Title: Intake air flow measure for combustion engine - uses cooling of hot wire resistor in regulated bridge network
Inventor: HAFNER UDO ING GRAD
IPC: G01F1/698
Filed: 1978-10-20
Abstract: The device measures the intake air flow rate in a combustion engine. Three temp. dependant resistors are inserted in the intake duck and form a bridge network with two other resistors. A defined current flows through the second hot wire resistor to heat it to its operating temp. The first resistor acquires a resistance determined by the intake air temp. and acts as a reference for the second resistor. The flowing air cools the second resistor which unbalances the bridge. This is detected by the control amplifier which uses the voltage controlled current source to drive more current through the bridge to balance it. The current required to balance the bridge is a measure of the air flow rate. The complete circuit is mounted directly on the intake pipe.

Title: Seismic survey method using shock wave reflections - employs linear array of blast holes at rectangular increasing depths and surface
Inventor: KREY THEODOR PROF DR
IPC: G01V1/13
Filed: 1978-12-04
Abstract: The technique involves study of substrate beneath the earth's surface by the exploding shot at or near the surface detecting reflected shock waves by a number of surface geophones placed on the surface in a matrix array and analysing the results. Shot may be distributed in either a 2-dimensional or a 3-dimensional manner. The preferred method uses a linear track with shot exploded at steadily increasing vertical depths for equal horizontal spacings. Geophones placed in a surface rectangular matrix detect both direct and reflected waves; the frequency is typically 25 Kz and the vertical shot spacing 10m, and geophone lintes 60m apart. A distance/time plot for the response of a particular geophone from a particular shot line gives a linear result (1) for the direct signal, a curve (2) for the response from a fault tangential to the line at a point where the equivalent depth is found. An interference (Fresnel) zone is found (3) over a space/time region where the frequency interval is equivalent to half a wave length either side (4).

Title: Continuous filament yarn prodn. without godet(s) - using jets and enclosed guide tubes to produce coherent yarns direct from spinning
Inventor: HOFFMEISTER ROMAN DIPL CHEM DR
IPC: D01D5/02
Filed: 1979-07-23
Abstract: In producing continuous filament yarns of polyester, polyamide or polypropylene at speeds of 3000-6000 m/min., the newly-spun filaments emerging from the cooling zone are withdrawn through a nozzle into an attached guide tube. At least during the starting-up period, a current of gas is fed through the nozzle in the direction of yarn motion to transport the filaments through the tube, whereby they emerge bunched into a coherent yarn. After emergence from the guide tube, the yarn continues through a cooling section and a cooling tube, similar to the guide tube, surrounded by ambient air. A dressing may be applied to the yarn after the guide tube of cooling tube, and the yarn is wound without touching a godet. The process eliminates the need for a separate dividing process for sepg. a tow into several yarns. The filaments quickly cohere into a yarn, permitting redn. of the tension by 25-50%, and giving a considerable increase in filament uniformity, the yarn count variation being 0.5-0.9% (Uster).
