20090316516 | Adhesive Dispenser Apparatus Having A Mixing Device With A Corrugated Conveying Plate - A dispenser apparatus for dispensing an adhesive containing at least two components includes a mixing device and a header. The mixing device comprises a conveying plate having first and second grooved surfaces each overlaid by a respective cover plate. The conveying plate and opposed cover plates cooperate to define a plurality of separated channels extending through the mixing device. The discharge ends of the channels are interdigitated. | 12-24-2009 |
20090316517 | MIXING DEVICE HAVING A CORRUGATED CONVEYING PLATE - A mixing device for mixing adhesives containing at least two components comprises a conveying plate having first and second grooved surfaces each overlaid by a respective cover plate. The conveying plate and the opposed cover plates cooperate to define a plurality of separated channels extending through the mixing device. The discharge ends of the channels are interdigitated. First and a second distribution manifolds are defined within the mixing device. A supply port adapted to receive one adhesive component extends through a respective cover plate into fluid communication with one of the distribution manifolds. | 12-24-2009 |
20120065592 | DEVICE FOR DISPENSING MICROLITER QUANTITIES OF A MATERIAL INTO A PUNCTURE WOUND SITE - A seal-less, hand-held dispensing device for dispensing microliter quantities of a material at a site of a puncture wound having a predetermined dimension of not less than 0.8 mm comprises: a support platform; first and second hollow members on the platform; and a compatibly sized plunger disposed in each hollow member. The hollow members are positioned on the platform such that a circumscribing circle centered on a point between the hollow members has a diameter that is not greater than about 0.8 mm such that both of the hollow members are insertable into a site of a puncture wound without undue disruption of any tissue matter surrounding the site. | 03-15-2012 |
20120065600 | DEVICE FOR DISPENSING MICROLITER QUANTITIES OF A MATERIAL INTO A LONGITUDINALLY EXTENDING WOUND SITE - A seal-less, hand-held dispensing device for dispensing microliter quantities of a material at a site of a slice wound the edges of which are spaced apart a distance in the range from at least about 0.4 mm to about 0.5 mm comprises: a support platform; first and second hollow members on the platform; and a compatibly sized plunger disposed in each hollow member. Each hollow member has a predetermined maximum outside dimension that is not greater than about 0.4 mm such that both of the hollow members are insertable into a space between the edges of a slice wound without undue disruption of any tissue matter surrounding the site. The largest outside dimension of each compatibly sized plunger being in a range from about eighty percent (80%) to about ninety-five percent (95%) of the largest inside diameter of a hollow member in which it is disposed. | 03-15-2012 |
20120065666 | SEAL-LESS DEVICE FOR DISPENSING MICROLITER QUANTITIES OF A MATERIAL INTO A SITE - A seal-less, hand-held dispensing device includes a support platform having a pair of finger gripping surfaces; first and second hollow members on the platform; and a compatibly sized plunger disposed in each hollow member. Each hollow member has a largest inside dimension in the range from about 0.2 mm to about 0.3 mm and each plunger has a largest outside dimension that is sized for compatible receipt within a hollow member. The largest outside dimension of each compatibly sized plunger is from about eighty percent (80%) to about ninety-five percent (95%) of the largest inside dimension of a hollow member. An actuator having a thumb actuating surface thereon is operatively engagable with each plunger. When fully extended a predetermined maximum finger span is defined between the actuating surface and the gripping surfaces, the maximum finger span being not greater than about 150 mm. | 03-15-2012 |
20120325854 | DISPENSING DEVICE HAVING AN ARRAY OF LATERALLY SPACED TUBES - A device for dispensing individual components of a two-component adhesive includes first and second manifold members, each having a distribution chamber therein. A set of conveying tubes is supported within the dispensing device and collectively present a predetermined total cross-sectional flow area to the first distribution chamber. An array of openings and an array of passages extend through the second member. The openings receive the discharge ends of the conveying tubes. The passages are disposed in fluid communication with the second distribution chamber. The passages collectively present a predetermined total cross-sectional flow area to the second distribution chamber member. The openings and the passages are laterally spaced with respect to each other such that the discharge ends of the tubes are interspersed among the passages. The cross-sectional flow areas presented to the first and second distribution chambers are different. | 12-27-2012 |
20130020352 | DISPENSING DEVICE HAVING AN ARRAY OF CONCENTRIC TUBES - A device for dispensing individual components of a two-component adhesive includes first and second manifold members, each having a distribution chamber therein. A set of conveying tubes is supported within the dispensing device and collectively present a predetermined total cross-sectional flow area to the first distribution chamber. The second manifold member has an array of passages therethrough. Each tube extends substantially concentrically through a respective passage to define annular flow spaces that collectively present a predetermined total cross-sectional flow area to the second distribution chamber member. First and second components emanating from the tubes and the flow spaces are able to intermix with and diffuse into each other on the discharge area of the second manifold member. The cross-sectional flow areas presented to the first and second distribution chambers are equal. | 01-24-2013 |
