Abstract: A method and a system for regulating the mixed air in a heating/air-conditioning unit (1) of a motor vehicle in which fresh air and/or recirculated air are fed to a heating/air-conditioning unit (1) which controls the feeding of fresh air and/or recirculated air in the passenger compartment of the vehicle. In a method for optimizing the consumption of energy for such heating/air-conditioning systems, the feed of fresh air and/or recirculated air is so adjusted that the temperature of the dew point of the air within the vehicle is less than the temperature on the inside of a window of the vehicle.
Abstract: Spherical head coupling for Bowden cables to establish a connection between actuator and control elements in automotive vehicles, wherein the Bowden cable is equipped with a terminal piece exhibiting a ball socket and the actuator or control element with a spherical cap held in the ball socket. The ball socket is formed by a spherical cap of a low height, i.e., a height that is less than the length of one half of the sphere diameter, wherein the spherical head is encompassed on its side facing away from the spherical cap by a counter support held on a laterally elastic bar extending parallel to the center plane of the spherical head. The spring elastic bar is offset in its location from the center plane in the direction of the insertion side of the spherical head and the counter support encompasses the spherical head on the opposite side.
Abstract: A process for the production and further processing of strands for Bowden cables of several wires stranded together by twisting, comprising dressing the strands after stranding between reversing rolls, subsequently stretching and again dressing between reversing rolls. Dressing is effected prior to stretching in several stages with decreasing bending radii and after the stretching again in several stages with increasing bending radii, while the stretching is performed with a force approximately within the area of the elastic limit, corresponding to 45% to 70%, preferably to 55% and 65% of the ultimate tensile strength of the strand.

Abstract: A rocker switch comprises a contact spring in the shape of a loop, supported against a pivot member. The spring has a catch in the free end of the loop. The contact spring can be pivoted by means of a rocker lever into its open or closed position. The rocker lever is mounted on a roll provided with two additional cams in the form of a rocker. By means of an elastic switching arm arranged on the slide, the rocker is actuated by overrunning, thereby effecting the pivoting of the end support cam over the pivot member. This in turn yields movement of the contact springs into their open or closed positions. The contact springs may be arranged in series adjacently to each other and/or on a common axis successively to each other with their loop openings in the same or in opposing directions.
Abstract: An actuation device for use with a linearly actuated control element. The actuation device comprises a take-up body, a housing enclosing the take-up body, a shaft extending outwardly of the housing for rotating the take-up body, a flexible tension and compression element secured at one end thereof to the take-up body and a tube member extending outwardly of the housing and enclosing at least a part of the tension and compression element. The tension and compression element comprises a flexible guide strand and a plurality of elongated, rounded compression bodies wherein each compression body is threaded onto the flexible guide strand and positioned closely adjacent one another to form a tight packing.

Abstract: An adjustable air outlet nozzle for automobile heating and venting systems in which a spherical hollow nozzle is connected to a surrounding housing lodgement by means of an intermediate gimbal ring and includes a double-clappet valve which is operable by means of a wing knob, through a bevel gear drive. The nozzle shell has an inner wall with an abutment shoulder for the valve clappets and a progressively widening gap for sensitive throttling of the air flow.
