Abstract: A proximity sensor assembly is molded with a connector support that extends from an outer side of a sensor housing and supports an electrical connector such that an axis of the electrical connector intersects at a fixed angle less than approximately 90 degrees a line tangential to the outer side from which the molded connector support extends. The orientation of the connector support helps facilitate mounting of the proximity sensor assembly to an actuator housing such that the axis of the electrical connector intersects a center line of the actuator housing at a fixed angle less than approximately 90 degrees and greater than approximately zero degrees. In this manner, two proximity sensor assemblies may be mounted relatively closer to one another at opposite ends of the actuator housing while shielding conductor cables mounted to the proximity sensor assemblies in a corridor or region between the proximity sensor assemblies.

Abstract: An excimer laser has a pair of main electrodes defining a lasing space, and a series of pairs of pre-ionization pins arranged alongside the main electrodes. These pins form preionization gaps for generating discharges that provide ultraviolet radiation to condition the gas in the lasing space. The invention consists of providing a tracker of insulating material between each pair of pins to bridge the gap and provide a tracking surface for the pre-ionization discharge.

Abstract: A proximity switch assembly is provided which has a base with a longitudinal axis. A sensing coil is mounted on the distal end of a probe on a front axial end of the base, and the base is adapted to be mounted to a machine which has a moving part, the position of which relative to the sensing coil is to be determined by the proximity switch. An electrical cable connector is rotatably mounted on the base and may be rotated into a plurality of positions around the axis. Conductors extend between the sensing coil and the electrical cable connector, and at least part are deformed spirally to permit rotation of the cable connector. A series of teeth are on the base and a locking spring moves into engagement with any of the teeth to establish the plurality of locked rotational positions.

Abstract: The apparatus includes a device adapted for removing contaminated air from a controlled area, cleansing this air using suitable filtration devices, and returning air having a safe level of contaminants mixed with a portion of fresh air or solely fresh air to the controlled area. The apparatus further includes barrier means for preventing contaminants from exiting the controlled area except through the air removal device which can be located either inside or outside of the controlled area.

Abstract: Electromagnetically operated contactor or relay in which the stationary magnetic core and operating coil are mounted in a base section and the movable armature and the switching elements are mounted in a main frame section. With the two sections assembled together the pole face structures of the stationary core abut reference surfaces in the main frame section. When the operating coil is energized, the armature moves into contact with the pole faces of the stationary core. Thus, since the reference surfaces in the main frame section determine the position of the stationary core pole faces and hence the position of the armature when the core is energized, the positions of all movable elements are determined solely by dimensions of the main frame section independently of the base section.

Abstract: A section of tubing having a sufficiently large diameter to accommodate several lengths of wire of the sort useful as a fishtape. The section of tubing is curved so as to form an arc of sufficient length such that the fishtape may be looped several times through the large-diameter tubing, providing a convenient storage therefor. The large-diameter tubing includes a short piece of small diameter tubing which is positioned on the inside wall of the large diameter tubing and which functions both as restraint for the projecting end of the fishtape and also as a guide for the fishtape as it is extended from the holder in operation.
