Abstract: The invention relates to a process for the electrostatic coating of workpieces which are completely or partly composed of insulating material. In electrostatic coating, the coating material is applied to the workpiece in powder or other freely-flowing form, using the forces of an electrical field, and dried or melted (fused) in subsequent heat treatment. An electrostatically semi- conductively acting surface having a surface resistance of 10<9> to 10<12> ohms is produced in a workpiece to be coated. Such a surface may be provided by coating with quaternary ammonium compounds or by incorporation of quaternary ammonium compounds into the substrate. Thereafter a coating of a powdery or other free-flowing material is applied with the use of coating appliances using the principle of creating an ionized cloud of electrically charged particles of atomized coating material to effect coating of the surface of said workpiece.

Abstract: A clock thermostat apparatus adapted for controlling temperature conditioning apparatus maintains a normal control temperature in a space and during certain selected time periods deviating from the normal temperature control by resetting the normal temperature control to some lower temperature for comfort and energy conservation. The clock thermostat apparatus has a manual temperature selection means and a manual temperature deviation selection means for selecting the normal control temperature and the amount of reset or deviation during the selected time period. A connection means is provided between the temperature selecting means and the temperature deviation selection means to turn the temperature deviation selection means to a lower value when the temperature selection means is moved to some predetermined low temperature. When the normal control temperature selection is reduced by the temperature selection means, the temperature maintained is not reset to a low temperature during a setback time period which might be so low that freezing of water pipes would result in the space wherein the temperature is being controlled.

Abstract: The invention entails a method and apparatus for slaking lime through green lye and is utilized preferably in production of white lye in the sulphate cellulose process. In patent registration number 7804239-7 is shown how through letting the reaction occur during excess pressure, preferably 200-500 kPa, the process can utilize the reaction heat created. The difficulty lies however in feeding the dry lime into a lime slaker with an excess pressure of this amount. The construction becomes much simpler if the lime and the green lye can be mixed before being fed into the lime slaker. This is made difficult by the green lye's temperature, at the lowest 95 degrees C, and the lime's, normally 100 - 150 degrees C. According to the present invention it is now possible to mix green lye with the lime in a mixing container (2) if the mixture is later fed through a suitable pump (7) into the lime slaker (8) so quickly that no reaction worth mentioning has time to occur between the components.<IMAGE>

Abstract: Control circuit for a call counter, especially for call counting circuits where the counting pulses consist of a series of alternating current waves. In order to suppress transient processes which occur at the beginning and end of a counting pulse, the alternating current is switched both on and off when it passes through zero. The passing through zero is detected in a line transformer's primary winding, which is connected to the alternating current source. The zero-passing signals and the counting pulses are sent to a flip-flop circuit which turns on an electronic switch depending on whether both of these signals occur or only one of them. The counting pulse in the subscriber line consequently begins when the supplied alternating voltage passes through zero and the counting pulse in the subscriber loop is terminated when the phase- shifted alternating voltage in the subscriber loop passes through zero. <IMAGE>

Abstract: A PCM switching system requires the assignment of either one or two time slots of a pair of time slots to a port circuit depending upon the type of service (voice only or voice plus data) each port circuit provides. Common resources normally assign a pair of time slots to each port circuit. This wastes time slots when the port circuit is used in a manner (voice only service) that requires only a single time slot. The disclosed arrangement eliminates the wasting of time slots by permitting the on-site reconfiguring of the system resources so that, when desired, only a single time slot can be assigned to a port circuit. This is accomplished by the removal of a first type of carrier control board that controls time slot distribution and by the substitution therefore of a second type of control board that applies the first time slot of a pair to its normally assigned port circuit and applies the second time slot of the same pair to another port circuit on the same carrier that also only requires a single time slot. This permits a given system to be configured initially in a first mode and then be subsequently reconfigured on-site so the port circuits of a carrier can each be assigned either one or two time slots. This arrangement avoids the wasting of time slots or costly on-site modifications as service needs change.

Abstract: A medical instrument comprises a main body having a path formed therethrough, through which a tubular member is insertable or drawable. A valve body is provided in the path of the main body, maintaining at least a liquid-tight state with the rod-like member, when the path is opened by the rod-like member inserted through the path, and closing the path at least in the liquid-tight state, when the rod-like member is not inserted through the path. The valve body has two end faces. The valve body is formed with a first slit openable in one of the end faces and a second slit openable in the other of the end faces. The first slit and the second slit cross each other in the valve body. In consequence, rod-like members being of widely varied outer diameters are inserted through the path of the main body and held therein in a liquid-tight state to thereby reliably prevent blood leakage. Also, blood flow-out when the rod-like member or members are abruptly withdrawn from the path of the main body is reliably prevented. Further, a single valve body is provided so that the construction of the medical instrument can be simplified.

Abstract: The proposed valve (2) has a valve seat (3) of plane design with a valve hole (4) and a rubber-like elastic valve body (5), which has a sealing flange (9) directed against the valve seat (3) and is arranged inside a holder (7). A special feature of the valve (2) is a spigot (6), elastically supported inside the valve body (5), which spigot on the end towards the valve seat (3) has a stop surface (12) of plane design. The stop surface (12) is aligned in such a way that, in closing the valve (2) the sealing flange (9) comes to bear first on the valve seat (3), and the stop surface (12) only once the sealing flange (9) has been applied with sufficient pressure. Due to the elastic bearing of the spigot (6), the whole of the stop surface (12) is applied to the valve seat (3). The valve seat (3) and the spigot (6) prevent the occurrence of any radial deformation from outside, which might lead to damaging of the sealing flange (9) in hydraulic pressurising of the sealing flange (9). <IMAGE>
