Title: Apparatus for extracting with a liquid, products which are part of solids
IPC: C13B10/10
Filed: 1980-10-03
Abstract: The apparatus comprises inside a rotating drum, two conveying screws nested inside one another and a partition passing through the drum axis to form two series of succeeding cells inside which the solids and the liquid move in counter-current, two liquid channels being so arranged as to start from each cell to end in another cell, the one channel extending along the drum axis while the other channel lies cross-wise thereto.

Patent ES-8107401-A1 (ES)
Title: Method and Apparatus for Detecting Level of Molten Metal in Steel Manufacturing
IPC: G05D9/12
Filed: 1980-10-08
Abstract: In continuous casting, the level of molten steel 2 in mould 4 is detected by taking images of the free surface 5 with video camera 6, scanning lines substantially in parallel with the free surface. The video camera produces signals corresponding to images of the free surface and to those of background. The signals are converted into binary signals wherein the molten steel is represented by one level and the background by the other. The binary signals representing the molten steel are summed to obtain a total area of the molten steel. A predetermined area corresponding to the gravitational flow into the mould is subtracted from the total area to obtain the area of the free surface proportional to the level of the free surface.

Title: Apparatus for writing digital information in a disc-shaped optically readable record carrier.
IPC: G11B20/14
Filed: 1981-01-07
Abstract: An apparatus for recording optically detectable information in a record carrier provided with information areas arranged in accordance with a spiral or concentric track pattern, which areas alternate with synchronization areas each containing the address of the associated information area. Recording is effected with a first modulated laser beam, while a second beam is projected after the first beam for reading the recorded information. The track pattern has previously been provided with a periodic track modulation of a frequency at which the power spectrum of the information to be recorded has a substantially zero value. The apparatus comprises a first and a second filter for filtering a signal corresponding to the track modulation out of the signal derived by detecting the first or second laser beam reflected or transmitted by the record carrier. In series with the second filter there is included a delay network from which a synchronization signal is available. Furthermore, there is provided a phase comparator which, during reading of the synchronization areas, determines the phase difference between the signals obtained from the first and the second filter and which controls the delay network in such a way that the output signal of the delay network is in phase with the output signal of the first filter.

Title: Digital data transmission system, especially a colour television transmission system.
IPC: H04N19/90
Filed: 1983-10-07
Abstract: To convert an input-word sequence into a digital line code of half the bit rate of the input-word sequence, particularly for digital color television signal transmission, an encoder is disclosed which has a difference branch in which the difference (Di) between every two successive input words (Xi-1, Xi) is converted into a difference code word (Di) by adaptive PCM quantization, and a sum branch in which the sum (Si) of the same successive input words (Xi-1, Xi) is converted into a difference code word (Si+Pi) in a hybrid DPCM encoder. These two words are combined into a line code word (Ci) by an adder (9). The quantizing characteristic of the adaptive PCM quantizer (1) is selected as a function of the prediction error present within the hybrid DPCM encoder (2). The decoder at the receiver of the novel communication system splits up the received line code word (Ci) into the difference code word (Di) and the sum code word (Si+Pi) and decodes these words into the original words (D'i, S'i) in an adaptive PCM requantizer (13) and a hybrid DPCM decoder (10, 11, Q1), respectively. The two words (X'i-1, X'i) of the original pair are recovered by addition, subtraction, and subsequent division in half. Like in the encoder, the quantizing characteristic of the adaptive PCM requantizer (13) is selected as a function of the prediction error present within the DPCM decoder (11).
