Abstract: Filter for lubricants of internal combustion engines particularly for motor vehicles, of the screwed-on type, both for total continuous (full-flow) filtering and double (bypass) filtering, the latter being obtained by superimposed filter cartridges (3, 4) with separation of the flow of filtered lubricant. The characteristics of the filter is that it comprises an incorporated reservoir (8, 108) for the reserve additives adapted to be admitted to the lubricant at an appropriate moment to reintegrate the original additives which are degraded or exhausted after a certain period of operation. The reservoir (8; 108) communicates with the rest of the filter through a discharge conduit (2; 121), normally closed by an on-off piston valve (32;132) actuatable by means of an outer knob (35; 135), and through a feed hole (24; 124) normally closed by a check valve (25; 125). When the on-off valve is opened - with the engine idling - the check valve is opened, too, and the reservoir of the additives is brought into communication with the rest of the filter, thus obtaining mixing of the additives with the lubricant which is fed directly to the oil sump.

Abstract: To save energy in the production of steel in an electric arc furnace while increasing the total input of energy, the employment of carbonaceous fuels and oxygen-containing gases is proposed. The oxygen or the oxygen-containing gases are led into the furnace in the upper part of the furnace through stationary top blow-in devices (4) into the space between the pitch circle of the electrodes (10) and the furnace wall (3). The resulting intense gas flow repeatedly sucks in the reaction gases arising from the scrap or the melt being formed and burns them. The heat thus set free is transferred to the scrap and/or the melt with a thermal efficiency of at least 70%. By nozzles (2) arranged below the surface of the bath, and preferably in the furnace floor, preferably oxidizing gases are led into the melt and solid materials, particularly carbonaceous fuels, are supplied to the melt through one or more hollow electrodes (6) with an abrasion-resistant cladding. With this process, increased energy input into the electric arc furnace becomes possible, and thus the melting down time can be shortened and the economy of the process improved.

Date Jan. 28, 1988.It is foreseen to measure the rotational speed (V) of a motor (4) by measuring the electromotive force (e.m.f.) This e.m.f. is calculated as the difference between the terminal voltage (Va) and the voltage drop at a reference resistor (S), through which the armature current flows, then this value is used as a velocity feedback signal for motor regulation. Particularly, the terminal voltage (Va) is cyclically measured at two successive close instants (t1, t2), during which the armature resistance (Ri) and the motor e.m.f. can be considered constant; these terminal voltage values (Vat1, Vat2) are stored, then elaborated to perform the actual armature resistance (Ri) during that interval (t1-t2), then this value is multiplied for the instant current (I). The result is then substracted from the terminal voltage (Va) and only at that time the resulting e.m.f. is used as a velocity feedback signal for the velocity feedback circuit. The apparatus for carrying out this process is also disclosed.
