Abstract: 1,065,272. Rotary pumps. ZAHNRADFABRIK FRIEDRICHSHAFEN A. G. July 3, 1964 [July 5, 1963], No. 27583/64. Heading F1F. A rotary pump of the outwardly-sliding vane type comprises a rotor (3), Figs. 1, 2, 3 and 5 (not shown), attached to a driving shaft (2) by splines (74) and carrying a plurality of radial vanes (5) in slots (4), which vanes engage with a substantially elliptic bore in an abutment or cam ring (6) lodged in a casing 1 between circular pressure-loaded check-plates (7, 8) having limited freedom to move axially in said casing and fluid-inlet ports (42, 42') communicating with an inlet passage (21') through an annular chamber (21) surrounding the cam ring, chambers (17, 18) at the rear of the check plates being connected to each other by pairs of fluid-outlet ports or apertures (45, 46) in said plates and a pair of axial bores (49) in the cam ring whilst the chamber (17) is connected to an outlet (17') for pumped fluid by a passage (77) in said casing. A surface (14) on the rear of the plate (8) has a greater area than that of an annular surface (13) on the rear of the plate (7) whereby pressure exerted by fluid in the chambers (17, 18) effects a resultant axial-thrust causing the plate (7) to be pressed against a shoulder (32) on the casing with consequent sealing of the ends of the cam ring and the rotor in accordance with the output pressure of the pump. The vanes are pressed against the cam ring by fluid entering the slots (4) through axial bores (52) in the plate (8), which bores are in register with arcuate ports (53) in the plates (7, 8). Initial loading of the plate (8) is provided by compression springs (20), Fig.4 (not shown). Pressure in a space (60) between the innermost end of the shaft (2) and the plate (8) is relieved through bores (67, 68) in said shaft and a bore (66) in the plate (7) communicating with one of the ports (42, 42') within this plate.

Title: Plastics material mesh structure
Inventor: MERCER FRANK BRIAN
IPC: B29D28/00
Filed: 1982-10-05
Abstract: In order to provide uniaxially-stretched and biaxially-stretched mesh structures which allow for different specific designs of the interconnecting strands, a special punching pattern is used to provide holes 2, 3 in the starting material 1. The starting material 1 has a "square" pattern of large holes 2. Further holes are added. These further holes can be small holes 3 which are staggered and in pairs. When the starting material is stretched, the uniaxially-stretched structure has transverse bars 9 interconnected by highly orientated strands 6 each of which forks at both ends into further highly orientated strands 8, providing a structure which is particularly suitable for soil reinforcement. When the structure is stretched in the direction at right angles to form a biaxially-stretched structure, the zones of the bars 9 which are between aligned strands 8 remain as unorientated or partly orientated junctions 19. The remaining zones of the bars 9 are stretched out to form highly orientated strands 15, 17. This biaxially-stretched structure is particularly suitable for soil stabilization.

Title: System to clear particles from outlet in activated sludge process
Inventor: FELDKIRCHNER HEINZ
IPC: C02F3/08
Filed: 1985-05-02
Abstract: In an activated sludge process for the purification of wastewater, in a completely mixed tank in the presence of carrier particles for the microorganisms, the aerating gas feed creates a tubular spiral circulating flow of the wastewater about a horizontal axis extending from the inlet zone to the outlet zone of the tank. To avoid a buildup of the carrier particles in the outlet zone of the tank, the gas feed maintaining the circulating motion is reduced along the axis of flow with respect to the gas feed set in the initial zone of the flow path. Gas may also be sparged along an axis transverse to the flow near the outlet to create a tubular flow which also clears the carrier particles from the outlet.
