Abstract: HELICAL POT BROACHING MACHINE                 ABSTRACT OF THE DISCLOSURE           A helical pot broaching machine has a pot broach mounted to a base support structure.  Means for rotating a part while it is being pushed through the pot broach is mounted in-line with the pot broach and is connected to a driving piston mounted in-line with the rotating means.  The rotating means includes a helical nut housing mounted on the inlet of the pot broach and a threaded helical lead bar connected to the driving piston at one end through a swivel joint.  The lead bar has a collet attached to the other end which attaches to a part at the inlet of the pot broach.  As the piston vertically pushes the lead bar and attached part through the pot broach, the helical nut imparts rotary motion to the lead bar causing the part attached thereto to be also rotated as it passes through the pot broach.

Abstract: Abstract of the Disclosure A nozzle for atomizing fuel for combustion in a gas turbine engine.  During normal operation of the engine, the nozzle uses a portion of the air supplied to the combustion chamber by the engine compressor to atomize fuel flowing through the nozzle.  During start-up and low power operation of the engine when flow of engine air through the nozzle would otherwise be of insufficient velocity to cause good atomization of the fuel, additional air from a separate external source is introduced at high velocity into the nozzle in the manner of an ejector.  The additional air imparts high velocity to the engine air within the nozzle so that the air from both sources acts on the fuel at the nozzle discharge orifice at high velocity to effect good atomization and spray pattern of the fuel.  The nozzle is designed in such a manner as to cause no significant restric-tion of engine air flow through the nozzle under high power operation of the engine when the external air source is shut off.

Abstract: TITLE            APPARATUS AND METHOD FOR CONTROLLING            A MACHINE TOOL ALONG A CIRCULAR PATH                   ABSTRACT OF THE DISCLOSURE     In a control apparatus for a machine tool, an interpolator circuit for determining whether or not one of the axis motors should be inhibited on the next step to maintain the tool closer to the desired circular path. The interpolator utilizes information as to the distance from the initial position of the tool to the center of the arc defining the path of travel and which axis is to be inhibited initially to determine when to inhibit. The main logic circuit in the control apparatus begins a move of the number of steps equal to the distance to be moved along the axis which represents the shorter distance between the initial point and the center of the arc. The interpolator presets a counter with that number of steps subtracted from the number of steps equal to the distance to be moved along the other axis and increments that counter by one each time the selected motor is inhibited. At the octant point, the main logic circuit adds the counter total to the number of steps yet to be moved and continues the move while the counter total is converted to its negative and the counter is incremented by one for each time the other motor is inhibited. When the main logic circuit determines that the all of the steps have been moved, the counter total represents any correction to be made.

The multi-CPU and shared device access system comprises a plurality of sets of fan out paths (chan-nels), each set coupling a corresponding CPU as a source node; a plurality of input/output devices; and a plurality of control nodes (control units), each node including means for accessing the devices, for selectively intercepting the paths in order to com-plete a signal path connection to a single destination device.  Each control node further includes means (FIG. 2, element 25') for storing a table of indepen-dent path sets of CPU's and reserved devices and means (FIGS. 2-5) for managing the connection of CPU's to devices such that for any given selection, reservation or reconnection indication, the table is accessed by at least one control node for ascertaining whether the CPU is a member of a set of interfaces to which the device is reserved, if so, an available path is selected.  The control nodes thus allocate dynamically dissimilar path sets to devices and CPU's on an allegiance basis in order to increase the signal path connection probability by the devices to counterpart CPU's involved in the reservation, release, or recon-nection of the device and the CPU.

Abstract: FRICTION BRAKE Abstract of the Disclosure The present invention relates to a friction brake for a wheel which has a hub and is mounted for rotation about a central axis on an axle spindle.  The brake is of the type which includes a housing mounted on an inward portion of the spindle to encircle the hub for sealed engagement therewith to define a sealed annular chamber about the hub and the spindle.  A pair of disc units are coaxially aligned with the axis and with each other and are mounted within the chamber for movement along the axis.  A first disc unit of the pair is non-rotatable and mounted relative to the housing and a second disc unit of the pair is rotatable and mounted relative to the hub.  The first disc unit includes an outer disc and an inner disc with the remainder of the pair of disc units axially disposed therebetween. An annular brake acutating unit is mounted within the chamber in alignment with the pair of disc units for selective application of force to the inner disc as the outer disc makes contact with an interior wall of the housing.  At least three cylindrical devices are mounted to the housing to extend in an axial direction into the chamber at generally equally circumferentially spaced locations about the inner disc and the outer disc. Each of the devices has a biasing unit mounted thereon which make contact with the inner and the outer discs tending to increase the distance therebetween.  A disc retainer is mounted on the device to produce a predeter-mined frictional contact therebetween which is greater than a maximum force generated by the biasing units.  A unit is provided for engaging the inner disc with the disc retainer to allow limited axial movement of the inner disc without causing the disc retainer to move along the device. The actuating unit is capable of supplying sufficient force to the inner disc to overcome the predetermined frictional contact and the maximum force to position the disc retainer on the device to establish the location of the limited axial movement of the inner disc within the chamber.
