The upper level of the pouring conveyor receives sand molds and conveys the empty molds to a pouring station wherein molten material is deposited therein to form castings. Each mold is provided with a supportive weight and jacket before pouring. After the castings have been poured, the molds are transferred to the lower level of the pouring conveyor for cooling purposes, and then back to the upper level to remove the weight and jacket. The sand molds are then transferred to the upper level of th...

A series of chill mold sections each including a pair of opposed joinder faces each having a partial mold cavity defined therein are arranged to move in an endless path upon a conveyor device during casting. A teeming station and a mold emptying station are located at different points along the endless path of the mold sections and the conveyor device operates to join together the joinder faces of adjacent molds to form a mold cavity therebetween during at least a part of the travel of the mold ...

Precise sensing and controlling of temperature during in-situ testing of a structure used in an integrated circuit by fabricating or placing a heat source element adjacent to the structure and by fabricating or placing a temperature sensing element adjacent to the structure.

A conveyor for a molding machine and a molding machine incorporating the conveyor in which the portion of the conveyor and its driven rollers that run through the pouring station have been shortened such that the pallets extend over the conveyor to shield the conveyor and rollers from molten metal, and in which the rollers are slanted at an oblique angle relative to the intended path of the molds such that the driven rollers bias the pallets away from the pouring line to ensure that pallets carr...

A foundry mold conveyor system for the intermittent movement or indexing of pallets or other mold carriers successively first past a mold receiving station where a foundry sand mold is placed on each empty pallet, then to and through a jacket transfer station where a conventional jacket is placed on each palletized mold, then past a pouring station where each palletized and jacketed mold is poured with molten metal, then back to and through the jacket transfer station where the jacket is lifted ...

A transducer to monitor velocity and direction of movement having a magnetic core with at least three spaced apart poles. Two of the poles include coils which are wired series aiding for connection to an input alternating voltage, which upon current flow create a magnetic field intersecting the path of movement of an object being monitored. The third pole includes a coil in which an alternating output voltage is induced when the monitored object moves. The magnitude of such output voltage varies...

A transducer is provided for fitting over a rotating shaft to produce a magnetic field about the adjacent area of the shaft when the transducer is energized with an a-c voltage. The transducer includes secondary coils which provide an output signal that varies as a function of stresses developed by the loading of the rotating shaft. The transducer output signals are received by a signal processor which in turn provides output signals for indicating the torque, and/or speed of the shaft. In addit...

A current measuring apparatus for measuring a power supply current received by an electronic device includes: a first current supplying unit for outputting a first current which is a part of the power supply current; a smoothing capacitor for smoothing the first current output by the first current supplying unit connected with one end thereof; a capacitor of device side for smoothing the power supply current, electrostatic capacity of the capacitor of device side being smaller than that of the s...

A mold handling system for carrying and transporting sand molds comprises a mold handling conveyor with multiple mold exits to provide different outputs for the sand molds. The mold handling system may include flags which can be used to mark selected molds to segregate the sand molds into different groups. A control system responds to flag sensors and tracks the molds to selectively control output of sand molds through the mold exits. Methods of handling sand molds using a mold handling system a...

An apparatus and method for detecting total voltage of an assembled battery including a number of serially-connected electric cells. Voltages of the respective cells are detected and added up, correlation between the resulting total voltage and a total voltage obtained by detecting the voltage of the assembled battery directly from its terminals is obtained, and a corrective arithmetic operation is carried out inside the device to correct the total voltage obtained through direct detection. The ...
