Title: Process for the preparation of anthrimides
Inventor: FLOHR HELMUT DR
IPC: C09B3/10
Filed: 1983-07-13
Abstract: Process for the preparation of anthrimides in a one-pot reaction in which   a) leuco-1,4-diaminoanthraquinone is oxidised in nitrobenzene to give 1,4-diaminoanthraquinone, b) the diamine obtained is monobenzoylated at 33 to 39 DEG C in the presence of 0.8 to 1.2 % by weight of water and acid-binding agents and c) the 1-amino-4-benzoylamino compound obtained is condensed with an aromatic halogen compound in the presence of copper to give the anthrimide. During the benzoylation, an aminobenzoylaminoanthraquinone is obtained which contains less than 3 % by weight of starting material and of the bis-benzoylamino compound. In the carbazolisation, the anthrimides obtained by the process yield vat dyes which have the same properties as the dyes of the prior art. h

Title: Device for checking and adjusting the roll build-up on a warp beam
Inventor: BOEHM ALFRED DIPL ING
IPC: D02H13/18
Filed: 1984-02-07
Abstract: Device for checking and adjusting the roll build-up, formed by a yarn set of warp yarns guided next to one another, on a warp beam having lateral flanges for warping machines. Both the width of the yarn set and its relative position in relation to the warp beam are determined by means of a warping reed. Arranged at the two ends of the roll are measured-value transmitters which transmit as a function of the respective roll diameter a measured value influenced by the roll diameter. Moreover, there is provided least one desired-value transmitter which is influenced in the same way by the roll diameter and which is arranged next to the measured-value transmitters towards the inside and generates a desired value which is compared with the measured values transmitted by the measured-value transmitters, in order to generate a respective differential value in the event of a deviation between the desired value and measured value. The two differential values thus generated are then linked to one another in such a way that, in the event of identical differential values, the warping reed varies the width of the yarn set and/or, in the event of varying differential values, the warping reed displaces the yarn set.

Title: Sintered contact material and method for the preparation thereof
Inventor: SCHREINER HORST PROF DR
IPC: B22F1/12
Filed: 1984-02-14
Abstract: The invention relates to a sintered contact material of silver with at least two metal oxides and to a method for preparing it. For use in low-voltage switch gear in power engineering, contact materials based on silver are being developed more widely, in which the CdO, which had been used conventionally, is replaced by other metal oxides, for example SnO2 or ZnO and other base metal oxides. According to the invention, the microstructure of such a material comprises alternate regions with finely segregated mixed oxides in the silver metal base and adjacent regions with coarsely segregated oxides of the base metals, the distinct microstructure regions having the same average composition of base metals. Starting materials which can be used in the preparation method according to the invention may either be an alloy powder of silver with at least two base metals or, in addition to the alloy powder, silver powder and further metal oxide powders. At least part of the alloy powder in the process is internally oxidised in an appropriate temperature region so as to produce fine segregations. Coarse segregations of the metal oxides can result either from internal oxidation of metal powder in a higher temperature range or directly by mixing silver powder with the further metal oxide powders of the same composition. By mixing of the powder batches and compaction, sintering and postcompaction it is possible, for example, to ... Original abstract incomplete. <IMAGE>
Patent DE-3411008-A1 (DE)
Title: Tread crank for bicycle
Inventor: ZSCHERNITZ GUENTHER
IPC: B62M1/36
Filed: 1984-03-24
Abstract: The present invention has the object of making better use of the human energy for driving the bicycle in order to save energy. On consideration of the angle at which the foot of a cyclist presses on the pedal, it can be recognised that in the lower third of the downward movement of the crank this angle which is formed between the leg and crank becomes increasingly acute. In the lower dead-centre point, the movement is normally braked, only the momentum of the weight of the leg overcomes this dead-centre point since the leg can no longer apply energy to the crank in order to move it. If, according to the invention, the straight shape of the crank is however angled, whether to a greater or lesser extent, the leg acts on the crank at a different angle. The braking downward movement in the lower third becomes a flowing, in fact almost entraining movement downwards beyond the lower dead-centre point so that after the dead-centre point is overcome energy is still applied to the crank.

Patent DE-3420815-A1 (DE)
Title: Electronic metering unit for metering extremely small amounts of solvent at high pressure by means of a virtually inertia-less micro-metering valve, a solvent-independent flowmeter system and a low-axial-delay measuring section
Inventor: KAGE ANDREAS DR
IPC: B01J4/02
Filed: 1984-05-30
Abstract: In flow technology - for example in liquid chromatography - it is sometimes necessary to meter very small solvent flows which are at high pressure. The micro-metering valve to be patented provides, in combination with the solvent-independent thermal-pulse measuring system to be patented, a possibility to meter a solvent stream rapidly and virtually without inertia. The micro-metering valve comprises a passive valve system whose locking direction is opposite to the flow direction. A piezo-resistive element seals said valve system completely as a result of being deflected in the counter-flow direction. By controlling the deflection of the piezo-resistive element, it is possible to effect a change of the flow resistance of the micro-metering valve and thus metering of the liquid stream. The appertaining flowmeter system, which is based on a measurement of thermal pulses, comprises, as the thermal pulse emitter, a PELTIER element which generates a steep temperature gradient by active cooling prior to the thermal pulse, without supplying an unduly large amount of heat to the solvent even if pulses follow each other rapidly, since the mean amount of heat of the solvent is altered to only a disproportionately small degree compared to the temperature rise of the pulse. A low-axial-delay measuring section in the high-pressure range between the thermal pulse emitter and the thermal pulse sensor system results in the temperature gradient generated being maintained.

Title: Device for mounting boards, for example printed-circuit boards, on a carrier
Inventor: EIBEN MANFRED
IPC: H05K7/14
Filed: 1984-09-21
Abstract: Retaining devices for boards, especially for printed-circuit boards having electronic components, must guarantee that the boards on the one hand can be quickly and easily inserted and removed and on the other hand are supported securely in such a manner that even components which have a relatively high mass can be arranged on the printed-circuit board without having to worry about the printed-circuit board becoming detached or destroyed by vibration. The invention is based on the object of reducing even further the price of retaining devices for replaceable boards, in comparison with known retaining devices, and of simplifying their installation and dismantling. This object is achieved in that the retaining device has two bends (3, 4) on whose inner walls (5, 6) there are provided mutually opposite grooves (7, 8), of U-shape construction, for holding the boards (9), of which grooves at least the one (8) is provided with a sprung base surface (14) and with a sprung side limb (15) in order to hold the boards (9) without play. In consequence, it is made possible for the boards (9) to be supported without play in a retaining device, it being possible to carry out installation and dismantling without any auxiliary tools. The retaining device according to the invention is distinguished by a very simple construction. <IMAGE>

Title: Magnetoinductive measuring system for determining the surface state of metal parts
Inventor: LORENZ FRIEDRICH PROF DR
IPC: G01B7/02
Filed: 1984-10-25
Abstract: A magnetoinductive measuring system which comprises a sensor and circuitry permits non-destructive determination of the surface state of coated or uncoated metal parts. Depending on the state of the magnetic circuit of the sensor and the choice of frequency, typical changes in the resonant-circuit parameters formed by the sensor and a capacitor arise in each case, so that a statement can be made regarding sometimes very different parameters which characterise the state of metallic surfaces or detect state changes. The measured data obtained permit inferences from the state of the surface to the state of the metal part as a whole.

Title: Ventilating device, preferably for a flat roof
Inventor: HERMENEIT KLAUS-DIETER
IPC: E04D13/14
Filed: 1984-11-24
Abstract: In the course of a flat-roof renovation, a build-up ring is necessary in order to maintain the minimal distance between the upper edge of the dome light and the mounting ring. The build-up ring 1 according to the invention comprises a frame 4 which is formed of angle strips 5 and on the outer sides of which an insulating core 8, produced from a wooden material, is fixed by means of an adhesive layer 7. To protect against weathering, the insulating core 8 is coated on the outer sides with a laminate. According to the size and shape of the build-up ring, the frame 4 can be adapted to the latter. It is particularly cost-effective to use angle strips consisting of PVC. The particular advantage of the build-up ring is that moulds are not necessary for production. The fabrication of moulds presupposes mass production which cannot, however, be expected particularly in the case of roof renovations. <IMAGE>
