cylinder (C) to yield to large lumps passing between the 
cylinders. A chute feed (10) and coiler (192) are uniquely 
combined with the compact arrangement in a minimum of space 
and in a mobile construction so as to permit movement of 
either the chute or coiler away for access to the apparatus. 
The compact upstanding arrangement provides for mounting of 
a number of carding elements mounted about the two cylinders 
which include stationary plates (40, 42, 44, 46) on cylinder 
(B); and revolving flat assembly (E) and stationary carding 
plates (96, 123) on cylinder (C). An extended fiber path (P) 
is defined about cylinders (B) and (C) along which a 
transferred fiber mass may be effectively exposed for carding 
on both of its sides. Fibers may be subjected to a carding 
action over approximately 80 percent of the circumference of 
the carding cylinders. Automatic thread-up of a sliver 
produced on the carding apparatus is provided by perforated 
transport belts (150, 152) which collect a web (W) and 
condense it into sliver (S). Sliver (S) is subjected to

Title: Adaptive data link protocol
IPC: H04L1/18
Filed: 1989-12-11
Abstract: A communication system provides high speed trans­
mission of data over a link, such as a fiber optic 
link, between a first terminal and a second terminal. 
The architecture and protocol permits the use of 
dedicated hardware such as state machines constructed 
of programmable array logic units, to synchronize the 
transmission and reception of data packets and the 
retransmission of designated ones of these packets in 
the event of a faulty transmission. Packets to be 
transmitted and received are stored in an array of 
frames in sub-windows of a memory storage window in 
each of the terminals, the frame number being equal to 
the sequence number of the data packet. By embedding 
sequence and status bits in each packet within control 
words and bits appended to each packet, the state 
machine in each terminal can readily track the 
progress of each packet so as to request acknow­
ledgement of error-free receipt, to send an acknow­
ledgement, to request a retransmission of a packet 
designated by its serial number, and to distinguish a 
retransmitted packet from an original packet trans­
mitted with error.

Patent EP-0333365-A3 (EP)
Title: Method and apparatus for handling asynchronous memory management exceptions by a vector processor
IPC: G06F17/16
Filed: 1989-03-06
Abstract: A data processing system handles memory management 
exceptions caused by a faulting vector instruction in a vector 
processor by halting the execution of the faulting vector in­
struction being executed when the exception occurred and by 
setting the state information for the vector processor to 
acknowledge the presence of the exception and to include informa­
tion about the suboperation of the vector instruction being exe­
cuted when the exception occurred. The scalar processor is not 
interrupted at this time, however. Any other vector instructions 
executing simultaneously with the faulting vector instruction are 
allowed to continue so long as those instructions do not require 
data from the faulting instruction. The faulting partially com­
pleted vector instruction resumes execution after the operating 
system has processed the memory management exception.

Title: Embedment of data in a video signal
IPC: H04N1/04
Filed: 1989-09-22
Abstract: Data is embedded in a video signal by adding a low 
level waveform to the video signal, the low level 
waveform having a level below the noise level of the 
video signal and corresponding to the data. To detect 
data embedded in the video signal the video signal is 
correlated with the low level waveform corresponding 
to the data to produce a correlation coefficient. A 
high correlation coefficient indicates the presence of 
the low level waveform which is converted into the 
data. The low level waveform extends over many video 
lines such that it does not occur at or near the same 
position within a video frame for many video frames to 
avoid fixed-pattern noise anomalies that may be 
detected by a viewer of the television picture.

Patent EP-0375361-A3 (EP)
Title: Duplex communications method and system
IPC: H04W88/02
Filed: 1989-12-19
Abstract: A method of establishing a digital time-division 
duplex radio communication link between one of 
a plurality of portable units and a base unit in a 
cordless telephone system. Transmissions from the 
base unit are allowed only on a ping-pong basis with 
transmission bursts from all the active transmitters in 
the base unit being synchronised with one another. 
This prevents blocking of receiver sections due to co-sited 
transmitters transmitting at the same time on a 
different channel. The difficulty of synchronising 
the transmission bursts of the active portable units 
with their respective transceivers within the base unit 
is overcome by allowing the portable unit to make an 
initial continuous call comprising multiple identical 
sequences of data containing units small enough to be 
completely received within the limited reception 
windows of the base unit. After the initial call has 
started communication, an exchange of signals takes 
place on a ping-pong basis to establish synchronism 
between the portable unit and base unit. Finally, if 
all is well, the system reverts to speech mode.
