Abstract: This invention is for a metallocene compound which can be used in a catalyst system to produce hemiisotactic polymer. The compound is a bridged metallocene compound having dissimilar cyclopentadienyl groups and no bi-lateral symmetry. One example of the compound is isopropylidene(3-methylcyclopentadienyl-1-fluorenyl) zirconium dichloride. The catalyst of this invention can be converted to an ionic metallocene catalyst by an ionizing agent, such as methylaluminoxane. 
     The polymer produced with this catalyst is characterized by having an isotactic structure effecting only every other asymmetric carbon atom. In the case of polypropylene, every other methyl group is on the same side of the principal polymer chain as represented by a Fisher projection. The remaining methyl groups can be either on the same side or on the opposite side of the principal polymer chain. The polymer produced with the catalyst of this invention can be used as a plasticizer.

Abstract: Starting point: The sequence is known of a copying switching matrix, a distribution switching matrix and a destination switching matrix on the one hand, and on the other hand a switching matrix in which copying can be carried out in every stage. 
<??>Technical problem: Real operation is a mixture of point-to-point connections, point-to-multipoint connections with few branches and point-to-multipoint connections with many branches. The overall traffic and its individual constituent parts are constantly changing. The known structures are optimised in each case for one specific traffic type in one direction only. 
<??>Fundamental concept: The switching elements of a switching matrix which is optimised for point-to-point connections contain the additional facility for copying a small number of input signals for any number of outputs, whereby a very large number of copies can be achieved overall for a very small number of input signals. This switching matrix is supplemented by a copying switching matrix, which serves solely to produce in each case a limited number of copies for a large number of input signals, which are then switched in the (main) switching matrix as point-to-point connections. 
<??>Solution: Point-to-point connections are operated as "connectionless connections" by means of automatic switching element control. It is ensured that these connections act outwardly as virtual connections. Point-to-multipoint connections are also operated in the main switching matrix as virtual connections (connection-oriented) by means of connection tables. 
<??>Advantage:Interference-free rearrangement of existing virtual connections possible. Very even utilisation of the (main) switching matrix as a whole. 
<??>Disadvantage: Switching elements with two different addressing facilities required.

IPC: G06F7/52
Filed: 1991-06-27
Abstract: A method and apparatus makes rapid frequency measurements by measuring time intervals for a series of blocks of event counts with the number of events in each block held constant. This makes the numerator of the events/time relationship constant so it does not have to be measured, processed or stored. The frequency of the signal is determined by measuring the time interval, then taking the inverse of the measured value and multiplying by the appropriate constant. A fast inverse circuit uses a Taylor series expansion technique implemented in digital circuitry, with the slope resolution adjusted for regions of small slope to improve accuracy.

Abstract: 5 n 7  The film and the PS plate are read in separately by a scanner to recognize the positional shift therebetween. Based on the quantity of the recognized positional shift, the alignment in position is conducted between the pair of image information. For the alignment in position, the address conversion is applied most preferably as the method. Both the images are compared in such a condition as being aligned in position, and the comparisons are made one by one for fixed regions. The whole image is divided into a plurality of images having a fixed area. Next to this, for each divided region, a judgement is made on whether each divided region is formed of halftoned portion or text. As a result, if a divided portion is determined to be a text, a fixed threshold level for binarizing is set up. When a divided portion is judged as a halftoned portion, a threshold level is set up, what is called dynamically, in accordance with variations of the halftone dot densities. Then, based on the set-up threshold levels, each portion is binarized. After these binarizing operations, all regions of the film divided are respectively compared with the corresponding regions of the PS plate to detect any mismatched portions. It is most preferable to compare the numbers of black (or white) dots since this method agrees with the human's sensation. As a result of the disagreement detection, a judgement is made on whether or not each divided portion disagrees with the corresponding portion more largely than a certain level, if it is so, the region in question is determined as a mismatched one and the error information is set up.

Abstract: A hybrid electrical optical connector is described employing a push-pull plug receptacle combination. A hood structure (22) protruding from the plug component (14) of the connector simultaneously serves to ensure that the plug (14) is properly rotationally oriented with respect to the receptacle (12) prior to insertion, that the individual terminals (20,18) are guided toward the respective terminal receiving channels (28,26), and that the plug (14) is latched in place once fully engaged. A rigid armature (46) allows the plug (14) to be partially assembled and tested prior to final overmolding. In its final overmolded form the plug (14) is impervious to the influx of contamination and can withstand a substantial amount of physical abuse. The inexpensive materials used in the construction of the plug (14) and the ease of assembly yield a low cost plug (14) well suited for use in conjunction with a disposable peripheral device.
