  • Patent number: 5261931
    Abstract: SO.sub.3 flue gas-condition systems (10) provide a controlled flow of flue gas-conditioning agent such as SO.sub.3 into a boiler flue gas and its entrained particulate material ahead of an electrostatic precipitator (14). The systems (10) monitor the opacity of the stack effluent and precipitator power and operate to maintain a flow of SO.sub.3 -conditioning agent into the boiler flue gas to provide minimal opacity of the stack effluent. The systems operate at SO.sub.3 -conditioning agent flow rate corresponding to minimal opacity of the stack effluent and to eliminate corrections that may be due to transient operating conditions such as boiler upsets, precipitator rapping and the like. The systems include features providing improved conversion of SO.sub.2 into SO.sub.3, integrated assemblies to provide a flow of SO.sub.2 and sulfur dioxide conversion units adapted to convert SO.sub.2 into SO.sub.3 at a plurality of remote SO.sub.3 injection sites.

  • Patent number: 5260743
    Abstract: An electrophotographic apparatus having a first frame accommodating an exposure head which emits a light according to digital image data and a second frame accommodating a photosensitive member on which an electrostatic latent image is formed with a light emitted from the exposure head to the photosensitive member at an exposure portion. The first frame is openably supported by the second frame. When the first frame is opened relative to the second frame, the exposure head is released from the photosensitive member and thereby a document exposing unit including a transport system for transporting a document and an exposure optical system for exposing the photosensitive member to an optical image of the document being transported by the transport system is mountable at the exposure portion.

  • Patent number: 5259723
    Abstract: A feeding device for down hole tubulars includes a frame which defines a support surface. First and second stops are arranged to reciprocate in stop guides between an upper position, in which the stops interrupt movement of a tubular, and a lower position in which the stops allow movement of the tubular. The stop guides are moveable relative to one another to adjust the separation between the stops as appropriate for tubulars of different diameters. A tilting actuator arm cycles the stops between upper and lower positions to control the feeding of tubulars along the support surface.

  • Patent number: 5256027
    Abstract: A lifting apparatus to be attached to a side of a garbage collection truck. The apparatus comprises a series of linkages mounted to a mounting member attached to the vehicle. A plurality of suction cups is provided on a garbage bin securing member. A vacuum supply to the suction cups is actuated by means of a trip switch mounted adjacent to the suction cups. The trip switch is activated as it abuts the side of a garbage bin. The vacuum supply is disconnected as the bin securing member returns past a predetermined position. In a preferred embodiment, the securing member is mounted on lateral shift rails to allow for positional adjustment of the bin securing member relative to the bin. The apparatus is adapted to raise a garbage bin from a position generally adjacent the truck to a raised and inverted position adjacent to an entry chute of a garbage compactor of the garbage truck.
