Inventor: NAKAGAWA TURUO
IPC: C02F1/24
Filed: 1993-05-10
Abstract: A system for cleaning water in rivers or lakes or for separating oil and water. Stock water to be treated is sucked up by a pressure pump 2 from a portion A to be treated such as a river or lake and is fed to vapor-liquid mixing means 1. This sucked stock liquid is fed with a gas compressed by a compressor 3 so that the compressed gas fed from the compressor is mixed and dissolved by the vapor-liquid mixing means 1 in the stock liquid fed from the pressure pump. After this, the liquid under pressure is reserved in a pressure tank 4 and is fed again to the treated portion A via a feed pipe 6. To the leading end of the feed tube 6, there is attached a pressure valve 5 which is opened at a pressure exceeding a predetermined level, so that it can keep the pressure of the liquid containing the dissolved gas at the predetermined level or more. Thus, a great amount of the very fine bubbles can be produced in the treated liquid of the treated portion d so that flock or oil in the treated portion A can be efficiently lifted by the sticking action of the fine bubbles.      According to this system, the construction can be simplified, and the lifting action by the bubbles can be effected by keeping the pressure of the liquid at a predetermined level or more at all times. Thus, the system can be used anywhere under all circumstances.

Patent CA-2107246-A1 (CA)
Inventor: KENKNIGHT BRUCE H
IPC: A61N1/39
Filed: 1993-09-29
Abstract: A cardioversion/defibrillation electrode comprising an insulative element which supports one or more planar conductive elements. The conductive elements are spaced apart from each other by a "conductor-free" region, which serves as a spring loaded hinge about which the electrode may preferentially bend. The electrode is thereby spring loaded to adopt a substantially planar orientation in a relaxed state but is capable of bending to a non planar orientation wherein the electrode is folded about the hinge to facilitate intrathoracic introduction. After introduction, the spring loaded hinge causes the electrode to adopt its relaxed substantially planar orientation for attachment on or near the heart surface. Due to the preferential bending in the "conductor-free" region, the electrode conductive elements are not permanently or substantially deform during implantation. <IMAGE>   <IMAGE>

Title: Degradable cellulose polymers
Inventor: LIPINSKY EDWARD S
IPC: C08L1/00
Filed: 1992-05-20
Abstract: The present invention is directed to a thermoplastic cellulose ester polymer composition having improved degradation properties upon exposure to moisture. The composition includes a cellulose ester and a degradation promoter. The degradation promoter, after formation of the polymer composition into an end-product and in the presence of moisture, is water soluble and leachable from the polymer end-product or in the presence of moisture, hydrolyzes to form water soluble by-products which are leachable from the polymer end-product. The degradation promoter also acts as a catalyst to enhance the hydrolysis of the cellulose acetate, resulting in a mixture of cellulose and acetic acid. The cellulose can then depolymerize into saccharides that are more biodegradable. The degradation promoter can also act as a plasticizer for the cellulose ester polymer or can be used in combination with other known plasticizers.

IPC: A61K33/40
Filed: 1994-01-04
Abstract: My theory of cancer is cells that have suffered a genetic throw-back to the original life on earth.     The primitive life used carbon-dioxide as we use oxygen and emitted oxygen which was lethal to that type of life. They are cells that have suffered lack of oxygen and emit CO2 which becomes plentiful within the tumor where cancer usually start. It is possible that the tumor wall contributes to the lack of oxygen and may not allow CO2 from escaping.    The cancer cure that I have invented and proved its effectiveness is a suitable mixture of two liquids that will be refereed to as the "Solution", and will be described in detail later in the Specification. It has been 100% effective 100% on skin cancers and breast cancers that are close to the outside of the breast. The use of the Solution on deep internal cancers could work well with the help of the medical profession.          The story of the years it took my invention to manifest is too long to present here.         My first experience was to cure squamous cell class one by my bottom left lip. After having proof that it worked a lady with breast cancer asked me for help. I gave her some of my Solution. She went for final test eight days later, and was found clear of cancer. A month later a registered nurse with melanoma cancer left from an operation was due for chemotherapy. She was very apprehensive of this process and asked her friend to get some Solution from me. She started to use it on a Monday evening. After using the Solution for less then four days she went for tests on Friday afternoon. She had used the Solution for less then four days. There was no cancer. One year later another lady  with breast  cancer came to me for help. I gave her some Solution and one week later the cancer was gone. Other people have had  success in curing cancer on themselves and others. They are very thankful.

Title: Out-of-band loopback control scheme
Inventor: TURUDIC ANDY
IPC: H04B17/40
Filed: 1994-08-31
Abstract: A communications method and a network for carrying out the method are provided. The network includes a loopback command system and a first link station connected to a communications link. The link traverses several loopback-capable devices as it extends from the first link station to a second link station remote from the first link station. The loopback command system controls the loopback-capable devices to cause them to loopback. In order to command a loopback of a particular loopback-capable device, the first link station generates an initial loopback value and forwards the same over the link to a downstream loopback-capable device located along the link.      Each loopback-capable device receives a loopback value from an upstream device, and compares if the received value is equal to a predetermined value. If the loopback value is equal to the predetermined value, the device is placed into a loopback state. Otherwise, the loopback value is modified by the device, and the modified loopback value is forwarded to the next downstream device located along the link. The loopback value may be represented by a digital bit word, or by the position of a particular bit within a bit stream of the link.
