Abstract: Toilet block for a composting toilet which includes a toilet bowl and, situated below this, a holder for receiving night-soil delivered via the toilet bowl and for removing completely or partially broken down night-soil. The toilet block is prefabricated and designed in two parts in the form of an upper part, which is intended to accommodate at least one toilet bowl, and a lower part which is intended to accommodate a holder for receiving and composting night-soil delivered via a toilet bowl in the upper part. The upper part and the lower part are dimensioned such that the two parts can be situated one inside the other in a position for transport and storage. When the toilet block is being installed, the upper part can be lifted and secured relative to the lower part in a raised position in which the ceiling of the lower part becomes the floor of the upper part.

Abstract: Lavatory for connection to a composting container (1) or a sewage pipe forming part of a sewage system. The lavatory has a seat part (11), a lid (12) adapted to the seat part, and a hollow support body (13) supporting the seat part. The support body (13) surrounds or forms an inner duct through which fecal matter passes to the container or the sewage pipe. The rear wall of the duct slopes backwards from the seat part (11) in the downward direction so that it forms an angle (&agr;) with the vertical.

Abstract: Composting device for night soil and other biodegradable material, comprising a receptacle for receiving the material to be composted and on the bottom of which a starting bed is to be spread out. The receptacle comprises an inner, seal-tight lining in the form of a sack (10) made from a flexible, liquid-impermeable material and a carrier (1) intended to support the sack. The sack is constructed with liquid drains (14) for the drainage of liquid which is separated from the composting material. The carrier (1) and the sack-lined receptacle are arranged such that they can be transported as a unit to a depot after the sack (10) has been wholly or partially filled. The bottom of the carrier (1) is constructed with openable hatches (8), which allow the sack (10) with its contents to be deposited in the depot through the said bottom when the carrier (1) is lifted.

Abstract: Arrangement for collecting and composting night-soil and other biodegradable material, comprising a space (23) in which a starting bed (29) has been spread out in order to accelerate the breakdown of material (30) which is dropped down onto the starting bed. The space (23) is lined with an inner layer of a flexible, liquid-impermeable material forming a sack-like container (8) which is open at the top. The starting bed (29) is arranged in the sack-like container, and the arrangement comprises members (40) for pressing the upper edge portion of the container against a ceiling (36) which is located under the floor (32) of at least one overhead toilet and is provided with at least one opening for attachment to a toilet bowl. The sack-like container (8) is designed to enclose the material (30) while the latter is being broken down, and the container comprises members for conveying liquid, which has been separated off from the material, via a screen arrangement (31).

Abstract: Means for use in sealing the joints between the parts of a multi-part housing, for example a two-part turbine housing, pump housing or the like. Said means comprises a rail of a material of the same type as that of the housing parts to be sealed and a strip of a higher-grade material than that of said rail disposed on the rail. Said rail with the strip of said higher-grade material being adapted to be disposed in a groove in the surfaces of the housing parts to be sealed.
