Abstract: In a solid fuel ramjet in which a fluid flow boundary layer extends along a urning fuel grain and receives combustible material liberated from the grain, exciting oscillations in air flowing toward the grain so that oscillations continue in the boundary layer and promote vortices in the layer to mix the air and the combustible material.

Abstract: In a combustor in which a flow area for fuel and air increases suddenly at dump so as to generate vortices which mix the fuel and air for combustion downstream of the dump, the improvement in which the flow cross section upstream of the dump is noncircular, as triangular or rectangular, causing flow downstream of the dump to be noncoherent so that mixing by the vortices is aperiodic with the result that heat release on mixing is uniform in time and does not drive oscillations in the combustor.

Abstract: The invention provides an improvement in a conventional recoil system comsing a piston-cylinder arrangement, wherein a piston driven by recoil energy forces hydraulic fluid out of the cylinder through an orifice to dissipate recoil force. The invention provides an additional flowpath for hydraulic fluid, which contains a servo valve for controlling the pressure in the cylinder so that the desired recoil peak pressure/time curve can be achieved for any firing impulse. The invention also includes sensors for measuring hydraulic fluid pressure and the initial velocity of the recoiling parts imparted by the firing impulse, and a controller means including a microprocessor for calculating or determining the desired peak pressure based on this initial velocity and available recoil distance and transducers for measuring any variation of pressure from the desired peak pressure and applying an appropriate voltage to the servo valve to control the pressure and achieve the desired peak pressure during the recoil cycle.

Abstract: A method of making cherries of the maraschino type is provided. Sulfite brined cherries are leached to reduce residual sulfur dioxide content to at most about 100 ppm. The leached cherries are then immersed in a sweetener syrup consisting essentially of high fructose corn syrup, solids from crystalline fructose, and a red coloring agent. The syrup has a sweetener solids content insufficient to cause substantial osmotic shock to said fruit, but said immersing raises the solids level of said cherry fruit and imparts thereto a red color. The use of the particular sweetener syrup allows the solids level of the fruit to be raised much faster than in conventional maraschino cherry manufacture and yet collapse of the fruit is avoided. Also provided is a method of packing frozen fruit.

Abstract: 1. Immunological method for the determination of free substances having hapten properties.2.1. Immunological methods for the determination of free substances having hapten properties, especially of free thyroid hormones, are based on various determination principles, all of which either have disadvantages from the practical viewpoint or, by reason of the basic principle of the method, provide limited information in marginal cases. The new method is intended to simplify and improve the routine clinical determination of free substances, because of the avoidance of sources of error associated with known methods, while having a procedure which is straightforward for practical use.2.2.

Abstract: Several embodiments of cylinder head and valve train configurations for an overhead valve internal combustion engine that permits increased valve area without interference and while maintaining simplified valve actuation. In each embodiment one pair of valves is operated by one cam shaft and lies on one side of a plane containing the axis of the cylinder. Three other valves are positioned primarily on the other side of the plane and reciprocate about axes that are not parallel with each other. These axes, however, intersect so that each of these three valves may be operated by the same cam shaft. In one embodiment of the invention the intersection of the valves axis is coincident with the axis of rotation of the respective cam shaft so as to permit direct actuation of the valves. In another embodiment the intersection lies substantially along a plane that intersects the stems of the valves when they are closed to facilitate operation of multiple valves from a single cam lobe by means of a single rocker arm.

Abstract: A blasting composition is disclosed having bulk density and hence explosive energy superior to that of conventional ammonium nitrate fuel oil mixtures, e.g. 94% AN, 6% fuel oil mixtures, but of nearly comparable cost. It comprises two major constituents blended together, namely, (1) about 10 to 40% by weight of a water in oil emulsion which includes aqueous solution of a powerful oxidizer salt as the disperse or inner phase and an oil serving to provide oxygen balance as the external or continuous phase, this emulsion being mixed or blended with (2) a mass of essentially solid particulate oxidizer salt in proportions of 60 to 90% of the total. The emulsion, which may be also a slurry, is mixed to partially but not completely fill the pores or interstices in the solid particulate mass, thereby to increase bulk density, part of the spaces being left unfilled to provide aeration and active sites or "hot spots" to facilitate detonation of the composition by standard detonation devices.

Abstract: A demountable tonneau cover for enclosing the open top of a pick-up truck cargo box comprises a relatively light-weight laminated panel which fits onto the open top of the cargo box to enclose the cargo space. Two pairs of spring-loaded pins are mounted on the interior of the cover along opposite sides for releasably latching the cover to the sides of the cargo box. These pins are inaccessible from the exterior of the cargo box when the cover is on the box. Cables extend from the spring-loaded pins through passages within the cover to pull handles which are also mounted on the interior of the cover adjacent the rear edge. The pins are normally biased to extended positions for fitting into holes in the sides of the cargo box and thereby latching the cover in place on the cargo box. When the pull handles are operated, the pins are retracted out of the holes thereby allowing the cover to be displaced from the position enclosing the cargo space.
