Filed:

Dec 4, 1985

Appl. No.:

6/805347

Inventors:

William Gorra - Bolton CT
Kenneth J. O'Neil - Manchester CT
Jeffrey S. Dawson - Granby CT

Assignee:

Syndet Products, Inc. - Manchester CT

International Classification:

B60S 304

US Classification:

134 57R

Abstract:

A vehicle washing system having apparatus for following the surface contour of a vehicle includes a redirectable directional discharge manifold assembly for a cleaning solution that is supported by an overhead, pivotally mounted boom at a washing station. Sensors mounted in the region of the manifold assembly sense the contour of the passing vehicle and a controller responsive to the sensor provides drive signals which activate a motor to move the boom and maintain the boom and manifold assembly at a predetermined distance relative to the vehicle as the vehicle passes the washing station.

Abstract:

A freeweight lifting exercise machine having a barbell connected to a cable system operated by a pneumatic motor supported below a lifting bench. An electropneumatic control system operated by a weightlifter using the machine controls the pneumatic motor to apply an exponentially variable lifting force to the cable in response to linear movement of a foot pedal to replicate the function of a "spotter". The control system automatically applies sufficient lifting force to the cable to remove slack from the cable during the lifting mode and nullifies the slack removing force during the lowering mode of a normal lifting exercise enabling the lifter to perform a freeweight lifting exercise free of machine influence.
