tooth, such as may be occasioned upon the tooth striking an under-ground object as the plow is pulled through the field, so as to release the tooth and to permit it to swing upwardly and rearwardly about the pivot bolt without the tip of the tooth digging deeper into the ground. Also disclosed is a hitch which enables the plow to readily be coupled to a tractor equipped either with a category 2 or 3N or a category 3 three point hitch with or without an automatic coupler.

Abstract: Title of the Invention:  UNITARY CAB AIR COOLING SYSTEM  FOR                         LARGE OFF ROAD VEHICLES.             Inventor:  Joseph L. Czyl ABSTRACT OF THE INVENTION            A vehicular air cooling-ventilating system which provides cooled, filtered, and dehumidified air for the operating cab of a large off the road vehicle in a unitary -package usually mounted in the cab overhead.  Unit utilizes available hydraulic fluid power for all shaft horsepower requirements.  A unique compensated drive system provides operation of the pulsating torque compressor load by a hydraulic motor prime mover.  The compensated drive system also provides operation in the presence of pulsating hydraulic fluid pressure commonly encountered in the supply of large vehicles.  Internal components are protected from contamination by an air operated vent cover.  Additionally, the difficult condensate handling problem caused by motion of the vehicle and consequences of condensate loss in the vehicle cab is overcome through the use of a flow metered baffle design in the condensate receiver.

Abstract: ABSTRACT OF THE INVENTION             An integrated circuit comprising first and second read-only memories (ROM), an adder circuit and a NOR gate for determining if the content of an input data word has more zeros than ones.  The invention is usable in core memories for the purpose of reducing the power requirements of the core memory.  Each of the read-only memories provides a set of output data bits which are less in number than the input data word.  These output bits are then applied to the adder circuit where it is determined whether the number of zeros is equal to or greater than the number of ones.  The output signals from the adder circuit are applied to the NOR gate which provides a signal to the core memory instructing it to convert all zeros to ones, and all ones to zeros, thereby effecting a reduction in the power requirements of the core memory.

Abstract: METHOD AND APPARATUS FOR MIXING TWO GAS CURRENTS     ABSTRACT OF THE DISCLOSURE               A method and apparatus for mixing a first relatively cool gas current and a second relatively hot gas current in a manner such that the resulting gas current has a relatively uniform temperature immediately subsequent to the point of mixing. The first gas current is separated into first and second partial gas currents, the first partial gas current being directed to a conduit which branches from the conduit in which the second partial gas current is directed.  The first partial gas current is directed at a relatively high velocity into a central nozzle in fluid communication with the second gas current while the second partial gas current is directed into a ring nozzle which also is in fluid communication with the second gas current and which concentrically surround the central nozzle.  The flow of the first gas current is regulated by throttling the second partial gas current while maintaining the flow of the first partial gas current The method and apparatus has particular application in the regulation of the inlet temperature to a heat exchanger of a cooling gas current in a dry cooling plant for hot bulk materials, such as coke.

Abstract: ABSTRACT OF THE DISCLOSURE        A tambour or roll-top door and housing assembly is provided herein.  The housing includes a pair of spaced apart tracks defining between them a path having a generally vertical first section with top and bottom parts, a generally horizontal second section near the top part of the first section, and a curved third section interconnecting the first and second sec-tions.  The tambour door has top and bottom parts, and side edges which are slidably disposed in the tracks of the housing, the door being movable along the path so defined.  The door comprises a plurality of longitudinal segments, each having opposite ends which define the side edges of the door, these segments being situated side-by-side with their adjacent edges pivotally engaged in a hinge coupling with a pitch distance P between the couplings.  The improvement provided a broad aspect of this invention comprises a shaft mounted in the housing and situated generally parallel to the door segments.  A gear means comprising a first gear is mounted rotatably on the shaft, the gear having teeth with a circular pitch distance between the teeth corresponding to the pitch P of the door couplings, with the gear situated such that the teeth thereof each engage one door coupling successively as the door moves in the path and the gear rotates.  A constant torque type spring, namely one which has the characteristics of substantially con-stant torque regardless of the degree of winding e.g., that known by the trade mark NEGATOR has an upper end coiled and freely rotatable about the shaft and a lower end secured to the bottom part of the door.  Thus, the door is subject to an esstentially constant force generally counterbalancing the downward force due to the weight of the door regardless of the location of the door along the path.
