Abstract: The invention is a carrier for use in air dropping cargo from an aircraft, the carrier comprising a pallet suspended from a parachute. The pallet has struts which absorb shock and prevent cargo roll over when the pallet lands, the struts being deployed into a shock absorbing, anti-roll-over position by the drag of the parachute when it opens. The pallet includes shock absorbing supports between its upper and lower surfaces to further protect air dropped cargo upon landing.

Abstract: A pre-existing trailer is modified to increase its payload capacity from approximately 50 tons to approximately 60 tons. Modifications involve the addition of one new axle, and the remounting of existing wheels to make them steerable. The modified trailer has one fixed axis axle and four steerable axles (two in front of the fixed axis axle, and two behind the fixed axis axle). During turning maneuvers the ground wheels on the fixed axis axle turn freely without skidding because the other steerable wheels automatically turn into the direction of steer. The modified trailer operates with lessened skid force on the wheels, with resultant increases in tire life and axle life.

Abstract: The invention is a mechanism for removing a liquid such as oil or transmission fluid from an enclosed cavity of a motor vehicle. The invention includes a tube slidable through the sealing plug of the compartment and a flexible bladder into which one end of the tube can be fit. A shut-off valve in the tube controls the flow of liquid from the compartment to the bladder. The invention optionally includes a simple hand operated pump in the tube and a device to prevent the tube from unintentionally being removed from the plug.

Abstract: The invention is vehicle propulsion system having a pump driven by an engine, a hydraulic motor driven by the pump, and a ground engaging wheel driven by the hydraulic motor. On the drive shaft connected between the engine and the pump is a flywheel whose moment of inertia is varied by radially translating weights on the flywheel. Under normal vehicle operating conditions, the weights are translated outward, whereby rotational energy is stored in the flywheel. When more power is needed then the engine can provide, the weights on the flywheel translate inwardly so that the flywheel imparts rotational energy to the pump through the drive shaft. The propulsion system has means to maintain the engine in a narrow r.p.m. range where the engine is most efficient. Vehicle speed and direction is varied by controlling the flow speed and direction from the pump, which determines the speed and direction of the hydraulic motor. The system also has an override mode wherein the engine speed is set at a new, higher level when a foot pedal operated by the vehicle operator exceeds a given range of movement.

Abstract translation: 本发明是具有由发动机驱动的泵，由泵驱动的液压马达和由液压马达驱动的地面接合轮的车辆推进系统。 在连接在发动机和泵之间的驱动轴上是飞轮，其惯性矩通过在飞轮上径向平移重物而变化。 在正常的车辆操作条件下，重物向外翻转，由此旋转能量储存在飞轮中。 当需要更多功率时，发动机可以提供飞轮上的重物向内平移，使得飞轮通过驱动轴向泵提供旋转能量。 推进系统具有将发动机维持在较窄的r.p.m。 发动机效率最高的范围。 通过控制来自泵的流速和方向来改变车速和方向，这决定了液压马达的速度和方向。 该系统还具有超车模式，其中当由车辆驾驶员操作的脚踏板超过给定的移动范围时，发动机速度被设定在新的较高水平。

Abstract: A method of forming a foamed plastic article, comprising the steps of: injecting pressurized gaseous bubbles into a stream of heated liquid plastic; feeding the heated liquid, with entrained gas bubbles, into a mold cavity without expanding the bubbles; slowly expanding the mold cavity to permit the gas bubbles to expand and thereby produce a foamed plastic article; controlling the temperature of the mold cavity surfaces so that the plastic material is in a viscous liquid state during at least the major part of the bubble expansion process; and cooling the mold cavity surfaces to a temperature less than the melt point of the plastic.
