Joining of the prespun thread (4) of a first roll (2) to the prespun thread (3) of the second roll (1) of a ring spinning frame which uses threads of the carded type is achieved by means of a device (13) having a rotating jet of compressed gas, e.g. air. The threads are held by clamps (5, 9) on either side of the device (13). The latter comprises a cylindrical passage through which the thread (3) ...

In a system for detecting motion within a field of view, such as for intruder detection, in which a first condition is sensed to derive a value relating to motion, and an output signal is produced if the value has a predetermined relation to a threshold value, the threshold value is dependent upon a second value derived by sensing a second condition. Thus the signal from a PIR detector 2 may be co...

The preparation of the solid gel electrolyte, which usually follows the pouring of the initially liquid sulphuric acid into the finished storage battery fitted with charged positive and negative electrodes, can be associated with the formation process by finally installing the still unformed plates (blanks), fitting the final current terminals (poles, pole bridges) and forming with a sulphuric aci...
