Abstract: In a so-called starting aid for motor vehicles, synchronism in the rpm of the drive wheels during starting is provided by feeding a brake pressure derived from the rpm difference of the drive wheels into the wheel brake cylinder associated with the wheel having the higher rpm. To this end, one brake pressure controller having a control piston and a valve is installed in each brake line to the wheel brake cylinders of at least two wheel brakes. The control pistons are actuated in opposite directions via a final control element to which a control signal derived from the rpm difference is supplied. Upon displacement, whichever control piston is driven closes the valve and feeds brake pressure into the associated wheel brake cylinder. In order that the starting aid will have a high control speed and a small structural volume, the final control element is embodied as an electric control motor.

Abstract: A novel ventilating system (10) for human patients including nebulizing means (15A) for nebulizing a liquid medication into a supply (28A, 29A) of humidified breathable gas under pressure. The nebulizing means (15A) comprises a nebulizing module having a cap portion (25) to which is attached a vial-like nebulizing chamber (54A). In order to maintain the hermetic integrity of the system (10) a two-position, flow control valve assembly (64) is operatively connected to and in selective flow communication with, a lower region of the vial-like, liquid-retention nebulizing chamber (54A). The valve assembly (64) is configured so that it can be manually actuated between a first position precluding access to chamber (54A) or a second position for drainage of liquid (59A) from within the nebulizer chamber (54A) or addition of liquid to such chamber while maintaining system sealing and pressure. A liquid handling means such as a syringe (68) is used to control withdrawal or addition of liquid.

Abstract: A circuit arrangement for adding, storing and reproducing electric counting pulses, is suggested, which preferably serves as an electronic kilometer counter of a motor vehicle with a distance transmitter (10). The circuit arrangement comprises an overwritable nonvolatile storage (16) which is divided into a series of storage registers (19) in which the counting pulses are stored by a one-unit shift code. When erroneous information occurs in any storage cell, the error of the indicated storage contents amounts to a maximum of .+-.1. This is achieved in that the control circuit (13), beginning with the first register (14), writes each new counting pulse into the next register (13, 12 . . . ) and, after reaching the last register (0), increases the contents of the first register and then the following respective registers by one unit with the next counting pulses. Such a circuit arrangement is to be used as a kilometer counter, operating time counter, quantity or piece counter, and the like.

Abstract: A brake control system has a controller (52, 53, 54) including hysteresis. To prevent over-shoot of control operation if a comparison between actual braking pressure (P.sub.act) and commanded pressure (P.sub.com) is applied to control valves which, for example, operate pneumatically, so that the brakes will not instantaneously respond, a difference pressure threshold (.DELTA.P.sub.G) is determined and, when the difference pressure level is passed by the difference pressure signal, the valves are controlled to operate in pulse operation, in which each pressure pulse (T.sub.E) is followed by a quieting or pressure-OFF time (T.sub.BER). The pulse sequence and the timing of pulses and pulse gaps is controllable in accordance with pressure levels, operating parameters, pressure difference levels and the like.

Abstract: An apparatus for determining the flow rate of a flowing medium having a substrate fastened at one end with a resistor arrangement disposed on the substrate which includes a layer-like measuring resistor (R.sub.S) and a layer-like heating resistor (R.sub.H). The heating output is regulated such that the measuring resistor (R.sub.S) has a constant electrical resistance, representing a flow rate of the flowing medium. By suitable provisions, such as a meandering pattern for the heating resistor (R.sub.H), the local resistance of the heating resistor (R.sub.H) crosswise to the flow direction is made to decrease toward the fastened end. Thus, the temperature generated by means of the heating resistor (R.sub.H) inside the substrate and the measuring resistor (R.sub.S) decreases toward the fastened end.

Abstract: A measuring device (60) measures the value (t) of a chosen parameter (thickness) of what has been lifted by a lifting assembly (40) from a stack of sheets (1) of material and allows the lifted material to be moved from the stack when the value is in a predetermined relationship to a reference value (T). One (45a) of a plurality of selectively releasable members (45) on the lifting assembly (40) is moveable in two horizontal directions to locate a sheet attached to the one releaseable members (45a) against locating pins (5, 6) on the work table (3) of the punch press (4). The entire system may be operated automatically by a controller (90).

Abstract: The invention is directed to an engine control system wherein fuel injection and ignition is dependent upon elevation. In this system, the elevation is detected via the maximum charge signal in the full-load operation of the engine. For this purpose, characteristic curves for the maximum fuel quantity corresponding to various elevation values are stored. A limitation of the maximum charging signal is carried out in the specific speed range in dependence upon the detection elevation in order to prevent overenriching by means of pulsations. Furthermore, a correction ignition angle adapted to the particular elevation and a corrosion factor for the injection time are effective which makes possible a full-load adaption of the motor at the elevation.

At least one injection hole is provided in the front cusp. The outer wall area of the front cusp which is disposed opposite to the valve seat face has a lower hardness than that of the inner wall area forming the valve seat face.

The intermediary center wall area preferably has a still lower hardness than the outer wall area. Thus, it is achieved that the front cusp of the nozzle element has a higher rigidity than in a known embodiment, without the valve seat face losing any hardness or that the protection of the outer wall area of the front cusp being unduly severly reduced against abrasive wear.

Abstract: An apparatus for damping courses of motion in particular for damping resilient wheel suspension systems in vehicles, having a damping piston that is displaceable inside a jacket tube which separates two work chambers and is connected to a piston rod. Between the work chambers there are flow connections, through which a flow is possible in only one direction, because of a unilateral actuation direction of separate check valves. The flow connections have throttle cross sections the size of which is definable by the position of a control slide inside a guide bore. The control slide is actuated via a control rod leading outside the jacket tube and is movable with two degrees of freedom. A motion in the direction of the first degree of freedom varies the throttle cross sections in the same direction, while a motion of the control slide in the direction of the second degree of freedom varies the throttle cross sections in opposite directions.
