Abstract: The present invention relates to a method and apparatus for preventing the use of data transmitted by a computer to a web site by a program operating on the computer. Initially, a first association between a set of labels and a first set of codes is created. The set of labels contains information to be displayed on the computer, while each code in the first set of codes is associated with a particular label. An encryption key is then linked with the first association. The set of labels, the first set of codes, and the first encryption key is then sent to the computer. Some time later, codes from the first set of codes and the first encryption key are received back from the computer. The codes returned from the computer are then matched to labels from the set of labels using the first encryption key. Afterwards, subsequent associations between the set of labels and other sets of codes are created. These associations are different than the association between the set of labels and the first set of codes.

Abstract: A system and method for monitoring passengers during boarding or disembarking of a passenger carrier is provided. This includes providing a passenger monitoring system at a gateway area for boarding or disembarking of a passenger carrier for a designated carrier event. The passenger monitoring system may include a passenger data collecting device, an instruction input device, a video monitor display device and a data processor that is in communication with a remotely located central database containing stored carrier and passenger data for the carrier event. Passenger boarding or disembarking data from at least one passenger is collected during boarding or disembarking operations at the gateway area with the passenger monitoring system. The stored carrier and passenger data is updated with the collected data. The stored carrier and passenger data is displayed on the display device of the passenger monitoring system upon inquiry instruction input into the instruction input device.

Abstract: A sealed edge joint can be formed between two metal panels such as an outer vehicle door panel and an inner door panel, by using a flowable sealant bead between the facing surfaces of the two panels, and a thin film of uncured paint-like resin between a flange on the outer panel and the exposed surface of the inner panel. The paint film is cured to a solid impervious condition by a baking operation performed on the completed door panel assembly.

Abstract: A scroll compressor includes a fixed scroll member and an orbiting scroll. The orbiting scroll member is operatively connected to a motor to be driven in an orbiting motion by the motor. The scroll members each include a plate having an inboard surface and an outboard surface. A spiral involute or wrap is formed on the inboard surface of each scroll member plate. The involutes mate to define suction zones at outer ends of the involutes and fluid pockets. The fixed scroll member defines a fluid outlet at the center of the involutes and two inlets positioned proximate the suction zones. At least two idler crank assemblies are provided to maintain the phase relationship and running clearance between the scroll members. The idler crank assemblies each include two operatively connected cranks, one being in the fixed scroll and one being in the orbiting scroll. The fixed scroll crank is externally accessible so that its rotational motion may be harnessed to drive a fan or another compressor stage, for example.

Abstract: The present invention is a digital and analog system for generating an energy log for instant recall and display. The system is permanently programmed in read-only memory with the task of scanning sensor inputs, performing consumption calculations, updating the non-volatile memory, responding to external commands, and monitoring peripheral performance. The stored information is available for real-time query of individual sensor data or as a composite hard copy report on a month-to-date or month-end basis. The apparatus accepts inputs from both analog and digital sensors whose outputs produce information related to data such as current consumption, water consumption, or fuel consumption and provides an optional interface for the control of these functions based on pre-programmed upper/lower limits.

Abstract: A shipping device for a heater unit assembly (23), the heater unit assembly (23) including a cylindrical wall (25) and a top plate (31) secured to the cylindrical wall (25) and having a flange portion which projects radially beyond the outer surface of the cylindrical wall (25), and the shipping device including: a cylindrical container (3) having a closed bottom (13); a support member (47) secured to the container (3) and having an inwardly directed flange for supporting the flange portion of the top plate (31); a supplemental supporting system (1) for positioning the heater unit assembly (23) in the container (3) at a spaced relation from the inner surface and bottom wall (13) of the container (3); a cover (15) for closing the top of the container (3); and a container supporting structure (5,7,8) supporting the container (3) in a manner to permit the container (3) to be moved, relative to the supporting structure (5,7,8 ), between a vertical position for loading and unloading the assembly (23) and a horizon

Abstract: Two sets of heater support members angularly distributed around a central vertical member are radially extendable individually or in groups to position heater elements within a preset distance of the cylindrical walls of any one of a series of pressure vessels having a range of diameters. A convex bottom heater support member is provided for each diameter vessel and is axially telescoped into the central vertical member so that an additional set of heater support members can be installed between the first mentioned two sets of heater support members and the bottom heater support member to accommodate for varying depths of the vessels in the series. Thermocouples are extended from the annealing device by actuators which use a spring or pneumatic pressure to press the thermocouple against the vessel wall with a preset constant force for accurate temperature measurements.

Abstract: An apparatus for actuating a tube guide expander device inserted in a tube end and extracting it therefrom subsequent to tube expansion induced by guide-expander actuation. The apparatus includes inner and outer sleeve structures which are independently axially displaceable relative to the tube and guide-expander. The outer sleeve structure is engageable with a first compression structure of the device to secure it and its engaged tube in place during relative axial displacement of a second compression structure of the device.Selectively coupling the inner sleeve structure to the device's second compression structure and axial displacement of both axially compresses a radial expansion element situated between the compression structures and expands the enclosing tube.

Abstract: A method for inserting a tube through a tubesheet aperture and expanding it into contact with the aperture's wall. A tube guide-expander device is assembled in an open end of a tube with a portion of the device protruding from the tube. The guide-expander includes a distally protruding tip portion tapered to diverge in a direction toward the tube so as to facilitate insertion of the guide-expander and engaged tube through apertures in spatially separated tube supports and tubesheet. The guide-expander and tube engaged therewith are axially displaced relative to the tubesheet until the desired relative configuration is obtained. Expansion of the tube results from expanding the assembled tube guide-expander and driving the housing tube in the radial direction against the tubesheet aperture's wall. Such guide-expander expansion obtains from relatively axially displacing two structural components and compressing an interposed, radially expansible structure.
