Abstract: A scraper conveyor comprising a conveyor chain or wire (8), which is provided with a plurality of transverse scraper disc members (10) and passes along a closed path at least partly defined by stationary conveyor channel or tube means (12) extending from a material inlet station and past one or more receiver stations, in which the material is dispensable through outlet openings in said channel or tube means, the conveyor chain or wire (8) being driven by means of a driving wheel (6) engaging with said transverse scraper disc members (10) in which the driving wheel (6) is a circumferentially substantially smooth wheel having an outer cross sectional shape (34) which conditions a frictional engagement between the wheel (6) and the wheel periphery engaging portions of the outer edges of the scraper members, means being provided for tightening the moved element of the conveyor about the driving wheel (6) sufficiently to ensure a firm frictional engagement between these parts. Hereby the driving engagement between the driving wheel (6) and the conveyor wire (8) will be entirely independent of the exact distance between the consecutive scraper discs (10), because the driving engagement is established between the smooth circumferences of the driving wheel (6) and the outer edge portions of the scraper discs (10), i.e. without specific relevance to any exact location of the rear sides of the scraper discs (10).

Abstract: A switch controller for a dynamic switch (10) responds to commands from a using system to provide control signals to the dynamic switch (10) which causes the switch to establish and breakdown paths between sources and destinations in the using system. The controller includes a plurality of command registers which are temporarily assigned to a command source for receiving command signals, decoding said signals and providing control signals to the switch for establishing or breaking down a switch path. The controller may if desired provide an echo to a selected destination so that proper execution of commands may be ascertained. After the commands are completed the control register is released for reassignment to another command source while an established switch path remains intact. Thus, commands may be received from any source for controlling the switch.

Abstract: The impervious sealing and the production method for it make it possible to replace the expensive methods of shield tunnelling or freezing and as a result eliminate interference with the ground-water balance and prepare the ground masses to be excavated in such a way that they can be continuously excavated in timed sequence with the subterranean construction from a secured position and in the dry. This is achieved by virtue of the fact that the impervious sealing consists of an elastic sealing jacket (3) which is formed from sealing walls (2) arranged in the form of a canopy, screen, housing or the like and which hermetically seals off the ground masses (5) to be excavated from the ground water (4) and/or from air. In the production method provided for this, the ground masses (5) in place of a site to be driven dry are sealed off from the ground water (4) and/or the air by a sealing jacket, are dewatered, are compacted under the pressure of the ground water (4) in place on the outside of the sealing jacket (3) and/or are stabilised by applying a vacuum. <IMAGE>

The platen assembly 106 provides for a plurality of variable-volume mold cavities 7. In one embodiment, enlarged mold cavities 7 receive plasticized resin from the screw injection assembly 101, and compression of the injected resin is provided by the toggle clamp assembly 102. In another embodiment, the platen assembly 106 includes a floating die assembly wherein pressure created by injected resin causes die inserts 5 and support pillars 15 to slide relative to a molding plate 74. Compression in this embodiment is also preferably provided by the main toggle clamp assembly 102. Preferably, the toggle clamp assembly 102 provides multiple-stage compression of the resin to first redistribute the resin and vent the cavities and, second, compress the resin to compensate for cooling-induced shrinkage thereof. In the multiple cavity embodiment, because all cavities 7 are equally compressed simultaneously, control of the molding process and balancing of the mold are readily accomplished. The method and apparatus are particularly well suited for molding optical lenses and disks. Printed circuit substrates can also be molded thereby.
