Title: Diaphragm clutch mechanism
Inventor: BROQUET JEAN-MARIE
IPC: F16D13/58
Filed: 1984-01-31
Abstract: A diaphragm clutch mechanism comprises a cover (10) and a diaphragm (11) retained in position within the cover by a retaining ring (31) and lugs (26) extending between the retaining ring and the cover through openings (28) formed in the diaphragm. To satisfy the requirements involved in assembling the retaining ring on the lugs, these lugs initially have a straight end (29), whilst circumferential gaps are provided between these lugs and the retaining ring so as to define an assembly play. A zone of one of these parts (31 and 26) is then deformed three-dimensionally and clamped against the other part, so as to lock the two parts circumferentially relative to one another, thus cancelling the effect of the assembly play. <IMAGE>

Title: Pulling device for a shaft
Inventor: WILSON GRAHAM CHARLES
IPC: F16H7/04
Filed: 1986-07-01
Abstract: A pulling device for a shaft, particularly a roller blind shaft, is in the form of a housing (1) in which a cord pulley (2) is rotatably mounted, the cord pulley carrying a cord (5), arms (8, 9) of which extend out of the housing (1) through openings (7) at the bottom of the housing. The openings are symmetrically disposed on opposite sides of a vertical plane extending centrally through the housing and containing the axis of rotation of the cord pulley. The openings are mutually divergent, being directed downwardly and outwardly from said plane. If the cord pulley starts to rotate other than by pulling the cord, for example by the weight of the pulley itself, the cord which would normally be fed out of one of said openings is carried past said opening to double- back on itself and prevent further rotation of the cord pulley. A cord stop is provided to enhance the locking of the cord. <IMAGE>

Title: Central heating systems
Inventor: HANSON-GRAVILLE GEORGE
IPC: F24D3/08
Filed: 1986-10-13
Abstract: To obtain rapid heating of part of a water supply a domestic hot water cylinder C having a cold water feed inlet CW and a hot water draw-off outlet HW has positioned within the cylinder an upper indirect heating coil 2 and a lower indirect heating coil 1. Hot water feed from a boiler is passed through inlet 9 into the top end of the upper coil 2 and return water is passed back to the boiler through the outlet 8 positioned at the bottom end of the lower coil 1. The bottom end of the upper coil 2 and upper end of the bottom coil 1 are interconnected by means of an external pipe 10 and via a two-way valve 3. The other branch of the valve 3 is connected to a pipe 11 coupled with the outlet 8 through T- junction 12. The valve 3 is arranged so that when in the one position the lower coil 1 is by-passed and return flow to the boiler passes from the lowermost end of coil 2 through pipe 11 and junction 12 to the return 8. By this means heat from the boiler may be used to warm only a small portion of water within the cylinder. <IMAGE>
