Abstract: An extendible surveying probe comprises two collinear position detecting units that allow the probe to be used in an inclined position for accessing vertically inaccessible points with a tip thereof. The two position detecting units may consist of two GPS or GLONASS units used in association with another GPS or GLONASS unit installed on a known point or, alternatively, of two corner cubes used in association with a ground total station. The position detecting units provide spatial coordinates of two spaced-apart collinear points which may be used to extrapolate the coordinates of the point in contact with the tip of the probe.

Title: Operation of a vertebral axial decompression table
Inventor: DYER ALLAN E
IPC: A61F5/045
Filed: 1998-10-29
Granted: 2008-07-22
Abstract: A vertebral axial decompression table is operated by applying a baseline tension to the two table parts, increasing tension to about 50 % of maximum above baseline, then logarithmically increasing tension to maximum tension. Thereafter, tension is linearly relaxed back to baseline. This cycle is repeated a programmed number of times to effect a therapy session. Data concerning the table operation is transmitted to allow remote monitoring and re-programming of the table.

Abstract: The present invention relates to a method for minimizing hydrogen halide corrosion in quench gasifier during the non-catalytic partial oxidation reaction of a halogen-containing hydrocarbonaceous feed, to produce a hydrogen halide-containing synthesis gas, finely divided particulate solids, and a nontoxic slag. The hydrogen halide-containing synthesis gas is contacted with water in the quench zone (14) of the gasifier (10). The quench water contains a neutralizing agent, in excess of the amount necessary to neutralize hydrogen halide acids present therein, to thereby form halide salts. The quench water containing the halide salts is purified to recover the halide salts. The salt-free water is essentially environmentally non-toxic and can either be recycled to the process or discarded in conformity with environmental regulations.

Title: Apparatus and method for managing data storage
Inventor: FRADETTE ROBERT J
IPC: G06F3/06
Filed: 1999-10-04
Granted: 2005-12-20
Abstract: A data storage managing apparatus is described which translates a host Input/output (I/O) request into a standard form. Thus, I/O requests sent by different hosts using different protocols are treated in the same manner for accessing the data storage. The I/O request in the standard form is then normalized by adding a storage address. The normalized request is routed based on the storage address. Therefore, the present invention enables transparent communication between various types of hosts and various types of storage devices.

Abstract: An apparatus and method for forming a complex-shaped frame member from a blank tube (20) having opposed ends are provided. The blank tube is placed in a first cavity (22) on a lower die (12). An upper die (14) is lowered from an open position to a close proximity to the lower die. The upper die has a second cavity (24) aligned with the first cavity. A pair of sealing units seal (32) the opposing ends of the blank tube, and a fluid delivery means for communicating a fluid into the tube. A fluid control means (56) pressurizes the fluid in the tube to a low pressure level.

Le caillot est automatiquement enlevé en réponse à un signal d'obstruction (B) par la modification du cycle de pompage normalement utilisé pour pomper le liquide. Le cycle de pompage est notamment arrêté après un temps de compression (PMB'-PMH) afin d'appliquer une haute pression soutenue à l'intérieur du tube obstrué en utilisant le même liquide et la même pompe pour expulser le caillot du tube. On dérive le signal d'obstruction (B) en mesurant la pression influencée par la viscosité (C). Ainsi, si la pression demeure élevée, il est possible de déterminer de manière fiable un état d'obstruction, qui peut être causé par un caillot.
