Abstract: A static mixer for mixing of different media comprises mixing elements arranged within a tube, at which the mixing elements are twisted to divide and divert the media. The mixer is constructed of units each comprising at least one mixing element (1) arranged within a tube part (4). The mixing element is firmly connected to the tube part along its whole length of extension. The mixing elements seen in a cross-section has wing shape with the largest cross-section in the front part (2) of the element seen in the direction of flow of the media, while the rear part (3) seen in the flow direction has a thinner cross-section.

Abstract: An improved system and method for gravimetrically feeding material at a controlled rate. The material to be fed, which can be either a dry solid or a liquid, is maintained in a supply vessel. A probe disposed in the supply vessel detects the level of the material, sending a high level signal to a controller. A scale weighs the material in the supply vessel, sending a weight signal to the controller. The controller then calculates the density of the material in the supply vessel based on the weight and density of the material. The calculated density is used to affect the feed rate to achieve an operator-input set rate. During refill of the supply vessel, the probe detects material at a high level, sending a signal to the controller which, in turn, sends a signal to a refill valve, stopping refill.

Abstract: A method is provided for filtering shredded cellulose-based material, for example to enable the formation of a mixture containing cellulose dispersed in a solvent for cellulose such as amine oxide. The shredding operation creates both fine particles of cellulosic material ("pulp dust") and large particles of cellulosic material, The shredded cellulosic material is passed through a separator to separate the pulp dust from the large particles of cellulosic material and the pulp dust is subsequently recovered in a filtering process.

Abstract: The present invention provides an improved structure for connector terminals for use in computers, directing primarily to terminals for serial and parallel connectors wherein one end of the terminal is a contacting section and the other end is a connecting section with an inserting section interposed therebetween for inserting a plastic base to be joined therein.

Abstract: Apparatus and method for low cost monitoring the level of signal at a test point in a system for susceptibility to electromagnetic fields. A probe, including a detector diode, and a non-metallic, electrically overdamped conductor, which is transparent to the electromagnetic field, is used to monitor the signal level at a test point as an amplitude modulated radio frequency carrier. The carrier is transmitted to a monitor outside of the range of the electromagnetic field using a transmission link, such as an optical waveguide transmitter, that is transparent to the electromagnetic field when the system under test fails. The system under test can then be removed from the electromagnetic field and, for each frequency at which the system failed, a voltage can be injected, using a voltage injection probe, into the system at another point to recreate the detected level of signal at the test point that was coupled into the system from the electromagnetic field.

Abstract: A method is disclosed of forming a premix which is suitable for conversion into a cellulosic dope which can be used to produce cellulosic products. The method involves introducing into a mixing chamber predetermined quantities of shredded cellulosic material and a solution of amine oxide at an elevated temperature and stirring the mixture for a period of time by rotating mixer blades within the mixing chamber at a speed of between 40 and 80 r.p.m..

Abstract: An improved modular currency validator and stacker with a removable currency cassette and a removable currency validator and transport unit is described. The cassette and the validator and transport unit are slidably guided into their operating positions using guides in the chassis, and a currency transport extends from an entry in the validator and transport unit to a prestacking position in the removable cassette. Engagement of a transfer gear in the chassis with gears in the validator and transport unit and the cassette is enhanced by offsetting the gear center lines in a direction perpendicular to the guides, and by enlarging the operating pitch of the gears.

Abstract: A liquid crystal lens assembly that can be used to replace existing color lenses in traffic signals without the need for any special modifications to the traffic signal. The lens assembly utilizes a dichroic liquid crystal mixture that absorbs light when no electric field is applied to the mixture. When an electric field is applied across the liquid crystal mixture by two electrodes, the molecules change their orientation within the mixture and absorb less light, and the signal appears "on". The illumination of the bulb behind the lens assembly is visible to the user. The electric field is energized at the same time that the bulb for the traffic signal is illuminated. A colored transflector positioned in the rearward portion of the lens assembly provides the color for the signal and also acts to reflect light from the front of the lens assembly. Wires for applying the electric field to the electrodes connect directly to the terminal block for the traffic signal.

Abstract: A noninvasive device and methods for measuring the end-tidal carbon monoxide concentration in a patient's breath, particularly newborn and premature infants. The patient's breath is monitored. An average carbon monoxide concentration is determined based on an average of discrete samples in a given time period. The ratio of the end-tidal portion of the breath flow sample is separately determined, preferably based on monitoring the level of carbon dioxide in the gas sample and identifying the carbon dioxide concentration levels corresponding to the end-tidal portion of the breath sample. The sensed carbon monoxide level is converted to the end-tidal carbon monoxide level by subtracting the ambient carbon monoxide level and dividing the remainder by the ratio of end-tidal breath to breath in the breath sample.
