Abstract: An incubator for transporting babies while keeping them, during the transportation, under a constant ambient temperature is thermally insulated on all sides and comprises in the interior receptacles containing a chemical compound preferably tetradecyl alcohol having a melting temperature between 30*-40*C and emitting latent heat when cooling down and crystallizing, this emitted heat being sufficient to compensate heat losses during transportation of the incubator and so to maintain the inner temperature for a certain time without heat supply. Before the transportation the chemical substance is melted by means of an electric heating device supplied from the outside and a thermostat keeps the inner temperature, before the transportation, slightly above the melting point of the substance.

Abstract: A heat insulated flexible connection for a cryoprobe comprises an inner tube for the passage of a cooling medium which is advantageously flexible and arranged within an outer tube portion defining a return flow space for the cooling medium and held in position by axially arranged spacers. The outer tubular portion is surrounded by a plurality of axially arranged insulation rings which have ends which may be loosely interengaged to permit flexible movement of the tube and which are shaped so as to space an outer cover from the outer tube which surrounds the inner cooling tube. The flexible tube is connectable to a probe which includes a tubular probe housing having an end which is closed and defines a probe contact surface. The inner tube of the flexible tube extends into the housing and terminates short of the surface in a space which defines an evaporation chamber adjacent the probe contact surface. A surrounding intermediate tube arranged within the housing around the inner tube defines a return flow space and also an insulation space between it and the outer housing. Heater means are contained in the housing which advantageously are located in the housing wall or in the tube surrounding the inner coolant supply tube.

Abstract: A device for measuring or detecting gas comprises a mounting base having a sample connection for connecting an opened vessel thereto which is adapted to contain a sample to be tested. A container carries a collapsible bellows therein and the bellows has one wall which is common to a container wall. A reversing valve is connected to the container and also to a pump to selectively connect the pump to the container or connect the container to atmosphere. The container includes a check valve for permitting discharge of gas therefrom and a switch is actuated by movement of the bellows to switch the reversing valve in accordance with whether it is desired to have the pump or the atmosphere connected into the container. An under pressure measuring device is connected into the container and is also connected to the reversing valve to switch the valve in accordance with the pressure sensed in the bellows or the container. This control works in conjunction with the control which operates upon expansion and contraction of the bellows to operate the reversing valve.

Abstract: A temperature responsive device for controlling the flow of fluid particularly for medical devices, such as a breathing apparatus and a vaporizer for anaesthetics, comprises a housing which has a supply inlet for the gas and includes a chamber at its lower end which is adapted to contain a liquid such as an anaesthetic. The interior of the housing defines a first pressure compensating passage for the gas in which a part of the inflow of the gas flows through a spiral around a top portion of the housing and then down to a lower spiral defined around the fluid chamber for the liquid, such as the anaesthetic. A second partial gas flow passage extends in the form of a by-pass from the inlet through a valve passage to the outlet. Flow from the fluid chamber to the discharge are regulated by means of two concentric rearranged movable valve members, the first valve member containing the expansible means which is located in the anaesthetic material includes a surface which is spaced from a valve surface of the second movable member and which defines the flow passage from the fluid chamber to the outlet. The second movable member defines a flow passage with a fixed portion of the housing and it is biased in a downward direction against the housing but is movable against this biasing pressure to vary the passage in the by-pass line. In addition, this same second movable member defines a surface which, together with the first movable member, defines the control passage from the fluid chamber to the outlet.

Abstract: In a method for mixing two gases in a predetermined ratio, the two gases are supplied to respective chambers, having fixed or adjustable preselected volumes, through respective first pressure regulators while maintaining the discharge pressures of the two first pressure regulators in such predetermined ratio. The flow of the two gases to the chambers is then interrupted, and the two gases are thereafter discharged from the respective chambers to a common discharge line through respective second pressure regulators while maintaining the discharge pressures of the two second pressure regulators in such predetermined ratio. The apparatus includes adjustable means for conjointly adjusting both the first and second pressure regulators so that the discharge ratios thereof are equal and equal to the predetermined ratio. A reversing shut-off valve may be used to connect the chambers to the first pressure regulators or to discharge the chambers through the second pressure regulators. A magnetically biased torsion resistant lever may be used to commonly bias the pressures of the first and second pressure regulators and also to adjust the respective pressure ratios. The respective first and second pressure regulators for each gas may be combined into a single unit.

Abstract: An alarm device particularly for respirators having a pressure gas supply includes a housing, or body, having a first gas chamber which is adapted to be connected to the pressure gas supply. A valve is movable in the first gas chamber and it closes off a connection of the chamber with a second chamber having a second valve therein which closes the second chamber in respect to a discharge gas passage which connects to a signaling device such as gas operated whistle. A spring biases the first valve toward an open position and when the gas pressure in the line reduces, it opens the first valve and permits flow of the gas under pressure into the second chamber until it pressurizes sufficiently to open the second valve to permit the gas to flow to the signaling device and actuate the whistle. The second valve includes a control device defining a throttle passage which permits flow from a connecting chamber portion of the second chamber on one side of the second valve into an equalizing chamber portion on the other side of the second valve. After some time, the pressure equilibrium is again established in the second gas chamber to close the second valve again and to stop the flow of gas to the signaling device.
