A process for the removal of dissolved metals and/or metalloids from an aqueous medium having a high content of salt wherein the aqueous medium in the presence of manganese (II) ions and an oxidation agent is passed through a particulate carrier material having a specified density, initial average grain size and flow rate, so as to fluidize carrier material particles in the aqueous medium, and whe...

In a hybrid matrix amplifier array (100), a configurable digital transform matrix (116) is initialize with a matrix of transform coefficients. A plurality of digital input signals (M1-M4) are received at inputs of the configurable digital transform matrix (116). The plurality of digital input signals are transformed to produce a plurality of transform digital signals (A1-A4) using the matrix of tr...

A fuel guidance system is provided for an internal combustion engine having in-line cylinders, inlet bores for connector pumps, high-pressure lines between the connector pumps and associated injection valves, as well as a fuel supply line that carries the fuel and communicates with the connector pumps. In the case of connector pumps having a solenoid-valve control, whose control valve controls the...

The double-row ball bearing (1), for a spinning rotor, has race paths (2,2') directly at the bearing bush (3). With the race paths (4,4') on the shaft (5), the bearing row (6) on the side of the spinning rotor (7) has at least one more ball (8) than the opposite row (9).

A method for the preparation of spherical particles from a sludge (2) consisting of small solid particles dispersed in a liquid comprises dispensing the sludge down a tube and out through a nozzle (3) into a container (4) filled with a different liquid (5), so that the sludge is added to the liquid as drops (6). Sludge viscosity is relatively low and the sludge liquid phase and different liquid ar...

The receiving unit (15,54,56) is arranged at the entry to a space for reading off the user apparatus connecting status. It incorporates the technique of a central processing unit for interrogating a detector, receiving from a detector and status indication of the enquired and received signals from the detector, which is connected to an electrical take-off (20,52,53) for the electrical user apparat...

The four main parts of the fixture set comprise two angled guide and holder fixtures (5) for attachment to the wider ladder (1) side rails (2) and two grip claw fixtures for attachment to the narrower ladder (7) side rails (8). All the fixtures have like-shaped fastening parts which fall in a plane separate from the fixture other parts. Each fixture part has a number of position determining pins f...
