Abstract: A lavatory unit (10) comprising a tank body (12) connected to a pressurised water supply (20), and flushing means (14, 21, 23) for releasing water from the tank body via an outlet to a lavatory bowl (11). The flushing means includes an elastic bladder (21) the interior of which is in communication with the tank, the tank being generally sealed otherwise, such that the bladder stressed with the expansion of air forced from the tank as the tank fills with water and the bladder relaxes elastically as the tank empties, and thereby assists in ejecting the water under pressure from the tank to provide a better flushing action.

Abstract: A hose capable of carrying current to an indicator which provides external warning of imminent failure, or leak, due to wear occurring within the hose. The hose consists of an internal (primary) hose which is surrounded by an external (secondary) hose. Positioned in the annulus between the two hoses are two non-contacting electrical wires. At a point, the two electrical wires extend beyond and outside of the hoses. The protruding wires attach to a low voltage power source and to a hose failure indicator, or alarm, in series. When the internal (primary) hose fails, the fluid inside the hose escapes into the annulus between the primary and secondary hoses, making contact with the two electrical leads. This closes the circuit, thereby activating the external indicator, which may be a light or an audible signal or some other type of alarm. The external (secondary) hose is designed to withstand normal operating stress for a reasonable amount of operating hours until the hose can be replaced.

Abstract: A device is provided for connecting two baby strollers together consisting of a pair of bracket units spaced apart and clamped between frames of the baby strollers so that one person can operate the strollers simultaneously for transporting two babies therein.
