Patent DE-4033437-A1 (DE)
Title: Machine for trimming catalogues, books, etc. -  has four bar chain mechanism driving side blades to direct cutting motion towards catalogue spine
Inventor: ISRAEL GERD-REINER DR ING
IPC: B26D1/09
Filed: 1990-10-20
Abstract: The machine forms part of a high speed production line. The stack of catalogues (3) is automatically transferred to the table and clamped in position. In one machine cycle two side blades (6) descend in a slicing cut to trim the top and bottom edges and, as the side blades start to move back after completing the cut, the cross-blade (4) moves downwards to trim the remaining outer edge of the stack. By the use of a four bar chain mechanism (13,14,15,21,28) in the driving linkage to the side blades, the motion of the blades during cutting (22) is directed towards the spine (31), of the catalogues, thus avoiding a tendency for sheets to tear from the staples. ADVANTAGE - High quality of cut and reduction of rework. Improved productivity.

Title: Oxytocin for treatment of juvenile type I diabetes mellitus - increases prodn of tyrosine and adrenalin, necessary for glycogen mobilisation
IPC: A61K38/095
Filed: 1992-09-04
Abstract: The new medicament "Oxytocin" is for the treatment of diabetes mellitus type I patients who have none or insufficient oxytocin in the blood. The presumption that the low sugar level owing to a low adrenalin level is caused by an insufficient production of tyrosine. Tyrosine production is dependent on oxytocin. Therefore administration of oxytocin will produce tyrosine and hence adrenalin. Adrenalin should then mobilise glycogen for an increase in the blood sugar level causing the secretion of insulin. USE - Oxytocin is used for the treatment of juvenile type I diabetes mellitus. The blood sugar level is thereby increased to 80 to 120 mg/100 ml so that insulin is produced for the removal of blood glucose.
