Abstract: An elevator system for a structure having a plurality of floors, including a plurality of elevator cars mounted in the structure to serve the floors. The elevator system performs a plurality of functions related to collecting floor or corridor calls, collecting car status and position data, allocating corridor calls to suitably conditioned elevator cars which are already in the process of serving calls for elevator service, creating a demand signal relative to a call which can not be so allocated, and assigning an available car not in the process of serving calls for elevator service to a call for which a demand signal was created. The various functions are performed as the need is indicated for them, with the sequence of their performance, when the need for more than one function is indicated, depending upon their relative urgencies.

Abstract: This invention relates to electron image devices for focusing an electron image derived from a photocathode element onto a target element with a substantially planar surface. More specifically, the photocathode element has an electron emitting surface of a substantially spherical configuration, a cylindrical electrode disposed around the axis of this device and having a diameter of a magnitude in the approximate range of 2.0 to 2.2 times the length of the radius of the photocathode element, an anode element having an aperture therein with a diameter of a magnitude not less than 0.3 nor more than 0.5 times the length of the photocathode radius, and a conical portion extending from the aperture at an angle of approximately 45.degree. with respect to the axis of this device.

Abstract: This invention relates to a method of determining the sequence of die sizes to be used in a multi-die/block drawing machine to draw metal from any given input stock size to any given final wire size to give optimum efficiency and proposes nomograms for achieving the sequence quickly and easily.

Abstract: An improvement in a magnetically focused image intensifier for increasing the usable range of magnification without degradation of image quality and while keeping to a minimum the power requirements of the focusing coils. The improvement comprises an arrangement of focusing coils which reverses the direction of the axial magnetic field distribution between the planes of the photocathode and the phosphor screen.

Abstract: An electron image intensifier includes an input image means having a curved photocathode surface for converting the optical image to an electron image. The electron image is imaged upon an output image means spaced from the input image means, with an annular accelerating anode positioned between for accelerating the electrons to produce the image intensification. An annular gateable electrode is disposed between the input image means and the accelerating anode. The gateable electrode is structured and positioned with an inwardly disposed end portion closely spaced from the perimeter edge of the photocathode surface, and extending along the radius of curvature of the photocathode surface. The structure substantially eliminates any distortion from the gating electrode.
