Abstract: A label dispenser in the form of a hand held labeler is shown that is selectively operable in a number of dispense modes. The dispense modes include an on-demand mode in which labels are automatically printed and dispensed as previously printed labels are removed from the labeler. In a manual mode, the labeler is responsive to the manual actuation of a trigger switch to print and dispense a label. The labeler is also responsive to an on line trigger command received from a host device to print and dispense a label. Further, a strip mode allows strips of labels to be automatically printed on demand or in response to the actuation of the trigger switch. An on-demand sensor is employed to detect the presence or absence of a label dispensed from the labeler in the on-demand modes. Further, the quantity of labels or strips of labels automatically dispensed in the on-demand modes may be limited to a specified quantity.

Granted: 2000-12-05
Abstract: 2129367 9320444 PCTABS00027 A method for modifying a liquid assay reagent to provide prolonged homogeneity thereof, particularly where the liquid assay reagent comprises microparticles for performing a heterogeneous immunoassay, is provided wherein the addition of an inert material to a liquid assay reagent achieves neutral density to thereby prolong the homogeneity thereof for extended periods of time. A method for the automated agitation of assay reagents to maintain the homogeneity thereof with an automated, continuous and random access analytical instrument is also provided. The automated mixing is accomplished by a back and forth motion of a carousel onto which assay reagent containers or packs are mounted with asymmetric pauses which can be completed within a short period of time.

Granted: 2008-10-07
Abstract: In a process for accelerating the setting and hardening of a material which contains a hydraulic binder or which consists of a hydraulic binder there is used a setting accelerating mixture which is free of alkali metals and free of chlorides. Said setting accelerating mixture contains at least one water soluble sulfate of a polyvalent cation and a further constituent which is selected from the group consisting of calciumaluminate, calciumsulfoaluminate, basic aluminum salts, mixtures thereof or mixtures containing at least one of said constituents and a further component. If the water soluble sulfate of the polyva-lent cation is aluminumsulfate then said compound has to contain crystal water in order to provide the water so-lubility of said product. With the setting accelerating mixtures a fast gaining of strength of a corresponding mortar or concrete is achieved and the finally hardened product has better mechanical characteristics than corresponding products prepared without the adding of any set accelerating ad-mixture.

Abstract: A first gas in a laser cavity is ionized by an electrical discharge in the cavity as a step in producing an energy radiation. Debris (particulates) is produced during the formation of the energy radiation. The radiation and the debris move toward an optical element in the cavity. The optical element may be a window or a mirror. The debris tends to deposit everywhere in the cavity, including on the optical element, thereby dirtying the optical element. This inhibits the efficiency in the laser operation. A clean gas is directed into the cavity through a passage at a position displaced from the optical element. The clean gas then passes in the cavity through an orifice further from the optical element than the passage. The flow of the first gas through the orifice creates a venturi effect on the clean gas to insure than the clean gas will move away from the optical element. In this way, the clean gas inhibits the first gas and the debris from moving to the optical element. Baffles in the cavity between the passage and the orifice provide irregularities in the movement of the first gas from the orifice to the optical element, thereby further inhibiting the movement of the debris to the optical element. Baffles in the cavity between the passage and the optical element also inhibit the movement of any gas to the optical element.    An electrically grounded screen in the displaced passage attracts any ions present in the clean gas.

Filed: 1995-10-26
Granted: 2000-03-14
Abstract: A new ultrasonic method for measuring wall thickness and detecting material flaws in natural-gas pipelines (30), risers, and similar structures. The method is inherently suitable for the task, because it relies on the use of the natural gas (G) as the coupling fluid for transmitting the probing ultrasonic signals into and out of the pipe wall. Furthermore, the method facilitates the operation of the inspecting from the inside of the pipe (30). An experimental apparatus is also described. Significantly, it is shown that by the use of a diplexer (18), the same transducer (15) can be used to generate and detect the probing ultrasonic signals. The same configuration is used in commercial ultrasonic inspecting of oil pipelines where oil is the coupling fluid; but until now this method could not be used in natural gas pipelines due to the low specific acoustic impedance of natural gas.

Abstract: A one piece, low-profile hopper tee is provided having a transverse, elongated hollow pipe section with an inlet opening formed at a midpoint in the top side and an integral flange formed around the inlet opening for attaching the hopper tee to an outlet end of a hopper. The distance from the longitudinal axis of the elongated hollow pipe to the top of the flange is not greater that 1.25 times the distance from the longitudinal axis of the elongated pipe section to the top surface of the elongated pipe section. There are wear saddles formed on each side of the flange between the flange and the elongated pipe section. The elongated pipe section has an inner diameter that is uniform at each and gradually increases to the midpoint so as to create a ramp from the inlet opening into the hollow pipe at the area of the wear saddles to facilitate flow of material into the pipe. An alternative embodiment of the low profile hopper tee includes an outflow opening in the bottom side of the elongated pipe and a swing-away door to seal the opening. The low profile swing-away door has a recessed central gasket for sealing the outflow opening when the door is in place.
