A method of manufacturing a pole member and an armature for a latching-type solenoid actuator having a selected latching force, said method comprising the steps of: forming said pole member out of steel; forming said armature out of steel; selecting a latching force for said solenoid actuator; determining what the hardness of said pole member and said actuator should be based on the selected latch...

In a hammer mill the beater plates (18) are of reduced length and fixed to and in alignment with holders (19) pivotally attached to a disc (11). The reduced-length plates are reversible in position to provide a second working end when one end is worn and the plates (18) are readily replaceable on the holders (19) thus reducing material wastage and machine down time. The holders (19) may be of less...

The height of the stack at the loading or unloading station is governed by a hoisted stack platform driven by an electric motor which also positions a sensing arrangement in turn controlling the rate of travel of the platform. A platform carrier (1), supporting the stack of sheets (2), is lifted and lowered by means of chains (3) wound on a drum (4) rotated in either direction by a motor (6) and g...

The present invention comprises a novel culture method and device in which living cells or subcellular biocatalysts are immobilized by the opposition of a centrifugal force field and a liquid flow field. The immobilized cells or biocatalysts are ordered into a three-dimensional array of particles, the density of which is determined by the particle size, shape, intrinsic density and by the selectio...

A centrifuge apparatus is used for collecting white blood cells (WBC), primarily mononuclear cells, from whole blood stratified into layers. A thin mononuclear (MNC) layer is formed at the interface of red blood cells and plasma. A barrier is positioned in the separation vessel of the centrifuge at a location to intercept the thin layer. MNC fluid is allowed to pool behind the barrier before colle...

Eine die Analyten (1) enthaltende Analyselösung (3) wird durch eine Membrane (7) einer Dialysezelle (11) von einer Akzeptorlösung (5) getrennt. Die Membran (7) ist so gewählt, dass die Analyten (1) von der Analyselösung (3) durch die Membra...

A non-step transmission is provided with a rotor (17) of which input shaft is connected to a drive source (1), another rotor (19) of which output shaft (19a) is connected to a driving load, a plurality of exciting windings for controlling the inter-coupling-force of said rotors (17, 19), and a control unit (4) for recognizing the condition of operation of a vehicle (2), and determining a gear rati...

The invention concerns a method in the threading of a paper web or of an equivalent web-like material in a winding device, in particular in a slitter-winder, in which winding device the paper web (W) or the equivalent web-like material is wound from a web reel (2) or equivalent onto another roll. In the method a threading wedge is formed into the paper web (W) or equivalent web-like material, whic...
