摘要:
A measurement instrument for measuring the vertical height between two points, the device comprising: first and second rotatable measuring units (4, 6); and a processor (8) for processing data from the first and second measuring units and calculating the vertical height between the two points, wherein the first and second measuring units each comprise a rangefinder (10L, 10R) for measuring the distance from the measurement device to the first and second points respectively and an angle measurement device (16L, 16R) for calculating the angle through which the rangefinder is rotated in order to measure the vertical height.
摘要:
An aqueous chlorine dioxide solution which comprises dissolved chlorine dioxide in a concentration of about 10 to 3000 mg/l, pH in the range of about 1 to 6, and a chlorine scavenging means such as sodium chlorite in a ratio in the range of about 1:4 to 1:15 (w/w) sodium chlorite to chlorine dioxide. The chlorine dioxide solution may be stored for use over a period of several days to several months.
摘要:
A method of adjusting the output of an electrochemical sensor includes the steps of: simulating the presence of an analyte gas electronically; measuring a response of the sensor to the electronic simulation; and adjusting the output of the sensor as a function of the measured response to the electronic simulation. The method of adjusting the output of an electrochemical sensor having a working electrode and a counter electrode preferably includes the steps of: electronically causing a current flow between the working electrode and the counter electrode; measuring a response of the sensor to the current demand; and using the measured response to adjust the sensor output during sampling of an analyte gas.
摘要:
A barrier net (1) across a space defined by the fuselage (2) of an aircraft (3) and a floor (4) of the aircraft comprising a plurality of intersecting net members (5), at least some of the members (5) being: (i) attached to the fuselage(2) by attachment means (6) attached to attachment points (7) on the fuselage (2) of the aircraft (3); and (ii) held forward of the attachment points (7) so that a major portion of the net (1)is in a plane further forward than the attachment points (7).
摘要:
A flow cytometry system (1) for sorting haploid cells, specifically irradiatable sperm cells, with an intermittingly punctuated radiation emitter (56). Embodiments include a beam manipulator (21) and even split radiation beams directed to multiple nozzles (5). Differentiation of sperm characteristics with increased resolution may efficiently allow differentiated sperm cells to be separated higher speeds and even into subpopulations having higher purity.
摘要:
The present invention provides a foam composition comprising an active agent. In particular, the foam composition produces a water resistant, preferably very water resistant, film upon application.
摘要:
A non-toxic corrosion inhibitor and method comprising hydrotalcite or a hydrotalcite-like complexing agent and one or a combination of an organic or inorganic corrosion inhibitive complexing agent, provides improved corrosion protection on metal substrates and utilizes synergistic corrosion inhibitive mechanisms.
摘要:
A neck seal for use in a protective hood includes an inner section including a passage for donning. The inner section is fabricated from an elastomeric material to form a seal around a neck of a user. The neck seal also includes an outer section adhered to the inner section. The outer section is fabricated from a material heat sealable to a hood covering material. In one embodiment, the elastomeric material of the inner section is a latex material. The outer section can, for example, be fabricated from a thermoplastic material. In one embodiment the thermoplastic material is a polyurethane such as a polyester-based polyurethane.
