Abstract: The invention relates to methods, uses, systems, arrays, engineered nucleotide sequences and vectors for inhibiting bacterial population growth or for altering the relative ratio of sub-populations of first and second bacteria in a mixed population of bacteria. The invention is particularly useful, for example, for treatment of microbes such as for environmental, medical, food and beverage use. The invention relates inter alia to methods of controlling microbiologically influenced corrosion (MIC) or biofouling of a substrate or fluid in an industrial or domestic system.

Abstract: Disclosed example respirators comprise: a filter configured to filter the air; a blower fan configured to provide continuous air flow at variable speeds; an air duct configured to direct air from the blower fan to an exhaust location, the blower fan configured to blow air through the air duct; and a blower controller configured to: control the blower fan to automatically adjust an airflow speed of the blower fan to a plurality of airflow speeds over a plurality of different time periods, the plurality of airflow speeds being within an airflow speed range.

Abstract: Provided is a powered air blower unit for delivering air flow to a user with constant air flow or varying speeds of air flow. The air blower unit may also include a filter for purifying the air.

Abstract: Provided is a light attached to a helmet where the light does not move when a face shield of the helmet is rotated up or down.

Abstract: The invention relates to a spinning nozzle (10) for the extrusion of a hollow fiber from one or more spinning masses and an apparatus comprising a spinning nozzle (10) as well as method for extruding a hollow fiber by means of a spinning nozzle (10), wherein the spinning nozzle (10) has an inlet port (12, 13, 14) for each spinning mass to be extruded for introducing the spinning mass into the spinning nozzle (14), an outlet port for the exit of spinning mass along an outlet axis (A), and at least one spinning mass flow channel for guiding at least one spinning mass to be extruded from the inlet port (12, 13, 14) to the outlet port, wherein at least one spinning mass flow channel comprises a flow manipulation section having an inlet and an outlet, which comprises a flow-guiding structure (18, 19, 20) for influencing a spinning mass flowing through the spinning mass flow channel, wherein the flow-guiding structure (18, 19, 20) is thereby designed to influence spinning mass flow such that the spinning mass flowi

Abstract: A system for attaching a welding face member to a hard hat includes a hard hat and an adapter. The adapter is attached to the hard hat. The adapter includes an adapter mating member which attaches to a welding face member. The adapter mating member is located below the hard hat.

Abstract: An air barrier that prevents entrainment of surrounding air from the welding environment into the welding helmet is provided. The barrier for the welding helmet contains a flexible curtain, front and rear edges, and means for securing the front edge of the curtain adjacent to the rear edge of the helmet. The flexible curtain may be made of fire-resistant and flexible molded material. The air barrier may be permanently secured to or removable from the welding helmet. The invention may be used in conjunction with a variety of ventilation and cooling systems, including small units that mount on or in welding helmets, as well as more elaborate blowing systems partially carried by the welder.

Abstract: A weld recording system mounted in or on a welding helmet is provided. The weld recording system includes a camera assembly unit, a power supply unit, a processor, and removable memory. The weld recording system interfaces with lens control circuitry, an optical sensor, a welding power supply, and a helmet position sensor. Logic is provided for the triggering and recording of video and audio signals, which are eventually stored in a file for future reference. Transmission of signals from one or more welders to a monitoring station for eventual display is presented. An image processing algorithm is provided to combine multiple images with varied exposure times into a visual image of the weld and its surroundings.

Abstract: An apparatus and method for collecting whole blood and then separating it into components for subsequent use or storage. A self-contained bag set is used to collect the sample, which may then be placed into a device adapted to fit into a centrifuge for separation of components. Each component is then sequentially extracted according to density, with a sensor present in the device to control the operation of valves directing the collection of each component. The sensor may be reading one or more of the following characteristics: infrared, optics, density, weight, radioactive, fluorescence, color, magnetism, ultrasonic, capacitance wherein the characteristic is inherent in the blood and blood component or is an additive. Each component may then be separated into its own storage container. The preferred sensors include optics and weight.
