Title: Sewage purificn. plant for small communities - operating by extended aeration with glass wool mat to improve oxidn.
IPC: C02F3/12
Filed: 1976-04-05
Abstract: Sewage purificn. plant for small communities, based on the "total oxidn." or extended aeration process, comprises a conical tank, a cone section deliminting a decantation zone towards the outside and an oxidn. zone towards the inside, and a thick layer of glass wool on the cone. This breaks up the air bubbles introduced at the base of the oxidn. zone from a compressor, and also retains the activated sludge recirculated through the slits. The water to be purified is introduced at the base of the oxidn. zone and passes through the opening to the decantation zone; this is divided into four cells by partitions with holes located alternately at the top and the bottom. Heavy matter separates out and is recirculated through the slits; they rise towards the last opening in the upper part of the plant and bring any "bulked" sludge, which is lighter than water, to the surface. Preferential circulation of the fluid in the decantation zone improves the retention time. The oxidn. yield is good and the final effluent is free from suspended solids.

Title: Electronic ploughing depth control system - incorporates speed sensors transmitting signals to circuits connected by two valves (NL 26.4.77)
IPC: A01B63/111
Filed: 1976-10-22
Abstract: Unit has two speed sensors (A,B) an electronic circuit (CE) and a control circuit (CC). The outlets (U1, U2) of the circuit (CC) are connected to two electrically controlled valves (EV1, EV2) which raise or lower the plough share by means of an auxiliary hydraulic system. On sensor (A) gives a signal corresponding to the tractor's speed to the input (E1) of circuit (CE). The other sensor (B) gives a signal corresponding to the rotational speed of the tractor wheels to the input (E2) of circuit (CE). The circuit (CE) calculates a figure based on these signals which is compared with a pre-set ploughing depth figure. Unit has an additional circuit (RL) which is inserted between the outlet (U) of circuit (CE) and the input (E) of step (CC). The unit (P) of circuit (RL) has the output signal of a threshold circuit (CS). Another input (Q) has a sensor or switch (1). The circuit (CS) transmits a signal for raising the plough only if the ploughing depth reaches and exceeds the pre-set figure, which is fed in as the DP signal.
Patent FR-2359686-A1 (FR)
Inventor: TAGLIABUE GIUSEPPE
IPC: A01D34/82
Filed: 1976-11-10
Abstract: The problem solved by the handle is that of preventing the user from steering the lawnmower if the handle is tilted so that the distance between the rotary blade and the vertical passing through the handle is less than a minimum safety distance. For this purpose the tiltable handle for a lawnmower has a part in the shape of a stirrup, the arms (10, 11) of which are elastically approachable and provided at their ends with toothed components (12, 13) which can engage with complementary fixed toothed components (6, 7). An eccentric lever (14) acts on one of these ends and is connected to a tie rod (8) which acts on the other of these ends. The toothed components and complementary components (6, 7; 12, 13) have projections which are designed to overlap and thus prevent the teeth from engaging at a given inclination of the handle (1).

Title: Automatic brake lining wear adjuster - uses inclined washer on piston rod to limit return travel of piston
IPC: F16D65/54
Filed: 1977-06-07
Abstract: The brake cylinder (1) houses a piston (2) which is acted on by fluid pressure supplied through the inlet (3). A washer (7) with a small clearance (7a) fits over the piston rod (6). The movement of the washer (7) is restricted partly over the piston rod (6). The movement of the washer (7) is restricted partly by the head (13) of the screw (12) which screws into the cylinder end cover (5) and partly by the spring loaded rod (10). When the brake is applied the washer (7) moves with the rod (6) for the distance (X) when the washer abuts (7) against the end cover (5). Any further piston travel tilts the washer so that it is perpendicular to the axis of the rod (6). The grip on the rod is released and the rod can pass through the washer.
