Abstract: What is proposed is an electrical energy generator that uses air pressure from a pressurized source for breathing purposes in an underwater or smoke environment wherein a conduit passes the air pressure to a turbine generator that operates at high speed in response to the flow rate of the pressure drop therethrough for generating an electrical output while the user of the device breathes through a mouthpiece connected via conduit to the generator.
Abstract: A sterilizing apparatus for packaging containers is equipped with a closable preparation apparatus for a mixture of hot air and sterilizing agent vapor and a sterilizing chamber, into which containers to be sterilized are introduced. The closure means for the sterilizing chamber includes means for suspending a container to be sterilized within the sterilizing chamber. In order to realize a reduced use of sterilizing agent and heating energy, the apparatus has a circulatory system of mixture supply. The sterilizing chamber, as well as a bypass parallel to it, forms a part of this circulatory system. The bypass and the sterilizing chamber are alternately connected with the circulatory system by means of a reversing valve during nonsterilizing and sterilizing periods. A circulating blower, an air heater, and a preparation apparatus are also part of the circulatory system.
Abstract: A pressure control valve with an impact plate which serves as a regulator for a specific drop in pressure. The pressure control valve includes an armature disposed in an electromagnetic field established by an electromagnetic coil and a permanent magnetic field, with the armature being rotatably supported between two respective pole shoes located on each side of the armature. The pole shoes located on one side of the armature, in contrast to the pole shoes located on the other side, have an opposing magnetic polarity induced by the permanent magnet. The pole shoes which are not aligned opposite one another on armature 85, are approached by armature 85 with movement of the impact plate toward a valve seat, and causes an increase in the air gap planes facing the armature, as compared to the other two pole shoes, and thereby establishes a non-linear characteristic for the pressure control valve.
Abstract: A piston member is mounted in a cylinder body to be axially movable and unrotatable relative thereto. A ball nut retaining balls is fixed to the piston member, and a screw shaft having a helical groove in engagement with the balls is mounted to be rotatable and axially immovable relative to the cylinder body. The screw shaft makes many rotations when the piston under fluid pressure slightly advances axially inside the cylinder.

Abstract: A fuel injection nozzle for internal combustion engines having an inwardly opening valve needle is proposed, this valve needle has a channel comprising two parts, the first of which located in the upstream direction, has a smaller measurement in cross section in one dimension than the diameter of the communicating or downstream part which has the exact injection diameter. As a result, the entry of shavings into the downstream part and the consequent alteration in injection are avoided.
Abstract: An electronically controlled fuel metering system for an internal combustion engine is proposed which includes devices for damping engine jerking. The following signals are formed: ti (k) as the up-to-date load value; tiM as the up-to-date averaged load value; ti (k-1)+.DELTA.ti/2 as a special load value for use in a transition into overrunning; and tiM+.DELTA.tiM/2 for the purpose of successive approximation of the average value to up-to-date load values in the case of slow acceleration processes and flat courses of load reduction. A computer-controlled realization is possible for forming and selecting the individual values. A block circuit diagram is also provided for an electronically controlled fuel metering system made up of discrete modular elements.
Abstract: A speed governor of a fuel injection pump for internal combustion engines is proposed, having a governor lever for adjusting the fuel injection quantity and a governor spring assembly engaging the governor lever counter to which assembly an rpm-dependent force acts. To compensate for manufacturing tolerances in the governor spring assembly, it is proposed that the effective length of a prestressed governor spring in the governor spring assembly be effected by means of the rotation of a spring plate, in that the spring plate has a sleeve provided with an outer thread, onto which part the governor spring can be threaded. After the rotation of the spring plate, this plate is held in its terminal position, under the influence of the initial stressing force of the governor spring, in a positively engaged connection with intermeshed components which limit the relieving of the governor spring assembly in the other direction.
Abstract: A cross slide contour form milling box tool which can be applied to automatic screw machines for contour form milling desired contours on the outside of a workpiece. The contour milling tool is positioned to a transverse slide to the drive axis. The transverse slide is driven by a pin and cam groove in the face of a cam so that the contour form milling tool is positioned in accordance with the shape of the cam groove. The milling cutter is positioned in the transverse slide and rotated by an auxiliary shaft which is driven by gears from the cam shaft using an Oldham coupling to rotate while reciprocating. The workpiece is rotated relative to the contour milling tour and the desired contour is form milled on the surface of the workpiece.
Abstract: A control apparatus for internal combustion engines, which generates an adjustment path on the path 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: A knocked-down easily-assembled sterilizing rack for holding conventional disk-shaped lids used for sealing mason jars. A sheet-metal inverted-trough-shaped body has a plurality of parallel transaxial slots to hold the lids upright and spaced. An initially unattached bail-shaped handle is dimensioned to embrace the sides and an end of the body for parts-protecting and for economical compact shipping-packaging. The handle and the body have snap-together assembling detent elements.
Abstract: A heating device for use in motor vehicles to rapidly heat combustion chambers, exhaust gas sensors, catalyzers and other associated apparatus. A resistive heating element is connected in series with a low-impedance measuring resistor and a switch across a power source, while a resistance bridge is formed with the aid of two further resistors. The diagonal bridge voltages are compared in a comparator whose output actuates a control circuit which operates the heater switch. The heater switch also provides the power for the comparator. In a first interval, constant current is applied to the heating element, while the current is pulsed during a second time interval. The switch control pulses may be provided by a free-running oscillator or one whose pulses are synchronized with the undulations of the engine starter current.
Abstract: An adjusting device for precise rotary angle adjustment of final control elements in closed- or open-loop control devices. The adjusting device comprises a rotary magnet apparatus in which parallel air gaps are formed between the poles of the armature and the magnet poles of the armature counterpart. In order to attain constant torques over the angle of rotation of the armature, when the electric current applied to the coil is constant, the end faces of the armature poles are embodied as wedge-shaped.

Abstract: An electromagnetically actuatable valve is proposed which serves in particular to inject fuel into the intake tube of internal combustion engine operating with fuel injection systems. The fuel injection valve includes a valve housing, a shell core having a magnetic coil and a flat armature, which is positively connected to a valve element comprising a ball which protrudes through a central opening in a guide diaphragm to cooperate with a fixed valve seat. The guide diaphragm guides the ball in the radial direction relative to the valve seat. Under spring tension, the flat armature, having a guide crown, contacts the guide diaphragm and is thus guided in a plane parallel to the end face of the shell core. A first fuel fitting comprises a portion of a valve housing preshaped by a non-cutting manufacturing method; a second fuel fitting is fixed inside the first fuel fitting in such a manner that a flow conduit is defined between the first and the second fuel fittings.

Abstract: A fuel injection pump which has an adjusting piston for the purpose of injection instant adjustment. The adjusting piston has opposite ends defining respective work chambers. The work chambers are supplied with fuel under rpm-dependent pressure from a suction chamber of the fuel injection pump, via respective throttles, and are relieved via respective outflow lines. The outflow cross sections of the outflow lines are controlled in complementary fashion by a control slide of a control valve. The control slide is exposed to a modifiable control pressure derived from the rpm-dependent pressure, and for the peripheral conditions of a cold engine and rpm of the engine below a threshold rpm, the maximum controlled pressure is established by means of a third control valve.
