Abstract: A hydrophobic silica is prepared by mixing and heating a mixture of (a) 100 weight parts wet-method silica and (b) 1 to 100 weight parts organopolysiloxane represented by the following average unit formula R¹ a R² b SiO (4-a-b)/2 , wherein R¹ is a monovalent hydrocarbon group, R² is the hydrogen atom,  a  is from 1 to 3 inclusive, and  b  is from zero to 1 inclusive, with the provisos that  a  +  b  is from 1.90 to 2.10 inclusive and  b /( a  +  b ) is from zero to 0.45 inclusive. This hydrophobic silica is used to prepare a high-strength silicone rubber particulate by mixing with a curable diorganopolysiloxane and curing the mixture in the form of particulates. A preferred manner of making the particulates is by emulsifying the mixture of hydrophobic silica and curable diorganopolysiloxane in water, then spraying the emulsion into a hot gas to cure the silicone rubber composition and remove the water, giving microparticles of high-strength silicone rubber.

Abstract: This invention relates to a method and apparatus for the selective electroplating of metals on metal or metallised products in an elongated strip. Use is made of an apparatus in which an assembly of a masking belt (15) and the product strip (16) are guided along means for exposing the products to an electrolyte. Masking belt and product strip have been provided with holes distributed in a regular pattern over their respective length's, whilst driving means are provided to lengthwise transport masking belt and product strip. By means of proximity sensors (27,28), signals are obtained which indicate the position of the holes in the masking belt and product strip in positions which, related to the direction of travel of belt and strip are situated up stream and nearby the means for exposing the products to an electrolyte. 
     When the signals obtained from the proximity sensors indicate a deviation from the targeted position of belt and strip in relation to each other, a relative move between masking belt and product strip lengthwise is effectuated by influencing the driving means.

Abstract: With the aid of known measuring vessels, which are used for receiving fluids to be examined, such as blood, blood plasma or the like, the coagulation of blood is determined mechanically. However, a photometric measurement of the coagulation is not possible with these known measuring vessels, which are provided in the centre of the circular base area with a projecting delimiting journal, since for this a complete and uninterrupted passage of the light emerging from a transmitter through the wall of the measuring vessel is indispensable. 
<??>The aim of the invention is to provide a measuring vessel with which both a mechanical and a photometric determination of the coagulation of blood is possible. 
<??>This aim is achieved by virtue of the fact that the measuring vessel (1) has a rectangular shaft (4) whose one end is of funnel-shaped design and opens into the tubular part (7) which has two parallel side surfaces (9), which in each case form a plane contact surface. In this case a foot element is connected to the tubular part (7), onto which foot element the measuring vessel (1) can be placed. 
<??>By means of this design of the measuring vessel it is now possible to carry out photometric analyses over the entire spectral region. However, at the same time the measuring vessel can also be used for examining the blood according to the ball method.

Abstract: In the case of perforated drainage concrete blocks, in particular paving blocks of various shapes and sizes, which are laid on rain-exposed surfaces, such as roads, paths, squares, carparks and tree-surrounding beds, and are filled at the lateral ends by means of pointing compounds or sand, the problem exists that the holes become blocked during the pointing or introduction of sand. To avoid this, the holes are closed at their upper end until the pointing or sand-introducing operation is complete. Advantageously, this is effected by a filling medium which can be washed away or dissolved by adding water. <IMAGE>

Abstract: The use of nonmonotonic or "common sense" reasoning has often been advocated to speed up reasoning systems. The difficulty has always been that nonmonotonic reasoning requires consistency checks, which are even more computationally intractable than the monotonic reasoning normally used in reasoning systems. Disclosed herein are methods and apparatus for making consistency checks tractable by performing them over a limited context using fast sufficient consistency checks. The results are approximate, but approximate results are expected in nonmonotonic reasoning. Included in the disclosure are techniques for selecting the limited context and making the fast sufficient consistency checks and a default reasoner which employs the techniques to check the consistency of a default conclusion with a limited context.

Abstract: Method of epitaxial overgrowth of A III B V  semiconductor on non-planar A III B V  substrate containing grooves, the sidewalls of which have an equivalent orientation to that of the substrate.

Title: Trellis coded QAM using punctured convolutional codes
Inventor: HOW STEPHEN K
IPC: H03M7/36
Filed: 1994-05-03
Abstract: Punctured binary convolutional codes are used in a trellis coded modulation scheme to achieve spectral efficiencies as high as those of multi-dimensional codes, using simple hardware. A base rate 1/2 binary convolutional code is punctured to rate n/k. The output of the punctured encoder 18 is mapped to a four-way partition (60, 62, 64, 66; 120, 122, 124, 126) of a 2 N  point two-dimensional QAM constellation. The four-way partition consists of a two-way partition in both the I and Q dimensions. The two-way partitions of each dimension are used to transmit the two level output of the rate n/k binary convolutional coder. (N-2) "uncoded" bits (24) are transmitted by selecting the unique constellation point in a partition group. The code has an average throughput of        (N-2)+2n/k           bits per symbol. The invention is also applicable to trellis coded amplitude modulation schemes based on 2 N  possible amplitude levels provided along a one-dimensional constellation.

Abstract: A variable length decoder device receives a stream of variable-length encoded data segments for successive transient storage. The storage is recurrently accessed under control of successive pointers. A decoder is fed by the storage and decodes a stream of data segments each from a respective encoded data segment. Furthermore, in step with the decoding a next pointer is produced as being directly derived from the accessing through reading of a localizer information. The latter again is produced in a preprocessor that sits before the storage, through localizing the data segments and indicating each segment by an associated localizer.
