Abstract: A damper arrangement is described which provides for selective separation of the insulator compartments from the main body of a wet electrostatic precipitator (WESP), permitting maintenance to be performed on the insulator in the compartment while process gas continues to flow through the WESP.

Abstract: A method is disclosed for providing an optical quality aspheric surface f a thin film metalized elastic membrane by treating the membrane with x-rays to cause the elasticity of the membrane to be increased in predetermined area so that when the membrane is subjected to a differential pressure across faces thereof the membrane will assume the desired aspheric surface.

Abstract: A wire resistor is mounted so that its position may be rotated continuously. The resistance of the wire (when subjected to the high energy laser beam) is measured as a function of position by use of a bridge circuit for determining the resistance and a potentiometer for determining the position. This device may also be used to analyze moderate power (greater than 1 watt) cw laser beams but here it is necessary to chop the beam in order to obtain the data.

Abstract: The invention contemplates a single-piece clippings retainer having snap-action assembly to a conventional nail clipper, of the variety in which elongate jaw members are connected at one end and diverge toward their other end. The single-piece retainer comprises a mounted end and an actuable end, with an integrally formed hinge connection therebetween. The actuable end has side panels to effectively close the sides of the space between jaw members when releasably retained in its "up" position; when the actuable end is released and downwardly hinged, the open sides of the space between jaw members is exposed, and accumulated clippings can be discharged under control, i.e., without scatter.

Abstract: The laser light is polarized and sent through an electro-optic pockels cell here it is phased shifted in a duty cycle in accordance with the amplitude intensity. The light is then sent through an analyzer which will act as an attenuator to regulate the final amplitude output of the light.
