Abstract: A chemical toilet cabin includes a platform, vertical side walls, a frame with a door and a roof; reversible joint connection provided along the edges of the vertical walls and of the frame and on the opposing faces of the platform and of the roof to removably join the walls, the frame, the platform and the roof, reversible locking mechanism of the joint connections being provided between the walls, the frame and the platform and the roof; in which each of the vertical side walls is made of two panels configured in such a way as to be joined one another along two corresponding sides by a snap connection.

Abstract: A chemical toilet cabin includes a platform (3), vertical side walls (4, 5, 6, 7) connected to the platform, and a roof (8) connected to the walls. Reversible joint connectors (9, 10, 11, 12, 21, 22) are along the edges of the walls and on the opposed faces of the platform and the roof to removably join each wall to the walls adjacent thereto, the platform and the roof. A reversible lock (13, 14, 15) for the joint connectors are provided arranged between each wall and the adjacent walls and between each wall and the platform and the roof.

Abstract: A tank assembly (1) is mountable on a tank truck for the collection of waste material from a portable chemical toilet and for the maintenance thereof includes an outer rigid housing (10) and an inner tank (14) enclosed in the housing (10) and provided with waste material loading nozzles (18, 19) and waste material discharge nozzles (17). The outer housing (10) includes an inner wall (31, 32) having a surface which is complementary and substantially mating and closely contacting the surface of the inner tank (14). The outer housing (10) and the inner tank (14) are made of plastic material. The inner tank (14) has a substantially spherical shape. The tank assembly (1) is light-weight, of low production cost and does not have corrosion problems.

Abstract: A waste material discharging device in a sanitary appliance comprising a seat (1) and a vessel, to which the seat is pivotally connected, having an opening for conveying and collecting the waste material. The device comprises a roller (4) rotatable in only one direction about its axis, integral to the seat (1) and placed therebelow at said opening, scraping means (5) stationarily arranged parallel to the roller (4) and substantially in contact to the surface of said roller, driving means (11), operable by a user, for driving unidirectional and intermittent, axial angular displacements to the roller, and means for dispensing (15, 18) a cleansing and sanitizing liquid, directed toward the surface of the roller (4) and driven by the same roller rotation driving means (11).

Abstract: A connection group for movable road barriers, comprising a pair of jawed joints (3, 4) suitable for being attached to the respective upright members (1, 2) of adjacent barriers and connected to each other in such a way as to compensate imperfections as regards the coplanarity and/or the parallelism of said upright members due to the conformation of the ground on which the barriers are set up.
