Title: Listening control channel in a cellular mobile radiotelephone system
Inventor: KALLIN HARALD
IPC: H04W16/32
Filed: 1992-12-08
Granted: 2002-08-13
Abstract: A cellular mobile radiotelephone system listens for call accesses on a control channel of an umbrella cell and on a control channel of a microcell located within said umbrella cell and responds to the call access only on the control channel of the umbrella cell. More particularly, the microcells within a particular umbrella cell are provided with listen-only control channel at the same frequency as the uplink control channel of the umbrella cell. An umbrella cell and one or several of its microcells may therefore each receive the same call accesses. During call access, the umbrella cell and each of the microcells determines the strength of the received signal and forwards this information to the system. The system selects the most appropriate cell out of the umbrella cell and the microcells to handle the call and causes the umbrella cell to respond to the call access on its downlink control channel. Among the umbrella cell and its microcells, there are therefore a plurality of uplink control channels, one for each defined cell, and a single downlink control channel, namely that of the umbrella cell. Cell planning remains unchanged as does a directed retry mechanism. Because there is only a single downlink control channel within the coverage area of an umbrella cell, excessive rescanning is avoided. Furthermore, a call is established at the outset in the most appropriate cell, using resources more efficiently and avoiding congestion in the umbrella cell.

Patent CA-2142943-C (CA)
Inventor: CHANG EDWARD
IPC: B23K1/20
Filed: 1995-02-20
Granted: 1999-12-21
Abstract: A method of depositing a solid substance on the surface of the substrate in which the solid substance is dissolved in a solvent to create a first solution. The solid substance is less finely divided prior to dissolution than when deposited on the substrate and the deposition density of the solid substance on the substrate is regulated at least in part by solid substance concentration. The solid substance is insoluble in a liquified gas and the first solution is soluble in the liquified gas. The solvent also is capable of depressing the freezing point of the liquified gas upon expansion of the liquified gas. The first solution is dissolved in the liquified gas to create a second solution having a sufficient concentration of the solvent relative to the liquified gas that solidification of the liquified gas is substantially prevented upon the expansion thereof. Preferably, this concentration of solvent is a minimum to prevent overuse of environmentally hazardous solvents. The solution is sprayed against the substrate so that a portion of the liquified gas flashes into a vapor and the second solution containing a remaining portion of the liquified gas contacts and thereby coats the surface substrate. The remaining portion of the liquified gas is evaporated along with the solvent, so that the solid substance remains as a deposit on the substrate. The method has particular application to making very fine depositions such as are required in the electronics industry to coat contacts of printed circuit boards with flux prior to soldering.

Abstract: Method and apparatus for manufacturing an elongate composite insulator with a satisfactory dimensional accuracy.  A core rod composed of a fiber-reinforced plastics is arranged within a mold cavity, and an unvulcanized polymeric material is injected into the cavity to integrally mold a sheath which covers the core rod over substantially the entire length thereof and a plurality of sheds which are spaced from each other in the axial direction of the core rod.  The polymeric material is injected into the cavity from a gate, with an injection pressure which acts in a first radial direction perpendicular to the center axis on a mold parting plane.  The core rod during injection of the polymeric material is supported from a second radial direction which is perpendicular to the center axis of the core rod and the first radial direction.  The deflec-tion of the core rod during the injection of the polymeric material is thereby minimized to realize a satisfactory dimensional accuracy of the product.

Granted: 2003-10-28
Abstract: A sifting screen is described comprising a rigid frame, a first woven cloth of hard wearing metal wire, stretched there-across and secured thereto, and a second woven cloth having a coarser mesh than the first cloth and being woven from an elongate material of greater cross-section than the first, also stretched across the frame, and secured thereto, below the first cloth, to support the later against sagging.      In accordance with the invention, at least the wearing surface of the material from which the lower cloth is woven is selected to be significantly less hard wearing than that from which the upper cloth is woven, so that wear due to rubbing and vibration during use, occurs to a greater extent in the lower cloth than in the upper cloth. In one example the upper cloth is woven from stainless steel wire and the lower from phosphor bronze wire. In another example the lower cloth is of wire having a coating of an epoxy based material, or Teflon.TM., or Molybdenum Disulphide. In another example the lower cloth is formed from a plastics material or Kevlar .TM. or carbon fibre. The frame may be formed from glass reinforced gas blown polypropylene reinforced by elongate metal reinforcing elements or rods.
