Patent SE-8107590-L (SE)
Inventor: HEDIN J-E
IPC: B23D59/00
Filed: 1981-12-17
Abstract: The invention relates to a device for preventing length measuring errors resulting from accidentally remaining local offshoots from a portion of the butt end of a tree stem which is continuously advanced toward a cross-cutting member for cutting the stem in predetermined length sections. A stem-measuring device periodically emits a cutting impulse to the cross-cutting member so that the advancing stem will be cut into predetermined lengths. Two detectors are provided in a spaced relationship for sensing the entering of the butt end into a detecting station and then emitting an actuating signal to start the measuring device. The spacing of the two detectors, which are symmetrically positioned with respect to the centerline of the stem path, does not exceed a predetermined minimum butt diameter. The measuring device is not actuated until signals from both detectors are emitted. Thus, sensing of a local offshoot from the butt end by only one of the detectors does not start the measuring device with the result that the offshoot does not cause a shorter-than-desired length of stem.

Abstract: The invention relates to a process for bleaching chemically produced pulp with ozone, in connection with a defibration step. Whereas chlorine is used in existing bleaches, it has now been found that the bleaching step proceeds more economically and with less pollution of the environment if the pulp is treated with nitric oxide or nitric acid and ozone while it is subjected to a defibration step.

Abstract: Continuous pressure boiling of beer wort is carried out in a multistage column having an upright inner wall enclosing a head region near the top of the column, a sump region near the bottom of the column and a wort compartment between the head and sump regions. The wort compartment includes a plurality of superposed, substantially horizontal plates. Each plate is provided with an overflow weir on its upper surface with an opening between the overflow weir and the wall of the column. Regenerative preheated wort is charged onto an upper plate and flows downward from one plate to another over the overflow weirs and through the openings. A heated gaseous medium introduced into the sump region raises through the openings and heats the downward flowing wort to boiling temperature to degas and free the wort from undesirable foreign substances. Vapors from the wort are condensed in the head region and discharged, and the processed wort is discharged from the sump region.

Abstract: Utilisation of frequency divided OFDM (FD OFDM) in the uplink of a multi-access system requires that all mobile stations meet the requirements for orthogonality between sub-carriers in the time and frequency domain. Alternatively, another access technique can be used with OFDM, which can tolerate some relaxation in orthogonality requirements, e.g. code division OFDM (CD OFDM, or COFDM). The use of FD OFDM thus requires a random access technique that does not disturb the orthogonality between sub-carriers. Because time synchronisation is essential if orthogonality is to be preserved between sub-carriers, it is vital that delay difference between a mobile station and a base station be estimated during a random access protocol. In a random access protocol, a mobile station transmits a known signal sequence to a base station. The base station can lock onto the known sequence, detect it and estimate the time delay. According to the present invention, the random access sequence can be repeated cyclically and may comprise a m-sequence, a Gold sequence, or a four phase sequence with good cross-correlation properties, which is modulated onto the sub-carriers in the frequency domain. The random access sequence is transmitted without guard spaces. The random access sequence may be modulated onto all sub-carriers, or alternatively onto selected sub-carriers only. Alternatively, the random access sequence may be modulated onto all sub-carriers, but some sub-carriers may be transmitted at higher power than others. <IMAGE>
