Title: Resistance welding wires to connector - to cause wire enclosure by fused connector material
Inventor: BABIEL GERHARD DIPL ING
IPC: H01R43/02
Filed: 1991-07-10
Abstract: Conductor wires are resistance welded to a connection element by current passage and counter-electrode pressure on the parts fixed together in approximately the final position in a channel-like recess of the anvil of a pressure welder. The welding pressure and current density are selected such that the low melting material of the connection element (2) melts at the interfaces with the wires (1) and thus encloses the wires. Pref. the welding duration is pref. 30-200 (esp. 80-150) millisecs. and the current density, current passage duration and the electrode pressure are controlled to provide partial melting of the connection element material, heat removal through the electrodes ensuring that the material does not melt at its electrode contacting face. The connection element (2) is pref. a brass contact sleeve which has an increased thickness in the region of the electrodes and which has a lower melting temp. than the wires (1). Pref. the upper counter-electrode (4) only contacts the wires (1) and the anvil (3) only contacts the sleeve (2). USE/ADVANTAGE - The process is useful for welding leads to contact sleeves e.g. in plug connectors. It produces a permanent weld joint and combines the advantages of soldering and welding processes in a simple manner, without requiring additional solder or flux

Patent DE-4141108-A1 (DE)
Inventor: BENCKERT HARTMUT DR ING
IPC: F04B49/08
Filed: 1991-12-13
Abstract: An initial pressure governor for a main pump (11) designed as a variable displacement pump of a compression unit (10) that supplies a hydraulic consumer (54) has a pump capacity regulator (12) controllable by means of a regulating cylinder (13) driven by alternatively applying and reducing a pressure in a driving chamber (18). A pressure regulating valve (21) for applying and discharging the pressure is driven by the initial pressure of the pump and above a minimum pressure determined by a restoring spring delivers an initial pressure that increases with a control pressure coupled into its control chamber (27). The restoring spring (32) of the pressure regulating valve (21) is set at a restoring force that corresponds only to a small fraction of the maximum control force that can be generated by the control pressure. The pressure regulating valve (21) is provided with an additional control chamber (31) which, when a pressure is applied thereon, is capable of generating an additional restoring force whose maximum value corresponds at least approximately to that of the control force. The pressure coupled into the restoring chamber (31) is derived from the initial pressure of the main pump by means of a hydraulic retarder (36, 34).
