Abstract: ABSTRACT OF THE DISCLOSURE    An apparatus particularly adapted to installation in large railroad diesels or other large diesel applications which provides heated coolant for circulation in the large engine during shutdown or layover periods, also providing heat for accessories and electrical charge for batteries. Main engine fuel supply is used to run a small diesel engine which drives an inverter and a centrifugal pump, the discharge of which is severely stifled or throttled, the inefficiency of the pumping action converting much of the energy of the pump into heat ab-sorbed in the coolant which is then pumped through the regular cooling lines in reverse flow, and to accessories as desired.

Abstract: FLYWHEEL POWERED MOBILE: X-RAY APPARATUS                         ABSTRACT     A mobile X-ray apparatus (20) is disclosed which incorporates a power supply (22) in which the energy for operation of the Y-ray tube (21) is supplied from a flywheel (50) coupled to an electrical machine (24) which functions as both a motor and generator.  In the motor mode of operation, a controller (31) provides power to the machine (24) to operate it as a motor and drive the flywheel up to a desired operating speed.  Upon request of the operator to initiate an exposure, the controller power is disconnected from the machine and the power terminals (32) of the machine (24) are connected to a transformer and rectifier (27) which increases the generated voltage and rectifies it to provide the high voltage across the X-ray tube (21) required for proper exposures.  The controller (31) provides a first selected level of current to the control winding (77) of the machine (24) required during the motor mode for proper motor operation, and provides a higher selected current level to the control winding (77) during generator operation.  The controller also provides a boost in the control winding current as the machine (24) begins to supply power during an exposure to compensate for the voltage sag that ordinarily occurs upon loading of the machine to thereby maintain the output voltage substantially constant.

Abstract: ABSTRACT OF THE DISCLOSURE        A device for draining body fluids and irrigating solutions adapted for utilization with respect to operations on the human body, such as brain operations, eye operations, micro surgery and other types of operations, wherein a wick material, which may be used as a single unit or wherein a wick material, which may be separated or cut into sections, is connected to a drainage funnel or pouch which may be secured by adhesive or otherwise at the site of the opera-tion and wherein the wick material is capable of capillary absorption of fluids initially and when saturated, of acting in a siphon-like manner to draw fluids into the pouch.  The pouch itself at its lower end is connected by a tube to a collection bag which is appropriately vented.  For smaller incisions or for utilization at sites where fluid is to be drawn from relatively small areas or openings, the wick material instead of comprising a number of sections cut and shaped from the original wick material may comprise a single slender wick member which may readily be located at the said site.  In forming the wick material for utilization with respect to absorption of fluids from a larger incision, at least one of the sections which is formed may extend only to the edge of the incision in order to draw fluid which might otherwise be absorbed by the drape around the incision, thereby ensuring that all of the fluid is withdrawn into a pouch in which, if necessary, it may be examined or tested prior to being disposed of.

Abstract: ABSTRACT           A method for automatically reconfiguring the memory address space of a plurality of memory boards allows varying capacity boards to be arbitrarily assigned to backplane locations without human intervention.  By reading from a nonvolatile memory on each memory board, a processor can determine the proper address range to assign each memory board. It can then load the information into the board's configuration register and, if necessary, update the board's nonvolatile memory.  Each memory board then uses the addresses of incoming access requests and the contents of its configuration register to determine which memory components are to be accessed.

Abstract: Vortex Generating Flow Passage Design for Increased Film Cooling Effectiveness Abstract It is an object of the invention to provide a film cooling apparatus of increased effectiveness and efficiency.    In accordance with the invention, a cooling fluid is injected into a hot flowing gas through a passageway in a wall which contains and is subject to the hot gas.  The passageway is slanted in a downstream direction at an acute angle to the wall.  A cusp shape is provided in the passageway to generate vortices in the injected cooling fluid thereby reducing the energy extracted from the hot gas for that purpose.  The cusp shape increases both film cooling effectiveness and wall area coverage.    The cusp may be at either the downstream or upstream side of the passageway, the former substantially eliminating flow separation of the cooling fluid from the wall immediately down-stream of the passageway.

Abstract: ABSTRACT OF THE DISCLOSURE        There is disclosed a control system for a cycloconverter of the circulating current type to produce an ac current of a variable frequency and a system therefor.  This cycloconverter is configured to connect a power factor compensating capacitor at its receiving-end, thus to control a lagging reactive power due to a circulating current flowing in the cycloconverter so as to cancel a leading reactive power due to the power factor compensating capacitor.          Such a control is carried out under the condition of an operation below the rated load.  In contrast, under the condition of an operation above the rated load, a control is effected so that the circulating current flowing in the cycloconverter is substantial-ly kept constant.
