Patent DE-19930506-A1 (DE)
Inventor: HAAK BERTRAM
IPC: B65D5/496
Filed: 1999-07-04
Abstract: The invention relates to a one-piece foldable protective sheath for locating separately several objects. A variable number of objects to be protected can be selectively arranged one after the other or in different spatial arrangements using said single protective sheath. Several individual sheaths can be simultaneously unfolded and unfolding can effected mechanically. The basic surface (37) of the unfolded protective sheath is marked by parallel fold lines (2-7), which form the corners of the protective sheaths and which are subdivided rectangularly in relation to the fold lines by a sequence consisting of web of material (16), punching line (18), perforation line (35), punching line (17), web of material (15), web of material (13), punching line (10), perforation line (14), punching line (11), web of material (12), on which the unfolded protective sheaths can be bent. To this end, the surface between both adjacent webs of material (13, 15) is interrupted parallel to the fold lines (2-7) and up to a lateral edge. The protective sheath provides quick unfolding and increased variability due to the fact that the number of objects can be modified and the arrangement of objects relative to one another can be altered.

Abstract: The present invention relates to a process of preparing syndiotactic styrenic
polymers with a high conversion rate in the form of fine powder, which comprises
(a) preparing styrenic polymers in a solid state by reacting a mixture consisting of
styrenic monomers, a metallocene catalyst, a cocatalyst and inert organic solvent
in a polymerization reactor, (b) separating a portion of the styrenic polymers from
the reactor, (c) recycling the portion of the styrenic polymers in the reactor, and
(d) reacting the recycled styrenic polymers with styrenic monomers. The styrenic
monomers may include olefinic monomers. The monomers can be introduced to a
single inlet or multiple inlets of the reactor. A single reactor or a plural number of
reactors can be operated in the present invention. The plural numbers of reactors
are arranged in series or in parallel. In the present invention, a self-cleaning
mono- or twin-axis reactor can be employed to prevent the polymers from
agglomerating on the inner wall or the axis. Alternatively, a cylindrical reactor
can be employed, where the styrenic polymers are transported in a solid or powder
state rotating in a certain direction at the range of Froude Number of from 0.1 to
10 and polymerization proceeds toward the exit of the reactor.

access control device admits the computer to the
network if the response is identical with the check
value, and in that the algorithm is geared such that
any result from the algorithm can be derived from a
plurality of possible input parameters of the

elongate drive element is trained around the plurality of pulleys and operably
connected to the first and second drives so that simultaneous operation of the first
and second drives and variation of the drive directions of the first and second
drives allows the elongate drive element to be moved so as to cause the object
movement imparting assembly to move in the first and second paths and the first

Inventor: ADAMS LAURA ELLEN
IPC: H04B10/275
Filed: 2000-06-06
Abstract: A dual-ring, bi-directional optical fiber transmission system interconnects a
series of add/drop nodes with a hub, such that multiple, widely spaced coarse
wavelength division multiplexed (C-WDM) channels are established on each ring.
At each node, an optical add/drop module (OADM) includes broadband filters
(BBF's), such as dielectric thin film filters, arranged to (a) extract, for the purposes
of a receiver, or (b) insert, for the purposes of a transmitter, information in one or
more of the channels. The signals in the one or more channels are coupled to the
OADM's by a standard optical transceiver, which performs modulation and
demodulation. Each filter passband can be populated with multiple dense
wavelength division multiplexed (D-WDM) channels, so that the capacity of traffic
that can be handled at each node can be easily upgraded. The transceiver is, in turn,
coupled to packet framer, such as an IP packet over SONET framer, which supplies
received packets to, and receives outgoing packets from, a conventional Layer 3
routing engine. While in most instances, endpoints at each of the nodes
communicate with other endpoints connected to the hub, if desired, endpoints at one
or more nodes can communicate directly with endpoints on other nodes, using a
direct or bypass connection through the hub. The bypass can be "permanent" or
controlled via a switch, such as a micro-electro-mechanical switch (MEMS).
