Title: Electric and fiber optic cable control and management
Inventor: BEATY ROBERT C
IPC: G02B6/44
Filed: 1990-04-30
Granted: 1993-11-16
Abstract: ABSTRACT      In order to protect electrical and fiber optic cables in a central telephone office terminal equipment frame, the cables are controlled and managed so as to be releasably retained in a service loop within a fiber management panel.  The releasable retention is performed by a stretched extension spring selected, dimensioned and stretched in such a manner with respect to the diameter of the cables that each cable can be gently but firmly retained when pressed into the gap between adjacent coils.  The retention spring permits emergency release of the cable in the event of mishandling of the equipment by service personnel.

Title: Compound toggle link
Inventor: PETERSEN RALPH
IPC: B25B7/02
Filed: 1990-09-11
Granted: 1999-02-16
Abstract: A quick release for a conventional plier-type, toggle-locking hand tool comprises a compound toggle link.   The new link is pivotably mounted between the movable handle and the conventional toggle member.  Four pivot points rather than the usual three form the "power line" of the tool.  Locking the tool involves pushing the two internal pivot points inwardly across the power line.        Release involves opening the handles which moves the internal pivot points back across the power line.  Depending on the dimensions of the  actual hand tool,  the mechanical  advantage of the novel compound link is between 4 to 16.

Title: Process for the safe and environmentally sound production of highly pure alkylene oxide adducts.
Inventor: LEUTERITZ GUNTER M
IPC: C07C41/03
Filed: 1990-09-20
Granted: 1999-05-04
Abstract: An alkylene oxide is reacted in a loop reactor with an organic compound having a reactive hydrogen atom, a gas circulation and a liquid circulation around the reactor being provided and being coupled with one another via an ejector mixing nozzle. To ensure completeness of the reaction and suppression of the formation of by-products such as dioxane, it is essential to reduce the temperature of the entire alkylene oxide gas phase to a temperature below that of the liquid phase, and this is effected by feeding and evaporating liquid alkylene oxide and by cooling of the gas phase on the unit walls.

Abstract: ABSTRACT OF THE DISCLOSURE   A binary digitizing system which is effective when it is desired to reproduce a picture having a half-tone level with use of, for example, a dot printer or the like.  Binary threshold data for comparison with a current picture signal is randomly changed slightly within a predetermined range to such an extent that users cannot recognize change in the level of the binary threshold data, thus preventing the continuation of such regular binary  pattern.  Further, the binary threshold data for comparison with a current input picture signal is changed according to a desired density to obtain a binary picture signal corresponding to the desired density.

Title: Method and apparatus for producing carpeted panels
Inventor: MAINOLFI SYLVIO J
IPC: B29L31/58
Filed: 1991-02-21
Granted: 1994-07-05
Abstract: ABSTRACT OF THE DISCLOSURE Carpeted panels comprising a thermoplastic substrate and a synthetic fiber carpet are produced by bonding the respective parts to one another using a vibration welding apparatus for causing the generation of frictional heat at the interfacebetween the substrate and the carpet. One of the platen of the welding apparatusconfronting the carpet is provided with a pattern of closely spaced pins engaging the carpet and urging the carpet into forced engagement with the substrate. On account of the closely spaced pins and the relatively low amplitude of the reciprocatingmotion, a bond is achieved substantially over the entire interface between the carpet and the substrate.

Inventor: YANO MAKOTO
IPC: H05K3/00
Filed: 1991-09-17
Granted: 1995-01-10
Abstract: A method and a device are provided for generating a multi-pulse laser beam including at least three laser beams, from a single pulse laser beam oscillated from a single laser beam source and a method and an apparatus using the pulse generator for laser beam machining with a two-wavelength multi-pulse laser beam suitable for fine-patterning a multi-layered circuit board formed of metal thin films and resin layers or ceramic bodies.          One pulse laser beam from the laser beam source is separated into linear polarized laser beams in first and second directions by a polarization beam splitter, with the beam in the first direction being outputted as a first pulse beam of the multi-pulse beam.  The beam in the second direction is incident to a combination of an optical fiber or a glass plate and a 1/4 wavelength plate, and is delayed and non-linearly polarized there to become a delayed and non-linearly polarized laser beam.  The laser beam is again incident to the polarization beam splitter, where the delayed non-linearized pulse beam separated in the first direction is outputted as a second pulse beam of the multi-pulse laser beam.  The delayed non-linearized pulse beam separated in the second direction is passed again through the above-described delay and non-linearization loop to generate a third pulse beam.
