Abstract: In an ink supply apparatus, inks of a paste-like consistency are supplied from a cylinder to a chamber doctor blade disposed adjacent an inking roller. Two conduits are disposed at opposite ends of the chamber doctor blade and each conduit communicates with one of the two opposite ends of the cylinder. Ink is supplied to the cylinder through an aperture. Within the cylinder there is disposed a reciprocating piston which, at low speed, forces ink via the conduits to the chamber doctor blade.

Abstract: An arrangement for the oriented feeding out of caps provided with pull-lugs comprises a disc which rotates at high speed, and onto the planar working surface of which the caps are dropped. By the rotation of the disc the caps are moved to the periphery of the disc where they contact a guide rail in the form of an uninterrupted ring which is arranged at such a distance above the surface of the disc that the cap is allowed to project beneath the guide rail. However, the lug on the cap prevents the cap from wholly passing under the guide rail. At a point along the ring periphery a radially movable feeding out element is provided which engages the passing caps and withdraws them via the space between the disc and the guide rail, with a short-time deformation of the pull-lug.

Abstract: A capping machine of the rotary type for closing filled bottle type packing containers for beer or other liquids which are made from a plastic material includes a lower wheel on which the bottles to be capped are placed and an upper wheel which supports closing rams which are movable vertically towards and away from the bottles by means of a cammed track. Caps loaded into a magazine are transferred one by one to the rams as the wheels turn, and the bottles are capped as the ram moves downward onto the bottle mouth.

Abstract: A relay matrix, especially a reed relay matrix for selectors in telephone exchanges, consists of a crossing point network, i.e. relays arranged in rows and columns constituting switching elements of speech paths, control unit and holding units common to such a network. The relays of the crossing point network are of the monostable reed-relay type. The through connection is of the two pole type i.e. each crossing point comprises just two make contacts. The wire connection between the matrices in the selector is limited to the speech wires since a continuous holding wire is not utilized. Addressing of the crossing points in a connection is carried out by means of a central processor by the setting up of a connection as well as by the releasing of the connection.

Abstract: In a relay matrix there are provided a plurality of control and holding circuits for selecting which of the relays are to be energized. The control and holding circuits which are associated with groups of relays include two-state devices which are triggered into a conductive state at the coincidence of a control signal and a minimum value control current and remain in that state after the termination of the control signal until the control current falls below the minimum value.
