Abstract:
An apparatus for regulating the coolant circuit for an internal combustion engine is equipped with a radiator and a heating system heat exchanger, a water pump, and a thermostat valve which makes possible two circuits in the warmup phase of the engine or at low engine temperatures, one circuit being provided for cooling the engine via a bypass line, and a second circuit being provided to the heating system heat exchanger via a heating system line. A differential pressure valve, regulated as a function of engine speed, is arranged in the bypass line, the bypass line being blocked, and all of the coolant being passed through the heating system line, in the warmup phase or in the phase with a low engine temperature when the speed of the engine is low; and the differential pressure valve opening and uncovering the bypass line at higher engine speeds, a quantitative distribution of the coolant occurring via the bypass line and the heating system line as a function of the design of the differential pressure valve.
Abstract:
An automatic soldering installation includes a soldering head (10) which is composed of a connecting element (11), a soldering wire dispenser (12), focusing optics (13), and an actuator (24). The soldering head (10) is mounted on the arm of a robot (16) which allows to position it in such a manner that the soldering wire (14) is positioned in the area of a respective soldering point (19). The focusing optics (13) is connected to a laser (21) by an optical fiber (22) and operates to focus the free laser beam (15) on the soldering point (19). The actuator (24), which is controlled by a control system (25), allows to vary the distance between the focusing optics (13) and the soldering point (19) independently from the robot (16), and thus to vary the width of the laser beam (15) at the soldering point (19). A more uniform temperature distribution on soldering points (19) of different sizes is thus obtained. The control systems (17, 23, 25) of the robot (16), of the laser (23), and of the actuator (24), respectively, cooperate in order to supply an optimal amount of energy for each soldering operation in every case.

Abstract:
The present invention is directed to a resilient force clamping connection (2) for a terminal block (1), in particular a connection terminal or connecting terminal, so as to electrically connect at least one conductor, said resilient force clamping element comprising a busbar (3), and a clamping spring (4) having a support limb (40), a resilient bend (41) that adjoins the support limb (40), and a clamping limb (42) that adjoins the resilient bend (41), wherein the clamping limb (42) comprises at a free end (420) that is remote from the resilient bend (41) a clamping section (421) so as to form a conductor clamping site (K) between the clamping section (421) and the busbar (3) so as to electrically connect a conductor (L) to the resilient force clamping connection (2). At least one actuating limb (43) extends from the clamping limb (42) between the resilient bend (41) and the free end (420) in a direction away from the support limb (40), wherein the actuating limb (43) comprises an actuating section (430) in order to cooperate with a release element (5) so as to open the conductor clamping site (K). The present invention is further directed to a terminal block (1) so as to electrically connect at least one conductor, said terminal block comprising an insulated housing (6) and at least one resilient force clamping connection (2) according to the present invention and being received at least in part by the insulated housing (6).

Abstract:
A method for removing acid gases from a fluid stream comprises a) treating the fluid stream in an absorption zone with an absorption medium which comprises an aqueous solution of at least one amine, conducting the treated fluid stream through at least two scrubbing zones and treating it with a non-acidic aqueous phase in order to transfer entrained amine and/or entrained amine decomposition products at least in part to the aqueous phase, wherein aqueous phase is recycled via at least one scrubbing zone and aqueous phase is conducted through at least one scrubbing zone without recycling. The method permits efficient retention of amines from the treated fluid streams.
