Abstract: Methods and systems are provided that can automatically facilitate busy line validation (BLV) and emergency interrupt (EI) services with the aid of various sensors and systems that can automatically determine the status of a given phone-line, and further provide a menu of services to a calling party. A calling party that encounters a busy signal during an attempt to call a called party can validate the status of the called line without the intervention of a human operator. If the called line is currently used for a voice conversation, as opposed to a modem or facsimile call, then the calling party can optionally interrupt the ongoing conversation with the permission of the called party.

Abstract: Method of cooling oil immersed transformer or an electrical machine by heat transfer to a liquefied gas, e.g. Freon. A first heat exchanger transfers heat from oil to liquefied gas, which circulates in a closed heat pump circuit with an evaporating cycle. Finally heat is removed by airflow. This done by either using external or remotely cooler unit containing heat exchanger in communication with conventional refrigeration unit on trailer or any fixed or movable applicable method to locate near Transformer, or by directly locating the heat exchanger and/or pre-engineered evaporating coil within the transformer housing connected to outside refrigeration unit. My new Transformer Oil cooler unit can be applied to existing transformers or can be adopted in new design and manufacturing of electrical Transformers, which can have better temperature control, and better cooling for the hot spot area in Transformers. This is a practical and cost effective system to cool electrical Transformers particularly under extreme conditions in which it will boost the transformers output and enhanced its efficiency. My system has not been previously available.      My invention is liquid (Oil) -to-Gas cooling method and not to be confused with current Liquid-to-liquid or any Gas-to-Gas cooling practice.

Abstract: An improved, polymeric surgical membrane, which can be used in a variety of surgical procedures, such as sutured and sutureless duraplasty procedures. For sutureless applications, a textured, discontinuous, outer polymer layer is provided which encourages rapid incorporation and anchoring into surrounding tissue. In cooperation with the discontinuous first layer, a second elastomeric layer provides elasticity and resilience. A third barrier layer is provided to essentially eliminate adhesions and irritation to surrounding tissue. In those applications requiring anchoring sutures, the second elastomeric layer "self seals" against the sutures, essentially eliminating the leakage of blood, cerebrospinal fluid, or other fluids. In addition, the composite structure of the present invention has a high degree of suture retention strength is polymeric with a high degree of biocompatibility, is thin and very flexible.

Abstract: A stabilizing collar for a concrete saw blade provides a rigid blade structure for smoother cutting operations, particularly in partially cured concrete. A pair of the present collars (10a, 10b) are secured to the blade shaft on each side of the blade, clamping the blade securely therebetween. Each collar has a slightly recessed central area and a raised toroidal rim therearound. Clamping the blade and collar assembly tightly on the shaft, compresses the recessed areas and clamps the rim portions of the collars tightly against the blade at some distance outward from the shaft, thereby providing a rigid assembly and essentially eliminating lateral vibration and flexing of the blade. This enables an otherwise conventional concrete saw to be used for cutting "green" concrete, i. e. relatively soft concrete which has only partially cured.

IPC: C08G65/48
Filed: 2003-09-25
Granted: 2011-11-22
Abstract: A novel class of proton exchange membrane materials, sulfonated poly(phthalazinones), were prepared by modification of poly(phthalazinone).  Sulfonation reactions were conducted at room temperature using mixtures of 95-98%  concentrated sulfuric acid and 27-33% fuming sulfuric acid with different acid ratios in order to get SPPEK with degree of sulfonation (DS) in the range of 0.6 to 1Ø The presence of sulfonic acid groups was confirmed by FT-IR analysis, and the DS  and structures were characterized by NMR. The introduction of sulfonic groups into the polymer chains led to an increase in the glass transition temperature and a decrease in the decomposition temperature. Membrane films were cast from solution in N,N--dimethylformamide or N,N-dimethylacetamide. Water uptakes and swelling ratios of the membrane films increased with DS and sulfonated polymers with DS > 1.2 were water soluble at 80°C. Proton conductivity increased with DS and temperature up to 95°C, reaching 10 -2S/cm.

Abstract: There is provided dual use body armor that can be alternately used either as a hand held shield which can be concealed in a standard bag (such as an attache case) or worn as an armor vest, and which can be quickly converted from one use to the other. For this reason the shield would normally be of an approximately rectangular shape. The exact shape may be varied in order to fit in different types of carry bag, or to better conform (for the purpose of comfort or protection) to the shape of the body when unstowed or deployed and worn as a vest. When used as a vest, the invention is preferably comprised of two or more armor panels that unfold or deploy to protect an area of the front and back, and preferably also the side and lower abdomen, of the torso. The front armor panel, back armor panel, side armor panels, and lower abdomen armor panel, are all located on the body by means of a support system. When stowed, the side and lower abdomen armor panels are shaped to fit closely together as in a jigsaw puzzle as the middle layer of a three layer structure. The armor is designed to be unstowed and put on as a vest with no need for fastening or adjustment.
