Title: Microbiological Process for Recultivation of Industrial Refuse Heaps
IPC: C05F7/00
Filed: 1980-01-04
Abstract: The present invention relates to the environment protection and, more specifically, to microbiological processes for recultivation of industrial refuse heaps. The process of the present invention involves treatment of the heaps with fertilizers resulting from purification of production-communal waste waters, followed by treatment with a humic preparation containing a culture of the mold fungus Aspergillus niger. Then plowing of the ground is effected with a subsequent sowing with seeds of perennial plants. The heap surface sown with said seeds is inoculated with a bacterial preparation containing a culture of ammonifying and nitrifying bacteria. During the period of the plant sprouting and tillering inoculation is effected by means of a bacterial preparation containing a culture of azotobacter and phosphate-dissolving bacteria. All these bacteria are recovered from said refuse heaps, wherefore they are already adapted thereto. The process of the present invention is useful in the regions where it is necessary to convert refuse heaps to soil, e.g. in the regions of coal-mining and ore-mining industries.

Patent GB-2112111-A (GB)
Title: Ball valve arrangement
Inventor: WICKHAM DAVID JOHN
IPC: F16K31/126
Filed: 1982-09-07
Abstract: The arrangement employs a diaphragm 10 located between two chambers A, B, to which different pressures are applied to cause the diaphragm to move to open and close a ball valve 12. The diaphragm 10 and ball valve 12 are joined by a rod or stem 11 in contact with the diaphragm but not joined to it. If the pressure differential across the diaphragm becomes too great, the stem and diaphragm may separate thus causing unbalance because of the pressure applied to the end of the stem which is normally in contact with the diaphragm. To balance the valve in this condition, a check valve Y is provided which opens when the pressure in chamber A below diaphragm 10 reaches a predetermined high level. This high pressure is then applied via passage 17 to the underside of ball 12 thus balancing the pressure applied to the upper end of valve stem 11. <IMAGE>

The valve assembly comprises a housing (1) provided with sets of primary and secondary ports associated respectively with the two braking circuits and each consisting of a supply port (5, 6) for connection to a source of fluid under pressure and a delivery port (7, 8) for connection to a brake actuator, an exhaust (30), and two co-axial primary and secondary valves (11, 12) which are operative when actuated to isolate the delivery ports from the exhaust and connect them to the respective supply ports. The valve assembly incorporates primary and secondary pistons (9, 10) for respectively controlling operation of the primary and secondary co-axial valves disposed in the secondary piston (10), operation of the primary piston (9) being operative to control operation of the secondary piston (10), and being initiated by a pressure plate (27) for receiving a brake-actuating force and which co-operates with the primary piston (9) through resilient means (28, 29). The brake valve assembly is provided with a releasable stop (41) for limiting movement of the pressure plate (27) in a brake-applying direction until a predetermined point is reached at which the magnitude of the brake-actuating force applied to the pressure plate (27) attains a value sufficient to overcome the load in the stop, whereafter the pressure plate (27) is adapted to co- operate directly with the primary piston (9). The stop (41) comprises a fluid- pressure biassed stop member, for example a rod (42) with a head (44) acted on by pressure in-space (46) or a sleeve (61) (Figs. 2 and 3). <IMAGE>
