Title: Carbon silicon oxide phosphoric acid (-salt) coating for - hot foundry moulds
Inventor: DAVID SHARP JOHN
IPC: B22C3/00
Filed: 1969-09-12
Abstract: Casting-moulds, at any temps but particularly at 450-800 degrees C, are coated, preferably by spraying, with a carbon or carbon-containing material (graphite, ground coke or -peat, particle size mainly below 0.152mm) in a binder of colloidal silicic acid (SiO2 in sol. preferably 50 wt.%) and orthophosphoric acid or a phosphate in aqueous medium (pref. free acid or acid/(NH4)2HPO4 mixture).

Patent DE-1957011-A1 (DE)
Title: Stamping tool for producing small precision - holes
Inventor: REICHEL WALTER PROF DR-ING HAB
IPC: B21D28/24
Filed: 1969-11-13
Abstract: Tool for the stamping out of small diameter precision holes in metal sheets has two concentric punches. The inner centrally disposed punch produces an initial blind pilot hole with bulges along its upper edges. After retraction the outer punch enters the workpiece material causing metal flow towards the centre where to it is free to expand. This is followed by the downward motion of the inner punch, catching up the outer punch creating a cpd. punch which finishes the hole by shearing the metal and etching the cut out piece produced. This method results in a hole which is free from distortion near its edges and cleanly cut.

Title: Disinfection of walk-through rooms, esp. operating theatres - by vapourisation of bactericide followed by ventilation and ammoniating
IPC: A61G13/00
Filed: 1973-06-20
