Title: Synchronisation of generator with power network - uses lever detector and delay elements in logic circuit operating on frequency and voltage digital signals
Inventor: HOLWECK PETER DIPL ING
IPC: H02J3/42
Filed: 1976-10-05
Abstract: System and generator voltage are connected through transformers to a summing amplifier and also to independent channels all of which pass through level detectors and delay elements to form inputs to an AND-gate. A further circuit compares system and generator frequency and forms the fourth input to the AND-gate. the voltage and frequency difference signals form negating logic inputs. The two voltage signals give positive inputs when above a set threshold. Thus when voltage and frequency difference errors are within limits, and the actual voltages are of sufficient magnitude the circuit breaker is released for closing. The circuit avoids the use of relays and moving apparatus, which for example due to wear, can develop synchronising errors.

Title: Electrode plate for lead-acid accumulators - has tubes filled with active material and sealed by polyester resin
Inventor: SCHULTE KARL-HEINZ
IPC: H01M4/76
Filed: 1977-02-26
Abstract: An electrode plate with tubes, filled with active material, for lead-acid accumulators requires during the attachment of the closing strips no force application to the tube sheaths or to the lead rods inside them, which could cause damage. The closure nevertheless prevents any active material from falling out of the tubes. This has been achieved by laying the tubes in a split two-part casting mould which leaves a 5mm cylindrical space at the end of each tube. Each space is linked to the adjoining ones by cut-aways of the webs. The spaces and the webs joining them are then filled up by a casting-type of polyester resin. Pref. resin is a two-component polymethyl methacrylate resin which has adequate resistance to sulphuric acid and improves the adhesion between plastic fabric of the tube and the closure.
