Title: Integrated circuit operational amplifier for filter circuits - has IGFET structure using high common mode and with power supply noise immunity
Inventor: ROESSLER BERNWARD DIPL ING
IPC: H03F3/45
Filed: 1979-09-24
Abstract: The operational differential amplifier is employed in the construction of filter circuits in digital telecommunications installations. The object of the proposed modification to an operational amplifier made in IG-FET technology is to improve its common mode signal and power supply noise immunity. It is achieved by an alteration in the technological construction of the integrated circuit. The power supply voltage divider (18,19,20) employs one FET (18) constructed as a depletion type FET operating in a saturated condition, and similar to the drain resistors (3,4,300), instead of as an enrichment type. The proposed construction can be achieved by making the FET in the same process step as the drain resistors on the chip.

Title: Enzymatic determination of substances in fluids e.g. blood - with enzyme separated from fluid by a semipermeable membrane
Inventor: SCHINDLER JOHANNES GEORG DR
IPC: C12Q1/00
Filed: 1980-03-19
Abstract: Quantitative determn. of an enzymatically reactable substance is effected using an enzyme which brings about a reaction of the substance which is detectable with physical measuring means, the measuring medium contg. the substance to be determined being in contact with a semipermeable membrane which is substantially impermeable to the enzyme but substantially permeable to the substance to be determined. The medium contg. the enzyme is circulated in a closed circulation system consisting of at least diffusion unit containing the semipermeable membrane, a measuring element and a pump. Used for quantitative analysis of enzymatically reactable substances, e.g. in biological fluids such as blood, serum, etc. The enzymes used are in the readily available and highly-active native form, but the enzyme-contg. closed circulation can be re-used in a large number of determinations. The method is free from immunological and sterility problems and therefore suitable for direct measurement in patients with recirculation of blood to the patient. The method is suitable for all types of enzymes.

Title: Expansion joint cover for bridges - has intermediate cross member supported on rubber blocks mounted on cantilevers
IPC: E01D19/06
Filed: 1980-05-22
Abstract: The expansion joint for bridges and similar structures is fitted between the cross member (LRI) of one part of the structure and the cross member (LR2) of the adjoining structure. An intermediate cross-member (L) is mounted in cubic elastomeric blocks (4), which rest on cantilevers (TKI) which project alternately from the two parts of the structure. Relative movement between the cross-members, due to thermal expansion or contraction, is absorbed by shear deformation of the elastomeric blocks. A flexible sealing strip is fitted in the gaps between the cross members. The strip is folded along its centre line as the gap between the cross members is reduced. The elastomeric blocks ensure that the loads are distributed equally over each cross-member.

Title: Frequency or phase relationship measurement system for pulse - measures pulse duration of signal by bringing it into coincidence with auxiliary signal
Inventor: DAUTE OTTO ING GRAD
IPC: G01R23/00
Filed: 1980-08-09
Abstract: A circuit for determining the variations with time of a signal or the relationship of the signal to a comparison signal measures frequency, phase, or pulse duration variations. It operates simply, noncritically and economically. An auxiliary signal is brought into coincidence with the signal being investigated using a coincidence detector and control circuit. The effects on the signal produced by the coincidence detector of the irregularities in the residual control speed are used for evacuation of the measurement parameters. The auxiliary signal is generated using a monostable multivibrator whose output pulse width is regulated. The multivibrator is triggered when the monitored signal reaches a defined condition. This condition is detected by evaluation of a signal produced by the circuit which generates the monitored signal or of a signal derived from the monitored signal.

Title: Continuous internal pipe welding rig - with tack welder, inner and outer forming rolls and welding head
Inventor: KIRCHHOFF WILHELM
IPC: B23K9/025
Filed: 1980-11-27
Abstract: Pipes, shaped from steel strip, are joined by internal welding of a longitudinal gap by moving them relative to a stationary arc welding rig. Sections are tacked together to form a continuous strand and are later severed when the weld has been completed. Pairs of inner and outer curved rolls shape the adjoining strips near the gap to the proper curvature. This simplifies the welding procedure and can be used even for tubes with a large dia. Unproductive ancillary times have been reduced to a min.
