Patent DE-2813998-A1 (DE)
Title: Transversal filter for programmable network - has charge-transfer shift register reading out serially to form filtered output
Inventor: KNAUER KARL DIPL ING
IPC: H01L29/768
Filed: 1978-03-31
Abstract: The filter employs a charge-transfer device as shift register (4) with parallel inputs (2). The weighting coefficients are generated by reading in signal-dependent quantities of charge using weighting circuits (81-83). The charge levels attained by summing in the register are read out serially to construct the filtered output signal. To allow the weighting coefficients to be set electronically over a relatively wide range the weighting circuits are provided with source zones (D1-D3). These are controlled/selected separately or with additional source zones located in pairs on opposite sides of the CTD transfer channel or with transfer gates between the weighting circuits and the register. (The transfer gates have gate-oxide and field-oxide zones). The weighting coefficients can be varied over a range of 1:1000 without requiring the filter to occupy a large area. This wide variation increases the applications for the filter, which is primarily for use in an electronically programmable filter network.

Title: Command decoding circuit - has two counters, connected to signal input, which determine AC voltage zero crossings and are reset by half-waves present
Inventor: NUTZ KARL-DIETHER DIPL ING
IPC: H02J13/00
Filed: 1978-08-16

Title: Carbon di:oxide laser with resonator chamber - is designed to provide emission with frequency shift to increase output power through window
Inventor: SCHALL WOLFGANG
IPC: H01S3/223
Filed: 1979-01-10
Abstract: A carbon dioxide laser is designed to produce a frequency shifted emission that enables the output power to be in excess of 100W for longer than 1 msec. The active laser gas flows through a channel (1) with resonator mirror (3) inset into one wall and transparent window (5) in the other wall. A chamber (6) is side mounted and contains a partially reflecting resonator mirror (8) two heating elements (9) and a controlled inlet (13). The active carbon dioxide gas flows through the channel at a temperature of 240 deg.F. The inactive carbon dioxide gas is admitted to the side chamber and is heated. The active gas flow passing between the mirror (3) and the window (5) induces a laser emission that interacts with the side chamber. The established resonance produces an emission with a slight frequency shift.

Title: Metallothermic prodn. of magnesium - using aluminium silicon alloy reductant and magnesia calcium oxide oxidant giving liq. silicon aluminium alloy by=product
Inventor: KIBBY ROBERT MILTON
IPC: C22B26/22
Filed: 1980-01-24
Abstract: In the metallothermic prodn. of Mg by reaction of an Al-Si alloy reductant with an oxide mixt. contg. MgO and CaO, in the presence of a molten Ca aluminate slag, and recovery of Mg vapour, the improvement is that MgO is present in the oxide mixt. in less than the stoichiometric amt. to consume the Al of the Al-Si alloy so that a lower Ca-Mg-aluminate slag layer and an upper spent Al-Si alloy layer are formed, the Al-Si alloy being (periodically) tapped off as a by-product. The process results in a liq. Al-Si alloy by-prod. which may be used to produce a Si alloy prod. by addn. to Al. The presence of Si reduces the amt. of Al vapours evolved allowing prodn. of relatively pure Mg (cf. Us 3782922) without sacrificing the reactivity qualities of Al reducing agents.
