Patent CH-620848-A5 (CH)
Title: Tool holder for cutting tools
Inventor: BOSSHARD RUDOLF
IPC: B23B27/04
Filed: 1977-07-22
Abstract: This tool holder (1) enables a cutting body (13) to be clamped exceptionally advantageously via a bell-crank lever (3). Therefore such a tool holder is extremely suitable for deep recesses and the base (4) can be constructed so as to project to a considerable extent without this affecting the vibration tendency of the elements participating in the clamping. In addition, very good fastening of the cutting body (13) is effected by an appropriate first sloping surface (5) on the base (4) and a second sloping surface (6), guided therein, of the bell-crank lever (3). <IMAGE>

Title: Process for isolating the enzyme sulphhydryl oxidase from milk
Inventor: SWAISGOOD HARALD E
IPC: A23C9/12
Filed: 1977-10-10
Abstract: The procedure for isolating sulphhydryl oxidase from milk is as follows:     1) fresh milk is skimmed.   2) The casein is coagulated and separated off. 3) A crude, impure sulphhydryl oxidase fraction is precipitated from the whey using ammonium sulphate. 4) This fraction is equilibrated in a dilute, neutral buffer solution in order to dissociate the enzyme. 5) A first enzyme fraction is then separated off by centrifugation from protein of higher molecular weight. 6) The first enzyme fraction is concentrated to a protein concentration of 2.5 to 3.5% and then centrifuged. 7) The resulting solid enzyme fraction is once again taken up in buffer solution and freed in the same manner from constituents of lower molecular weight. 8) The enzyme, which is concentrated to 1400 to 3000 times its activity in whole milk, is isolated. 9) It can be immobilised by being adsorbed onto solid supports and can, where appropriate, be sterilised.   The immobilised enzyme can be used for eliminating the boiled taste from milk.

Granted: 1972-01-07
Abstract: An apparatus for putting a gas into contact with a liquid, especially for separating solid or liquid particles in suspension in said gas or for eliminating certain gaseous constituents, said apparatus comprising a space in the form of a diffuser adapted to effect intimate mixing of the gas and liquid by means of the formation of a turbulent and dense suspension of drops forming a kind of semi-stationary fluidized bed. The gas and liquid pass together into the bottom of the diffuser which has the form of a divergent conduit in which is created a closed circulation of liquid effecting a continuous renewal of the bed, the impurities of the gas being treated during this circulation by physical collection with or without chemical reaction, followed by a centrifugal action which separates the gas from the drops of liquid, the liquid thus recovered being wholly or partly re-cycled.
