摘要:
A device for metering fluids comprising a fluid chamber with one inlet or outlet port, at least one sidewall and a movable separator that is in contact with and separates the fluid in the chamber from the other components of the device, a porous actuator housing and wicking material, a flexible polymer actuator material in contact with the porous actuator housing and the moveable separator, an actuator hydrating solution reservoir with at least one sidewall, an inlet port, and in fluid contact with porous actuator housing, a fluid gate located at some point between actuator hydrating solution reservoir and the polymer actuator, effectively keeping actuator dry, and an external shell to hold all components so that the polymer actuator can only move in a direction and apply pressure to the separator in contact with the fluid in the fluid chamber, thereby dispensing fluid from fluid chamber.
摘要:
A method of manufacturing products comprising an outer casing of a first material (12) and containing at least one chamber (18) filled with a second material (14) comprises extruding the first material through a die (10) to form an extrudate body (16) and delivering the second material through at least one fluid outlet (22) in the die to form the least one filled chamber. The extrusion process is varied periodically and momentarily to produce sections (30) of extrudate body having no filled chamber. In one embodiment, the flow of the second material (14) is periodically reduced to form the unfilled sections. The flow of the second material (14) may be reduced by increasing the volume of a supply path for the second material upstream from the die (10). Apparatus for carrying out the method is also disclosed. The method and apparatus are particularly adapted for producing food, and especially confectionery, products.
摘要:
The electrically connectable tile module includes a porous substrate having a top side, a bottom side, and at least two side edges. At least one connector is integrated into the porous substrate allowing adjoining electrically connectable the modules to be electrically connected to the porous substrate. At least one electrical element is disposed over the top side of the porous substrate and electrically connected to the at least one connector.
摘要:
Disclosed is a gas generating polymer compound that when irradiated with light or other radiation sources makes a solid to gas phase transition due to chemically catylized degradation, irradiative degradation or both. This provides a low cost, stable and easily manufactured means of gas production. Also disclosed are possible uses for the gas generator such as a low cost micro thruster.
摘要:
An angiocatheter device featuring a catheter body; a stationary anchor disposed in the inner cavity of the catheter body; a channel fluidly connecting the first end of the catheter body and the second end of the stationary anchor; and a compressible valve surrounding at least a portion of the stationary anchor. A hole is disposed in the second end of the compressible valve. The compressible valve can move between an extended and compressed position. In the extended position the second end of the compressible valve covers the second end of the stationary anchor and the hole in the compressible valve is closed preventing fluid transfer from the channel into the catheter body. In the compressed position the compressible valve is compressed such that the second ends of the stationary anchor and channel are accessible allowing for fluid transfer. The compressible valve is biased in the extended position.
摘要:
An actuator housing unit for a system of layered surfaces, comprising an activated primary surface having a physical shape capable of change when activated by an electrical, chemical, or light stimulus, to expand and exert force or pressure or contract and remove force or pressure, upon activation or deactivation, to move or keep matter within the housing by direct or indirect contact.
