Title: Mechanical motion sensor

Abstract: MECHANICAL MOTION SENSOR                     ABSTRACT OF THE DISCLOSURE           There is disclosed a motion sensor which may be utilized for sensing rotary motion and incorporating a housing formed with a vertical barrel having pins projecting diametrically inwardly from the opposite sides thereof and terminating in spaced apart relationship.  Received telescopically in the barrel between the pins is a cylindrical float formed on its opposite sides with outwardly opening reliefs forming at their upper extremities downwardly concave arches for resting on the pins and each forming a pair of horizontally spaced apart flutes extending downwardly on opposite sides of a vertical rib which terminates at its upper extremity in an upwardly facing abutment surface aligned centrally below such arch for selective engagement with the pins as the float is telescoped upwardly in such barrel.  Consequently, the float will normally be suspended from the barrel by engagement of the arches with the pins to thus align such rib directly below the pins and upon raising of the float vertically up-wardly the abutment surfaces will engage such pins to limit further upward movement.  However, when the float is rotate in one direction or the other during its vertical upward travel the ribs will be rotated to one side of the pins thus allowing such pins to pass downwardly in the flutes to permit further upward travel of the float.

Abstract: SUPPORTED PLASMA SPUTTERING APPARATUS FOR HIGH DEPOSITION RATE OVER LARGE AREA                         Abstract A supported plasma sputtering apparatus is described having shaped electrical fields in the electron discharge region between the cathode and anode and the sputter region between the target and substrate while such regions are free of any externally applied magnetic field to provide a high deposition rate which is substantially uniform over a wide area.  Plasma shaping electrodes separate from the anode and target shape the electrical fields in the electron discharge region and the sputter region to provide a high density plasma.  The anode surrounds the target to cause substantially uniform sputtering over a large target area.  In one embodiment the anode is in the form of an annular ring surrounding a flat target surface, such anode being provided with a ribbed upper surface which shields portions of the anode from exposure to sputtered material to maintain the electron discharge for a long stable operation.  Several other embodiments accomplish the same result by using different anodes which either shield the anode from sputtered material, remove the sputtered coating on the anode by heating, or simultaneously mix sputtered metal from the auxiliary target with sputtered insulator from the main target so the resultant coating is conductive.          A radio frequency potential alone or together with a D.C. potential, may be applied to the target for a greater sputtering rate.

Abstract: ABSTRACT            A differential pressure relief valve formed of a housing having first and second chambers sealed from the atmosphere and separated by an annular diaphragm with the chambers and the annulus of the diaphragm traversed by a moveable sleeve. The first chamber communicates to a primary pressure source through a first channel in the housing and the second chamber communicates to a secondary pressure source through holes provided in the sleeve and then to a second channel in the housing. The end of the sleeve protruding from the second chamber is engageable with a seat in the housing. The arrangement is such that when the primary pressure exceeds the secondary pressure by a predetermined amount, the end of the sleeve protruding from the second chamber engages the seat but if the primary pressure does not exceed the sec-ondary pressure by the  predetermined amount, the end of the sleeve does not engage the seat, and fluid escapes from the source through the second channel and communicating sleeve, past the seat.
