Abstract: SWITCH SCANNING MEANS FOR USE WITH INTEGRATED CIRCUITS     ABSTRACT Method and apparatus for generating a digital data word representative of the position of a switch element which is selectively engageable with one of a plurality of driver conductors which are utilized for conducting actuating signals from a source to a data display system of the type having a plurality of display elements for visually indicating alphanumeric data. The display elements have visually perceptible and imperceptible data indicating states and are characterized by a lagging response to either the application or interruption of the actuating signal wherein a turn-on or turn-off transition interval elapses during a change from one state to the other with the preexisting state of the display element appearing to an observer to remain unchanged during the transition interval. The actuating signals are periodically applied during a load energizing interval through one or more of the driver conductors and are interrupted during a sampling interval. The load energizing interval is much longer in duration relative to the duration of the sampling interval, with the duration of the sampling interval being substantially less than the duration of the turn-off transition interval. Each driver conductor is sequentially pulsed during the sampling interval with a strobe signal having a pulse component duration which is substantially shorter than the turn-on time of the display elements. A number of repetitive events are counted which occur during the interval commencing with the first application of a strobe pulse to a driver conductor of the array and terminating with the application of a strobe pulse to the driver conductor engaged in electrical contact with the data input conductor through the movable switch element. The number of repetitive events counted during the sampling interval is proportional to the number of strobe pulses applied to the driver conductors during the sampling interval and is therefore representative of the position of the movable switch element.

Abstract: ABSTRACT OF THE DISCLOSURE    An air conditioning unit including a compressor-expander employing a vaned rotor defining enclosed compartments which become smaller in the compressor and larger in the expander as the shaft rotates, for positive compression and expansion.  A primary heat exchanger having an associated separator-sump is connected between the compressor outlet port and the expander inlet port for dissipation of heat.  A secondary heat exchanger is con-nected between the expander outlet port and compressor inlet port for absorption of heat and to complete a closed loop.  The loop is charged with a main refrigerant in the form of a non-condensing gas, such as air, plus an auxiliary refrigerant mixed with oil, the auxiliary refrigerant being chosen (a) to have appreciable heat of vaporization and (b) to be capable of liquifaction at the pressure and temperature existing in the primary heat exchanger and evaporation at the pressure and temperature existing in the secondary heat exchanger.  A spray nozzle, fed from the sump via a first conduit, is provided at the inlet of the secondary heat exchanger so that droplets of auxiliary refrigerant are sprayed into the gas discharged from the expander for vaporization in the secondary heat exchanger.  A booster pump is optionally used to feed a stream of auxiliary refrigerant, plus oil, from the sump to the unit via a second conduit for purposes of lubrication and cooling.

Abstract: Abstract of the Disclosure In an axial flow rotary separator, a threshing or separating grate, surrounding and generally concentric with a rotor is made up of two generally semi-cylindrical halves.  An interconnected adjusting linkage arrangement is connected to and supports both halves adjacent their axially extending free edges.  Operation of the linkage moves both grate halves simultaneously and equally.          Each grate halve comprises two axially extending grate panels connected to each other so as to permit pivoting about an axis close to their inner surfaces and parallel to the rotor axis. Adjusting linkage action causes the diametrically opposite free edges of each grate portion to be displaced both radially and circumferentially with respect to the rotor so that the connected grate panels pivot relative to one another as adjustment is made and so that in all adjustment positions radial clearance between the rotor and inner surfaces of the grate, at the free edges of the grate and adjacent the pivotal connection, remains approxi-mately equal.  The gaps between the free edges of the grate portions are bridged by cover plates.

Title: Unloading means for flow-pressure compensated valve

IPC: F15B20/00
Filed: 1981-05-07
Granted: 1984-05-08
Abstract: Unloading Means for Flow-Pressure Compensated Valve A "load-plus" valve is oftentimes utilized in a servo-system to maintain pump discharge pressure above a minimum pressure level and above a load pressure signal generated in a fluid actuator. Valves of this type normally include a margin spring for biasing a modulating spool against the opposing force of discharge pressure to maintain a constant margin over the load pressure signal throughout the system working range. When the load pressure signal exceeds a maximum pressure level, it is normally vented to tank, or continuously bled to tank across an orifice, resulting in horsepower losses. A fluid circuit employs an unloading arrangement with the above type of "load-plus" valve to inactivate the margin spring to reduce the above margin between the pump discharge pressure and load pressure signal to zero in response to the load pressure signal exceeding a maximum pressure level.

Abstract: ABSTRACT OF THE DISCLOSURE           A low pressure drop air flowmeter (10) for an automotive engine is disclosed.  The meter includes a main air flow passage (26), a relatively small venturi tube (28) receiving a portion of the air flow, a pressure port (74) for sensing stagnation pressure in the main passage, a pressure port (70) for sensing static pressure in the throat of the venturi, and a complimentary pair of sets of stationary swirl vanes (30 & 32) disposed adjacent the outlet of the venturi and operative to jointly impart a swirl through the remainder of the air in the main passage, thereby creating a reduced pressure at the venturi outlet for amplifying the pressure difference between the stagnation and static pressures without appreciably increasing the pressure drop across the flowmeter.  The sets of swirl vanes are rotationally displaceable with respect to one another, allowing some of the air to bypass the effect of the swirl vanes without being diverted to a separate passageway.  This arrangement results in a fluid flowmeter having a characteristic pressure drop which is less than that for a conventional device, particularly at high flow rates, and which can be easily reconfigured to suit a specific application.  Also disclosed is a solenoid valve (54) operative to selectively sample stagnation pressure in the main flow passage and signal pressure in the throat of the venturi and generate an electrical output signal as a function of the difference between these two pressure signals.

Abstract: ELECTRIC FAN ASSEMBLY     Abstract of the Disclosure An electric fan assembly comprises a generally cylindrical cross-flow fan, a rear guide and a stabilizer.          The rear guide has a downstream edge with respect to the direction of flow of air to which a plate is hingedly connected.  By using the adherence effect of the air current to this plate, the direction of the air current is controlled by pivoting the plate.  A relatively slight pivotal movement of the plate is sufficient to bring a larger deflection of the air current.  The assembly can be employed in a heater or air-conditioner in which case a relatively high efficiency can be appreciated, with relatively little change in overall flow arising from changes in the angle of deflection.
