Abstract: A method and apparatus for monitoring and maintenance of unattended robot liquid storage and dispensing sites, including a site controller and site monitor. The site monitor continuously appends text strings received from the site controller to HTML text log files and HTLM text report files and simultaneously compares the stored text strings representing site events to be monitored with evaluation messages. Each evaluation message is linked to an alert code, which in response to an evaluation message text string match initiates a particular set of responses, including sending notice of site failures and other remote site information to a home office via fax, pager and/or email. The site monitor also collects the information gathered from the site controller, the tank monitor, alarm system and any other site devices and stores the information in a one or more HTML text files, which information then takes the form of a web page with hypertext links to images related to the stored information.

Abstract: A system and method is provided for optimizing the data transfer performance between a host computer and a peripheral data storage device adapted to transfer data in accordance with an internal set of configurable, performance setting parameters which determine the device's data transfer performance. A device driver program evaluates the I/O request stream of application programs hosted by the computer, and identifies any patterns evident in the I/O request stream. Identified I/O request patterns are matched to a corresponding set of data storage device performance setting parameters, i.e., mode parameter pages, which have been predetermined as able to optimize the data transfer performance of a data storage device for the identified I/O pattern. The new performance setting parameters are written to the data storage device which is operated in accordance therewith, thus tuning the data storage device for an application's I/O request pattern.

Abstract: Improved, lightweight multi-passenger aircraft seating unit utilizes an elongated, generally S-shaped, composite panel to provide the sole support for the seat cushions, the seat back and seat back tray table, the seat belt anchors and the armrests. Front legs and rear legs made of thin sheet metal can be attached directly to the panel by bolts passing through the panel. A downwardly projecting front portion of the panel and an upwardly projecting rear portion, in cooperation with channel-shaped members bonded to the panel's peripheral edges, enhance the rigidity of the panel. The unit provides cantilever support without the necessity for the front and rear tubular stretcher members and the fore and aft support members used in conventional seats. The composite panel has a honeycomb core and its top and bottom skin surfaces are formed of continuous layers of resin-impregnated fibrous material such as graphite fibers, with additional swatches of such material overlying and integrally bonded into the skin.

Abstract: An improved track fitting for anchoring an aircraft seat to a seat track has a threaded "anti-rattle" fastener for forcing a flanged top portion of a movement restricting shear pin against the top of the seat track to prevent rattle and wear due to aircraft vibrations. A pivoted lever which also functions as a cover for the fitting is mounted on the body of the fitting for lifting the shear pin against the force of a shear pin spring which normally urges the pin into locking engagement with one of the slots in a seat track. To prevent tampering by a passenger, the lever is rendered inoperable when the anti-rattle fastener is actuated. A leaf spring carried by the lever engages the body and prevents the lever from rattling due to vibration. The lever can lock the shear pin in its upper disengaged position as the seat fitting is lowered into the seat track and can then be released so that the shear pin will drop into one of the slots in the seat track automatically as the fitting is moved fore or aft.

Abstract: Improved framing system for a multi-passenger seat incorporates a generally inverted L-shaped rear leg whose shorter leg portion is joined to the rear stretcher tube at its free end and to a compression member at its point of intersection with its longer leg portion. The compression member and short leg portion form one side of a triangle which includes the front leg and a support member connecting the front and rear stretcher tubes. The longer leg portion forms one leg of a triangle which includes the compression member and a seat track covering member. The design provides greatly improved passenger leg room for close pitch seating arrangements.

Abstract: A unit for use in a diving bell to heat and remove carbon dioxide from the breathing gas in the bell. A blower circulates the atmosphere in the diving bell through a heat exchanger, which is heated by hot water from an installation on the surface. Part of the air is vented back into the bell atmosphere and part is passed through a scrubbing canister containing material which removes carbon dioxide from the gas. The unit is very compact and the scrubbing canister is readily replaceable for servicing. In the hot water system, provision is made for controlling the flow and for delivering hot water to divers having heated suits.

Abstract: A diver's gas heater, for use with a hot water heated suit, to heat the diver's breathing gas for added comfort in cold water. Hot water from a surface installed source is pumped through a hose to the diver's suit and the heater is installed directly in the hot water supply hose. The hot water passes through a tubular heat exchanger and the breathing gas flows through an annulus around the water conducting tube. A portion of the hot water is tapped off to maintain heating around the short length of breathing gas hose between the heat exchanger and the diver's helmet.
