Title: Low temp. carbonising furnace for waste organic matter - has grids of variable inclination and separately regulated heating
Inventor: BALSTER HUGO DIPL PHYS DR
IPC: C10J3/00
Filed: 1979-02-22
Abstract: Organic materials such as straw, fruit skins and vegetable remnants generally, rubbish, wood, coal, etc. are fed into a shaft-like box, through which they slide along grids as they are heated from below in a process for low temperature carbonisation or gasification. During sliding down, the materials are heated slowly to the required temp. and they are drawn out below as ashes whilst the gas produced leaves the plant at the top. Used to make possible the arbitrary adjustment of each pressure-time-temp. characteristic favourable to the carbonising process, by keeping the movement of the material and the transfer of heat by the stream of gas completely separate from each other. As distinct from swirling layer furnaces, the movement of the material is determined only by the grids which by their inclination, length, difference in height determine the thickness of the layer of material and the manner in which it flows.

Patent DE-2914662-A1 (DE)
Inventor: OBRIST ALBERT
IPC: C01F5/02
Filed: 1979-04-11
Abstract: Magnesium oxide is produced from an aqueous magnesium sulphate solution by circulating this solution in a circuit in which magnesium carbonate trihydrate is precipitated by the addition of ammonia gas and carbon dioxide, according to the equation  MgSO4 + 2NH3 + CO2 + 4H2O -> MgCO2.3H2O + (NH4)2SO 4 and the crystals thus formed are calcined to give magnesium oxide. In particular, the process should be seen as a subprocess of a main process for producing magnesium oxide from magnesium silicate-containing starting material, the ammonia gas arising in the main process being used as a precipitant for the subprocess, and the ammonium sulphate arising in the subprocess being added to the starting material for the main process.

Title: Verification circuit in PBX - responds to tone signals from central exchange but excludes spurious tones using narrow band pass filter
Inventor: GLAS JOSE
IPC: H04Q3/62
Filed: 1979-06-29
Abstract: Dial-through tone signals addressed to a particular p.b.x. extension depend on the proper recognition of an instruction signal sent from the public exchange. The exclusion of spurious frequencies is achieved by an arrangement comprising a first operational amplifiers (OV1) followed by a narrow band pass filter (L/C2) tuned to the command tone from the public exchange. Signals not having the correct frequency band are shunted. The remaining output from the second operational amplifier (OV2) is suppressed by a biassing resistor (UR). A monostable (MF) produces an output pulse lasting about 1.5 periods of the applied tone. Each of the monostable responses is counted in an electronic counter (Z). Since the length of the genuine command tone is known, the number of counts required to verify a genuine pulse can readily be selected. The final count put is used for enabling the switching equipment (AE) for evaluating the subsequent dialling tones.

Patent DE-3019823-A1 (DE)
Inventor: BLANTON KEITH A
IPC: G10L13/08
Filed: 1980-05-23
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: Vending machine
Inventor: SCHWARZE H J
IPC: G07F11/18
Filed: 1981-01-20
Abstract: The vending machine possesses, underneath the product shafts, product-extraction boxes which can be pulled out forwards and which are provided with tiltable bottoms. Such a vending machine is to be designed so that there is no need to arrange weighting devices in the product shafts, which devices otherwise rest on the stacked product packs in the shafts. For this purpose, there is mounted under the bottom of each product-extraction box pivotably on an axis (4) extending horizontally transversely to the direction of movement of the box a two-armed lever, of which the arm (5) facing the front side of the box (3) has a nose (51) projecting upwards. This nose is located in a cutout (21) provided in the bottom (2) of the box (3). The rearwardly directed end of the two-armed lever is designed as a detent pawl which, when the empty box is in the position of rest, engages over a transverse web (8) fastened in the rear part of the vending-machine housing and which thus blocks the empty box (3) in the position of rest, so that it cannot be pulled out, with the result that it performs the function of the previously known weighting devices, otherwise located in the product shafts, so that, after the complete emptying of the product shafts, the product-extraction boxes are prevented from being pulled out. <IMAGE>
