Abstract: ABSTRACT:        The invention relates to a rotary anode X-ray tube wherein the anode carries the high voltage during operation. In order to avoid flash-over between the rotor and the stator, a comparatively large air gap must be present between the two parts, thus only a small part of the energy supplied by the stator con-tributes to the acceleration of the rotor, resulting in a comparatively long acceleration time. The inven-tion enables substantially shorter acceleration times to be achieved in that an insulator is provided be-tween the rotor and the anode disc and in that the rotor is earthed. Only a minimum air gap is then re-quired between rotor and stator, because the breakdown strength is ensured by the insulating between anode and rotor. The anode is connected to the high voltage via a bearing. Moreover, the invention for the first time enables metal-ceramic rotary anode X-ray tubes to operate with a symmetrical high voltage.

Abstract: LARGE GEAR MANUFACTURE                 ABSTRACT OF THE DISCLOSURE      Large, coarse pitch gears are cut by a method utilizing incremental plunge-fed or incremental generation motions and a special circular face-mill type cutter having cutting blades spaced apart from each other at angular distances selected so that, when cutting a tooth slot, there can be intervals during the rotation of the cutting tool when no blade is engageable with the workpiece.  It is only intermittently, during these short, no-cutting intervals, that required plunge feed or generating motions are made.  At other times, i.e., when one or another of the cutting blades is engaged with the workpiece, the machine elements which are moved intermittently relative to each other to provide in-feed or generation, e.g., the oscillating cradle, rotating work-head, and sliding base, are all rigidly clamped to the machine base and to each other.  In the preferred embodiment of the machine for carrying out this method, clamping means including the sliding base as well as overhead tie-bar arrangements straddle the workpiece and cutter to achieve exceptional rigidity.

Abstract: METHOD OF MAKING DUCTILE IRON TREATING AGENTS     ABSTRACT OF THE DISCLOSURE         A method of making a more economical and reliable treating agent for use in late metal treatment when pouring metal castings.  The treating agent is defined as an essentially homogeneous solid cast block preferably con-taining alloying ingredients to nodulize or inoculate ferrous metal.  Each block is designed to present a generally uniform reaction surface to molten metal to be treated.  This is obtained by casting the block to a shape which snugly fits a prepared basin in the mold gating system over which the molten metal to be treated must flow, or to cast the block in an annular configuration through which the molten metal must flow.  The latter block has contoured inner surfaces which maintain a generally constant reactive surface as the block is consumed.  These blocks are preferably prepared by simul-taneously casting a large number in closely nested relation.          Each mold for said blocks receives molten material, out of which the agent is formed, from a common sprue; runners inter-connect the mold cavities and sprue, for example, in a simultated "Christmas tree" arrangement.  The gating system and mold cavity pattern, for casting the treating agent to a special shape are all comprised of a material that will vaporize upon contact by the molten treating agent, such as polystyrene.  The unitary "tree" structure of foam patterns and gating system is placed in a flask and surrounded by unbonded heat absorbing particles, such as sand or steel shot.  Rapid solidifaction is assured by the selection of heat absorbing particles and by the use of the vaporizable patterns to avoid noticeable segregation in the alloy blocks.     The blocks formed for the treating agent are characterized by increased homogeneity, absence of undesirable segregation, absence of internal oxidation, and absence or organic or refractory impurities   the blocks are less costly to make both as to capital requirements and operating expenses.

Abstract: MULTIPLE LINK CIRCUIT FOR A PORT MULTIPLEXER         ABSTRACT OF THE DISCLOSURE A multiple link circuit for coupling a plurality of telephone lines to the ports of a port multiplexer without requiring the splitting of C-leads is disclosed. The multiple link circuit includes an internal priority determining arrangement that eliminates the need for individual links to be scanned by an address scanner. Each link of the multiple link circuit is bridge connected to a C-lead and includes: a busy detector for detecting the busy status of the C-lead; and, a control circuit for controlling the coupling of a subscriber seized telephone line to the associated port. The priority determining arrangement prevents any lower priority control circuit from coupling a seized telephone line to the associated port if any higher priority line is simultaneously attempting to be so coupled. After signal processing (performed by a signal processor connected to the port) has ended, or some other release action occurs, a port generated release signal disconnects the seizing link from the port. While any link is connected to an associated port, make-busy ground circuits forming part of each link apply false busy status information to all of the C-leads connected to the other links of the multiple link circuit. The false busy status information prevents the linefinders associated with these other links from attempting to seize the busy port via those links. Termination of the conversation flowing through one link creates a WINK signal that causes the linefinder to release the associated line, if another link is connected to the associated port at the time the conversation is terminated.
