Abstract: A scroll pump facilitates the installation of a new tip seal between an axial end of the scroll blade of one of inner stationary and orbiting plate scrolls of the pump and the plate of the other of the inner stationary plate and orbiting plate scrolls. To this end, the orbiting plate scroll has a central portion and an outer peripheral portion extending around and seated on the central portion. The outer peripheral portion of the orbiting plate scroll is keyed to and/or fastened to the central portion such that the outer peripheral portion is not rotatable relative to the central portion and yet is axially removable from the central portion. The tip seal can be readily accessed and replaced by removing the outer peripheral portion of the orbiting scroll plate from the central portion.

Abstract: A scroll pump has a tip seal between an axial end of the scroll blade of one of stationary and orbiting plate scrolls of the pump and the plate of the other of the stationary plate and orbiting plate scrolls. The scroll pump may have a ballast gas supply system and use the operation of the ballast gas supply system to assess the condition of the tip seal. Alternatively, the scroll pump may have two pressure sensors that sense pressure at two locations spaced along a compression mechanism of the pump to assess the condition of the tip seal.

Abstract: Parts of a pump head of a scroll pump facilitate an assembly process in which the stationary and orbiting scroll blades of the pump are angularly aligned or synchronized with one another. A metallic bellows of the pump head provides a primary means of synchronizing the stationary and orbiting scroll blades. The assembly process may be carried out using a fixture configured to be mountable to an assemblage including the bellows and the orbiting plate scroll. The fixture has a reference feature, and the orbiting plate scroll or the frame has another reference feature that can be aligned with the reference feature of the fixture, in the circumferential direction of the bellows, during the course of the assembly process.

Abstract: A modular pump platform includes a pump head module, a pump motor module, an electronics module and a separable tray. The pump motor module includes a pump motor having a rotary output removably coupled to a crank shaft of the pump head, the pump motor being one of multiple types of pump motors, and the pump motor module being detachably connected to the pump head module. The electronics module includes an electronic control circuit configured control operation of the pump motor, the electronic control circuit being one of multiple types of electronic control circuits corresponding to the types of pump motors. Each of the pump head module, the pump motor module and the electronics module is detachably connected to the separable tray. At least the pump motor module is interchangeable with another pump motor module comprising a pump motor of another type.

Abstract: A scroll pump isolates vibrations of a pump head/motor assembly of the pump from the exterior of the pump and thus, suppresses the production of airborne noise. The pump includes a sound-muffling enclosure surrounding the pump head/motor assembly, feet supporting the enclosure, and elastic vibration isolators. The pump head/motor assembly is fixed to the tops of the vibration isolators, and the sound-muffling enclosure is fixed to the vibration isolators at the bottoms of the isolators. The scroll pump also has a locking system by which motion of the pump head/motor assembly relative to the sound-muffling enclosure can be limited or prevented, and by which the sound-muffling enclosure can be hard-mounted to a support surface independently of the feet.

Abstract: Scroll pumping apparatus includes a first scroll element and a second scroll element; a drive mechanism operatively coupled to the second scroll element for producing orbiting motion of the second scroll element relative to the first scroll element, the drive mechanism having an axis of rotation; and an isolation element to isolate a first volume and a second volume in the scroll pumping apparatus. The isolation element includes a first resilient annular member coupled, directly or indirectly, to the first scroll element, a second resilient annular member coupled, directly or indirectly, to the second scroll element, and a tubular member coupled between the first and second annular members.

Abstract: Aspects for maintaining and providing a calibrated color environment for display devices of a computer system. In an aspect of an exemplary method, the method includes determining relevant state data. The method further includes saving the relevant state data as calibration information for the calibrated color environment. The relevant state data includes information about a display that has an effect on color, such as a framebuffer driver state, a display driver state, and phospher characteristics of the display.

Abstract: Methods and apparatuses for processing media data for transmission in a data communication medium and for use with data processing systems. One exemplary method processes readable content stored in a stream or set of data which contains samples for presenting a presentation (e.g. video only or audio only or video and audio together) at a plurality of scales of scalable content. A second stream is derived from a first stream, where the second stream contains references to the first stream for use in selecting data, for an operating point within the scalable content, from the first stream. In one aspect of this method, references contained in the second stream are accessed to transmit or store the data from the first stream.

Abstract: A plurality of separately keyed padlocks, ranging in number from 7 to 150 or more, are securely held within a circular assembly that is rotated for selection of a specific padlock. This assembly of locks can be placed at a level for easy reach from a car window. Visible imprinted numbers provide a quick way for authorized members of a group to locate the padlock which a specific key will open. When opened and the padlock is turned opposite a slotted bar, moving the bar actuates a separately installed automatic gate-opener for access to an area. Alternatively, the system can be adapted for use manually by authorized personnel to lock or unlock a gate, door, or secured equipment. No padlock can be removed from the assembly except for periodic changing of a lock when an individual leaves the group and thus is no longer permitted to enter the closed area.

Abstract: A sliding bar contains a slot on one end so that bar movement passes shackle rods of an opened padlock. The bar is positioned on a rigid arm extending from a column that also supports a plate which can be rotated. Shackles of multiple padlocks are held uniformly on the plate. Shape of bar is such that its effective movement cannot occur when padlocks are closed. When a specific padlock is opened with its required key and rotated so its lengthened shackle rods are in front of the bar, movement of bar can occur. The slot allows sufficient bar movement to actuate a powered gate-opener, release a gate latch, or initiate other action. Imprinted numbers identify each padlock, and a pointer aids shackle-arm location in front of slotted bar. Advantages include security, access from car-windows, identifying unauthorized key-holders, and elimination of multiple key replacements when only one lock is used. Equipment size can vary so as to service between 7 and more than 150 authorized individuals.
