An apparatus for simulating a human smoking a smokable object which comprises an inhaling device for drawing smoke from the object and a motor which is coupled to the inhaling device for driving the inhaling device. The apparatus further comprises a control circuit for controlling the operation of the motor. The control circuit includes a circuit for receiving an analog signal corresponding to a human draw profile of the smoking of the object, a converter coupled to the receiving circuit for converting the analog signal to a pulse signal and a switching device for applying the pulse signal to the motor for controlling the operation of the motor.

Equipment for smoking smokable objects

An apparatus for determining the effect of dilution and/or diffusion of the gaseous components of a gas flow passing through a gas permeable test object is claimed. The apparatus comprises a source of calibrating gas, a laminar resistance coupled to the source of calibrating gas with the gas flowing through the laminar resistance, and a volumeter is coupled to the laminar resistance for measuring the volume of gas flowing therethrough. The gas from the laminar resistance flows through the test object to a gas concentration measuring device for receiving and for measuring the concentration thereof. A bypass device is provided for bypassing the flow of gas around the test object, and a suction device draws gas from the source to the measuring device.
