Title: Travel table
Inventor: SGABELLONE TONY
IPC: A47B3/00
Filed: 1993-08-05
Granted: 1998-06-23
Abstract: A folding table is disclosed for use as an auxiliary table for a child or an adult. It is comprised of three modules, each assembled from a blank of cardboard and easily placed in a flat state for storage or disposal. Each of theleg modules (11, 12) is channel shaped and defines an outwardly projecting tongue which is compatible with a passage of the channel shaped top module (10). A plurality of tear lines (34, 33, 32) is provided in the top module for selective adjustment of the width of the table by tearing off the outer part of the panel. A similar system of tear lines (51c, 51b, 51a) allows the tearing offof the sections of the leg modules to selectively adjust the height of the tableto match, for instance, the height of a child seat in a car. The table may be provided with a utensil tray fixedly but releasably secured to the top module (10).

Abstract: The present invention relates to an improved process for providing the production of a glass preform for an optical fiber which includes substantially no bubbles therein and also which has a substantially uniform shape. The process for the production of a glass preform which comprises at least silica for an optical fiber is comprised of producing a body comprising a rod on which fine glass particles are deposited, preferably by a vapour phase reaction and heating the body to vitrify the body under a reduced atmosphere or a vacuum so that the glass preform is produced. The process includes a first heating step of degassing the body at a first heating temperature, a second heating step of shrinking the body at a second heating temperature which is higher than the first heating temperature and which is lower than a third heating temperature, and a third heating step of vitrifying the shrunken body at the third temperature which corresponds to a vitrification temperature of the fine glass particles so as to produce the glass preform.

Abstract: This invention provides a flammable fluid fuelled heater providing a direct opening into the primary combustion chamber to provide an unobstructed view of the fire. Any circulating means such as a fan may be provided adjacent the opening so as to provide an air curtain across the opening. This may limit the flow of air through the opening to reduce overall throughput as well as reducing spillage out the opening. In addition, the artificial log assembly in the fire may be arranged so that at least some of the logs meet collective surfaces at right angles so as to provide a visual continuity into the reflective surface and thereby provide a larger visual appearance to the fire.

Granted: 2007-12-04
Abstract: The present invention provides a fusogenic liposome comprising a lipid capab le of adopting a non-lamellar phase, yet capable of assuming a bilayer structure in the presence of a bilayer stabilizing component; and a bilayer stabilizing component reversibly associated with the lipid to stabilize the lipid in a bilayer structure. Such fusogenic liposomes are extremely advantageous because the rate at which they become fusogenic can be not only predetermined, but varied as required over a time scale ranging from minutes to days. Control of liposome fusion can be achieved by modulating the chemical stability and/or exchangeability of the bilayer stabilizing component(s). The fusogenic liposomes of the present invention can be used to deliver drugs, peptide, proteins, RNA, DNA or other bioactive molecules to the target cells of interest.
