Title: Filter coffee maker with flavour control means - allows steam pressure and water temperature to be adjusted independently
Inventor: PATZNER HELLMUTH
IPC: A47J31/30
Filed: 1974-07-17
Abstract: When the coffee maker is switched on the water passes from the cold water inlet through the tap valve to the boiler until the water level has reached the level contact when the supply magnet valve is closed. Once the water level has reached the level contact in the boiler the heater is switched on. The steam pressure can be set on the pressure regulator and automatically kept constant since the heater is switched on when the temperature at the thermostat drops. When the actual brewing process begins when the steam pressure has been reached, a cold water valve is opened so that a mixture of cold water and boiling water is passed to the filter and ground coffee container. The brewing time can be set by a time control mechanism which acts on the boiling water valve and on the cold water valve.

Title: Fine carbon black suspended particles to protect against toxic gases - esp. for military use instead of gas masks
Inventor: BEHNCKE HERMANN DR
IPC: A62D3/00
Filed: 1974-11-07
Abstract: A method of using flame-produced soot or carbon black in suspended form consists of generating the carbon black by incomplete combustion of organic hydrocarbons contg. relatively little hydrogen in relation to the carbon content, and of using the resultant suspended product for adsorbing toxic gases. The carbon black may be generated immediately before use, directly in suspended form, by incomplete combustion of the organic hydrocarbons; or it may be generated in advance and then blown in finely divided form when required into the toxic zone. Pref. starting materials are hydrocarbons having a hydrogen:carbon ratio of less than 1:1. Used in place of gas masks, for example for military purposes. By distributing the adsorbent carbon black throughout a toxic zone contg. poisonous gaseS, it is possible for individuals to be protected, including full skin protection, without the need to wear gas masks.
