Title: Measuring etching time of permeable layer on printing cylinder - by measurement of rate of voltage increase between electrode and cylinder
Inventor: BRUEGGER ARNOLD A
IPC: B41C1/02
Filed: 1977-03-05
Abstract: Process and device for measurement of the penetration time and determination of the instant of penetration of a permeable layer by etching of intaglio printing cylinders with an etching fluid. A perforated protection strip is fastened on at least part of the cylinder circumferences and a measuring etchant-resistant electrode is put on the protection strip nto form a galvanic element with the metal coating of the cylinder and the etchant diffusing through the permeable layer.

Title: Error trapping detector and corrector for binary data - has few components and operates at lower speed by use of weighting pattern retained in memory
Inventor: PROEGLER MAX DIPL ING
IPC: H03M13/17
Filed: 1977-10-14
Abstract: The error detector and/or correcotr, for binary data, has error patterns and weightings corresponding to them retained in a memory. If the weighting conditions are never fulfilled, the error patterns is recognised as such but is indicated as uncorrectable. The advantage lies in attaining forward correction based on error trapping methods without resorting to large numbers of circuit components and high speeds. The power consumed is also less than would be the case with a large number of components. The number of data which may be checked back is within a range 0 to n-k-1-b, where n is the number or codes, k is a function of the comparator and b a function of the error checking bit length.
Patent DE-2759286-A1 (DE)
Title: Purificn. and heat recovery from exhaust gases - using injection of volatile liq., e.g. water, under pressure to recover heat by driving turbine with subsequent recycle of liq.
Inventor: FUNK HARALD F DR
IPC: F01K21/04
Filed: 1977-12-30
Abstract: Exhaust gases, esp. from combustion processes before discharge to atmosphere, can have heat recovered from them and be purified by filtering the gases, injecting a volatile material (e.g. water or refrigerant) into the gases under pressure, and passing the resulting vapour stream through a turbine. The exhaust vapours from this are cooled to condense out the liquid which is then recycled. The gases can be further compressed and processed to remove contaminants, esp. acidic vapours. Used for purifying exhaust gas stream before discharging to atmosphere. The process uses direct heat transfer by use of injected liquid instead of surface heat exchange.

Title: Locating, sizing and clamping drill bit segments for welding - on a fixture having a three jaw chuck and registration plate
Inventor: SCIAKY ALBERT M
IPC: B23K15/00
Filed: 1978-04-05
Abstract: A drill bit is constructed from like segments by machining a cavity into the end of the shank portion of each segment for receipt of respective registration pins protruding from a fixture. Rolling cutters mounted on the bit leg portion of each segment are contacted with a sizing gauge ring and the faces of adjacent segments are brought into abutment while maintaining the gauged surface of the cutters in contact with the sizing gauge ring. The segments are clamped in fixed relationship to one another and the abutting faces between segments are welded together. Used to mfr. rotary drill bits e.g. for oil well drilling. The sizing and clamping of the drill bits is effected without frictional locking the parts and the accuracy of bit location is repeatable. The operator is not required to hammer the parts during the sizing operation. The segments may be aligned without the use of a multiplicity of closed circuit television systems to establish the three points which define the weld plane in conventional alignment systems.

Title: Semiconductor module mfr. - by ion implantation basing heat treatment on laser radiation of test figures
Inventor: SCHAUMBURG HANNO DR
IPC: H01L21/268
Filed: 1978-08-30
Abstract: In a semiconductor manufacturing process where ion implantation is followed by a heat treatment to cure lattice dislocations, a test figure is first subjected to the implantation followed by intensive optical irradiation and finally its electrical properties are measured. The test results form the basis for the subsequent treatment of the semiconductor modules themselves. Process supplies more positive data than a low-temp. treatment of a wafer with test figures and extrapolation of the results. The scatter in the results can be reduced.
