Abstract: This invention is an improved apparatus for detecting residue that is left on a core rod of injection blow molding apparatus after blown articles have been stripped from the core rods at a pick-off station, and before the core rods are delivered to an injection station. The detecting apparatus moves in a straight line across a row of core rods extending from the face of an indexing head and while the core rods are stationary.

Abstract: This specification describes a fiber optic cable in which the delicate glass fibers are supported by carriers which protect the fibers from stresses imposed during the manufacturing process, the installation of the cable and the environmental conditions after installation. Microbending of the fibers is eliminated by having smooth supports and by protecting the fibers from contact with any structure that will stress them. Another feature is the provision of tension elements in the carriers with neutral axes in transverse alignment with the neutral axes of the glass fibers that the carriers support.

Abstract: This cord connector for printed wiring cards is self-latching to the printed wiring card so that the conventional hold down screws are no longer necessary. The shell halves that protect the connector contacts are interlocking to facilitate the original assembly of the connector.

Abstract: Rolling mills, especially for sheet metal, and also paper, rubber and similar rolling mills, require accurate control of the gap between the rolls since this determines the uniformity of the gauge of the material rolled by the mill. This invention provides a rolling mill with sensors that cooperate with the circumferential surfaces of the rolls, or rigid parts thereof, to detect relative movement of the rolls in directions that affect the roll gap and the gauge of the material being rolled. Response of the sensors operates a transducer to affect automatic correction of changes in the spacing of the rolls from one another.

Abstract: This disclosure relates to a poker table with two top sections that fold together for convenient storage and with two folding legs attached to each of the sections. The sections are connected together by invisible hinges and there are detachable fastening means on the sections to prevent folding when the table is set up ready for use. Chip-holding recesses in the top surface have fillers that may be used to give the table top a flush surface for use as a dining table. The preferred construction is a plastic molding for each section and a polygonal shape with the recesses and fillers corresponding to the shape of the polygon.
