Patent DE-4029037-A1 (DE)
Inventor: LEUTHOLD JOHANNES
IPC: B01F15/00
Filed: 1990-09-13
Abstract: In a conching device (1) at least one rotor (2, or 3, respectively) is driven by an electric motor (9). The driving motor (9) is controlled by means of a motor control unit (8). To establish the amount of energy introduced into the conching device (1), at least one motor-operation parameter is detected and evaluated. To shorten the conching time of a conching process to the necessary extent, it is provided to establish the amount of energy introduced into the conching device at least during the viscous-plastic phase of the chocolate mass and to control the conching process in dependency upon the summation value of energy attained. Since the amount of energy introduced during the viscous-plastic phase determines the properties and the quality of the chocolate, a high reproducibility will be ensured.

Title: Continuous fourdrinier cleaner preventing build=up of dirt - has set-back step at the second support bar where the paper web is detached
Inventor: KOTITSCHKE GERHARD
IPC: D21F1/32
Filed: 1991-01-18
Abstract: In the cleaning system for the continuous fourdrinier of a papermaking machine, where the fourdrinier passes over a bar to a take-up bar with a blower slit between them ,the take-up bar is fitted with a set-back step at the point where the fourdrinier (1) leaves its surfaces. The fourdrinier guide surfaces of both bars have about the same width, while the whole width of the first bar is 1.2-3.0 times the whole width of the second bar. The carrier body which supports both bars pivots on an axis parallel to the blowing slit to vary the angle between the fourdrinier and the first bar and/or the support is moved to and away from the fourdrinier. The water spray assembly is formed by two chambers, parallel to each other across the direction of fourdrinier travel, with a distribution chamber and a jet chamber. The distribution chamber, with a water feed connection, is linked to the jet chamber by a number of channels across the fourdrinier width, and the second chamber has at least one water jet opening. The water jet chamber is directly in front of the first bar with a constant delivery of water to the fourdrinier guide surface of the first bar. ADVANTAGE - The system prevents the build-up of dirt at the cleaner, and requires water of a lower pressure with equal distribution over the fourdrinier width. The cleaner functions effectively at different fourdrinier speeds, and can be located where the paper web is separated from the fourdrinie

Title: Solar energy converter for solar power station - uses structured lens system to direct light onto photocell strip flanked by mirrors to capture stray light for reflection onto photocells via additional mirrors
Inventor: LAING NIKOLAUS
IPC: F24S23/70
Filed: 1991-08-12

Patent DE-4202682-A1 (DE)
Inventor: WETTENGEL HEINZ DIPL ING
IPC: H04L25/49
Filed: 1992-01-31
Abstract: In parallel-operating additive scramblers, a predefined pseudo-random sequence of length L is generated in a word generator comprising an N-stage shift register. In order to obtain more than N parallel pseudo-random sequences, the word generator is connected to a network in which further pseudo-random sequences with a different phase angle are produced through modulo-2 additions of existing pseudo-random sequences. The execution of the combination operations limits the maximum transmittable bit string frequency. The pseudo-random sequence is stored in full in a memory (S). The required pseudo-random sequence is generated through shift operations in the ring memory (RS). A ring memory (RS) implemented as a feedback shift register (SR) is used as a memory (S), the outputs of which are connected in each case to an input of an exclusive-OR gate in which in each case one pseudo-random sequence is modulo-2 added to a sub-stream of a serial data stream converted to parallel. The sub-streams are then parallel-to-serial converted in a multiplexer. Data streams with a higher bit string frequency are possible. <IMAGE>
