Abstract: A magnetically operated valve having a resilient flat-surfaced valve member cooperating with a valve seat is disclosed. The resilient member is preferably mounted on an armature in a manner to permit relative motion therebetween to allow the armature to gain a predetermined inertia prior to engaging the resilient member so as to aid in overcoming the pressure differential across the resilient member. Additionally, the electromagnet thereof acts unevenly on the armature so as to cause tilting movement thereof and a corresponding "prying" movement of the resilient member from the valve seat. The valve may be operated in the normally-opened or the normally-closed mode. In one embodiment, at least a portion of the armature is provided with a non-magnetic covering or coating, thereby forming a non-magnetic gap thereon. In another embodiment, a non-magnetic wear plate is disposed between at least a portion of the electromagnet and the armature.

Abstract: A file cabinet having drawers and doors and an anti-tip lock mechanism that simultaneously locks all closed doors and drawers when in a locking mode and that permits movement of a single drawer from its closed to its open position while simultaneously locking both the remaining unopened doors and all of the other drawers against movement from their closed to their open positions when in an unlocked mode.

Abstract: A pneumatic, piston/cylinder counterbalance in which the counterbalance force is obtained by differential pressure across the piston and in which the force changes due to temperature are compensated by use of a variable volume cylinder having one or more auxiliary chambers separated by walls, each including a temperature responsive bi-metal disc valve normally acting as a check valve permitting flow into the auxiliary chambers but preventing flow out of the chambers except when the temperature drops to a predetermined value. In the multiple auxiliary chamber embodiment, flow into and out from each chamber is controlled by an associated bi-metal disc valve responsive to successively lower temperatures to enable a more linear stabilization of force output regardless of temperature.

Abstract: Disclosed is a vacuum pump device that is adapted to create a vacuum source from a source of high pressure air. The device comprises a piston actuated in one direction by compressed air and in the opposite direction by a power return spring. The compressed air moves the piston to load the spring and the spring moves the piston to create a vacuum. A special dumping valve is also provided which is actuated toward the end of the return stroke of the piston to cause a sudden increase in the pressure differential across the piston to prevent stalling of the piston when loading is such that the piston moves very slowly, thereby assuring that the vacuum pump will cycle as often as is necessary to maintain the desired vacuum.
