Abstract: A two-dimensional layer is deposited onto a substrate in a CVD reactor, in which a process gas is fed into a process chamber. The process gas in the process chamber is brought to the substrate, and the substrate is heated to a process temperature. After a chemical reaction of the process gas, the layer forms on the surface. During or after the heating of the substrate to the process temperature, the process gas with a first mass flow rate is initially fed into the process chamber and then, while the substrate surface is being observed, the mass flow rate of the process gas is increased to a rate at which the layer growth begins, and subsequently the mass flow rate of the process gas is increased by a predetermined value, during which the layer is deposited. The beginning of the layer growth is identified by observing measurements from a pyrometer.

Abstract: A coating is deposited on a substrate in a CVD reactor that includes a process chamber and a gas inlet member with a first gas distribution chamber and a second gas distribution chamber separate from the first gas distribution chamber. To deposit heterostructures, in a first step, an inert or a diluent gas is fed into the first gas distribution chamber and a reactive gas containing the elements of a first coating is fed into the second gas distribution chamber. The reactive gas pyrolytically decomposes in the process chamber to form the first coating on the substrate. In a second step, a diluent gas is fed into the second gas distribution chamber and a reactive gas containing the elements of a second coating is fed into the first gas distribution chamber. The reactive gas or gas mixture decomposes in the process chamber to form the second coating on the substrate.

Abstract: A measurement probe is described that includes a probe body, a stylus that is deflectable relative to the probe body, and a plurality of sensor elements for generating a sensor signal indicative of stylus deflection. An analyser is provided, optionally as part of a trigger unit, to analyse the sensor signals and issues a trigger signal to indicate the stylus has contacted an object. The analyser is arranged to combine a plurality of the sensor signals to generate a resultant deflection signal for comparison to a deflection threshold and is also arranged to detect oscillatory motion of the stylus by analysing at least one of the sensor signals. The analyser only issues a trigger signal when the resultant deflection signal crosses the deflection threshold and no oscillatory motion of the stylus is detected. The measurement probe may be used on a machine tool or other coordinate positioning apparatus.

Abstract: A harvesting unit with a combine, having a user cab. A harvesting apparatus, advanced by the combine, has a frame and a harvesting assembly on the frame configured to process severed crop over a width between spaced sides of the frame. A fluid delivery system discharges pressurized fluid in discrete streams each directed to at least one of: a) facilitate severance of crop by the harvesting assembly; and b) facilitate advancement of severed crop rearwardly in relationship to the frame for further processing. A user can selectively vary at least one of: a) a volume of pressurized fluid; and b) a direction of pressurized fluid in the discrete streams. A control system has at least one actuator accessible and operable from outside of the cab through a user input to cause the at least one of the volume of pressurized fluid discharged, and direction of the pressurized fluid, in the discrete streams to be varied.

Abstract: A sectionalized Bible and method to systematically expose readers to interesting broad divisions of the Bible by a new combination of: a) A reading control system consisting of visually prominent new topical sections superimposed on the traditional Bible text with matching bookmarks together with b) A method of reading a chapter or predetermined length from all such sections together in reading sessions that “loop” back to the beginning of a section on its completion while maintaining reading positions within each section by a prominent matching set of bookmarks. Such reorganized Bible and method providing advantages and motivation to modern short-attention readers wanting to “skip ahead” and “get to the good parts” quickly, or to focus on reading without pastoral explanations, discussions, meetings or travel. Such combination improves readability of any version of Catholic and/or Protestant Bible to grow familiarity, reading habit, and show relevance, connectedness and value of Bible content.

Abstract: Process producing ultra low carbon steel strip or sheet including producing a vacuum-degassed steel melt in a steelmaking step including a ladle treatment containing, by weight, at most 0.008% carbon; at most 0.008% nitrogen; at most 0.20% phosphorus; at most 0.020% sulphur; balance iron and inevitable impurities. Melt target oxygen content at end of ladle treatment of the melt is obtained by measuring the melt actual oxygen content followed by adding a suitable amount of aluminium in a suitable form to the melt to bind oxygen. Melt target oxygen content at the end of the ladle treatment is at most 80 ppm. Casting steel thus produced in a continuous casting process to form slab or strip. The process provides slab, strip or sheet of ultra low carbon steel containing at most 0.002% of acid soluble aluminium and at most 0.003% silicon and total oxygen content at most 100 ppm.

Abstract: A system for cleaning a particulate trap comprises locating the trap in a chamber and forcing cleaning air through the trap. The air and removed particulates is extracted from the trap towards a filter. The expelled air essentially without the removed particulates from the chamber, the removed particulates being essentially trapped in the filter. The trap is locatable about a longitudinal axis such that air is urged in a longitudinal direction through the trap. The trap is supportable on at least one rotatable roller to affect rotation about the axis. A motor and blower draws air from the chamber and an air pressure differential about the filter causes the particulate to be directed through the filter and excess air is pumped out of the blower by the motor operating the blower.
