Abstract: A fitting assembly for coupling a tubular member to mechanical devices, such as valves or cylinders is disclosed wherein the fitting includes a body member having therein a passageway communicating with the tube, and a plurality of bores of increasing diameters in which a sealing ring in one bore is held in position by a retaining ring in another bore, and a retainer member in said other bore holds the sealing ring and retaining ring in place. The retaining ring holds the tube against inadvertant removal by having an inner diameter thereof in gripping engagement with the outer surface of the tube.

Abstract: A washer cutting machine is disclosed wherein a sleeve of an elastomeric material suitable for use as a washer is placed on a mandrel and rotated. A predetermined length of the sleeve extends beyond the end of the mandrel, and a knife-edge moves in a radial direction to cut a ring from the end of the sleeve of a width such that it may be suitable for use as a washer. The machine is programmed so that the steps of loading the sleeve on the mandrel, cutting a washer from the sleeve, advancing the sleeve the width of a washer to be cut at the completion of each cutting operation, and stopping operation of the machine after the last washer has been cut therefrom, are all carried out automatically.

Abstract: A programmer includes an intermittently rotating drum, having thereon a series of actuators arranged in a pre-selected manner, for actuating in a predetermined order, a plurality of devices, such as fluid valves, each of which, when actuated, causes an operation to be performed. The drum is indexed by a stepping motor controlled by impulses of energy to a pilot valve in response to rotation of the drum. The actuators are removably mounted on the drum, so that the programming of the series of operations as to the order thereof, and duration of each, can be done quickly and easily, in advance. Individual valves can also be shut off when not needed.
