Title: Closure assembly for a container
Inventor: POORE ALBERT C G
IPC: B65D55/02
Filed: 1987-10-21
Granted: 1991-12-10
Abstract: SPECIFICATION "A CLOSURE ASSEMBLY FOR A CONTAINER"    ABSTRACT OF THE DISCLOSURE       The invention relates to a closure assembly for a container.      The closure assembly comprises a first cap portion hingedly connected to a second cap portion adapted to be positioned over the mouth of an associated container and including an aperture to permit dispensing from the container.  The first cap portion is arranged so that in one position it overlies the aperture to close the container, and in another position is lifted clear of the aperture to open the container.  The cap portions together include means so that they can be snapped together and their separation from a closed to an open position requires the exertion of a positive force by the user and the first cap portion includes at its periphery opposite its hinged connection with the second cap portion a lip which co-operates with an inwardly displaceable section of the second cap portion.  The inwardly displaceable section includes at its upper edge face adjacent the lip a portion which is associated with an outermost lower edge of the lip when the two cap portions are in a closed position and raised above that lower lip edge so that on inward displacement of the then, as displacement pressure is increased, forces the lip upwards.  In that manner the snap action of the two cap portions can be overcome and the closure opened.

Abstract: Process of casting steel from a ladle into a tundish, in which the metal which is in the tundish is protected against oxidation and nitridation. The process comprises two consecutive steps: a first step which includes flushing the tundish before the start of the casting of the liquid metal during which a high flow of dry ice or liquid argon is introduced until the oxygen concentration in the vicinity of the zone corresponding to the base of the jet of liquid metal at the start of the casting is lower than about 0.5%; and a second step for the upkeep of the atmosphere in the vicinity of the base of the jet which begins when the liquid metal starts to flow in the tundish, during which dry ice or liquid argon is injected as an upkeep flow which is less than the flushing flow, so as to maintain an oxygen concentration lower than about 0.5% in the vicinity of the base of the jet.

Inventor: GEIGER GERHARD
IPC: H04M11/06
Filed: 1988-10-17
Granted: 1997-11-04
Abstract: The invention describes a system architecture for a digital switching system in which signalling and packet data are exchanged between terminal stations (E) and a superordinate unit (PAD) without collision and without loss of data.  In a subordinate unit (LCi), data flowing in the direction of the superordinate unit (PAD) are separated and signalling data are preprocessed.  Signalling and packet data flowing in the direction of the terminal station are switched on the same data channel and,  with the aid of a monitoring facility, a control signal characterizing the state of the data channel is passed on to the superordinate unit (PAD).  The architecture is modular and can thus be adapted variably to different packet data volumes.

Abstract: ABSTRACT               HIGH SPEED YARN KNITTING APPARATUS     A knitting machine is described in which the elastic thread packages (26) are mounted in a stationary position away from the knitting head (22).  This results in reducing the revolving mass and the space necessary to accommodate the revolving mass.  Furthermore, the commencement o. wind on the package (26) can be left as a tail which is knotted to the free end of a second package thus permitting the machine to run continuously without stopping to change packages. A plurality of like knitting heads (22) is mounted in relatively close proximity in a single knitting head frame (24) in such a manner that chain stitches are fed   from a power driven warp beam (12, 16, 20).  Each knitting head includes yarn positioning apparatus in which yarn (12) fed to each needle (30) of the knitting head (22) is moved under tension with minimal friction to a position where the needle (30) traps the yarn (12) on its downward stroke. Embodiments of the invention are described.
