Title: Self-supporting energy-supply chain which can bend on one side
IPC: F16G13/16
Filed: 1988-05-03
Granted: 1989-07-06
Abstract: The invention relates to a self-supporting energy-supply chain which can bend on one side, having two parallel rows of plate links which can pivot with respect to one another and having at least one releasible crossmember which extends between two plate links, located at the same level, of the two plate-link rows and is retained on mutually opposite plate links by screw-connection means located in its longitudinal direction. The intention is to provide a chain, the crossmembers of which impart a good degree of connection rigidity to the chain, but it being possible for at least one of the two crossmembers, located at the same level, to be easily released out of its use position and removed from the chain or, conversely, to be easily introduced into this position. For this purpose, the invention provides that the crossmember (11) can pivot outwards about an axis (T) located in the vicinity of its one longitudinal border (16), can be fixed, with the aid of the screw-connection means (24, 25), in an axis (L) located in the vicinity of the second longitudinal border (21) and, after releasing the screw-connection means and pivoting out about the first-mentioned axis (T) of the chain (K), is removed. <IMAGE>

Title: Apparatus for separating out packaging units recognised to be defective.
IPC: B65G47/84
Filed: 1988-09-23
Granted: 1990-03-08
Abstract: An apparatus for separating out packaging units, especially bottles, which are recognised to be defective and which are transported on a horizontal path of movement, the bottles to be separated out being moved approximately transversely relative to the direction of movement by a deflecting device which is accommodated in a housing and which is activated at the exact time by a recognition station for packaging units to be separated out and, in the position of rest, has a guide wall projecting into the conveying path in a wedge-shaped manner, and moreover by a deflecting device designed as a tappet movable essentially transversely relative to the path of movement. The technical problem is to design the apparatus in such a way that the bottles are diverted reliably from the first path of movement. The tappet (11) engages on a plate-shaped link (10) pivotable about a pivot axis (journal 9) fixed relative to the housing. The link (10) carries an accelerating head (16). The moment arm (17) of the accelerating head (16) is greater perpendicularly to the direction of movement of the tappet (11) than the moment arm (18) of the tappet (11) itself, in each case in relation to the journal (9). The pivot axis (9) of the link (10) is set back relative to the accelerating head (16) in the direction of movement of the tappet (11), so that, when the tappet is actuated, the accelerating head is accelerated with a component in the direction of movement of the path of movement (1). <IMAGE>

Title: Hydrogen spark igniter for nuclear power station - has spark path safety device with catalyst for controlled combustion
IPC: F23Q11/00
Filed: 1989-09-04
Granted: 1990-10-25
Abstract: A spark igniter for hydrogen has been developed for nuclear power stations, where hydrogen is released in quantities, in case of a catastrophe, into a safety container for ignition at the lowest possible hydrogen concn. The igniter causes the recombination with oxygen at low H2 concns. below the explosive limits due to a protective cap for the spark gap. A catalyst (Pd or Pt) is present and the heating of the cap caused by the catalytic combustion of hydrogen reduces the risk of chemical break-off reactions. The hydroxyl radicals produced by the catalytic combustion are utilised to raise the ignitability of the hydrogen mixt. ADVANTAGE - This is a reliable method of preventing the flame extinction and ensures the desired controlled combustion of H2.
