Abstract: For connecting a high voltage wire to an elongated terminal of an electrical device, a connector link is provided comprising a first hollow tubing having an open first end with an extending flattened portion of the tubing bent to form the wall of a second hollow tubing having an axis of elongation perpendicular to the axis of elongation of the first tubing. The second hollow tubing is interference fitted onto the terminal and an end of the high voltage wire is inserted into the open end of the first tubing. The wire end is soldered to the first tubing and the second tubing is soldered to the terminal. An abundance of solder is used for causing the solder to flow outwardly from the ends of the tubings to form a continuous well-wetted shape of solder having smooth and rounded surfaces for avoiding concentrated electric fields and attendant electrical discharges.

Abstract: Disclosed is a particle sensor of the type having (a) a light beam, (b) an air tube flowing a stream of air across the light beam at a volumetric flow rate, and (c) an air pump providing the stream of air through the tube, across the light beam and along an air flow path. In the improvement, the particle sensor includes a flow-controlling apparatus in series with the flow path for slightly trimming or adjusting the flow rate, i.e., the rate usually set at the factory before shipping. Such flow-controlling apparatus is selected from a group of apparatus including a choke valve (preferably an adjustable choke valve), a slip clutch, a speed-adjustable blower drive motor and a plurality of conduits. The conduits may have the same passage cross-sectional area and differing lengths, the same length and differing cross-sectional area or a combination of such conduits. A new method for assaying an airborne particle is also disclosed.

Abstract: The new particle sensor is used for assaying particles and includes a light source comprising one or a plurality of light-emitting laser diodes. Light from each diode propagates along a flexible conduit or "light pipe," preferably a separate fiber optic strand. The sensor has a low voltage power supply and drives the diodes at 1-5 VDC. Light from one or bundled fiber optic strand(s) is focused by a focusing lens to provide an intense light beam for small-particle detection. For improved design flexibility, the light source may be mounted independently of the light beam long axis.

Abstract: Disclosed is a particle sensor having a light beam with a beam long axis and an air flow tube with an inlet end and a particle exit mouth. In an aspect of the invention, the cross-sectional area of the flow passage at the inlet end is greater than the cross-sectional area of the exit mouth. This enlarged area dramatically reduces pressure drop along the tube. The exit mouth is in registry with the light beam and is elongate in a direction substantially parallel to the beam long axis. Thus, particles flowing through the mouth pass through the beam. In another aspect, the invention includes a centrifugal blower which is light in weight and which may be battery powered.
