Title: Vorrichtung und verfahren zum leistungsabgleich eines oszillators
Inventor: WALTER THOMAS
IPC: G01S13/931
Filed: 2003-10-24
Abstract: Es ist daher Aufgabe der vorliegenden Erfindung, eine Vorrichtung zum Leistungsabgleich eines Oszillators im Hochfrequenzbereich anzugeben, welche über eine reduzierte Anzahl an Bauteilen und/oder über kostengünstigere Bauteile verfügt. Weiterhin soll ein Verfahren zum Leistungsabgleich eines Oszillators angegeben werden, welches die Nachteile der bekannten Verfahren, also die Bestimmung der Ausgangsleistung des Oszillators über ein zusätzliches, wertiges Bauelement, eliminiert. Dazu wird der Eingang (31) des Steuermoduls (40) mit dem HF-Schalter (bestehend aus (22) und (24)) elektrisch verbindbar und der Ausgang (34) des Steuermoduls (40) mit dem HF-Schalter und/oder dem Verstärker elektrisch verbindbar ausgeführt. Wird der HF-Schalter nun nicht mit einem Eingangssignal (Puls oder Gleichspannung) beaufschlagt, sondern am Steuereingang (30) des HF-Schalters die Spannung gemessen, erlangt man die erforderliche Regelgrösse (HF-Ausgangsleistung), da die PIN-Dioden des HF-Schalters die anliegende HF-Leistung gleichrichten und eine proportionale Gleichspannung erzeugen.

Title: Condensation of ketones
Inventor: MIZUTANI YUKIO
IPC: C07C45/74
Filed: 1968-12-06
Abstract: Condensation to di-, tri- or polymer cpds. is effected by heating at 60-300 degrees in the presence of Ti, Zr, Hf, or Sn phosphates as catalysts. Suitable ketones are (a) of the same or different kind with at least one H atom on one or both of the 2C atoms adjacent to the CO group, or (b) one ketone with at least 2H atoms on one or both the C atoms adjacent to the CO group and one ketone which has no H atom on these adjacent C atoms, e.g. acetone, Et2CO, Me-Ey-CO, and Me-iBu-CO). Dimeric condensation products are selectively produced at 60-160 degrees (pref. 60-130 degrees C) by operating in a liquid phase. Thus acetone yields mesityl oxide, which becomes the starting material for Me-iBu-CO, which is an excellent solvent.

Title: Mfg a container by winding fibre-reinforced material
Inventor: CHRISTENSEN GEB JENSEN BIRTE
IPC: B29C53/60
Filed: 1969-03-15
Abstract: Prodn. of a container from fibre-reinforced material comprises winding wetted threads or strips around a mandrel rotating around an axis passing through its centre, the mandrel being also rotated at an angle of 60-90 deg. during winding around a second axis, which also passes through the centre of axis and is perpendicular to the rotational axis. Winding is carried out with the aid of a thread or strip guide which revolves in a path around the mandrel.

The process enables a large sized container, such as are oil tank, to be produced in a single uninterrupted working operation. The container has only a single opening formed by the connecting element of the mandrel, which can be subsequently.

Title: Etching copper/copper alloys process - using a regenerative soln contg ammonium and chloride ions
Inventor: HAAS RAINER
IPC: C23F1/34
Filed: 1971-03-08
Abstract: The etchant is an ammoniacal soln. contg. chloride ions. The copper cpd. formed during etching is regenerated by adding a chloride e.g. HCl, NH4Cl, NaCl or similar and an ammonium cpd. e.g. NH4OH/NH3 such that the etchant retains a pH of about 8.5-10.0. The ratio of copper to etchant is maintained by adding a liq. e.g. water. The additions are made either as a function of the pH, the redox potential, specific wt. or colour change of the etchant. The molar ratio of the ammononium cpd. to the chloride cpd. is 1:2. These additions may be made either directly to the etchant or via a regenerating plant. This plant is ideally a reaction vessel above which are situated three vessels contg. the additives and the water linked to the reaction vessel by pipes. Measuring devices control the additions by measuring the redox potential, the specific wt., and colour change. Another device placed after the reaction vessel controls the density of the etchant and also its copper content and the additions.

Title: Hot machining arrangement for machine tools - hardness of material is reduced and machining speed is increased
Inventor: STRAKATA JOSEF
IPC: B23P25/00
Filed: 1973-10-01
Abstract: The arrangement consists of a mounting and guide for the burners, a mechanism which maintains the distance between the burners and the workpiece and the burners with their equipment to maintain a constant temperature at the place where the material is cut. The strength of the material is locally reduced by the burners and a higher cutting speed and faster feed-in can be used. The maximum temperature to which the material is heated is below the temperature at which structural alterations occur in the material. The material is cooled slowly in still air and recovers its original strength. Final machining and machining to good surface finish is carried out after the material is cooled down.
