Abstract: A method is described for a dissolving crystals formed in a side reaction to an oxidation-reduction reaction. A low frequency substantially square wave signal less than 10 kilohertz is applied across the battery terminals to dissolve unwanted crystals.

Abstract: A vehicle seat suspension includes a bottom frame adapted to be mounted on the vehicle and a top frame located above the bottom frame and adapted to support a seat thereon. A substantially fully collapsible scissors linkage is interconnected between the bottom frame and the top frame enabling the bottom frame and the top frame to move relative to each other substantially in parallelism. A biasing arrangement is disposed between the top frame and the bottom frame and has a preload force urging the top frame away from the bottom frame. A first adjustment mechanism is located in the top frame and selectively enables fore and aft adjustment of the top frame relative to the bottom frame.

Abstract: A vehicle suspension system particularly useful in the heavy duty truck and trailer industry is disclosed. The suspension features lower control rods that are pivotally connected at their leading ends to hangers attached to each side frame member. The rearward ends of the lower control rods are attached to axle seats, one at each end of the axle, which are connected to the axle of the vehicle. Air springs and shock absorbers or, alternatively, hydraulic cylinders with accumulators, are mounted between each axle seat and each side frame member. The lower control rods are in an inclined orientation with their forward ends above their trailing ends. Additionally, some embodiments of the suspension feature upper control rods with their forward ends pivotally attached to the two opposing truck side frame members. The rearward ends of the upper control rods are attached to the top center of the axle by either a bolt and bushing mount or a ball and socket mount so that the upper control rods form a "V".

Abstract: A two-way valve for introducing pressurized air into the air chamber of an air shock absorber, and for maintaining a preselected minimum pressure within the air chamber. The valve includes a valve body and a valve cover mounted thereon. The valve body has an orifice in communication with the air chamber, and the valve cover has a fluid port in communication with a source of pressurized air. The valve cover includes a downwardly extending exhaust seat which surrounds the fluid port. Disposed within a recessed chamber in the valve body are an armature, an elastomeric diaphragm mounted on and supported by the armature, and a spring arrangement operatively positioned between the armature and the floor of the recessed chamber.

Abstract: The present invention relates to a suspension means for supporting the cab of a truck cab on a truck chassis frame. More particularly, it relates to a means of fine tuning the frequency response of the spring mass system to isolate all of the modes of the frame and still control hard jounces. The suspension includes air springs, an air reservoir, an hydraulic shock absorber, and height control valve. An air reservoir serves to lower the spring rate of the air spring, and an orifice causes nonlinear air damping of the system.

Abstract: A device for protecting a tarpaulin from damage, as it passes over the sharp corner of a load, which is mounted on a flat bed truck, or other transporting device. The protective device comprises three planar sides and a rounded corner, it is inserted between the load and the tarpaulin, at the corner of the load, and prevents direct bearing of the tarpaulin upon the sharp corner of the load.
