Title: Connection-Oriented Network Using Distributed Network Resources and Predetermined VPIs for Fast VC Establishment
Inventor: IWATA ATSUSHI
IPC: H04L12/70
Filed: 1994-12-28
Abstract: In a connection-oriented network, a normal signaling packet is sent from a source user to the network. A first virtual path identifier (VPI) is determined at a first node of the network according to a destination address in the packet, and the first VPI is inserted into the packet, and forwarded to the second node, where it determines a second VPI according to the packet's destination address, adds the second VPI to the first VPI in the packet to produce a source route, and forwards the normal signalling packet to a destination user. The destination user returns an acknowledgment (ACK) packet to the source user, containing the source route. In response ko the ACK, the source user stores the source route contained in the packet into a source route table, and selects an initial VPI and an initial virtual channel identifier (VCI) from a copy of network resource, and sends a fast signaling packet, captaining the source route, the initial VPI and VCI. At the first node, a first VCI is selected according to the first VPI in the source route of the fast signaling packet, the initial VPI/VCI in the packet are mapped to the first VPI/VCI, and the initial VCI in the packet is overwritten with the first VCI, and the packet is forwarded to the second network node, where a second VCI is selected according to the second VPI in the source route of the packet, and the first VPI/VCI in the packet are mapped to the second VPI/VCI, and the first VCI in the packet is overwritten with the second VCI, and the packet is forwarded to the destination user.

Title: Heatable roll for the treatment of webs of material as well as method for their operation
Inventor: CONRAD HANS-ROLF
IPC: F16C13/00
Filed: 1995-05-25
Abstract: A jacket with a thermally insulating layer partially surrounds, at a small spacing, a heatable roll which serves for the treatment of webs of material, in particular paper webs. Under production conditions the jacket reduces heat losses from the roll through convection and radiation to the environment. The jacket has a device which, with an interruption of production, ensures a forced convection at the heated roll for the cooling of the surface to a temperature level which is same or only insubstantially higher than in the production state.  Several cooling nozzles are conceivable for the said apparatus which are secured to the jacket and direct a coolant onto the roll surface.
Patent CA-2153273-A1 (CA)
Inventor: HOANG CHINH L
IPC: H03K3/03
Filed: 1995-07-05
Abstract: An oscillator system and method in which a time period (inverse of frequency) of a multi-stage ring oscillator (ROSC) is adjusted by a bias current which controls the charging and discharging times of respective capacitors (e.g., interelectrode capacities) within each stage.  The time periods of the unadjusted oscillator are counted along with the time periods of a reference clock over a same period of time and a count difference between the two counts is determined.  The count difference is applied by a logic circuit in accordance with an algorithm relating count differences to incremental bias current levels to adjust the frequency of the oscillator.  The logic circuit generates digital gate signals corresponding to the count difference and these signals automatically select the bias current level needed to bring the oscillator frequency into close agreement with the reference clock frequency.  The digital gate signals are stored in a non-volatile memory so that the oscillator will continue to operate at the adjusted frequency (i.e., that of the reference clock) even if the reference clock is no longer present and power is temporarily removed.  The oscillator system is well suited for implementation by complementary metal oxide semiconductor (CMOS) technology as part of an integrated circuit (IC).

Title: Process printing material and device for reproducing holographic fine structures and other diffraction grids on print products
Inventor: MATTHIESEN JOHANNES
IPC: B41M1/24
Filed: 1993-02-10
Abstract: The description relates to a process for the simulta-neous replication and direct application of holograms and other diffraction grids on various printing material (6), especially paper or cardboard. It is carried out in the shaping process using a matrix bearing the hologram as a surface relief structure. One or more coats of lacquer (3, 7, 9) are applied to a printing material (6) with a sub-stantially smooth surface and thus the surface of the printing material (6) is smoothed further. The hologram is simultaneously shaped into the surface of the coating applied to the printing material (6). The lacquer coating (3) can be hardened by radiation and the lacquer costs (3) are hardened from the matrix side through the UV-transpar-ent matrix and through a matrix support (14) (a plate or cylinder) which is also UV-transparent.  The lacquer coat(s) (3, 7, 9) is/are essentially hardened before the printing material (6) is removed from the matrix and in contact with the matrix or the shaping cylinder.

Title: Method and Apparatus for Repairing Damaged Tubes
Inventor: FINDLAN SHANE J
IPC: B23K26/34
Filed: 1994-02-10
Abstract: Disclosed is a laser beam welding technique which can be utilized to accomplish clad welding and repair of the internal surface of a tube. The technique uses the addition of filler metal to build up the internal surface of the tube. The apparatus includes a laser energy source connected to an elongated weld head by an optical fiber. The elongated weld head is rotatable and contains a mirror canted at a forty-five (45) degree angle. The laser beam generated by the laser source enters the weld head through a rotary joint, passes through focusing lenses, and is reflected to the interior surface of the damaged tube by the canted mirror. Means are provided to rotate the weld head which causes the beam to travel circumferentially around the interior of the tube. Means are also provided to feed metal fill material to the location where the focused beam contacts the interior surface of the tube. The result is a smooth clad welding repair on the inside surface of the tube which restores the strength of the tube and leaves no crevices for future corrosion attack. In addition, the internal diameter of the tube is very close to the original diameter of the tube thus obviating pressure drop associated with the sleeving type repair and allowing for subsequent repair of the tube at positions beyond the first area of repair.

Filed: 1995-10-27
Abstract: A shield that is normally positioned or wrapped around a boiler tube when such tube is exposed to extreme operating conditions.  This shield consists of an elongated strip of thin material that is formed as a helix.  This strip also incorporates a means for spacing this strip from the tube so as to create a gap between the tube and the shield.  Generally the shield is secured  to  the  tube  by  spot  or  button  welding  only  the longitudinal end regions of the strip to the tube.   By thus wrapping and securing one or more such shields to the tube, the tube  is  protected while  still  permitting  both  it  and  the shield(s) to expand and contract as needed.

Abstract: A process is disclosed for recovering chips and fibres from residues of timber-derived materials, old pieces of furniture, production residues, waste and other timber-containing materials glued with urea-formaldehyde binders or other binders capable of being hydrolysed or chemically disintegrated by disintegrating the timber-derived materials at a high temperature. In a first step of the process, the residues of timber-derived materials are impregnated with an impregnating solution and previously swollen until they have absorbed at least 50 % of their own weight of impregnating solution. In a second step, the thus impregnated residues of timber-derived materials are heated up to 80 °C to 120°C. The thus disintegrated residues of timber-derived materials are then sorted by sieving and/or wind screening. The residues of timber-derived material have edges of at least 10 to 20 cm length. In an improvement of the invention, the residues of timber-derived materials are impregnated and heated at the same time.
