Title: Process for recovering aluminium hydroxide from spent pickle liquors - by pptn. with an acid, coagulation and removal of water
Inventor: REUTER GEB LEINEN AGATHE
IPC: C01F7/141
Filed: 1974-04-22
Abstract: Al hydroxide, which is present in spent alkaline pickle liquors as aluminate, is recovered by treating the spent alkaline pickle liquor with an acid using a spent acid soln. to give pH value of 11.5-12.8, pref. 12.2-12.4, so as to half neutralise the soln. Al hydroxide is precipitated as sludge and the remaining alkaline soln. is decanted and returned to the pickling bath. Neutralisation is completed by further addns. of acid and, if required, the Al hydroxide sludge is diluted with water so that the Al conc. in the mixt. is 30-60 g/l. The Al hydroxide is coagulated by adding 0.05-0.2 g of an acrylic acid-acrylic acid amide copolymer (acrylic acid fraction 10-30%, spec. viscosity 1.6-1.9) per litre of Al hydroxide mixt. The water is finally drained from the coagulated product by filter presses. Spent acids use for the nuetralisation are pref. spent anodising solns. from the electrolytic oxidation of Al.

Abstract: A signature opening system for removing signatures from a stack and delivering them in an open state to a V shaped saddle for feeding to e.g. a bookbinding machine, has a feed conveyor which pushes the folded signatures into the space between two conveyor belts forming a conveying path which is nearly a complete circle, each signature being carried round the path by a mechanism with a finger which engages the rear, and with a carriage which carries rollers which engage circular cam tracks so that a suction head is forced against the upper surface of the signature, while the carriage itself is angled so that the upper surface is raised as the signature travels, until finally the opened signature falls vertically over the saddle at the end of the track.
Patent DE-2425757-A1 (DE)
Inventor: ROTTIER MARCEL
IPC: G06F11/273
Filed: 1974-05-28
Abstract: The disclosure described improved apparatus for testing a data processing system including first and second functional members. First and second microprograms for testing the first and second functional members, respectively, are held in a read only store. If an error is detected in the first functional member while the data processing system is processing data, a circuit transmits the starting address of the first microprogram to an address register for the store, so that the first microprogram tests the defective first functional member. As the first functional member is tested, the symptoms needed to diagnose the defect are collected. If the first microprogram is completed without all of the symptoms required for diagnosis being collected, another circuit transmits the first address to the address register so that the first microprogram is executed again. The first microprogram continues to be executed until all of the symptoms needed for diagnosis are collected. The same procedure is used for the testing of the second functional member.

Title: Picture reproduction improvement cct - used when three-line sequential colour signal is converted into non-sequential signal
Inventor: HARTMANN WERTHER
IPC: H04N9/86
Filed: 1974-07-10
Abstract: The picture improvement circuit comprises gates for at least partial suppression of the colour signal in the non-sequential colour picture signal when the difference between colour signals spaced by a period of three lines exceeds a specified value. The signals are generated using delay lines provided for recovery of a non-sequential colour picture signal. The gate can be operated also by an additional recognition circuit for brief signal drop-outs. The effectiveness depends upon the fact that a black and white partial substitution is less disturbing to the viewer than false colouring. A clear black and white signal appears at the output (14) when necessary to prevent disturbing horizontal or diagonal colour fringes appearing.
