Abstract: In a device for measuring the breath volume of patients, a pair of temperature sensitive sensors are arranged in a tube-like housing of a respiration conduit of a respirator. The sensors are spaced from one another in flow direction and an air resistance member is arranged between them in such way that at least in one of the opposite air flow directions one of the sensors is in a position sheltered from the air flow by the air resistance member. Both of the sensors are connected with electronic circuits respectively and a current supply for holding the temperatures of the sensors on constant high levels. A calorimeter unit is connected to the circuits measuring the current supply necessary to compensate the temperature decrease of the sensors caused by the cool respiration flow. The air throughput is calculated in dependence on the measured current supply.

Abstract: For picking up and disposing of animal dejections in a clean and hygienically acceptable manner, a tool is disclosed which comprises a stick, externally similar to a walking stick consisting of two telescopically slidable members which actuate a mechanical hand similar to the assembly of umbrella ribs so as to open and close such ribs in order to clasp the dirty material and to place it in a baglike disposable container.
