Title: Digital DPCM coder/decoder for high processing speeds, particularly for television picture signals
Inventor: PIRSCH PETER DR ING
IPC: G06T9/00
Filed: 1984-05-09
Abstract: In a DPCM coder with two-dimensional prediction, the summands of the prediction value are suitably calculated separately from one another in parallel predictors. In known coders, the summands are then added together and the sum is subtracted from the input value as prediction value. This has the disadvantage that a further adder which limits the maximum processing speed of the overall coder is located in the time-critical loop. Having special regard to television picture signals, in the coding of which high speed is of importance, the two separately calculated summands of the prediction value are subtracted successively in subtractors (1, 2) following one another in the coder according to the invention, as a result of which the time-critical loop exhibits one adder less than the prior art. To decouple the different paths, thus created, of the recursive loop from one another in time, a delay section (6) is located between the two subtractors (1, 2), the delay time of which is equal to one sampling period and the delay of which is taken into consideration in the remaining part of the coder. A part of the coder can also be used as decoder by means of a mode selection switch (S), a further input (ED) and a further output (AD), that is to say the type of construction is uniform for the DPCM coder and the DPCM decoder. <IMAGE>

Title: Process for suspension separation, in particular sludge dewatering
Inventor: KOLLMAR ULRICH
IPC: C02F11/121
Filed: 1984-11-14
Abstract: A process for suspension separation, for example for sludge dewatering, provides that before the pressing station, a continuous introduction of fibre materials in solid or suspended form is carried out. As a result, it is possible, for a predetermined final dry matter content of the suspension, matched to the particular composition of the sludge material supplied, to add a precisely metered amount of a fibre material, so that after the dewatering process, for example by pressing, precisely the predetermined dry matter content is achieved which is required, for example, for storage in landfill. In order to ensure thorough mixing, the fibre materials are preferably added as a suspension directly into the transport pipe of the sludge material, where, depending on the dimensioning and design of the supply apparatuses, a separate mixing means can further be connected downstream.

Inventor: SEIBOLD PETER DIPL ING
IPC: G08B13/00
Filed: 1985-03-16
Abstract: Upon unauthorized removal of a car radio (2) from the chassis (C) of a car, a memory (5) which has a code stored therein is changed and inhibits operation of the car radio. The memory is retained in a predetermined memory state either by continuously receiving data inputs, for example from a potentiometer slider of a potentiometer (6), or data entered into an RAM energized only upon being properly connected in the vehicle. Alternatively, a user may enter a code, for example by operation of station selector buttons (4) of the car radio (2), and upon operating a set code switch (9), which code is destroyed upon removal of the radio, or upon failure to enter the correct code from time to time. The selected code can be encrypted by a preset encrypting memory chip, for example within the memory (5), and the encrypted code displayed, with only the manufacturer knowing the encrypting data, and releasing the encrypting data only to an authorized person, thereby permitting continued use of the radio by the authorized person even though the code word may have been forgotten.

Title: Power saw for machining wood, with a guide rail and a saw chain revolving on it
Inventor: DREHER ERNST

Filed: 1985-10-31
Abstract: In the power saw for machining wood, with a guide rail and a saw chain revolving on it, a direct lubricating-oil feed to the sliding surfaces of the guide rail 2 or saw chain 3 and their guide members 12 is used in order to prevent blockages or interruptions in the lubrication. Here, the oil-feed sleeve 4, through the bore 13 of which the oil is directed from the pressure passage 20, is made virtually sharp-edged at its end face 5 by means of a chamfer 6 and projects through one of two elongated holes 14, put through on one side diagonally and parallel to one another at the guide rail 2, up to the guide-groove side face 11 of the guide groove 7. The oil-feed sleeve 4, which is pressed against the bore wall 16 of the pressure passage 20 in such a way as to be locked against displacement, has in each case in one of the two elongated holes 14 just as large a minimum clearance space in the longitudinal direction as the largest possible displacement of the guide rail 2 required for the chain tensioning. An optimum supply of lubricating oil by means of the oil-feed sleeve 4 of the guide rail 2 fastened to the power-saw body 1 or side plate 8 is also ensured if, for example, a small hollow space develops at the rail bearing side 15 due to dirt particles when fastening the cutting outfit. <IMAGE>
