Title: Prodn. of mixed manganese-lead dioxide - having high electrochemical and catalytic activity
Inventor: FABER PETER DIPL CHEM
IPC: B01J23/34
Filed: 1976-07-03
Abstract: Electrochemically and catalytically active substance is produced by introducing O3 into an aq. soln. contg. (CH3COO)2Mn and (CH3COO)2Pb at 70 degrees C or more, whereby a mixed dioxide of Mn and Pb is precipitated. A Mn-Pb dioxide is much more active than the same quantity of physically mixed MnO2 and PbO2. Specifically, the molar ratio Mn:Pb can be 1000:1 to 1:1000. The total concn. of Mn (II) and PB(II) acetates in the aq. soln. is between 2 wt.% and the saturation concn. The O3 concn. is 20% w.r.t. the soln. The pptd. mixed Mn-Pb dioxide is washed and dried at 120 degrees C in the air or at 70 degrees C under vacuum. The mixed oxide can be additionally treated with conc. HNO3, pref. at the boiling temp. The starting soln. may contain up to 1% of an acetate of Na, K, Li, Co, NH4, Ag, Ni, Cu or Cr which promotes the reaction.

Title: Microprocessor for operating on single bits - has input and output data-bus lines, two ROMS and logic units with OR=gates and xOR=gates
Inventor: SCHEMPP OTTO DIPL ING
IPC: G06F9/22
Filed: 1976-07-31
Abstract: The micro-processor incorporates a databus (2) connected with a multiplexer (5) and an ROM (4). Incoming data passes through another ROM (8) to a single unit processor which combines a pair of flip-flops (FF). The input of the flip-flops is provided by a pair of OR gates (9, 16), which receive one input each from the input data multiplexer, and one from a feedback loop from the output databus. The output of the flip-flops is transferred to the output ROM (4). The input ROM is triggered by a signal from an X OR gate (6) which collects one signal each from the input data line and the output multiplexer (5).
Patent DE-2637247-A1 (DE)
Title: Primary shaft seal combined with secondary seal - uses piston controlled by seepage pressure from primary seal to apply secondary seal
Inventor: NOTHACKER HORST ING GRAD
IPC: F16J15/16
Filed: 1976-08-19
Abstract: The shaft seal assembly comprises primary and secondary face seals. The space between the seals is connected by a duct to the one end of a hydraulic piston coaxial with the shaft. The other end of the piston confronts a collar mounted on the shaft. If the pressure of seepage from the primary seal rises the piston is moved into engagement with the collar to establish the secondary seal. The collar may be axially slidable on the shaft, and when the piston acts on the collar the latter is pushed back against the pressure of a spring which then determines the pressure of the seal.
Patent DE-2641525-A1 (DE)
Title: Amplifier with variable gain - has control voltage applied to amplifier input and separated at its output and used for gain control
Inventor: GIES JOHANNES DIPL ING
IPC: H03G3/30
Filed: 1976-09-15
Abstract: The amplifier gain is determined by the resistance of a variable control resistor. A DC voltage (Uo) and an AC voltage (Ue) are applied to the amplifier (1) input, whose output is connected to a filter (TP, C2) separating two voltages. One of the voltages (Ue) is the voltage to be amplified, and the other constant amplitude voltage (Uo) is the control voltage. Its filter (TP, C2) outputs is connected, possibly through a rectifier, to the first input of a differential amplifier (4) to whose second input a variable control voltage (UF) is applied. The variable resistor (FET 1) is so controlled by the differential amplifier (4) output, that the amplifier (4) input voltages are as equal as possible. Resistance of the variable resistor (FET 1) is about the same for DC and AC.

Title: HF medical diagnostic appts. - has wide band multiple element transmitting aerial system and recording indicator and oscilloscope
Inventor: GUETTNER WOLFGANG JOACHIM
IPC: A61B5/055
Filed: 1976-11-19
Abstract: The high frequency medical diagnostic apparatus has a broad band multi-element aerial system on one side of the patient, and on the other side is a wide band measuring unit. The length of the distance between determines the characteristic of the aerial diagram. The wide band measuring head has a capacitative loaded diode arrangement for measuring between 0.1 to 1000 MHz. The capacitatively coupled diode rectifier section develops a h.f. voltage of between 0.7 to 0.01 mV. This is followed by a high pass filter and a two way measuring bridge, an amplifier, a chopper and a synchroniser, terminating with an XY recording indicator and oscilloscope. These are connected back again to the input h.f. generator, the output signal being wobbulated.

Title: Spring brake with automatic adjustment - has split cone rings allowing movement in one direction only
Inventor: GAMPE KARLHEINZ ING GRAD
IPC: F16D65/14
Filed: 1976-11-27
Abstract: The spring brake with automatic wear adjustment has split cone rings (4, 5), together with coupling components, adjusting rings (9, 10), and a taper (13) and a cylindrical (1) bush. The adjusting rings can be mounted on the armature disc and the solenoid body, and have locking screws (11, 12).

Title: Spark ignition IC engine - has exhaust valve inclined relative to cylinder centre line and seated in head recess with extension receiving sparking plug
Inventor: SEIDL JIRI DIPL ING
IPC: F02B23/08
Filed: 1977-07-09

Title: Miniature non-reactive electromagnetic range meter - uses crossed coil transceivers suitable for use with mechanical or biological subjects
Inventor: KEBBEL ULRICH
IPC: A61B5/107
Filed: 1977-07-21
Abstract: The range measuring equipment comprises a transmitter assembly consisting of three sets of coils mounted at right-angles to each other and each driven from its respective generator (1-3). Two of the three coils are driven at the same frequency but with 90 deg. phase-shift. The third is driven at a frequency differing from the first by a given value. A receiver assembly comprises three similar crossed coils, each connected to its respective receiver. Each receiver contains an amplifier, bandpass filter and demodulator stage. The output of each receiver is connected to an adder. The summed signal passes through a low-pass filter to remove the frequency difference component. The signal is then finally linearized and is proportional to the distance between the transmitter and receiver sites.

Title: Wear and/or corrosion resistant coatings for machine parts - applied by friction welding, and suitable for coating piston rings with molybdenum
Inventor: VOSSIECK PAUL
IPC: C21D1/06
Filed: 1978-07-15
Abstract: The parts are made esp. of cast iron, steel or Al; and the coating are applied by heating which causes at least partial metling of the surface of the part. the heat is generated by friction of the part with a tool moved with high kinetic energy and/or high pressure w.r.t. the surface of the part. Conventional metal and/or metal-ceramic coating materials, esp. powders, are pref. located between the part and the tool when the friction is generated; and these coating materials may be used to form a coating on the part prior to melting via friction causing a charge in structure. The process is pref. used on piston rings, sealing rails, cylinder liners, and the valve seats, in IC engines. The simple, economic and reliable process avoids costly and difficult operations necessary with conventional coating processes.

Patent DE-2839140-A1 (DE)
Title: Hot drinks machine - has two stage heating unit ensuring full flavour extraction from powdered extract
IPC: A47J31/54
Filed: 1978-09-08
Abstract: The continuous heater, pref. an electric heating element (10) heats up the beverage liquid and can be operated in stages with a variable heat output so that in the first stage it can be switched to a low output for smaller quantities whilst in the second stage it can be switched to a higher output to make larger quantities. The heating unit can comprise a first heating resistance (18') and a second heating resistance (18") wherein the second resistance can be switched onto the first. With the lower heat output, more time is required to vaporise the set water content so that the rate of flow of the hot water in the riser pipe is reduced to allow sufficient time for the flavour to emerge from the coffee powder.
