Abstract: A support for holding a loudspeaker in an elevated and tilted position is provided. The support includes a pivotable X-shaped frame formed of two legs pivotally connected together at a point equidistant from their respective bottom ends with the upper portions of said legs being of unequal length. The short leg has its upper portion facing forwardly and its lower portion rearwardly. Each leg has an arm and a foot perpendicularly secured to its top and its bottom, respectively. The upper end of the longer leg is bent forwardly at a point located approximately 1/4 to 1/3 of the distance from the pivot point to the top of the leg at an angle between about 20.degree. and 45.degree.. The forwardmost arm is lower than the rearward arm and is adapted to support the bottom of a loudspeaker while the upper arm is adapted to support rear of the speaker in a backwardly tilted orientation.

Abstract: An electrical circuit device having a ceramic substrate including a thick or thin film circuit on at least one surface thereof and an intersecting edge surface which may support termination leads anchored thereto and further retained by solder deposited upon an edge termination coating. The termination coating underlying the solder extends over the edge defined by the intersecting surfaces. The component resides in form of the substrate to include an indented area in the form of a notch or a groove which intersects both adjoining surfaces to provide a means of receiving edge termination material, so as to insure a continuous and non-interrupted deposit of the material to complete the electrical circuit between the leads and the respective circuit components of the circuit defined on the said one substrate surface.

Abstract: An electrical circuit device having a substrate including circuit components on at least one side thereof and a plurality of through openings in the substrate. Terminal leads are positioned in the openings each with a deformation intermediate the ends of the leads and spaced internally of the opening from a soldered area at the juncture of the exposed portion of the leads and the termination edge of the substrate. Two methods of assembly of leads to the substrate are also disclosed.

Abstract: A manned welding and inspection vehicle for working within the interior of a pipeline or the like, the vehicle including two annular seals for aligning the vehicle in the pipeline and for sealing portions of the environment about the vehicle. The vehicle also includes an automatic welding system, the welding head of which is located in the front end of the vehicle and capable of welding a 360.degree. arc. The welding head also includes a fine adjustment mechanism to compensate for misalignments. Driven by the engine of the vehicle is a driving mechanism which is rugged and compact, and a fan for creating the proper air flow around the vehicle without disturbing the air flow at the welding site.
