Abstract: A dictionary based technique for accessing elements of a data structure used by an object oriented program involves creating a dictionary for the elements which compose the data structure including location information for each element. Responsive to a request for a particular data structure element, the dictionary is interrogated to return a pointer to a desired instance of a particular data structure element to the requesting process. The dictionary finds particular application in dynamic and complicated Internet programs written in JavaScript, where a typical data structure is a response/request based database structure which parallels a request and a response in an Internet protocol. Object constructors which utilized to initialize properties on an object are also generated from the dictionary. Once a request is recieved to generate object constructor code for an object in the object oriented program, rule data for naming properties of the object are retrieved from a rule database.

Abstract: Disclosed is an automated data storage library in which a library accessor, arranged for accessing data recording media stored in storage bins, may also exchange electronic components of the library. The media are provided with access engagement surfaces for engagement by the library accessor(s). A plurality of removable mounts, having access engagement surfaces matching the data recording media access engagement surfaces, are provided for individually mounting electronic components, such as data storage drives and communication jumpers. Component slots are provided in the library for individually supporting the removable mounts, and mating low insertion force connectors are provided respectively on the removable mounts and ones of the component slots for removably connecting the electronic components to the library.

Abstract: A storage and retrieval library has a column of storage cells including at least some side-by-side storage cells. A media accessor with a picker gripper for accessing media in one side of the side-by-side cells is rotatable about a pivot to an opposed position for accessing media in the other side of the side-by-side cells. For multi-sized media, a column may have storage cells extending the full width of the column for holding a large sized media, and a second type of smaller cells arranged side-by-side, each for holding a small sized media. A media picker has a first gripper for accessing large sized media from the full width cells, and a second gripper for accessing small sized media from one side of the side-by-side cells. The media picker is rotatable about a pivot to an opposed position for the second gripper for accessing small sized media from the other side of the side-by-side cells.

Abstract: Disclosed is an automated data storage library for storage and retrieval and selective export and import of portable data storage media stored in storage cells of portable magazines. Each portable magazine has a detent, and has registration surfaces, such as a sleeve at each of two corners. A columnar elevator supports a columnar stack of the portable magazines, and has an opening at its top level external to the library, and pushes the stack toward the top level. Fixed registration shafts in the library mate with the magazine sleeves to prevent lateral movement while allowing columnar movement of the magazines. The media may be accessed by a picker at the storage cells of the magazines at all levels in the stack internal to the library. A releasable latch engages the detent of the magazine at the penultimate level of the stack (e.g., the top position within the library), holding the stack against the upward pushing of the elevator, and external latches each engage a magazine in the stack at the top level.

Abstract: A computer system for providing application program developers a technique for building a plurality of panel displays from a single, comprehensive panel definition source file. The system includes routines for creating panel definition information, acquiring a copy of previously created panel information and displaying panels dynamically created at run time using previously stored panel definition information. The system also allows the specification of modifications to panel displays at run time as well as an option for look ahead processing of previously defined and newly specified panels at run time.

Abstract: The present invention provides a retainer system of an automated storage and retrieval system, or library, which prevents information storage elements, or cartridges, from escaping from their respective storage cells when the entire library is transported from one location to another. The retainer system comprises a retractable cable, a null, or dummy, cartridge, and an array of storage cells. One end of the retractable cable is attached to the null cartridge and the other end of the cable is affixed to one end of the array of storage cells. Initially, the null cartridge is positioned in a storage cell located adjacent to the end of the storage array where the cable is affixed. When all the information storage elements are placed inside their respective storage cells within the array, the null cartridge is moved from its original position to a storage cell at the opposite end of the storage array.

Abstract: A transition connector in which all contact elements are identical has opposing teminals connected by a foldable strap to permit keeping all the terminals of each set at the same extended length. The contact elements are anchored to the insulative carrier for security during assembly.

Abstract: A portable vehicle engine handling hydraulic hoist including a wheeled base for mounting a vertically and swingable base boom with a tiltable and longitudinally movable horizontal boom pivoted to the upper end thereof. A nose pivoted to the outer end of the horizontal boom includes a shaft for carrying an engine supporting sling having spaced arms for bolting connection to the engine. A self-contained electric motor, hydraulic pump and oil reservoir are arranged on the base and connected by hydraulic lines to a control panel with control selectors adapted to be handled by the operator for selectively hydraulically actuating hydraulic cylinders in and connected to the booms and the horizontal boom nose and engine sling mounting shaft whereby an engine requiring repair may be readily disconnected from its motor mounts and transmission and so manipulated with precision and removed from a vehicle within the close confines of a stall in a repair shop and replaced when repaired or another engine installed.

Abstract: In a material transfer system, a substantially airtight hopper is rotatably supported at the top of an upright column which is in turn supported by a base. The hopper may be divided into a plurality of compartment sections, and inlet and outlet ports are provided for each hopper compartment. A vacuum pump is connected to the interior of the hopper through the column. A hose is adapted for connection to one of the inlet ports to direct material into the hopper, and sealing apparatus is provided for closing the remainder of the inlet ports. Each discharge port is provided with a chute for receiving and transferring material under the action of gravity. Drain apparatus is provided for receiving liquid from each discharge port. Each discharge port is further provided with structure for sealing the discharge port in response to the presence of vacuum within the hopper.
