Patent SE-0100436-L (SE)
Inventor: VAAGSTEDT NILS-GUNNAR
IPC: G01F17/00
Filed: 2001-02-12
Abstract: The present invention provides a method and system for determining the volume capacity of a fuel tank (FT) of a vehicle which has a fuel level sensor (FS) situated in the fuel tank (FT). A number (n) of known possible values (   VI, VII, ...., Vn    ) for the volume capacity are stored. The quantity of fuel (   Vc1   ) consumed between a full refu elling of the vehicle and a subsequent refuelling of it is determined. The ratio between the residual quantity of fuel and the full quantity of fuel at the beginning of said subsequent refuelling is determined. A value (   V1   ) for the aggregate v olume capacity of the fuel tank is calculated on the basis of the quantity of fuel consumed between the two said refuellings and said ratio. An assumption is made on the basis of the calculated value (   V1   ) as to which of the known possible valu es (   VI, VII, ...., Vn   ) corresponds to the a ggregate volume capacity of the fuel tank. The method is repeated on the occasion of subsequent refuellings, and new improved assumptions about the volume capacity are made on the basis of further calculated values of it.

Abstract: The method is for cooking of cellulose pulp in which the raw material, preferably in the form of chips, undergoes a successive elevation of temperature towards the cooking temperature while the chips are first impregnated with an impregnation liquor followed by cooking in a cooking liquor that is preferably alkali. Through the addition of pre-evaporated black liquor, either as early as the impregnation stage or during the subsequent cooking stage, an improved delignification process is achieved in which the pulp obtains improved properties, primarily with respect to strength/viscosity for a given degree of delignification, and also with respect to yield. The method can be used both for continuous cooking and for batch cooking of cellulose pulp.

Abstract: Welding arc stabilizing and igniting is effected with at least one pulse-forming condenser switched by spark gap or semiconductor switch to deliver a sharp discharge pulse through the winding of a pulse transformer, the magnetic energy thus built up in the transformer being then dissipated by a unidirectional diode bypass of the winding through the switch. The pulses are delivered by the transformer to the welding electrodes, and can be combined with pulses of lower voltage and longer duration by an appropriate series condenser-resistor combination in the transformer output. The pulse-forming condenser can be charged by simple resistor connection to the input of a step-down welding current transformer, or by transformer coupling to any source of AC welding current. Trigger means can also be connected as by transformer coupling for operation from the welding current to trigger the pulse discharge switching at the appropriate times in the current waves, although the triggering can be effected through the use of voltage-dependent pulse switching and the charging of the pulse forming condensers to voltages at least as high as that needed to actuate the switching. The switching means can also be protected by a blocking condenser in series in the output of a pulse-forming condenser, and the blocking condenser can be bridged by a resistor to bleed off the charge developed in the blocking condenser by a discharge pulse.

Abstract: A garment intended to be worn closest to the skin during vigorous physical activities in warm environments. The garment comprises a comparatively open warp knit fabric into the base of which are bound vertically extending cords. The warp knit fabric base is a mesh fabric consisting of thermo-settable synthetic fibres and is set to retain its shape, whereby it forces the cords to be displaced in parallel laterally upon movements, the cords being in contact with the skin. On account of its rigidity, the fabric provides an improved pumping effect upon relative movements between the garment and the body, thus improving the ventilation and carrying away of perspiration from the body. The garment has sufficient width to ensure that it is allowed to move unimpededly over the skin surface of the wearer.

Abstract: Method and arrangement for transmission of digital information, where the encryption and decryption is done by means of a so-called external key in the form of a bit sequence of random characters, which is transmitted after the transmission of the encrypted information. According to the invention, there are current switch elements S1, S2, S3, S1r, S2r, by means of which a time reference pattern from a time reference signal generator SG is repeatedly transmitted from the transmitter T to the receiver R and a new external key is transmitted in conjunction with each such time reference pattern, which is identified by means of said pattern. Preferably, a sequence p1-p16 of the transmitted bit stream is selected as new external key for a subsequent time interval B2 and this selected external key can be transmitted several times multiplexed into the bit stream. The selected and transmitted external keys are entered into the encryption generator KG both at the transmitter end and the receiver end at a time t01, t12 dictated by said reference time pattern. Thus, the same external key will only be used for a brief time, namely, the time required for selection and transmission of a new external key with corresponding identification time reference pattern, which makes illicit decryption difficult. If the transmission is disrupted so that the synchronisation is lost, the system will automatically resynchronise itself by transmission of the next time reference pattern and corresponding new external key after the disturbance. The invention can be used in voice encryption equipment. <IMAGE>
