Patent EP-0167430-B1 (EP)
IPC: H04N7/083
Filed: 1985-06-04
Granted: 1988-07-06
Abstract: In a broadcasting system with time division multiplexing of digital signals containing a synchronization pattern and analog signals, sync extraction is achieved with a process including detecting the extreme values of the signals to be subjected to decoding, after they have been amplified with a gain G, with a time constant compatible with the low cut off frequencies to be accomodated; the gain G is controlled as a decreasing function of the difference between the extreme values with a time constant greater by several orders of size than the repetition period of the multiplex; before decoding and determination of the extreme values, there is added to the amplified signal a DC component which is a decreasing function of the sum of the extreme values, until the retrieval of the clock signal and identification of the synchronization pattern downstream of the coding.

Abstract: A method and an apparatus for determining the dielectric constant of a material (11) wherein the material is loaded to a short-circuited microstrip (10) and microwaves are fed to the microstrip for providing a reflected signal (V<sub>4</sub>). The reflected signal is compared with a reference signal (V,) both under load and not load conditions of the microstrip for obtaining the modulus and the phase of the reflection coefficient, the dielectric constant being a function thereof. The measure of the phase angle between the reference and the reflected signal in both conditions is obtained by handling the reflected signal with a first phase shifter (6) and a second calibrated phase shifter (7) cooperating with a zero detector (4). The method and the apparatus of the invention is especially designed for a quick and easy measure of the amount of unburnt coal in the ash coming from a combustion heater.

Abstract: Epitaxial layers of semiconductor materials such as, e.g., III-V and II-VI materials are deposited on a substrate under high-vacuum conditions. Molecules of a compound of a constituent of such material travel essentially line-of-sight towards the substrate admixed to a carrier gas such as, e.g., hydrogen. For III-V layers the use of compounds, such as, e.g., trimethyl- and triethylgallium, trimethyl- and triethylindium, triethylphosphine, and trimethylarsine is advantageous and economical in the manufacture of electronic and opto-electronic devices.

Abstract: Prepregs can be prepared by impregnating reinforcement materials such as glass, carbon or plastic (in the form of fibers or nonwoven or woven materials) with a solution of a polyepoxy resin and a polyamine as a hardener and subsequent drying. For the manufacture of storage-stable prepregs based on polyepoxy resins, 1,3,5-tris(3-amino-4-alkylphenyl-2,4,6-trioxo-hexahydrotriazine with a C1- to C4 alkyl radical is used as the hardener. The new method leads to storage-stable prepregs and assures that composite materials, especially circuit boards, manufactured therefrom meet the requirements for these materials.

Abstract: An improved, more economical mold (12) for use in continuously casting metals or alloys comprises a mold tube (40) and a pair of flanges, one flange peripherally disposed of and in abutting, liquid sealing relation with each end of the tube. Such sealing relation is preferably provided by a continuous knife-edged protrusion (66) formed in and disposed peripherally of each flange and adapted to sealingly cooperate with a continuous shallow groove formed in and disposed peripherally of each end of the tube. Cooling means including a jacket and a baffle surround the tube between the flanges, and the baffle (70) further defines a channel immediately circumjacent a substantial portion of the outer surface of the tube for directing a flow of cooling liquid about the tube in direct contact with such surface. Removable assembly means releasably interconnect the two flanges (50, 60) and the baffle disposed therebetween in such a way as to clamp each of the flanges to its respective end of the mold tube, thus effecting both liquid-tight seals as well as creating a unitary assembly. Accordingly, an efficient method for repairing the mold via quick dissassembly, tube replacement and quick reassembly is also provided.

Abstract: In a vehicular anti-lock control method including the steps of comparing a wheel speed with a reference value which is based on a vehicle speed estimated from the wheel speed, judging the locking tendency of a wheel from the result of such comparison and reducing a brake pressure to be applied to the wheel which is on the way to locking, a first vehicle speed is estimated based on the speed of a wheel including a driving wheel and a second vehicle speed is estimated based on the speed of a follower wheel, the driving wheel being judged to be in a racing state when the first vehicle speed is larger than the second vehicle speed above a predetermined value. When the driving wheel is racing, the first vehicle speed is held constant and as far as such racing is present the constant vehicle speed is used to determine the reference value for comparison with the wheel speed.

Abstract: Prior centrifugal concentrators for concentrating precious minerals use annular ribs or baffles to trap the precious minerals. Sand or magnetite tends to pack against such ribs, reducing the effectiveness of these devices. In the present invention, the inner surface of the rotating drum (2) is free of obstacles, but forms three continuous zones, a migration zone (A), a retention zone (B) and a lip zone (C). The precious mineral is retained in the retention zone by centrifugal force and friction while the unwanted slurry flows over the retention zone and out of the drum (2).
