Title: Quick-drying nail coating composition
Inventor: VALENTY VIVIAN B
IPC: B05D3/06
Filed: 1993-03-16
Granted: 1998-11-24
Abstract: A photo-reactive nail polish coating composition is provided herein that cures quickly upon exposure to low levels of ultraviolet radiation. The coating includ es nitrocellulose, a particularly-specified photo-reactive monomer, a particularlyspecified photoinitiator and a reaction inhibitor, all in particularly-specified amounts, resulting in a product which is compatible with commercially-available nail poli sh of any colour, and which is removable by standard acetone-based polish removers. It is also compatible with every-day chores because it is insoluble in water. The composition is not phototoxic and has very low potential for skin irritation or sensitization. The photo-reactive coating is applied over the wet nail polish, a nd then is irradiated with safe dosages of ultraviolet radiation, causing the nail polis h to dry in a few minutes.

Abstract: The present invention relates to the conversion of tall oil soap to produce crude tall oil. An aqueous tall oil soap solution generated in a kraft wood-pulping process is placed in contact with carbon dioxide under pressure (22), to form crude tall oil and sodium bicarbonate brine. The crude tall oil and sodium bicarbonate brine are then allowed to separate, under pressure (24), into a crude tall oil layer (28) and a sodium bicarbonate brine layer (26). The crude tall oil layer is then separated from the sodium bicarbonate brine layer, again under pressure. The separated crude tall oil may then be further refined to yield fatty acids, resin acids, and other constituents, which are useful in numerous industrial applications, such as in soaps, lubricants, inks, adhesives, and coatings.

Abstract: The diameter of a hafnium insert (44) press fit into the bottom end of a cop-per electrode (42) varies as a function of the level of a current carried by the elec-trode. The diameter is the minimum necessary to support emission at that currentlevel while also protecting the copper body against attack by the arc. The insert (44) is generally circular and preferably extends completely through the bottom wall (42g) to a circulating flow of cooling water at a hollow interior (48) of the electrode. The bottom wall includes an annular recess (42d) in a portion of the copper wallsurrounding the insert. A coolant tube (56) extends into the recess in a spaced rela-tionship to provide a high flow velocity of the coolant over the interior rear surface of the electrode.

Patent CA-2143806-C (CA)
Inventor: TAL ZEEV

Filed: 1995-03-02
Granted: 2005-10-18
Abstract: A device to squeeze out a desired quantity of the pasty contents of a flexible or collapsible tube. The device is an integral structure having two elongated members connected by a frame at both pairs of corresponding ends.    At least one of the elongated members has a resilient tongue integrally attached to its free elongated side and not connected to the frame. The resilient tongue is a U-shaped leaf spring. One side of the leaf spring is integrally attached to the free elongated side of the elongated member. The other side of the leaf spring is free. The free elongated side of the elongated member and the resilient tongue, or two resilient tongues in the case where the two elongated members have resilient tongues attached to them, define an opening that narrows gradually from a relatively wide entrance to a narrow slot. The width of the entrance is correlated to the thickness of the rear end of the tube through which the seal end of the tube is inserted. The width of the slot is correlated to the double wall thickness of the tube.      Pressure is exerted on the walls of the tube to flatten the tube while sliding on it. A constant force is applied on the pressed together, flattened walls of the tube holding the walls of the part of the tube engaged by the slot firmly closed. Separation between the front full part and rear emptied part of the tube prevents escape of the contents of the tube backwards. It also prevents any unwanted sliding of the device along the tube. The resilient tongue or tongues press the walls of the tube together. In this way, desired quantities of the contents of the tube is squeezed out of the tube in the conventional manner by pressing the walls of the front full part of the tube together or by pushing the device towards the front full part of the tube. The device facilitates the use of these widely available flexible tubes. The device also prevents backflow of the retained contents of the tube.

Title: Generating imitation custom artwork by simulating brush strokes and enhancing edges
Inventor: MIZUTANI MASAO
IPC: G06T1/00
Filed: 1995-04-10
Granted: 2008-07-08
Abstract: The precision of an initial image is reduced through image automatic processing in a manner simulating techniques used in the production of a custom art work. The resulting image, although generated without human intervention, has a pleasing, customized appearance which can be desirable to consumers seeking decorative art work.  One way of reducing the precision of the initial image is modifying portions of the image to have more uniform luminance, color saturation, or color hue, producing a resulting image appearing to contain brush strokes. Alternatively, the precision of the initial image is reduced by locating contrast edges in the image, and modifying the luminance along these edges, producing a resulting image in which objects and features are outlined and have an enhanced definition from the background.

Abstract: Les appareils servant à empêcher la formation de glace dans les ouvertures pratiquées pour fins de pêche sur glace qui existent actuellement sont très utiles mais apportent beaucoup de désagréments aux pêcheurs lors de leur utilisation. Ainsi, plusieurs de ces appareils sont munis de composantes chauffantes ou de ballons gonflés lesquels sont insérés dans le trou et doivent être retirés dudit trou à chaque pêche. D'autres appareils ne font que protéger la surface du trou en étant disposés sur la surface de la glace. Enfin, certains appareils gèlent au niveau de leur extrémité supérieure et ce, étant donné sa position trop près du niveau de l'eau. Ainsi, la présente invention remédie à ces inconvénients par sa simplicité d'utilisation en minimisant le déplacement d'air refroidissant l'eau et donc, permet à l'appareil de demeurer dans le trou pour toute la journée de pêche.
