Abstract: I feel there is a need for submarines to communicate effectively with other submarines ships and airplanes. The same invention can also be used for trapped miners to communicate with their rescuers. If for a moment we oversimplify it, the invention is basically a radio transmitting and receiving antenna system that works under water as well as above it and attaches to standard radio transmitting and receiving equipment. Its purpose is primarily that submarines can communicate with other submarines, even robot submarines, ships, as well as aircraft flying overhead or even land based stations. Whether the submarine is submerged or surfaced should make no difference in transmission or reception of radio signals except for a slight difference in the tuning of the transmitting system. The system also works underground up to a point depending on the distance and radio frequency used. This is basically in a nutshell what it's all about. Unlike other systems in use at present, which work on sound which is plagued by echoes, or the electrical conductivity of water that limits its use to water only, or in some cases in one way transmission only, my system has no such obstacles and even can be used for TV transmission.

Title: Caged compound cleaving process
Inventor: GAWAD YAHIA A
IPC: G01N33/531
Filed: 2002-07-15
Granted: 2011-09-20
Abstract: Caged compounds, i.e. synthetic chemical compounds whose chemical or biochemical activity is normally controlled by photolysis to release an active moiety to participate in a chemical or biochemical reaction, are subjected to electrical current instead of light to release the active moiety. The process is especially useful in chemiluminescent biochemical assays, where it is required to measure the light output in order to quantify the analyte under measurement, since avoids confusion between input energy to trigger the reaction, and light output for measurement purposes.

Abstract: La présente invention a trait à un procédé permettant le contrôle rapide et précis de l'écoulement de métal en fusion vers un appareil de coulée par pompage, freinage ou réglage. Le procédé utilise le principe de circulation de courant de Faraday/Ampère dans un champ magnétique unidirectionnel. Des aimants permanents comprenant du néodyme ou autres matériaux analogues de terres rares à haute énergie assurent un magnétisme étendu. Ces aimants nouveaux, généralement sous forme de cubes, sont disposés dans diverses configurations de puissance entraînant un champ magnétique B unidirectionnel intense à travers un entrefer amagnétique (44) d'une largeur plusieurs fois supérieure à ce qui serait économiquement viable autrement. Cet entrefer (44) loge un conduit (43) pour la mise sous pression et la circulation d'un flux de métal en fusion (M). Pour la production de plusieurs pièces en fonte identiques, un flux de métal en fusion (M) contrôlé, intermittent et prédéterminé est alimenté à une série de moules individuels identiques. L'invention élimine la nécessité d'opérer des vannes métallurgiques ou des mécanismes d'inclinaison coûteux pour des fours métallurgiques. Des fours existants trop bas pour permettre un déversement par gravité peuvent être rendus utilisables par certains modes de réalisation de la présente invention.
