Title: Measuring fluid flow inductively in partially filled tubes - is by multiplying flow speed and cross-section signals during varying flux period
Inventor: BONFIG KARL WALTER PROF DR ING
IPC: G01F1/58
Filed: 1978-12-27
Abstract: A method and sensor for measuring fluid throughout in partially filled pipes or open channels involve multiplying flow speed and flow cross-section signals together. A simple magnet arrangement producing a cycled direct field enables a change-over to be made from an inductive flow speed measurement to an inductive flow cross-section measurement using one sensor. An electromagnetic field alternately produces constant induction flux during the time period and linearly and trapezoidally time-varying flux during the next period. The flow speed is measured during the constant flux period and the cross-section during the varying flus period. The flow speed is measured from the voltage induced in an electrode pair and the cross-section using a conductor loop in the unfilled region.

Title: Microprocessor controlled safety monitor in motor vehicle - re-runs program to avoid erroneous operation due to parasitic disturbances
Inventor: HAUBNER GEORG
IPC: G05B19/048
Filed: 1979-01-31
Abstract: The program controlled monitoring system, such as a microprocursor system in a motor vehicle, can indicate an apparent failure due to parasitic disturbances. This is resolved by running the program again before operating any safety devices. The microprocessor controlled monitoring system (10) contains a monostable (101) whose inverting output is connected to another monostable (11). A JK bistable (13) acts as a coincidence detector whose output is connected via an OR gate (14) to a safety switch circuit (15). When the monitoring system monostable returns to its original state a short pulse is generated which passes via an RC circuit (18, 19) to a NAND gate (20). This causes the monitoring system to restart its program. An RC tuning circuit (22, 23) is switched from the monitor system to reset the JK bistable.

Title: Modular support grid for equipment rack cables - is assembled from square frames bolted together at corners
Inventor: FAERBER WILHELM ING GRAD
IPC: H04Q1/06
Filed: 1979-03-02
Abstract: A support grid for the cabling of racks in exchange equip. rooms is constructed from a number of identical square frames joined together at each corner with one screw. Each frame is built up from four tubular rods and four right-angle corner pieces. The latter have spigots which push into the tubes and are secured by pressing, pinning, welding, crimping or swaging. Half the thickness of each corner piece is cut away to mate with the corner of a neighbouring frame, so that all frames will lie in the same plane. The mating face of each corner piece is grooved to make the joint rigid when the fixing screw is tightened. Holes drilled through the corner pieces for the fixing screws have sufficient clearance to provide a working tolerance when assembling grids.

Title: Distance or position measurement circuit noise suppression - using EXCLUSIVE-OR pulse signal combination and edge triggering
Inventor: KUGLER ROLAND ING GRAD
IPC: G01D5/244
Filed: 1979-07-28
Abstract: The circuit with a pulse generator produces distance or position signals whose noise signals originating from pattern measure disturbance motions are extremely simply suppressed. Movement of the measure results in two oppositely phase shifted equal frequency pulse series. Movements of less than half a measure division are involved. The pulse lengths and intervals of the pulse series are equal or of the same order and are combined in an EXCLUSIVE OR gate to produce a time delayed clock pulse signal. The clock signal drives two flip-flops each also receiving a pulse series signal. Their outputs are combined in another EXCLUSIVE-OR gate to produce the measurement signal via two monostable flip-flops producing counting pulses off the leading and trailing edges.

Filed: 1979-09-04
Abstract: In formation of patterns by electron beam irradiation of resist, the resist is a surface migratable resist provided in thickness less than thickness required for pattern formation. Pref. the resist is formed on a thin film substrate supported by a non-electron backscattering substrate. The resist is exposed to a focussed electron beam to convert and fix the resist until the required pattern thickness is reached. Exposure duration control is esp. achieved by monitoring electron scattering by the converted and fixed resist. The nonelectron backscattering substrate is pref. Si, Si3N4, SiO2, Al2O3, polyimide, collodion or C. The resist is organic material, esp. silicone oil or tetraphenyl-tegramethyl-trisiloxane. Pattern line widths 100A can be formed as method avoids raggedness at the edges and provides control of pattern thickness and width. The resist pattern is useful in electrical contact control and light modulation, and may be used in situ, or may be used to transfer the pattern to another substrate for device formation using 20-50A X-ray irradiation.

Title: Two=way digital signal transmission - with solid state transmit and receive damping elements connected to two wire circuit
Inventor: LAURITZEN THORWALD J
IPC: H04L5/14
Filed: 1979-12-18
Abstract: The object of the circuit is to provide solid state digital damping between the transmit and receive functions of a two way data transmission link. Two assemblies of time delay elements are employed, connected to the transmission cable (KL). For the receive circuit (E1) these comprise passive delay elements (V1,V2,.. Vn-2,Vn-1) connected in series. Similar elements, which may be active, (V'1, V'2,..V'n-2,V'n-1) are provided for transmitter (S1). The elements of the latter are connected through high output impedance amplifiers (SV1,....SVn) to corresponding points on the receiving delay line (K1). The delay of each unit corresponds to one half of a single bit transmission time. When transmitting the receiver (E1) part of the circuit obtains a signal damped to 1/n of the voltage level of a digital high, or one, pulse whilst the transmitted pulse is of unit value. Incoming pulses are blocked from the transmitter (S1) by the amplifiers (SV1,...SVn), and summed to the correct level by the receive delay line.

Title: Electrical plug connector with soldered joint - has lobed-edge deep drawn separation wall
Inventor: BERGINSKI WERNER-ERNST
IPC: H01R4/02
Filed: 1980-06-14
Abstract: The electrical plug connector consists essentially of a sleeve shaped entry part of round cross section, a sleeve shaped circular solder head (2) and a bowl shaped separating wall (3). The solder head (2) is formed for axial entry of the conductor, and the separating wall (3) opens equiaxial to it. The entry part (1) and solder head (2) both have lengthwise slits, and at the transition between the two, register tongues (7) are formed and bent outwards for firm fixing in a plastic housing. The separating wall (3) is deep drawn from an anisotropic metal forming lobes at its opening edges to prevent solder or flux from entering the adjacent section when the feed conductor is soldered in. By forming these lobes in the separating wall edges, a larger surface area, for the same diameter, is obtained, increasing the possible electrical power transmission capability.

Patent DE-3100322-A1 (DE)
Title: Process and appliance for preparing a homogeneous mixture
Inventor: THOENE ERNST
IPC: B01F15/00
Filed: 1981-01-08
Abstract: A process and an appliance by means of which at least two liquids of different viscosity are mixed together under pressure in mixing stages. In the first mixing stage, the liquid streams are brought together to produce a coarse mixture. In the second mixing stage, the coarse mixture is compressed to form a homogeneous mixture with a determinable viscosity. The viscosity of the homogeneous mixture is determined continuously and, on the basis of the measurement results thus obtained, the proportion of the one or the other liquid stream is increased in order to be able to maintain as constant a viscosity as possible. This constant viscosity is defined on the basis of the particular application, for example by the minimum requirements a fuel suitable for a particular engine has to meet. Thus it is possible to use high-quality and expensive fuels only insofar as the operation of the engine absolutely requires their use. Additionally, the system can be used to circulate the contents of storage tanks in such a way that setting (curing) of the liquid in the storage tank is avoided.
