Abstract: The present invention discloses a novel method for the production of a properly folded, functional insect- specific insect toxin protein in eucaryotic cells. The expression of the functional protein is achieved by the fusion of the DNA sequence encoding the structural gene product to a heterologous mammalian signal peptide. In the preferred embodiment of the invention described herein, the DNA sequence encoding the insect toxin of the scorpion Androctonus australis is joined directly to the DNA sequence encoding the human interleukin-2 signal peptide. This hybrid gene is incorporated into a eucaryotic cloning vector incorporating a selectable marker. Colonies of transformed cells identified via the selectable marker were subcultured and the culture media assayed for insecticidal activity. The resultant secreted protein demonstrated insecticidal activity against Aedes aegypti mosquito instar larvae while demonstrating no toxic effects in mice.

Abstract: The invention proposes a method of weighing, in which, by means of measuring points, which are each formed from at least two force sensors (1, 2) arranged in series and which are assigned to a load-receiving part, the load is determined by the addition of the measurement signals from the force sensors (1, 2). Provision is made for ensuring that, in succession, virtually any portion of the load-receiving part is first subjected to a known load and the influence of the location of introduction of force on the signals of the force sensors (1, 2) is determined, that correcting factors are assigned to the location points, that the location of introduction of force is determined by an association and evaluation of the measurement signals from the force sensors (1, 2) during the weighing operation, and that the measurement value of the measuring point is corrected by means of the aforesaid correcting factors. <IMAGE>

Abstract: A facility for making dynamic changes to a system master key without stopping the system, and without loss of integrity to ongoing cryptographic operations. A version number is generated and associated with the current master key. A dynamic change is made to the master key, resulting in the then current master key becoming the old master key, and a "new" current master key (with a new version number) being placed into operation. Subsequent cryptographic requests using a supplied key enciphered under the old master key are identified by means of a supplied version number associated with the supplied key. This identification triggers a reencipher operation, reenciphering the supplied key under the now current master key - after which the cryptographic operation proceeds. Unique patterns are generated to verify the contents of the master key registers, and to authorize normal use of the cryptographic facility, and issuers of key-change operations.

Abstract: The steam conversion valve (VU1) with spindle drive for a main and an auxiliary valve has a main valve (V1) with a main restrictor (6) for controlling the main steam flow (f11), the thrust forces of a spindle drive being transmissible to the main restrictor (6) by an associated main spindle (5) in order to open and close the main valve (V1). The steam conversion valve (VU1) furthermore has an auxiliary valve (V2) with an auxiliary restrictor (10a) for controlling an atomiser steam flow, the thrust forces of the spindle drive being transmissible to the auxiliary restrictor (10a) by an associated auxiliary spindle (50) in order to open and close the auxiliary valve (V2). The actuating forces of the common spindle drive (1) for the main spindle (5) and the auxiliary spindle (50) can in each case be transmitted to the main and auxiliary restrictor (6, 10a), respectively, via first and second resilient couplings (FK1, FK2), the two spindles (5, 50) being matched to one another in such a way that, during the closing operation, the main restrictor (6) closes before the auxiliary restrictor (10a) reaches its auxiliary valve seat (16), with the result that the main steam flow (f11) is shut off before the atomiser steam flow (f12) and that, during the opening operation, the auxiliary restrictor (10a) opens its auxiliary valve (V2) before the main restrictor (6) leaves its main valve seat (7), with the result that the atomiser steam flow (f12) forms before the main steam flow (f11).

Abstract: An estimated vehicle speed detection apparatus for motorcycles calculates an estimated vehicle speed based on a front wheel speed (VFRN) and a rear wheel speed (VRER) and applies antilock brake control to each of front and rear wheels (FW, RW) based on a calculated estimated vehicle speed. The apparatus includes a memory (VMEM) for storing the estimated vehicle speed at the time an application of antilock brake control to either the front or rear wheel (FW, RW) is started, or an application of brakes to either the front or rear wheel (FW, RW) starts. The apparatus further includes a calculation unit (CAL) for comparing the front wheel speed (VFRN) and the rear wheel speed (VRER) to calculate the estimated vehicle speed based on the higher of the front wheel speed (VFRN) or the rear wheel speed (VRER), while antilock brake control is applied to the front or rear wheel (FW, RW) or either a front brake or a rear brake is applied. In this case, the rear wheel speed (VRER) does not exceed the estimated vehicle speed previously stored in the memory (VMEM).

Abstract: Moderate pressure, (175-625 kPa) nitrogen is generated with enhanced nitrogen product purity and greater recovery of both nitrogen and argon in a cryogenic process for the separation of air using an integrated multi-column distillation system by effecting a high boil-up rate in the bottom of the lower pressure column, thereby creating a reduced liquid flow/vapor flow ratio (L/V), and utilizing a higher than customary nitrogen reflux to the top of the lower pressure column. The nitrogen reflux ratio is greater than 0.5 and the nitrogen concentration in the reflux is at least 99.5% by volume. Refrigeration to drive the system can be obtained by recovering the energy from the waste nitrogen stream and oxygen vapor from the lower pressure column. Refrigeration also can be obtained by withdrawing oxygen as a bottoms liquid from the lower pressure column, expanding that liquid to a lower pressure and using it to condense the nitrogen vapor generated in a higher pressure column which has been expanded in a turbo-expander.
