Patent EP-0294012-A2 (EP)
Inventor: BOISSON DE MARCA JOSE ROBERTO
IPC: H04N19/94
Filed: 1988-02-11
Abstract: A method for resisting the effects of channel noise in the digital transmission of information by means of the technique known as vector quantization, in which the codebook for binary index code assignment is generated by picking a vector quantized codeword with high probability and low perceptually-related distance from a required group of nearest neighbors, assigning that codeword and those neighbors binary index codes differing only in one bit, repeating the steps just outlined for assigned binary index codes to residual codewords until the lasts assignments must be made arbitrarily. Applications include transmission of speech by coded LPC parameters and transmission of image intensity or chrominance blocks for visual images. Such systems also make possible and are attractive for memory-efficient storage of such signals.

Abstract: An apparatus for suppressing noises in a color video signal is constructed to extract a frequency band component of the color video signal using a variable pass-band filter (3), to limit the amplitude of the extracted frequency band component using a variable amplitude limiting circuit (5). and to subtract the component, which is limited in amplitude, from the color video signal. Thus, a beat component such as a beat component generated by the interference between the main carrier signal and the color carrier signal of a recording video signal is removed from a video signal obtained after demodulation.

Abstract: In a reciprocating piston internal-combustion engine comprising a double overhead camshaft cylinder head, the latter has combustion-chamber inlet and outlet valves arranged around a spark-plug well arranged in the cylinder axis, split bearings for the respective camshaft being provided between the obliquely suspended inlet and outlet valves. To obtain a combustion chamber for high output in combination with low consumption, with valve timing gear tailored to optimum gas exchange in combination with a cylinder head of narrow construction, it is proposed that a bearing cover common to the two camshaft bearings be secured via a projection bounding the well and that the cams of each camshaft on both sides of the bearing cover be of conical configuration, the cams, matched in their distance from one another to a small centre distance of the camshafts, acting on valves whose axes intersect at a point of intersection whose distance from the combustion chamber boundary on the cylinder head side is a multiple of the diameter of the cylinder bore.

Abstract: A transducer (78) measures the angular relationship between a drive member (112) and a driven member (100) throughout a range of relative angular positions therebetween. The transducer provides a signal indicative of that angular relationship, and the signal can be transmitted to a controller (140) that regulates the torque applied by the drive shaft. The transducer can be used in a web spooling apparatus where the position of the driven member relative to the drive shaft during web winding operation is a function of tension transients in the web. The transducer enables the system to adjust the torque of the drive shaft as a function of the angular relationship of the driven member and drive shaft so that the system can reduce tension transients in the web being wound onto the spool.

Abstract: In order to reduce the loss of data packets, it is known to provide buffer stores, priority circuits and devices for traffic measurement. All this must be present in each switching stage, in most cases once per input line. It is intended to reduce this high expenditure within the switching network. According to the invention, the incoming packet streams are converted into synchronous time-division multiplex data streams with fixed association between time channels and individual connections. Switching can then be effected in synchronous time-division multiplex techniques. The switching network is of simpler construction but must be slightly overdimensioned. <IMAGE>

Abstract: 2.1 With conveyor bottoms (10, 12) which oscillate in opposite directions and which can experience a lateral inclination, there are guide plates (14, 16) which are intended to prevent the material on the conveyor bottom (10, 12) from slipping towards the downhill side. However, a weak point proves to be the transition between the two conveyor bottoms (10, 12) when the guide plates (14, 16) move away from one another and the conveyed material accumulates in a gap formed between these. The flow of material is thereby disrupted and the guide plates (14, 16) are damaged when they move up to one another again and the gap formed between them is blocked. 2.2 To solve this problem, the guide plates (14) located upstream are so designed that they overlap the downstream guide plates (16) in a roof-shaped manner at least over part of their length. 2.3 Such an arrangement of guide plates (14, 16) is found especially in combine harvesters. <IMAGE>
