Title: Trip system for cam locking latch in a mounting structure for a loader attachment
Inventor: KACZMARCZYK EDWARD TED
IPC: E02F3/36
Filed: 1992-10-26
Granted: 1996-03-19
Abstract: A tractor-mounted loader has a quick coupler mounted to forward ends of the boom arms thereof.  The quick coupler includes a pair of attachment holders having their lower ends respectively pivotally connected to the pair of arms and selectively pivotable by a pair of attachment tilt cylinders. An attachment in the form of a bucket includes a pair of connecting brackets including pins engageable by recesses in the upper ends of the holders and receptacles for receiving coupler elements carried by the holders.  A pair of latch mechanisms are respectively carried by the pair of brackets and include spring-loaded latch pins which normally assume a latch position blocking passage of the coupler elements to or from the receptacles but which include ramp surfaces that cooperate with ramp surfaces of the coupler elements to cause the pins to be automatically moved from their latch positions to permit passage of the coupler elements into the receptacles during mounting of the attachment to the attachment holders. The latch pins may be manually moved to an unlatch position from which they are automatically released by being contacted by wedges carried by the holders when the latter are moved to a position disposing the coupler elements free of the receptacles during detachment of the attachment from the holders.  An alternate embodiment shows the coupler elements formed by the mounting brackets and the receptacles formed by the holders with the latch mechanisms being mounted to the holders.

Abstract: A hold and release mechanism for a fire door spring tension adjusting wheel  includes  a  finger which  is retractable when the adjusting wheel is rotated in a direction to increase the tension of the door spring but remains in engagement with a notch on the periphery of the adjusting wheel to prevent rotation of the adjusting wheel in the other direction as urged by the spring tension.  The finger is held within a bore in a block which is pivotably mounted to the plate supporting the adjusting wheel.  A toggle arrangement coupled to the holding chain and the block keeps the finger engaged in the  notch.    When  tension  on  the  holding  chain  is released,  the block is allowed to pivot so that the finger disengages from the adjusting wheel, which is then allowed to rotate under the urging of the fire door spring.  This arrangement permits an operator to adjust the spring tension without requiring that the tension applied by the holding chain be relieved.

Title: Cost metrics
Inventor: DENNIS STEPHEN V
IPC: B41J29/38
Filed: 1993-07-09
Granted: 2001-10-09
Abstract: A resource oriented host computer-printer system is disclosed in which the host computer and printer share information and data processing duties. A  system and method for analyzing the execution times for draw primitives allows the host computer to determine whether the printer will be able to render draw primitives in real-time. The inventive system sends a series of test instructions to the printer at the time the printers is installed on the host computer. A timer is used to time a predetermined period of time during which the draw primitives are sent to the printer for execution. Based on the number of draw primitives executed and the type of draw primitives executed, the system constructs a printer model. A log file is used to store the acquired cost metric data. In one embodiment of the invention, a clumping procedure is used to classify cost metric data. A series of cost tables stores the classified cost metric data. A map table provides a map to the cost table to speed up the process of cost metric data retrieval. At run time, a resource assembler calculates the cost of executing each draw primitive within a band to determine if the printer can render the draw primitive in real-time. If the band is too complex for the printer to render in real-time, the host computer will render the band and transmit the bit-map of that band to the printer. If too many bands on one page are complex, the host computer may render the entire page and transmit the bit-map for all bands on the page.

Title: Charging station for electric vehicles
Inventor: NOR JIRI K
IPC: B60L11/18
Filed: 1992-10-15
Granted: 2001-01-02
Abstract: A charging station for electric vehicles which have rechargeable batteries is provided. The charging station comprises a power section controlled by a fast acting power controller, a power connector and associated power cables for connecting to the vehicle, an interface with signal cables to carry status and/or control signals between the vehicle and the power controller, and a lockout which precludes delivery of power to the vehicle except when the power connector is in place. High charging currents are delivered to the battery of the vehicle as a consequence of signals at any instant in time to the power controller, so as to be able to turn delivery of the charging current on and off in less than a few milliseconds. The resistance free voltage of the vehicle battery is measured during intervals when the charging current is off, and the operation of the power controller is a function of the battery resistance free voltage at any instant in time. Operation may be manually controlled, whereby at least maximum voltage and current settings are preset by the operator; or operation may be completely automatic and under the control of a charge controller within the vehicle and associated with the battery. Thus, for each vehicle that is equipped with a charge controller, the operation of the charging station is battery specific, and may be quite different as to conditions of voltage and current being delivered to another electric vehicle which may be subsequently re-charged from the same charging station.
