Title: Passive paper takeup for rolled paper
IPC: B65H18/00
Filed: 1989-11-24
Abstract: An apparatus for passively rolling a strip of paper (12) is 
disclosed. The apparatus is generally used with a strip chart 
recorder. As the strip of paper (12) discharges from the recorder 
housing (16), it is fed into a guide (16) which guides the paper (12) 
into a cylindrically shaped paper container (40). The guide (46) 
stiffens the paper (12) by imparting a slight bow across the 
paper (12). The paper (12) has a predetermined direction of curvature, 
imparted to the paper (12) by being stored in a roll (34). The stiffening 
of the paper (12) by the guide (46) allows the strip of paper (12) to 
be pushed into the cavity (44) and ensures that the paper (12) will 
curl in the predetermined direction of curvature as it enters the 
cylindrical cavity (44).

Patent EP-0399571-A3 (EP)
IPC: H04L12/413
Filed: 1985-07-25
Abstract: An optical communication system including repeaters (5-1 
to 5-n) which return a preamble signal to a receive line 
(2) as soon as it detects a carrier on a transmit line 
(1) of a single line optical bus (1,2,6). Therefore, 
transmission equipment (7-1 to 7-m) can confirm data 
transmission quickly because the time delay between data 
transmission and its confirmation is decreased. The 
repeater (5-1 to 5-n) also monitors a time delay assoc­
iated with the return through a return loop (6) of the 
transmitted data, and produces and transmits a failure 
signal when the time delay is longer than a predetermin­
ed value. The system also includes an optical trans­
ceiver (10-1 to 10-m) connected between the optical bus 
and the transmission equipment (7-1 to 7-m) which con­
verts optical signals into electrical signals and vice 
versa and also adds the preamble signal to the front of 
data to be transmitted.

Title: Method and apparatus for thermodynamic cycle
IPC: F01K25/00
Filed: 1990-01-11
Abstract: A composite stream, having a higher content of a 
high-boiling component than a working stream, is used to provide 
heat needed to partially evaporate the working stream. After 
being partially evaporated (heat exchanger 214), the working 
stream is evaporated completely with heat provided by returning 
gaseous working streams (heat exchangers 251,252) and heat from 
an auxiliary steam cycle (heat exchanger 250). After being 
superheated (heater 201), the working stream is expanded in a 
turbine (202). Thereafter, the expanded stream is separated 
(separator 231) into a spent stream and a withdrawal stream. The 
withdrawal stream is combined (at 241) with a lean stream to 
produce the composite stream. The composite stream (in heat 
exchanger 212) partially evaporates the working stream and 
preheats the working stream and the lean stream. A first portion 
of the composite stream is fed into a distillation tower (225). 
A liquid stream flowing from the distillation tower (225) forms 
the lean stream that is combined with the withdrawal steam. A 
vapor stream flowing from the distillation tower (225) combines 
(at 246) with a second portion of the composite stream to produce 
a pre-condensed working stream that is condensed (condenser 221) 
forming a liquid working stream. The cycle is complete when the 
liquid working stream is preheated (heat exchangers 228,217) 
prior to being partially evaporated.

deformation of the rear surface of the backing layer, 
when the cutting element is heated during the bonding 
process, the rear surface (15) is made initially concave 
at ambient temperature. Alternatively, or additionally, 
the co-operating surface (18) of the carrier may be concave.

Title: Yarn piecing method and yarn piecing apparatus
IPC: D01H4/48
Filed: 1990-03-06
Abstract: In a spun yarn forming textile machine, when a 
spun yarn delivered from a yarn forming device (2) at a 
predetermined constant speed and a yarn withdrawn from 
a yarn package (80) are pieced to each other, a splicer 
(71) is used as a yarn piecing means (7). After 
withdrawing a yarn from a yarn package (80) with a 
predetermined length, the yarn piecing operation is 
carried out. Rotation of the yarn package is started 
before the yarn piecing operation is completed. 
Therefore, snarling can be prevented and the 
construction of the yarn storing means (75) can be 
simplified.
