Title: Transistor chain amplifier - has intermediate wire in addition to input and output wires
Inventor: MEYER FRITZ DR ING
IPC: H03F1/18
Filed: 1975-06-10
Abstract: A transistor chain amplifier has an intermediate wire supplied through current amplifying transistors connected to the input wire. It also serves as a supply wire for further voltage amplifying transistors connected to it and also connected to the output wire, as in 2363095. Gain is varied by variation of the current supplied through the intermediate wire, in the same sense. By using bipolar transistors, the amplification is given by a formula relating the load resistance of the chain amplifier, the resistance of one amplifying element and the operating current of the amplifier circuit dependent on the emitter-diffusion resistance.

Title: Lathe tool deviation compensation - has deviation measured from cutting tool inclination and position for zero point adjustment
Inventor: RINN JUERGEN DIPL ING
IPC: B23Q17/22
Filed: 1975-10-17
Abstract: A numerically controlled lathe has a method of compensating deviations of the tool position from that required, as caused by headstock (4) and tailstock (5) deformations.

Title: Preconditioning and processing crude cellulose fibres - with polyhydroxy carboxylic acid, monosaccharide and wetting agent, in aq. alkali
Inventor: NAUJOKS ELFRIEDE DIPL CHEM DR
IPC: D06M13/207
Filed: 1975-12-03
Abstract: Cellulose fibres are preconditioned nd processed by treating with (a) >=1 polyhydroxy carboxylic acid (e.g. glycolic acid) and/or salt; (b) >=1 monosaccharide (e.g. lactose); and (c) >=1 wetting agent, pref. a surfactant; in an aq. alkaline medium. The amt. of (a) used is 0.01-10 (pref. 0.1-3) wt.%; of (b) is 0.01-10 (pref. 0.1-3) wt.%; and of (c) is 0.01-2 (pref. 0.1-1.5) wt.%, (based on fibres). Treatment is at 80-150 (pref. 95-135) degrees C. for 30 sec. - 5 hr. Method gives optimal purification and brightening of fibres: (a) are better complexing agents for alkaline earths than the conventionally used polyamino carboxylic acids, and use of (b) facilitates removal of coloured impurities and prevents oxidn. of the cellulose by air. The removal of seed husks is easier, and whiteness and wetting ability of the fibres are increased. In an example, crude unbleached cotton treated with a soln. contg. 50 g./l. NaOH, 1 g./l. polyglycolether, 3.0 g./l. fructose and 3.0 g./l. Na-gluconate had a degree of whiteness 74.4% cf. that of the untreated cloth 55.4%.

Title: Reinforced concrete bridge structure - rests on two columns and has two sections moved longitudinally on columns to meet for joining in centre
Inventor: HERTLE EDMUND
IPC: E01D21/06
Filed: 1976-03-16
Abstract: The reinforced concrete bridges resting on two columns (2) are made by prefabrication principles. On each side of the area to be bridged are built a column and the balanced bridged section. These two assemblies are moved towards each other and joined for bridging in the final position. This method is used when the bridge sections cannot be rotated into final position on columns due to the obstacles. The bridge superstructure (3, 4) is completed along the bridge longitudinal axis on the upper parts of columns laterally away from the final foundation part of the columns. These superstructures are pushed longitudinally on a sliding track on the column upper parts and the column parts and bridge superstructure are joined. The overhanging parts of the bridge superstructure are supported and balanced.

Title: Volume control for radio or TV receiver - stores additional transmitted information on program and content reads out information for instantaneous programme to set volume level
Inventor: JAKUBOWSKI HORST DIPL ING
IPC: H03G1/02
Filed: 1977-04-14
Abstract: The recieved TV or radio programme signal contains additional information on the programme composition. The additional information is separated from the programme signal, and the programme signal level is adjusted in accordance with this information. When the programme signal contains additional information on the programme being transmitted, such as speech and music, and also on the change from one programme part to another, preselected values fro the sound level difference and/or correction are separately stored for the individual programme parts. The stored value for the programme being received is read out from the store and the programme signal level adjusted accordingly.
