Abstract: A universal sled for adapting an existing sheet processing station for use with a sheet handling system, a sheet handling system including an existing sheet processing station, and a method of performing the same. The sled is supported on and moveable relative to a platform of the existing sheet processing station. The sled includes a plurality of parallel support surfaces that collectively form a sheet support surface that may be intermeshed with a plurality of parallel support surfaces that form a sheet support surface of a cart, the sheet support surfaces of the cart being intermeshable with the support surfaces of other modules of the system.

Abstract: A heat exchanger (1) consists of a plurality of disks (4) which are assembled to form a heat exchanger block or disk stack (16) and which are formed in each case from sheets (22) joined together in pairs and enclose between them at least one cavity designed as a duct. The cavity is delimited by the insides of the sheets (22). In the duct, an internal fluid flows in the longitudinal direction of the disks (4) and, on the outside of the disks, an external fluid flows transversely to the direction of flow of the internal fluid. Each sheet (22) has elevations (26, 33?) out of the disk plane, which are formed by material deformation and are directed both into the inside of the disk and toward the outside of the disk, the elevations (33?) directed toward the outside of the disk being configured as elongate stamped-out portions.

Abstract: The invention relates to a heat exchanger provided for heating purposes, particularly for a motor vehicle, comprising: a number of parallel pipes, at least one electric heating device (4), which is mounted each time between two adjacent pipes, and comprising a number of fin elements (5) situated between each pair of adjacent pipes and between each heating device (4) and the pipes adjacent thereto. In order to be able to better control the power absorption of the heating devices (4), each heating device (4) comprises two separately controllable heating sections (6, 7). One heating section (6) is placed on one side (8) of the heating device (4) facing one adjacent pipe, whereas the other heating section (7) is placed on an opposite side (9) of the heating device (4) facing the other adjacent pipe.

Abstract: The invention relates to a heat exchanger, in particular a refrigerant condenser, especially for a motor vehicle air-conditioning unit. The heat exchanger is comprised of a block of tubes and fins and of collecting tubes which are arranged on both sides and receive the ends of the tubes, and of a collector which is arranged parallel to a collecting tube. A method for manufacturing the heat exchanger is also disclosed.

Abstract: The invention relates to a skull pot for melting or refining glass or glass ceramics, comprising a pot wall (1), a pot base, and an induction coil (3) which surrounds said pot wall and through which high-frequency energy can be coupled into the contents of the pot. The pot wall is made up of a ring of metal pipes (1.1) which can be connected to a cooling medium, slot-type intermediate chambers being provided between adjacent metal pipes. The pot base has a run-off for the melt. The metal pipes (1.1) that form the pot wall (1) arm short-circuited with each other above the base in order to increase the degree of efficiency of the skull pot and especially, in order to even out the temperature profile of the melt throughout the depth of the melt.

Abstract: A coating material for interior walls and exterior facades has heat reflection and oleophobicity/hydrophobicity, properties. The material is either opaque to visible light and/or contains a material which provides opacity. It includes: a) at least one silane of the formula (I) XaRbSiR14−a−b  (I)  in which X is a hydrolyzable group, R is optionally substituted alkyl, alkenyl, aryl, alkylaryl or arylalkyl, R1 is an organic radical which is attached to the silicon via carbon and carries a reactive group, a is an integer from 1 to 3, and b is an integer from 0 to 2, or a (partial) condensate of this silane, b) at least one infrared-reflecting pigment whose particle size is situated primarily in the range from 1 to 50 &mgr;m, and c) a solvent and/or dispersion medium.

Abstract: The present invention relates to a method and a device for crushing glass bodies, in which the glass body 18 is arranged in a microwave field 4, so that the said glass body 18 is crushed on account of the resulting thermal stresses. In addition, a local plasma 20, which results in further thermal stresses, is produced on the surface of the glass body 18. Since the glass body 18 to be crushed does not come into contact with crushing means, for example rollers or the like, the pieces of broken glass 22 cannot be contaminated by abrasion particles of the crushing means. The plasma 20 permits a rapid and economic crushing of the glass bodies.

Abstract: A method of producing fine medicament particles suitable for inhalation, particles produced by the method and apparatus suitable for carrying out the method. The method comprises contacting a stream or streams of a solution of medicament with a stream or streams of a liquid in which the medicament is insoluble in a confined chamber such that a region of intense turbulence and mixing is formed. The medicament crystallises as fine particles with minimal inclusion of solvent or anti-solvent impurities. The crystallised medicament is separated from suspension by standard techniques. Careful control of relative stream velocity, solution concentration and proportion of solution and anti-solvent in the streams ensures a uniform product.

Abstract: A collecting box of a heat transfer device has a lengthwise partition in a collecting box between two rows of flat tubes. The tubes are designed as multichannel tubes that are divided by at least one lengthwise separating rib positioned at the level of the at least one lengthwise partition into a number of channels that corresponds to the number of collecting chambers. The at least one lengthwise partition is provided with its edge facing the tube ends with recesses with the spacing of the multichannel tubes. The recesses fit over the separating ribs of the multichannel tubes in a shapewise and flush manner and are connected tightly with the outside contours of the tube ends. In preferred embodiments the parts are made of metal and brazed together.
