Abstract: An apparatus and method for inflating a casing enclosing a sausage stick is disclosed, wherein the apparatus includes a holder configured to receive the sausage stick enclosed in the casing and move together with the sausage stick thereby received from an inflation starting position to an inflation end position, and an inflating needle configured to penetrate the casing of the sausage stick received by the holder and to follow the holder immoveably relative to the holder moving together with the sausage stick from the inflation starting position to the inflation end position to inflate the casing between the inflation starting position and the inflation end position.

Abstract: An apparatus is adapted to be secured to a pressure regulator, relief valve, or any other valve and allows the user to control the position of the valve. According to one embodiment, the pressure regulator remains fully open until a desired maximum fill pressure within a boiler is reached. Upon reaching the maximum fill pressure, the valve is automatically and substantially instantly closed. Consequently, the pressure within the boiler never exceeds the maximum allowable pressure of the pressure relief valve, thereby preventing the accidental discharge of hot, high-pressure water from the boiler. Moreover, because the valve remains fully open until the maximum fill pressure is achieved, the amount of time to fill the boiler is substantially reduced. According to another embodiment, a relief valve remains fully closed until a maximum pressure is exceeded, whereby the valve is substantially instantly fully opened.

Abstract: Apparatus for use with automatic pool cleaners includes a tube which defines a flow channel for water drawn pump from the pool through a house by a remote pump. The tube includes tubular sections (10A, 10B) joined by a joint (11) which operates to move one tube section between first and second angularly displaced positions. Means are provided for periodically causing the movable tube section to move about the joint with sufficient force to impart movement to the hose to cause a change in direction of the cleaner.
