Abstract: In a nacelle and wing combination where a vortex is shed from a side surface portion of the nacelle and said vortex burst prematurely to reduce lift, the improvement comprising a vortex control device located in an upwash region along the side of the nacelle to cause said vortex to form in the critical vortex control region where boundary layer is relatively thin and local velocity is relatively high. This strengthens the vortex to inhibit vortex bursting at the burst location.

Abstract: A control valve for limiting the flow rate of a fluidized medium to a hydraulic motor during start up of the motor so as not to induce loads which exceed predetermined torque limits of apparatus driven by the motor. The control valve includes a poppet which is spring biased to a seated closed position. Increasing inlet-to-outlet pressure differential unseats the poppet in a downstream direction uncovering bypass ports which allow an initial surge of fluid to the motor to accelerate the motor to a predetermined speed at a rate which does not exceed the torque limits. Further downstream movement of the poppet exposes greater cross-sectional areas of main inlet ports which permit additional modulated fluid flow to accelerate the motor to its operational speed. The rate of movement of the poppet in the downstream direction is limited by flow restrictor orifices which conduct fluid which is displaced from a chamber due to the downstream movement of the poppet.

Abstract: A pollutant removal/heat exchange apparatus is mounted to a wood burning stove to receive the emission products from the stove. The apparatus comprises a plurality of vertically aligned tubular electrodes which define vertical through passageways. Negatively charged disc-like electrodes are positioned within the tubular electrodes. Partially burned hydrocarbons and moisture in the emission products become negatively charged as they pass through the tubular electrodes to become deposited on the inner surfaces of the tubular electrodes. Ambient air is directed through the passageways between the tubular electrodes to extract heat from the emission products, with the heated air being discharged from the apparatus. The electrostatic precipitation of the material on the tubular electrodes not only removes undesired material from the emission products, but also enhances heat exchange with the ambient air passing through the apparatus.

Abstract: An ultrasonic probe for insonifying the ascending aorta of a supine or reclining human patient. The probe has a head housing transducers for insonifying the patient's ascending aorta and for intercepting doppler-shifted energy reflected from the proximate and distal walls of the ascending aorta and from blood flowing through the aorta. The transducer head is integral with and extends below the handle of the probe, facilitating the manipulation of the probe and alignment of the beam of ultrasonic energy propagated by the probe relative to the ascending aorta of the patient. An oval cross-section and trapezoidal profile allow this to be done with a minimum of discomfort to either the patient or the user of the probe, and an L- or T-shaped handle allows the probe to be positioned and manipulated from a position behind the patient's head and with little or no sight of the patient's suprasternal notch.

Abstract: A isothermal rebreathing apparatus and method for collecting human breath samples for chemical analysis of the ethyl alcohol content wherein the breath samples are obtained from a subject repetitively exhaling into the inhaling from an enclosed, flexible, variable volume, bag-like collection receptacle which is heated to maintain the breath sample enclosed therein at a prescribed temperature, preferably at or near the subject's body temperature, before extracting the breath sample for subsequent chemical analysis. The collection receptacle may be enclosed by an airtight chamber including heaters therein to warm the air around the collection receptacle in order to regulate the temperature of the breath sample therein. A bellows section in fluid communication with the heating chamber allows for inflation and deflation of the flexible collection receptacle while located in an airtight environment.

Abstract: An airfoil having a trailing edge flap assembly comprising a flap member having a pair of tracks mounted thereto at spanwise spaced locations. Each track member is operatively connected to a slide member which is in turn mounted to a stationary structure. The flap member is attached to the two track members by means of pivotal links and ball joint connections to alleviate problems relating to wing deflection and also differences in linear movement of the flap member due to conical movement from the stowed to the deployed positions. Other embodiments show specific features relating to the actuating means, the track location, and the slide member location.

Abstract: Protective helmets for work and sport. Each helmet has a base part to which a chin guard and two top parts are connected by sutures to form a flexible assembly which is capable of damping and absorbing shocks which would otherwise be transmitted to a head protected by the helmet. The sutures follow the sutures of the human skull which maximizes the protection afforded by the helmet.

Abstract: An electrically conductive tennis ball comprising a cover of woven fabric in which the yarn used for weaving the fabric in at least one direction is made by twisting together a blend of electrically conductive and electrically nonconductive filament fibers. The electrically nonconductive fibers may predominate, and the woof yarn may be thicker than the warp yarn which may be so woven with the woof yarn that the latter occupies the major part of the ball's surface. To promote continuity of the electrical paths in the ball's cover, an electrically conductive adhesive, or mat, or scrim or other base may be interposed between the woven cover, and an electrically conductive coating may be applied to the inner, or back, side of the cover. Needling may also be employed to reorient the fibers in the cover and thereby enhance the conductivity of the electrical paths along the inner side of the cover.

Abstract: Apparatus is lowered over the top of a tree to sever the tree top and to collect the severed tree for later use in reforestation. The apparatus includes a housing having a conically shaped inner passageway which diverges downwardly to provide a lower opening for guiding the tree upwardly through the downwardly diverging passageway to provide a lower opening for guiding the tree upwardly through the passageway and out the top of the conical housing. In an exemplary embodiment, the cutting assembly includes a movable engaging arm which is propelled in scissor-like movement toward a fixed engaging arm by a fluid cylinder/piston assembly. The inner edges of the arms are shaped to guide the tree toward a cutting blade attached to the inner edge of one of the arms. The tree is moved into cutting engagement with the cutting blade by the closing movement of the movable arm.
