Title: Ingate core provided with narrow slots - is used to replace sieve plates in moulds and improve quality of castings
Inventor: HOLZMUELLER ALFRED
IPC: B22C9/08
Filed: 1976-01-22
Abstract: A core, placed in the ingate of a mould to reduce the cross-section of the ingate. The hole in the core, through which the melt flows, consits of radical slots which pass through the axis of the core. The pref. slots form a pasage shaped like a cross with arms of equal length. Alternatively, slots forming a star-shaped passge may be employed. The core is designed to replace sieve plates which are widely used in the ingates of moulds to provide a constriction, forming a dam which gives the slag a chance to separate out from the molten metal and not be carried into the mould cavity. The design avoids prior problems of turbulence and suction effects, and also the redn. in speed of the melt due to friction in the numerous holes used in a sieve plate.

Title: Sterility control in steam sterilisation in autoclave - with condenser for pressure equalisation of steam-air mixt. at end of drying
Inventor: NEISS OSKAR ING GRAD
IPC: A61L2/28
Filed: 1976-08-21
Abstract: Process for control of sterility in steam sterilisation in an autoclave is carried out without using steam in the pre-vacuum phase, with a condenser downstream. At the end of the drying phase, the steam-air mixt. remaining in the autoclave is subjected to pressure equalisation with the condenser, which is separate from the vacuum pump, and the level of the pressure increase in the condenser, or in the autoclave, is a factor for the sterility effect. The drying process is effected by closing the steam valve at the end of steam treatment and extracting the steam from autoclave and material via condenser and pump, down to a partial pressure of 40-50 mbar in the autoclave, which is a usable value with a moisture increase of approx. 1% above moisture of the porous material introduced for sterilisation.
