In an insulating element (19) for structure-borne noise for the isolation as far as vibration is concerned of two structural components (2, 3) provided with receiving parts (4, 5) arranged essentially concentrically with one another, an elastic intermediate member (21) is insertable into the annular gap (6) between the receiving parts and compressible in the axial direction by means of a clamping ...

1. Process for producing cement clinkers, by which composed cement pipe powder of broken and milled raw stones is baked in a kiln, characterized in that the cement pope powder without the addition to a binding agent is pressed dry by means of specific amounts of pressure of 200 and more bar into casting with a gross density of at least 1.8 kg/dm**3, which thereafter are baked in a tunnel kiln, and...

A process of producing a peanut oil, comprising a first stage of immersing peanut seeds cleared of the skins in hot water for a predetermined period of time, cooking the resultant peanut seeds in an equal volume of hot water at a predetermined temperature under a predetermined pressure for a predetermined period of time, grinding the cooked peanut seeds into the form of slurry, diluting the slurry...

1. Process for the transmission of data signals between a central station and at least one of a plurality of data subscribers which are connected via a junction station to a common permanently connected transmission link within an envelope structured synchronous data network, wherein each data subscriber emits the data bits which are to be transmitted combined with two control bits (status bit and...

Zinc complexes of various monovalent and divalent polyether antibiotics are provided which act as coccidiostats and growth promoting agents when administered to food- producing animals such as cattle, sheep, swine and poultry. Soluble zinc salt is added to a fermentation beer containing the polyether antibiotics to form an insoluble, recoverable biomass containing the desired zinc antibiotic compl...

1. Process for reactivating active charcoal which is used in the preparation of dialkyl dicarboxylates, in particular dialkyl phthalates or dialkyl adipates, with the aid of sulphuric acid or toluenesulphonic acid as catalysts, characterised in that, after filtering-off and removal of most of the adhering dialkyl dicarboxylate by blowing in nitrogen, extracting with gasoline and subsequently blowi...

A louver type shutter for ventilation systems has hollow flaps which are pivotally mounted in a frame. Seals made from a foamed sheet material are located between the flaps and the frame and the front edges of the flaps are pressed directly into the foam sheet.

In the representation of a normal character, a delay circuit delays the activation signals (V) allocated to the individual dots of the dot matrix by a constant basic time. When an italics control signal (K) is present, the delay circuit delays the activation signals by a specific line delay time which increases from line to line by a constant amount. The increase in the line delay time amounts to ...

An electronic switch with two transistors connected in a Darlington configuration. A first of the two transistors has collector-emitter terminals connected between input and output terminals. A regulator monitors the output voltage and controls the duty cycle of a switch providing base drive current to the second transistor of the Darlington pair. Current from the switch is also provided to a seco...

A package for a stack of rectangular, plate-shaped parts, such as electronic components, comprises a tubular container having a rectangular internal cross section corresponding to the parts to be packed. The interior of the tubular container has a recess at each corner so that the parts cannot jam or block during passage through the container.

A tire with a radial carcass reinforcement and a tread reinforcement formed of at least three plies of cables is improved due to the fact that the tread reinforcement is formed of two plies of cables having a very low elongation and forming angles of 50 DEG -70 DEG with the longitudinal direction of the tire and of two plies of elastic cables forming angles of 5 DEG -15 DEG with the longitudinal...

2,3-Dihydro-2,2-dimethyl-7-hydroxybenzofuran is prepared by heating isobutenylpyrocatechol or isobutenylpyrocatechol/methallylpyrocatechol admixtures, at cyclization/isomerization temperatures, in the presence of a catalytic amount of an organic sulfonic acid.

The filter press for dewatering of materials such as, for example, sewage sludges has two sieve belts or filter belts (18, 19) being passed, with inclusion therebetween of the material to be dewatered, in common over dewatering drums (2, 3, 4, 5, 6). Behind the dumping location for the dewatered cake, the sieve belts or filter belts (18, 19) are separately returned again and tensioning rolls for a...

The invention provides impression materials for use in dentistry comprising the reaction product of (a) a diisocyanate or triisocyanate, (b) a dihydroxy compound having a molecular weight of from 300 to 10,000 and (c) an unsaturated monohydroxy compound. The invention also includes processes for preparing said impression materials.

What is described is a mechanical stop device for a floor-mounted door closer, which has a supporting member loaded by the closing-spring force and in the form of a hollow cylinder and which possesses a holding unit which is formed by a conical part guided in the hollow cylinder and coming under spring prestress and by an abutment element engaging into the hollow cylinder. An overrideable blocking...
