Title: Casting of imitation stone surfaces - by using removable mouldings forming areas for surface worked mortar
IPC: E04F13/02
Filed: 1974-08-23
Abstract: The surface to be coated is first cleaned and dressed to ensure a smooth finish. Wooden or plastic mouldings are then attached to the surface by steel nails. The mouldings can be any desired shapes which will eventually give the appearance of stonework. Once the mouldings are in place, the remaining visible areas are moistened and steel nails driven into the surface to facilitate adhesion of mortar. Mortar is then applied in several successive layers. Once the final layer has been applied and worked to give the rough appearance of stone, it is left to dry for 24 hours before removal of the mouldings. This process gives a realistic finish at a fraction of the cost of real stone.

Title: Battery powered electrically driven vehicle - has wind driven generator on vehicle roof to keep battery charged
IPC: B60L8/00
Filed: 1975-09-30
Abstract: The battery driven car (1) has a wind driven generator (3) mounted on the roof. The generator is driven by a variable pitch propeller (4) and is enclosed in a streamlined housing (6).

Title: Aq. effluent purification by microbial fermentation - feeding biomass to protozoa to form biomass as protein source
IPC: C12N1/20
Filed: 1975-12-08
Abstract: Waste waters contg. biodegradable organic materials are purified by using the waste as culture medium for microorganisms, which are maintained in the exponential growth phase. The microorganisms are those which may be ingested by protozoa and are cultured until they form a biomass which is used as culture medium for the protozoa.

Pseudomonas sp. and Brevibacterium sp. bacteria and Torula yeasts. The protozoa are pref. ciliate and are esp. Tetrahymena pyriformis and/or Colpidium camphilum. The protozoal biomass is useful as a source of protein, for human (sic) or animal feeds, and is obtd. without prodn. of an activated sludge of bacteria. The process does not lead to a loss of accumulated solar energy c. f. prior processes.
Patent FR-2336901-A1 (FR)
Title: Safety cutout for electric blanket - has two variable and two constant resistances forming Wheatstone bridge unbalanced at preset temperature
IPC: A47C21/04
Filed: 1975-12-30
Abstract: The safety cut-out automatically disconnects the supply to the electric blanket at a pre-set temperature. It comprises a Wheatstone bridge formed by two resistances (1, 2), their values increasing with temperature, and two resistances (3, 4) whose values remain constant. The supply (5, 6) is connected to two opposite terminals (7, 8) of this bridge. The remaining two terminals (9, 10) form a circuit with a negative resistance (11) and a heating resistance (12), the latter opposite a bimetal strip contact (13, 14, 15). The temperature increase causes an unbalance in the bridge, generating a secondary current and heating the bimetal strip. This strip distorts and breaks the supply to the blanket.
