A comparator 5 compares the present pressure with the pressure in one of the addresses to give a display 6 of barometric tendency, i.e. whether the pressure is rising or falling. <IMAGE>
Patent GB-2050125-A (GB)
Title: Data converter for a speech synthesizer
IPC: G10L13/08
Filed: 1980-05-01
Abstract: Data converter for a speech synthesizer system wherein encoded formant parameters as stored in a memory are decoded and transformed or converted to reflection coefficients in real time by means of a circuit implementing a Taylor series type approximation. The reflection coefficients are then quantized and input to a speech synthesizer which utilizes quantized reflection coefficients to synthesize speech. The use of the coded formant frequency speech data which inherently contains more speech intelligence than reflection coefficient speech data enables a speech synthesizer system which utilizes quantized reflection coefficients to operate at a significantly lower bit rate than would otherwise be possible where reflection coefficients are employed as the speech data stored in the memory.

Title: Device in connection with mixing apparatuses
IPC: B01F29/63
Filed: 1979-06-18
Abstract: A concrete mixer exhibits a rotatable drum (1) with lying axis of rotation and with one end (11, 13), which is provided for the input of the material that shall be mixed, and one end (12) which is provided for the discharge of the mixed material. A number of mixing wings (22) are positioned in a shell and exhibit a screwlike arrangement, so that during the rotation of the drum (1) in the mixing direction they tend to convey the material in axial direction towards the input end (11, 13) and during the rotation in the discharge direction, they will feed the material in axial direction towards the discharge end (12). Additional mixing wings (23) are so positioned in the shell that the material carried along by one of the wings slides off the same, so that this material then hits the belonging outer wing (23). This wing exhibits such a screw-form that because of its inclination it tends to convey the material in direction towards the discharge end (12) whereby the material gets a double directed axial movement. In one layer the material is directed towards the input end (11, 13) by the action of the first wings (22) and in a second layer the material is directed towards the discharge end (12) as a result of the action of the additional wings (23).
