Abstract:
An inflatable pillow for a pool closure system including a first side surface, forming a substantially vertical plane, a first riser surface, the first riser surface substantially vertically oriented, a top surface, the top surface having a first edge and a second edge, wherein the side surface is connected to the top surface at the first edge, wherein the first riser surface is connected to the top surface at the second edge, the second edge extending substantially horizontally, and wherein the top surface is curved such that the first edge resembles an arc extending both vertically and horizontally.
Abstract:
A portal milling machine has an elongated machine bed (10), the longitudinal direction of which defines an X-direction (2) (machine longitudinal direction). Furthermore, the portal milling machine is provided with a portal (20) which is arranged at right angles to the X-direction and has an elongated plan form, the longitudinal direction of which defines a Y-direction (4) (portal longitudinal direction). A milling unit (50) is arranged on the portal (20) so as to be movable in a translatory manner in a first direction and a second direction transversely to the X-direction (2), and a linear guide (14, 16) which leads through the portal in the X-direction (2) and is intended for a slide (30) carrying a work mounting device (32) and movable in the X-direction (2) is attached to the machine bed (10). In plan form, a part of the machine bed (10) projects beyond the portal (20) in the X-direction (2) at least on one side. The machine bed (10), with regard to the portal (20), is offset in the Y-direction (4) toward one longitudinal end of the portal (20) in such a way that, in the region of the angle enclosed between the projecting machine bed part and the portal (20), good accessibility to the working region of the machine in the region of the portal center is ensured from the other longitudinal end of the portal (20).
Abstract:
A device for producing relative motion with two translational degrees of freedom between a spindle means (95, 195, 295, 395) with a spindle which bears the first part of a first pair of parts formed from a workpiece and a tool, and a retaining element for holding the second part of the first pair of parts, has a first base part to which a first part of a second pair of parts which is formed from the spindle means (95, 195, 295, 395) and the retaining element is attached. The movement device furthermore comprises a second base part, and at least one of the two base parts can be moved in a straight line with respect to the other along a linear guide with a first translational degree of freedom. A support for bearing the second part of the second pair of parts is coupled to the second base part to be able to swivel by means of a swivel joint around a swivel axis which is located at right angles to the linear guide such that the second part of the second pair of parts can be moved by actuating the swivel joint with a second translational degree of freedom on a circular path. The reaction forces and moments which are formed in the machining of the workpiece with the tool are accommodated by the swivel joint which is made stiff; this makes it possible to make the drive means for actuating the swivel joint lightweight. The movement device as claimed in the invention is relatively simple to produce, dynamic and moreover has a high ratio of useful working space to the required construction space.
Abstract:
A method for the manufacture of filters in which a filter material in the rm of a continuous web is pre-embossed, perforated with a laser beam, and then pleated. The pleated filter element is fixed in a subsequent operation in an apparatus and the perforated scrap areas and are removed from the filter element.
Abstract:
A multiple-spindle unit capable of being mounted onto an otherwise standard spindlehead in a tool machine. The multiple-spindle unit is driven by the spindle of the tool machine. A changing arm is utilized for connecting the drive member for the multiple-spindle unit to the spindle of the tool machine and thereafter the multiple-spindle unit is mounted on the spindlehead.

This invention relates to transgenic potato plants producing amylopectin-type starch with enhanced retrogradation stability. The invention further provides a method for producing and identifying such transgenic potato plants.
Abstract:
The present invention relates to a process for producing vitamin E by growing organisms, in particular plants, which have an increased tyrosine aminotransferase activity in comparison with the wild type, and to the genetically modified organisms, in particular plants, themselves.
Abstract:
The content of fluoride ions in aqueous solutions of calcium chloride is reduced by contacting with activated alumina. The contacting can be accomplished either as a batch slurry process or a continuous process using a fixed bed. The adsorption rate of fluoride ions by the activated alumina is increased by pre-treating the alumina with either an aqueous acid or a sulfate solution. Spent alumina can be regenerated by washing with dilute caustic.
Abstract:
A phacoemulsification sleeve 10 includes a shaft member 14 attached to a hub portion 18 for attachment to a distal end of a handpiece 12. The sleeve 10 is in communication with an irrigation supply line 22 of the handpiece 12. The hub portion 18 is preferably formed of a flexible material and has an internal volume sufficiently large to prevent ocular chamber collapse upon occurrence of post-occlusion surge.
