Abstract: A CRUISE CONTROL SYSTEM FOR A VEHICLE                  ABSTRACT OF THE DISCLOSURE          A cruise control system for a vehicle having an internal combustion engine provided with a throttle valve operated by a diaphragm actuator irrespective of a depression of an accelerator pedal by an operator of the vehicle.  The system is provided with a system for controlling a vehicle speed in a so-called "dead zone" where hunting usually occurs if a normal feedback control is executed.  A time-interval integrating unit is provided for integrating the deviation of the actual speed with respect to the target speed with a time interval as well as a weight factor, so that the integrated value corresponds to the change in the deviation in the dead zone.  The integrated value is compared with a predetermined value corresponding to a change in the vehicle speed which is obtainable when the least significant bit in the control signal output to the actuator is changed.  When the integrated value becomes equal to or higher than the predetermined value, the least significant bit is incremented or decremented, and thus speed control in the "dead zone" becomes possible.

Title: Terminal
Inventor: MOONEY ROBERT C
IPC: G09G5/14
Filed: 1987-07-28
Granted: 1992-02-11
Abstract: ABSTRACT          In a dumb terminal to which an auxiliary device may be attached, improvements in display definition, in the transfer of data between a host computer and the terminal or an auxiliary device, and in character generation memory.  In the area of display definition, pages may be mapped onto the terminal's display memory and viewports may be mapped onto pages.  Page and viewport definition are independent of each other and settable modes permit a viewport to follow the active position.  In the area of transfer of data, the source of data for the host computer and the destination of data from the host computer may be specified independently.  Improvements in flow control ensure that the host computer can always change the destination of data and gain control of the terminal.  Improvements in access control ensure that neither the terminal nor the auxiliary device can monopolize transfer between it and the host.  Moreover, transfer can proceed transparently even when non-ASCII 8-bit codes or a 7-bit host-terminal link are involved.          Finally, a protocol permits one portion of character generation memory to be copied to another portion thereof.

Granted: 1992-06-30
Abstract: STRAIN GAGE BEAM HAVING INTEGRAL OVERLOAD PROTECTION          ABSTRACT OF THE INVENTION         A sensitive deflector beam having an integral deflectable element utilizes an immobilization pin and a limit pin to prevent damage to the deflectable element during fabrication and use.  The immobilization pin is inserted through the beam and to the deflectable element to hold the element rigidly in place during fabrication.  Thus, relatively rigorous operations such as polishing and circuit deposition may be accomplished without damage to the element.  By inserting a limit pin, which allows a preselected degree of motion in the deflectable element, the beam may be operated without overstressing.

Title: Louver holder for vertical venetian blinds
Inventor: EVANS J RICHARD
IPC: E06B9/36
Filed: 1987-11-24
Granted: 1991-08-27
Abstract: ABSTRACT OF THE DISCLOSURE          In venetian blinds a combination of a louver clip and a louver sleeve for supporting a louver.  The louver sleeve has a cylindrical opening with an obstrusion on the lower part of its periphery having a cross-section in the form of a segment.  The louver clip comprises a shank and a stem on top of the shank.  The stem is adapted to be intro-duced in the sleeve.  The stem has a longitudinal axial flat adapted to match the flat side of the obstrusion.  The stem is provided with an aperture in its upper portion extending through the axial flat.  An anchor tab extends from the top of the stem and projects downwardly in the aperture and angularly so as to project outside the contour of the stem. When the stem is introduced in the sleeve, the tab catches the top surface of the obstrusion which acts as a support for the stem.  The advantage of this combination resides in the fact that if the shank breaks away from the stem, another clip is used to push the broken stem out of the sleeve.  The anchor tab of this new clip catches the top surface of the obstrusion and fits as the original clip.

Abstract: A packet switching techniques, protocols, networks, and equipment for use on a local area or wide area scale.  Packets include a fixed-length data field and memory offset field are employed so that packeting, block data transfer to contiguous memory and depacketing are effected at the destination by hardware-mediated processes with minimal processor involvement.  Multiple sessions are readily handled by assigning addresses to multiple memory buffers at the destination.  Each packet carrying computer data provides three levels of addressing for its data segment corresponding to the destination node or device, the memory buffer and the memory location. The equipment includes loopbased, collision-free packet switches in which packets are modified and re-circulated when a destination is busy.  Loop latency is minimized and data transfer rates maximize by the use of fully-buffering parallel forms of the switch. A method for handling broadcast is also disclosed, together with a technique for preempting low priority packets and exploiting short-cuts on a loop.  These improvements allow application of the technique to a high-speed voice/data packet-switching in large wide area networks as well as in small local area networks. Thus, an extensive, powerful and extremely fast integrated communications subnet can be build in hardware with little processor intervention.

Abstract: ABSTRACT OF THE INVENTION An electronic orchard tree measuring system based on ultrasonic range transducers may be used to determine the amount and vertical distribution of sensed load centroids in vertical sectors of orchard trees.  The ultrasonic transducers may be operated independently of any processor or memory which receives their distance data outputs.  Displacement sensing of the apparatus relative a row of target trees may instead be used to select ultrasonic distance data at predetermined incremental distances of travel relative the trees being sensed.  Thus, the most recent value of sensed data is always available as input to the processor or memory, without requiring any timing circuitry between such sensing and control circuits.          The detection data may be stored in memory for subsequent processing to create a map of foliar volumes of the sensed target trees.  Alternatively, the spatial characteristics of the sensed amount and vertical distribution of load centroids for a given vertical segment of target trees may be further compared spatially with determined application patterns of controllable spray nozzles to configure subsequent activation of such nozzles for optimal material application to the given vertical segment of the sensed target trees.

Abstract: 1909.016   DOWNWARD) GAS-METAL-ARC WELDING PROCESS     ABSTRACT OF DISCLOSURE     A gas-metal-arc welding process, utilizing a consumable, axially advanced, wire electrode and a four-gas shielding mixture, forms a weld bead along a vertically downwardly direction. As the bead is formed, the electrode is moved vertically downwardly in alignment with the central axis of the bead, with the tip of the electrode gapped from the weld material deposit which forms the bead. A relatively high electrical voltage and current density is applied to the electrode to produce a stable, conically-shaped hot plasma field. The field is concentric with the axis of the electrode and extends across the gap. The plasma field is positioned to transversely overlay, and to be substantially coextensive with, the full width Or the bead. Molten metal globules transfer by free flight along the axis of the field, from the electrode tip across the gap to the weld deposit to laterally spread out and adhere to the deposit to form the bead.     ewp/1909.016/bjcX
