Abstract: An apparatus for the disinfection of an air conditioning installation of stationary air conditioning system for a building or a room has an injection device (3, 11, 14) for the accurate ejection of a defined quantity of an antibacterial active substance onto an evaporator (1) of the air conditioning installation. The apparatus comprises, furthermore, a control device (18, 19) for controlling the ejection times of the injection device in the automated repetition mode.

Abstract: An air improver device and method for air improvement in spaces. The device for air improvement for an air-conditioning system comprises a metering mechanism which carries out a controllable metering of the quantity of an active substance discharged per unit time. The device further includes an absorbent receiving carrier, onto which the active substance discharged by the metering mechanism is metered.

Abstract: A security system having a detector to detect specific physical characteristics, such as for example the weight of the pilot, is disclosed. The security system further includes a device to prevent activation of manual flight operation or to switch from manual to automatic flight operation or to deactivate manual flight operation, if the detected physical characteristics do not match predefined physical characteristics. By inputting a personal code into an inputting device the pilot may identify himself as an authorized operator at any time with regard to the security system.

Abstract: The security system has means (3) to detect specific physical characteristics, in particular the weight of the pilot. Moreover, means (11-14) are present to prevent activation of manual flight operation or to switch from manual to automatic flight operation or to deactivate manual flight operation, if the physical characteristics detected by the detection means (3) do not match predefined physical characteristics. In this manner it is possible to prevent aircraft hijackers from taking control of the aircraft and approaching a target of their own selection.

Abstract: A sales-inducement business method which preferably uses a roulette wheel provided by merchants for their customers to play for having charges paid by the customers for goods and services refunded by the merchant if the customers win the game. Described as preferred games are miniature roulette games having horizontal roulette wheels 13 rotatable in horizontal roulette tables 14 and optionally vertical roulette wheels 21 rotatable in vertical roulette tables 22.

Abstract: A plurality of plates are placed in overlapping relationship in an elongated array extending along the spinal column or other body area to be protected. The plates are pivotally interconnected by joints which allow relative rotation to a limited extent between the plates and limited longitudinal movement between the plates so that the armor structure conforms to body changes during normal movements. Overextension is prevented by abutment of the plates against each other, limiting harmful movement of the protected body portions. An arrangement particularly adapted for protecting the spinal column is disclosed.
