Title: Tensioning of wire electrodes of electrostatic dust filter - has parallel wires stretched between initially parallel frame members with tension applied to each wire balanced at other end by spring
Inventor: POITIER BERNARD
IPC: B25B25/00
Filed: 1976-06-01
Abstract: The process is for use in tensioning parallel interspaced wires (8) in a rectangular frame (6, 25, 29) and may be used to tension the wire-electrodes of an electrostatic dust filter. The parallel opposed frame members (6, 15) to which the wires are anchored are allowed to deflect during stressing and before final anchoring, thus obtd. uniform wire (8) tension. The process has three stages. First, one end (7) of each wire (8) is anchored to one frame member (6). Next the wires (8) are tensioned (F) whilst movement of the counter frame member (25) is resisted by uniformly discounter frame member (25) is resisted by uniformly distributed springs (21-14) of equivalent strength. Finally the wires (8) are individually anchored to the counter member (25). The initial anchorages may compensate for member deflection i.e. the anchorage ferrules (7) are pulled through the frame member (6) by a distance equal to the anticipated deflection at that point.

Title: Self locking nut with local deformation of thread - has controlled degree of deformation achieved by rolling external groove
IPC: F16B39/30
Filed: 1976-07-19
Abstract: The self locking nut (1) or threaded bush is made by forming an external groove (11) which deforms the thread (12) in the plane of the groove (11). The groove is formed either entirely by rolling or by first machining a groove (10) and then increasing its depth by rolling. This method of forming the groove by rolling produces a more controlled degree of thread deformation than methods which require a press. This accurate control of thread deformation eliminates the need for any further finishing operations. The nut can also be used repeatedly without loss of its locking function.

Title: Filter cloth mounting for filter presses - by fixing cloth within flat part of plate so avoiding creasing, etc.
IPC: B01D25/176
Filed: 1976-09-23
Abstract: Filter cloths are mounted in pressure filters with plates or discs. In the arrangement the cloths are fixed to the flat part of the plate so that they do nto cover the sloping part at the ends of the plates. The cloths are fitted into a semi-circular groove on the periphery of the chamber either in the flat part or at the start of the slope. A water-tight joint is made between the bearing surfaces of the plates. The cloth is fixed in such a position that it is (a) supported by the filter plate and (b) well clear of the bearing surfaces of the plates. It is not stretched by the weight of the filter cake or by the increased pressure at refilling and hence does not get damaged by pleating and getting trapped between the bearing surfaces. Because the slope is not covered by the cloth it is possible to fix to it hooks or similar implements to facilitate freeing the cake from the cloths.
