Abstract: An apparatus for propulsion control in a motor vehicle with an anti-locking system is proposed, in which the supply and outflow of pressure medium is controllable via electromagnetically actuatable valves and which is characterized in that means are provided with which the return flow line can be exposed to pressure. It is the purpose of the apparatus to expand an anti-locking system to include a drive slippage regulating function, and this expansion is problem-free and cost-favorable. The proposed apparatus furthermore assures that a brake pedal actuation has priority. It is also proposed in the case of excessive slippage of both driven wheels to reduce the engine output. This is attained with a controllable drag member disposed between the driving pedal (or linkage) and the throttle valve, the control of the drag member being effected by means of the auxiliary pressure in the return flow line and via an electromagnetically controllable three-port, two-position valve for a hydraulic AND member.

Abstract: A control apparatus for internal combustion engines, which generates an adjustment path on the part of an adjustment member which is proportional to the air mass supplied to the engine. The control apparatus contains a counterpart pressure chamber sealed off from the outside and separated in a pressure-tight manner by an adjustment diaphragm from a first pressure chamber exposed to induced air pressure. A pressure source generating a reference absolute pressure which is constant under all operating conditions is connected to the counterpart pressure chamber. Consequently, the apparatus performs the function of a charge pressure stop equipped with a diaphragm box. The air reservoir of an air pressure brake system, a reservoir charged with the exhaust gas counterpressure or charge air pressure, or a vacuum pump can serve as the pressure source, and an absolute pressure controller controls the reference absolute pressure prevailing in the counterpart pressure chamber.

Abstract: An electromagnetically actuatable valve is proposed, which serves in particular to inject fuel into the intake tube of internal combustion engines operating with fuel injection systems. The fuel injection valve includes a valve housing, a shell-type core having a magnetic coil, and a flat armature. The flat armature is firmly connected with a spherical valve element which passes through a central guide opening in a guide diaphragm and cooperates with a fixed valve seat. The guide diaphragm guides the valve element in the radial direction toward the valve seat. The flat armature contacts the guide diaphragm via a concentric shoulder providing tension thereto so that the armature is guided in a plane parallel to the end face of the shell core. The fuel supply to the valve is effected via radial inlet openings in the valve wall.

Abstract: A fuel injection system for injecting fuel into the air intake tube of an internal combustion engine, including at least one fuel injection valve, which is disposed in a holder body and communicates with a fuel supply line and a fuel outflow line. The fuel injection valve is provided with a fuel supply groove, branching off from which are fuel inlet openings, and a fuel outflow groove, leading away from which are fuel outlet openings. The fuel injection valve is guided in the radial direction in a guide opening of the holder body by supporting bodies of a fuel filter which extends axially over the fuel injection valve, covering the fuel supply groove and the fuel outflow groove. The middle supporting body of the fuel filter is embodied such that it seals off the fuel supply line and the fuel supply groove from the fuel outflow line and the fuel outflow groove.

Abstract: An apparatus is proposed which serves to form the operating mixture for internal combustion engines, in particular for mixture-compressing engines having externally supplied ignition. The apparatus includes an air measuring device having a control body, which has a circularly curved control section and an actuation section.

At least two electric heating elements are mounted opposite to each other on the same horizontal level in the body at both ends thereof and the body has a water outlet and a water inlet centrally located, respectively, in the top and bottom thereof. Two identical T-shaped nozzles are mounted in a symmetrical manner to the inlet and the outlet of the device, respectively, by a short vertical bar of the nozzle. Each nozzle includes elongated closed-end horizontal bar provided with two sets of holes symmetrical with respect to the vertical bar of the nozzle.

Abstract: A method and an apparatus are proposed for performing a comparison of patterns of invariable form, especially fingerprint pattern. By the application of a finger on a prism within a beam of light, a latent picture of fingerprint lines is obtained which is optically compared with a copy of the same fingerprint stored in memory or located on a card. After conversion into an electrical variable, an identification pulse results which is subjected to at least one test criterion and compared with a threshold value. Preferably the testing of a master symbol located on the inserted card is effected at the same time, comparing this with a copy of the same stored in memory within the appliance. If the test criteria show an agreement of the fingerprint with the fingerprint copy and/or of the master symbol with the copy of the master symbol then a positive assessment is effected, and access to a building, for instance, is furnished.

Abstract: A fuel injection nozzle is proposed which opens toward the outside and functions with a valve needle and two springs, and further wherein a throttle restriction is effective after a first portion of the opening stroke, acting as a pre-stroke, and can be subsequently rendered ineffective. The two springs having a predetermined certain relationship to one another enable an abrupt increase in closing force after the pre-stroke. The first spring, embodied as a compression spring, acts in the closing direction; the second spring, having a smaller force than the first spring and acting counter to the closing direction, is rendered ineffective after the pre-stroke has been performed.

Abstract: There is proposed a hairstyling appliance which has a hair curler cylinder and a hot-air nozzle. The hair curler cylinder is provided with slits; its interior communicates with an air-aspirating device. The hot-air nozzle is directed toward the surface of the hair curler cylinder. Hot air generated by a dryer also provided in the appliance flows from this hot-air nozzle. Upon rotation, the hair curler cylinder takes up the hair and winds it up as a result of the underpressure prevailing at its slits. The hair is then held in the wound-up position, while it is subjected to the flow from the hot-air nozzle. The air, after absorbing water vapor upon passing through the hair, is simultaneously aspirated away from the interior of the hair curler cylinder. The hot-air nozzle is disposed on the appliance at a predetermined, fixed distance from the hair curler cylinder.
