Title: Operational amplifier referred to digitally stored average input - obtains average input from detected peak values of output of magnetoresistive potential divider and maintains when input is removed
Inventor: GLEIM GUENTER
IPC: H02P6/16
Filed: 1992-05-15
Abstract: The operational amplifier has a middle point (A) of a magnetoresistive sensor (R1, R2) connected to one of its inputs (Ui) referred to a potential (Um) proportional to the average input, which is obtd. from the max. and min. detected by diodes (D1, D2) and memorised after A/D conversion. The stored digital value is reconverted (D/A) to analogue form and applied to a resistance matrix (R3/R4) from which the reference potential is taken. The edges of the output square wave (Up) coincide with zero-crossings of the input. USE/ADVANTAGE - Esp. for pulse commutation or control of rotational speed of motors. Reference value once worked out is maintained against all influences.
Patent DE-4216940-A1 (DE)
Title: Metallisation of the inside of holes in plastic (esp. PTFE) circuit boards - by 2 stage metallising, comprising initial deposition by sputtering, followed by electrolytic deposition as usual
Inventor: BAUER MARKUS DIPL ING
IPC: H05K3/40
Filed: 1992-05-22
Abstract: A process is claimed for metallising the walls of drill holes in plastic printed circuit boards (I) by 2-stage metal deposition, using elecrolytic metal deposition in stage 2. The novelty is that the metal is deposited in stage 1 by sputtering. The sputtering process is continued until a metal layer at least 0.5 micron thick is formed, even on the inaccessible parts of the hole. Through-holes with length more than 4 x dia. are sputtered from both ends, and the process is applied to holes with dia. at least 0.5 mm. The board is pretreated by sputter-etching. Pref. (I) is made of PTFE or polyimide. USE/ADVANTAGE - The invention provides a simpler, less expensive method for metallising the sides of holes drilled through plastic (esp. PTFE) circuit boards, to produce a uniform metal coating in the exposed plastic surface. The repeated chemical deposition which is usually required in stage 1 can be replaced by a single sputtering treatment which takes less time to produce a layer of sufficient thickness and density for subsequent electrolytic deposition, with a defect rate (w.r.t. coverage) of below 1% (cf 5-10% for chemical copperplating). The sputter-etching pretreatment can be carried out in the same chamber, thus elimintating the need for separate chemical cleaning and etching to remove the oxide layer.

Patent DE-4311891-A1 (DE)
Title: Loading platform
Inventor: GRAAFF WOLFGANG DIPL ING
IPC: B65D90/14
Filed: 1993-04-10
Abstract: The subject-matter of the invention is a loading platform having two equal side walls located opposite each other. Each of these two side walls is, on the one hand, sensitive to pressure and, on the other hand, can be moved away or moved into an ineffective position such that the loading platform can be loaded with loading equipment, as a result of which there is a risk of the side wall which remains in its functional position and is located opposite the side wall which has been moved away or is in an ineffective position being damaged in the event of the loading equipment (e.g. fork-lift truck) coming too close. In order to counteract this risk, a spacer strip is mounted at an appropriate distance ahead of each of the side walls, which spacer strip prevents any further approach up to the side wall, possibly due to the fact that the personnel operating the loading equipment is made aware of it. Since each side wall can be the side wall remaining in the functional position and the side wall which is to be put into a non-functional position or moved away, the spacer strip in front of each of the side walls is likewise adjustable between two end positions. The one end position is the active position in which it acts in the manner described above in front of the side wall which is in the functional position. The other end position is the non-active position in which, like the side wall which has been moved out of its active position or moved away, it does not impede the access to the loading platform. The loading platform and side walls can be parts of a large container with... Original abstract incomplete.

Title: Dechlorinating and neutralising water, esp. water used in control of chlorine gas escapes - comprises passing water in closed container through optional neutral (e.g. gravel) layer and then through layers of dechlorinating and neutralising substances
Inventor: KRAUSE WILLIBALD
IPC: C02F1/66
Filed: 1993-07-19
Abstract: The water is passed in an enclosed system through an optional neutral granular material, for example a layer of quartz gravel (6), and then through granular dechlorination and neutralising substances (A) and (B), the dechlorinating substance (A) being calcium sulphite. Also claimed is a device for carrying out the procedure, consisting of a container (2), with an inlet (3) and an outlet (4), in which the treatment is effected. More than one substance (B) may be used in the form of a mixture or in separate layers. Neutralising substances (B) may consist of calcium carbonate (8), magnesium hydroxide and magnesium oxide, as separate materials or in combinations. The container may have one or more chambers for receiving the neutral material and the treatment substances (A,B). The water may pass through these chambers in series or in parallel, and may flow from one chamber to another either in an upward or a downward direction, or both. Substances (A) and (B) may be separated by layers (11) of a neutral material such as quartz gravel. The ratio of the mass of substance (A) to that of substance (B) is 1:1 to 1:6, whether they exist as separate layers or as a mixture. USE/ADVANTAGE - Used for dechlorinating and neutralising chlorine-contg., acidic water and esp. water which has been used in sprinkler systems for dealing with escapes of chlorine gas. The procedure uses stable chemical substances and can be operated by relatively unskilled personnel. It is therefore reliable, simple and economical to implement.
