20150298899 | Fill System and Method Using Storage Container with Rotary Sifter Plate for Adhesive Solids - A fill system retains and transfers adhesive solids of different types and compositions to adhesive melter(s). The fill system includes a storage container for holding a bulk supply of adhesive solids and a separating element such as a sifter plate for moving relative to one of the surfaces of the bulk supply. A drive rotates or otherwise moves the sifter plate against the surface of the bulk supply to separate a flow of fluidized adhesive solids from the bulk supply and then controllably deliver this flow to one or more pumps feeding the melter(s). When the drive stops rotating the sifter plate, the flow of fluidized adhesive solids is stopped from moving out of the storage container. Thus, the fill system provides adhesive solids on demand to pumps and reduces the risk of pumps being starved for air or clogged with coalesced masses of adhesive. | 10-22-2015 |

The nozzle may include first and second air shim plates, an adhesive shim plate and first and second separating shim plates. The first and second air shim plates each have respective pairs of air slots. Each air slot has a process air inlet and a process air outlet and the air slots of each pair converge toward one another such that the process air inlets are farther apart than the process air outlets in each pair. The adhesive shim plate includes a plurality of liquid slots each with a liquid outlet. Four process air outlets are associated with each of the liquid outlets. The process air slots are adapted to receive pressurized process air and the liquid slots are adapted to receive pressurized liquid adhesive. The pressurized process air discharges from each group of the four process air outlets and forms a zone of turbulence for moving the filament of liquid adhesive discharging from the associated liquid outlet in a random pattern. | 12-30-2010 |
20100324531 | APPARATUS AND METHODS FOR INJECTING HIGH VISCOSITY DERMAL FILLERS - A method includes inserting a distal end portion of a needle of a medical injector into a skin of a body. An energy source operatively coupled to the medical injector is actuated such that a dermal filler is conveyed from the medical injector into the skin through the distal end portion of the needle. The distal end portion of the needle is moved within the skin during the actuating. | 12-23-2010 |
