Abstract: A machinable 3-D printing build plate that can be assembled from a number of different components into the base for a metallic 3-D printing volume and other 3-D printed parts. The build plate can be assembled into a final structure then machined to the required planar tolerance such that the build quality of the part is maintained throughout the build. Additionally, because the baseline printer support structure and support device are comprised of multiple elements, if one or more goes out of tolerance or requires adjustment to accommodate a new print, it may be easily removed, replaced then machined back to the required tolerances.

Abstract: Systems and methods for wire arc additive manufacturing systems that print in horizontal orientations are described. Horizontal WAAM 3D print systems comprise metal 3D print systems in a horizontal orientation with one or more robots operating concurrently on a work piece using one or more wire feeds and a rotating, horizontal build plate.

Abstract: An acoustic dual-frequency phased array system with common beam angles is disclosed. In one aspect, the system includes a planar array of transducer elements and a multiplexing circuit for selecting between a first state and a second state during either transmit operation, receive operation or both transmit and receive operation. The multiplexer is configured to connect transducer elements to a plurality of connections different between the first state and second state. The system is configured to transmit and receive beams at a first frequency when the multiplexer is in the first state and transmit and receive beams at a second frequency when the multiplexer is in the second state. The angle of the beams from vertical in the first and second state are substantially similar.

Abstract: The subject invention relates to a novel gene referred to herein as DSM-2. This gene was identified in Streptomyces coelicolor A3. The DSM-2 protein is distantly related to PAT and BAR. The subject invention also provides plant-optimized genes encoding DSM-2 proteins. DSM-2 can be used as a transgenic trait to impart tolerance in plants and plant cells to the herbicides glufosinate and bialaphos. One preferred use of the subject genes are as selectable markers. The use of this gene as a selectable marker in a bacterial system can increase efficiency for plant transformations. Use of DSM-2 as the sole selection marker eliminates the need for an additional medicinal antibiotic marker (such as ampicillin resistance) during cloning. Various other uses are also possible according to the subject invention.

Abstract: A sintered polycrystalline diamond material (PCD) of extremely fine grain size is manufactured by sintering under high pressure/high temperature (HP/HT) processing, a diamond powder which is blended with a pre-milled source catalyst metal compound. The PCD material has an average sintered diamond grain structure of less than about 1.0 ?m.

Abstract: Microfluidic delivery systems for dispensing a fluid composition into the air comprising microfluidic die and at least one heating element that is configured to receive an electrical signal comprising a certain on-time and wave form to deliver a fluid composition into the air.

Abstract: There is provided a method and apparatus for tuning an optical discriminator to the carrier frequency of an optical signal to allow superior reception of said signal. The carrier frequency of the signal is dithered during a test phase in order to provide information that allows a subsequent tuning phase to optimise the reception of the optical signal, as measured by a signal quality metric. The tuning phase may comprise adjustment of one or both of the carrier frequency and the optical discriminator.

Abstract: A method of making a cutting tool insert, including positioning and fixing an abrasive tip in a mold, filling the mold with a powder metal mixture, and infiltrating the powder metal mixture around at least a portion of the tip to define a green body. The method further includes compacting the powder metal to define a pressed green body, sintering the pressed green body to yield a sintered body having a metallic portion and a tip portion, and cooling the sintered body to put the tip portion into compression. The tip portion is non-adhesively mechanically attached to the metallic portion.

Abstract: A method for characterizing a three-dimensional spatial distribution of a characteristic of an ultra-hard body includes successively removing portions of the ultra-hard body to successively expose sub-portions, determining a characteristic of each of the exposed sub-portions, and reconstructing a three-dimensional spatial distribution of the characteristic of the ultra-hard body from the determined characteristic of each of the sub-portions.

Abstract: This invention pertains in part to the development of a vaccine for poultry against necrotic enteritis (NE). The vaccine utilizes a protective antigen that is a mutated, full-length, non-toxic Clostridium perfringens (Cp) ?-toxin protein (Mcpa). Utility of this vaccine was demonstrated by reduction of lesion severity in NE challenge trails, for example. Also disclosed herein are novel approaches for producing this vaccine in significant quantities. One exemplified approach involves producing NE vaccine (mutated alpha toxin) in bacterial expression systems, preferably utilizing the Pseudomonas fluorescens system, for commercial use in controlling NE in the poultry industry. The subject vaccines can be administered preferably to chickens in several different ways. A novel, Type VI alpha toxin from chicken isolates of Cp is also disclosed.

There is at least one gap between the press fitting together with the sealing ring and the tube which is closed by pressing at least one portion of the press fitting. The sealing ring has at least one first portion along the majority of its circumference. Each first portion of the sealing ring has an outside diameter SOD1 prior to fitment into the press fitting bead which is larger than the inside bead diameter BID and an inside diameter SID1 prior to the insertion of the tube which is less than the tube outside diameter TOD. Additionally, the sealing ring has at least one pair of diametrically opposing second portions, each second portion of the sealing ring comprising a recess between the two projections.

Abstract: A portable device that produces inconspicuous sounds for event notification is disclosed. One type of inconspicuous sound is a sound that the human body makes in response to an involuntary bodily function. For example, the portable device could produce the sound of a cough to alert the user of an event. Other types of inconspicuous sounds are sounds that are commonly heard in the environment. For example, when in a restaurant the sound of clinking glasses is a common sound.
