Abstract: To provide an apparatus and method of curtain coating for applying onto a running web a coating solution from a lip top in the form of curtain to form a coating thereon, wherein a fluid is blown to remove excessive deposits of the coating solution that are formed at the edges in the width direction of the coating, and the deposits blown away by the fluid are ejected.

Abstract: A gas wiping apparatus for use in coating a molten metal onto a steel strip. In the apparatus, a chamber, to which a high pressure gas is supplied, defines a multistage uniform pressure space. A lip support unit is associated with a front of the chamber to allow the high pressure gas to flow therethrough, the lip support unit supporting the apparatus against load. Upper and lower lips are associated with a front of the lip support unit to cooperatively define an outlet. The upper lip adjusts a gap of a gas outlet cooperatively with the lower lip, and can be easily installed in a lip support unit while adjusting the gap of the gas outlet stably. Also, edge over coating (EOC) of the steel strip can be prevented without an additional auxiliary nozzle.

Abstract: An air unit for the removal of excess particulate coating material that is present on products which are in a coating machine comprises, for blowing surplus particulate material off the products, at least one suction member for drawing off air, with particulate material present therein, from the coating machine, separating means for removing particulate material from the air drawn off, and circulating means for feeding at least a portion of the air drawn off to the blowing member.

Abstract: Explosive forces are used to fill interconnect material into trenches, via holes and other openings in semiconductor products. The interconnect material may be formed of metal. The metal may be heated prior to the force filling step. The explosive forces may be generated, for example, by igniting mixtures of gases such as hydrogen and oxygen, or liquids such as alcohol and hydrogen peroxide. To control or buffer the explosive force, a baffle may be interposed between the explosions and the products being processed. The baffle may be formed of a porous material to transmit waves to the semiconductor products while protecting the products from contaminants. Various operating parameters, including the flow rate of the fuel and the oxidizing materials, may be positively controlled. In another embodiment of the invention, a piston is used to transmit the explosive force. If desired, an annular space at the periphery of the piston may be maintained at atmospheric pressure to protect against wafer contamination.

Abstract: The interface between a moving conveyor belt and a work piece can be lubricated using an air driven stream of finely divided droplets of a lubricant composition. Droplets of a preferred size are directed by the air stream onto the conveyor with little waste of lubricant off the conveyor. The lubricant provides a very low coefficient of friction and little or no stress cracking in the containers. Using a low pressure and low flow rate air stream in conjunction with a low flow rate liquid lubricant attains the useful particle size in the lubricant add on spray. The liquid lubricant is sheared by the effect of the air flow creating the desirable droplet size and pattern of lubricant on the conveyor.

Abstract: A coating machine for the processing of chocolate and similar masses having a frame and a circularly driven grating belt supported thereon for the reception of the articles to be coated. The grating belt is guided by deflectors and has a tensioning device. Coating machine components are arranged below the upper run of the grating belt. The tensioning device has an extended travel enabling the lifting of the grating belt. A plurality of supports are provided to support the lifted grating belt, the supports including carriers on the frame of the coating machine.

Abstract: An apparatus which is intended to apply butter from a mass thereof in solid condition to a slice of bread. A housing contains a transfer member connected with the housing by connecting structure which supports the transfer member for sliding motion. A plurality of openings extends through the transfer member. The transfer member and the mass of butter are moved into contact to cause a portion of the butter to enter the openings. The transfer member and the mass of butter are separated to sever the butter within the openings from the mass of butter to leave the openings at least partially filled with butter. The slice of bread is supported with a surface thereof to be buttered spaced adjacent and facing toward the openings in the transfer member. Gas under pressure is directed through the openings to propel the butter within the openings outwardly therefrom into contact with the surface of the slice of bread.

Abstract: A method of coating powder particles includes the steps of circulating an air flow containing the powder particles in a dispersed state therein in a cylinder whose inner wall is wetted with a coating liquid to bring the powder particles into contact with the coating liquid on the inner wall, and drying the powder particles thus coated with the coating liquid. An apparatus for coating powder particles comprises a drying chamber including an inner space for drying powder particles on the surfaces of which a coating liquid is deposited while floating the powder particles by an air flow, a powder-particle feeding device connected to the top of the drying chamber for feeding an air flow containing dispersed powder particles into the inner space through a cylindrical path, and a coating-liquid supplying mechanism for wetting the inner wall of the cylindrical path of the powder-particle feeding means.

Abstract: A method and apparatus for enrobing confections with an enrobing material by conveying the confections along a conveying path over which two transversely extending curtains of enrobing material are directed. Between the respective curtains a first downwardly directed air curtain is provided for smoothing a first layer of enrobing material, and downstream of the enrobing device a second air curtain is provided for smoothing a second layer of the enrobing material and to remove excess enrobing material from the confections. A bottom coating station is provided wherein the confections are guided through an enrobing material containing pan to provide substantially complete coverage of enrobing material over the surfaces of the confections.

Abstract: An arrangement for coating articles with chocolate in which a grating conveyor belt receives the articles to be coated. A shaking device is provided in a region below an upper run of the belt for the purpose of shaking excess liquid chocolate off the articles. The shaking device has a grating mounted pivotably in supporting side members, and this shaking grating has two longitudinal members and transverse members. The transverse members extend transverse to the direction of travel of the belt, whereas the longitudinal members extend along the direction of travel of the belt. A drive unit is connected to the shaker grating to pivotably vibrate the grating for the purpose of shaking the belt. This belt is supported only by the transverse members which have a height that is a multiple of the width of the transverse members. The transverse members, furthermore, are round rods and a respective support bar that has a substantially rectangular cross-section.

Abstract: The present invention relates to the food processing device for producing cylindrically shaped foods having pasty flavors therein.

Abstract: A machine is presented which includes a liquid-coating or battering unit associated with a dry-coating or breading unit, the units being useful separately or when combined as described. The battering unit includes a batter reservoir in which an open mesh wire belt under tension travels beneath a submerger wheel so as to gently nip the product and drag it below the surface of the batter. In the breading application unit, the loose breading material is stored in a hopper above which is a flat slider plate over which passes an open mesh wire conveyor belt in its product-advancing run. This belt then passes downwardly after discharging the coated product, to a lower point in the hopper where the belt is inclined upwardly toward the opposite end of the unit at the inlet end of the slider plate. This portion of the conveyor belt is the breading material elevating run and it travels close to an inclined bottom wall of the hopper.
