Title: Process for recovering pure 1-nitroanthraquinone from a mixture of anthraquinone with its nitration products
Inventor: BAYER HELMUT DR
IPC: C07C201/16
Filed: 1983-06-24
Abstract: In the process described, anthraquinone is nitrated in a known manner, for example using highly concentrated nitric acid, the nitration according to the invention being stopped when ten or less per cent, preferably only one to two per cent, of dinitroanthraquinone are present. The unreacted anthraquinone inevitably obtained in this process is removed according to the invention by means of a carrier gas distillation, preferably by means of superheated water vapour at 200 DEG C, and the residue is broken down by three simple vacuum distillations into a total of four final products; the main product is 1-nitroanthraquinone, which is obtained in high purity and a yield of 70% of theory. Instead of separation by subsequent vacuum distillations, removal of the 1-nitroanthraquinone can also be carried out by solvent crystallisation. The process according to the invention avoids high dinitroanthraquinone concentrations which give rise to explosions; the process is economical as a result of recycling of the unreacted anthraquinone.

Filed: 1983-12-14
Abstract: The invention is in the technical field of equipment for injection moulding, but in particular it relates to a mould for producing a bucket provided with a handle in the assembled position. The technical problem to be solved is that of designing a mould which is not only efficient and capable of ejecting the finished injection moulded parts precisely, but which also permits a bucket and a corresponding handle to be produced in one operation, which, although they are independent of one another, are virtually already assembled, so that further work of joining can be avoided. The problem is solved by a mould in which the cavity and the mandrel are counter-shaped to one another so that a conical container is described, provided with a first edge section extending substantially transversely to the axis of the mandrel and a second section having an edge turned over with respect to the first section, and in which the cavity and the mandrel have plate-like surfaces directed towards one another and provided with mutually opposite depressions, which extend in such a manner that they describe a handle for the aforementioned conical container and in which the aforementioned depressions are connected with the aforementioned container in regions diametrically opposite to the aforementioned edge, channels being formed which open into cavities, which ...

Patent DE-3407558-A1 (DE)
Inventor: VOLZ HANS DR RER NAT
IPC: G02B6/134
Filed: 1984-03-01
Abstract: On a substrate (1) comprised of a lithium niobate single crystal, there is applied an oxygen-inert diffusion barrier, for example in the form of a platinum layer (2), wherein is etched the desired strip pattern structure (6). A titanium layer (7) is then applied, before heating in a diffusion oven in the presence of an oxygen atmosphere. Thus, the titanium diffuses along the strip pattern structure (6) in the substrate wherein it forms an optical channel (8) wherein the light may be retarded and this by the action of an electrical field. The titanium surface is oxidized by heating in the presence of oxygen. The platinum strips (10, 11) remaining along the optical channel (8) form self-adjusting contacts for applying the control voltage.
Patent DE-3407749-A1 (DE)
Title: Heat pump having a refrigerant circuit
Inventor: HORSTMANN CLAUS DIPL ING
IPC: F25B27/00
Filed: 1984-03-02
Abstract: In heat pumps whose refrigerant circuit works in a large range of condensation and evaporation temperatures, for the purpose of obtaining in by far the most operating states a good utilisation of the motor in the favourable range of efficiency and thus of optimising the calorific value of the heat pump, a loss-attended intervention in the refrigerant circuit is undertaken in the unfavourable operating states working at high evaporation and condensation temperatures, these extreme operating states being insignificant for the annual calorific value. This is performed by arranging in the suction line a restricting element which influences the refrigerant mass flow and is operated as a function of a prescribed characteristic of the refrigerant circuit. This restricting element is adjusted by an actuating signal at high evaporation and condensation temperatures, thus resulting in a pressure drop from the evaporation pressure to the compressor input pressure, and this corresponds to a reduction in the load adsorption of the compressor. A good utilisation of the motor during by far the longest operating period of the heat pump is achieved by means of this measure, the motor working in the range of high efficiency. This also means that the drive motor can be designed to be substantially of lower output with respect to the conventional drive units.

IPC: H03D9/06
Filed: 1985-04-12
Abstract: In a low-noise microwave mixer with only small conversion losses and with two non-linear components (D1, D2), each of which is connected to a strip line (L1, L2) which feeds a mixer input signal (S) and an oscillator signal (O) to the respective non-linear component and whose connection arms which are not connected to the two strip lines (L1, L2) are jointly contacted with a line (AL) on which the mixing product (ZF) can be tapped, at least one dielectric resonator (R) is connected between the two strip lines (L1, L2). The phase relationships of the input and oscillator signals (S, O) which are fed in the strip lines (L1, L2) past the resonator are such that the oscillator signal does not activate the resonator, whereas the input signal causes the resonator to resonate. The size of the resonator (R) is determined in such a way that, when resonating, it reflects the image frequency but does not affect the signal frequency (Fig. 2). <IMAGE>
