Title: Fitted furniture covers having built-in drainage troughs
Inventor: MULLER JOHN
IPC: A47G11/00
Filed: 1998-09-18
Abstract: A cover for an article of furniture such as an umbrella table assembly or a chaise lounge, provides improved drainage. A portion of the cover associated with an umbrella pole is releasably secured to the pole and maintained in elevated position by the pole to provide a tent-like structure, which includes an annular peripheral skirt depending below the table top. Releasable fasteners for securing a cover to an article secure the cover on the article after the cover has been positioned on the article. The cover extends from the elevated portion at afirst angle towards the table top. The cover is manufactured to provide surfacesthat are inclined at an angle greater than the first angle when the cover is installed, so that the cover better sheds water and other debris.

Title: Local sorting of downloaded tables
Inventor: NIELSEN JAKOB
IPC: G06F3/0487
Filed: 1998-09-29
Abstract: Sorting of table data is enhanced by providing hidden sort keys associated with table cell data. When table data is displayed, the hidden sort keys are not, but they may nevertheless be used as a basis for sorting table information. Thus table data may be presented in a variety of views with alternative arrangements of data, based on whether each column or row of table data is sorted by content or by the hidden sort key or sorted in ascending or descending order. The table may selectively be restored to its original configuration after sorting. Sorting is invoked by interpreting mouse clicks in a header cell of a table column or row.

Abstract: Un ophtalmoscope laser à balayage (10) ayant un large champ de vision donne une image en couleur de la partie interne de l'oeil d'un patient à différentes profondeurs, pendant que l'on présente au patient une cible de fixation destinée à évaluer sa fonction visuelle. L'ophtalmoscope (10) comporte un système d'éclairage (30), un système de capture et de détection (32) et un système de génération d'image cible (38). Les trajets optiques de ces différents systèmes sont séparés par un ou plusieurs diviseurs de faisceau, de façon à ne pas bloquer un rayon principal venant de l'oeil du patient, ce qui évite les effets d'extinction au niveau de l'image capturée. Un système de balayage simplifié comprend un seul dispositif de balayage ayant une surface réfléchissante mobile. Un élément optique passif fixe (74) génère à partir d'un point lumineux une raie lumineuse (76) qui tombe sur l'élément optique, la raie lumineuse étant balayée par le dispositif de balayage selon une direction perpendiculaire à elle.

Title: Axle tilt control method and apparatus for industrial vehicles
Inventor: ISHIKAWA KAZUO
IPC: B66F9/24
Filed: 1998-10-29
Abstract: An industrial vehicle has a body frame and an axle pivotally supported by the body frame.  The vehicle also includes a damper located between the body frame and the axle.  An passage supplies oil to the damper in accordance with tilting of the axle and receives oil discharged from the damper.  A control valve is located in the passage to control oil flow into and out of the damper.  A tilt angle sensor detects the tilt angle of the axle.  A controller controls the control valve in accordance with locking conditions for locking and unlocking the axle.  When the locking conditions are not satisfied, the controller monitors whether the tilt angle of the axle detected by the tilt angle sensor exceeds a predetermined maximum tilt angle.  The controller locks the axle if the tilt angle exceeds the maximum tilt angle, and thereafter unlocks the axle if the forces on the rear axle tend to decrease the tilt angle.

Title: Tubing head spool and method of using same
Inventor: DALLAS L MURRAY
IPC: E21B43/25
Filed: 1999-07-07
Abstract: A tubing head spool for use with a BOP protector in fracturing or stimulation treatments is described. The tubing head spool includes a reinforced area of its sidewall that is adjacent a bottom flange of the spool and surrounds a supports an annular seal which provides a sealing engagement between the end of the BOP protector and a secondary seal in a bottom of the spool.      The reinforced area contains radial pressure transferred through the annular seal during well stimulation treatments. The reinforced area has a pressure rating greater than the pressure rating of the remainder of the tubing head spool so that the modified tubing head spool is adapted for use with the BOP protector for high pressure well stimulation treatments. The advantage is an economic tubing head spool that enables safe high pressure well treatments at pressures up to the pressure rating of the reinforced area of the tubing head spool.

Title: Sandramycin analogs
Inventor: BOGER DALE L
IPC: C07K11/02
Filed: 1998-03-27
Abstract: Analogs of sandramycin (1) are synthesized and shown to have cytoxic activity against various tumor cell types. The relative cytotoxic properties of the sandramycin analogs are approximately parallel to their relative DNA binding affinities. An exception to this generalization is compound (4) which completely lacks the sandramycin chromophore phenol. Although typically 4-10x less potent than sandramycin against leukemia cell lines, compound (4) proved to be 1-10,000x more potent against melanomas, carcinomas, and adenocarcinomas exhibiting IC50 values of 1 pM-10 nM. This activity places compound (4) among the most potent agents identified to date.
