Patent FI-80548-C (FI)
Inventor: KAREMA TEPPO
IPC: H03M3/02

Granted: 1990-06-11
Abstract: The invention relates to a method of cascading two or more sigma-delta modulators (A, B) by applying an error signal (-Q1), representing the quantization error of a preceding modulator (A) to a subsequent modulator (B) in the cascade to be quantized therein, the quantized error signal (D2) being thereafter differentiated and subtracted from the quantized output signal (D1) of the preceding modulator (A). To improve the performance of the cascade, the method according to the invention is characterized in that the error signal (-Q1) is scaled before said subsequent modulator (B) by a first factor smaller than 1, and that the quantized error signal (D2) is scaled by a second factor substantially equal to the inverse of the first factor, before being subtracted from the quantized output signal (D1) of said preceding modulator (A).

Abstract: A quadrature receiver is disclosed which contains two mixers (M1, M3) in an in-phase receiving path and two mixers (M2, M4) in a quadrature receiving path for converting a received signal to a low IF. Each of the mixers is fed with an oscillator signal (O1 through O4), with the oscillator signal fed to one mixer of the respective receiving path having alternately the same or opposite phase from that of the oscillator signal fed to the other mixer of the same receiving path. In each receiving path, the mixers are followed by a circuit (P', P'') which delivers an in-phase signal and a quadrature signal, respectively. These circuits compensate for the DC offset caused by the mixers.

Abstract: The invention relates to a pipe connection consisting of plastic, metal or suchlike materials. In this case, the insertion end of a pipe acting as a male die is reduced in its external diameter by forming a conical transition region to the unobstructed width of the subsequent pipe, which is used as the female. According to the invention, at least one impact zone is provided on the conical transition region from the pinched insertion end to the actual pipe diameter. This impact zone forms the impact surface for the end surface of the subsequent pipe.

Abstract: In the case of radio networks in tactical operation, special measures for jamming resistance to specific jammers are generally used only when jamming is to be expected or is already taking place, in view of the availability of the existing radio channels and the reduced transmission quality of the information to be transmitted which generally results. However, in the uncoded transmission of speech in analog form carried out in the normal way there is still the risk of a potential enemy infiltrating radiotelephone communication and causing confusion by imitating commands or messages. To prevent this, it is proposed to inject at the transmitting end short sound pulses (TI) into the voice signal (ASS) at pseudo-randomly varying time intervals (F), the sound pulses being evaluated at the receiving end to monitor for the infiltration of a potential enemy in the voice communication. <IMAGE>

Granted: 1996-03-26
Abstract: A washer is described for cleaning the interiors of tanks that hold milk, beer, chemicals and so on.  A main body 2 reciprocates relative to a substantially surrounded and relatively fixed piston 19.  The body 2 oscillatably supports three nozzles 7 each of which is movable through an arc of 60° and which arc is angularly spaced from those corresponding to the other two nozzles 7 by further angles of 60°.  However, the body 2 and nozzles 7 are also indexed, during operation, in steps, around a further axis which is perpendicular to the axis of oscillation and which substantially corresponds to the longitudinal axis of the tank washer itself.  Thus, each nozzle 7 cleans not only on arc of 60° but rotates that arc through 360° so that the whole of the interior of a tank is both washed and substantially rinsed by the three nozzles 7.
