Title: Carpet sweeper with self-cleaning rotary brushes - includes cleaning comb with tooth gaps related to tooth widths
IPC: A47L11/33
Filed: 1973-07-19
Abstract: The carpet sweeper has a cleaning comb which strips the dirt and dust from the rotating brushes and the width of the gap between each tooth of the comb is a multiple of the width of an individual tooth. At the bottom of each gap is a small projection whose point slides along the peripheral surface of the rotating brush and when the tips of the teeth engage deep in the rotating brushes the bottom of the gap just touches the peripheral surface of same. The small projections thus clean the surface dirt of the brushes whilst the teeth penetrate down to remove the remaining dirt and dust. The resistance between the rotating brush and cleaning comb is slight so that the mobility of the carpet sweeper is not impaired.

Title: Hydrocarbon-water fuel mixtures - containing sulphonated products and opt metal or metalloid powder
IPC: C10L1/24
Filed: 1974-08-26
Abstract: System for mixing hydrocarbons, particularly gas oil or light or heavy fuel oil, with pure or oxygenated water, in which the products used to produce these mixtures are sulphonated products, detergents, surfactants and wetting agents and fatty material, optionally sulphonated, in proportions varying according to the characteristics of the hydrocarbons and of their components and additives. In particular, fuels so produced do not require modifications to be made to the feed circuits or boilers, burners, reactors or engines. Reduces environmental pollution by permitting the incorporation of used oils into the mixtures. Very substantial quantities of water can be introduced into the mixture, in certain cases exceeding the quantity of hydrocarbon, so that this characteristic can be used in fire fighting with possible recovery of the hydrocarbon. The water may advantageously be oxygenated and the product if dense enough has a 'gel' structure in which metal or metalloid powders can be incorporated. Incendiary weapons can be produced by the use of suitable powders e.g. P, Mg etc.
