Abstract: Bei einem Verfahren zum Durchführen eines Heißstarts bei einer Brennkraftmaschine wird eine Heißstartbedingung aus der Kühlwassertemperatur und der Ansauglufttemperatur erkannt. Eine Heißstartkennung wird abgespeichert, wenn während einer Nachbetriebszeit (TN) nach Abstellen der Brennkraftmaschine die Kühlwassertemperatur und die Ansauglufttemperatur beide mindestens einmal jeweils einen zugeordneten Grenzwert (GKW1, GAL) erreicht haben. Beim nächsten Start der Brennkraftmaschine wird dann der Heißstart durchgeführt, wenn die Heißstartkennung gespeichert ist und die Kühlwassertemperatur noch über einem zweiten Grenzwert (GKW2) liegt. Das Verfahren stützt sich also nur auf bei Motorsteuergeräten sowieso vorhandene Temperaturgeber und braucht insbesondere keinen zusätzlichen Temperaturgeber zum Messen der Temperatur des Kraftstoffs.

Abstract: In an accumulator cell, ring flanges (9, 11) are integrally formed on the plastic sleeve (8) arranged between the terminal shaft (3) and the tubular cover opening (1), which ring flanges (9, 11), on the basis of their profile shape, on the one hand take over the function of O-rings at the relevant supporting points on the terminal shoulders 4, 5 and, on the other hand, increase the cell's immunity to electrolyte running out by additional sealing surfaces (10, 12) on the lower end edge of the cover tube and on the upper terminal shoulder 5. The sleeve can be injection moulded directly onto the inner wall of the cover tube or is plugged onto the terminal as an individually moulded component. Publication with the Figure. <IMAGE>

Abstract: Cryptographic methods and apparatus for forming, checking, blinding, and unblinding of undeniable signatures are disclosed. The validity of such signatures is based on public keys and they are formed by a signed party with access to a corresponding private key, much as with public key digital signatures. A difference is that whereas public key digital signatures can be checked by anyone using the corresponding public key, the validity of undeniable signatures is in general checked by a protocol conducted between a checking party and the signing party. During such a protocol, the signing party may improperly try to deny the validity of a valid signature, but the checking party will be able to detect this with substantially high probability. In case the signing party is not improperly performing the protocol, the checking party is further able to determine with high probability wether or not the signature validly corresponds to the intended message and public key. Blinding can be used while obtaining undeniable signatures, while providing them to other parties, and while checking their validity.

Abstract: Multifrequency modem in which the serial bit string received from the DTE (10) is divided into groups of bits the number m of which is determined by the characteristics of a sub-channel of the passband of a telephone line (22). A convolutional coding means delivers m+1 bits in response to the m bits of each group, these m+1 bits being converted into a complex symbol of a constellation with 2<m+1> points, the inverse discrete Fourier transform then being performed (16) on the sequence of symbols X(k) so as to obtain a sequence of digital samples over time (18) to be transmitted over the telephone line after conversion to analog signals. On reception, the sequence of digital samples over time (26) is transformed into a sequence of complex symbols (30) by a discrete Fourier transform (28), a Viterbi algorithm weighted as a function of the relevant constellation then being applied (32) to the symbols so as to obtain the data bits. <IMAGE>

Abstract: This invention relates to an enzyme assay of biological substances utilizing hydrogen peroxide as the reaction product in a NAD(P)-NAD(P)H system, which comprises first adding isocitric acid, metallic ions and isocitric acid dehydrogenase to a specimen to thereby consume intrinsic substances inhibiting the assay and at the same time reproduce decreased NAD(P)H, then adding a chelating agent thereto to deactivate the isocitric acid dehydrogenase, further adding simultaneously or thereafter an enzyme or a substrate capable of producing hydrogen peroxide as a reaction product thereto, and measuring produced hydrogen peroxide. Since the intrinsic substances which inhibit the assay are removed, the assay of the present invention enables the biological substances to be accurately determined based on the measurement of the produced hydrogen peroxide without being affected by said intrinsic substances.

Abstract: The invention relates to a packaging which consists at least in the region of an opening (12) of two foil layers, which have on their surfaces lying against each other a sealable and peelable coating. To tightly seal the opening (12), the foil layers are joined with one another by means of a heat-sealed seam (14) running essentially transversally to the opening direction (16). For the formation of flaps (18) which enable manual opening of the sealed seams (14), this sealed seam (14) is produced in such a way that it lies at a distance from the free opening edges (20) of the foil layers. For easy separating of the sealed seam (14) by pulling apart the flaps (18) in the opening direction (16), the sealed seam (14) runs from at least one section (22) lying nearer the opening edges (20) away to both sides at an angle to the opening edges (20). The sealed seam (14) can consist of various concrete forms; for example, it can be formed solely V-shaped or sectionwise V-shaped or also have the form of a curve, or comprise several curve-shaped sections.

Abstract: The conveying surface of the endless transport belt of the conveying device is made up of slats (32) arranged in a row. They are formed by sheet-metal blanks and are supported on link chains (G). In addition, the slats (32) can be manually detached from the transport belt or fitted into it. The link chains (G) at the edges mesh with the return wheels designed as sprockets (3). At the same time as providing good conditions for efficient mass production, this provides the possibility of also transferring very hot mouldings of plastics with aggressive and/or abrasive characteristics. In the event of soiling which could impair its function, or in the event of defects, individual components can be exchanged in a way involving little work and easy handling (Fig. 4).

Abstract: A slurry pumping method and an apparatus (2) to deliver slurry waste from factories to a filter press (5) for solid-liquid separation. In this apparatus, a pair of laterally or vertically arranged diaphragm type pumping devices (2) are activated by hydrau­lic cylinders, each consisting of a main cylinder (17) and a sub-­cylinder (19) directly connected to the main cylinder, to introduce slurry (26) from the slurry tank (4) and deliver it under pressure by a resilient diaphragm (12) of each pumping device to the filter press (5) where it is processed for solid-liquid separation. One of the diaphragm type pumping devices is first started, followed by the other, thus alternately and repetitively activating the two pump­ing devices to achieve continuous operation of the slurry pumping process. When the processing is completed, the two hydraulic cylinders of both diaphragm type pumping devices are stopped by controlling the sleeve valves (33, 34). In this way, an effective slurry pumping can be achieved.
