Title: Crosslinked polymer compositions and methods for their use
Inventor: BERG RICHARD A
IPC: A61L31/00
Filed: 1996-12-18
Abstract: Crosslinked polymer compositions comprise a first synthetic polymer containing multiple nucleophilic groups covalently bound to a second synthetic polymer containing multiple electrophilic groups. The first synthetic polymer is preferably a synthetic polypeptide or a polyethylene glycol that has been modified to contain multiple nucleophilic groups, such as primary amino (-NH2) or thiol (-SH) groups. The second synthetic polymer may be a hydrophilic or hydrophobic synthetic polymer which contains, or has been derivatized to contain, two or more electrophilic groups, such as succinimidyl groups. The compositions may further comprise other components, such as naturally occurring polysaccharides or proteins (such as glycosaminoglycans or collagen) and/or biologically active agents. Also disclosed are methods for using the crosslinked polymer compositions to effect adhesion between a first surface and a second surface; to effect tissue augmentation; to prevent the formation of surgical adhesions; and to coat a surface of a synthetic implant.

Title: Gradual clothe coloring and decoloring method and apparatus
Inventor: GUERRA PADILLA DANILO
IPC: D06B3/30
Filed: 1998-07-27
Abstract: This invention can be used for any type of fabric able to be dyed or fades. Like the indigo Denim, cotton, polyester, methylcellulose, wool, the mixtures of fabric (coton/polyester) and others. The dyeings applied in this process are the same ones which those used conventionally. The methods of use of dyeing are recommended by the commercial houses which sell these products. All oxidant, reducer or solvent which can transform or extract the color from clothing can be applied in this invention, all depends on the casts and the desired models. In this invention one uses a completely different machine with the machines conventional (rotatory, paddle, etc). The sizes of this machine will depend on the size of clothing, the quantities to be produced, of the quantities of échantillons(1, 2 or more clothing), of the sizes of samples of laboratory (5 g, 10 g, 100 g or more). The machine of this invention is made up: of a container rectangular (can be also square or circulate) with some hole with bottom for the input of water cold, of water hot, of chemical chimiques, of dyeing and the output of these product. In the bottom of the machine, there is also a mixer to homogenize the solutions and a heating to maintain the temperature constant. Moreover, there is a separator between clothing to avoid the contact between the heating and the mixer (insulation). This separator is used to prevent that the latter are mixed. In the higher part is a support which has a movement horizontal where are suspended the clothings. In this invention, the dye and fades it is made by the fast variation of ascent or the descent of the solvent (water) in the interior one of the container; By adding the reactive chemical ones to various speeds, temperature and pH adapted with the conditions of dye or fades. The expenditure of dyeings is generally lower than 30% of the traditional costs, as the remainder of the reactive ones. However, our machine can be adapted to work by leaving the liquid without movement and by introducing this time clothing into the solution or still by coming out this one. We do not use this technique by its lack of fickleness and its costs high, but it is necessary to be conscious that it can also be used in a possibility. This invention be accompany of new concept of dye and of fade which be The EVOLUTION AND THE MULTI-EVOLUTION, the creation of a NEW TYPE OF MACHINE and probably the birth of a new technology which depend of interest of public, of profit commercial and of attraction of this news mode.

Patent CA-2277334-A1 (CA)
Inventor: SIMPSON RON C
IPC: H04N3/233
Filed: 1997-12-05
Abstract: Unlike previous methods for controlling functions in a video monitor where switching is timed and controlled by monitoring the retrace voltage level, the system of the present invention monitors the change in direction of current in the retrace tuning capacitor. The apparatus of the present invention comprises a small bead inductor (72) placed in the current path of a horizontal retrace capacitor (48) within the horizontal deflection circuit of the CRT device. Measuring the voltage across the bead inductor allows a very precise monitoring of the current through the retrace tuning capacitor. By designing the size of the bead inductor as disclosed, precise electrical pulses can be generated and detected during the retrace time of the CRT electron beam. The invention also minimizes left-side ringing due to the addition of the bead inductor to the horizontal deflection circuit, which lowers the stray resonant frequency within the horizontal deflection circuit.
