Publication number: 20120324619Abstract: Moisture activated invisible stencil technology is created by applying a moisture blocking agent in accordance with an artwork is applied to a base substrate. The base substrate is preferably fabricated of a moisture absorbing material. When the object is subjected to moisture, moisture wets to the exposed portion of the base substrate and is repelled in the areas where the moisture blocking agent is applied thereon. The wetted portion of the base substrate changes in shade or color to expose the concealed image. The moisture activated invisible stencil technology can be applied for simple aesthetic applications or advanced for applications to identify wet objects. The advanced applications can include warnings for wet roadways, pool decks, umbrellas, etc.Type: ApplicationFiled: June 26, 2011Publication date: December 27, 2012Inventor: James Drago

Publication number: 20050051199Abstract: A multi-use appliance that has the ability to wash and dry dishes, or produce, or can be used as a food dehydrator. The appliance uses various mixtures of hot and and cold water, at varying pressures, in different cycles to wash it's contents. The water temperature can be achieved either by receiving and mixing hot and cold water from a domestic source, or by just receiving cold water and heating the water by it's own water heater. It also can use different means to dry it's contents, through convection, or by use of a fan and it's own heating source. It can also incorporate means to disinfect it's contents. This can be done by injecting a disinfecting agent into the water supply or by an in-line o-zone generator. All this can be done by various preprogrammed cycles, that are either mechanically or computer controlled.Type: ApplicationFiled: September 9, 2003Publication date: March 10, 2005Inventors: JoAnn Drago, James Drago

Patent number: 6471215Abstract: A grease purgeable dynamic labyrinth sealing device is disclosed which includes a stator having an annular engagement flange on a radially inner portion thereof and a rotor having an annular engagement flange on a radially outer portion thereof. The stator annular engagement flange and the rotor annular engagement flange have coacting means for mechanically interlocking the stator and the rotor. In one embodiment, means, such as, for example, a plurality of apertures, are operatively formed in the stator for allowing excess grease applied to the bearing housing to move through the stator and out of the stator such that the grease purgeable dynamic labyrinth sealing device maintains proper position relative to the bearing housing and is rotatable with the shaft.Type: GrantFiled: February 28, 2000Date of Patent: October 29, 2002Assignee: Garlock Sealing Technologies LLCInventors: James Drago, Joel R. Shaw, Jeffrey M. Grudzien

Patent number: 6045546Abstract: Apparatus and method for collecting, processing, and storing blood components, such as plasma. The method involves collecting the blood component in a flexible storage bag manufactured from ethylene vinyl acetate EVA, having a composition of between about 9% and about 18% vinyl acetate by weight of total EVA co-polymer. The EVA bag is sealed, and the sample is frozen in the bag at a temperature of at least as low as -30.degree. C. to form a substantially solid pellet contained in the storage bag. The bag then is fractured and the pellet is removed in its intact, frozen form. The co-polymer bag may have an inner surface with an etched or embossed pattern of sufficient dimensions to permit removal of the plasma in a frozen state from the storage bag.Type: GrantFiled: August 16, 1995Date of Patent: April 4, 2000Assignee: Pall CorporationInventors: James A. Drago, Bruce Kuhlemann, Richard Spielberg

Patent number: 4229299Abstract: Peristaltic pump means for pumping dialysate solution through a dialysate solution flow circuit in a hemodialysis system. The pump comprises four rollers mounted on a rotatable base member with a relatively long segment of flow circuit tubing tensionally extended around the pump head so as to be simultaneously engaged and compressed by at least two of the rollers, the rollers being mounted for longitudinal movement of the points of compression along the tubing during rotation of the pump head assembly to advance dialysate solution through the flow circuit. The disclosed pump means provides a substantially uniform dialysate solution flow rate under conditions of varying dialysate solution negative pressure and is particularly suitable for use in a unitary, portable hemodialysis module of a type adapted for coupling with either a single-pass proportioning system or a batch dialysate solution supply.Type: GrantFiled: March 22, 1978Date of Patent: October 21, 1980Assignee: Hoechst AktiengesellschaftInventors: Steven R.

Patent number: 4221322Abstract: A 2:1 compensating rotor is used in a continuous-flow centrifuge system, thereby allowing the dynamic loading and unloading of biological suspensions and processing solutions in a "closed" fashion without resort to rotary seals. Improved performance is obtained by relieving the mechanical stresses associated with the 2:1 relative motion between rotary components. In zones of high flexural and torsional stress low-friction bearing mounted tube constraint fittings are utilized to minimize tubing loop wear and risk of rupture. Similarly, in regions of high centrifugal force a tube guide insert is utilized to separate and constrain the discrete fluid-carrying tubes, thereby minimizing abrasion induced by the relative motion between the discrete tubes, as well as minimizing abrasion induced by the relative motion between the discrete tubes and the inner walls of the tube guide assembly.Type: GrantFiled: October 31, 1977Date of Patent: September 9, 1980Assignee: Union Carbide CorporationInventors: James A.
