Patent DK-405287-D0 (DK)
Inventor: LUSZCZ STANLEY J
IPC: C04B35/65
Filed: 1987-08-04
Abstract: The disclosure concerns self-supporting ceramic structures, including ceramic composite structures embedding a filler, and methods of making them. The ceramic structures comprise a polycrystlline material made by oxidation of a body of molten parent metal with an oxidant. The polycrystalline material has a first region substrate surmounted by a terminal region stratum which is integral with the first region. The terminal region stratum which is harder and of denser, finer crystalline structure than the first region substrate and is formed in a reaction stage subsequent to the reaction stage in which the first region of polycrystalline material is formed. Growth of the first stage is attained by by attenuating or interrupting the transport of molten parent metal to the first region under conditions which nonetheless leave or maintain therein enough oxidizable molten parent metal to form the polycrystalline material of the terminal region.

Inventor: MOBLEY JOSEPH G
IPC: H04N5/44
Filed: 1986-08-18
Abstract: In an FM television signal angle modulated with luminance and chrominance information, there exists a high degree of correlation between picture elements occurring one line period apart. In an effort to steer the pass band of a tunable bandpass filter to the instantaneous frequency of the incoming television signal, a steering signal is developed which utilizes this high degree of correlation. For NTSC systems, luminance information is delayed by one-line period (63.5 us in the U.S.A.) and combined with suitable delayed chrominance information to form the filter's steering signal. For MAC systems, one-line delayed luminance and two-line delayed chrominance information are alternately applied to the filter as its steering signal. By steering the pass band of the filter to the incoming signal, maximum signal will be captured with minimum noise, enhancing the signal-to-noise ratio of a color television system.

Abstract: When polymerizing 1-butene either alone or together with minor quantities of (below about 10%)of other unsaturated monomers, a Ziegler-Natta- composition may be used as high-yield-catalyst, in which, by means of a combination of a solid tetravalent Ti compound supported on MgCl2, an organic Al compound and possible electron donors, liquid hydrocarbon containing 5 to 12 C atoms has been prepolymerized. With this prepolymerized catalyst composition 1-butene may be polymerized particularly in a gas phase. The catalyst composition obtained and the final 1-butene polymer are highly crystalline and do not adhere to each other, and are thus easy to handle and most fluid. The mechanical properties of the product polymer, such as hardness, elastic modulus, tensile strength, yield point, impact strength, etc., are high, and the optical properties, such as light transmission, are equally good.

Abstract: The apparatus of the present invention relates to a down hole tool capable of extraction of valid samples and making pressure measurements useful in calculating formation permeability. The tool incorporates the features of a straddle packer to allow formation fluid specimens to be taken at large flow rates without depressing the pressure below the formation fluid bubble point. When used in combination with a pressure probe the tool is used to obtain meaningful permeability readings in a larger radius area than previously permitted with known designs. Additionally, the apparatus of the present invention allows flow control during the creation of the pressure pulse which enhances extraction of valid samples and the permeability determination. The apparatus is modularly constructed so that in a single descent of the tool, a pressure profile of the zone of interest can be made, a fluid analysis can be made at each station, multiple uncontaminated fluid samples can be withdrawn at pressures above the bubble point, local vertical and horizontal permeability measurements can be made at each station, a packer module can be set at a location dictated by previous measurements and a large scale pressure build up test can be performed. <MATH>

Date Aug. 10, 1989.A method and apparatus for enabling refrigerants, preferably freons, to be emptied from refrigeration systems or heat pump systems with the aid of piston compressor pumps when repairing or scrapping such systems. The compressor suction line is connected to one chamber of a heat exchanger and a pressure reduction valve is connected in the suction line upstream of the heat exchanger. The pressure line extending from the compressor passes to an oil separator and then to the other chamber of the heat exchanger. The fall in pressure in the reduction valve and heating of the refrigerant in the heat exchanger causes the refrigerant to be in a gaseous state when reaching the compressor, which is a prerequisite for safe operation of the compressor. The pressure increase achieved in the compressor pump and cooling of the refrigerant in the heat exchanger enables the refrigerant to be delivered to a container, preferably in a liquid state.

Date Apr. 4, 1996The invention relates to a heat exchanger wherein the heating vapor is fed onto heat exchange surfaces of membrane material from a vapor distributor, the vapor distributor having parallel conduits for directing vapor over the entire width of the surfaces. According to the invention the vapor distributor is made up of two opposing wall elements which are fastened to each other by means of projections in one element and corresponding recesses in the other element. The upper end of the membrane constituting the heat exchange surface is locked between the projections and recesses that are fastened to each other. Thus, pleats are produced in the membrane as an expansion leeway for the vapor space delimited by the membrane. The heat exchange surfaces may be formed into bags, the ends of which are fastened between the interlinked wall elements in such a manner that the vapor conduits delimited by the elements will direct heating vapor to the inside of the bags and the liquid conduits will direct liquid to be evaporated onto the outer surfaces of the bags.
