A decanter centrifuge having a screw conveyor within an imperforate bowl is provided with an annular baffle carried by the screw conveyor. Light phase material and heavy phase material is separated from a mixture thereof fed to the centrifuge bowl. The heavy phase discharge port, usually in a tapered portion of the bowl, is preferably at a greater radial distance from the rotational axis than the ...

A rotary die cutter for die-cutting blanks one after another has a blank feed unit, a pair of cylinders for die-cutting the blanks, and an endless member running synchronized with the cylinders. The blanks are gripped by grippers mounted at equal spacings on the endless member. The cylinders are adapted to allow the grippers to pass between the cylinders while gripping the blanks.

The invention relates to a cutting machine, in particular a circular-knife slicing machine for foodstuffs, having a housing to which a cutting tool assembly having a cutting tool acting on the product to be cut is fixed by means of a closure so as to be detachable in operation. The object on which the invention is based is to provide a cutting machine of the type described at the beginning, in whi...

A pneumatic vehicle tire which has fine slits in the tread. These slits are inclined relative to the circumferential direction of the tire. In order to increase the frictional connection to the roadway, to make the wear of the tread more uniform, and in addition to be able to use mechanically stiff plates for the associated vulcanization molds, the fine slits are twisted about an at least approxim...

The invention relates to a method of producing contours, for example raster figures, on metallic or non-metallic material samples such as metal sheets, foils, plastic materials etc., in order to determine the degree of deformation or the material flow in materials to be cold-formed in forming and material testing technology. The object is to develop a simple method of producing contours on materia...

By means of the device, portions of a paper or film web 14 are inserted between the food slices. The cutting apparatus with the knife 11 is controlled by a step motor which is started by the cutting machine cutting the slices. The triggering pulse of a further step motor, which drives the paper feed 4, is derived from the position of the cutting apparatus. A uniformly driven conveyor belt 6 extend...

The subject of the inventon is a safety lock for granulators whose housing is divided in a plane running through the axle of their granulator rotor into an upper part and a lower part, the upper part being connected to the lower part so as to swivel about an axis parallel to the axle of the granulator rotor and the granulator rotor being mounted in the upper part. This safety lock consists in the ...

The multilayered composite wound dressing comprises of a semipermeable membrane, a permeable supporting and reinforcing layer, and a non-stick, self-sealing biodegradable tissue interface. The semipermeable membrane may be a synthetic collagen, an alginate or a biocompatible polymer and it controls the rate of water vapour transmission from the wound surface. The permeable supporting and reinforci...

PURPOSE:To check data as soon as a multiple is generated by applying 1/n multiplication to the data obtained by applying (n) multiplication to the input data given from outside and comparing the 1/n-multiplied data with the input data given from the outside. CONSTITUTION:The output of an n-multiple generating circuit 4, i.e., an (n) multiple of an external input data 1 is supplied to a 1/n-multipl...

A safety binding for a ski including a body having a jaw for holding a ski boot and a support fixed to the ski. The support has a rear transverse face with two recesses therein, and a front transverse face. The body includes a transverse face having two projections thereon, each adapted to engage one of the recesses of the support. The recesses and projections define two lines of support convergin...

The watch case comprises in particular a calibre (1) made of hard sintered material and a back (7) attached removably to the lower part of this calibre. It includes a ring (8) for fixing the back (7), the ring being rigidly attached to the perimeter of the lower aperture of the calibre by means of a plurality of tapped pins (10) solid with the ring (8) and fixed permanently into receiving holes (1...

The binding comprises two lateral jaws (4, 4') mounted so as to be displaceable through the action of an elastic member parallel to the plane of the ski between a closed position in which these jaws interact with the sole of the boot and an open position. These jaws, carried by arms mounted so as to pivot on the ski to the rear of the said jaws have, when seen in plan view, a generally conical sha...

The present invention relates to a process for the preparation of polyurethane foams capable of being flame laminated and high frequency welded, comprising reacting: (a) polyisocyanate, (b) a compound having a molecular weight of from 400 to 10,000 containing at least two isocyanate-reactive hydrogen atoms and (c) a dialkoxy-phosphonyl-N-alkyl-formic acid amide of the formula: wherein m...
