  • Patent number: 5048851
    Abstract: An apparatus for use particularly by joggers to prevent unnecessary impacting to a jogger's knees during a downhill traverse in a jogging event. The apparatus is defined as a plurality of "U" shaped framework members arranged for interfitting relative to one another. The framework members are each separable to accommodate positioning about an individual's anatomy and are securable to the anatomy during periods of transport by a plurality of fabric straps securable together by hook and loop fasteners. An inflatable bladder is positioned adjacent each base of each respective "U" shaped framework to resiliently accommodate and cushion mounting to a torso or arm portion of an anatomy of an individual jogger during their transport prior to use.

  • Patent number: 5042602
    Abstract: A loader includes a liquid-cooled internal combustion engine, a radiator for cooling an engine cooling liquid, a cooling fan and a radiator for cooling a working oil all of which are accommodated within an engine room. One of both the radiators is so disposed as to face a rear maintenance opening of the engine room, and the other radiator is so disposed as to face an upper maintenance opening of the engine room. Cooling air is sucked from an air-induction port of an upper cover member and is discharged from an air-discharge port of a rear cover member after passing through the other radiator, the cooling fan, the one radiator in order.

  • Patent number: 5040809
    Abstract: A portable folding cart can be collapsed into a compact storage assembly. The base of the cart is a generally rectangular platform for supporting items to be transported. A plurality of wheels are mounted to the underside of the platform. The platform has a right side member and left side member, each of the side members being pivotally foldable at a joint along the length of the side member. A plurality of cross braces join the side members to each other, each cross brace also being pivotally foldable at a joint along the length of the cross brace. At the pivot hinge of each cross member, a spring is provided to bias the cross brace into its open position. A handle is attached to the platform and the handle has a pair of upright members, each having a plurality of telescoping segments. The right side upright member is pivotally attached to the right side member of the platform and the left side upright member is pivotally attached to the left side member of the platform.

  • Patent number: 5038886
    Abstract: The status of a lock-up clutch included in an automotive power unit T/C is monitored. In the event that the lock-up clutch is partially locked up or conditioned to produce so called "slip lock-up", ERF (electroheopectic fluid) filled engine mounts are conditioned to produce an increased amount of rigidity, while in the event that the lock-up clutch is fully engaged the engine mounts are induced to assume a more flexible state.In addition to this engine idling and shake, vibration can be attenuated by sensing the relative displacement between the power unit and the chassis.

  • Patent number: 5000277
    Abstract: A hydrostatic steering arrangement and control having the high speed steering capability of an output-driven system and the low speed steering capability of an input-driven system. The engine drives the vehicle through a fluid coupling and a multiple ratio hydraulic transmission, and the hydrostatic pump of the steering system is driven by the output (turbine) of the fluid coupling. Increased steering capability at vehicle speeds which would otherwise limit the steering capability, is achieved by controllably slipping the active torque transmitting device of the transmission. In this mode, the hydrostatic pump speed is permitted to increase, and the steering system operates essentially as though it were input-driven.

  • Patent number: 4995629
    Abstract: A boat latching device for securing the hull of a boat to a trailer having a bow stop bar includes a latch-catch member having a recess for receiving the bow stop bar, the latch-catch member being mounted onto the hull of the boat. The latching device also includes an overcenter pawl member having a plurality of cam surfaces which cooperate with a resilient spring. The resilient spring holds the pawl member in a locking position in which the bow stop bar is retained within the recess and in an unlocking position for permitting the release of the bow stop bar from the recess.
