Disclosed is a method and apparatus for winding glass optical waveguide filaments during drawing thereof. When a spool is full, the apparatus automatically changes spools, attaches the filament being drawn to a spool moved into the winding station, and severs the filament from the full spool.

The invention concerns an apparatus for processing and forming meat for cooking on a vertical rotisserie. The apparatus is utilized in conjunction with a standard meat grinding/mixing system. A portion of the apparatus attaches directly to a standard ground beef mixer such that the rotating motion of the mixer worm is utilized to force meat into a conical mold. Manipulation of a vent allows air to...

A radiation sensor provides on-line measurement of web MD/CD fiber orientation ratio, formation indexes of multiple spatial frequencies, and optical density as it relates to basis weight. A light source illuminates one side of a substrate to be measured. The radiation passing through the substrate is detected by a pair of detectors having fields of view along narrow strips which are perpendicular ...

Apparatus for continuous preparation of rapidly cooled metal particles from a molten source metal by quenching into a quench liquid, wherein a cylindrical quench chamber rotates about its axis to hold the quench liquid against the inner wall thereof under centrifugal force, and a spinner disk within the quench chamber rotates about the same axis to spin off molten metal droplets into the quench li...

A method of forming an optical shield for a laser catheter is disclosed in which a rod of light transmissive material is optically polished and inserted into a tube of similar material and fused and the distal end of the rod is cut and the assembly is optically polished at the distal end.

An improved multiple port memory system has a priority network for selecting between multiple units seeking access thereto. The priority network responds to requests for access and provides encoded port identifying signals indicative of the port to have access. Decode circuitry decodes the encoded port identifying signals and provides unique port enabling signals for the selected port. Decode erro...

PURPOSE:To enable a raw tire to be fed into a vulcanizer without needing any powe means, by a method wherein when placing a raw tire, a support member tilting means is operated to sequentially level movable support members for the raw tire and support them, and when the raw tire is not placed, all of the support members are raised upright by the tilting means. CONSTITUTION:Weights 23, 24 fall in g...
