Abstract:
A viscoelastic liquid flow splitter includes a flow splitter body having a first bore including a first bore outlet and a first bore inlet, and a second bore including a second bore outlet and a second bore inlet. The bore inlets are substantially parallel to each other and the bore outlets diverge from each other at an angle. The flow splitter also includes a compression fitting having a first and a second tubular portion fluidically coupled to the first and second bore inlets where the tubular portions are configured to fluidically couple to a double barreled viscoelastic liquid dispensing syringe.
Abstract:
The present invention discloses a 3D printing apparatus and method of using a single-printhead to achieve multi-material and multi-scale printing. The apparatus comprises a base, a worktable, a wafer stage, a substrate, a power source, a printhead, and a support. The printhead is provided with a plurality of material inlets, each of which is connected to a different micro-feeding pump; and multiple materials are thoroughly mixed under the action of an agitator after being fed into the printhead, thereby achieving multi-material printing. In the present invention, a macroscopic geometrical shape of a printed object, microstructures in the interior and on the surface of the object are reasonably controlled, and integrated manufacturing of multi-scale structures is achieved.
Abstract:
An assembly is mounted to a soft serve confection freezer. It includes a set of modules in a circular array and separately replaceable in a magazine. Each module supports a container storing a dry food ingredient in particulate form, and has a motor driven product impeller for controlled discharge of particulates from the container to a blender assembly. The blender assembly has a housing and screw-type auger of cooperating configurations and which cooperate with a central passageway for frozen confection flowing from the freezer, to blend solids into the confection and discharge into a customer's container for immediate consumption. Control panel selection of ingredients by the operator according to the customer's order, is provided. Components are arranged to facilitate cleaning. A system for control panel selection by the operator of liquid additives to the flowing confection, is provided to accommodate the customer's order.
Abstract:
The present invention relates to an apparatus for processing materials, a process for mixing, finishing and de-volatizing polyamide to make 66 nylon and the 66 nylon made by this process. The apparatus comprises an agitator section having an outlet adjacent the bottom thereof; a transfer screw disposed adjacent the outlet of the agitator section; a spiral ribbon extending upwardly from the transfer screw; a ring disposed vertically above the spiral ribbon, at least one baffle disposed vertically above the spiral ribbon and connected to the ring and a wall-wiping spur connected to the ring. Preferably, the apparatus has two baffles--an upper one for pumping the material downwardly and a lower one for pumping the material upwardly. The diameter of each baffle is preferably about 80% of the diameter of the agitator section.
Abstract:
The present Plural Component Mixing Head is an important breakthrough in the known plural resin systems using liquid components such as polyesters, epoxies, urathanes, silicone, alkyd, acrylics and the like. It is particularly useful as a Two Stage Mixing Head whereby solid filler additives may now be added to the mixed liquid resins for body, strength, volume or pure economics. The Two Stage Mixing Head for this important purpose consists essentially of a mixing and dispensing unit having a 1st Stage Mixing Chamber for receiving and dispensing into a 2nd Stage Mixing Chamber the mixed plural component liquid resins, and in the 2nd Stage Mixing Chamber introducing and thoroughly mixing additive solid filler components with the liquid resin mix and dispensing the solid filler and liquid resin mix controlled from the 2nd Stage Mixing Chamber for forming and resin setting of the final mix. An important element in this device is a central and single rotor design actuated by a motor for variable speed rotation. This single rotor with mixing and screw means as an integral part thereof controls and effects all the required mixing and assists with the dispensing progress of the mix in both the 1st and 2nd Mixing Chamber as well as a controlled drawing in of the filler material in the 2nd Stage Mixing Chamber. This single rotor, has a rotor ball head that rotates and seals against a circular and centrally hollow bearing seat in the top of the 1st Stage Mixing Chamber which permits sealing as well as centering and rotation of the single rotor and its rotor mixing and screw means which form an integral part thereof. The single rotor is coupled to the motor coupling above the central hollow bearing seat opening and is spring loaded to force the rotor ball upward and tightly against the centrally hollow bearing seat for positive sealing of the liquid resin components in the 1st Stage Mixing Chamber.
