Abstract: A rotary grid-structure bucket for separating fine and coarse constituents of sizable materials or products, has a bucket (3) with a separating part (9) located between its back (7) and its front (8) and sides provided with apertures to allow fine constituents (4) of the sizable materials or products (6) to pass therethrough. To make it possible for the separating part (9) to be exploited in its entire length the sides of the separating part diverge symmetrically with respect to the axis of rotation (R) in a forward direction. Ahead of the separating part (9) the bucket has a front part (25) whose sides diverge around the axis of rotation (R) in a forward direction in a lesser degree in relation to the axis of rotation (R) than the sides of the separating part (9) or extend in parallel with the axis of rotation (R) or converge in relation to the axis of rotation (R).

Abstract: A shower and bath tub is adjustable into an upwardly inclined position (A), whereby the tub has a seat (35) on which a person (41) may sit when the tub is in its upwardly inclined position. The seat has two sitting surfaces (36a, 37a) on opposite sides of a forwardly open space (38). In order to prevent faeces from the person sitting on the seat from ending up in the tub, and prevent showering water when showering the abdomen of said person to gather in the tub and/or flow out on the floor, the space (38) may receive a basin (42), which is removable from the space, for collecting faeces from said person (41), and communicates with an output (50) which may be opened to permit discharge of showering water flowing down through the space from the tub (1) when said tub is in its upwardly inclined position (A) and the abdomal parts of a person sitting on the sitting surfaces are showered by means of the shower (64).
