Abstract: Cellular phones are becoming more common and popular amongst all sectors of the population for business and private conversations, including many children, with about a Billion users worldwide, and about 300,000 new joiners each day. There is much concern and there is already some accumulating evidence that the Microwave emission transmitted by the cellular antenna that is held close to user's head may have deleterious effects on the user, such as for example brain or eye cancer, and possibly even more so for children. One of the most common ways to try to avoid these problems has been the usage of personal earphones with microphone, but on 4/4/2000 it was published worldwide that a research conducted by the "Which?" consumer Magazine in Britain found that in fact the earphone and its cable can act as an Antenna and also expose the user to the microwave radiation. The present invention solves the above problem in using earphones with cellular phones by a reverse and more sophisticated solution than short range wireless earphones, and also solves the problem that many people don't like using headsets at all.

Title: Manufacture of a filtering screen
Inventor: AULD MORTON BARROWMORE
IPC: B01D29/01
Filed: 2002-11-12
Abstract: A method of manufacturing a filtering screen in which a frame of plastics coated metal or reinforced plastics material is located in a jig and at leapt one sheet of wire cloth is placed over the frame and its edges are gripped by pneumatically operated clamps carried by the jig. The clamps ace pneumatically driven outwardly of the frame to tension the cloth in orthogonal directions. The tensioned cloth is pressed against the frame and heated in order to bond the cloth to the frame. The heated material is allowed to cool, and after completion of the bonding step the clamps are released, allowing the frame to be revved from the jig. Where necessary the cloth is trimmed back to the edges of the frame. Two or more layers of wire cloth are bonded to the frame, one above the other, and typically the cloth in contact with the frame is of coarser mesh then the cloth or cloths above it. Apparatus is described comprising a jig adapted to receive and locate the frame, pneumatically operated clamps carried by the jig are adapted in use to grip the edges of a layer of wire cloth placed over the frame and pneumatically driven tensioning means, on the jig, drives the clamps outwardly from the frame to tension the cloth in orthogonal directions. A heated platen is employed to press the cloth against the frame in order to heat and locally melt the plastics material and cause the wires of the cloth to become embedded in ridges in the upper surface of the frame. Drive means effects relative movement between platen and jig to bring the platen into contact with the wirecloth and after heating and bonding has occurred to retract the platen and/or jig so as to remove the source of heat to allow the frame and cloth to cool, to complete the bonding of the cloth to the frame. A separate set of pneumatically operated clamps is provided for gripping all four edges of each wire cloth layer to allow each layer to be individually tensioned. Typically the jig is adapted to receive two frames side by side and the wirecloths are large enough to cover both frames, and after bonding the covered frames are separated by cutting the wirecloth spanning the junction between the two frames.
