An engine is configured to extract energy from a heat source as follows. A shaft is adapted to be rotatably coupled to a support and rotatable in a first direction. A plurality of vessels is coupled to and arranged about the shaft. At least a first vessel of the plurality of vessels includes a thermally insulative portion and a thermally conductive portion. A plurality of conduits connects the plurality of vessels together. Each of the plurality of vessels is in communication with at least one other of the plurality of vessels via at least one of the conduits. The plurality of vessels is arranged to allow the thermally conductive portion of the first vessel to encounter the heat source. The thermally conductive portion is capable of transferring heat to at least partially vaporize volatile fluid within the first vessel to cause a mass to at least partially move towards a connected vessel located above the first vessel. This produces a gravitational moment that encourages rotation of the shaft and the plurality of vessels in the first direction.

Rotary gravity engine utilizing volatile material and low temperature heat sources

An engine for extracting energy from a heat source, comprising a support, a shaft rotatably coupled to the support and being rotatable in a first direction, a plurality of vessels coupled to and spaced about the shaft, a working fluid provided in the plurality of vessels, and a plurality of conduits connecting the vessels together in a circuitous fluid circuit. Each conduit has an outlet end connected to one of the plurality of vessels, an inlet end connected to another one of the plurality of vessels, and a one-way check valve configured to allow the working fluid to flow out of the one vessel via the outlet end, through the conduit and into the another vessel via the inlet end. The plurality of vessels and conduits are shaped and arranged about the shaft and the working fluid is selected so that when the one vessel is heated by the heat source the working fluid in the one vessel experiences an increase in vapor pressure causing at least part of the working fluid to flow from the one vessel into the another vessel located above the one vessel so as to produce a gravitational moment that encourages rotation of the shaft in the first direction.

An injection molding system is disclosed that utilizes a melt channel wherein at least a portion of the melt channel has a noncircular cross-section for balancing shear in a melt stream of moldable material that flows therethrough. The noncircular cross-section of the melt channel portion may be, for e.g., capsule-shaped, extended egg-shaped, oval, teardrop-shaped, or peanut-shaped. A flow splitter is also disclosed that is positioned offset from a central axis of an upstream melt channel to protrude between inlets of respective downstream melt channels, where the upstream melt channel splits into the downstream melt channels, to thereby create a narrower inlet into one of the downstream melt channels and a wider inlet into the other of the downstream melt channels.

Melt channel geometries for an injection molding system

An injection molding apparatus includes an inlet component, a plurality of nozzles, and a plurality of hoses, each of which is not heated. The hoses are connected between outlets of the inlet component and respective molding material inlets of the nozzles for conveying molding material from the inlet component to the nozzles. Hoses may also be connected between a rail plate and the nozzles for delivering cooling fluid or actuation fluid for an actuator to and from the nozzles. The nozzles may be fastened to a mold plate of the injection molding apparatus, such as by a threaded bushing. A heated insert may at least partially define the mold cavity to heat molding material in the mold cavity.

Injection molding apparatus

A valve pin bushing assembly for an injection molding apparatus. The assembly includes a bushing body for connection to a manifold, a flexible barrier having a first end that is continuously connected to the bushing body, and a valve pin continuously connected to a second end of the flexible barrier. The valve pin extends through a nozzle in a downstream direction towards a mold gate, wherein the valve pin is movable in an upstream direction and in the downstream direction for opening and closing the mold gate. The flexible barrier seals a channel of molding material from an outside space.

A multi-material injection molding machine includes stationary and moving platens holding cores and first and second injection units for delivering first and second molding materials. The moving platen is slidable towards and away from the stationary platen. Further provided is a rotational distribution unit movable between the stationary platen and the moving platen and defining first cavities on one side and second cavities on an opposite side. The first cavities are for mating with cores to define first mold cavities and the second cavities are for mating with cores to define second mold cavities. Also provided are a rotational actuator for rotating the rotational distribution unit and a molding material delivery apparatus for delivering one or more of the first molding material to the first cavities and the second molding material to the second cavities.
