LD50 for (I) is 1.2 - 2.5 g/kg (p.o. in mice). Salts of (II) with terephthalic, 4-sulphamoylbenzoic, 4-hydroxybenzoic, 2-aminobenzoic, 4-aminobenzoic, 4-aminosalicylic and 5-sulphosalicylic acids are specifically claimed.
Patent DE-2552746-A1 (DE)
Title: Vacuum drier for condenser and transformer cores - has heater to revaporise working fluid in thin film to separate contaminants
Inventor: SCHAEFER ROBERT
IPC: F26B21/14
Filed: 1975-11-25
Abstract: Condenser and transformer cores re heated for drying and de-gassing by allowing kerosene vapour to condenser on them in a vacuum chamber. The condensed kerosene dissolves oil which is present in the condensers etc., and becomes contaminated by it. To remove the oil and revapourise the kerosene a heater is in the form of a plate over which the contaminated liquid would pass in a thin film. The plate temp. would be high enough to evaporate the kerosene for re-cycling and the oil would flow down into a sump from which it would be emptied at intervals.

Abstract: A spirally wound recording carrier for storage of electrical oscillations and suitable for a video recorder has recording and playback element for several tracks. The recording carrier is wound so that it maintains an interval (a) allowing the recording or playback element to dip into a defined depth in this interval. The recording or scanning of the electrical oscillations takes place laterally on the element. Several tracks can be recorded on or played back from the carrier by displacement of the dipping depth. The interval of the recording carrier is determined by the intermediate layer of a narrower sheet. Its thickness corresponds to the interval required.

Title: Machine tool with numerical control - has total path, step coordinate and increment calculators to control process in steps along curve
Inventor: PUERZER JUERGEN DIPL ING
IPC: G05B19/4103
Filed: 1976-12-06
Abstract: The control for a numerically controlled machine tool involves a machining process executed in successive steps along a predetermined curve. A total path calculator produces its data from that supplied from points on the curve, and a step coordinate calculator calculates the step coordinates of the curve point involved in the next step, so that a dimension continually varying with the steps is always held at an actual value. An increment calculator is incorporated which calculates the advance feed increment for the next step through the difference formation between the step coordinates for the next point and those for the current point.
