A supply unit for supplying a workplace with electricity and/or gaseous media, with a first, vertically extending supply duct and a second, vertically extending supply duct, wherein the electricity and the media are led to connections on at least one of the supply ducts. From these connections the workplace is supplied and improved such that the ergonomically most favorable arrangement of the supply tubes and electric lines leading to the connections will be possible. This object is accomplished by a section of the side surfaces having an angle of inclination less than 90.degree. in relation to the base such that the ends of the side surfaces pointing away from the base can be connected at a common junction. The connections are arranged exclusively on the outer side surfaces and that the distance between the supply ducts is such that the workplace can be brought into the space between the supply ducts.

A filter for an electrochemical measuring cell with a filter housing and a filter material contained therein is improved, with a simple design, such that interfering gas components cannot reach the measuring cell from the gas mixture. This is accomplished by the filter housing being formed of a porous, gas-permeable material.

A device for measuring the flow of a fluid in a fluid channel, with at least one thermocouple, whose thermojunctions are arranged one behind the other in the direction of flow of the fluid and are maintained at a working temperature higher than the fluid temperature by means of an ac power source 9. The thermocouple is connected to a measuring circuit evaluating the thermocouple voltage U.sub.T. Continuous measurement with high accuracy is possible with a measuring circuit having a switching network, by which the ac power source is connected to the thermocouple at least during the measurement phase, and by which the ac voltage components superimposed to the thermocouple voltage are eliminated by subtraction.

A breathing mask with a mask body designed as a full mask with a field of vision and with a filter with a filter connection 13, wherein the filter can be arranged in the middle 3 of the mask body or to the side of it in the cheek area, is to be improved such that the use properties with the filter attached are improved in terms of the position of the center of gravity, a larger field of vision is present, and there is good adaptability to optical devices. To accomplish this task, the filter is designed as a cassette filter extending in the shape of a U from the middle of the mask body to the cheek area, and the field of vision includes a transparent, elastic elastomer section, into which individual, segment-like eye-protective lenses made of a solid material are inserted.
摘要:
The invention is directed to an electrochemical measuring cell for detecting gaseous constituents in air. The measuring cell includes a measuring electrode and a counter electrode accommodated in a housing. The housing includes an electrolyte chamber and the electrolyte is in liquid contact with the electrodes. The measuring electrode is in diffusion contact with the gas constituents to be detected via a gas-permeable membrane which is impermeable to the electrolyte. The measuring cell is improved so that an effective pressure equalization between the electrolyte chamber and the ambient is made possible in the context of a simple assembly of the housing. For this purpose, the housing jacket surrounding the electrolyte chamber has at least one breakthrough. The electrolyte chamber is separated from the ambient by a gas-permeable stop disposed in the breakthrough. This stop is impermeable to the electrolyte.
摘要:
A method of controlling the operating parameters of an apparatus for maintaining the temperature of prematures and newborns is improved in that the operating parameters are determined based on a precise definition of the thermal condition of the patient and that information as to the bodily well-being based on determined sensor actual values for controlling the operating parameters are applied. For solving this task, the control takes place basically with the aid of at least two temperature sensors which measure the core temperature and the peripheral temperature, respectively, of the patient. The logic combination of the temperature signals takes place in such a manner that, in addition to the absolute temperature of one of the two sensors, the temperature difference between the two temperature sensors is simultaneously applied. In this way, it is possible for the first time that the thermal well-being of the patient is applied for controlling the incubator parameters and not only a single temperature.
