The removal of sticky contaminants and/or ink particles during the production of recycled paper is accomplished utilizing a hydrocyclone (31) froth flotation process. Paper having sticky contaminants from labels, tapes, hot melts, and other tacky substances, and/or print, is reduced to a finely comminuted liquid solids suspension of about 1-4% consistency (preferably over 2%). The suspension is in...

Stable aqueous dispersions of zein which may be used as controlled release coatings of pharmaceutical, animal, health, or food products in an inorganic solvent-free environment are disclosed, as well as methods for preparing the same.

A liquid hydrocarbon feedstock is formed into a first annular flow and a nozzle pressure applied of 2.1 x 10<4> Pa to 2.1 x 10<5> Pa (3 to 30 psi) above the pressure in a catalytic riser conversion zone. The liquid feedstock annular flow is impacted by both a first axial flow of atomizing gas at an impact angle of 5 DEG to 45 DEG and a second annular flow of atomizing gas at an impact angle of 1...

A circuit, for monitoring and controlling parameters of an electrosurgical unit, ESU, relative to load and the RF energy, has a load responsive output sensing circuit that measures the ESU load. A signal modifier, attached to the sensing circuit enhances the signals measured and transmits them to a buffer. An analog to digital converter, A/D, digitize the signals and samples wave pulse train at ab...

The metal atom of the organic metal-raw material is a metal selected from Pb, Ti, Zr and alkaline earths. The material is a cpd., in which the metal atom is coupled via oxygen atoms to the organic gps.. ...

The invention relates to a method for cleaning smooth surfaces such as plastic, glass and coated or uncoated metal surfaces. According to the invention, this is achieved by firstly blending air and detergent homogeneously in a dispenser, after which the homogeneous mixture obtained is combined, in a spraying device, with water. The aqueous mixture thus produced is sprayed under pressure in turbule...

The application relates to a method for the immobilisation of organic contaminants in waste material, said method being directed in particular at the treatment of organochlorine and organophosphate pesticides which are difficult to decompose and which are contained in waste material, which material may be inadequately encapsulated by the known immobilisation processes. According to the invention, ...

The invention relates to a system and a process to purify (treat) nitrogen-containing waste water by biological nitrification and denitrification. The system consists of at least two largely separated reactor compartments, a liquid inlet and a liquid outlet, the first, aerated reactor compartment being provided at the top with an overflow to the second, low-oxygen (oxygen-depleted) reactor compart...

A rapid method for fractionating a fat composition, such as butter, containing a mixture of fatty glycerides into two or more fractions. The method comprises heating the initial fat composition, such as butter to liquify all of the fatty glycerides contained therein and then very rapidly cooling the liquified fat compositions, to quickly obtain filterable crystals of the fatty glycerides. By selec...

Two stop or impact members which are situated opposite one another with respect to grippers of a conveyor device are used for detaching or removing the printed products out of their product formation. In their effective position these stop members project into the conveying path of the printed products. The printed products released by the grippers impact against the stop members and under the act...

A radio system broadcasts binary data packets that can be received in mobile receivers. The initial parts of the packets are transmitted periodically. The prefix of each packet includes synchronizing information. The synchronization processing includes seeking a phase and a tracking phase. The transition from the seeking to the tracking phases occurs when the synchronization pattern has been recei...

In the process for in-situ decontamination of ground water contaminated by heavy metal ions, a ground water dome (26) is built up in a well shaft (10) by introducing gas, thus forcing the flow of ground water. This is taken through a siphon with an ion exchanger (50), to which the heavy metal ions are transferred from the water flow by application of a voltage.
