Patent EP-0295475-A3 (EP)
IPC: H04L29/00
Filed: 1988-05-27
Abstract: Each network node in a communications network maintains its 
own copy of the network topology database defining network 
resources. Each resource record contains a "timer" field 
which is initially set to a maximum value but which may be 
decremented on a daily basis. If the timer field is 
decremented to zero without being reset, the node 
unilaterally removes the resource record from its copy of 
the database. The timer field will normally reach zero only 
for obsolete resource records since each network node 
responsible for a resource broadcasts a timer-resetting 
message for the resource (1) each time the resource status 
changes, (2) when the node first joins or rejoins the 
network, and (3) on a periodic (weekly) basis regardless of 
whether conditions (1) or (2) have occurred.

Title: Grinding wheel for plunge-cut grinding
IPC: B24D7/14
Filed: 1989-02-02
Abstract: The grinding wheel (2), which is intended in particular for plunge-cut grinding, has a first abrasive-layer part (5) which contains fine-grained diamonds as well as a further abrasive-layer part (9) which contains larger diamond grains. This grinding wheel can be a straight wheel as well as a cup wheel. Known embodiments of such grinding wheels either cannot obtain the required surface roughness or exhibit high wear, since they do not have a continuous high proportion of diamonds in the outer marginal area of the end face as protection against rounding-off of the outer edge. In order to remedy this, provision is made for the abrasive-layer part (9) to be provided with diamond grains of larger grading which are arranged in a single layer parallel to the axis of rotation of the straight wheel, the diamonds being arranged at right angles to the axis of rotation in several layers and being held in mutual contact in an electro-deposited bond (10).

Patent EP-0348614-A3 (EP)
IPC: G06F12/00
Filed: 1989-04-15
Abstract: A shared file environment permits multiple users to 
read a file that is being updated concurrently. The 
process maintains N level shadows for a file to allow 
multiple users to read a file even though that file may 
be updated by one or more updaters in succession. A 
reader of a file does not need to wait on an updater of 
the file nor does the reader see any updates as they 
are being made. Each reader that opens the file sees 
the latest committed level of the file; that is, if 
reader A opens the file for read before updater B 
commits his changes, then there will exist one level 
shadow for the file after B commits. The process 
maintains N level shadows for a file, although only one 
updater of a file is allowed at a time. A new 
construct, referred to as the Not Available Yet (NAY) 
structure, contains entries for all files that are 
currently open for read. The NAY structure has an entry 
for each level of a file that is open for read. A 
counter associated with the entry indicates the number 
of readers of that level of the file. These entries are 
anchors for a list of block numbers of shadow blocks 
that cannot be unallocated because there is at least 
one reader of that level. A logging procedure allocates 
and unallocates blocks to track the N-level shadow 
blocks.

Patent EP-0355286-A3 (EP)
Title: Checkpoint retry mechanism
IPC: G06F9/38
Filed: 1989-06-08
Abstract: An improved checkpoint retry mechanism is disclosed 
which automatically updates checkpoint addresses to 
enable the retry of instruction sequences for shorter 
segments of recently executed code, in response to the 
detection of an error since the passage of the current 
checkpoint. It does this by updating three different 
types of checkpoint addresses, a first checkpoint address 
for the instruction which follows a memory write or I/O 
write operation, a second type checkpoint address for 
the first instruction in an interrupt service routine, 
and a third type checkpoint address for the first 
instruction in an interrupted routine following an 
interrupt event. The resulting checkpoint retry 
mechanism is more efficient and faster because it 
adaptively updates the checkpoint address to reduce the 
size of code segments which must be reexecuted during 
retry operations. The invention operates to avoid 
memory corruption and erroneous I/O outputs during 
retry operations and protects from erroneous retry 
sequences.

Patent EP-0353759-A3 (EP)
IPC: H04B17/00
Filed: 1989-08-03
Abstract: In an exemplary embodiment, a test signal is sent 
by a base station at a suitable point in a communi­
ications protocol. According to the evaluation of the 
test signal transmission, a relatively high data rate or 
a lower more conservative data rate is selected by a 
mobile unit for the transmission of a relatively lengthy 
data message. The test signal can be associated with a 
query from a mobile unit having a message to send, or 
with a contention polling message from the base. Such 
test signal can be transmitted at the lower data rate 
where its transmission characteristics (e.g. signal 
strength, jitter or quality of transmission of known 
information) can be used to predict probable feasibility 
of transmission at the higher data rate, but most 
preferably the test signal is part of a high data rate 
contention poll which may alternate with a low data rate 
contention poll.

Abstract: The toe piece binding (1) has a support bearing (13) which is mounted rotatably in lateral bearing blocks (7), fixed to the ski, and on which the ski boot (14) rests with positive fit in the touring position. To achieve this positive fit, the boot sole has a recess (22) which is matched to the support bearing (14) constructed as a straight shaft, and in which the support bearing fits. Serving for fastening the boot on this support bearing is a tightening lever (9) which is mounted so as to be swivellable by means of tensioning struts (8) and has at its one end a pressure piece (10) which presses onto the projecting edge of the boot sole (11) in its closed position in which the tightening lever is in an after-dead-centre position. For downhill skiing, the boot is placed directly on the ski and the tightening lever (9) is swivelled below the support bearing (13) and has at its end opposite the pressure piece (10) a holding-down device (12) for the sole which grips over the upper sole edge in the downhill skiing position. In order that the tightening lever mounted so as to be swivellable on the tensioning struts cannot escape upwards, it is held by the support bearing (13), below which it is swivelled for the downhill skiing position.
