摘要:
A process of using solutions containing thiosulfate and/or chloride salt reagents to remove SO3 and H2SO4 acid gases from a flue gas. The solution is injected into a moving volume of flue gas to achieve a droplet size that enables the solution to dry on contact with the flue gas, generating dried particles of the reagent that react with the SO3 and H2SO4 acid gases yielding a salt precipitate. SO2 present in the flue gas may also be absorbed with the solution, with a subsequent reaction yielding bisulfite species that, upon drying of the droplet, react with the SO3 and H2SO4 acid gases to form salts that are removed from the gas. The removal of these acid gases from a flue gas reduce corrosion of equipment used in coal or oil fired power plants downstream of the injection cite.

摘要:
A wrap dispensing apparatus for wrapping an article with wrapping material that includes a base; a hub assembly; a threaded spindle mounted to the base and the hub assembly; and a brake assembly to control the movement of the threaded spindle. The threaded spindle supports a roll of material between the base and the hub assembly. Further included is a steering arm that is attached to the base and the hub assembly. The steering arm is spaced from said threaded spindle. Lastly, the base has wheels for omni-directional movement along a horizontal surface.

An apparatus for controlling a fiber processing plant including a series of processing stages in order to supply fibrous material as a product with predetermined qualities, whereby the qualities of the product can be influenced by suitable, selectively adjustable treatment of fibrous material during its passage through the plant and whereby in at least one of the intermediate stages of the plant an ascertainable quality of the product of this stage is determined. In this intermediate stage a signal is obtained which is equivalent to the ascertainable quality and which is used for controlling the previous stages.

A grain cleaner having a plurality of cleaning sections radiating outwardly from a grain inlet. Each cleaning section has upper and lower downwardly sloped screens over which grain flows by gravity to sift out fine foreign material. Upper and lower foreign material chambers underlie respective screens, and external bypass ducts bypass foreign material from each upper chamber to an associated lower chamber of each cleaning section. Each lower foreign material receiving chamber communicates with a centrally located foreign material discharge outlet at the bottom of the cleaner.

A portable mixing apparatus has a carriage assembly with at least a platform section and an upwardly extending handle section connected thereto, and the mixing apparatus can be manually moved. At least two roller assemblies having roller members therein are mounted on the platform section in predetermined spaced relation to each other for operative association with a bearing assembly which is preferably mounted for limited linear floating movement in the handle section, and with the outer surface of a mixing bowl to be mounted on said roller members. An axle extends from the closed end of the mixing bowl and when the mixing bowl is mounted in the roller members the axle will be aligned with and can be detachably connected in the bearing assembly so that the axis of rotation of the mixing bowl is substantially parallel to the plane of the platform. At least one roller member is disposed in driving engagement with said outer surface of the mixing bowl generally adjacent the closed end, and a drive assembly mounted on the mixing apparatus has a driving motor on the underside of the platform section which is connected to the driving roller member so as to provide a desired optimum speed of rotation for the mixing bowl.Additionally, the above described portable mixing apparatus may have wheels connected to the platform section, and front and rear legs in operative association with the platform section, to permit the mixing apparatus to be pivoted about the axis of the wheels for discharging mixed material from the open end of the mixing bowl.

A connector for a disk drive unit includes a base, a curve portion, a tab, a support, a hook, and a first spring arm. The base has a left portion, a right portion, a bottom portion, and a top portion. The curve portion extends from a back of the top portion of the base. The tab is adapted to be inserted into a retention opening of a static wall of a server. The support extends substantially horizontally from an opposite end of the curve portion, and is adapted to flex up and down when the tab is inserted into the retention opening of the static wall of the server. The hook is physically connected between the support and the tab, and is adapted to flex the support when the hook pressed into contact with a top of the retention opening, and to snap fit around the top of the retention opening when the connector is completely inserted into the retention opening. The first spring arm extends toward a center and in front of the base, and is adapted to apply a force to the static wall when the hook is snap fitted around the top of the retention opening to secure the disk drive unit within the server.

The invention relates to a hand controlled cleaning apparatus used to clean away debris from a boat hull. The apparatus includes a brush at one end that is rotated by either an engine or an electric motor. The user controls the brush with an extended arm portion that may house a flexible shaft or conduits for power. The brush rotates in a direction that makes the apparatus more buoyant during use and gains better traction against the boat hull.

The apparatus permits establishment of measuring values, yielding measuring values being representative of the material cross-section area solely of fiber slivers. A through-put duct converging, as seen, in the direction of transport of the fiber sliver is used into which two pressure measuring ducts merge at two measuring points at which the duct diameter is different. The two measuring ducts transmit measuring signals which are further processed in a division circuit means, which yields an output signal. The output signal is used for fiber sliver control or measuring purposes on machines processing fiber slivers or on spinning machines processing such fiber slivers further.
摘要:
The method is used for producing measuring values depending on the linear density of a fiber sliver transported through a measuring funnel. A measuring signal transmitted from the measuring funnel is transformed into a proportional electric voltage signal and is continually integrated. The apparatus comprises a measuring funnel connected pneumatically with a pneumatic/electric transducer which transmits a signal to an integration circuit means. A control logic which cooperates with a gear of the transmission of the spinning preparatory machine is connected with the integrating circuit means via a proximity initiator which transmits an impulse to the control logic at each passage of a tooth. The integrating circuit means supplies measuring values suitable as a control signal for spinning preparatory machines, which signal is independent of the speed of the fiber sliver.
