Title: Removing harmful gases, esp from engine exhausts - by treatment with steam over cerium or germanium, opt as alloys
IPC: F02M27/02
Filed: 1975-11-15
Abstract: Discharge of harmful gases, eg. unburned hydrocarbons, CO, oxides of N and SO2 into the atmos., is prevented by treatment with steam in presence of a body contg. Ge or Ce.

The engine power and fuel consumption are improved. The amts. of CO, unburned hydrocarbons, oxides of N and SO2 discharged are nil, compared with 4-5.5% CO and 1-3% of the other gases for an untreated engine. The engine operates easily on a lean combustion mixt., in contrast to an untreated engine. Treatment is esp. over an alloy or cpd. of Ge or Ge with a metal, e.g. Fe, contg. 0.5-100 (36-40)% Ce or 45-80% Ge.

Title: Non-stick cooking utensil - has renewable inner fluorinated hydrocarbon coated thin shell and outer carbon steel shell
Inventor: RACZ NICK STEVEN
IPC: A47J36/02
Filed: 1975-11-20
Abstract: A cooking utensil e.g. saucepan or frying pan of nonstick e.g. PTFE coated type, consists of a renewable inner shell which carries a non-stick coating, and an outer shell to which the inner shell can be detachably secured in a close fitting relationship.

The utensil is easier to fabricate and more economical in the use of expensive materials. The handle can be more strongly attached. Hot spotting and burning-on of the food is less likely. Fitting of a new inner shell can be done either by the user or a service facility. The inner shell is pref. of aluminium, though glass fibre reinforced plastic may be used, and is coated with fluorinated hydrocarbon. The outer shell will normally be of ferrous metal e.g. carbon steel, or ceramic material could be used.
