Filed: 1990-02-23
Granted: 2000-07-18
Abstract: A system for integrating and modularizing wiring within a building is provided herein. A unitized destination terminal integrates a diverse assortment of communication connectivity needs with power distribution. The terminal mounts near a work surface in each one of a multiplicity of work areas within a building. An integrated communication cable bundle transports a variety of different communication circuits away from the work areas towards a common communication distribution area. The integrated communication cable bundle is routed through an integrated raceway, which manages the placement and housing of communication systems as a unit that additionally includes power distribution systems. Cabinets, at the common communication distribution area and at a central connectivity area for the building, terminate communication cabling at a variety of socket connectors. The central connectivity area couples e.g., to PBX, mainframe computer controllers, or other connectivity devices. A variety of jumper cables mate with the socket connectors in a selectable and easily-alterable pattern to couple the connectivity devices, e.g., a PBX, to the unitized destination terminals in the work areas. Extensive modularization and off site connectorization permit such system to be installed quickly and inexpensively without the use of highly-skilled electricians. The extensive connectorization, as opposed to hard-wiring, and integrated management of a wide assortment of communication channels promotes flexibility.

Title: Threaded and non-threaded fastener improvements
Inventor: KRYWITSKY LEO L
IPC: F16B39/02
Filed: 1992-03-17
Granted: 2000-11-21
Abstract: Most mechanical joints, both sealed and not sealed use either threaded fasteners such as conventional nuts, bolts and set screws or non-threaded fasteners such as conventional spring pins. Safety, economy, reliability and environmentability of structures, piping systems, both portable and fixed, their combination, mechanical equipment, power plants, jet liners, ships, etc., rely on the predictable performance of involved fasteners.      Due to the variety of factors, a predictable performance of corresponding commercial fasteners is not always fully attainable.      Such uncontrollable conditions as in-service thermal cycling, vibration, metal flattening, metal fatigue, human error, possible malpractice, tampering with or neglect, occuring during installation, operation or maintenance, make performance prediction difficult and increase associated costs.      This invention comprises a number of value-added improvements of commercial fasteners which may significantly increase the accuracy of prediction in safety, economy, reliability and environmentability of involved systems if proposed improved fasteners are used.      Related, authenticated tests carried out earlier have proved that the claimed herein self-locking and self-tightening features are indeed attainable. Proposed related manufacturing processes and operation plans involving a combination of automated CNC high technology (Lasers) and CNC low technology (mechanical equipment, dies, tools, fixtures, etc.) may result in these high quality products produced at relatively reasonable cost.

Abstract: An improved plastic push in tube fitting includes a plastic body, an elastomer o-ring for sealing, and a plastic collet. The collet and o-ring are disposed in the body such that a tube can be pushed into the body through the collet and o-ring and held against withdrawal from the body by the collet. The collet is formed entirely of plastic and has a plurality of circumferential sections for encircling a tube pushed into the body. Each of the circumferential sections has a radially inwardly facing circumferential tube gripper. The tube gripper is formed by a ramp which faces a tube being pushed into the body so that the collet will encounter the ramp and move the circumferential sections radially apart. The gripper also includes a circumferential surface which faces away from a tube being pushed into the body. The circumferential ramp and the circumferential surface form a gripper edge at their junction and this edge engages and holds a tube pushed into the body through the collet. Preferably the ramp has an angle with respect to a tube pushed into the collet of between 15 and 40 degrees. Also preferably the internal angle between the circumferential ramp and the circumferential surface is between 75 and 120 degrees. The arcuate shape of the gripper edge is the same as the arcuate shape of the exterior of a tube pushed through the collet. The collet preferably is formed of hard plastics, such as poly (ether ether ketone), polyetherimide, polybutylene terephthalate, polyphthalamide and polymers of acetal homopolymer.

Title: Foaming nozzle for sprayer
Inventor: TASAKI TAKAHARU
IPC: B05B11/00
Filed: 1991-10-01
Granted: 2000-04-11
Abstract: Herein disclosed is a foaming nozzle to be mounted in the front of a spray nozzle of a sprayer so that a liquid detergent may be sprayed in a foamed state onto a window glass or the like to clean it. The foaming nozzle has its mouth so shaped that the mixed cluster of the mist and foam from the foaming nozzle may be sprayed in a band, elliptical, rectangular or triangular shape and at a wide angle. At the same time, the positional relation between a spray port and the foaming nozzle is so determined that the mist spin-sprayed at a high swirling speed may be partially mixed with the foam, which is formed by the impingement of the mist upon the inner face of the mouth of the foaming nozzle, and that the mixture may be sprayed at a wide angle. The foaming nozzle is composed of first and second foaming nozzles, of which the first one is mounted in the spray nozzle, as described above, whereas the second one is formed into the shape of a circular cylinder and removably hinged to the first one so that the mist-foam mixed cluster may be sprayed in the sectional shape of a band from the first foaming nozzle with the second foaming nozzle being removed and so that foam may be sprayed in the sectional shape of a circle with the second foaming nozzle being unremoved. In short, the user can selectively spray either the mist-foam mixed cluster having the band section or the foam cluster having the circular section freely, if necessary.
