An improved dryer exhaust vent assembly for a clothes dryer is disclosed. The assembly includes an exhaust pipe having a variety of features on its external surface that are constructed and arranged to provide a more secured and easier to obtain engagement with commercially available or customized vent tubing. The assembly may also utilize adjustable band clamps or lever actuated collar clamps to further secure engagement of the vent tubing to the exhaust pipe.

A diffuser for diffusing a gas flow within a stack of blanks that are impregnated with a sol-gel solution, the gas flow evaporating a solvent, each blank having a central through-opening, the openings forming a central well, includes diffusion fins extending from a central cavity toward the periphery of the diffuser, each fin having a central through-opening, the openings forming the open central cavity of the diffuser so as to form an upwardly open gas inlet, the cross section of the central cavity decreasing from the gas inlet, the fins extending into the central well, the fins diffusing and homogenizing the gas flow flowing from the central well through the stack.

A battery powered blow dryer having a novel heating element technology that can be powered by an attached battery pack. The heating element includes an infrared light bulb that emits high heat with relatively low power consumption compared to current methods. The present invention patent also describes a unique configuration of battery cells to optimally perform the task of blow drying hair.

A method of treating a soft or hard capsule shell to reduce or alleviate stress in the capsule shell. The method includes a step of heating at least a portion of the soft or hard capsule shell to a temperature above a glass transition temperature of the capsule shell but below a melt temperature of the capsule shell for a time sufficient to reduce internal stress in the capsule shell. The method can be used to reduce cracking of hard or soft capsule shells by application of the heat treatment to the filled capsule shells after fabrication and filling.

A directional air knife, components thereof, and associated methods. The air knife includes a housing that comprises an inlet opening which receives air under pressure into the housing along a first inlet axis. A chamber is defined within the housing and positioned to receive air that passes through the inlet opening along the first inlet axis. A discharge duct is defined by the housing and includes a discharge channel within the discharge duct. The discharge channel is in fluid communication with the chamber which receives the air under pressure. The housing defines an outlet opening through which the air under pressure passes out of the discharge duct. The discharge channel has a second central axis along which the air under pressure flows to the outlet opening and out of the housing. The second central axis is arranged with respect to the first inlet axis at a skew angle.

The invention relates to a treatment system having a treatment line which comprises a single-part or multi-part drying chamber for drying and/or curing coated workpieces, optionally vehicle bodies. An at least two-part drying conveyor device is provided which extends along an at least two-part drying conveyor portion, the drying conveyor portion having at least two conveyor sub-portions, the first conveyor sub-portion having a first conveyor sub-device which is designed as a longitudinal conveyor device, and the second conveyor portion having a second conveyor sub-portion which is designed as a transverse conveyor device. The invention further relates to a treatment method.

In order to provide a treatment system for treating workpiecesin particular, vehicle bodieswhich system has a simple structure and enables energy-optimized and/or quality-optimized workpiece treatment, it is proposed that the treatment system comprise the following: a housing which surrounds a treatment chamber; a cooling gas flow supply for supplying a cooling gas flow to the treatment chamber; and a heating region which is adjacent to the cooling gas flow supply or forms a component thereof and which can preferably be heated to a temperature which is above a temperature of the cooling gas flow.

A method of treating a hard capsule shell to reduce or alleviate stress or reduce the propensity for cracking in the capsule shell. The method includes a step of heating at least a portion of the hard capsule shell to a temperature above a glass transition temperature of the capsule shell but below a melt temperature of the hard capsule shell for a time sufficient to reduce internal stress in the hard capsule shell. The method can be used to reduce cracking of hard capsule shells by application of the heat treatment to the filled capsule shells after fabrication and filling.

A rotary dryer for resin dehydration, comprising: a cylindrical body which rotates about an axis perpendicular to a diameter of the cylindrical body; an air filter located outside the cylindrical body; coils located outside the cylindrical body, wherein the coils are oriented vertically and oriented parallel to the diameter of the cylindrical body, wherein the coils do not comprise horizontal surfaces; and lifters located within the cylindrical body.

A removable insert and a spray nozzle which includes the removable insert and a nozzle cap. The removable insert has a base member and a protruding member. The nozzle cap has an annular flange which delimits an interior locating surface for the insert. The flange extends radially and ends with an internal extremity which defines a planar spray opening. When in use, the base member is housed within the nozzle cap whilst the protruding member projects outwardly and stands proud of the planar spray opening.
