A system for converting potential energy into electric power from a mixture of gases, such as atmospheric air, including a particular lesser-density-gas, such as nitrogen, and a particular larger-density-gas, such as oxygen. The system includes a gas-separator at an upper-elevation; a gas-flow-conduit that has a gas-exit-port at a lesser-elevation, where the lesser-elevation is significantly lower than the upper-elevation; and an energy-converter positioned on the gas-flow-conduit. The gas-separator is coupled to the gas-exit-port via the gas-flow-conduit. The gas-separator separates the particular larger-density-gas from the gas mixture. The gas-flow-conduit conducts the separated particular larger-density-gas from the gas-separator via the gas-flow-conduit to the energy-converter; and the energy-converter generates electric power from the conducted separated particular larger-density-gas.

A hollow multi-layered container comprises: an outer layer including a label and an inner layer, which is injection molded. The label has a barrier material that impedes one or more substances that emanate from a product from penetrating through the label, and the label displays information related to the product. The inner layer and the barrier material of the outer layer are substantially coextensive. For a container having a sidewall and an inclined shoulder extending inward from the sidewall, the label includes a primary segment covering the sidewall of the container and a plurality of shoulder pads covering the shoulder in at least approximately contiguous alignment with adjacent said shoulder pads. A method of inserting an in-mold label for an injection molded product into the mold, comprises the steps of: (a) inserting the label partially into a cavity bounded by a cavity mold part so that one end of the label extends from the cavity; and (b) upon closing the mold, pushing the label fully into the cavity by pushing against the label with a mold part that is moved toward the cavity when the mold is closed so that when the label is fully within the cavity, the lateral edges of the label are aligned with each other.

A hollow injection-molded product has a sidewall that is formed in a mold cavity by injecting molding material. An interior surface of the sidewall includes at least one ridge that is shaped by a flow channel in the mold cavity. The flow channel directs the flow of the injected molding material in the mold cavity. The cross-sectional dimension of the ridge normal to the direction of flow of the molding material that is injected in the flow channel generally decreases in the direction of flow. A label is inserted into the mold cavity prior to injection of the molding material so that the label is on the exterior surface of the sidewall of the hollow product.

In an energy conversion system, a flexible conduit is disposed on the outside of a high rise of terrain drawing a stream of heated air through the conduit from a low to a higher elevation, a support structure supports the flexible conduit to maintain a substantially uniform cross-sectional area of the conduit orthogonal to its longitudinal axis. A plurality of longitudinal sections are included that individually include a plurality of lateral modular segments disposed orthogonally about the longitudinal axis of the conduit to laterally enclose the interior of the individual section of the conduit. The conduit has an interior surface of a repetitive varying contour that reduces friction between the interior surface and the air that flows through the conduit.

The dimensions of a portion of an injection molded hollow product formed in a mold cavity between a first cavity surface of a cavity section and a first core surface of a core section are adjusted by adjusting the position of the first cavity surface relative to the position of the first core surface so that the first cavity surface and the first core surface are in a selected relative position when the cavity section is combined with the core section and a protractible and retractable core part is protracted so that a cavity abutment mold part can be connected directly to the protracted core part and the cavity abutment mold part also can be connected indirectly to the protracted core part by a series consisting of abutting mold parts. This series includes a pair of abutting rotatable eccentric rings, which are rotated to adjust the relative positions of the first cavity surface and the first core surface.

A wall section of a coherent product, such as a container, includes at least two opposing plastic components. At least a first one of the opposing plastic components is injection molded and includes a wall of non-uniform thickness that defines some ribs and a web located between two of the ribs in a portion of the wall where the wall is less thick than in the ribs. At a cross section of the first plastic component, over the height of the ribs the predominant thickness across each of the two ribs is significantly thicker than the thickness of the web. At least the crest of a portion of the ribs of one of the plastic components directly or indirectly contacts another plastic component, and at least a portion of the web of the one plastic component is apart from the web of the other plastic component.

In a method of injection molding a plastic product having a base wall and a sidewall (), wherein plastic injected into a base-wall section of the mold cavity is conducted through a flow guide () in the base-wall section and thence into a sidewall section () of the mold cavity, a portion of a base-wall section flow guide is shaped by partially opposing a row of successive recesses () in a first mold part with a series of successive recesses () in a second mold part, with the recesses in the first mold part being so staggered with respect to the recesses in the second mold part as to provide a chain of overlapping recesses that form a sequence of variable-opening throttles () having openings that can vary whenever the alignment between the first and second mold parts varies. The recesses () in the second mold part are more than the recesses () in the first mold part.

A hollow plastic product with a substantially tubular section, two open ends and a thread at the outside of one end of the product is removed from a core mold part by closing the threaded end of the molded product and injecting compressed air into the molded product to loosen the molded product from the core mold part. The threaded end of the product is closed by attaching a threaded closure having a matching thread onto the threaded end of the molded product. A robotic arm is used to robotically attach the threaded closure onto the threaded end of the product. The threaded closure is a plastic cap that injection molded in the injection molding system in which the product is injection molded, with the caps being injection molded at the same average rate as the products are injection molded.

During injection molding of a plastic product having a base wall and a sidewall, fluid plastic material is injected into a base-wall section of a mold cavity. The base-wall section of the mold cavity includes at least one flow guide that is defined by a first mold part, a second mold part, and a third mold part that is movable relative to the first and second mold parts to either decrease or increase the conduction of injected plastic material through the at least one flow guide. Conduction within the at-least-one flow guide is adjusted dynamically while the injected plastic material is being conducted into the sidewall section of the mold cavity by moving the movable third mold part in response to sensed variations in injection pressures in different portions of the sidewall section of the mold cavity.

A system for remotely logging into a personal computer includes a controller coupled to the personal computer and a remote control device. The controller memorizes a login password for the personal computer. The remote control device transmits a login signal to which the controller responds by causing the personal computer to be turned on and by sending the memorized login password to the personal computer. When the personal computer is located in an automobile that includes apparatus for adjusting at least one component of the automobile to provide a plurality of arrangements of the at least one component, the controller controls the adjusting apparatus and memorizes at least a first component arrangement associated with the personal computer; and the controller responds to a first component arrangement signal received from a location remote from the controller by controlling the adjusting apparatus to provide the memorized first component arrangement.

During injection molding of a plastic product having a base wall and a sidewall, alignment of the mold parts that shape the mold cavity is maintained by conducting injected plastic material through a sequence of variable-opening throttles in a base-wall-section flow guide of the mold cavity. The openings of the throttles vary in response to variations in the thickness of a region of the sidewall section into which injected plastic material is conducted from the base-wall-section flow guide so that upon an increase in the thickness of such region the openings of the throttles in the base-wall-section flow guide decrease and so that upon a decrease in the thickness of such region the openings of the throttles in the base-wall-section flow guide increase.

A hollow plastic product with a substantially tubular section, two open ends and a thread at the outside of one end of the product is manufactured by injection molding a plastic product with a substantially tubular section, an open end, a closed end and a thread at the outside of the closed end. An inner core of the core mold part is retracted from within the end of the mold cavity in which the thread is formed so that when the molded product is removed from the cavity mold part, the neck is compressed to partially occupy the region vacated upon removal of the inner core, whereby the thread is removed without damaging the thread. Removal of the molded product from the core mold part is at least helped by injecting compressed air into the closed end of the product. The closed end is then opened.
