Patent DE-3327604-A1 (DE)
Title: Seal on a calibrating trough
Inventor: HOEPPNER FRANK
IPC: B29C48/90
Filed: 1983-07-30
Abstract: The invention relates to a seal at the outlet end of a calibrating trough which is disposed downstream of an extruder and in which hollow profiles or pipes are cooled until dimensionally stable. The sealing effect is produced by a continuous wetting of an intentionally left gap, preferably using the same liquid as that used for cooling within the calibrating trough. The continuous wetting of the gap between the workpiece and a guide ring can be carried out by liquid sprayed from nozzles or by a bath held with the aid of a casing. The waste production at the beginning of an extrusion process can be considerably reduced with the aid of this seal, in addition particularly lightweight flexible profiles and pipes can be produced according to this process which furthermore can also have a highly fissured or grooved surface.

Title: Process for the preparation of 1H-1,2,4-triazole
Inventor: THEIS CHRISTOPH DIPL CHEM DR
IPC: C07D249/08
Filed: 1983-08-10
Abstract: A process is proposed for the preparation of 1H-1,2,4-triazole, in which, in a first step, hydrazine, hydrazine hydrate or aqueous solutions thereof are reacted with alkyl formate to give mono-formyl hydrazine, whereupon, in a second step, formamide is reacted with mono-formyl hydrazine in a molar ratio of 1.0 to 2.1 per mole. After the first step, it is expedient to distil off the alcohol which has formed and at least some of the water. After the reaction, excess formamide is removed by distillation. When the reaction solution is worked up by distillation, not only excess formamide, water and formic acid are separated off but also small amounts of triazole, which are expediently recycled to the second step.
Patent DE-3329737-A1 (DE)
Title: Electronic electricity meter for two directions of energy
Inventor: STEINMUELLER GUENTER DIPL ING
IPC: G01R21/00
Filed: 1983-08-17
Abstract: The electricity meter according to the invention contains a multiplier (1) for current and voltage, a following quantizer (2), with separate counting devices (4, 5) for the two directions of energy, as well as an energy-direction discriminator (6). Different maximum currents are fixed for both directions of energy. The current input of the multiplier (1) is preceded by a switchable input signal divider (8), which is driven by the energy-direction discriminator (6). In this arrangement, the input signal of the current input of the multiplier (1) is increased in the direction of energy in which a smaller maximum current is fixed. Consequently, the measuring error of the electricity meter caused in particular by offset voltages and offset currents is reduced in the case of small currents. <IMAGE>

Patent DE-3408686-A1 (DE)
Title: Tipping plank-type trolley
Inventor: ULLMANN WALDEMAR
IPC: A21B3/07
Filed: 1984-03-09
Abstract: A tipping plank-type trolley or tipping box-type trolley to accommodate and handle pieces of dough, such as roll-shaped pieces of dough, is described. The tipping box-type trolley has a frame which can be pivoted about 180 DEG  and which accommodates a plurality of stacking units which consist of tipping boxes and a baking tray lying upside down on them, which are arranged one above the other and which enclose the pieces of dough so that the latter can be pivoted together with the frame into the overhead position in which they are baked. So that the pivoting process can be carried out, the stacking units can be clamped to the frame by means of a clamping device. The individual tipping boxes are held separately by means of guides in the frame, the distance between the said guides being larger by a predetermined untoleranced dimension than the height of the individual stacking units. Separate clamping devices are assigned to the stacking units in each case, the said clamping devices being driven synchronously and being essentially releasable abruptly and simultaneously. This tipping box-type trolley ensures simpler operation and easier manipulation of the tipping boxes and the baking trays, so that it is possible to reduce the operating time considerably.

Filed: 1985-12-14
Abstract: The invention relates to a pressure-transmission element for joints on concrete and reinforced-concrete elements, in particular reinforced-concrete pipes which are laid according to the holing principle. The technical object consists in creating a pressure-transmission element which can be formed and arranged as desired directly at the site of use in accordance with the requirements and which does not transmit increased transverse tensile stresses in the abutting area of the concrete and reinforced-concrete elements, damage to the ends of the concrete and reinforced-concrete elements being avoided during use of the pressure-transmitting element, and the said element can be produced without expensive technological processes and without the use of high-grade raw materials. According to the invention, the pressure-transmitting element consists of one or more annular or spiral layers, lying side-by-side, of a highly compressed cladded-core rope structure of round cross-section. The core material has a high resistance to deformation but a largely elastic behaviour. The rope diameter or, in the case of several layers, the sum of the rope diameters is not more than 80% of the wall thickness of the concrete and reinforced-concrete elements. The cladded-core rope structure can preferably be multi-step.

Title: Flow-rate and particle analyser and flow cell therefor
Inventor: HIRAKO SHINICHI
IPC: G01N15/14
Filed: 1986-02-07
Abstract: A flow rate and particle analyser is used to measure the optical properties of particles, suspended in a suspension liquid, by irradiating light from a light source onto the particles. It contains a flow cell (6) having a principal member (7) which consists of an essentially transparent, essentially colourless and essentially non-fluorescing material, and has an essentially planar front surface (7a) and, parallel thereto, an essentially planar rear surface (7b). A flow duct (8) is constructed in this principal member in a manner essentially parallel to the front and rear surfaces, and is situated substantially nearer to the front surface than to the back surface. The front surface of the principal member faces the light which impinges on the particles in the suspension liquid flowing in the flow duct. As a result, a lens assembly (15) can be brought very close to the flow duct by arranging it very close to the front surface of the flow cell, it being possible in this way to achieve a relatively large numerical aperture so that the incoming and emitted light bundles can be effectively concentrated and collimated. Furthermore, there is no need for a large quantity of immersion oil (23) between the lens assembly and the front surface, and so difficulties in manipulation are avoided. Furthermore, a light source (9) of relatively low intensity ... Original abstract incomplete. <IMAGE>
