Abstract: A method is disclosed for operating a machine tool which comprises a spindle rotatable about a spindle axis; a spindle gripper, carried by the spindle, for gripping workpieces; and a cradle apparatus that can be pivoted back and forth about a pivot axis of the cradle apparatus extending approximately perpendicular to the spindle axis. In the method, the cradle apparatus with a clamped workpiece is set up in a first position, whereupon the clamped workpiece is removed from the cradle apparatus and held with the spindle gripper. The empty cradle apparatus is then pivoted into a second position, and/or the spindle gripper holding the workpiece is pivoted about the spindle axis. Lastly, the workpiece held by the spindle gripper is inserted back into the cradle apparatus, and the latter is pivoted into a further position for further machining of the workpiece that is once again clamped in.

Abstract: An automatic shrink shock strut for use in conjunction with aircraft landing gear. The landing gear is of the type which includes a shock strut cylinder and a shock strut piston mounted coaxially therewith, and defining there between a shock strut shrink chamber filled with hydraulic fluid and a gas spring chamber filled with a pressurized gas. During retraction of the landing gear, the mechanism transfers the pressurized gas from the gas spring chamber to a transfer cylinder and therein drives a volume of hydraulic fluid from a hydraulic fluid supply in the transfer cylinder to the shock strut shrink chamber. The shock strut responds by shrinking to a shortened length. During extension of the landing gear the mechanism returns works in reverse and returns the pressurized gas to the gas spring chamber to drive the volume of hydraulic fluid from the shock strut shrink chamber back to the hydraulic fluid supply, thereby extending the landing gear to its normal length.

Abstract: A method and apparatus are provided for differentiating cells in an automated particle analyzer, such as for use in hematological analysis, by measuring apparent cell size (or volume), membrane integrity and intracellular complexity ("voltaic fragility"). The cells are suspended in a selected reagent mixture including an electrolytic fluid, such as diluent, and if necessary, one or more membrane-modifying agents are selected and mixed in relative quantities in order to selectively alter the membrane structure (i.e., the membrane integrity) of certain cells and thereby enhance cell discrimination. A predetermined dc voltage is applied across a sensing orifice to thereby create a dc electric field within and around the orifice, and the reagent mixture is passed through the center of the orifice.
