Patent DE-3814682-A1 (DE)
Title: Device for conveying containers in filling and sealing systems
IPC: B65G33/04
Filed: 1988-04-30
Abstract: A device for the linear conveying of containers in filling and sealing systems for filling the said containers with liquids, pastes, powders, granular material and the like or for sealing the said containers. Known devices of this type generally operate with a conveyor belt, in the case of which it is impossible to prevent filling material from falling onto the conveyor belt and collecting, together with dirt, beneath the belt in particular, so that it can only be removed with great difficulty. In the case of the new device, these difficulties are avoided in that a conveying worm is provided for conveying the containers. A guide rail is arranged alongside the said worm. Beneath the conveying worm and the guide rail there is arranged a slideway. These components are easily accessible from all sides and filling material can be easily cleaned off them. The drive of the conveying worm is controlled in dependence on the filling and sealing process.

Title: Method and arrangement for analog/digital conversion
Inventor: HILLENBRAND RAINER DIPL ING
IPC: H02P7/28
Filed: 1988-05-18
Abstract: In the analog/digital conversion of electrical analog signals in a relatively large signal range, the relative inaccuracy resulting from digitising in the lower signal range is often disadvantageous. For this reason it is proposed to amplify (V) the analog input signal (A) in the lower signal range. The analog/digital conversion follows thereafter and the digital signal (D) is subsequently digitally divided by means of a divisor (X) corresponding to the amplification (V). By this means an increase in the resolution of the analog/digital conversion is achieved, especially at small analog input signals. The method proposed has applications, for example, in the digital control of rotational speed of motors having an analog desired value input. <IMAGE>

Patent DE-3824888-A1 (DE)
Title: Comminution apparatus
Inventor: FRANZEN GEROLD
IPC: B02C18/18
Filed: 1988-07-22
Abstract: In conventional comminution apparatuses, a source of danger resided in the fact that comminuted material or also nails and other foreign bodies were slung out of the inlet for receiving the material to be comminuted and thus could injure the operator. The novel apparatus is to enable a method of operation of the said apparatus which is safe for the operator, the performance of the comminution apparatus remaining the same. The movement of the comminution tools in the direction of the outlet makes possible such a safe method of operation in contrast to the known comminution apparatuses in which the comminution tools work in the direction towards the inlet and thus bring about the dangers described.

Patent DE-3843929-A1 (DE)
Inventor: MAGEDANZ NORBERT DR
IPC: C22B1/20
Filed: 1988-12-24
Abstract: Iron oxide-containing materials and solid fuel are loaded onto a movable grid (1) and the mixture is ignited at the surface and is sintered by sucking through oxygen-containing gases. To reduce the SOx content in the waste gas, a bleed stream of the waste gas (19) having a high content of total SOx produced is taken off separately and is again passed (22) through the load in the final part of the movable grid. An SOx-binding material, for example CaO or Ca(OH)2, as a solution or powder, is added (23) to the load before or in the recycled zone of the bleed stream, which material reacts with the SOx compounds and thus removes them from the waste gas. <IMAGE>
