Abstract: ANTI-STALL CONTROL                        Abstract An anti-stall control for use in a system having an engine which drives a pump to supply fluid under pressure to a motor and including means responsive to a control voltage for altering the flow of fluid to the motor.  The anti-stall control senses the speed of the engine and generates a voltage proportional thereto, the speed voltage being compared to a reference voltage for Providing a D.C. signal proportional to the speed voltage.  A quick dump/slow recovery circuit is responsive to a decrease in the amplitude of the D.C. signal for generating a control voltage which decreases at a fast rate to prevent overloading of the engine, the circuit being responsive to an increase in the D.C. signal for generating a control voltage which increases at a slow rate to improve the stability of the system.

Abstract: MEANS FOR ADJUSTING HAY CONDITIONER ROLLS                   Abstract of the Disclosure Disclosed is a hay conditioner of basically typical construction in which the improvement lies in adjustable stop means for use in setting and varying the clearance between the upper and lower conditioning rolls.  There is provided at each side of the machine a means including a lever arm disposed below a support for the upper roll and pivoted at one end on the adjacent side of the machine frame, the other end being connected to a screw-threaded adjustment link effective to elevate the lever for engagement with the upper roll support and thus to selectively limit downward movement of the upper roll under action of the usual biasing means.  Thus, the upper roll is free to move upwardly in response to crops passing between the rolls, but its downward movement is limited to the stopped position selected by the adjustment link.  The link extends upwardly to a free end that is easily accessible to receive a force-applying tool.

Abstract: ELECTROHYDRAULIC DRIVE FOR PROCESS LINE  WINDERS, UNWINDERS AND OTHER EQUIPMENT          Abstract of the Disclosure An electrohydraulic drive for process line equipment, especially a spooler that winds and pays out an indefinite length of metallic strand, varies the output torque of a hydraulic motor by controlling its displacement and the pressure differential between its inlet and outlet.  A valve controlled by a proportional actuator reduces the supply pressure of the hydraulic fluid in a feed line for the motor.  A sequence valve located in a return line from the motor maintains the pressure at the motor outlet at a preselected and adjustable value.  During braking, fluid from the return line is directed to a regeneration circuit that includes a flow divider.  A portion of the flow is returned to the feed line to conserve the fluid flow.  Another portion is returned to a supply reservoir for cooling.  A servo-amplifier circuit includes an integrating amplifier that compares the actual rotation speed of the motor to a speed command signal.  An analog multiplier produces a control signal for the proportional actuator that is the scaled product of the output signal of the "speed" amplifier and a pressure limit signal.  In the preferred form a tensiometer monitors strand tension and produces an input signal to a computer that modifies the pressure limit signals.  The computer interfaces with other input and output devices and also controls the speed command and displacement of the motor.  A hydraulic cylinder controls the linear traversing movement of the spooler under the control of a high speed servo valve that in turn is controlled by electronic circuitry.  Position, velocity and rotation speed transducers for the spooler and a position transducer for the strand provide input signals to the circuitry.

Abstract: Abstract An expansion body for constructions like piles or anchor-ages located in the earth is adapted for insertion into the ground in a compact shape and expanded therein to an expanded shape.  The expansion is achieved by unfolding a folded metallic casing by fil-ling it up with pressurized fluid.  Each end of the elongated body is sealed by a closure comprising a socket with a sleeve encircling the near end part of the casing and a bottom plate with spacing means projecting into the inside of the casing.  The sleeve and spacing means define an annular space in which the end parts are kept in a folded position when the body is expanded.

By constructing the illuminator with an electric discharge lamp and a filter which removes the visible region and permits the near-infrared region to pass therethrough out of light rays radiated from this electric discharge lamp, there can be provided a near-infrared ray radiation illuminator having a high efficiency and low deterioration characteristic.  And, at the same time, by constructing a near-infrared ray image pick-up device with this near-infrared ray radiation illuminator and an image pick-up device which captures reflected light of the near-infrared ray radiated from the illuminator to be irradiated onto the object for the image pick-up, the image pick-up can be done without notice of a human being, whereby, when the device is used as a crime-preventing monitoring device, the monitoring of an intruder can be done perfectly, and, when it is used as a visitor congnition device, there is no disagreeable feeling on the part of the visitor by his being dazzled by illuminating light or his knowledge of being pictured by the device.

Abstract: S-60,734 ABSTRACT OF THE DISCLOSURE    A non-destructive method for determination of neutron exposure and constituent concentrations in an object, such as a reactor pressure vessel, is based on the observation of characteristic gamma-rays emitted by activation products in the object by using a unique continuous gamma-ray spectometer.  The spectrometer views the object through appropriate collimators to determine the absolute emission rate of these characteristic gamma-rays, thereby ascertain-ing the absolute activity of given activation products in the object.  These data can then be used to deduce the spatial and angular dependence of neutron exposure or the spatial constituent concentrations at regions of interest within the object.
