Abstract: An object transport apparatus (10) is provided for the purpose of transporting an object (19), usually a semiconductor wafer, to various points within a planar circular zone (Z). The transport apparatus (10) includes a motive power subassembly (12) for generating rotational motion and delivering it to an arm subassembly (14) rotating about an elbow axis (20) and, through an eccentric drive subassembly (110) to a hand subassembly (16) adapted to support to wafer (19). The hand subassembly (16) rotates about a wrist axis (21) which is parallel to but displaced from the elbow axis (20) in an independent fashion from the rotation of the arm subassembly (14). The eccentric drive subassembly (110) incorporates complimentary pairs of cam drivers (111, 112) connected by cam linkages (120, 122) to deliver rotational motion from the elbow axis (20) to the wrist axis (21). The apparatus (10) is particularly useful in the semiconductor manufacturing field where it may be used for a variety of tasks, primarily in delivering wafers (19) from one workstation position to another in a precisely controllable manner.

Title: Process for manufacturing a steel strip
IPC: B22D11/22
Filed: 1988-03-18
Granted: 1992-05-13
Abstract: The invention relates to a process and an installation for manufacturing a steel strip with a thickness of 2 to 25 mm. A steel strand (10) with a thickness of 40 to 50 mm is cast in an oscillating open die (2) at a rate of 5 to 20 m/min. The steel strand emerging from the open die, which is not yet completely solidified, is compressed to such an extent that the inner walls of the already solidified strand shell weld together. After the cooling of the steel strand, the thickness of which has been reduced in this way, to 1000 to 1200 DEG C, the strip is rolled out in at least one pass with a degree of deformation of 5 to 85%.

Granted: 1994-06-01
Abstract: The invention relates to a process for the production of thin stretched films with thickness between 0.1 and 20  mu m from polyolefins of ultrahigh molecular weight by dissolving the polyolefin in a solvent, shaping the solution at a temperature above the solution temperature of the polyolefin to a tape, cooling the tape to a temperature below the solution temperature to obtain gelation and stretching the gelled tape. In this process the gelled tape is initially subjected to a preliminary orientation in one direction, under solvent removal, and is then stretched in a direction essentially perpendicular to the direction of preliminary orientation, at elevated temperature, followed by final stretching to obtain the finished thin films. This process makes possible the production of films which are free from pores, that is to say transparant and which posses high Young's moduli, high tensile strengths and favourable values for elongation at break.

Title: A heat insulated pipe element, a pipeline of such elements, and a method of laying such a pipeline
IPC: F16L59/14
Filed: 1988-09-28
Granted: 1993-02-24
Abstract: In certain subterranean heating pipe systems, which will be difficult of access for repairs, it is preferred to apply copper pipelines, which are more expensive than steel pipes but in turn are corrosion proof. By the mounting of so-called rigid systems, i.e. pipes having a rigid insulation foam filling out the space between the inner pipeline and an outer mantle pipe and securing these pipes mutually both radially and axially, it is customary either that possibilities are provided for axial movements of the pipes by mounting of axial compensators or the like, or that the pipes are laid in such prestretched or preheated condition that the pipes can be laid without axial movements occurring by variations in temperature as instead changes of the stress conditions inside the pipes will occur. By the invention copper pipes of annealed copper is used in a rigid system whereby it has proved possible to lay the pipes in a simplified manner, viz. by cold laying without prestretching and without mounting in axial compensators or the like. High compressive stresses may then build up in the pipes when they are heated initially after the mounting, but that will be acceptable over a period of some months, and since the annealed copper has a relaxation capability the stress will relatively rapidly be reduced to an undercritical level.

Abstract: The present invention relates to a method of reducing the concentration of contaminant ions, preferably nitrate ions, in impure water. The method comprises steps of: a) passing the impure water through an ion exchange resin to substitute regenerant ions from the resin for dissolved contaminant ions; b) passing a relatively dilute aqueous solution of wash-out ions through said resin to substitute wash-out ions for contaminant ions bound to the resin and; c) passing a relatively concentrated aqueous solution of regenerant ions through said resin to substitute regenerant ions for wash-out ions bound to the resin. The affinity of the resin to wash-out ions diminishes from being greater than that for contaminant and regenerant ions when exposed to a relatively dilute ionic solution to being less than that for said contaminant and regenerant ions when exposed to a relatively concentrated ionic solution. The method allows simplified ion exchange apparatus to be utilised, since the raw water, wash-out solution and regenerant solution may all be passed through the ion exchange resin in the same direction.
