Abstract: A method of treating wood-fibre pulp, particularly wood-fibre pulp that contains recycled paper, comprises delivering the pulp to and advancing the pulp in a heating zone while delivering steam to the heating zone. The pulp is finely-divided in a disperser and the finely-divided pulp delivered to a screw press without separate departure of steam, so as to compact the pulp in the end of the screw press and therewith form a plug seal. At the same time, one or more bleaching chemicals is or are supplied during one or more treatment stages, and the temperature of the pulp is regulated to obtain an optimal bleaching process or optimal bleaching processes. The temperature of the pulp can be raised or lowered by supplying steam or water thereto respectively. The invention also relates to a plant for carrying out the method.

Inventor: BOEHM REINHARD
IPC: C23C4/12
Filed: 1999-02-22
Abstract: An arc spray gun has a pair of tubular wire guides that guide two metal wires to a point of contact at the wire tips where an arc current through the wires effect an arc, thereby melting the tips. Primary gas channeling on a central axis issues a primary gas flow that atomizes the molten metal and effects a spray stream thereof. A gas cap has at least four orifices arcuately spaced equally about the central axis. The orifices direct secondary gas jets inwardly with a forward directional component toward a point of intersection of the orifice axes on the central axis. The point of intersection is located proximate the point of contact and spaced downstream therefrom sufficiently for the jets not to interfere substantially with the atomization. The spray stream thereby is constricted and accelerated by the secondary gas jets.

Patent CA-2275456-A1 (CA)
Title: System and method of time and frequency synchronization in a radio communication system
Inventor: DENT PAUL W
IPC: H04L7/04
Filed: 1997-12-17
Abstract: A communication station such as a hand-held telephone quickly identifies a desired carrier signal or time slot of a carrier signal and synchronizes itself in time and frequency to that carrier or slot.      Synchronization is achieved even when frequency and time reference signals in the communication station are offset, e.g., due to drift, with respect to the carrier signal or slot by averaging successions of signal measurements that occur at times when corresponding signal values are expected.      In one method, a plurality of measurements of the received signal taken at a group of predetermined time points where corresponding values are expected are averaged together, in order to enhance the signal to noise ratio. Averaging is carried out several times using different groups of time points, the groups corresponding to respective, different expected clock frequency errors.  The results of the averaging steps are used in determining a best hypothesis for the received signal. Dynamic programming is used to test synchronization hypotheses based on different hypotheses of timing drift rate and to discriminate between different hypotheses of timing and timing drift rate in order to maximize sums of correlations.

An axial relative movement, is permitted between the guiding ring 18 and the bearing ring 23. The guiding ring 18 ensures that the protective cone 10 with the folds 15 is well supported under conditions of articulation.      Furthermore, the assembly allows the protective cone 10 to have a relatively long length provided with folds 15, without losing any of its stability.

Inventor: RAKIB SELIM SHLOMO
IPC: H04B1/71
Filed: 1999-09-09
Abstract: A narrow band interference excision circuit for use in broadband digital data communication systems such as CDMA systems. The excision circuit is comprised of a matrix of polyphase filters that divide the input signal into a plurality of narrow subbands. Each narrow subband signal is examined to determine if narrowband interference exists in that bin. This is done preferably by taking the average of the absolute amplitude of the signals in the bin. If a signal in a bin has an absolute amplitude which far exceeds the average in the bin, the entire bin signal is eliminated. A bank of polyphase synthesis filters reassembles the composite signal. An equalization circuit with an error predictor comprised of an adaptive FIR filter and a correlator is coupled to adapt coefficients of the filter to colored noise and generate a colored noise cancellation signal to remove colored noise from the input to the slicer.

Abstract: A presentation board digitizer system for large boards preferably employs at least three spaced-apart ultrasound receivers assemblies. A current position of an ultrasound transmitter is assigned as a weighted centroid of time-of-flight position measurements based on at least two pairs of receiver assemblies. The weighting used varies as a function of the transmitter across the board. A preferred structure of an ultrasound receiver assembly for use in the system employs a pair of ultrasound receivers arranged side-by-side in a line perpendicular to the surface of the presentation board. The receivers are connected so as to generate a total output signal corresponding to the instantaneous sum of the ultrasound signals received at each, such that the receiver assembly is most sensitive to ultrasound signals incident from a plane adjacent to the presentation board. Also described are a transmitter device for use with a conventional pen in which the ultrasound transmitter is a cylindrical element lying coaxial with the pen and adjacent to its tip, and a jointed eraser structure.

Title: Method and composition for producing activating light absorbing lenses
Inventor: BUAZZA OMAR M
IPC: B29C35/02
Filed: 1998-07-31
Abstract: An eyeglass lens forming composition containing light absorbing compounds which may undergo light initiated polymerization is provided. Typically, lens forming compositions that absorb light do not permit enough activating radiation to penetrate into the depths of the lens cavity to adequately initiate polymerization of the lens forming composition. An embodiment of the invention provides a system and method for curing such a lens forming composition to form a lens that does not transmit activating light. Activating light is used having a wavelength greater than the wavelengths of light which the light absorbing compounds absorb. The power of the formed lenses may be controlled by varying the lens forming conditions. Additionally, the lens forming process may be controlled using a microprocessor based control system.

Patent CA-2306283-A1 (CA)
Inventor: RENNER KLAUS
IPC: B65D81/32
Filed: 1999-08-05
Abstract: The invention relates to a multi-chamber container comprising cups (1.1, 1.2) which are covered by a common covering film (1.4). The cups are separated from one another by a connecting element (1.5)on which the covering film is sealed in such a way that, when applying pressure on one of the cups, this cup is interconnected to one or more adjacent cups by removing the covering film from said connecting element. The sealing strength on the common edge, over which the covering film and cups are interconnected, is selected such that it is high enough to prevent the connection between the covering film and the cups from detaching in the edge area due to this pressure. This solution establishes many examples for application especially with respect to the type and composition of the media accommodated in one of the cups. This can concern the use of liquid media. Applicators of different types, especially of types which expand when moistened, can be accommodated in the cups so that the multichamber container can also, for example, be directly used for the transdermal application of liquid active substances.
