Title: Solid state exposure control cct. - has differential amplifier to eliminate leakage currents in photocells
Inventor: TUNEKAWA TOKUICHI
IPC: G01J1/44
Filed: 1974-10-10
Abstract: Cadmium sulphide photocells suffer from poor response w.r.t. silicon photodiode arrays although they do not suffer from large leakage currents which generate false exposure readings at low intensities. The invention provides a compensating circuit for silicon blue cells in which a differential amplifier coupled to a variable resistance determines the leakage current through the photocells and balances this out by a variable dark current. The subsequent output of the system is amplified by an operational amplifier, of which the variable resistance is part. An embodiment of the invention thus ensures a linear pattern of the photo current dependent on the lighting strength even when the latter is poor.

Title: Injections against magnesium tetany in ruminants - contg. a basic magnesium salt of acetylglutamic acid
Inventor: SCHROEDER WOLFGANG DR MED
IPC: A61K31/70
Filed: 1974-11-15
Abstract: In Ca- and Mg-contg. injection- or infusion solns. against magnesium tetany (hypomagnesaemia) in ruminants, the Mg is present as a basic salt or acetylglutamic acid. The solns. are used against magnesium tetany, such as field-, stable- or transport tetany in ruminants esp. cattle. They re-instate the acutely disturbed ion-equilibrium in the blood so that acute symptoms quickly disappear. They also remove excess NH3, caused by eating spring grasses, via the urea cycle. The N-acetylglutamate present stabilises the enzyme protein necessary for the reaction of excess NH3 with ornithine to form carbamylphosphate with enduring effect. The solns. are very well tolerated and have no side-effects on heart and circulation.
