Abstract: The dental separator with an inlet, an outlet and a centrifuge has a vibration-damping support. The support is formed with line connections and each inlet and outlet of the separator is inserted into the support and communicates with a line connection of the support. The support of the invention has two parts. The first part can be mounted in stationary fashion and can be disposed removable on the second part of the separator. The two parts are joined together with vibration-damping intermediate components.

Abstract: A separator for a suction air-solid-liquid mixture in a dental suction apparatus has an intermediate container situated beneath an air separation chamber, which has an outlet for the separated mixture. Associated with and situated along side the mixture outlet, a separation device for the solids has a removable sedimentation basin and a clean liquid outlet through which the clean liquid is conveyed into the intermediate container. A tube connecting with the second segment of the suction line passes through the intermediate container from the air separation chamber and has a clean liquid admission port so that the solids-free liquid is fed back into the suction air.

Abstract: A separator including a full-casing centrifuge and detachably mounted settler tank for solids which run off under action of gravity after centrifuge phase. An inlet for mixture to be separated is located in top of settler tank. A pump with suction tube which extends into settler tank is connected by a line to centrifuge inlet port and conveys all liquid arising, from which at least great particles have already settled out into centrifuge.

Abstract: A separator for separating a solid and liquid is disclosed which includes a sensor system for detecting the level of solid that is separated from the liquid and accumulated in a settling tank. A movable locking element locks the separator to the settling tank, and is movable between an open and a closed position. The sensor system is attached to the movable locking element thereby providing protection for the sensing elements which include at least one light barrier.

Abstract: To prevent, as far as possible, malfunction of a dental evacuation system, portions of a free-flowing additive are added at intervals to at least one constituent of the liquid-solids mixture. This is repeated several times during each period of operation of the evacuation system within the first evacuation section, which includes the separator (1). The additive added in portions may be, for example, a disinfectant, a cleaning agent and/or an anti-foam agent.

Abstract: For the separation of a mixture of solids and liquids, which is produced in dental suction units, a separator is used which comprises a housing in which a mixture inlet, a liquid collecting chamber and a lower sedimentation chamber are provided. A drain opening for clarified liquid is associated with the liquid collecting chamber. The drain opening is arranged above a maximum settling level of the solids, and a first section of a drain line extends vertically upwards from the drain opening. To eliminate disturbance of the settling of solids in the sedimentation chamber to the greatest possible extent, the collected clarified liquid is discharged in each case, when a predetermined flood level of the first section of the drain line is reached. The sedimentation chamber is formed in a removable collector bowl so that the collected solids can be discharged.

Abstract: For the supply, control or taking of a medium contained in an implanted container the valve has a valve body (2) in which the flow channel (3) is formed by two pocket bores running into each other at an angle. The first pocket bore serves as an introduction channel (5) for the injection needle (15) and is outwardly provided with a conical widening (4). Into the second pocket bore (6) a particularly spherical closure member (7) is inserted which projects into the introduction channel (5) in the closed condition and whose part protruding into a chamber (11) connected with the container is acted upon by an elastic element (9). Preferably an O-ring sunk into an annular groove of the second pocket bore (6) serves as valve seat (8) for the closure member (7).

Abstract: A device for selectively opening and closing a tubular body organ comprises a sleeve adapted to encircle the body organ and formed with a pressurizable compartment between inner and outer walls. The sleeve is connected by a duct to a supply vessel which is compressible to express a pressure medium into the sleeve by manipulation externally of the body. The supply vessel, which is implanted below the skin of the patient, is provided with means for retaining it in a compressed state, thereby retaining the blocked state of the body organ and preventing passage of a body material, e.g. feces or urine, therethrough. The latter means can be released to permit expansion of the supply vessel and hence return a fluid from the sleeve into the vessel.
