Abstract: A foldable wheelchair, which may be moved along a predetermined direction of movement, includes first and second side frames, drive wheels and travelling wheels rotatably supported on the side frames, and a folding mechanism which extends between the side frames, which can be moved between a folded position and an unfolded position, and which, in turn, includes first and second pivoting devices. Each pivoting device may be pivoted about a respective center axis, which extends approximately along the direction of movement, and each pivoting device has ends facing away from its respective center axis. Each side frame defines first and second pivot axes, which extend substantially parallel to the center axes. The ends of the first pivoting device are pivotable about corresponding of the first pivot axes, and the ends of the second pivoting device are pivotable about corresponding of the second pivot axes. The center axis of the first pivoting device, and the first pivot axes are substantially aligned in a first plane, and the center axis of the second pivoting device, and the second pivot axes are substantially aligned in a second plane, when the folding mechanism is in the unfolded position. The pivoting devices may be arrested in the unfolded position, thereby rigidly connecting the side frames to one another.

Abstract: A medical instrument comprises a main body having a path formed therethrough, through which a tubular member is insertable or drawable. A valve body is provided in the path of the main body, maintaining at least a liquid-tight state with the rod-like member, when the path is opened by the rod-like member inserted through the path, and closing the path at least in the liquid-tight state, when the rod-like member is not inserted through the path. The valve body has two end faces. The valve body is formed with a first slit openable in one of the end faces and a second slit openable in the other of the end faces. The first slit and the second slit cross each other in the valve body. In consequence, rod-like members being of widely varied outer diameters are inserted through the path of the main body and held therein in a liquid-tight state to thereby reliably prevent blood leakage. Also, blood flow-out when the rod-like member or members are abruptly withdrawn from the path of the main body is reliably prevented. Further, a single valve body is provided so that the construction of the medical instrument can be simplified.

Abstract: A novel fire alarm system with a plurality of smoke detectors which are adapted to be installed in different locations are connected through a data transmission line to a receiver where the smoke density signals transmitted from the respective smoke detectors and indicative of the density of smoke in the corresponding locations are processed for determination of fire presence. The receiver is provided with fire judging circuit which identifies the presence of fire only when the smoke density detected by any one of the smoke detectors exceeds a reference density level and when such smoke density lasts over a reference time period. Thus, the information from each smoke detector is analyzed with respect to the smoke density and the time period over which the smoke density of significant level lasts. Accordingly, a reliable detection of fire is effectuated. Also incorporated in the system is a selector by which said reference density level can be selected from a plurality of predetermined density levels of different values and by which the reference time period can be selected from a plurality of predetermined time periods of different values. Consequently, the criterion which is the combination of the smoke density and the related time period for determination of fire presence can be variably set depending upon the differing conditions of the locations under surveillance, enabling the system to be easily and successfully adapted for use in different fire monitoring conditions.

Abstract: The present invention concerns the measuring of a silicon coating on paper or cardboard moving in the form of a continuous web and which may as fillers contain substances containing silicon such as kaolin, or aluminum silicate. By x-ray radiation from a primary radiation source (3) and passing through the web is excited the characteristic x-ray radiation of an element, in a secondary radiation source (7) on the silicon coating side of the paper web (1), having a higher ordinal number than silicon (Si). The exciting radiation is sent obliquely against the surface of the paper or cardboard, whereby the irradiation of the surface is accentuated and the characteristic x-ray radiation of the silicon in the silicon coating can be excited. The exciting radiation also partly excites the silicon in the filler, but in this case it will be accompanied by the characteristic x-ray radiation of the metal associated with the silicate, such as aluminum in the instance of kaolin. These two fluorescence radiations are measured using a semiconductor detector (9) with good energy discriminating capacity, the quantity of silicon coating being calculable from the silicon energy peak recorded in the spectrum from this detector when it is corrected, as in the exemplary case, to eliminate with the aid of the aluminum peak the contribution of the filler and when in the scattered energy peak measured from the spectrum the irradiation correction is taken into account. If there is coating on both sides, two measuring heads are placed one after the other in the web's direction of travel by which the surface fluorescence is recorded from different sides.

Abstract: A typewriter or similar machine with a print wheel disposed on a shaft drivable by a motor, the characters of which are printed by means of a hammer. In accordance with the invention, use of a separate print magnet is to be omitted. This is made possible by the use of a lift-rotation motor. Its rotational movement is used for the rotational positioning of the print wheel, while the axial movement of the motor shaft is transferred to a print hammer pivotably disposed on the carriage. Determination of the engagement point of the motor shaft with the print hammer makes possible the optimum determination of the movement cycle of the print hammer as well as its print force. Thus the space above the motor for the print wheel, otherwise required for a print magnet, can be used for other purposes. Additionally there is a reduction of the masses which are required to be moved along the platen.

Abstract: In a method for purification of flue gases from a combustion installation the flue gases are first sucked from the installation and through a liquid, and are then pressed through a liquid, whereby the purified flue gases are fed out into the surroundings. During the transfer the flue gases are split up into as small units as possible in order to provide the best possible contact with the fluid. The method is carried out by means of a flue gas purifier (5) comprising a container (6), which contains a fluid, preferably water, and which is partitioned into chambers (18 - 24). One set of chambers (18 - 21) forms a suction compartment (A) and another set of chambers (22 - 24) forms a pressure compartment (B). Walls (12, 14, 16) forming partitions between the chambers force the flue gases to alternately pass through the fluid and above the fluid. A pump (26) sucks the flue gases through the suction compartment (A) and presses these through the pressure compartment (B). The walls (12, 14, 16) are at least partly provided with slits, through which the flue gases are made to pass thereby being subdivided into a plurality of flows, and the outlet (28) of the pump (26) ends in a spray nozzle immersed in the fluid. The first chamber (18) in the suction compartment (A) in the flow direction of the flue gases is provided with an inlet (25) for the flue gases from the installation, and the last chamber in the pressure compartment (B) is provided with an outlet (29) for purified flue gases. <IMAGE>

Abstract: The present invention relates to a method for direct sequence spreading of a data sequence (d(t)) or a modulated data sequence (s(t)). The method yields better spectral properties than conventional methods for data transmission using direct sequence spread spectrum (DSSS) and is also suitable for systems where one wants to conceal the existence of transmission, so-called stealth radio. This is achieved by one or more spreading sequence generators (21) in the transmitter and the corresponding sequence generators (31) in the receiver emitting new output data at a rate which essentially exceeds the one required for obtaining in the transmitter a certain desired spread bandwidth, the spreading sequence or spreading sequences (c(t)) being caused to bandspread the data sequence (d(t)) or the modulated data sequence (s(t)), and the desired spread bandwidth being obtained by filtering in band-limiting filters (22).
