Abstract: The device uses an elastic tubular bladder for receiving liquid which is expandable radially generally spherically at a local segment until a fully-expanded cross-section is achieved at which time the expanded region begins to grows axially, thereby maintaining a relatively constant pressure independent of bladder volume. The device is provided with a nozzle and a valve for controlling and directing the flow of the projected liquid.

Abstract: An adjustable pedal assembly for a vehicle having foot pedals which are shiftable longitudinally to vary the distances between the pedals and the driver. The pedal assembly is made up of a frame, one or more rotatable pedals fixed to the frame, and a power transmission device coupled to the frame and to the pedals for providing an output in response to pedal rotation.

Abstract: A motor-driven miniature vehicle having a wheel base less than or equal to its track, a pair of steerable front wheels and a pair of rear wheels, at least one of which is driven. The vehicle has positive camber and sufficient torsional stiffness and wheel radial spring rate so that the inside rear wheel is lifted completely off the ground in a turning maneuver. The vehicle being further provided with an engine drive train and mounting system which employs two centrifugal clutches, one having a low abrupt engagement and disengagement and the other having a gradual higher speed engagement and disengagement.

Abstract: A steering system for a vehicle having a pair of levers pivotably affixed to the chassis connecting the output of the steering gear mechanism, to tie rods which connect to the wheel assembly steering input. The steering system minimizes the space required for steering linkage.

Abstract: Foot pods in a vehicle having a seated occupant which provide a footrest for various size people without necessitating the movement of the seat. The foot pods are made of a series of transverse V-shaped grooves generally perpendicular to the occupant's leg which are formed in a recess in the body of the vehicle.

Abstract: An apparatus having a pair of brackets for attachment to the feet of the patient which are interconnected by a number of links pivotably attached to the shoe brackets. The shoe brackets are maintained in constant parallel spaced apart relation preventing transverse movement and relative rotation of the patient's feet about the vertical and longitudinal axis. The patient's feet may freely move relative to one another along the longitudinal and vertical axis as well as rotate about the transverse axis.

Abstract: The drive establishing mechanisms of a multigear ratio transmission are actuated according to a predetermined schedule with an electronically operated two member valve mechanism. Gear shifting is effected by producing relative movement between the valve members and a pair of electrically regulated fluid pressure mechanisms which control the fluid supply and exhaust pressures for all of the drive establishing mechanisms.
