Patent SE-8400768-D0 (SE)
Inventor: SCHREIBER P
IPC: B23K35/02

Abstract: An electric resistance seam welding method and apparatus includes a continuous wire electrode which is passed successively over a first electrode reel and thereafter over a second electrode reel via a plurality of guide and deflection rollers, the outer surfaces of the wire confronting each other when passing over the reels and being pressed together by the reels by a predetermined welding force against interposed workpieces to be seam welded together. An electric current is applied so as to pass from the second electrode reel to the first reel through the wire electrode and the interposed workpieces, and the wire electrode is motor driven for feeding the workpieces through the reels. A copper wire is utilized as the wire electrode and has a tensile strength at the elastic limit of between 11 and 13 kg-f/mm2 and has a percentage elongation at break of 26 to 17%. The reels are pressed together by a force of 60 to 70 kg, and the copper wire is subject to a tensile stress of less than 10 kg-f/mm2 while passing over and between the reels. The reels are maintained at an operating temperature of 10 DEG  to 30 DEG   C. as the wire electrode passes thereover, so that a maximum elongation of the wire of 6% when passing over the first reel, and a maximum further elongation of the wire of 6% when passing over the second reel, is attained.

Abstract: The present invention relates to a method and an arrangement for preventing unacceptable temperature variations in spaces 2 with electronic units 3, the components of which give off heat during operation and are sensitive to large and/or sudden temperature variations. In order to ensure accurate control of the cooling function without having to use a water cooler, cool night air is made to flow to the space 2 with the electronic unit 3 via a pipe system 6 in a cold magazine 5 consisting of a concrete material and located below or next to the building 1 in which the space 2 with the electronic unit 3 is situated. The cold stored in said cold magazine is released for cooling warmer air which is made to flow to the space 2 during the daytime, heat being carried away from the heat-emitting electronic components of the electronic unit 3 by outside air being guided from said cold magazine 5 into the space 2 and being made to flow upwards past these by being mixed with the heat rising from the same. The arrangement for implementing this method has an air supply device 7 which releases air at such a low level or such low levels in the space 2 that the air, by being mixed with the heat rising from the heat-emitting electronic components, is made to flow slowly upwards in the space. <IMAGE>

Abstract: The front part flow of asphalt is scraped away to form a lower layer (39) on the conveyor belt, and the rear part flow is scraped away to form an upper layer. Both layers are then mixed with each other for laying on the highway at the rear end of the machine. A funnel-shaped raisable and lowerable accessory is fitted on the fixed end wall (11) of the tray. The front end wall (27) of the accessory forms a separator for the front and rear part flows after filling. This front end wall has a lower edge forming a front scraper (33) which determines the thickness of the under layer (39) on the conveyor belt. Via an input aperture (16) in the rear end wall of the tray, the under layer of asphalt is fed with free height to a rear scraping edge (34). Asphalt is fed on to the under layer at the accessory end through the rear part flow, and scraped away by the rear scraping edge to form an upper layer (40) on that beneath it.

Abstract: A process for speech analysis and more specifically an automatic process for the analysis of continuous speech. The waveshape of the speech is described with the aid of the resonant frequencies, formants, which arise in the speech organ. The process determines suitable frequencies for the formants from an utterance by dividing the utterance into time frames and analyzing the utterance by linear prediction in order to determine roots of the denominator polynomial and thereby frequency values for each frame. The utterance is divided into voiced regions and in each voiced region the centers of vowel sounds are established in order to obtain a number of starting points. Tracks are formed from the starting points by sorting the roots from frame to frame so that old and new roots are linked together. Factors of merit are calculated for the tracks relative to formants and the tracks are distributed to formants in accordance with the factors of merit. The factors of merit take into consideration the bandwidth, continuity and relation to the formants of the tracks. The process gives a global optimisation by delaying the formant allocation until a complete voiced region has been analyzed. By linking the tracks together in this way, additional/false resonances can be controlled, which resonances arise in association with linear prediction.

Abstract: Apparatus for automatical bringing of soft, flimsy, flat articles from an undefined position to a known position. Before mechanical folding of articles such as towels and sheets the article has to be brought into a correct position from an in general undefined. An undefined position arises for instance after drying of laundry when the articles may fall unguided. The articles are from here handled manually as it has shown difficult to automate. The invention solves this problem. The apparatus consists of horizontal bars (2) with clamps (3, 4) for bringing the article along. The bars are moved by a conveyor (5) stepwise to fixed positions from a starting position to an endposition at the same time as tip (B, C and D or E) is sought, gripped and moved to the clamp in question by a front searching device (10), a middle searching device (11) and a rear searching device (12). For gripping and moving of the article in the beginning a loading device (9) is used. The clamps are activated and positioned along the bars by activators (6). In the endposition the article is hanging by two chosen corners in a known position.
