Abstract: A stern drive is for propelling a marine vessel in water. The stern drive has an upper drive unit with a lower mounting surface; a lower gearcase coupled to the lower mounting surface and a trailing end surface that is angled relative to the lower mounting surface; and a propeller shaft extending forwardly from the lower gearcase and being configured to rotate a propeller for pulling the marine vessel in the water. The upper drive unit and the lower gearcase are configured such that when a forward side of the lower gearcase impacts an underwater obstruction, the lower gearcase is caused to pivot relative to the upper drive unit until the trailing end surface impacts the lower mounting surface, which thereby causes the lower gearcase to completely uncouple from the upper drive unit.

Abstract: A document viewing system is provided that includes a browser receiving one or more user requests to view a document being stored remotely. The browser issues a first request to a server for metadata associated with the document and based on the received metadata determines a selective number of tiles needed for viewing the document. The browser issues a second request to the server requesting the selective number of tiles for viewing the document. The selective number tiles are only those tiles available for viewing in a viewing area in the browser. The server sends the selective number of tiles in parallelized fashion to the browser. The browser receives the selective number of tiles from the server and displays the document to a user.

Abstract: A live data form system is provided that includes a client that executes a browser that receives one or more user requests to view or update a live data form being stored remotely. The live data form includes a plurality of data blocks having information that defines the live data form. The browser issues a first message with respect to viewing or updating the live data form. A server receives the first message and executes a first routine that analyzes the contents of the first message and formulates one or more query statements associated with a data block to be executed by one or more remote databases. When the one or more remote databases finish performing the one or more query statements, the server issues a second message to the browser that includes the results of the one or more query statements executed by the one or more remote databases via the client to either view or update the live data form.

Abstract: A system for real-time document indexing is provided that includes a browser that is executing on a client system. The browser includes functionalities allowing it to communicate with a remote computer system. A query interface executes within the framework of the browser. The query interface receives one or more query searches from an end-user and sends the one or more query searches to be processed by the remote computer system. The remote computer system sends to the query interface the results of the one or more query searches via the browser. The query interface assigns the results of the one or more query searches to a folder where the folder includes a unique identifier. The query interface indexes the results of the one or more query searches to the unique identifier of the folder.

Abstract: A mobile file uploading system is provided that includes a browser receiving a request to upload one or more selective files and issues a first message. A server receives the first message and determines whether the first message is requesting a download of a first software application, and if so, the server downloads to the user desktop the first software application where the browser executes the first software application. A file upload module is created when the browser completely executes the first software application. The file upload module manages uploading the one or more selective files from the user desktop to the server when a second message is sent by the browser. The file upload module initiates communications with the server and also issues one or more file system calls to a file system on the user desktop to retrieve the one or more selective files for uploading.

Abstract: Wall constructions and methods for constructing walls. In one embodiment, the wall is constructed from studs that each having a web that has at least one opening therein. The studs are oriented such that the openings in their webs are aligned to permit at least one spacer member to extend therethrough. The spacer members are formed with structure for engaging portions of the webs through which they extend. Retainers are provided on the webs of the studs for retaining the spacer members in position. In another embodiment at least two studs that have webs with openings therethrough are oriented such that the openings are aligned with each other. At least one spacer member is inserted through the aligned openings to engage a portion of each web through which they extend. The spacers are then brought into engagement with retainers on the webs of the studs.

Abstract: A battery protection circuit particularly for portable lamps employing rechargeable batteries is provided to prevent overdischarge of the batteries and includes a bulb drive transistor connecting a bulb across the battery with a switch interposed between one side of the battery and the bulb, a voltage sensing resistor connected to one side of the switch, a regenerative switch connected between the sensing resistor and the other side of the battery, and the regenerative switch including an output terminal connected by a base resistor to the base of the drive transistor. The regenerative switch includes a pair of transistors connected and cooperating such that when one of the transistors is turned on, the other is caused to be turned on, the transistors, further, maintaining each other on. As the dropout voltage of the battery is approached, the base drive of the drive transistor decreases which causes the bulb to become dim to thereby warn of the discharged state of the battery.

Abstract: Apparatus for mounting and demounting tires and methods of mounting and demounting tires. The apparatus may include a clamp for holding a wheel as well as a tire clamp and pushing device for gripping a tire and applying a moving force thereto. The tire clamp is mounted for movement toward and away from the wheel clamp and toward and away from a support for the wheel clamp. It is operated, during tire mounting, to nonaxially urge a tire having one part of one bead received in the drop center of a wheel away from the wheel to draw that part into the drop center while axially moving the tire at a remote location toward the wheel so that the beads at the remote location are disposed between the flanges of the wheel.

Abstract: A power failure light for monitoring a power line and for illumination upon the interruption of power therefrom includes a light bulb, a rechargeable battery, a power supply providing charging current for the battery, a pair of diodes connecting the battery across the power supply, a pair of cascaded transistors connecting the bulb across the battery with the base-emitter junctions of the transistors connected across the diodes to thereby sense the condition of the power line. The base-emitter junctions are reversed biased by the pulsating voltage across the diodes, and a timing network, including a resistor across the power supply and a capacitor across the diodes, maintains the reverse biased condition of the junctions between the voltage pulses.

Abstract: In the prevention of atmospheric pollution by sulfur dioxide emissions from acid absorbers in contact process sulfuric acid plants in which the unconverted SO.sub.2 is accumulated by adsorption in a zeolite adsorbent bed and desorbed back into the acid production system, it is found that ambient moist air, after partial dehydration in an acid scrubber is suitably used both to cool down and hot purge desorb the zeolite beds. In addition the pure water derived from the ambient air is advantageously used in the acid-making system.
