Title: Process for the preparation of a niobium solution for the preparation of high-purity niobium oxide
Inventor: ECKERT JOACHIM DR
IPC: C01G33/00
Filed: 1982-11-12
Abstract: The title process is a preocess for preparing a niobium solution for the preparation of high-purity niobium oxide by precipitation of hydrotal niobium oxide from a niobium solution and calcination, and involves producing a hydrofluoric and sulphuric acid crude solution predominantly containing niobium compounds and, in addition, inter alia, tantalum compounds and extracting this solution by using TOPO dissolved in kerosine. The crude solution is extracted with a solution of TOPO in aromatic kerosine, and the loaded organic phase is washed in one or several steps with dilute sulphuric acid. The niobium is then stripped from the purified organic phase using water, and this niobium solution is freed from tantalum using unloaded TOPO, in which the tantalum is removed from the stripped organic phase and residual niobic acid is removed by additional stripping using an ammoniacal NH4F solution. <IMAGE>

Title: Apparatus for waste water purification by anaerobic fermentation
Inventor: MAEAETTAE RAIMO
IPC: C02F3/28
Filed: 1983-01-26
Abstract: An apparatus for purification of waste water by anaerobic fermentation is composed of a closed vessel (1) equipped with means (2, 10) for feeding the waste water to be purified into the vessel, means (5, 6, 3) for discharging the purified water, the gas and the sludge from the vessel, means (4) for mixing the vessel contents and means (7) for separating the gas in the upper part of the vessel. In a departure from conventional reactors having complete mixing, the vessel (1) is subdivided by a filter (8) into two compartments located one above the other, which filter (8) contains a filling acting as support for the methane bacteria, having at least one filler and a sludge layer and suspended particle layer above it, the stirring means (4) being arranged beneath the filter, the means (2, 10) serving to feed the waste water to be purified opening beneath the filter (8) and the means (5, 6) for removing the purified water and the gas being connected to the vessel compartment located above the filter (8). In this manner, a cheap and simple apparatus for purifying waste water has been created in which no substantial mutual mixing of acid and methane bacteria can occur. <IMAGE>

Title: Partition pipe for a cattle stall
Inventor: SPINDER TJIPKE
IPC: A01K1/00
Filed: 1983-05-13
Abstract: Conventionally, a partition pipe is anchored in or on the stall floor by at least two pipe feet which are arranged at a mutual spacing. In the construction of the stall floor, preparatory measures are consequently necessary for each foot. These measures can be at least halved by the use of a partition pipe according to the invention, which has a loop-shaped design, is fastened to the stall floor with only one compact foot and is arranged in a suspended position above the stall floor. On the one hand, the assembly work is reduced to half the time, and on the other hand the stall floor is kept free of a second partition pipe foot so that stall work is easier.

Title: Process for the dyeing of textile sheet-like structures
Inventor: WOLF ADOLF
IPC: D06B5/22
Filed: 1983-05-21
Abstract: The invention relates to a process for the dyeing of textile sheet-like structures. Web-shaped sheet-like structures to be dyed are wound onto a perforated tube. The dye liquor is subsequently forced into the tube, penetrates into a roll and flows through this. According to the invention, during the winding, a perforated, for example screen-like web element is fed in parallel with the textile sheet-like structure to a winding station and is wound on the tube together with the sheet-like structure to be dyed. This gives rise, between the individual roll layers, to cavities which improve the throughflow capacity of the sheet-like structure to be dyed.

Filed: 1983-07-26
Abstract: A structure (1) carries a platform (2) and a base frame (3) on which a motor (4) with gearing (5) is arranged for a rope drum (6). On one end, the rope drum (6) has, in addition to the rope groove (8), a flanged sheave (7) and, in front of the latter, a rope-lifting wedge (9) which lifts the rope (11) over the position lying in the rope groove (8). During further rotation of the rope drum (6), a reversal wedge (10) adjustably fastened to the flanged sheave (7) by means of screws lays the rope in the opposite direction to the rope grooves, and during every revolution of the winch drum it is pressed further by the rope already wound. The winding of the rope (11) is assisted by a rope guide (17) which, during rotation of the rope drum, moves parallel to the winch drum (6) approximately in accordance with the pitch of the rope groove (8). The rope guide (17) is mounted between two adjacent roller chains (24) by means of a pin (23), which at the same time is the pivot as a connecting member between between the link plates of roller chains (24). Fastened to the spindle (12) of the winch drum (6) is a chain wheel (13) for a chain (14) which transmits the rotary movement of the winch drum (6) to a drive mechanism (15), the deflection chain wheels (25) of which drive the roller chains (24). <IMAGE>

Title: Test round and/or practice round for an artillery weapon
Inventor: GAMPE EGON
IPC: F42B8/12
Filed: 1984-01-11
Abstract: A test round and/or practice round for an artillery weapon, especially in accordance with Patent 3,225,984, whose driving-band segments, which are arranged in an insertion element, can be pushed out as far as the driving-band diameter with the aid of a pull rod, and can be unlocked for extraction of the round from the gun barrel, is intended to be improved to the effect that not only the unlocking, but also the insertion of the driving-band segments into the interior of the insertion element takes place in a positive manner, so that, after unlocking, the round can be pulled out of the barrel with the pull rod, without using further aids. As is shown in Fig. 1, this is achieved in that the driving-band segments 4, which consist of the parts 9, 10, are pressed against a stop 8 in the interior of the insertion element 2 by rotating a clamping part 7, which is arranged centrally in the insertion element 2 such that it can rotate, in one rotation direction over a sliding element 18 which in this case can be displaced axially by the clamping part 7, and are thus fitted on the driving-band diameter. In order to unlock and extract the round, the driving-band segments 9, 10 are drawn into the interior of the insertion element in a positive manner for unlocking, by rotating the clamping part 7 in the opposite rotation direction and hence displacing the sliding piece 18 in the opposite axial direction even if the driving-band segments should be locked. Said unlocking is achieved even when the round is thought to be stuck. The round can now be pulled out of the barrel using a pull rod which can be attached to the clamping part 7. <IMAGE>

Such a diode oscillator is to be constructed in such a manner that it can be continuously tuned over a wide range with a simple mechanical structure. For this purpose, the invention provides that the inner conductor (3) has an inner conductor part (2) which can be axially moved in a central hole at the line-side terminal of the diode (1). A pretensioned spring (4) arranged in the inner conductor (3) is used for pressing the inner conductor part (2) against the diode (1) and the inner conductor (3), which is carried to move in a hole in the outer conductor (5), with an outer step against a stop (11). This stop (11) can be axially displaced by means of a tuning device (12) arranged in parallel with the coaxial line in a hole. <IMAGE>
