Abstract: ABSTRACT OF THE DISCLOSURE    A leader tape staking rod and related method of assembly are provided.  The staking rod includes an injection molded, elongated member having two opposing, substantially flat sides, two opposing, subsantially curved sides, a first end and a second end, and a square-shaped opening formed through the elongated member from the first end to the second end.          The method uses a tool having a corresponding square-shaped tip for engaging and transporting the staking rod to the vicinity of the leader block which receives the leader tape in a substantially cylindrical opening.  The staking rod is then inserted into the opening formed in the leader block in a direction perpendicular to the longitudinal axis of the opening with its two opposing, substantially flat sides adjacent the mouth of the opening.  The staking rod is then rotated about the longitudinal axis of the opening formed in the leader block by the tool to a point where its two opposing, substantially curved sides create an interference fit with the walls of the opening formed in the leader block, permanently trapping the leader tape in position.  The tool is then withdrawn in a direction colinear with the longitudinal axis of the opening.

IPC: G06F13/38
Filed: 1987-02-05
Granted: 1991-09-10
Abstract: Abstract of the Disclosure The capacity of programmable controllers with a processor module and I/O modules connected in a single equipment rack is expanded by connecting an I/O expansion module in one of the positions normally occupied by a conventional I/O module.          The I/O expansion module communicates with the processor module through the rack backplane and also communicates with other racks of I/O modules and with node I/O modules through a serial data channel.  Data for I/O modules on the serial data channel are stored in a bulk storage area in the proces-sor module to expand the effective size of an image table of I/O status data that is maintained by the processor module.          The processor module is programmed to operate with a back-plane controller in the I/O expansion module to transfer data in or out of the bulk storage area.  Besides the back-plane controller, the I/O expansion module includes a serial channel controller, a common memory and arbitration circuity which allows the controllers to alternate access to the common memory and to exchange data.  The serial channel controller controls multiplexing and demultiplexing of I/O status data with the I/O modules through the serial data channel.

Abstract: FLUIDIC OSCILLATOR ABSTRACT OF THE DISCLOSURE     A fluidic oscillator is relatively short in length (under about 2.5 W where "W" is the width of the power nozzle) and has leaky splitter located proximate the center of the outlet flare so as to divide the outlet into essentially two alternating slug flows.  The floor and/or ceiling of the oscillator diverge between about six degrees and ten degrees to allow the jet streams to expand and thereby avoid creating a back pressure to control ports.  When used as a windshield defrost/defor nozzle, vanes forming part of the leaky splitter are laterally shifted so that the largest opening is on the driver side and the smaller opening is on the passenger side so as to direct more defrost energy towards the driver's side.
