Disclosed is a gear shift controller for an automatic transmission with a gear shift, having a hydraulic torque converter; a gear change group, having a plurality of gears, each gear providing a different transmission ratio for the transmission of power from said hydraulic converter to the output of the transmission, each of said gears having a gear train; a one-way clutch interposed in at least o...

A centrifuge rotor is described which facilitates the preparation of cell dispersions on microscope slides. The rotor is bowl-like in configuration and defines an annular channel having plural circumferentially disposed septa. The septa provide plural separate regions each adapted to receive removable chambers. The outer wall in each region is flat to accommodate a microscope slide. Each chamber h...

A cylindrical drying chamber, consisting of a drying shaft with baffles , is mounted below and in communication with the classifying chamber of a vertical air classifier. The drying shaft is divided by a horizontal partition plate into an upper air distribution chamber, connected to the external fan of the air classifier, and a lower drying chamber, connected to a hot gas supply. The partition pla...

A plant to extract meat from small crustacea, specially antarctic shrimps (Kril) consists of a mechanism to crush the carapaces, one for sepg. any readily floating particles, and one for sepg. the meat. A liq. is used to flush away the floats and the sinks are taken by an ejector to the meat separator. - This system has a higher productivity and a better meat yield than conventional methods.

Hospital mattresses are generally made of foam plastic having predominantly open cell cores and are in the form of a parallel-epipedic block (1) which is provided with a protective layer (12 and 13) consisting of a plastic film which is easy to clean so that injurious substances and bacteria can be removed. Such mattresses have the drawback, however, that when used they produce sounds which are di...

Apparatus for decorticating shrimps of the crangon vulgaris and/or crangon species. It is characterized by a separate arrangement of a supply unit (2) and a decorticating unit (1); the first unit is used to sort out the shrimps, to separate them one by one and bring them to the decorticating unit (1) and comprises an oscillating conveyor provided with a magazine designed to separate the shrimps on...

The baffles used in the production of spherical metal or alloy powders by atomisation of a rotating consumable body, for catching the spherical metal or alloy particles thrown out are coated with a continuous film of liquid, which is preferably formed as a creeping film in such a way as to make possible continuous powder production. Oils with a low vapour pressure, preferably < 10<-6> mbar at 20 t...

A self-extinguishing polystyrenic composition comprising a polystyrenic resin, a fire-retardant amount of a halogenated organic fire-retardant agent and a nitrogen-containing organic compound selected from amines, amides and ammonium compounds containing from 20 to 40 carbon atoms and their mixtures, the nitrogen-containing compound being used in an amount of from 0.5 to 50% based on the weight of...
