Title: Process for transferring data packets
Inventor: BRAUN WALTER
IPC: H04L45/42
Filed: 1990-03-20
Abstract: ABSTRACT OF THE DISCLOSURE         A process  for transferring data packets in a network having a master station (M), at least one sub-scriber  station  (T1,  T2,  T3,  T4)  and a common data channel, comprises the following steps:      a) each subscriber station (T1, T2, T3, T4) records the data packets received by it and the transmission quality levels (Q01, Q02,..) of said data packets; b) each subscriber station (T1, T2, T3, T4) reports the  recorded  transmission  quality  levels  (Q01, Q02,..) to the master station (M); c) the master station (M) determines at least one data routing for each subscriber station (T1, T2, T3, T4) on the basis of the transmission quality levels (Q01, Q02,..) reported to it; d) a data packet directed to a certain subscriber station is transferred according to the determined data routing.         The process  is particularly suitable  for the transferral of data packets via the supply lines of a medium- and low-voltage network.                                    (Fig. 2)

Title: High-efficiency gear transmission
Inventor: ZHENG YUE
IPC: F16H1/32
Filed: 1990-07-10
Abstract: Abstract High-Efficiency  gear  Transmission  of  the  present invention  relates  to  the  field  of  gear  transmission technique,  particularly  to  a  high-efficiency  double internal  gear planetary  transmission with  small  tooth number  difference.  High-Efficiency  Gear  Transmission of this invention provides with an entirely new double-ring  gear and extra  short  toothed  gears with changed gear  parameters  in  order  to  obtain  high  transmission efficiency with reduced power loss in bearings and gear engagement.  High-Efficiency Gear Transmission according to  the  invention  comprises  at  least  one  double-ring gear  composed  of  two  integrated  coaxial  gear  rings.          Said  double-ring  gear  having  different  tooth  numbers on each ring is mounted on an eccentric shaft through planetary bearings. The double-ring gear performs plane-tary movement  with  two  fixed-axle  gears  respectively.          The  vertical  projections  of  the  tooth width of the two gear rings of said double ring gear on their common axis at least partially coincide with each other.  Both said gear rings are composed of either outer or inner gears. The distance between the projections of the center lines of their tooth widths in the direction of their common axis is zero. The distance b between the internal surface of the outer gear ring of said double-ring gear and the external surface of the fixed-axle gear engaged with the inner gear ring of said double ring gear must be not less than twice the eccentric distance a of the eccentric shaft. If the double ring gear and the fixed-axle gears engaged with it are all helical gears,  the two  internal helical gears are of the  same hand,  and so are the two external helical gears.    The high-efficiency gear transmission  is provided with an extra short toothed gear pair with changed gear parameters.  Its  addendum coefficient  ha  is  less  than 0.5,  the  absolute  value  of  its  modified  coefficient difference  X  is not more  than 0.1, preferably equal to  zero,  and the modified coefficients  of  both extra toothed  gears  are  preferably  equal  to  zero.  The  two internal helical gears are of the same hand and so are the two external helical gears while said extra short toothed gear pairs are used for the two internal gear pairs of the double internal  gear planetary transmis-sion.

Abstract: In a process of phosphating metal surfaces phosphating solutions are employed which are substantially free of nickel and contain 0.3 to 1.7 g/l Zn 0.2 to 4.0 g/l Mn 0.001 to 0.030, preferably 0.003 to 0.020 g/l Cu to 30 g/l phosphate (calculated as P2O5) in which by oxygen and/or other equivalent oxidizers the concentration of Fe(II) is kept below 0.1 g/l and which are adjusted to a pH value from 3.0 to 3,8.      The weight ratio of Cu to P2O5 is preferably adjusted to 1 : (170 to 30,000) and Cu and P2O5 are preferably replenished in a weight ratio of 1 : (5 to 2000).      The phosphating solutions should contain 0.3 to 1.0 g/l Zn if they are applied by spraying and should contain 0.9 to 1.7 g/l Zn if they are applied by spraying/ dipping operations or by a dipping operation.

Title: Spar-to-hub joint for a flexbeam helicopter rotor
Inventor: BYRNES FRANCIS E
IPC: B64C27/48
Filed: 1991-05-14
Abstract: A flexbeam helicopter rotor having an improved connection between the flexbeam and the hub of the con-necting pin variety but in which the high tensile fi-bers of the flexbeam do not wrap around the connecting pin, wherein the blade centrifugal loads and the blade lead-lag loads axe reacted by the connecting pin at a station where it passes through drilled holes in the flexbeam inner end, and wherein the blade flapping mo-tion imposed loads are reacted through two load paths in the flexbeam-to-hub connection, the first load path being created by a prying reaction between the flexbeam and the hub connecting flanges, and the second load path being created by the differential bending reaction between the flexbeam at the station of the drilled holes and the connecting bolts. Further, there are means to decouple the loads and decrease the maximum load in at least one of the load paths created by the aforementioned prying reaction and the aforementioned bending reaction so that they are substantially spaced along the flexbeam axis of rotation from each other to thereby permit the use of a minimum thickness flexbeam, and gain the attended advantage of reduced rotor weight and size, and which flexbeam-to-hub connection has the additional advantage of a reduced flapping hinge ef-fecting offset, or flapping axis, from the prior art type of connection.
