The hood acts as a position sensing element to guide the boom so that the desired spray pattern is put down around the row of trees or bushes without permitting the spray to reach the foliage of the bushes or tree trunks.Type: GrantFiled: June 22, 1978Date of Patent: April 29, 1980Inventor: Verne E. Lehman

Patent number: 4188199Abstract: A process for forming a metal or metal compound coating on a face of a continuously longitudinally moving glass ribbon which comprises the steps of contacting the glass ribbon face while it is at elevated temperature, at a zone along the ribbon path, with a fluid medium containing a substance which undergoes chemical reaction or decomposition to form the metal or metal compound on the face, discharging at least part of the fluid medium against the face in stream formation having (1) a velocity component in the direction of movement of the glass ribbon and (2) an inclination to the face so that the acute or mean acute angle of incidence of the stream formation on the face, measured in a plane normal to the face and parallel with the direction of the glass ribbon movement, is not more than 60.degree..Type: GrantFiled: March 28, 1977Date of Patent: February 12, 1980Assignee: BFG GlassgroupInventors: Robert Van Laethem, Robert Leclercq, Phileas Capouillet, Albert Van Cauter

Patent number: 4123244Abstract: A process of forming a metal or metal compound coating on a face of a glass substrate which comprises the steps of contacting such face while it is at elevated temperature with a gaseous medium containing a substance in gaseous phase, which undergoes chemical reaction or decomposition to form the metal or metal compound on the face, causing the gaseous medium to flow along the face as a substantially turbulent-free layer along a flow passage which is defined in part by the face of the glass, and drawing residual medium away from the face through exhaust ducting into which the flow passage leads.Type: GrantFiled: March 28, 1977Date of Patent: October 31, 1978Assignee: BFG GlassgroupInventors: Robert Leclercq, Phileas Capouillet, Albert Van Cauter

Patent number: 4099482Abstract: A marking apparatus is equipped with a measuring device so that the marking apparatus can make a series of equally spaced marks. The marking apparatus includes an elongated can holder which is adapted to hold an aerosol can of marking material and a trigger for opening the valve of the can to spray the marking material on a surface. The measuring device comprises an elongated rod which is provided with a longitudinally extending slot, and the rod is pivotally and slidably connected to the can holder by a pin or bolt which extends through the slot and a wing nut which is threadedly engaged with the pin. The rod is pivotable between a storage position in which it extends alongside the can holder and a measuring position in which it extends angularly away from the can holder toward the surface. The rod can be releasably locked in either position by tightening the wing nut, and the distance between the end of the rod and the wing nut can be varied by sliding the slotted rod relative to the wing nut.Type: GrantFiled: May 11, 1977Date of Patent: July 11, 1978Inventor: Thomas J. Smrt

Patent number: 4095378Abstract: A device capable of suction-adhering to a wall surface by the pressure of an ambient fluid, and of moving along the wall surface. The device includes a pressure receiver housing made of a rigid or semi-rigid material; a plurality of wheels or endless tracks secured to the housing so as to make contact with the wall surface; a partition connected to the housing and having a free end adapted to make contact with the wall surface, at least the free end being made of a relatively flexible material, the partition being adapted to define a substantially fluid-tight low pressure area together with the wall surface and the housing or together with the wall surface alone; and means for discharging a fluid from the low pressure area. The partition has a portion extending outwardly from the position at which it is connected to the housing, and by a relatively small force, at least its free end can be displaced toward and away from the wall surface with respect to the housing.Type: GrantFiled: December 14, 1976Date of Patent: June 20, 1978Inventor: Fukashi Urakami

Patent number: 4082057Abstract: Methods and apparatus are disclosed for directing a fluid spray against the interior surfaces of a reaction vessel, without the need for operating personnel to enter the vessel, employing orbiting nozzles connected by a conduit to an annular piston assembly all of which are contained in a cylinder housing mounted externally on the vessel. A hydraulic or pneumatic force is alternately applied to one of the piston surfaces, the rate and direction of movement of the piston, and hence the spray nozzles being controlled by the discharge of fluid from the cylinder housing on the opposite side of the piston. In one embodiment the hydraulic pressure used to drive the piston is provided by the same pressurized fluid which is used in the spraying operation.Type: GrantFiled: April 21, 1975Date of Patent: April 4, 1978Assignee: Tenneco Chemicals, Inc.Inventor: Tom F. Hayes

Patent number: 4053108Abstract: An apparatus for applying road marking lines to a roadway which includes a pair of spaced plates movable with the apparatus to guide the line width. The spaced plates are also provided with a gas outlet opening to guide the marking material away from the plates onto the roadway to be marked.Type: GrantFiled: October 7, 1976Date of Patent: October 11, 1977Inventor: Walter Hofmann

Patent number: 4041898Abstract: An apparatus comprises a conveyor for conveying works held to its support members with the desired surfaces of the works to be treated closely arranged in a low; preheating gas burners arranged below the path of travel of the desired work surfaces to heat the works from below during travel; a first metal spray nozzle, a second metal spray nozzle and a fusing nozzle which are arranged in such order above the path of travel of the work surfaces; and heat-resistant metal disks provided beside the metal spray nozzles respectively, each of the disk being rotatably supported and so inclined that the lower portion thereof exposes the desired work surface only and shields the other work portion from the metal spray nozzle. The disks are rotated during spraying operation by drive means. Melted metal such as self-fluxing alloy, etc. is sprayed onto the desired work surfaces only, while being prevented from deposition on the other work portions.Type: GrantFiled: July 27, 1976Date of Patent: August 16, 1977Assignee: Osaka Welding Industrial Co., Ltd.Inventor: Akiyoshi Tajima

Patent number: 4038942Abstract: A system for spraying powder circumferentially around a pipe comprising a yoke engagable with the pipe for more than 180.degree. of the pipe. The yoke has a powder dispenser mounted thereon and means are provided for driving the yoke circumferentially about the pipe. The system also includes a powder suspension device and a blower-suction device providing a stream of air under pressure to the powder suspension device for creating an air-powder suspension therein. The powder dispenser has an inner housing and an outer housing both having openings adjacent the surface of the pipe and arcuately shaped to conform with the curvature of the pipe. The outer housing forms a space around the periphery of the inner housing. A first conduit connects the powder suspension device to the inner housing of the powder dispenser to provide a spray or stream of air-powder suspension to the surface of the pipe.Type: GrantFiled: August 4, 1976Date of Patent: August 2, 1977Assignee: Commercial Resins CompanyInventor: Robert J.
