Abstract: A gear availability indicator for multi-gear transmissions of motor vehicles includes a signal processing unit for receiving input signals representative of vehicle speed and engine speed. The signal processing unit can determine a gear ratio value representative of the relationship between vehicle speed and engine speed for each gear in the vehicle transmission and can generate output signals for operation of a display. The display includes a first section displaying a range of acceptable engine speeds and a second section displaying gear symbols representative of gear ratio values. The displayed range of acceptable engine speeds and the displayed gear symbols are relatively moveable. The mutual alignment of the displayed range of acceptable engine speeds and one or more of the displayed gear symbols indicates that one or more gears represented by the one or more gear symbols are available for engagement in the transmission.

Weep holes (62), (104), (102), and (100) in a sleeve (50) of an push rod (18), in a spring brake actuator rod (84), and in a spring brake housing portion (68) together permit fluid compressed in a first service brake chamber (30) to flow through a conduit define by these weep holes out of the brake actuator (10) wherein it is filtered by the filter assembly (134).

Abstract: The invention relates to a water extraction cleaning machine having a variable solution mixing valve adapted to create cleaning solution mixtures of variable constituent ratios. Clean water and detergent are provided from tanks supported on the water extraction cleaning machines. The size of the detergent inlet opening can be altered through rotation of a control knob provided on the outside of the water extraction cleaning machine. The knob is interconnected to at least one member which is adapted to vary the size of one of the detergent fluid inlet and the clean water inlet so that the ratio of constituent elements can be altered depending upon the cleaning application.

Abstract: The invention relates to a device for performing contouring operations on a three-dimensional member, such as boat hulls, decks and molds. The device comprises a first frame and a second frame wherein the second frame is movably mounted to the first frame. A robotic arm is movably mounted to the second frame whereby a distal end of the arm is positionable in three dimensions with respect to the member. The distal end of the arm is adapted to carry a tool thereon. The structure of the first frame defines a pair of working chambers therein and a passageway so that the arm can travel therebetween. A controller is interconnected to the arm and the first and second frames for controlling the position of the second frame with respect to the first frame, the arm with respect to the second frame, and the distal end of the arm with respect to the arm. The tool on the arm can thereby be positioned to abut the member and perform contouring operations thereon.

Abstract: A suspension system for a vehicle includes a longitudinally extending frame, an axle connected to the frame for relative movement with respect thereto, an air spring mounted between the frame and the axle to yieldably support the axle with respect to the frame, and upper and lower trailing arms attached to each side of the frame. A first torsion bar extends between and is rigidly attached to the upper trailing arms and a second torsion bar extends between and is rigidly attached to the lower trailing arms. The torsion bar cooperates with the springs during deflection of the suspension system with respect to the frame to thereby yieldably resist relative movement between the trailing arms and the frame. In one embodiment, the upper and lower trailing arms are parallel to each other. This arrangement results in load equalization between the suspension assemblies. Any relative torque caused by deflection of the trailing arms is equally distributed between both torque bars.
