摘要： A system for stabilizing two antennas on a mobile platform, the antennas including a first antenna associated with a first geo-stationary satellite and a second antenna associated with a second geo-stationary satellite, the system comprising an upper alignment system and a lower alignment system. The upper alignment system is configured for being a common support for the antennas. The upper alignment system has an intermediate element. The upper alignment system is configured for pointing the antennas relative to the intermediate element, such that the angular displacement between the antennas is matched with the angular displacement between the satellites. The lower alignment system is connected to the upper alignment system and the mobile platform. The lower alignment system is configured for maintaining the orientation of the intermediate element in order to compensate for rotation of the mobile platform, such that the antennas are maintained pointing toward their respective satellites.

摘要： A press cage may include pairs of opposing wall plates, each of the pairs of wall plates being orthogonal with respect to the other pairs, with corresponding machined indentations located at predetermined locations on broad faces of the wall plates which are adjacent to each other. The press cage may also include coupler assemblies made of coupler parts, each of the parts fixed to machined indentation of the corresponding machined indentations at one of the predetermined locations, the coupler parts locked together.

摘要： A device and method for measuring an optical characteristic of a fluid. The device, typically a densitometer includes a set of optical elements that include a light source, a collimating lens, a focusing lens, and a receiver, wherein a gap exists between the collimating lens and the focusing lens so as to allow the fluid to pass in between the lenses, and wherein at least one of the optical elements is tilted with respect to an optical axis.

摘要： Apparatus for registering a copy sheet prior to feeding the sheet to the image-transfer station of an electrophotographic copier. Opposing pairs of relatively rigid feed rollers are arranged on shafts in alternating relationship with opposing pairs of relatively compliant feed rollers, which are of somewhat larger diameter than the rigid rollers so as to form nips of appreciably greater extent in the direction of feed. Registration gates mounted for rotation on one of the roller shafts through slipping couplings are selectively restrained against rotation with the roller shaft either in a non-blocking position out of the feed path or in a blocking position within the nip area of the compliant rollers but upstream of the nip area of the rigid rollers. A crimper comprising an anvil rotating with one of the registration gates and a hammer supported by the anvil for pivotal movement into a recess in the anvil deforms a leading edge portion of the copy sheet as it is advanced from the registration rollers to facilitate separation of the sheet from the photoconductor after image transfer by a pickoff element spaced from the photoconductor.

摘要： A device, system and method to measure an optical characteristic of a fluid, the device including a plurality of components consecutively arranged and coupled together via quasi kinematic or kinematic coupling. The consecutively arranged components define a void within the device. The void encloses a measuring set-up for measuring at least one optical characteristic of a fluid passing through a gap. The gap is located at an intersection between an optical path of the measuring set-up and a flow path of the fluid.
