Abstract: In the case of a control system for an at least temporarily four-wheel-driven motor vehicle having an electronic control unit, which determines at least the rotational speeds of all wheels and the vehicle speed, and by which the driving torque of a drive unit can be distributed in a variable manner by way of a controllable transfer clutch to primary driving wheels, which are permanently connected with the drive unit, and to secondary driving wheels which, can be connected with the drive unit as required, the control unit closes the transfer clutch when the slip of a rear wheel exceeds the slip of the front wheel of the same vehicle side by a value which is greater than a given first threshold and when, preferably, also the longitudinal deceleration of the vehicle exceeds a given second threshold or the lateral acceleration of the vehicle exceeds a given third threshold.

Abstract: A cryostat configuration comprising an outer shell and a cryocontainer (2) for cryogenic fluid installed therein, wherein the cryocontainer (2) is connected to the outer shell via at least two suspension tubes (16), and with a neck tube (1) whose upper warm end is connected to the outer shell and whose lower cold end is connected to the cryocontainer (2) and into which a cold head (3) of a multi-stage cryocooler is installed, wherein the outer shell, the cryocontainer (2), the suspension tubes (16) and the neck tube (1) delimit an evacuated space, and wherein the cryocontainer (2) is moreover surrounded by at least one radiation shield which is connected to the suspension tubes (16) and optionally to the neck tube (1) of the cryocontainer (2) in a thermally conducting fashion, is characterized by a seal which can be manually and/or automatically actuated to separate the cold end of the neck tube (1) from the cryocontainer (2) in such a manner that fluid flow between the cryocontainer (2) and the neck tube (1)

Abstract: The invention relates to a method for producing a component, comprising a body (1), to which pressure-sensitive adhesive is applied, at least in sections. To produce the component (10, 20, 30), a pressure-sensitive adhesive base (6) is applied to the body (1). Said applied pressure-adhesive base (6) is at least partially cross-linked until it achieves a predetermined viscosity. The pressure-sensitive adhesive base (6) is preferably applied directly to the body (1). The component is cost-effective to produce, can be simply mounted and is extremely strong.

Abstract: A cannula for puncturing blood vessels comprising a beveled cannula tip and a cannula holder wherein the cannula is fixedly mounted, the cannula holder having at its rear end a flexible tube and being at least partially surrounded by a wing-shaped handle and a protector cap covering the cannula tip, wherein the protector cap and the handle are formed as a unit, which is slipped onto the said holder from the cannula tip, the said cannula holder comprises a locking collar and the said handle comprises a snap-in groove whereby said locking collar is locked in said snap-in groove when the unit is mounted on the cannula holder and the said cannula holder is provided with a shoulder facing said tube at a distance from said handle.

Abstract: A digital control loop is provided in which analog signals supplied by a tachometer, driven by an electric motor, are digitally evaluated, that is are compared with a reference value existing in digital form, and a deviation from the reference is employed for controlling the adjustment of an element, a thyristor preferably a triac, by way of an adjusting value generator which is likewise designed as a digital circuit. The speed control regulator can be designed both with an integral control behavior, and a differential control behavior, as well as being designed with a proportional control behavior and combinations thereof.
