The invention relates to transdermal drug patches for the controlled release of drugs to the human skin, comprising (a) an impermeable backing or covering layer, (b) a reservoir layer adjacent to, and in close contact with said backing or covering layer, said reservoir layer comprising a polymer matrix composed of a rubber and an adhesive resin material wherein said therapeutically active agent or...

A measured position signal is fed to at least two channels which respectively contain a transformation component and an estimation filter. One channel (S1) covers transformation and estimation of the first derivative of the movement or the position parameter, and the second channel attends to the transformation and estimation of the other derivative of the movement or speed parameter. The output s...

The filter makes use of the information attributable to the time between the actual onset of object position variation and the moment when it was observed, and the data are used in a process of inward pivoting. A memory is incorporated in the equipment, in which the estimating information may be stored. When the filter is set at zero, the memory is connected and feeds the data to it. Simultaneousl...

A number of estimating filters are arranged with different characteristics in order to form a number of combinations. A primary filter or combination is activated when the complex incoming signal contains a number of parameters, and a secondary filter or combination is activated when a further number of parameters are present in the incoming signal, and so on. The filters carry out optimal signal ...

An ammunition unit (5) is located in a firing position (L''). A predictor (2) receives continuous information concerning the target. A ballistic calculator (3) receives data covering firing conditions, e.g. the ammunition unit starting and flight speed, wind strength, etc. A calculation circuit (1), target predictor and the ballistic calculator are connected together in a closed loop in which is g...

A local manoeuvring ramp is provided which has reading heads for used labels, and numerical and function keyboards for giving orders to the control system. Connection between the keyboards and the control system is either via a radio-wave borne message or by a series-bus. Connection is effected by a multiple-pole unit. - The transmitter in the manoeuvring unit and the receiver in the control syste...

A thread insert (3) is removed from a reactor component (1) with the help of a sparking tool that contains a spark electrode (7) and a control body (10) made of insulting material located at its end face. The control body (10) is inserted in the thread insert, after which two axial grooves are spark-machined in it. A screw tool of about the same shape as the sparking tool is then inserted in the g...
