Abstract: MULTIPLE IMPLEMENT HITCH AND TRANSPORT         Abstract of the Disclosure A two-wheeled trailer hitch supporting two three-point hitch mounted implements side-by-side for field operation.  The implements are mounted on outriggers which are foldable forwardly to narrow the unit for transport.  A pair of rigid diagonal drag links movable fore-and-aft by a cylinder-activated slide block is connected to the outriggers for pivoting them approximately ninety degrees between the field and transport positions.  Lift frame structures selectively engage the three-point hitch linkages to raise the implements on the respective outriggers.  The lift frame structure is disengaged from the linkages when the implements are lowered for greater flexibility in the field-working position.

Abstract: ABSTRACT       Connectors for terminating and splicing high voltage power cables comprise a metallic tubular sleeve having an open end for receiving an electrical conductor and a closed end.  The inner wall of the sleeve is pretinned.  The sleeve can be provided with a slug of solder proximate to the closed end.  A connection is made by inserting the conductor into the sleeve, heating the solder, and as the solder melts, relatively moving the connector and the conductor toward each.  The connector can be provided with an insert to accommodate conductors that are non-circular in cross-section.        The connector can be provided with means for pressuring the slug of solder toward the open end of the sleeve at the temperature at which the slug of solder melts. With this connector, no relative movement between the conductor and the connector is required. Merely by melting the solder, the means for pressuring causes the solder to extrude around the conductor.

Abstract: ABSTRACT:     The invention relates to a telecommunication system, in particular to a telephone system comprising a plurality of intercoupled sub-systems.  Each sub-system comprises a control-unit and at least one peripheral module to which communication lines can be connected.  A problem involved is that when establishing a connection between two terminals connected through the communication lines to the system a large number of data has frequently to be passed from and to the terminals.  According to the invention the data management becomes more effective and more economic when the control-unit of each sub-system comprises a list of numbers inside the system and that on the basis of a number of a desired destination connected to a communica-tion line provided by a source connected to a communication line it is determined to which sub-system the destination is associated.  When the destination sub-system is a system differing from the source sub-system, the required (signal-ling) information about the identity and characteristic of the source is transmitted to the control unit of the des-tination sub-system, whilst the connection is passed on to the destination sub-system.  The control-unit of the des-tination sub-system then analyses the information and establishes the connection, as the case may be.
