Abstract: Endogenous and exogenous proteins, and fragments thereof, are chemically modified outside the body of an animal so that when injected into the animal they produce more antibodies against the unmodified protein than would injection of the unmodified protein or fragment alone. The chemical modification may be accomplished by attaching the proteins or fragments to carriers such as, for example, bacterial toxoids. The chemical modification can also be accomplished by polymerization of protein fragments. Proteins which can be modified include Follicle Stimulating Hormone and Human Chorionic Gonadotropin. The modified polypeptide may be administered to animals for the purpose of contraception, abortion or treatment of hormone-related disease states and disease disorders, treatment of hormone-associated carcinomas, and to boost the animals resistance to exogenous proteins, for example viral proteins.

Abstract: In a free piston Stirling machine, a gas spring apparatus for applying two distinctly different spring rates to the displacer during the displacer's excursion past a center point in opposite ends of the work space. The apparatus comprises a cylinder formed in a gas spring housing, in which a gas spring piston is slidably mounted. On opposite sides of the gas spring piston there are two unequal volume gas spring chambers. Between the gas spring chambers there is a bleed hole which divides the cylinder into the two chambers and allows communication between the gas spring chambers and a gas reservoir. While the piston is compressing one gas spring chamber, the opposite is in communication with the gas reservoir and vise versa. This creates two distinctly different spring rates applied to the displacer.

Abstract: Galvanic protection of steel is provided by means of coupling thereto of ternary alloys of Al/2.5 to 4% wt. Mg, 0.5 to 35% wt. Si, and Al/2.5-4% wt. Mg, 0.5 to 3.5% wt. Ge with teachings of steel having either alloy coupled thereto, as well as the alloys per se. Also, a technique for determining alloys useful for the cathodic protection is presented including determining the critical cathodic protection potential for steel and the galvanic current and corrosion potential for candidate alloy compositions followed by coupling to the steel of one such alloy composition whose determined corrosion potential is lower than the critical corrosion potential for the steel in the corrosive environment in which protection is sought.

Abstract: The invention is directed to an apparatus and method for controlling the overflow of molten material from a receptacle for the purpose of achieving more uniform casting of the molten material. The apparatus and method utilize a force detector able to detect the change in the buoyant force exerted on a submersible body lowered into a molten material. A differentiating means, a control means, and a drive means are responsive to the force detector, whereby a constant rate of change of buoyant force is translated into a uniform rate of overflow of molten material delivered to a heat extracting substrate for solidification.

Abstract: A reel threader for treading the tail of a paper making web around a partial reel. A flexible panel with interior passages forming an air distribution network has openings on one surface to provide a plurality of air streams out of the surface. The panel is positioned by a computer controlled movable support frame in an arc which is spaced from and concentric with the lower and side portion of a partial reel, regardless of its diameter, to form a gap. The tail passes from the nip into the gap and is pulled through the gap by the rotating periphery of the partial reel.

Abstract: The subject invention relates to the art of adjustable wrenches. The adjustable wrench of this invention is particularly suited for the gripping of hex head fasteners. The adjustable wrench has a handle portion and a head portion. The head portion has two downwardly extending jaws. One jaw is stationery, the other being moveable. The moveable jaw moves in an elongated slot which is integral with the head portion. The moveable jaw and the elongated slot incorporate opposing interlocking surfaces which cooperate in such a manner as to support the moveable jaw during usage. The moveable jaw is connected to an adjusting means which may be an adjusting screw and an adjusting nut. The adjusting means controls the fixed relationship between the moveable jaw and the fixed jaw. In the embodiment which utilizes an adjusting screw its movement and hence the movement of the moveable jaw is controlled by the rotation of an adjusting nut.

Abstract: A method and means for superimposing a secondary, higher frequency, lower amplitude oscillation of the angle of the trajectory of a glass fiber relative to a forming surface upon a primary, lower frequency, higher amplitude oscillation of the release mechanism.

Abstract: A tray type food container having a pair of side panels extending from opposite sides of the lid and folded toward the bottom of the tray. An end of each side panel extends beyond the interposed tray side wall and supports the tray in a generally vertical orientation. A single partial incision or half cut is formed only inward of the tray rim to aid in the controlled fracture of the lid when it is torn from the tray.

Abstract: A vertical removable bulkhead is specified for use in a freight carrier bed with sidewalls, particularly pickup trucks, to divide and support cargo. The bulkhead is constructed of a rigid material and is suspended by hangers from the top edges of opposing truck bed's sidewalls. The hangers are cantilevered extensions of the bulkhead wall part and are made an integral part thereof for suspension in the truck bed without the use of connecting hardware.

Abstract: A mechanical refrigeration process in which two or more systems are connected in series to provide successively lower temperature levels. Each system utilizes mixtures of refrigerants and/or inert gases having different boiling points. The mixture is compressed to a suitable pressure and compression heat is rejected to the environment. The mixture is cooled by heat exchange with mixture returning to the compressor. The liquid and gas phases are separated and the separated gas mixture is further cooled to form liquid, by heat exchange with mixture returning to the compressor. The liquid is expanded to a given lower pressure to achieve the desired low temperature. The expanded fluid absorbs heat to provide refrigeration. The liquid expanded to the lower pressure is mixed with the used fluid which absorbed heat to provide refrigeration. The capacity of the system is controlled by throttling the compressor suction.

Abstract: The invention is for the prevention of power piston overstroke in a Stirling cycle machine, wherein there is a gas valve which vents the gas spring acting upon the displacer. The valve and its accompanying control system switch on a leak in the gas spring to vent the gas spring upon piston stroke beyond a selected magnitude. This reduces the spring constant which reduces the displacer amplitude and phase lead over the power piston and thereby reduces power output.

Abstract: A method and apparatus for illuminating a weld line wherein a beam of light is directed onto a weld electrode and is reflected off of the electrode, thereby illuminating an area of the weld joint. Also disclosed are an apparatus for detecting a weld line using light from a low power arc which does not form a molten pool and a method and apparatus for locating a weld line by analyzing light reflected from a weld pool.

Abstract: An apparatus for detecting the relative position of a remote object, such as a vehicle, upon a construction or agricultural site in cartesian, polar or other coordinates. A laser light beam is scanned in a circular path from a selected reference point at the site through a generally horizontal plane above the site. A pair of photo detectors which are spaced a selected distance are mounted to the remote object in the plane of the scanning beam. The beam is scanned at a constant velocity and the time of its alignment along a reference radial, and its interception with each of the two spaced photo detectors is detected and used to compute the position of the remote object.

Abstract: A heat extracting substrate is moved along a melt front formed at the edge of the surface of a molten material so that a layer of molten material is deposited on the substrate, cooled and removed from the substrate to form ribbon, filaments, fiber or film directly from the molten material. The edge may be formed by providing an upper edge upon a portion of the wall of a receptacle lower than the top of the receptacle. The molten material may be overflowed over this relatively horizontal edge and against the moving substrate surface.

Abstract: A compensation winding for improving the linearity of a displacement transducer. The displacement transducer is the type having an electrically conducting non-ferromagnetic wall which moves in telescoping relation with the coil and is excited by a signal at a sufficiently high frequency that skin effect on the wall permits displacement of the wall to vary the reluctance of the coil flux path and thereby vary its inductance proportionally to displacement of the wall. The compensation winding is wound in telescoped, coaxial relationship to the coil in a fixed position. The compensation winding has a pitch which is a decreasing function of the distance from the end of the coil which is nearest the wall when the wall and the coil are in their least overlapping relationship.

Abstract: Glass fibers are projected along an oscillating trajectory onto a travelling conveyer to form a glass fiber mat. The trajectory is made to oscillate by stripping glass fibers from a pulling wheel by means of a stripping edge, such as a tight wire, which is oscillated arcuately immediately adjacent the surface of the pulling wheel. The stripping means is oscillated at a greater angular velocity where the trajectory makes a greater angle with the conveye=r in order that the impingement point of the trajectory upon the conveyer travel at a substantially uniform velocity across the conveyer so that a mat of uniform density is fabricated.
