Granted: 1984-08-14
Abstract: Abstract of the Disclosure A data bus system includes a plurality of interconnected active terminals, i.e., terminals which receive data from one terminal and retransmit it or transmit new data to another terminal. The data is in serial digital form and is transmitted within a continuous series of time frames of predetermined length with each time frame being initiated by a control word transmitted by one of the terminals designated the controller terminal.  Each terminal includes a counter which counts the bits between control words, and each control word includes an identification of the controller terminal so that each terminal can synchronize its counter with the counter at the controller terminal in accordance with the propagation time of data from the controller terminal.  Logic circuitry is provided at each terminal so that one of a plurality of terminals can assume the function of the controller terminal should the presently designated controller terminal fail to generate control words to define the time frames.  Within each time frame various of the terminals initiate data at appropriate times in accordance with the count on the counter of the initiating terminal, and the transmitted data is coded with the identification of the receiving terminal or terminals which are to direct the data to users tied in to those terminals.

Abstract: ABSTRACT OF THE DISCLOSURE A fishing tip-up utilizes a rocker arm which is pivotally mounted to a body member for oscillation about a horizontal axis to effect an up and down jigging movement of a hook and bait on a line associated with the arm so as to attract fish.  The oscillation of the arm is accomplished through the use of a wind vane attached to the arm which serves to cause a movement of the arm in response to air movement coming into contact with the vane.  An adjustable spring is operably attached to the pivotal arm so as to assist the wind vane in creating the up and down movement, and a tip-up flag assembly is provided to signal a remotely-located fisherman that a fish has taken the bait.  The fishing line is wound on a spool journaled on the arm with the spool including an adjustable friction brake structure and the line extends through an aperture in the vane.  The body member of the fishing tip-up is pivotally attached to a base member to enable folding for storage with the base member having extended ends so that excess fishing line may be wrapped about the base member when the tip-up is folded into a stored condition.

Abstract: ABSTRACT OF THE DISCLOSURE          A sealing element for a snap-on fitment has spaced apart inner and outer skirts engageable with opposite sides of the container neck, an annular wall interconnecting the skirts and an extension from the annular wall forming a fitment engaging portion.  An annular snap bead extends from the connect-ing annular wall to facilitate snap engagement with the fitment, and the engaging portion has an inner sealing surface and a seal bead adjacent its outer end.  The connecting wall has an annular relieved section opening into the space between the skirts so that any distortions imposed upon the snap bead and upon the sealing surface as occasioned by any dimensional and/or shape irregularities in the container neck are reduced by the relief provided between inner and outer engagements with the container neck.  This results in an isolation of any distortions of the skirts relative to one another, an isolation of any outer skirt distortion relative to the snap bead, an isolation of any inner skirt distortion relative to the sealing surface, and the maintenance of dimensional stability between the snap bead  and the sealing surface.

Abstract: ABSTRACT OF THE INVENTION         A thermal transfer printing head for printing gray scale television frame images is driven by pulse width modulated signals derived without the use of comparators by employing a read only memory in which pulse width modulation data has been stored.  The read only memory is addressed by the data signals and a reference gray scale counter to produce pulsed output signals fed to a random access memory.          The random access memory is then read out by addressing it with addresses corresponding to gray scale reference signals and cyclical addresses produced by an address counter.  The random access memory output signals, representing the pulse width modulated image data, is converted to parallel signals fed to a latch and driver circuit for energizing the individual heat elements of the thermal printing head.

Abstract: ABSTRACT      A device for feeding successive sheets without overlapping the sheets includes a loading chute having a recess formed therein at the exit end for guiding individual sheets, a pivotally mounted retractable gate at the exit end of the chute which when in the closed position extends into the chute recess, means to retract the gate so that a sheet may be fed from the chute including means to release the gate from the retracted position after the leading edge of the sheet has passed the closed position of the gate and before the trailing edge of the sheet has passed the closed position of the gate. The release permits the gate to float against the sheet in the recessed portion of the chute so that when the trailing edge of the sheet being fed passes under the gate, the gate drops of its own weight into the recess thereby blocking passage of the next sheet. In a preferred embodiment the loading chute is inclined to the horizontal.

Abstract: Synchronous Clock Stopper For Microprocessor Abstract A synchronous clock stopper circuit for inhibiting clock pulses to a microprocessor in response to a stop request signal, and for reinstating the clock pulses in response to a start request signal thereby to conserve power consumption of the micro-processor when used in an environment of limited power.  The stopping and starting of the microprocessor is synchronized, by a phase tracker, with the occurrences of a predetermined phase in the instruction cycle of the microprocessor in which the I/O data and address lines of the microprocessor are of high impedance so that a shared memory connected to the I/O lines may be accessed by other peripheral devices.  The starting and stopping occur when the microprocessor initiates and completes, respectively, an instruction, as well as before and after transferring data with a memory.          Also, the phase tracker transmits phase information signals over a bus to other peripheral devices which signals identify the current operational phase of the microprocessor.

Abstract: METHOD AND APPARATUS FOR ANCHORING RETAINING   WALLS AND THE LIKE, AND INSTALLATION THEREFOR     Abstract of the Disclosure A recoverable earth-retaining wall anchoring device and method is disclosed which allows the erection of a retaining wall in a quick, inexpensive manner and permits proof-load testing of the anchor during or immediately after installation, resulting in significant time and cost savings.  The device includes a screw anchor having a central, elongated shaft with one or more outwardly extending helical blades affixed thereto, and an earth-penetrating lead point at one end.          An adapter is attached to the anchor shaft and includes an opposed, threaded bore which receives an elongated threaded rod; a polygonal in cross-section engagement area is also provided between the opposed ends of the adapter.  A wrench, having one or more releasably interconnected, tubular, polygonally-shaped shank sections is telescoped over the rod and operably and drivingly engages the adapter engagement area such that axial rotation of the wrench effects corresponding rotation of the anchor for installation and removal purposes.  Multiple wrench shank sections are telescopically interfitted and releasably joined together by means of a spring biased locking dog inserted in aligned shank apertures.  This dog is substantially flush mounted on the outer wrench section by means of an elongated, flat leaf spring which can be alternately positioned for maintaining the dog in a locking or a recessed position.  The wrench may be easily removed from the soil because of the substantially flush configuration of the spring dog locking mechanism.  The installation torque may be used to infer anchor load-bearing capacity and additionally, the device may be accurately proof-load tested and used immediately after installation, thereby eliminating costly construction delays.  After the anchor is installed, the elongated rod is secured to the retaining wall thereby restraining the adjacent earth mass from lateral shifting.
