Title: Clock signal generator for video recorder - extracts clock signal from multiple value analogue signal
IPC: H04L7/033
Filed: 1988-07-06
Abstract: The input terminal (10) is connected in parallel to the inputs of three detection units (21, 22, 23), each of which detects one of the three possible signal stages. In the first detection unit (21) the input is compared (25) with a reference The output of the comparator (25) is fed via a delay unit (26) to the input of a monostable multivibrator (27). The mono output is gated (28) by the output of another comparator (24) before being fed to another monostable (29). The second detector unit (22) is a signal null detector. The third detector unit (23) is similar to the first except that the signal is inverted (46) between the delay (26') and first monostable (27') and that the cross-coupled signal from the other comparator (25) is also inverted (47). All three detector outputs are fed via a gate circuit (41) to phase lock loop circuit (44), which produces the clock signal (45).

Title: Apparatus and method for transporting hydrocarbon products
Inventor: GURTNER DANIEL
IPC: B65D88/74
Filed: 1998-08-06
Abstract: The present invention is a tank (20) disposed within a container (10) for storing, transporting and delivering nongaseous hydrocarbon products such as bitumen efficiently, safely and economically. At least one heater (16) is located at the bottom section of the container (10) for raising and/or maintaining the temperature within the container and around the tank (20). An inlet (22) is provided for loading liquidified hydrocarbon products into the tank (20), and an outlet (26) is provided at the bottom of the tank (20) and through the container (10) for unloading the hydrocarbon products. The present invention permits nongaseous hydrocarbon products to be transported in bulk as soon as they are loaded and without waiting for such products to solidify. The preexisting insulation of the container (10) combined with the trapped air in the container and the hull of the tank (20) provides additional insulation for the present invention. As a result, reheating of nongaseous products is obviated as heat loss is minimal. At the same time, temperature on the surface of the loaded container (10) is at ambient temperature, thus making it suitable to existing mode of transporting containers (1). It follows that the present invention is not only safe but achieves energy efficiency and cost savings not possible under prior art apparatus and methods.

Title: Distortion compensation method for speech recognition system - involves speech analysis for data reduction, using division to correct code words
Inventor: ELBERT HARTMUT
IPC: G10L/
Filed: 1988-09-26
Abstract: The method of correcting distortion in speech transmitted from a microphone by lines using the lines for remote control includes carrying out a speech analysis combined with a data reduction of the input signals using the conditions of the analysis for processing. The speech recognition system uses code words at the receiving end which are stored. After forming a detrmined connection between the analysis conditions and the code words, the locally inserted code words are divided, and the results of the division are used for correction, and the corrected analysis parameters are used as a basis for the pattern equalisation. Before or during analysis, a device with logarithmic voltage characteristics such as an A/D converter is used and correction values are obtained by subtracting the analysis parameters of a locally applied code word from those of the speech recognition code word. Correction is made by subtracting the correction values of the analysis parameters along the same path as the speech input path.
