Abstract: In connecting a flushing port (2) of a toilet stool (1) which is formed so as to face the floor surface to which the toilet stool (1) is installed to a drainpipe (3) of the building, the connection is made by means of a flushing-side connecting pipe (6) which connects to the flushing port (2), a drain-side connecting pipe (7) which connects to the drainpipe (3), and a linking pipe (8) which makes connection between the above-noted two pipes. In making the pipe connections, the linking pipe (8) is cut off in accordance with the distance between the flushing port (2) and the drainpipe (3) or pipe insertion overlap can be used to adjust the length of the linking pipe (8).

Abstract: Method and device for disinfecting a flush toilet. The device is an electrocell mounted in the tank of the toilet, with two wire mesh electrodes immersed in the water in the tank and a battery applying approximately one to two volts of electric potential to the electrodes so that they chemically reduce a portion of the water in the tank to hydrogen peroxide. Then, when the tank is flushed, the peroxide is carried into the bowl where it can kill bacteria.

Abstract: A vacuum sewer system comprises a liquid-driven ejector, the working medium of which is fed to the ejector by a circulation pump from a sewage collecting container, the suction side of the ejector being connected via a check valve to a vacuum sewer network. Air and sewage delivered through the sewer network flow through the ejector into the collecting container. The bore of the discharge pipe of the ejector is substantially cylindrical throughout. Its length is 8 to 20, preferably 10 to 15, times the diameter of its bore and the pipe discharges directly into the open interior of the collecting container.

Abstract: A top mounted valve assembly having a block member with a hinged arm which is fitted through from the top of a supporting surface and actuated by a threaded actuating member. As the actuating member is turned in one direction, the hinged arm engages the underside of the supporting surface. To disengage the faucet, the actuating member is turned in the opposite direction which permits removal. Both single and dual handle faucets can be top mounted by the mounting assembly disclosed herein. An aesthetically appearing faucet results wherein the actuating mechanism is hidden.

Abstract: A vacuum sewer arrangement comprises a valve controlled air inlet duct to let air into the vacuum sewer at a position downstream of the sewer valve. The sewer valve can then be closed immediately after the sewage has passed into the vacuum sewer, because the air required for the sewage transport is received from the air inlet duct. Hence, the amount of air that flows into the sewer through the sewer valve when the sewer valve opens is small, and when the sewer valve is closed, air flows through the air inlet duct into the sewer, which reduces the pressure difference acting on the sewer valve. These measures tend to considerably reduce the noise level. In the case of a vacuum toilet sewer arrangement, the noise level can be further reduced by providing the toilet bowl with a lid forming a substantially airtight and soundproof closure at the top of the bowl.

Abstract: A method and apparatus for collection of fecal matter designed to operate efficiently in a zero gravity environment. The system comprises a waste collection area within a body having a seat opening. Low pressure within the waste collection area directs fecal matter away from the user's buttocks and prevents the escape of undesirable gases. The user actuates a piston covered with an absorbent pad that sweeps through the waste collection area to collect fecal matter, scrub the waste collector area, press the waste against an end of the waste collection area and retracts, leaving the used pad. Multiple pads are provided on the piston to accommodate multiple uses of the system. Also a valve allows air to be drawn through the body, which valve will not be plugged with fecal matter. A sheet feeder feeds fresh sheets of absorbent pad to a face of the piston with each actuation.

Abstract: Toilet bowls made of porcelain are conventionally disposed directly on the floor and/or attached thereto through rigid connections. When the toilet is used, acoustic vibratons are therefore transmitted from the bowl to the floor and spread all over the dwelling. In the case of a multiple unit residential building, the acoustic vibrations even reach the surrounding residential units and disturb their occupants. To overcome this drawback, the acoustically insulating method proposes to insert a strip of rubber foam between the base of the bowl and the floor and to attach the toilet bowl to the floor through a pair of fasteners each including a rubber link, whereby no acoustic short circuit is established between the bowl and floor to thereby considerably reduce the transmission of acoustic vibrations to the floor.

Abstract: A laminated article, for example a bath or shower-tray, is manufactured by providing a preformed shell, for example a thermoformed acrylic sheet, which shell is placed in a mould, together with, if required, a reinforcing board, for example of chipboard or plywood. The mould is then closed and materials are injected into the mould cavity which react to form a reinforcing layer on the shell. Preferably, the injected materials comprise a polyol reactant and an isocyanate reactant which form a layer of rigid polyurethane foam. A reinforcing agent, for example glass fibre, and a blowing agent may also be introduced into the mould cavity.

Abstract: A recirculating shower is especially adapted for showering a person's body with a relatively small supply of water. Before it is directed into the shower stall, the water is first recirculated through an alternate series loop pathway and concurrently cleaned and filtered as well as being heated to a desired temperature level. During the showering of the person's body the water continues to be recirculated, cleaned, filtered, and heated. When the showering is completed, the water is again directed through the alternate pathway for further cleaning and filtering, in preparation for a subsequent re-usage.

Abstract: A device for displacing or washing out blockages in pipe systems. The device has a central tube which can be closed with a gate valve which thereby isolates the pipe above and below the device. Fluid under pressure is introduced through a three way valve that can be positioned to direct the flow of fluid into the isolated chamber above the gate valve if that is where the blockage is or below the gate valve if the blockage is there.

Abstract: A process for detecting the depletion of a cleaning and disinfecting ingredient in a solution such as the water present in a toilet tank and bowl. A solid composition comprising a color indicator in a matrix is located in the solution along with the ingredient. The porosity of the solid composition is maintained within limits to provide a means for controlling the rate of release of the color indicator into the solution. The cleaning and disinfecting ingredient has a bleaching tendency relative to the color indicator so that a display of color is minimal or non-existent for as long as significant amounts of the ingredient are present. The color indicator is provided in sufficient amounts so that, when considering the controlled rate of release, there will be continued release of color indicator after depletion of the ingredient. This will then provide a substantial display of color whereby depletion of the ingredient can be detected.
