20120061452 | APPARATUS AND METHOD FOR ENSURING CONCENTRIC WELD DEPOSITION OF MATERIAL ON A PIPE INTERIOR - A welding jig for ensuring concentricity of an interior surface of a pipe with a circular outer periphery of a bolting flange thereon, comprising (i) a frame member; (ii) two spaced-apart rollers positioned at one end of said frame member, each adapted to remain in contacting engagement during welding with said circular outer periphery of said bolting flange; and (iii) a chill block, having a convexly-curved outer surface of a curvature corresponding to a desired inner diameter of said pipe, adapted to be positioned proximate said interior surface of said pipe. The rollers permit translational movement of the chill block about a center point of said pipe flange when the welding jig is placed on the pipe flange, to permit uniform diametrical deposition of weld material on said inner diameter of said pipe flange. A method of making a pipe is further disclosed and claimed. | 03-15-2012 |

20090218656 | METHODS OF MAKING SEMICONDUCTOR STRUCTURES INCLUDING VERTICAL DIODE STRUCTURES - Semiconductor structures and methods of making a vertical diode structure are provided. The vertical diode structure may have associated therewith a diode opening extending through an insulation layer and contacting an active region on a silicon wafer. A titanium silicide layer may be formed over the interior surface of the diode opening and contacting the active region. The diode opening may initially be filled with an amorphous silicon plug that is doped during deposition and subsequently recrystallized to form large grain polysilicon. The silicon plug has a top portion that may be heavily doped with a first type dopant and a bottom portion that may be lightly doped with a second type dopant. The top portion may be bounded by the bottom portion so as not to contact the titanium silicide layer. In one embodiment of the vertical diode structure, a programmable resistor contacts the top portion of the silicon plug and a metal line contacts the programmable resistor. | 09-03-2009 |
20140008806 | STAIR STEP FORMATION USING AT LEAST TWO MASKS - Apparatuses and methods for stair step formation using at least two masks, such as in a memory device, are provided. One example method can include forming a first mask over a conductive material to define a first exposed area, and forming a second mask over a portion of the first exposed area to define a second exposed area, the second exposed area is less than the first exposed area. Conductive material is removed from the second exposed area. An initial first dimension of the second mask is less than a first dimension of the first exposed area and an initial second dimension of the second mask is at least a second dimension of the first exposed area plus a distance equal to a difference between the initial first dimension of the second mask and a final first dimension of the second mask after a stair step structure is formed. | 01-09-2014 |

20140030250 | BIOCHAR PRODUCTS AND METHOD OF MANUFACTURE THEREOF - A method for producing biochar particles or pellets which use sulphur and other additives. The method includes producing a mixture with biochar and additives selected from sulphur, lignin, and gluten. The mixture is mixed with water and passed through an extruder to produce an extrudate. The extrudate is then cut into pellets. The pellets are then tumbled/spun with each other and heated to result in mostly spheroidal pellets whose mechanical characteristics allow them to be used with well-known agricultural equipment. The biochar can be produced with sulphur incorporated as an outer coating. To produce this sulphur coated biochar, the method includes feeding a biomass feedstock to a pyrolysis reactor, pyrolyzing the feedstock into biochar particles, size-sorting the biochar particles, and coating the biochar particles with the sulphur coating material. | 01-30-2014 |

20120214616 | Adjustable lenght golf tee - An adjustable length golf tee designed for use with a complementary driving range practice mat includes a base member, an intermediary member and an upper member that are telescopingly joined together in an interlocking relationship to form a unitary, inseparable device. Each of the base, intermediary and upper members is hollowed out along the majority of its length. As a result, the tee is designed to collapse or otherwise temporarily deform upon being struck with a golf club, thereby rendering the tee highly durable in nature. In use, the intermediary member is capable of displacement relative to the base member and, in addition, the upper member is capable of displacement relative to the intermediary member to provide the tee with an overall length that can be adjusted between 1.75 inches and 3.40 inches. In this manner, the tee can accommodate a wide range of golf club head sizes. | 08-23-2012 |

20080204981 | ENCLOSURE FOR ELECTRONIC DEVICE - An enclosure for an electronic device includes a base having an outwardly extending peripheral wall which forms a compartment for receiving the electronic device. A caseplate is mounted to the peripheral wall for enclosing the electronic device. The caseplate has an access opening extending completely through the caseplate and located at a switch on the electronic device. The access opening is covered by a thin membrane which protects the electronic device and yet permits actuation of the switch. The caseplate can be decorated by art work on by another layer of material or can be clear and cover the device and an optional art work insert. | 08-28-2008 |

20140084151 | Matrix Assisted Laser Desorption Ionisation Mass Spectrometry Imaging (MALDI-MSI) - A method of preparing a sample for matrix assisted laser desorption ionisation mass spectrometry imaging analysis by a two-step process. Firstly, a MALDI matrix is dusted on to the sample followed by a spray of a suitable solvent onto the dusted sample. The present method has been successfully applied to the detection and mapping of several analyte classes in latent fingermarks. Using the present two-step method, fingermark enhancement, recovery and analysis from different substrate surfaces is now possible enabling visual and chemical information to be obtained simultaneously via remote testing. | 03-27-2014 |
20140309121 | Categorisation Of Biological Deposits Using Matrix Assisted Laser Desorption Ionisation Mass Spectrometry - A method of categorising a human according to pre-determined categories using Matrix Assisted Laser Desorption Ionisation Mass Spectrometry (MALDI-MS) is disclosed. A method is provided to discriminate humans based on gender, for example, by comparing MALDI-MS sample spectral data in the m/z range 2,000 to 30,000 and comparing these sample spectral data with reference spectral data obtained from pre-categorised humans. | 10-16-2014 |
