Abstract: Disclosed is a utility trailer having one or more stabilizers attached thto. The stabilizer is comprised of a pair of flat arms pivoted to the trailer and extending away therefrom, the arms defining holes disposed one above the other. A stanchion is vertically translatable through the holes in the arms and a spring in tension is stretched between the free end of the arms, whereby the free ends are biased toward each other and the edges of the arm holes bind against the stanchion to hold it in position. The arms may be pivoted away from each other to free the stanchion from the edges of the arm holes so as to allow the stanchion to be vertically translated to a new position relative to the trailer. A ground engaging foot is connected to the lower end of the stanchion.

Abstract: Armor panels are bolted to the outer walls of a military vehicle. Anti-theft collars are welded to the outer faces of the panels in surrounding relation to the bolt heads, to prevent unauthorized unscrewing or unloosening of the bolts.

Abstract: A two part, over center buckle for belting. The buckle has a retention member on one part of the buckle which will engage a detent on the second part of the buckle when the buckle is closed. The retention member holds the buckle closed against normal vibration and jarring.

Abstract: In association with a vehicle designed to carry a heavy load module, an ioved means for accurately guiding the module onto the vehicle bed surface as the module is being lowered into position. The improved guide comprises a plural number of specially formed nuts carried on the studs that are used to fasten the module to the bed surface. Each specially formed nut has a conical external surface that acts to center the module fastener holes relative to the axis of each associated stud. The improved guide provides a low cost mechanism for facilitating the quick alignment of a heavy cumbersome load module during the process of lowering the module onto a vehicle bed surface.

Abstract: In a flat bed cargo vehicle having a series of upwardly-opening pockets spaced therealong, and cargo tie-down anchor members swingably disposed therein: the improvement wherein each pocket has a porous bottom wall permitting water to drain out of the pocket; each said bottom wall comprising a series of baffles preventing flames in the zone beneath the pocket from travelling directly upwardly through the pores defined by the baffles, to detonate ammunition located on the bed.

Abstract: A military tank is equipped with an armored box structure in the space nolly occupied by the gun turret. A lid on the box structure is raisable to an inclined position suitable for the firing of a missile carried on the lid undersurface. As the missile is fired an explosive-charged line attached to the missile rear end is drawn out of the box structure onto the terrain (along the missile line-of-flight). By exploding the line charges it is possible to detonate enemy land mines in the vicinity of the charged line.

Abstract: A compressed air passage system carried by an axle on a road vehicle for nsferring compressed air from/to a central air pressure source to/from the associated vehicle wheel. The passage system comprises a specially-constructed duct installable in a clearance space between the axle housing and axle; an air transfer slip ring mechanism is arranged at the outer end of the duct to transfer compressed air across the interface between the non-rotating and rotating parts of the axle assembly. The system is specially designed to permit the air passage system to be added to a pre-existing axle construction with minimum modification of existing components.

Abstract: A turbine wheel for a hot gas turbine engine operable at relatively high peratures, e.g. above 2,000.degree. F., and high velocities, e.g. above 30,000 r.p.m. The blades are formed of temperature-resistant ceramic material. A special annular band of high tensile strength material is affixed to tip areas of the blades for translating centrifugal forces into compressive loadings on the blades. To compensate for differential thermal expansion of the band relative to the blades a localized cooling system is provided for selectively cooling the annular band without cooling the blades.

Abstract: An improved I beam construction for longitudinal I beams preferably as used n trailer frames. The I beam is comprised of a top flange, a bottom flange, a vertical web wall interconnecting the top and bottom flanges along their centerlines in a customary manner, for a substantial part of its length, with the novel aspect including a portion of the vertical web wall offset laterally toward the outer side edges of the top and bottom flanges so that said offset wall portion is essentially flush with those said edges. The purpose of this offsetting is to provide more advantageous horizontal and vertical mounting surfaces for saddle mount capability and attachment of a trailer's wheel suspension assembly, which construction is found to be stronger than can otherwise be fabricated.

Abstract: Mechanism for draining an engine oil filter cartridge when the space bene the cartride is otherwise obstructed. A special housing is threadably connected to the filter base in a non-obstructed location. A drain plug within this housing is manually unthreaded during a drain operation. A special boot in the mouth opening of the housing permits external actuation of the plug without undesired splash-out of oil through the mouth opening.
