Title: Amplifying factor adjustment circuit for IF amplifier - selects control signal for each reception range for receiver tuning and stores control signal
Inventor: GERBER HORST
IPC: H03G3/20
Filed: 1989-06-06
Abstract: The amplifier (9) is fitted in an HF receiver, tunable in at least one freq. range.  The tuned reception signal is converted to an IF and amplified under a control of an adjustable control signal.  The circuit for each reception range selects the controll signal such that at a HF reference siganl, the reception range of the tuned receiver provides an amplified IF signal of a preset value. The circuit stores the control signal determined values for different reception ranges.  The  control signal is adjusted to a stored value of each reception range after switching-on of the receiver, or its change-over to a different reception range. Pref. the circuit is supplied with an IF amplifier signal, which. indicates the IF signal level at the output (10) of the IF amplifier. ADVANTAGE - No need for external measure for the adjustment step.

Title: Structured surface web mfr. - by using thin carrier with adhesive on granule layer to give natural irregular surface effects
Inventor: RUPALLA BERND
IPC: D06N7/04
Filed: 1989-06-13
Abstract: To produce webs with a structured surface, such as for covering walls and ceiling or furniture, a supple and thin carrier, with fine openings, is laid smoothly and without creases on a granule layer, so that an adhesive can pass through the carrier and penetrate the granule layer. After adhesive bonding, it is removed with the granule layer. Pref. the carrier is detached while the adhesive is still tacky, and rolled, and then later spread out for the adhesive to set and harden. The pref. carrier is an open woven fabric a gauze. The granule layer, pref. of quartz sand, is a natural material which is washed and spread out. The surface opposite to the carrier can be sealed, or covered with a transparent layer with a smooth surface, or the carrier with the granules can be d bonded to a stiff underlayer or otherwise secured. The woven fabric has yarns which are penetrated by the adhesive, so that the adhesive passes into adjacent yarns and wholly or partially through them. The edges of the material are secured against slippage by passing anchor pins into the granule layer. Plates can be detached from the web in the form of tiles. ADVANTAGE - The process gives a web with a natural surface structure, with irregularities, which can be used as natural material.

Inventor: KOBLITZ RUDOLF DR
IPC: H03K5/24
Filed: 1990-06-01
Abstract: 2.1 From an amplifier and an integrating capacitor followed by comparators, an integrator with comparator outputs can be formed. The usable input voltage range for the comparators, however, is normally 2 to 3 V less than the operating voltage. A corresponding integrated circuit having this function would need a relatively large chip area. 
<??>2.2 The usable input voltage range for the comparators can nearly reach the magnitude of the operating voltage and the circuit can be accommodated on a reduced chip area by using transistors operated in saturation and a special circuit technique. 
<??>2.3 For electrical circuits needing integrators with comparator outputs, for example ramp function generators.

Title: Arrangement for humidity reduction -  in air or gas drier and heat exchanger
Inventor: JENSEN HERBERT
IPC: B01D53/26
Filed: 1990-09-03
Abstract: There are enormous variations in the quantity and temp. of gases passing through gas coolers arranged as heat exchangers using a coolant.

Title: Polymer mix prodn. to fixed viscosity - by measuring stirrer power consumption, comparing with target value and regulating speed of stirrer
Inventor: SUNDER JOACHIM
IPC: B29B7/72
Filed: 1990-11-21
Abstract: Mixing is controlled by continuously testing the material temp., the speed of the mixer and the power of the mixer motor, and the mixer speed is used as regulating parameter by comparing value with a set target level. The viscosity of the material after a set mixing time is adjusted by using as further parameters the movement of the floating wt. at the mixer inlet plus factor(s) reflecting the geometry of the mixers; these data provide a continuous value for the power needed to obtain pref. viscosity; continuously comparing the value with the actual value of power used enables an estimated mixing time to be reached, and the speed of the stirrer is finally regulated after comparing that time with time set beforehand.       Pref. if the method produces an estimated mixing time which is less than that set beforehand the speed of the mixer is reduced and vice versa. The geometry of the mixers is derived from the deg. to which the mixing vessel is filled. The viscosity is partly w.r.t. mixer temp. and partly the speed of shear or stress of the material which in turn depends upon the stirrer speed.       ADVANTAGE - Viscosity of the polymer material is regulated within a set mixing time. (Dwg.0/1)

Abstract: The PBX terminal set engagement testing uses a central control (ZR) with a memory (SP CNFG, CNCT) for the installation configuration, data, and for connection state information signals. The central control is triggered by an engagement segment from a terminal (T1) for testing the state of the office sets (TR1-n). - After the central control triggering by a first, or second, instruction of the terminal, it tests the PBX installation, according to a preset criterion, for its free state, possibly w.r.t. a second terminal (12) coupled to the respective office set. On a positive result of the second test, the central office couples the first terminal to the second one, with release of the first office set (TR1).

IPC: G01N33/00
Filed: 1990-12-06
Abstract: In order to increase the reliability of detection of gaseous contamination in containers, gas (G) from the container is subjected to several different methods of analysis (54a to 54d), each of which emits differing output signal courses (I1 to I4) depending on the contaminants and their concentration. A vector of the state vector type (P &cir&  NOt GAS) is formed with the output signals (I1 to I4) as a state variable and checked to see whether it defines a permissible or an unacceptable state of contamination (56).
