Combined device for the hygiene of the hair and for

do not care

309848/0780

The device which is the subject of this discussion comprises four different parts which the four required of him Functions correspond; these concern the hygiene of the "hair *" and the care of the face. This device is not intended for therapeutic use Intended use. . \ ■

Of the four functions, two become simple electrical Circuit arrangements ensured while the other two. make use of electronics «^.

The four parts are shown in Figures 1 through k ;

Since they have certain components in common, they can be used in any

Shades can be built in by appropriate switchovers. Various methods can be used to make these switches: keyboard, buttons, etc .; -4e-these devices are - not shown on the drawings, which only indicate the part in operation for each application.

The four functions of the device are thus described in connection with the figures: "-..- ■

In Fig. 1, which shows the schematic structure of the control represents the specific part of the skin resistance * 1 denotes a micro-ammeter with an adjustable Resistor 2 is connected in series, which once and for all corresponding to the internal resistance dee of the micro-ammeter is set.

3 and 4 indicate two in contact with the user Electrodes. \

The delay system, which enables the measurement time to be limited to avoid a polarization _{effect 4,} consists of a transistorized unit with a semiconductor 5 which actuates a relay 6. By operating the

Commissioning contact, clocks 7, the capacitor 8 is short-circuited via the resistor 9. At this point in time, the base of the semiconductor 5 is at the negative * potential through a resistor 10.

The relay 6 is then energized, the contact 12 is closed, and the micro-ammeter connected in the current path of the electrodes 3 and k indicates the current flowing between the electrodes and thus the skin resistance of the user. The start-up contact 7 is then at & t, the capacitor 8 consequently charges slowly via the resistor 11, which can be set according to the desired delay. The capacitor 8, which has reached its maximum load, therefore has a positive voltage

the base of the transistor 3 / i at this point in time the current of the collector of transistor 5 is at zero potential, and at the same time the relay 6 is excited, the contact 12 is thus opened. The first process for determining the general state of the electrical line resistance of the user has been completed.

«.R Before performing the second process, dg.3 · first

Part of the device (Fig. 1) is switched off so that the user · only remains in contact with the return electrode k. The second part of the dfrp device shown in Fig. 2 then comes into operation, and the user uses the spatula 13 to determine the favorable zones on the face or on the scalp. This spatula 13 is connected via a safety resistor 15 to the base of a transistor I * f; the gain coefficient of the transistor is controlled by a potentiometer 16 connected between the base and the e of the transistor Ik. The negative return is ensured by the electrode h. The potentiometer 16 is set according to the value which was previously read on the micro-ammeter 1 ■ during the previous process; this value is transferred to the scale of the potentiometer 16 and thus ensures the gain of the amplifier.

At this moment the conductivity of the transistor I ^ between the transmitter and the collector is triggered, which is via the micro-ammeter 1 the relay 17 is actuated, since with the help of this micro-ammeter it is very easy to get close to the investigated Can recognize zones and their favorable condition. Is this state very favorable, the relay 17 is energized and controlled

now an electrical switch, creating a red illuminated sign l8 is brought to light up and a green illuminated sign 19 is made to go out, which always lights up when the spatula 13 is located outside «the favorable zone.

If a sensitive area is detected with the help of the microamperimeter or of the red illuminated sign l8 is detected, you can see their Measure the condition very precisely by means of a suitable switching system, which enables the spatula 13 and the electrode 4 to be attached

afp shown in Fig. 3 to connect the third part of the device.

The 'at the same time again switched Mikröamperemeter is the resistance between the spatula 13 and the Rückl'eitungselektrode k by means of an adjustable resistor 20, the ¹ above, according to the internal resistance of the measuring de & ns' has been adjusted. This measurement obtained on the micro-ammeter 1 shows the user the state of the zone according to a table which was previously established by comparative measurements on different people or by previous measurements on the user himself.

After the zones have been recorded and measured, they can be excited by switching the spatula 13 and the electrode k to another part of the device, which is shown in Fig. M- ; the latter shows the diagram of the oscillator, which is used to stimulate the skin with a micromassage. These micromassages do not claim to have any therapeutic value. '_ ■ - ■■

On the circuit diagram shown in Fig. ^ F, two resistors 21 and 22, which form the voltage divider, charge the capacitor 23, which works as a tilting oscillator with the aid of äefe- ^: potentiometer Zk set by actuating the transistor 25 via the windings 26 and 2? T whereby low-frequency signals are obtained, which are converted for use with the aid of the secondary winding 28 of the transformer; the neon tube 29 here takes on the role of the peak voltage limiter and thus ensures an output voltage of about 60 volts peak, to comply with electrical standards.

Furthermore, a resistor 3P-4e limits the current between the electrode h and the spatula 13, which is also regulated with the aid of the potentiometer 31 in accordance with the physiological reactions of the user.
