Abstract: The invention or inventions are directed to devices for obtaining samples of an extremely hot liquid, such as a molten material or metal from a supply thereof for analysis.More particularly the invention or inventions involve what may be termed sections, components or members which are so designed and constructed that they can be readily superimposed in different relationships to provide various forms of subassemblies of devices for receiving samples of an extremely hot liquid such as, for example, molten material or metal.

Abstract: The invention involves a device or assembly comprising an elongated rack and a plurality of rods which are readily detachably connectible to the rack for lateral positioning with respect thereto for preferably supporting wearing apparel.

Abstract: The subject invention involves equipment for tracking the sun by utilizing its energy. Otherwise expressed, the invention is directed to what may be termed a solar collector assembly which is operated by the rays of the sun for automatically maintaining the assembly correctly positioned on the sun in order to substantially obtain the maximum amount of energy therefrom when it is available.

Abstract: The invention involves providing a device for sampling molten material which, among other things, comprises a pair of mating sections, each of which preferably has a rear recessed enlargement or head and a reduced front semi-cylindrical extension which when assembled provide a chamber and a tubular formation the latter of which is adapted to accommodate a tube which serves to receive such a material for flow into the chamber.The invention particularly involves providing a tube with a unique form of an entrance.

Abstract: The invention involves providing a device for sampling a molten material and comprises, among other things, a unique holder or support means which serves to support and hold assembled therein a pair of mating sections which cooperate to define a chamber or mold for receiving a sample of such material for subsequent analysis, and includes modified devices.

Abstract: The invention involves providing a device for sampling molten material which, among other things, comprises a pair of mating sections, each of which preferably has a rear recessed head and a front tubular formation, which when assembled provide a chamber and a pair of juxtaposed tubular formations which are adapted to respectively accommodate a pair of tubes, of which one or both may be utilized to receive such a material for flow into the chamber.The invention also involves providing different forms of tubes and a method for making one of these tubes.

Abstract: A displacement measuring device is disclosed that is particularly useful for measuring and remotely indicating the displacement of a piston rod relative to the cylinder of a power actuator of an earth working implement. The device includes a variable resistor controlled by a gearless actuator connected with the piston rod so that the effective resistance of the resistor is varied depending upon the axial displacement of the piston rod relative to the cylinder. An indicator is connected by electrical circuitry with the variable resistor to display the amount of piston rod displacement relative to the cylinder. A plurality of embodiments of the device are disclosed with one disclosed embodiment including a cable wound about a pulley mounted on the rotatable control shaft of the variable resistor with the cable having one end fastened to the piston rod and a retraction spring to maintain the cable taut regardless of piston displacement in either axial direction.

Abstract: The subject invention is directed to a spreader adapted for support in an upper entrance or inlet of a storage facility or bin for spreading and depositing the product in a circular area to a substantially uniform depth and comprises a hopper or funnel for initially receiving the product and an impeller which is propelled or operated by the downward force of the product.

Abstract: A molten metal sampling device is provided with a tubular connector within its rearwardly extending housing to frictionally engage a correspondingly shaped lance. Certain embodiments provide a socket for holding a sample receiver disposed for reception of a sample from the side.

Abstract: The invention involves providing an elongated structure or unit for obtaining a sample of molten material from a supply thereof and in which its rear extremity is designed and constructed to provide an elongated tapered formation for slidably accommodating a lance whereby to facilitate manipulation of the unit for entry into the supply of molten material.

Abstract: The subject invention involves a toy water pistol which embodies improvements with respect to a reciprocal pump therefor for building up pressure against a liquid for ejecting a stream thereof forwardly through a nozzle an appreciable distance; valve means for controlling the flow of the liquid; a source of electricity; light responsive means and lamps therefor for constituting means for illuminating the stream; a buzzer and a switch for controlling the operation of the lamp and buzzer; and a trigger for simultaneously operating the valve means and switch.
