Patent number: 4361284Abstract: A nozzle for depositing a layer of solid material on a heated substrate, in particular by chemical vapor deposition, comprises three supply chambers for gas, which chambers communicate with three prismatic spaces which converge towards an outlet slot divided into three by two longitudinal strips which are tensioned at both ends and are applied against support surfaces which provide the strips with their respective inclinations centered on the truncated apex of a prismatic cavity which is divided by the strips to form the prismatic spaces. This arrangement enables a uniform spacing of the outlet slots of the spaces to be maintained whatever the length of the nozzle.Type: GrantFiled: November 7, 1980Date of Patent: November 30, 1982Assignee: Societa Italiana Vetro-Siv-S.p.A.Inventors: Reinhard Kalbskopf, Otto Baumberger

Patent number: 4320695Abstract: An air diffuser for spreading and feeding out an exact amount of conditioned air, comprising an inlet 3 and a stationary hood part 6 connected thereto cooperating with an adjustable hood part 7 for variation of a spreading or feeding gap for the conditioned air. A spring 14 is provided between both hood parts, which are kept at a selected spacing by means of an adjusting screw. Said screw extends through the adjustable hood part via an opening with large allowance, so that the adjustable hood part can be tilted such, that a certain enlargement of the spreading gap on the one side is corresponded proportionally by a corresponding diminution on the diagonally-opposite side. Adjusting the screw changes the total flow through the gap. Tilting the hood part changes the distribution of the air without changing the total flow.Type: GrantFiled: May 9, 1980Date of Patent: March 23, 1982Assignee: AB Svenska FlaktfabrikenInventors: Lennart Widerby, Birger Eriksson

Patent number: 4309456Abstract: The surfaces of a recorded disc are coated with a thin layer of lubricant by forming in an atomizer chamber droplets of the lubricant supported in air. The droplets are formed by passing a flow of air through a supply of the lubricant in the atomizer chamber at a rate and pressure such that the air causes the lubricant to be blown into the space above the supply as fine droplets. The air laden with the lubricant droplets flows out of the atomizer housing to a pair of nozzles in a coating chamber. The nozzles direct the air laden with the lubricant droplets onto the surface of the recorded disc which passes between the nozzles. Excess lubricant which does not coat the disc is collected in the coating chamber and carried back to the atomizer housing.Type: GrantFiled: September 23, 1980Date of Patent: January 5, 1982Assignee: RCA CorporationInventor: Brian E. Lock

Patent number: 4270702Abstract: An adjustable orifice fluid knife utilizing a fluid such as air and including a supporting structure adapted to be connected to a source of fluid. A passage network is on the supporting structure terminating in an opening for transmittal of fluid from the fluid source and out of the opening. A nozzle assembly is on the supporting structure in alignment with the opening for directing the flow of fluid therefrom in a controlled high velocity stream capable of acting as a knife. The nozzle assembly includes a fixed plate on one side of the opening at a predetermined angle with respect to the opening. A bar assembly is on the opposite side of the opening and includes an adjustable blade on the bar assembly responsive to adjustment structure to be angularly shifted with respect to the opening and the fixed plate to a variety of different positions along its length thereby providing for a range of orifice sizes along the length of the blade in alignment with the opening for passage of fluid therethrough.Type: GrantFiled: April 26, 1978Date of Patent: June 2, 1981Assignee: Albany International Corp.Inventor: Charles B.
