Abstract: An electric hair dryer wherein a collapsible hood defines one or more plenum chambers for heated air and has a foraminous inner panel which is adjacent to the hair when the hood is placed over the head of the wearer. The hood has a hollow extension which is adjacent to the chest of the wearer and is separably connectable with the slotted detachable cover of a housing for the electric motor which drives a rotor for supplying heated air into the plenum chamber or chambers. The rotor is installed in the cover and is disposed downstream of an air heating unit which is mounted in the interior of a hollow cylindrical or frustoconical air guide and surrounds a tube for admission of cool atmospheric air into the space around the motor. The bottom wall, the front wall and the two lateral walls of the housing are formed with ports which admit atmospheric air into the air guide as well as into the tube.

Abstract: An electromagnet which serves particularly to control a fuel injection valve for fuel injection systems in internal combustion engines. The electromagnet includes an inner core of soft-magnetic material, which is surrounded by a magnetic coil. An outer core at least partly surrounds the magnetic coil and has an outer pole located in the same plane as an inner pole of the inner core. On one side of the magnetic coil, between the inner core and the outer core, there is a first annularly embodied and radially magnetized permanent magnet, and on the other side of the magnetic coil there is a second annularly embodied and radially magnetized permanent magnet. Facing the poles, there is an armature, which at one end is joined to a valve needle that has a valve body cooperating with a valve seat, and on its other end forms a first working air gap with the outer pole and a second working air gap with the inner pole.

Abstract: A glow plug electrically heated during start-up to help bring the air-fuel mixture of an internal combustion engine to ignition temperature when the engine is cold, instead of being turned off as soon as the engine is running, has its heating current controlled so as to maintain the glow plug temperature within a desired range, as the result of which the engine can be made to run more quietly and more smoothly under many conditions. The current control unit which varies the glow plug current responds to the output signal of a computing unit responsive to various engine operation parameters, including especially a signal representative of the rate of feeding fuel to the engine.

Abstract: A method and an apparatus are disclosed for determining the flow rate of a flowing medium such as the amount of air supplied to an internal combustion engine. The apparatus includes at least one temperature-dependent resistor arranged in the flowing medium. For this purpose, an arrangement is provided which applies a quantity dependent on at least the flow rate to the temperature-dependent resistor. The method includes the step of abruptly reducing the flow rate dependent quantity to a value such as approximately zero in the presence of a flow-rate value lying below a predeterminable threshold value. Because the reduction takes place only for a predetermined period of time, normal operation will be resumed automatically when the flow rate rises again. A hot-wire air-flow sensor is arranged in the intake pipe of an internal combustion engine and the output signals thereof are a measure of the amount of air inducted by the internal combustion engine.

The laminate is most useful in fabricating envelopes or packages for electronic components featuring EMI and RFI shielding an electrostatic dissipation. The laminate comprises outer layers of an electrostatic free plastic and a middle layer of conductive fibers in a low density mat of between 0.2 and 0.5 ounces per square yard.

Abstract: A sealing for a rotary impeller blade partially extending outwardly from a rotor of an impeller pump includes two sealing strips of plastics, the ends of which abut against the opposing side faces of the blade in the region of a slot found in the rotor, and two respective supporting members of metal. Each supporting member secured to the assigned sealing strips reliably supports the sealing strip whereby the sealing strips resist to vibrations occurring at high speeds of the pump during operation.

Abstract: The invention is directed to a circuit arrangement for controlling the current through an electric load such as an electromagnetic load. A current-controlling element controls the current through the load in response to a control unit. The voltage at the load is compared with a voltage which depends on the control unit which drives the current-controlling element. The current through the electric load is then controlled in dependence upon the result of this comparison. An embodiment is described by means of which the entire circuit arrangement is protected against function failures or even destruction.

Abstract: To maintain stability of operation of a vehicle entering a curve, for example with excessive speed upon entering the curve, and application of the vehicle brakes by the operator, the braking effort (P.sub.HA) applied to the rear wheels or rear axle of the vehicle is controlled to be at a low and constant level, substantially below the braking effort (P.sub.VL, P.sub.VR) applied to the front wheels of the vehicle, and for a limited period of time (t), which may be a predetermined time duration, under control of a timing element (4), or which may depend on counted braking cycling events, of braking effort applied to the front wheels, for example under control of an anti-brake locking or blocking system (ABS). For example, a counter (8) may count two cycles of operation of the ABS and then release the low, constant braking effort phase applied to the rear wheels of the vehicle. Stability of operation of the vehicle, in the curve, is thus maintained.

The face plate is coupled to the housing via a pair of articulated joints, which may be adjusted to a selected one of many possible angles relating the supporting plane of the face plate with the axis of the spindle. The face plate contains a relatively large hole through which the spindle projects with said cutter being positioned beyond the supporting plane, so that the cutter may be seen during normal operation. A protractor scale is engraved on at least one of the articulated joint parts to identify a cutting angle. In another embodiment, a plurality of click stops are provided on one of the articulated joint parts for accurately setting a selected one of several angles to which the joint may be moved.

Abstract: The luminance signal is connected to a transmission channel which includes a subtraction circuit (3) and a branch circuit, to apply a subtraction signal to the subtraction circuit. The branch circuit includes a band-pass filter connected to receive the luminance signal and a controlled amplifier (5) serially connected with a band-pass filter. The branch circuit is additionally connected to a circuit to derive the control signal for the controlled amplifier, the control signal being obtained from a control signal generating circuit which generates the control signal as a function of the portion of the luminance signal which is within the band-pass width of the chrominance subcarrier. The signal can be obtained, for example, by forming a level signal representative of the luminance components based on the color difference signals; and/or by synchronous demodulation of the luminance signal with respect to the chrominance subcarrier; and/or by a comb filter.
