Title: Amplification of target nucleic acids using gap filling ligase chain reaction
Inventor: BIRKENMEYER LARRY G
IPC: C12Q1/68
Filed: 1992-06-26
Abstract: An improved "gap filling" embodiment of the Ligase Chain Reaction (LCR) is described. Gap filling LCR is LCR  wherein at least one of the probes is recessed so that a gap is formed between the adjacent probes when they are hybridized to target.   The gap is filled using polymerase and deoxyribonucleotide triphosphates before ligation of the probes together. There are single and double gap versions, depending on whether one or two probes are recessed and require filling before ligation. The improve-ment resides in selecting and using target sequences such that only a single type, or two types, of deoxyribonucleotide triphos-phate(s) are required to fill double gaps each being 1-10 bases in length, preferably 1-3 bases. Probes having specific sequences are claimed for a number of pathogens.

IPC: C12Q1/68
Filed: 1992-08-04
Abstract: A rapid and efficient method of DNA isolation, storage, and cleavage that provides DNA suitable for amplification by a sequence-specific method is provided. The method for isolating biologically active DNA from a biological sample having DNA-containing structures includes: (1) contacting a biological sample containing DNA-containing structures with a lysis and storage buffer comprising a non-amphipathic chaotropic salt sufficient to lyse DNA-containing structures in the sample and a chelating agent to preserve the DNA from degradation to form a mixture of the biological sample and the lysis and storage buffer; (2) incubating the mixture formed in step (1) with a metal-containing chemical nuclease that cleaves the DNA to DNA fragments; and (3) purifying the DNA  fragments. The DNA isolated can be catenated closed circular DNA, such as kinetoplast DNA of Trypanosoma cruzi. The purified DNA  fragments can be used for amplification in a sequence-based DNA  amplification system employing primers that hybridize to the DNA in order to determine the presence of a specific DNA sequence in the fragements. The combination of the isolation and amplification methods can be useful for the detection of parasitic, bacterial, and viral diseases by identification of DNA sequences associated with the organisms causing them.

Title: Tooth assembly with leaf spring retainer
Inventor: CORNELIUS ERWIN D
IPC: E02F9/28
Filed: 1994-03-18
Abstract: Abstract of the Disclosure Tooth Assembly With Leaf Spring Retainer Tooth assemblies having a tooth attached to an adapter by a retaining mechanism is normally utilized in order to readily replace the tooth which is a high wear element.  It is advantageous to have a retaining mechanism that is both simple, easy to install and remove and provides a high holding force to the pin to offset any tendency of the pin coming out during use.  In the subject arrangement, a substantially flat leaf spring retainer is provided and is located in a retainer opening transverse to a pin.  Upon installing the pin, the leaf spring is forced to flex.  The force needed to flex the leaf spring is likewise the effective force holding the pin in its assembled position.  A central groove is defined in the pin and is of a sufficient size to receive the portion of the leaf spring in contact therewith once the pin is in its installed position. Once the leaf spring drops into the central groove, the degree of deflection of the leaf spring is reduced resulting in the life of the leaf spring being increased.  By having the retainer opening transverse to the pin opening, the strength of the nose portion is maintained.  Likewise, the leaf spring can be made from a substantially flat member.

Title: Method and apparatus for separating solids from gas in high pressure solids-gas stream utilizing a packed bed of the solids
Inventor: BASAK ARUN K
IPC: F23C10/24
Filed: 1994-04-18
Abstract: The invention relates to the separation of a high temperature (e.g. 300-1200 DEG C) and high pressure (e.g. 2-20 bar) solids-gas stream from a pressurized fluidized bed reactor into solids and gas while reducing the pressure of both the gas and solids takes place in a vertical de-entrainment vessel (41) having a packed bed (48) of solids within it. The possibility of fluidization of the solids is minimized by causing the velocity of the gas component of the solids-gas stream to be reduced during, or just prior to, introduction of the gas into the packed bed (48) of solids, e.g. by providing an expanding conical end (451, 452, 453) in the inlet (42) for the solids-gas stream into the vessel (41). A gas permeable solids impermeable element (46) may also or alternatively be connected to the inlet (42) and extend toward (optionally all the way to) the side wall of the vessel (41), to substantially prevent fluidization. The fluidization-preventing element (46) may be a perforated plate, ceramic filter, or wire mesh screen, and may have gradually increasing gas permeability from the inlet (42) to the vessel side wall. A number of different inlet flows to the vessel may be provided, and at least one separated gas and solids outlets (441, 442; 43) leads from the vessel (41) to a low (e.g. atmospheric) pressure area. <IMAGE>

Inventor: EICK STEPHEN G
IPC: G06F17/30
Filed: 1994-07-11
Abstract: Abstract A technique for displaying the results of a query on a database. The technique associates a subquery of the query with a space in a display and represents the results of the subquery by means of a symbol whose appearance varies with a characteristic of the results of the subquery. In a preferred embodiment, the technique is used with queries on a data base of statistical articles. The display is a grid with each field of the grid representing a journal-year pair. A symbol appears in the field if a search of the data base results in a minimum number of hits in the year and journal represented by the pair. The appearance of the symbol varies with properties such as the number of hits and the number of pages in the hits. Bar graphs along the sides of the grid indicate total numbers of hits per journal and year. The symbol for a given journal-year pair changes its color when the pointer is movedover it, and if a mouse button is depressed when the pointer is over the symbol, the data base references for the hits corresponding to the journal-year pair are displayed in an article view window. Sliders control the number of hits required for the display of a symbol and the size of the symbols. The implementation employs memory mapping and caching techniques to achieve rapid generation of a display from the results of a search.
