Abstract: Pouches of flexible packaging material exhibit a tearing zone in the form of a weakness such as perforations or a separation in the material, this in order to be able to remove the contents easily. The packaging material is covered over by at least one film-forming mass, at least in the region of weakness, in order that the package remains closed until the contents are to be used. The film-forming mass may be the decorative printing on the pouch. After packaging, the contents are protected by the pouch and, in order to remove the contents, the pouch may be opened readily by a pulling or snapping movement which causes the covering of film-forming mass to break.

The apparatus and method make use of a take-off plate for removing articles from a mold, which plate may include heat transfer devices for cooling exterior surfaces of the molded articles or preforms, and a system for cooling in a controlled manner interior surfaces of the molded articles or preforms.

Abstract: A process comprises providing a catalyst comprising a support, a microwave absorption material, and a catalytically active phase; heating the catalyst with a source of microwave energy which is absorbed by said microwave absorption material to increase the temperature of the catalyst to a desired temperature; and contacting said heated catalyst with a hydrocarbon feedstock for upgrading same.

Abstract: An automatic welding machine for waterproof sheeting with a pressing device for pressing lap-welded materials, where the pressing device has at least one press roll which is mounted on a shaft that is secured and is provided with an elastic sheathing on the circumference as a press surface on the contact surface of the material. The press roll is mounted by a pendulum bearing on the shaft which is centered with respect to the outside edges of the press surface and permits an additional limited pendulum movement of the press roll with respect to the shaft. The press roll remains parallel to the running gear of the automatic welding machine, but it can execute a pendulum movement on the basis of irregularities in the substrate, so that the pressure remains essentially constant even if the automatic welding machine is arranged at an inclination. In addition, the proposed press roll can also be driven by providing a rotationally fixed entraining unit between a drive shaft and the press roll.

Abstract: A rotatable turret block is mounted on an index molding machine. The turret block includes at least one mold core for forming molded articles thereon at least one face of the rotatable turret block. The molded articles are transferred from the mold cores to spaced track members for retention and cooling thereon, and the cooled molded articles removed from the track members.

Abstract: A plastic article is formed in an injection mold by injecting molten plastic into the injection mold at an elevated temperature, cooling the plastic from the molten condition to a solid condition, and crystallizing a portion of the plastic by slowing down the cooling of said portion.

Abstract: A method for controlling a vehicle drive unit, which comprises a drive engine and a transmission with a continuously variable gear ratio, comprises the following steps: a) the required vehicle acceleration (ASOLL) is calculated from a throttle control lever position (XFP, XHG) and the current speed of travel (VFZ), b) a required transmission variation (IGDSOLL1) is calculated from the required vehicle acceleration (ASOLL) and the current rotation speed (NMOT) of the drive engine, c) a limited required transmission variation (IGDSOLL) is determined from the required transmission variation (IGDSOLL1) such that the engine rotation speed (NMOT) does not fall below a value which depends on the position of the power control element (XEP) of the drive engine, d) the continuously variable transmission is varied in accordance with (IGDSOLL); e) the actuation parameter (XEPSOLL) for the power control element of the drive engine is obtained directly from the throttle control lever position (XFP, XHG).

Abstract: A method for making an oil soluble coking process additive, includes the steps of: providing mixture of a metal salt in water wherein the metal salt contains a metal selected from the group consisting of alkali metals, alkaline earth metals and mixtures thereof; providing a heavy hydrocarbon; forming an emulsion of the mixture and the heavy hydrocarbon; heating the emulsion so as to react the metal salt with components of the heavy hydrocarbon so as to provide a treated hydrocarbon containing oil soluble organometallic compound, wherein the organometallic compound includes the metal and is stable at a temperature of at least about 300° C. The oil soluble additive and a process using same are also disclosed.

Abstract: A spacer grid with H-springs for use in a nuclear reactor fuel assembly is disclosed. In the spacer grid, two sets of intersectional grid strips are arranged in sets at an angle to each other prior to being encircled by a plurality of perimeter strips, thus forming a plurality of four-walled cells individually placing and supporting an elongated fuel rod therein. A plurality of regularly spaced openings are formed on each of the grid strips and perimeter strips at portions corresponding to the cells. An H-shaped spring is set in each of the openings and has a specifically curved rib capable of being brought into conformal surface contact with a fuel rod placed in each of the cells. The H-shaped spring thus elastically supports the fuel rod. Two positioning dimples are provided on each of the strips at positions above and below each of the openings.
