Title: Evaporative power-generating plant - uses compressive condensation, with liq. heated to superheated vapour and expanded adiabatically into saturated range
Inventor: GENSWEIN ALFONS ING GRAD
IPC: F01K19/02
Filed: 1980-09-10
Abstract: The evaporative power-generating plant embodies a superheater and employs compressive condensation. The working fluid's residual heat is thus kept within the system and all external heat input converted to work. The liquid working fluid - high or low boiling point - is heated to convert it into super-heated steam/vapour which is fed, at high pressure, to an expansion engine. It expands adiabatically to near-saturation, the saturated exhausted vapour being led to a compressor. This compresses it, at constant pressure, to produce complete condensation after which it passes through a feed pump to close the cycle.

Title: Linked belting junction prodn. - using filler insertion in free space in coil strands to simplify bonding insertion
Inventor: BERGER HEINZ
IPC: B21F43/00
Filed: 1980-10-04
Abstract: In the manufacture of a linked belting, such as for papermaking machines, the two sets of strand coils are aligned for the insertion of the bonding. The free space for the intermediate strand coils, at least in the junction zone, is so filled that the final strand coil cannot distort in the direction of the linked belting. Pref. butts are inserted to fill the free spaces in the intermediate strand coils, in the form of needle studs which move up and down with the advance cycle of the linked belting, or they can be flexible blades, or brush bristles or rubber pads. Alternatively, strand coils can be shaped so that there is a coil with its longitudinal axis across the line of the linked belting, to fill the free space, formed by passing it over a roller on a moving carrier, and is passed into the intermediate strand coil at an angle between the two coil strands, and a number of such filler coils can be inserted at the same time, in a movement of an inserter across the belting width. The system simplifies joining linked beltings together, so that prodn. costs are reduced to allow the advantages of linked beltings to be employed without increasing equipment costs.

Filed: 1980-12-02
Abstract: The cassette consists of a tape-type sound carrier, wound on spools and placed in contact with a sound head. The tape is ready for dictation and the digital indicator is set to zero. As the tape runs, the length of dictation is calculated from the dictation time and displayed on the digital indicator as typewriter lines. The cassette (1) is then placed in the playback apparatus, and the tape drive started. Before replay however, the indicator on the playback unit is set to zero so that as rewinding takes place, the indicator displays line numbers, until the figure displayed on recording is reached i.e. maximum figure. Thus, the number of lines remaining, and required to be distributed evenly on the document being typed, is known at any time.

Title: Digital filter
Inventor: GEPPERT RUDOLF DIPL ING
IPC: H03H17/06
Filed: 1981-03-26
Abstract: In a digital filter of the FIR type in which a number of consecutive stored input values are in each case multiplied by a coefficient corresponding to the filter characteristic and the products are added together, the coefficients being symmetrical to the mean sampling value, the sampling values are stored in parallel in two memories to increase the processing speed and are simultaneously read out and added together, and only the sum is fed to the multiplier. Two multiplications are thus replaced in each case by a single multiplication and a preceding addition, the read-out of the sampling values for the addition being carried out by the two parallel memories so quickly that the maximum speed of the fastest available multiplying arrangement can be fully exploited. To control the two memories for reading in and out, an arrangement with four counters is indicated which enables simple organisation of the addressing and thus simple control of the counters. <IMAGE>

Title: Method and device for separating a mixture of materials into components having differing degrees of grindability
Inventor: NIED ROLAND DR
IPC: B02C19/06
Filed: 1981-10-10
Abstract: A method for separating a mixture of materials made up of components having differing defrees of grindability into an easily grindable component and a component which is more difficult to grind is described. The mixture of material is placed in a fluidised state by applying vapour or gas jets and subjected at the same time to impact comminution whose intensity is set by selecting the operating pressure and speed of the jets in such a way that only the more easily grindable component of the mixture of materials is comminuted. After the impact comminution, the mixture of materials is subjected to centrifugal force separation by means of which the more easily grindable component of the mixture of materials is separated off as fine-grade materials and the component which is more difficult to grind is separated off as coarse-grade material from the unground mixture of materials. A flow bed jet mill with centrifugal air separator arranged above the flow bed serves as a device for carrying out the method, the mill housing in said flow bed jet mill having in the circumferential area of the centrifugal force air separator an annular gap which opens into a discharge chamber for the coarse-grade material.
