Patent EP-0361763-A2 (EP)
Inventor: BECKETT CHRISTINE ANNE
IPC: D21H17/28
Filed: 1989-09-19
Abstract: A composition for flocculating paper- or boardmaking filler comprises particles of starch, in aqueous suspension, and a flocculating agent, eg. a polyacrylamide. Preflocculated filler for addition to a paper- or boardmaking stock may be prepared by adding such a composition to an aqueous slurry of filler particles, eg. calcium carbonate. The use of particulate starch that is insoluble in water at temperatures normally encountered in the wet-end of a paper- or boardmaking process, in particular temperatures below 35°C, obviates the need for a preliminary solubilisation step. However, the starch is soluble at temperatures encountered in the drying stage of the paper- or boardmaking process, where a starch solution is formed which is distributed through the paper matrix and imparts thereto additional strength.

Abstract: A semiconductor device having an internal wiring layer (123) which functions as a transmission path in a package (100), the internal wiring layer comprising a fine wiring portion (131) for allowing a many-pin structure of the semiconductor device and a low electric resistance wiring portion (133) for decreasing the internal wiring resistance. For the fine wiring portion and the low electric resistance wiring portion, two grounding layers for individually forming a micro strip structure are disposed. Alternatively, a grounding layer (115) for forming the fine wiring portion in a micro strip structure and another grounding layer (111) for forming the low electric resistance wiring portion in a coplanar structure are disposed. By considering the distance between these grounding layer and each wiring portion, the characteristic impedance of the entire internal wiring layer is controllably kept constant.

Abstract: The mould exchanging apparatus, serving a plurality of plastic injection moulding machines, comprises an exchanging table (27), which serves as transporting carriage and can be moved in a linear guide (45) to a depot (44) for injection moulds as well as to the plastic injection moulding machines, aligned in parallel with the guide (45), in connecting position for the mould change. Two mould receiving places are arranged one behind the other on a rotatable carrier plate (27h) on the exchanging table (27). In the connecting positions, mould guides (G") of the receiving places, with the carrier plate (27b) turned if need be, form alternately with a mould guide of the mould clamping space of a plastic injection moulding machine and alternately with a mould guide of a depot receiving place (44a) transport tracks for the exchanging of an injection mould. It is achieved by such a design that the injection moulds of an entire group of plastic injection moulding machines can be exchanged fully automatically with the exchanging table (27), provided that the said machines are arranged in a space-saving manner with respect to the mould depot (44). This arrangement avoids running over the operator sides of the plastic injection moulding machines, and consequently the operator, following an upright transporter. <IMAGE>

IPC: G06F15/78

Abstract: A data processing system that accesses different sets of processor - I/O storage registers as a function of access mode control signals from a processor. A decoder associated with the registers receives signals from the CPU indicating that data stored in single byte of multiple byte registers is to be transferred. When these signals indicate that X-byte wide data is to be transferred, one of a set of X-byte wide registers are addressed. When these signals indicate that Y-byte wide data is to be transferred, access is diverted to the Y-byte wide registers. The decoder also decodes these signals to determine which of the Y-byte wide registers is to be addressed in that particular cycle. This system is particularly suitable for processor - I/O applications wherein the serviced adaptor card has limited register access to communicate with the processor.

Abstract: Page management mechanisms provide candidates for page stealing and prefetching from a main storage data cache of shared data when the jobs sharing the data are accessing it in a sequential manner. Pages are stolen behind the first reader in the cache, and thereafter at locations least likely to be soon re-referenced by trailing readers. A "clustering" of readers may be promoted to reduce I/O contention. Prefetching is carried out so that the pages most likely to be soon referenced by one of the readers are brought into the cache.

Abstract: In a process chamber (12) having a gas inlet (16) and a gas outlet (18) for generating a generally upward-directed gas stream (E), a hollow lance (40) extends transversely to the general gas stream (E) between two pairs of baffles (42, 44). The lance (40) has a profile, which is symmetrical to a vertical centre plane (A), and contains a conveying channel (60) which extends in the longitudinal direction of said lance and to which material discharge nozzles (80) are connected. Above the baffles (42, 44), a pair of half-shells (52) is located which, together with the baffles (42, 44), form a straight trough (53) which is at least approximately symmetrical relative to the centre plane (A). Between the gas inlet (16) and gas outlet (18), a pressure gradient can be established, which creates a straight-line fluidised bed (F) within the trough (53).
