The invention relates to a regulating arrangement in particular on packing machines for the feed of weblike packing material in register with decorations or folding indications, so-called crease lines, present on the web. In accordance with the invention the desired control is obtained by regulating the tension of the web with the help of a guide roller over which the web is passed. The speed of t...

A foamable and simultaneously curable polyester composition is provided. The composition consists essentially of the following (all being in parts by weight): (a) 100 parts liquid unsaturated polyester resin, (b) 0.5 to 10 parts monosubstituted sulfonyl hydrazide having the formula RSO2NHNH2, wherein R is C1-C12 alkyl, C5-C6 cycloalkyl, C7-C10 aralkyl, phenyl, naphthyl, or phenyl substituted with ...

Storage-stable, discrete free-flowing flakes of a hydrophilic or water-soluble polymer gel, such flakes comprising a thin adherent film coating of a processing aid powder, are facilely produced by comminuting a larger shaped article of said polymer gel, e.g., a block, sheet, strip or layer thereof, in the presence of said processing aid powder, and said powder being present during comminution in a...

3-[(Z)-1-Propen-1-yl]-7-acylamido cephalosporins in which the 7-acyl group is phenylglycyl or substituted phenylglycyl are orally active antibiotics against Gram+ and Gram- bacteria.

A conditional replenishment video data transmission system involves the transmission of updating digital data for clusters of consecutive picture elements, all or most of which show a change since the previous frame, in lines of a raster over an image to be transmitted. The lines of the raster are numbered cyclically in groups of 8, the numbers being part of line synchronizing code words, and the ...

An integrated circuit is provided with shielding means to protect it from bombardment by alpha particles and other ionizing radiation, so as to avoid errors in the functioning of the integrated circuit by the sudden introduction of electrical charge attendant upon the incidence of such radiation. The shielding means is in the form of a semiconducting layer, of the type of material which itself mig...

A multi-component grouting system having at least one component wherein the active ingredient is contained in the dispersed phase of a water-in-oil emulsion, the oil providing an effective barrier against mixing of the components thereby enabling the components to be stored indefinitely in direct contact. The components may advantageously be encapsulated in a single compartment frangible casing fo...

The plant has a fish tank and an outfall. The fish tank is designed as an oxidation drain in the waste water sense, which is set up for a residence time of the elutriation water of less than ten hours, preferably about two hours. Between the oxidation drain and outfall, there is an activated sludge purification tank. In this, on the one hand a nitrification takes place and on the other hand a deni...

In the process, it is proposed according to the invention that one or more hydraulic binders of high fineness, in the case of cements of at least 6000 Bains, are added to the sludges in an amount sufficient for their spreading and drying and the product is obtained by crushing the dried mass.

The device for assembly and disassembly of the side sealing chains (8, 9) on double mould lines (3) having an upper and a lower sheet belt for foam filling of sandwich building elements has a device (14) for inserting and removing the chains (8, 9) combined with a chain magazine (15). On one side of the double mould line (3) a chain magazine (15) is disposed parallel thereto to receive and deliver...

A method of combating ectoparasite (especially acaricide) and helminth infestations in animals, especially sheep and cattle, which comprises treating said animals with an effective amount of a compound of the formula: where (R<1>)m represents up to 4 optional substances, m being 0 or an integer of from 1 to 4, each R<1> independently being C1 C4 alkyl, C1-C4 alkoxy, C1-C4 alkylthio, halo,...

Apparatus for automatically laminating photoresist dry film (52) onto each of a plurality of panels (63) stacked upright in a panel feed unit (16) with a 10 DEG slant counterclockwise from the vertical, the film being easily contaminated, limp and tacky, although peelable, thereby enabling the use of a polyethylene protective coating, includes a film feed bar (28) for pulling the film from a roll...

The short switching times of gate-turn-off power semiconductors, particularly in DC choppers, lead to high turn-off overvoltages even with low line inductance of the circuit and to high power losses in the damping resistor in the case of conventional RCD circuitry. It is intended to limit the turn-off overvoltage and at the same time keep the losses low. For this purpose, an additional protective ...

A control system for an internal combustion engine having a fuel injection nozzle which is connected via a fuel line to a fuel injection pump so that fuel forced out of the fuel injection pump is conducted via the fuel line to the fuel injection nozzle and is then injected into an engine via the fuel injection nozzle. A valve member is movably disposed in the fuel line to allow the fuel to pass to...

In a timing control device of a fuel injection pump which is so arranged that the fuel injection timing is adjusted in accordance with the duty ratio of a driving pulse signal applied to a timing valve, the frequency of the driving pulse signal is controlled in response to data showing the rotational speed of the fuel injection pump in such a way that the resonating phenomenon does not occur where...
