Abstract: FITTING FOR STRUCTURAL PIPE-Abstract of the Disclosure An unthreaded, slip-on fitting for connecting a length of structural pipe to another length of structural pipe and/or to a stationary structural member such as a floor or wall, which is usable in building scaffolding, shelving, railing and the like.          The body of the fitting has extending from it a pair of spaced parallel arms between which a locking element is pivotally mounted on a transverse pin spanning the arms.  A set screw which is accessible from the exterior of the fitting body when the arms are inserted into the interior of a pipe to which the fitting is connected, engages a portion of the pivotal locking element extending into a cavity in the fitting body communicating with the slot.  When the set screw is advanced inwardly, the locking element is pivoted, moving outwardly in opposite directions a pair of pipe clamping surfaces on the locking element, to grip the interior of the pipe, thereby securing it to the fitting.          When the set screw is retracted, the pipe clamping surfaces of the pivotal locking element are released and free to move inwardly to unclamp the pipe.

Abstract: BEAM FORMING SYSTEM                 Abstract of the Disclosure A system for forming a beam of radiant energy which is incident upon or radiated from an array of radiating elements such as sonar transducers.  As a wavefront progresses across the array, samples of signals received by individual ones of the transducers are selected in accordance with specific beams to be formed, the selected samples being summed together through a sequence of partial summations until a complete summation of a sample of a beam is obtained.  The sequence of partial summations is initiated successively for each output sampling interval.  For a long array, wherein the transit time of a wavefront across the array is longer than the intersample interval, a plurality of the sequences are generated concur-rently.  All partial sums for all beam samples are generated periodically at the output sampling rate and are stored in a memory.  The address of the memory is permuted at a rate of one memory section per output sample interval whereby a presently calculated partial sum is combined with the partial sum of an earlier sequence.`

Abstract: ABSTRACT OF THE DISCLOSURE    A speed-responsive tag axle control system is disclosed including a comparison circuit which is operable when the rotational velocity of one driven wheel of a motor vehicle overruns the opposite driven wheel by a predetermined amount to simultan-eously brake the faster driven wheel and shift the vehicle load from the tag axle wheels to the driven wheels.  In one embodiment, a pressure fluid motor is connected between the tag axle and the vehicle chassis for normally transferring load from the driven wheels to the non-driven tag axle wheels, said motor being vented by said comparison circuit means to transfer the load back to the driven wheels upon the occurrence Or a driven wheel overspin condition.  In a second embodiment, the pressure fluid motor is connected between the driven wheels and the vehicle chassis, said pressure fluid motor normally being in the vented condition to cause load to be shared by the non-driven wheels, said motor being operable to the pressurized condition by the comparison circuit to effect transfer of load from the non-driven wheels to the driven wheels.

Abstract: MULTISTAGE HELICAL SCREW COMPRESSOR      WITH LIQUID INJECTION                 ABSTRACT OF THE DISCLOSURE      In a two-stage liquid injected helical screw gas compressor a bypass line with a check valve is provided between compressor stages for delivering compressed gas from the first stage directly to the compressed gas receiver and liquid reservoir.   Bypass of gas to the reservoir at startup assures pressurization of the reservoir and early flow of liquid to the first and second stage compression chambers.  As the working pressure in the second stage discharge line increases above first stage discharge pressure, the check valve closes and all flow from the first stage is conducted through the second stage compression chamber.

Abstract: Abstract of the Disclosure It is known to manufacture an osteosynthesis implantate, such as a bone nail or plate, in combination with a receiving coil and electrode connections to form an electro-implantate.  The coil and electrodes provide a small electrical voltage across the implantate and surrounding tissue to stimulate the healing process.  It is also known to convert osteosynthesis implantates into electro-implantate by the addition of belt-like or loose pick-up type coil elements.  The present invention relates to an attachment element consisting of a body support formed to attach to an ordinary implant-ate and which includes at least one induction coil and two electrodes, one of which is connectable with a conductive portion of the implantate, the other being exposed to bone or soft tissue of the patient.  The present invention may be applied to the implantate so that it can be converted into an electro-implantate during the progress of an operation with greater ease and less complexity then can either the belt-like or pick-up coil elements. Further, the result will be a fully equivalent and effective substitute for a pre-manufactured electro-implantate but at substantially less cost.

Abstract: FAN CYLINDER HAVING INVISIBLE EASED INLET              Abstract of the Disclosure Air moving mechanism is provided for equipment such as direct or indirect heat exchange cooling towers. Conventional cross-sectionally elliptical eased inlet structure leading to a fan opening or cylinder surrounding a rotary fan air mover is replaced by a much simpler, less costly, apertured airflow modifying baffle member which functions to define an invisible eased inlet for the fan.  The specially shaped aperture in the baffle member is configured and arranged relative to the fan cylinder inlet to cause air removed from the tower casing and directed toward the fan to follow a transition path between the baffle member and fan opening or cylinder which generally conforms to and substantially fills the opening or cylinder inlet around the entire circumference thereof.  In those instances where air enters the tower casing on one side, or on opposed sides of the fan structure only, the orifice in the baffle is formed of somewhat rectangular shape with edge portions thereof aligned with the air inlet sections of the tower in greater spaced relation-ship from the axis of the fan opening or cylinder than the remaining edge portions of the aperture to compensate for the more radial airflow patterns toward the cylinder or opening from the parts of the tower which receive ambient air as contrasted with the axially oriented airflow toward the fan cylinder or opening from the closed parts of the tower casing.

Abstract: Abstract The invention relates to an ASDE radar to supply information on airport surface traffic.  A well-known ASDE radar comprises an antenna having an elevation-depending gain factor    , for .omega.1<.omega.<.omega.2, where .omega.1, .omega. and .omega.2 represent angles of depression.  In case of the above radar the echo power of an airport surface target is independent of the distance, whereas the echo power of rain clutter is inversely proportional to the square of the distance.  Consequently, a remote surface target still pro-jected on the radar screen above the rain clutter, is likely to disappear in the rain clutter when approaching the radar; this may incur fatal consequences.  To solve the above problem, the ASDE radar of the invention comprises a combination of an antenna having a gain factor     , and a sensitivity time control circuit in its receiver.
