Patent EP-0438229-A2 (EP)
Inventor: WHITE LISA K
IPC: G05D1/08
Filed: 1991-01-10
Abstract: A method for East/West stationkeeping of a geostationary satellite maintains the osculating value of longitude from exceeding a specified deadband for a specified drift period between maneuvers. In the planning, the mean longitude, the mean drift rate and the mean eccentricity vector are calculated and then maneuvers are executed to maintain the values below a magnitude such that the osculating longitude will be within the specified deadband over a specified drift period. The target conditions are achieved through a plurality of maneuvers which initiate a period of free drift which lasts for a specified number of days. During the free-drift period, longitude remains within its deadband, and no additional maneuvers are needed or are performed. The method has the advantage that it can take into account limitations on thruster on-time by allowing for a generalized number of stationkeeping maneuvers.

Abstract: A small tube (13) satisfying the following formula is fixed to the opening (for enabling the insertion of sensor, etc.) provided at the bottom or sidewall of a superconducting tubular material for magnetic shielding comprising a bottomed tubular substrate (20) and an oxide superconducting layer (21) formed on the substrate:       L/R ≦ L₁/R₁           
 wherein L is a distance from the top end of the tubular material to the small tube, i.e. the opening of the tubular material; R is an inside diameter of the oxide superconducting layer in the tubular material; L₁ is a length of the small tube; and R₁ is an inside diameter of the oxide superconducting layer in the small tube. An oxide superconducting layer is formed on the small tube contiguously to the oxide superconducting layer (21) formed on the bottomed tubular substrate. The resulting superconducting tubular material for magnetic shielding restricts the penetration of a magnetic field into the tubular material through the opening.

Abstract: The heat exchanger (10) consists of congruent planar elements (16) stacked one upon another at a distance (a) by means of inserted or integral projecting spacers. For the purpose of forming inflow cross-sections (30), these planar elements are cantered twice at right angles in the same direction on the mutually opposite sides, and turned by 90<o> to one another in each case. The cantered limbs (16') embrace the nearest planar element (16). Three of these planar elements (16) form in each case two adjacent flow ducts (34, 36) having flow directions (20, 22) intersecting at right angles. At least on the inlet side (E) of the medium flows (20, 22), the inflow cross-sections (30) are folded in for the most part without changing the external dimensions of the heat exchanger (10). The inflow cross-sections (30) remain unfolded only in the region of the edges (28) extending vertically relative to the planar elements (16). In each case, at least one adjoining planar element (16) is clamped in a sealing fashion in the longitudinal fold (24). <IMAGE>

Abstract: Method and apparatus are disclosed for dedicating one or more second lines interconnecting a public/private communication system (PCS), such as a Private Branch Exchange (PBX), and a Voice Mail System (VMS) for only providing message notification to communication devices of recipients of voicemail messages via the PCS. A plurality of analog first lines in a hunt group between the PCS and the VMS permit voice communications between callers and the VMS via the PCS. The VMS includes an applications processor which is integrated (coupled) to the PCS. The applications processor determines if a second line to be used only for message notification is part of the plurality of analog first lines in the hunt group. If the second line is part of the plurality of analog first lines, the applications processor accesses the PCS over the second line, and causes the second line to be made inaccessible to the public/private communication system for transmitting incoming calls to the Voice Mail System. When a second line is not part of the plurality of analog first lines, the applications processor accesses the PCS, and causes all incoming calls that are directed to the VMS over this second line to be forwarded to the plurality of analog first lines.
