Abstract: ABSTRACT OF THE DISCLOSURE An automatic switch comprised of a dual-contact switch mechanism, a bimetallic thermostatic element, a solenoid-type tripping device, and an arc chamber complete with deionization plates.  To eliminate one of the three elec-trical-hook-up steps (one, the physical attachment to a mount-ing, and the two electrical terminal connections), a group of components is provided for the switch assembly, including a plug-like terminal, which forms one end of the switch's elec-trical terminals on the rear housing wall, and an additional snap-action holding element disposed at the distal part of the rear housing wall from said plug-like terminal.  The automatic switch incorporating these components can thus be snap-mounted onto a conductor rail by means of said plug terminal and onto a separate non-conductive mounting bar or rail - all in a single step.  The remaining conductor can be wired-up in the traditional way thereby placing this switch in a circuit by only a two-step procedure.

Abstract: INSPECTING AND SORTING OF GLASS CONTAINERS               Abstract of the Disclosure A method and apparatus for inspecting and sorting transparent containers such as glass containers having defects in the container sidewalls, and for distinguishing between commercially acceptable and unacceptable defects on the basis of defect type and size.  A light source is positioned to direct diffused illumination through the sidewall of a container under inspection as the container is rotated about its central axis with the intensity of the illumination varying across the light source transversely of such axis as a pre-determined function of transverse position.  In specific dis-closed embodiments of the invention, the light intensity is filtered across the source to provide transversely spaced outer regions of uniform intensities, either equal or unequal, and an intermediate region of either uniform intensity different from that in the outer regions or transversely varying intensity.          A camera which includes a plurality of light sensitive elements disposed in a linear array parallel to the axis of container rotation is positioned to receive light energy transmitted through the container sidewall.  Electronics monitor the camera light elements during container rotation, identifies defects as a function of differences in light detected by the camera elements at adjacent increments of container rotation, and generates signals to distinguish and sort defective containers from commercially acceptable containers.  A conveyor sequentially presents containers for inspection and includes separate selec-table exit paths for acceptable and unacceptable containers.

Abstract: ABSTRACT OF THE INVENTION:           On a machine for welding together the longitudinal edges of rounded sheet-metal container body blanks there are disposed a plurality of rings of rollers round a common longitudinal axis, one behind the other in the direction of a passage through of the blanks.  At least some of the rol-lers of the rings of rollers are each mounted on a roller carrier which is adjustable in the direction away from the longitudinal axis against resilient resistance.  The roller carriers are guided in a manner which enables the associated rollers to execute yielding movements at an angle of dis-tinctly less than 90° to the direction of the passage through of the blanks.  For this purpose, the roller carriers are each pivotable about a transverse pin which is disposed at least substantially parallel to the associated roller spin-dle, upstream of this with respect to the direction of the passage through of the blanks.  This guiding of the roller carriers makes an important contribution to avoiding damage to the leading edges of the blanks and to reducing the noise occurring when these leading edges impinge on the rollers.
