Abstract: A non-contact type coaxial switch that eliminates all contacts and inner conductors. The switch includes a stator/coax base assembly and a rotor. The stator/coax base assembly is fixed, while the rotor is rotatably mounted to the stator/coax base assembly and eliminates all contacts and inner conductors. The rotor is disposed between bearings, and consists of waveguide paths that couple between selected coax connectors. When the rotor is rotated, different selected coax connectors occur. For other arrangements selected, the rotor can switch between a condition of coax and waveguide outputs. The rotor, between bearings, consists of waveguide paths which couple between selected coax connectors. When the rotor is rotated, a different selected coax connector occurs. For other arrangements selected, the rotor can switch between a combination of coax and waveguide outputs. The switch can assume many configurations.

Abstract: A shampoo bowl is provided for shampooing a person's hair. The shampoo bowl includes a lower basin. The bottom of the lower basin has a drain toward the rear of the lower basin, a face opening toward the front of the lower basin, and a face cradle gasket surrounding the face-opening. The lower basin is deeper at the rear than at the front of the lower basin, and the front of the lower basin is lower than the rear of the lower basin. A shampooing cape is attachable to the front of the shampoo bowl.

Abstract: A self-latching sector motor for producing a net torque from two integral independent sources where one can serve as a spare backup or paralleled for double net torque or used alternately for extended life operation. The self-latching sector motor includes a housing, a magnet-shaft assembly, and two pair of electromagnetic poles. The magnet-shaft assembly rotates within the housing. The two pair of electromagnetic poles extend fixedly and radially inwardly from the housing, towards the magnet-shaft assembly. The electromagnetic poles of an associated pair of electromagnetic poles are diametrically and magnetically opposed to each other, and each pair of electromagnetic poles are similarly poled to each other for North and South poles so as to provide the net torque to the magnet-shaft assembly that can be backed-up or doubled. The self-latching torque at the stops is achieved by restraining the magnet-shaft assembly from seeking a position of maximum flux.

Abstract: A linear solenoid includes a pair of soft iron pole members which are in a spaced apart linear arrangement. A permanent magnet is attached to the end of a plunger which rides between the pole members. When a first of two electro-magnet coils is energized the plunger which is latched to one of the pole members is repelled to the opposite pole member and latched. When the second coil is energized the plunger returns to the original pole member and is latched.

In a first embodiment, a first electrode is provided with a second electrode disposed adjacent to the first electrode, and defining a gap therebetween. A photo-radiation emission layer is disposed in the gap. The photo-radiation emission layer includes a charge-transport matrix material and an emissive particulate dispersed within the charge-transport matrix material. The emissive particulate receives electrical energy through the charge-transport matrix material applied as a voltage to the first electrode and the second electrode photo-radiation. The emissive particulate generates photo-radiation in response to the applied voltage. This photo-radiation is effective for the selective polymerization of photo-radiation curable organic material.
