Title: System for processing used waters by the biological process of activated sludge
IPC: C02F3/12
Filed: 1979-02-08
Abstract: The system comprises, besides an aeration zone and a clarification zone separated by a vertical wall (14), at least an intermediate filtering-flocculation zone limited by the vertical wall (14) and an oblique wall (12) under the clarification zone (11). Under this filtering-flocculation zone is a concentration zone (13) of the sludge limited by the vertical wall (14) and an oblique wall (10) of the basin of which the slope of 60` approximately is the same as that of the wall (12) and of about the same height. The width of the horizontal passages between the walls is such that the current of water and sludge which goes through them tends to be laminar. According to one alternative of execution the zone of concentration of the sludge does not communicate directly with the aeration zone, but through an outer conduit which brings the concentrated sludge into the aeration zone.

Patent GB-2068570-A (GB)
Title: Spring balances
IPC: G01G3/04
Filed: 1980-01-31
Abstract: A spring balance comprises a static beam 11 suspended from a hook 10 and a movable load support beam 32 suspended from the static beam 11 by two main springs 21 and 22. A tubular pressing 35 is pivotally mounted in the movable beam 32, from which it depends, and carries a load hook at its bottom. A plunger 55 comprising a telescopic stem and a head 56 within the pressing 35, supports the rack 42 of a rack and pinion load indicating arrangement. A light coil spring 63 reacts against the plunger head 56 and urges a stop ring 62 against an inwardly-directed flange 36 at the upper end of the pressing 35. The upper end of the telescopic stem is an outwardly-directed annular flange 64 which rests on the stop ring 62 but will pass into the tubular pressing 35. The light coil spring 63 yields under impulsive shock loads and thereby protects the rack 42 from them. <IMAGE>

Title: Location of high pressure gas leaks by an ultrasound technique
IPC: G01S3/803
Filed: 1980-02-04
Abstract: For locating sources of ultrasonic signals and in particular the location of high pressure gas leaks, e.g. leaks from high pressure steam pipes, an ultrasonic sound signal-receiving device has two transducers 20, 22, one having a sharply directional receiving beam and the second being fixedly mounted with respect to the first and having a much broader directional receiving beam, the two receiving beams overlapping. The signals from the two transducers are fed to logarithmic amplifiers 25, 26 and thence to a differential amplifier 27, the output of which is dependent on the ratio of the signal amplitudes and hence on the angular direction of the sound source with respect to the axis of the sharply directional beam. The device is conveniently hand-held and moved to determine the amplitude of the output of the differential amplifier, e.g. on a visual indicator 28, so as thereby to determine the direction of the sound source. Overloading in the amplifiers or indicator device is thereby overcome. <IMAGE>

Title: Improvements in or relating to agricultural machinery
Inventor: DALTON ANDREW
IPC: A01C7/20
Filed: 1982-04-14
Abstract: A drill has a pivotally mounted coulter bar (3) which carries a coulter in the form of a narrow blade (6) to cut a slit in the ground. An elongate member (10) is pivotally connected to the coulter bar (3) and a member (16) is axially slidable on the elongate member. A hydraulic arrangement (23) is provided which, by means of levers and a rota table shaft drives the member 16 downwardly thus causing two springs (14, 15) located between the slidable member and the coulter bar around the elongate member (10) to be compressed thus driving the coulter (6) into the ground. One spring (14) is relatively long and of low strength, and the other spring (15) is relatively short but of higher strength. When the drill is operated the coulter forms a swirl of tilth behind it as it is drawn through the ground. Seeds dropped into this swirl of tilth come to rest entirely surrounded by tilth and are thus under optimum conditions for successful germination. <IMAGE>
