A pump that includes a rotatable shaft, a material driving apparatus mounted to the rotatable shaft, as well as a conduit in which the rotatable shaft as well as the material driving apparatus are contained, wherein the pump is capable of reliably pumping viscous material through and out of the conduit.

Pumps configured for use with viscous materials containing aggregate

An orthodontic appliance may include an archwire and multiple orthodontic brackets. The archwire may fit within a human mouth and contain multiple male connectors. Each orthodontic bracket may have a configuration that facilitates attaching the orthodontic bracket to a single tooth. Each orthodontic bracket may allow one of the male connectors to be locked into the orthodontic bracket with a snapping action. The male connector may be unable to slide with respect to the orthodontic bracket after being locked in the orthodontic bracket. A manual unlocking action may allow the male connector to disengage from the orthodontic bracket.

A robot may extrude a tower or column. The robot may include an extrusion nozzle, a positioning system, a climbing apparatus, and a controller. The extrusion nozzle may controllably extrude uncured construction material. The positioning system may controllably cause the extrusion nozzle to traverse a perimeter layer of the tower or column. A climbing apparatus may controllably cause the robot to climb. A controller may autonomously: direct the positioning system to cause the nozzle to traverse the perimeter layer of the tower or column; direct the nozzle to extrude uncured construction material during the traverse; direct the climbing apparatus to cause the robot to climb an incremental amount; and repeat each of the foregoing positioning, extrusion, and climbing steps until the extruded tower or column attains a desired height.

Automated construction of towers and columns

A gastrointestinal administration device comprising an elongated tube or track, an anchor and a channel, which allows the proximal end of the tube or track to be wholly secured inside the mouth from where it passes down the lateral oropharynx to the desired site in the gastrointestinal tract. This system may be used to administer nutrients, fluids, medications, nutraceuticals, dietary supplements and/or non-nutrient gastrointestinal stimulants or other therapies directly to a desired site in the gastrointestinal tract in humans and animals for a variety of purposes including novel applications such as weight and glucose control, local administration of medication and storage of a deposit of a therapeutic agent. It may also be used for monitoring of processes inside the gastrointestinal tract.

Enteral fast access tract platform system

A 3D printing system may print a desired 3D object. A fusible powder may fuse when subjected to a fusing condition. A deposition system may deposit portions of the fusible powder on a substrate. A fusing system may apply the fusing condition to the deposited fusible powder. Inhibitor material may not fuse when subjected to the fusing condition. An insertion system may insert a portion of the inhibitor material between portions of the deposited fusible powder after having been deposited by the deposition system, but before being fused by the fusing system, so as to form a boundary that defines at least a portion of a surface of the desired 3D object.

Inserting inhibitor to create part boundary isolation during 3D printing

An automated extrusion construction system may include an extrusion nozzle configured to extrude construction material in a substantially horizontal direction against an elongated and substantially vertical surface. An extrusion nozzle may have a height adjustment mechanism configured to adjust the height of an outlet in response to level deviations in the surface on which the construction material is extruded by the extrusion nozzle. An automated extrusion construction system may include a slicing mechanism configured to controllably slice through the extruded layer.
