    Abstract: A microturbine power generating system includes an electrical generator and a turbine having a fixed inlet nozzle geometry. Maximum thermodynamic efficiency of the microturbine power generating system is achieved by maintaining the turbine inlet at or near maximum temperature. When power demanded of the system is constant, power is supplied by the electrical generator. When an increase in power is demanded, at least a portion of the entire demand is supplied by a battery or other energy storage device until the electrical generator can satisfy the increased power demand. Conversely, when a decrease in power is demanded, the load on the generator is temporarily increased (effectively putting a brake on the generator and turbine) and such load is absorbed by the battery or other energy storage device.

    Abstract: Foundry apparatus for mixing sand with binder ingredients to produce a composite mixture suitable for foundry molds includes a first premixing chamber enclosing a first bladed shaft mounted for rotation about a substantially horizontal first axis operable for conveying and commingling sand with a first binder ingredient to produce a first sand/binder ingredient mixture. A second premixing chamber, separate from the first premixing chamber, encloses a second bladed shaft mounted for counterrotation about a second axis, substantially parallel to the first axis, for conveying and commingling sand with a second binder ingredient to produce a second sand/binder ingredient mixture. A final mixing chamber includes agitators for receiving the sand/binder ingredient mixtures and blending them into a composite mixture while simultaneously transporting the composite mixture to a final discharge station. A single power-driven unit operates for driving the first and second bladed shafts, which in turn, operate the first and second agitators.

    Abstract: An auxiliary system includes a plurality of devices that are driven by ac motors. A plurality of independently controllable isolators couple phase windings of the ac motors directly to phase windings of the electric generator. When an isolator connects the phase windings of its corresponding ac motor to the windings of the electric generator, the ac motor is operated directly on a high frequency unconverted output of the electric generator. Motor speed is determined by the number of poles on the ac motor relative to the number of poles of the electric generator. Pole-switching allows the speed of the motor to be varied.

    Abstract: A pattern holder 12 and a sand tank 14 are rotatably mounted on a frame 16 so that the pattern holder can be inverted over and sealably mounted atop the sand tank. A vented pattern 26 is secured to the pattern holder and forms a first chamber between one side of the pattern and the interior of the pattern holder. A second chamber 90 is formed between the other side of the pattern and the interior of the sand tank when the pattern holder adjoins the sand tank. O-ring seals 32 and 80 isolate the chambers from the atmosphere so that a partial vacuum can be formed therein. A mixture 84 of sand and a gas-curable binder is provided in the sand tank so that the mixture will fall onto the pattern upon inverting the sand tank over the pattern holder. A flexible line 42 is provided for controllably introducing a gas catalyst into the chamber 38 in order to cure a portion of the sand-binder mixture to form a shell mold 94 of a predetermined thickness on a pattern face 36 of the pattern. Flexible lines 41 and 43 are provided for evacuating and purging the chamber 38 at different stages in the process.

    Abstract: A gravity latch for a swinging gates such as a corral gate or a gate on a box stall. The latch has a barrel and keeper mounted on the gate and a gate post. They are both rectangular metal tubes and inclined downwardly from the barrel to the gate at an angle of 45.degree.. The barrel and keeper have parallel rows of fastener openings through them to enable the fastening of the barrel and keeper to gates and posts of various types, including wooden and steel corral gates. A bolt for the latch is in the form of a source metal tube that slides along the barrel and the keeper. In the latched condition, it is completely enclosed within the barrel and keeper to prevent opening of the gate by an animal.
