Title: A process for selecting and handling objects in a computer-aided design system
Inventor: ROSEL SEBASTIEN
IPC: G06T17/40
Filed: 2005-03-11
Abstract: Several elements are displayed on a computer display. The user is provided with a haptic device, for moving a cursor over the display. Distances between the cursor and the various elements are computed; the element with the smallest distance is highlighted on the display. When the user moves the haptic device, the identified element is changed, according to the distance between the cursor and the various elements. The user selects the identified element by actuating a select button. The invention makes it possible for the user to select one of the displayed elements, without having to move the cursor over the element to be selected. No prior knowledge of the shape of the elements is required for carrying out the selection process.

Title: Removal of impurities formed during the production of 1,3-propanediol
Inventor: WEIDER PAUL RICHARD
IPC: C07C29/80
Filed: 2003-10-30
Abstract: This invention describes improvements upon a process for the production of 1,3-propanediol (PDO) wherein an aqueous solution of 3-hydroxypropanal (HPA) is formed and the HPA is subjected to hydrogenation to produce a crude PDO  mixture. One improvement on this process comprises treating the crude PDO  mixture with an acidic zeolite, an acid form cation exchange resin, or a soluble acid to convert the MW176 cyclic acetal to more volatile materials which can be easily separated from PDO by distillation. Another improvement involves removing water from the crude 1,3-propanediol mixture, contacting the resulting mixture with a solid acid purifier at a temperature of from about 50 to about 250 ~C to convert the MW 132 cyclic acetal to more volatile cyclic acetals, and separating the more volatile cyclic acetals from the 1,3-propanediol by distillation or gas stripping.
