Abstract: A circuit arrangement for charging batteries comprises a charging current source for supplying charging current pulse trains. The circuit arrangement comprises a first detection device for determining an actual voltage dependent upon a variable reference voltage, which actual voltage is proportional to the average sum voltage of a battery. The first detection device supplies a detection signal corresponding to the detection result and which controls the duty cycle of the pulse-shaped control signal which can be generated by a control pulse generator. The control pulse generator varies the duty cycle dependent on the detection signal when the actual voltage increases or the reference voltage decreases, in a manner such that the ratio between the charging period and the charging pause in a charging pulse train is reduced. A device is provided which enable the reference voltage to be varied in the same sense as the duty cycle depending on this duty cycle.

Date May 2, 1996The present invention relates to a milling cutting insert having an upper side, a bottom side, and flank surfaces connecting the upper and bottom sides. At each operative cutting corner there is a projection which is depressed relative to the adjacent main cutting edge and corner cutting edge. At the front upper edge of the projection is the wiper edge that generates the surface on the workpiece. By tipping the cutting insert axially positively and radially negatively, the horizontally located wiper edge may be tipped frontwards into contact with the workpiece, while the vertically located wiper edge is tipped backwardly, so that it does not reach the workpiece. In this way an improved axial clearance is made possible and an undesired groove in the workpiece is avoided, which would otherwise be caused by the vertically located wiper edge.

Abstract: Growth or metastasization of malignant tumors can be inhibited by administering to a patient in need thereof sufficient lactose to block crucial lectins on the affected organ so that the tumor cells cannot anchor to other locations in the body. Lactose can be administered alone, or in combination with conjugates of cytotoxic drugs. Preferably, lactose is conjugated to a cytotoxic substance so that the primary tumor is treated concurrently with prevention of metastasis. Additionally, by conjugating a cytotoxic drug to lactose, the cytotoxic drug is maintained in close proximity to the tumor because of the receptors on the tumor which bind the lactose (and therefore the cytotoxic agent bound thereto) to the tumor cells. By using a conjugate of lactose with a cytotoxic agent, one dose is generally sufficient to destroy the receptor sites on the tumor and prevent metastasis of the tumor while treating the tumor.

Abstract: A moldable panel having a predetermined shape for cushioning and protecting protrusions and areas including a flexible elastomeric thermoplastic honeycomb panel and a rigid thermoplastic plate. The honeycomb panel has a honeycomb core formed of undulated strips of resilient thermoplastic material, thermal compression bonded together to form cell walls defining a plurality of contiguous regularly shaped cells. The core has a first face formed by a first extremity of the cell walls and a second face formed by a second extremity of the cell walls. The core is maintained in its expanded configuration so that it can be used to anisotropically flex to stabilize and spread the load experienced by a user of the moldable panel. The core is bonded to a first surface of the rigid thermoplastic plate. The plate is heated to a first temperature which is sufficient to mold or form the plate into the desired shape, but insufficient to melt the bonds formed between the honeycomb panel and the plate, and the bonds between the strips of the honeycomb panel. The second face of the honeycomb panel is heated to a second temperature, lower than said first temperature, to relieve stresses built up in the panel as the plate is being molded.

Abstract: An E.coli strain which 'over-produces' L-tryptophan, comprises, in the genome thereof, a mutant gene which encodes partially-defective tryptophanyl-tRNA synthetase (preferably the trpS378 allele) - which when present in a non-producing strain, is characterized by a temperature-dependent tryptophan auxotrophy - and has a further mutation on the chromosome thereof in at least one gene selected from mtr (especially mtr - 24 ), aroP (especially aroP579 ), tnaA (especially tnaA1 ) and tnaB . The strains may be transformed with a plasmid which carries the tryptophan operon encoding an anthranilate synthase enzyme, freed from feedback inhibition by tryptophan, and/or which possess mutations in at least one gene selected from the trpEDCBA - group (which, when present in a non-producing cell, confers tryptophan auxotrophy thereon). L-tryptophan may be prepared by the cultivation of the said strains at ca. 30 degrees C (preferably in the presence of yeast extract), limiting growth by the concentration of available phosphate (in an appropriate medium), followed by fermentation (in the absence of yeast extract) at from 33 to 37 degrees C. The fermentation is preferably effected in the absence of antibiotics.
