IPC: H04Q11/04
Filed: 1988-02-15
Abstract: The circuit arrangement is intended to provide the possibility of relieving exchanges of a communication network, used both for dial-up connections and for tie lines, with respect to the administrative expenditure for the subscriber facilities included in tie lines. The circuit arrangement exhibits a multiplex arrangement (M2) connected to an exchange (VS) of the communication network and exhibiting a multiplicity of transmission channels. Subscriber facilities which are included in dial-up connections or tie lines extending via the exchange via the multiplex arrangement are connected only to a fixed number of transmission channels. The remaining transmission channels, which can be optionally connected to one another, are provided for connecting subscriber facilities which are only included in tie lines extending via the multiplex arrangement with respect to one another. The circuit arrangement can be used for connecting subscriber facilities, used for receiving and/or outputting digital communication signals, to a communication network used both for dial-up connections and for tie lines. <IMAGE>

Abstract: A ram for a press, comprising an hydraulic piston and cylinder arrangement (10,22) which is operated by the application of pressure to hydraulic fluid in a region of the hydraulic chamber (16) within the cylinder (10) which is on one side of the piston (22). Hydraulic fluid is free to flow into and out of the said region until the hydraulic piston (22) nears the end of its stroke. The bottom end (44) of the chamber (16) is narrowed, to cut off such flow at that point, so that subsequent application of pressure to the hydraulic fluid in the said region effects a movement of the hydraulic piston (22) under the full operating force of the arrangement (10,22).

Abstract: A beam of light emitted from a light source (11) and then modulated is focused through a write head (14) onto a surface of a substrate (15) which is coated with a photosensitive material and is rotated at a predetermined constant rotational speed. The write head (14) and the substrate (15) are displaced relatively in the radial direction of the substrate (15). While an optical axis of the beam of light is displaced in the direction in which the relative displacement speed between the write head (14) and the substrate (15) is decreased or increased, the substrate (15) is exposed in such a way that a locus of a first turn or wind of predetermined tracks or pit arrays is recorded. Thereafter, while the substrate (15) is rotated at the constant rotational speed, during the next rotation of the substrate the projection of the beam of light is interrupted and the optical axis of the beam of light is returned to its initial position. The above-described steps are repeated for recording the succeeding tracks or pit arrays, whereby a desired track pattern can be obtained.
