摘要:
A device for camshaft adjustment in an internal combustion engine which has an inner rotor rotationally fixed to a camshaft. The inner rotor is rotationally adjustable relative to an outer rotor that is driveably connected to a crankshaft. At least one hydraulic chamber limited by side walls is introduced into the outer rotor and is divided into two partial chambers by an element extending radially outward from the inner rotor. To lock relative movement between the inner and outer rotor, two locking pins penetrating the inner rotor axially engage in two recesses of one of the side walls designed as a locking cover. To adjust the play of the locking pins in the recesses, at least one of the recesses has a stop surface for the locking pin, the position of which changes as viewed circumferentially with the radial distance from the axis of the inner rotor.

An optical measuring system includes at least one radiation source, at least one radiation receiver, and at least one flow through cell. The radiation emitted by the at least one radiation source passes at least partially in an optical path between the radiation source and the radiation receiver through the flow through cell and then strikes the at least one radiation receiver. The radiation receiver is embodied to output a signal dependent on the intensity of the radiation striking the radiation receiver, wherein the flow through cell is arranged in a cell holder, which is connected via a first connection interface releasably with the radiation receiver and which is connected via a second connection interface releasably with the radiation source.

A fibrillation-resistant insulin analogue may be a single-chain insulin analogue or a physiologically acceptable salt thereof, containing an insulin A chain sequence or an analogue thereof and an insulin B chain sequence or an analogue thereof connected by a polypeptide of 4-10 amino acids. The fibrillation-resistant insulin analogue preferably displays less than 1 percent fibrillation with incubation at 37° C. for at least 21 days. A single-chain insulin analogue displays greater in vitro insulin receptor binding than normal insulin while displaying less than or equal binding to IGFR than normal insulin. The fibrillation-resistant insulin may be used to treat a patient using an implantable or external insulin pump, due to its greater fibrillation resistance.

An insulin analogue comprises a B-chain polypeptide incorporating a chlorinated phenylalanine. The chlorinated phenylalanine may be located at position B24. The chlorinated phenylalanine may be para-monochloro-phenylalanine. The analogue may be of a mammalian insulin, such as human insulin. A nucleic acid encodes such an insulin analogue. The chlorinated insulin analogues retain significant activity. A method of treating a patient comprises administering a physiologically effective amount of the insulin analogue or a physiologically acceptable salt thereof to a patient. Chlorine substitution-based stabilization of insulin may reduce fibrillation and thereby enhance the treatment of diabetes mellitus in regions of the developing world lacking refrigeration.
摘要:
An electric hand-held power tool has a housing, a double-shelled handle attached axially to the housing, a selector ring pivotably located in the housing, and an actuating element supported by the selector ring and swivelable manually. The housing and the handle have a line connecting domes oriented parallel to an axis of the housing and located in a parting plane region between the housing and the handle for receiving connecting units. The connecting domes include centering elements for guiding and exactly positioning the handle shells when the handle shells are attached individually to the housing.

A timing adjustment device with axially joined components, clamped by a camshaft central screw on a hub element which maintains the required peripheral position of these components relative to one another within a narrow tolerance range. On a disk element of the timing adjustment device an insert section is formed, which can be inserted into a recess formed in the hub element and, in the region of the insert section, at least one anchoring structure is formed, through which the insert section is anchored on a counter-structure, which is provided by the hub element.

A control device of a blower and air conditioner module a for motor vehicle is disclosed with a blower controller and an air conditioner controller, which governs the refrigerating plant with a refrigerant condenser, as well as flaps and valves of the blower and air conditioner module, and processes information from sensors and a man-machine interface, with the blower controller and the air conditioner controller, together with a blower motor controller of a blower motor designed as a central control device and it is placed on the blower motor.
摘要:
The present invention relates to an exhaust manifold for an internal combustion engine, in particular in a motor vehicle, comprising a housing from which a plurality of inlet pipes emanate, which, in the built-in state, lead to cylinders of the internal combustion engine, and comprising a flange, which is welded to the inlet pipes and which, in the built-in state, is screwed to the cylinder head of the internal combustion engine by means of a screw connection. The fatigue strength of the exhaust manifold can be improved by subdividing the flange into at least two partial flanges in a longitudinal direction of the exhaust manifold.

An electric motor includes carbon brushes (5) disposed in a holder (6) that are pressed by means of a spring force (7) in a radial direction against a jacket face of a cylindrical collector (4) that is fixed to an armature shaft (2) of the motor. The holder (6) for the carbon brushes (5) can be removed from the motor with little effort as a result of a provision of covering means (11, 12) that cover a pivot bearing (3) of the armature shaft (2) to protect it against the entry of dirt on a side of the covering means (11, 12) facing the holder (6) for the carbon brushes (5), provided with one or more chamfers (14, 15) in such a way that the carbon brushes (5) slide over the covering means (11, 12) as the holder (6) is being pulled off and that the carbon brushes (5) thereby are thrust radially outward counter to the spring force (7).
