Abstract: A method for manufacturing a semiconductor device includes a step of forming a plurality of semiconductor pellets in substantially a matrix form in a semiconduc­tor wafer (13) and processing the same. A group of large-sized semiconductor pellets (12) are formed in a matrix form in the central area of a semiconductor wafer (13) and a group of small-sized semiconductor pellets (14) are formed in an area between the periphery of the semiconductor wafer (13) and the group of large-sized semiconductor pellets (12) which is not used in the prior art, thus forming the semiconductor pellets (12 and 14) of different sizes in the semiconductor wafer (13). First, a dicing operation is effected to separate the large-sized semiconductor pellets (12) from the small-sized semiconductor pellets (14) and then each group of the large- and small-sized semiconductor pellets (12 and 14) is diced into individual semiconduc­tor pellets.

Abstract: As shown in Figure 2, a teletext decoder has a multi-page memory (MEM) comprising a plurality of memory portions (CH0 to CH3) in which individual pages can be stored on a priority basis. The numbers of selected pages are entered into page request registers (PR0 to PR3) and when the number of a selected page is detected by the relevant one of page comparators (PC0 to PC3) a found bit (FB) is produced by the relevant one of flip-flops (FB0 to FB3) and recorded in the memory portion allotted to the selected page by processor means (PM). In order to ensure that the end of a selected page can also be detected, one of the memory portions is allotted to store every page received so that a found bit is always produced at the end of a selected page stored in another memory portion. The processor means (PM) uses this latter found bit to signify detection of the end of the selected page.

Abstract: Ruminants are fed a water-insoluble polymer, which may be swollen (i.e. having absorbed water to form a gel) or unswollen. At least 0.04 kg of (swollen) polymers per day per 100 kg body weight is administered, and the polymer has not necessarily been used as a substrate for the preparation of feedstuff. 
     Such methods are particularly advantageous when the animal is being fed on a diet causing acid conditions in the rumen, such as a diet of silage. 
     A useful polymer is ammonium polyacrylate cross-­linked by about 500 ppm MBA. 
     The polymers enhance feed conversion rates and hence lower the effective cost of feeding the animals.

Abstract: A closure for sealing a circular opening in a pipe or vessel (2) is provided comprising a closure body (1), a plurality of arcuate locking members (5) mounted on the closure body and movable between released and engaged position. An operating member (6) which may be moved angularly about an axis offset from the centre of the closure body (1) by manipulation by an operator is connected to a drive pinion (7) angularly movable so as to be therewith. The drive pinion (7) includes an eccentric drive pin (8) journaled at one end of one locking member (5). A toothed wheel (10) is angularly movable about the central axis of the closure and meshes with the drive pinion (7) and with a plurality of slave pinions (14). The slave pinions (14) are mounted one at the other end of said one locking member (5) and one at each of the ends of the other locking members (5). Each slave pinion (14) also includes an eccentric drive pin (13) journaled on the respective locking member (5). In operation movement of the operating member (6) causes movement of the drive and slave pinions (7,14) such that the drive pins (8,13) move the locking members (5) to either their released or engaged position. 
     Suitably the closure further includes a safety pressure release means (16) which interlocks with the operating member (6) and has to be released before the operating member can be manipulated to open the closure. A further safety feature against residual pressure   consists of a safety latch (18) which limits the opening movement of the closure.

Abstract: A marking device comprising a marking roller 15 which can be placed by a swivelling movement against the moving sheet-metal strip 11 to be marked contains, in a known manner, two further rollers 16 and 17 for the wetting supply of the marking fluid to the marking roller 15. All three rollers can be moved against adjustable stops 35, 36 and 37 by pneumatic cylinders. The adjustable stops, which are seated on the mountings of the rollers, are preset in an alignment pedestal 51 used as an auxiliary device, in such a way that, when inserted into the marking device, the rollers are in the correct working position without readjustment. The three rollers 15, 16, 17 are driven at the same peripheral speed by a toothed belt. By virtue of the swivelling movement of the rollers during the return stroke of the pneumatic cylinders, the rollers are separated from one another and from the sheet-metal strip 11 and, in addition, the marking fluid 18 is tipped out of the tray 19, into which the dipping roller 17 dips, via an overflow 38. <IMAGE>

Abstract: A description is given of an echo canceller with an adaptive filter (15). The adaptation rate of the adaptive filter (15) is controlled by a control unit (29), which determines the associated control signal from its input signals (x(k), u(k), e(k)). If the described echo canceller is used, for example, in the speech installation of a telephone network, the adaptation process may only take place if the remote subscriber speaks, and the near subscriber is silent. If such a decision is taken automatically by means of the corresponding signals (x(k), u(k)), a defective decision can substantially reduce the quality of the installation, at least temporarily. 
<??>For this reason, it is provided to control the adaptation rate of the adaptive filter (15) of the control unit in a sliding manner as a function of suitably selected mean values of three signals (x(k), u(k), e(k)) when the remote subscriber speaks.
