  • Patent number: 5074056
    Abstract: A device is provided for removing moisture and small particles of debris from windshield breaks and the like. The device includes a nozzle for discharging air. The nozzle has a shirt portion with a planar edge. A compressed air supply is discharged through the nozzle. A method also is provided for removing moisture and small particles of debris from windshield breaks and the like. The method includes positioning the nozzle having a skirt with a planar edge over the windshield break. Then, compressed air is discharged through the nozzle mechanism. The compressed air has an initial pressure and a central core area. The central core area has a pressure substantially equal to the initial pressure of the compressed air. The nozzle mechanism is positioned such that the central core is directed at only a portion of the windshield break.

  • Patent number: 5074225
    Abstract: A mechanism for feeding solid material, e.g. wood in a wood-burning furnace, has a pair of rollers. The rollers are rotatably mounted, so as to be generally horizontal and substantially parallel to one another. The rollers are spaced apart to permit the solid material to fall between them. Thus, in a furnace, they are far enough apart to permit logs to fall from a store into a combustion chamber, but are also sufficiently close that, in the absence of roller motion, the material tends to bridge between the rollers. A drive is provided for rotating the rollers.

  • Patent number: 5067254
    Abstract: An improvement to a drum drying and mixing apparatus includes a baffle plate arrangement is supported externally of the drum adjacent one end thereof and is inserted longitudinally from that one end into the drum. Baffle plates of the arrangement are disposed in the veil of materials in a drying section of the apparatus. Pivoting the baffle plates about an axis substantially transverse to the direction of the falling material in the veil modifies the veil to create a channel substantially void of material through at least portions of the veil. Hot drying gases moving longitudinally through the veil encounter a reduced resistance to the flow in the channel and divert from movement through the falling materials in the veil to move through the channel within the region of the veil. As a result the heat transfer from the drying gases to the aggregate materials is reduced and the final temperature of the hot drying gases exiting from the drum increases.

  • Patent number: 5067251
    Abstract: A heater equipped pre-trap chamber is provided at the upstream side of the inlet to a vacuum diaphragm pump so that gas products and solvent drawn from a specimen in a drying chamber can be subjected to a separation operation in the pre-trap chamber to remove liquid and readily condensable vapor forms of solvent. This thereby prevents entry of liquid solvent to the pump unit where it could cause damage. The inlet to the pump is located some distance above the outlet from the pre-trap chamber so that any liquid as may carryover in the flow from the pre-trap chambers towards the pump inlet, will return to the pre-trap as a gravity induced back flow. Solvent collected in the pre-trap chamber is heated to vaporize it and pass it out through the pump in that form to the outside atmosphere, making the pre-trap self-cleaning.

  • Patent number: 5063689
    Abstract: A single wire dryer group for a web producing, and particularly a papermaking, machine. A plurality of heatable drying cylinders arrayed in a row. A respective suction reversing roll is disposed between adjacent drying cylinders. An endless support belt for the web to be dried travels alternately over a drying cylinder over the next adjacent reversing roll and then over the next adjacent drying cylinder. Movable bearings support each of the reversing rolls so that the distance between the reversing roll and at least the preceding drying cylinder in the path of the belt is variable. The direction of motion of the berarings is parallel to the central plane joining the axes of the two drying cylinders adjacent the respective reversing roll. The reversing roll has an initial normal position closer to the preceding web supplying drying cyinder and further from the following web receiving drying cylinder. The bearings are selectively also movable over a large distance from the respective adjacent drying cylinders.

  • Patent number: 5054211
    Abstract: An attachment for a hair dryer, to be secured to the outlet end of the hair dryer, to cause air coming from the hair dryer to orbit and diverge, includes a tubular housing having air inlet and air outlet ends, means associated with the air inlet end to secure the housing to the air outlet of a hair dryer, an air deflector within the housing proximate to the air outlet end, the air deflector being mounted for rotation about an axis parallel to the longitudinal axis of the housing, the deflector including opposed angle vanes on the end thereof nearest the air inlet and having an angled deflector on the end thereof nearest the air outlet, so that air from the dryer passing through the housing will flow past the opposed angled vanes and cause the air deflector to rotate and the air will thereafter be orbitally deflected to one side by the angled deflector. Alternatively, the air deflector can be mounted in a hair dryer itself near the air outlet end.

  • Patent number: 5052125
    Abstract: The present invention provides a method and apparatus for supporting a strand. The strand is positioned between a pair of nozzles that are tilted towards each other such that an upwardly directed gas stream issuing from the first nozzle intersects an upwardly directed gas stream issuing from the second nozzle along a line which along with the strand, forms a generally vertical plane. The combined upwardly directed force from the gas streams lifts and supports the strand while the opposing lateral force from each gas stream on the strand tend to reduce and lateral movement and stabilize its relative position.

  • Patent number: 5050511
    Abstract: A system for the destruction of organic waste material such as halogenated organic compounds, and related matter. In one embodiment the waste material is reduced with a gaseous reducing agent such as hydrogen above about 600.degree. C., the gaseous products are condensed and cooled in the presence of an aqueous mist at about 5.degree. C., and condensed organic and aqueous material is collected and the aqueous portion recycled into the condensing and cooling steps. In another embodiment, where acid gases (for example, hydrogen halides) are produced during reduction, the gaseous products are condensed in the presence of aqueous mist at about 85.degree. C. and a major portion of the aqueous mist condenses as acidic water which is collected and neutralized. Remaining gaseous components are then cooled to about 5.degree. C. as in the previous embodiment. In further embodiments, the remaining uncondensed gaseous products are oxidized with a gaseous oxidizing agent at a temperature above about 1000.degree. C.

  • Patent number: 5048147
    Abstract: An apparatus and method are disclosed that aid an accessory of an automobile wash system in being positioned accurately with respect to a particular automobile's width. The system consists of an abutment that is positioned within the path of the conveyed automobile and which will be pivoted out of the path by contact with the automobile. The extent of the pivoting of the abutment from the path of the automobile will give an indication of the width of the automobile. A hydraulic circuit communicates this information to a hydraulic cylinder that controls the positioning of the accessory and can position the accessory to account for the width of the individual automobile. An electronic sensor system is positioned downstream of the accessory and will sense when the automobile has left the automobile wash assembly, at which time the sensor will initiate a signal that returns the members to their original position.
