Patent EP-0196859-A3 (EP)
IPC: F16D3/04
Filed: 1986-03-25
Abstract: A coupling for transmitting torque between two substan­
tially parallel shafts (particularly a driving shaft and a 
wheelset of a railway bogie) is arranged to accommodate a 
variable lateral displacement between the shafts, arising for 
example from oscillation of one of the shafts on its 
suspension. The coupling comprises a floating ring element 
(F) which is coupled to respective radially extending arms 
(LP, LQ) on the shafts (P, Q) by orthogonal pairs of parallel 
links (L). The links and ring element rotate with the shafts 
substantially in a common radial plane and the connection 
points between the links and ring element are so disposed 
that in use, the centre of the ring element orbits the shaft 
axes and, provided that the shaft axes are nearly coincident, 
the configuration of the ring element and links is substantial­
ly unchanged during the rotation.

Title: Apparatus and method for measuring dark and bright reflectances of sheet material
IPC: G01N21/47
Filed: 1989-03-21
Abstract: Apparatus (10) and methods for measuring dark and 
bright reflectances of translucent sheet material (2) are 
disclosed. The apparatus (10) comprises first optical 
means for illuminating one side of the sheet material (2) 
with a source of electromagnetic radiation. A portion of 
the radiation is transmitted through the sheet material 
(2) and another portion of the radiation is reflected by 
the sheet material. The apparatus (10) also comprises 
optical gating means (30) that is positioned adjacent the 
other side of the sheet material (2) in a fixed position 
relative to the first optical means. The optical gating 
means (30) absorbs substantially all of the transmitted 
portion of the radiation when switched to a dark state 
and reflects substantially all of the transmitted portion 
of the radiation back through the sheet material (2) when 
switched to a bright state. The apparatus (10) further 
comprises second optical means for collecting the 
reflected portion of the radiation and the portion of the 
trasmitted portion of the radiation reflected by the 
optical gating means (30) and retransmitted through the 
sheet material (2) to provide a total reflectance. The 
total reflectance has a dark reflectance intensity when 
the optical gating means (30) is in the dark state and a 
bright reflectance intensity when the optical gating 
means is in the bright state. The apparatus also 
 
 
comprises sensing means (60), responsive to radiation 
collected by the second optical means, for providing a 
dark signal having a magnitude corresponding to the dark 
reflectance intensity and a bright signal having a 
magnitude corresponding the the bright reflectance 
intensity. The dark and bright signals can be 
incorporated in known formulae to compute values for 
quality attributes of the sheet material (2) including 
opacity and color.

Abstract: Triphendioxazine reactive dyes have been found to be unsuitable for almost all conventional single-stage printing processes since these dyes are unstable under the conditions of said processes. 
<??>In the course of the development of an uncomplicated single-stage printing process for these dyes it has now been found according to the invention that by replacing the customary fixing alkali (NaHCO3) by stoichiometrically determined amounts of sodium acetate or sodium trichloroacetate or certain mixtures of sodium trichloroacetate with sodium acetate it is possible to fix triphendioxazine reactive dyes in full yields without hue change. Conventional print pastes may be applied at the same time.
