A system (10) for determining the level of a fluidised bed uses a minimum number of pressure sensors. A pressure sensor (12) is positioned at the base of the bed, another pressure sensor (14) is positioned at approximately 2.44 m (8 ft) above a distributor plate, and other pressure sensors (16, 18) are positioned at intermediate locations therebetween. The measurements from the sensors are selecti...

Hollow fiber plasmapheresis module and process, said module comprising hollow fibers having cell-retaining pores and an effective length (L) to lumen diameter (D) ratio L/D not greater than 16,400 cm<-><1> D (L and D being in centimeters) within a housing having a blood inlet for conducting blood to the fibers, an outlet for conducting exit (plasma-depleted) blood from the fibers, and a plasma out...

1. Wire rope having a plurality of strand plies, characterized in that at least one quarter and at the most three quarters of the outer strands (4) have a plastic sheathing (5), which protrudes beyond the circle (6) of the wire rope circumscribing the other strands (3).

A process for producing a free flowing powdered solid form of a low softening point hygroscopic substance such as a pure sugar or starch hydrolysate comprises heating a concentrated aqueous solution of the substance to a temperature above its normal boiling point under positive pressure and spraying the solution into a zone, held at a lower temperature and pressure than the solution, through which...

The invention refers to a device on trucks (13) and similar load handling vehicles, that presents a raisable and lowerable lift for loading objects, preferably a forked device, that can be guided across the truck's direction of travel in order to bring about steering of the truck (13) while it is being moved along and out toward a parking space it for the object to be loaded it extends across the ...

The hot rolling of objects with two or more dimensions, such as bars, profiles, etc., takes place between several consecutive pairs of rollers (8-11) each with separate drives (18-21). The spread or width of the material is measured after and/or before at least one pair of rollers, the measurement signals activating controls (24,22,17,23) for the drives of at least one successive or preceding pair...

The d.c. voltage supplied to the electrodes of the separator is set to a first or basic level upon which are superimposed a number in each case two or more voltage pulses forming a pulse group, consecutive pulses being separated from each other chronologically. - The pulse generator is arranged to generate a number of pulses making up a pulse group where the first pulse in a group exhibits an ampt...

The invention refers to a pressure head, which is designed to replace a number of different types of pressure heads, which are used at automobile plate works when straightening automobiles with the aid of a pressure device. The pressure head is equipped on several sides with connections that are connectable to ends of the pressure device, which for example contain a pressure cylinder and possibly ...

The machine is for making cargo pallets, each comprising a wood fibre plate to which are attached (through holes) concrete feet. The machine has a plate feed-in station, a hole-making station, a casting station and a transport mechanism which moves plates from one station to another. - In the hole-making station is a lifting table which has milling tools, and in the casting station is a vibrator t...
