Abstract: A fluidless bottle testing method and apparatus are disclosed. After being subjected to a squeeze test for side wall strength, bottles are moved to a bottle bottom tester which places the outer surfaces of the bottom and of the lower side wall of the bottle into tension. Bottles which would fail in service due to thin or weak walls, checks and scratches fail during the test and are thus removed prior to filling. Preferably the apparatus for performing the bottom test supports the bottle at a large bead on the neck or annularly at the lower portion of the side wall. A test rod is lowered (or the bottle is raised) into the mouth of the bottle and ultimately against the central bottom of the bottle, creating a flexure stress in the bottle bottom. The test facilitates rapid 100% bottle testing without the application of pneumatic or hydrostatic pressure to the interior of the bottle.

Abstract: An article transferring device for exchanging workpieces between first and second paths is disclosed. The device utilizes vertical reciprocal movement and 180.degree. rotational movement to operate apparatus which grips workpieces traveling in the first path, raises them, transfers them to a position above the second path, lowers them into the second path and releases them. Cams responsive to vertical movement are provided for changing the spacing of each pair of workpiece grippers from a first spacing at the first path to a second spacing at the second path.

Abstract: A gas fired infrared heat generator having certain special features is disclosed. The device includes a dead man control valve within the fuel line operable from the handle and so arranged that, in conjunction with spacer means across the front of the reflector, the gas valve will close if the tool is dropped or left unattended on a surface. Multiple couplings are provided on the combustion chamber of the device for connecting the handle and gas line assembly to either the back of the combustion chamber for use of the heater in an upward direction or to one side of the combustion chamber for use on other surfaces.

Abstract: The invention relates to an electrostatic spray gun for the deposition of powdered coating material characterized by an improved deposition efficiency and provided with a multi-stage, trigger operated control that permits spraying at a plurality of conditions that may be preselected by the operator. An axially disposed needle charging electrode is used and an axial air flow passage surrounds the same to reduce any troublesome accumulation of powder on the needle under all spraying conditions.

Abstract: A swimsuit, particularly for women comprising a tight-fitting body having an elongated opening porous seam down the back, extending from the neck to adjacent the waist for the escape of air or water from inside the swimsuit.
