    摘要: Liquid metal is supplied from the bottom to the top into a casting mold by way of a casting runner and a filling hole arranged at the lowest point of a casting mold. Direct further use of the casting by avoiding formation of a sprue that must be subsequently processed is possible due to the fact that after totally filling the casting mold and only partial solidification of the metal therein, the casting pressure is decreased or turned off, so that liquid metal flows back out of the casting mold only through a return flow channel having a cross section significantly smaller than the cross section of the casting runner. A ram having a face corresponding in size and shape to the outer contour of the casting in the region of the filling hole is pushed at least over the last segment of the casting runner, thus displacing liquid metal present in the last segment into the casting mold sufficiently far in the direction of the mold interior until the fact of the ram aligns with the inner contour of the casting mold.

    摘要: Discarded refrigerators, freezers and like cooling units are relieved of confined supplies of coolant and/or lubricant by transporting them onto a tiltable platform which attracts the cooling units by suction and tilts them until the freshly tapped portion of the normally closed circuit for coolant or lubricant is located at the lowermost point of the circuit. The lubricant or coolant can be evacuated by a pump by way of a conduit which is connected to a tapping tool and discharges into a vessel. Alternatively, the coolant or lubricant is caused to flow from the tapped circuit by gravity to gather in a vessel beneath the tiltable platform. The transporting system for cooling units can employ trolleys and winches with suction cups which lift discarded cooling units from the gathering point for discarded cooling units and remove cooling units from the platform when the lubricant- or coolant-evacuating operation is completed. Several apparatus can be mounted in a common vehicle for transport to and from the locale which is selected for manipulation of discarded cooling units.

    摘要: Apparatus for testing the fitness of the multiple copy sets for handwritten copies. The form set to be tested is placed on an inclined supporting plate and is clamped to the supporting plate by a slotted hold down plate. A writing instrument, which includes a spring loaded writing implement, is carried by a carriage so that the tip of the writing implement contacts the form set through the slot. The carriage is movable so as to move the tip of the writing instrument along the slot. The writing implement is supported so that the tip contacts the form set substantially without pressure in a starting position. As the carriage is shifted in the direction of increasing ascent of the supporting plate the bearing pressure of the tip of the writing implement increases as a function of the path of travel. The test line produced on the different sheets of the set is a measure of the quality of the copies.

    摘要: A combination tool for machining a bore has a tool shaft transmitting a rotational movement and an oscillating movement in an axial direction of a bore to be machined with the tool. A horning tool is arranged on the tool shaft, and a deburring tool is arranged on the tool shaft at an axial spacing to the honing tool in a direction of a longitudinal axis of the tool shaft. The honing tool is configured to move for each honing stroke between a lower position and an upper position wherein a spacing between a lower edge of the honing tool and a lower edge of the deburring tool in the direction of the longitudinal axis of the tool is greater than a spacing of the lower edge of the honing tool to a workpiece surface when the honing tool is in the lower position.

    摘要: A method of and apparatus for measuring the flexural stiffness of a sheet like sample. The sample is placed on an obliquely positioned surface with its upper edge above a horizontal clamping line. The portion of the sample above the clamping line is of sufficient length so that when it is pivoted forward beyond the vertical the top portion of the sample is freely bent outward. The free clamping length of the sample measured between the top edge and the clamping point is then reduced until the top portion of the sample independently pivots back onto the surface. The residual clamping length thereby obtained is a measurement of the flexural stiffness.
