Appl. No.:

5/923967

International Classification:

H02G 1100

US Classification:

191 122R

Abstract:

A cable winding system carried by a vehicle for extending and retracting cable responsive to vehicle movement. The cable frictionally engages a controllably powered sheave and is guided into a horizontally disposed coil by a cylindrical guide arm having a vertically directed opening adjacent the sheave and a downwardly, radially and circumferentially directed opening adjacent the coil. The guide arm is freely rotatable about a vertical axis so that as cable is extended and retracted the guide arm rotates to guide the cable between the coil and sheave. The powered sheave directs cable from the vehicle through an instrumented fairlead which, through a control system, controls the operation of the sheave. The fairlead is pivotally mounted about a horizontal pivot axis so that the head pivots in one direction as the cable is tensioned and in the opposite direction as the cable tension is relieved. The control system measures the angle of the fairlead and may also measure the vehicle speed to cause the sheave to extend cable as the fairlead moves rearwardly and/or the velocity of the forward vehicle is increased and to retract cable as the fairlead moves forwardly and/or the forward velocity of the vehicle is reduced.

International Classification:

F01M 104

US Classification:

184 66

Abstract:

A lubrication system for an air motor which incorporates a positive feed oil pump, driven by the air motor, which forces lubricant, under pressure to the majority of critical lubrication zones. Because of manufacturing tolerances as well as ease of maintenance, the rotary valve and the main crankshaft are coaxial but separate. The lubricant is forced inwardly to the axis of either the crankshaft or the rotary valve and then transmitted to the other rotating member by way of a hollow elastic snubber which preloads the valve and crankshaft in opposite directions.

Abstract:

A workcell for making parts in a vertical orientation from rigid sheet material capable of self-support on edge includes a plurality of CNC machines for performing machining operations on said sheet material in a vertical orientation. The CNC machines receive machine control data from a cell controller which, in turn, receives nest order packages from a factory system. The parts data from which the factory system constructs the nest order packages comes from the original engineering parts definition in a central data storage system which is the ultimate parts design authority of the assembly for which the parts are to be made. The rigid sheet material is transferred in a vertical orientation to and between the CNC machines in at least one automated handling cart. The cart has a transfer mechanism for transferring sheets of the rigid sheet material on edge between the cart and the CNC machines. A motive mechanism is provided for driving the cart between the CNC machines under control of the cell controller, and for stopping the cart with its transfer mechanism in registry with the CNC machines.
