摘要： An apparatus to aid in isolating a medical practitioner from infectious materials found in a patient. The apparatus includes a collector for providing a vacuum barrier around the mouth of a patient to trap aerosols and the like emanating from the patient during a dental procedure. The collector is flow connected to a vacuum source for drawing a vacuum, and gases drawn in by the source are passed through a filter. The collector is ring-shaped to surround the mouth and to allow the practitioner to see into the site of the procedure and is disposable after each operation.

摘要： The device for the opening and mixing of fiber bales contains a bale opening device capable of being lowered on a bale suspended from a bridge-like machine frame which is fashioned in the form of a portal and is capable of travelling along a guide rail, said bale opening device being equipped with a conveying device. A bale opening roll or plucker roll (6) is provided as the bale opening device, its axis of rotation being perpendicular to the direction of movement of the machine frame and its working width being at least 75% of the total width of the machine frame. A suction channel (9) fixedly installed above the bales (B) serves as the conveying device for the fiber material taken from the bales (B).The device is of simple construction and has a usable opening width essentially equal to its overall width and makes it possible to achieve good fiber mixing.

摘要： Ambient and localized sites within a room space are exhausted as required into a single fan unit and exhaust main. Flexible ducts connected to the main are positionable at various site locations and when one is used to for effecting exhaust at a site, the ambient exhaust to the main and the exhaust path of any other flexible duct is closed off so that exhaust flow in the system can enter only through the selected flexible duct thus maximizing the rapidity and facility with which undesirable gases present at the local site can be removed effectively and most economically from the room space.

摘要： A system serves for exhausting and collecting gases, in particular motor vehicle exhaust gases in an assembly or factory hall. A stationary slotted exhaust conduit (18) is provided on one face with an elastic, axial lip seal for guiding in sealed relationship a suction nozzle of at least one carriage (16) which can be moved in the axial direction along guide sections (41). The suction nozzle is connected to a hose and a vacuum is generated in the slotted exhaust conduit (18) through an exhauster. In order to avoid excessively high tensile stresses in the hose and to facilitate the return movement of carriages along a path parallel to an assembly belt, the carriage (16) is provided with a drive motor (94) whose power take-off shaft (95) carries a friction wheel (96) which can be brought into engagement with the guide section (41), and the flux of force between the drive motor (94) and the guide section (41) can be separated and closed, respectively, by an electrically switchable coupling element in the form of an electromagnet ( 100).

摘要： In a method of removing contaminated air by suction, ejector air is blown towards a tangentially directed inlet slot (3) in a cylinder (2a) comprising part of an air extractor (1). The contaminated air is entrained in this way to form a rotating air stream in the interior of the cylinder, said air stream also being imparted an axial movement component as a result of underpressure prevailing in the interior of the cylinder. The cyclone effect of the air stream in the cylinder is used to separate contaminated particles from the air and to deposit the particles on the inside of the cylinder. The air stream can also be caused to pass through a cylindrical filter (11) arranged centrally in the cylinder (2a). Blow-openings (8) for ejector air are suitably located in the vicinity of the end of a tangentially directed cylinder-extension portion (2b). The cylinder can be flushed to remove adhering particles therefrom, e.g. by means of a nozzle which is arranged in the slot (3) and which delivers a tangentially directed stream of liquid.

摘要： A process and apparatus are described for collection of gases and particulates which arise during the feeding of an electric furnace, especially in the manufacture of phosphorus. The collection system for the gases and particulates includes novel explosion panels which are employed in an enclosure that contains the gases and particulates, and the use of such panels also in the ductwork and filter units that conveys and treats the gases and particulates from the enclosure. A further treating system also prevents moisture in the gases and particulates from clogging the filters used to separate the particulates from the gases. Also described is a novel furnace feeding system that can be used in cooperation with the gas and particulate collection system.
