Abstract: An extrusion system, for example for extruding a food product, that includes: an extruder, which propels extrudate through an outlet of the extruder; and a valve. The valve includes: an inlet, which receives extrudate from the extruder outlet; a main conduit, which extends from the inlet to a main outlet; a dumping conduit, which extends from a junction with the main conduit to a dumping outlet; and a flow control member, which is operable to move between: a plurality of flow controlling positions, in which extrudate is directed to the main outlet, with the flow control member providing, for each flow controlling position, a respective amount of impedance to flow along the main conduit; and a flow diverting position, in which extrudate is directed along the dumping conduit to the dumping outlet.

Abstract: A heating device may include a substrate and a heating element disposed on a surface of the substrate. The heating element may include an ohmically resistive coating having a layer thickness of 2 to 300 microns. The ohmically resistive coating may include at least 30% by weight of at least one ductile or malleable metal and a plurality of electrically resistive particles. The ohmically resistive coating may be deposited via the at least one of the cold spray and the solid state deposition performed at a temperature below at least one of a melting temperature and a partially softening temperature of the at least one ductile or malleable metal. The ohmically resistive coating may exhibit less heterogeneity and porosity than a thermally sprayed coating, may have a density of 90% or greater, and may have a porosity of 10% or less.

Abstract: A computer implemented method is disclosed for detecting a mild traumatic brain injury (mTBI) on a subject having recently suffered a head injury. The method includes (1) receiving first electrocardiogram (ECG) data from the subject during a first transition from a first position to a second position; and (2) determining a probability value of mTBI within the subject based at least partially on the first ECG data during the first transition. The first position may be a prone position or a supine position and the second position may be a standing position.

Abstract: A foam-applying nozzle including a generally hollow housing. An eductor disposed in the housing has a generally hollow body with a wall, the hollow of the body forming an eduction chamber. An eductor inlet and an opposing eductor outlet are in fluid communication with the eduction chamber. A plurality of jet inlets extend into the wall of the body, the jet inlets terminating in jet ports that are in fluid communication with the eduction chamber. The jet inlets are configured to receive a predetermined portion of a pressurized fluid, the portion exiting through the jet ports generally toward the eductor outlet, creating a vacuum in the eduction chamber. The vacuum is configured to draw a foam solution into the eductor inlet, the foam solution mixing with the aforementioned portion of pressurized fluid in the eduction chamber to form a foam mixture.

Abstract: An automated system and method for storing document data in a Web based document management system is provided. The method includes specifying a first identifier, scanning a document to produce an image file and resizing the image file to produce a resized image. The resized image has a width that is less than or equal to a maximum width at which a display unit can display the resized image entirely without resizing the resized image further or at which a printer can print the resized image entirely without further resizing the resized image. The method also includes extracting text data from the image file or the resized image file to produce a text file, uploading the text file and image file to a server, indexing the text file and image file in the server, and making the text file and image file accessible via the Internet by a web browser.

Abstract: An iris assembly for a prosthetic eye comprising a button having a frontside surface. An iris member is joined to the button frontside surface and has an iris image disposed thereon. The iris image is provided using digital image capture, storage, enhancement, and printing techniques, and is provided onto a suitable substrate. A cornea piece is made from a clear material, and is joined to the iris member frontside surface. Prior to joining, the iris member is encapsulated with a clear protective film thereover that operates to protect the iris image from unwanted smudging or other type of distortion during the step of joining the cornea piece. The iris assembly yields an accurate reproduction of the iris portion of a patient's natural eye in a manner that is both time efficient and cost effective.

Abstract: The external seal is mounted on a housing about a rotary shaft projecting through an opening in the housing. The seal is a resilient, flexible member having a generally tubular body portion with an annular lip extending radially outwardly from one end of the body portion and a flange extending radially outwardly from the other end of the body portion. The lip extends into a sealing chamber formed by the outside of the housing and a replaceable sealing member which has an inside surface spaced from and parallel to the outside of the housing. The tubular portion of the seal extends through an annulus formed by the shaft and the replaceable member. The outwardly extending flange is used to prevent the clamp holding the seal to the shaft from falling out.

Abstract: In a vane type magnetron oscillator a resonant co-axial transmission line breaks through the wall of the anode block to couple to two adjacent cavities on either side of a vane. Positioned at a point at which a high radio frequency voltage appears in operation approximately an odd multiple of a quarter wavelength (preferably 3.lambda./4) from the end of the transmission line adjacent the cavities is a multipactor discharge arrangement. This latter consists of two co-axial cylinders one connected to the inner conductor and the other to the outer conductor of said transmission line. The transmission line extends beyond the multipactor discharge arrangement to a total length approximately half wavelength or a multiple thereof and is short circuited at its end.

Abstract: This invention relates to a co-axial magnetron in which a separate resonator incorporating a multipactor discharge arrangement is used to tune the operating frequency of the magnetron. The separate resonator is symmetrically coupled via couplers into the main resonator cavity of the magnetron. More than one separate resonant can be provided, in which case they are symmetrically coupled into the main resonant cavity to achieve correct tuning.
