Abstract: In the known method of this type, either a continuous-action controller or a two-position controller is provided. In these methods it is difficult, particularly in the lower output range of the appliance, to achieve a good ratio between the control quality and operating frequency of the controller. The combination according to the invention of a continuous-action controller and a two-position controller having a self-tuning operating differential for controlling the supply or return temperature of hot-water heating installations is characterised by as low as possible an operating frequency and the best possible control quality in conjunction with low and high heat requirements. The preferred field of application is gas-heated flow-through water heaters for heating installations. <IMAGE>

Abstract: A method of joining the ends of papermakers fabric is disclosed wherein machine direction yarns (12) are fringed out at the fabric ends, yarn ends (16) being laid across a pinned plate (13), and yarn ends (20) being cut back so as partially to overlie the plate. Those yarns (16) which extend across the plate (13) are folded back to form loops (14) beyond the edge of the plate and a thermo­plastics matrix material (17) is applied to the plate. The matrix material (17) is made fluid by heating and, on subsequent cooling, forms an apertured end to the fabric which presents side-by-side, outwardly extending loops (14). The loops (14) at the respective fabric ends may be interdigitated to receive a pintle wire, thus to bring the fabric into endless form. 
     A variation of the method is disclosed wherein a reticulate, premoulded seam element is engaged with the pinned plate for attachment to machine direction yarns of the fabric on melting of the matrix material, the seam element including axially aligned tunnels at a free edge thereof for cooperation with similar formations at an opposed fabric end and to receive a pintle wire.

Abstract: Metal coordination complexes comprising a metal of Group 3 (except Sc), 4-10 or the lanthanide series and a delocalized Π-bonded moiety have said moiety substituted with a constrain-inducing moiety which reduces the angle at the metal between the centroid of said Π-bonded moiety and at least one remaining substituted. Preferably, the complexes comprise a cyclopentadienyl or substituted cyclopentadienyl group forming part of a ring structure in which the metal is both bonded to an adjacent convalent moiety and held in association with the (substituted) cyclopentadienyl moiety. Complexes of said preferred structure are not necessarily constrained sufficiently to reduce the said angle. Amidosilane and amidoalkanediyl compounds are particularly preferred. 
     The complexes of the invention form addition polymerization catalysts with activing cocatalysts such as Lewis acids, ammonium salts, oxidizing agents and,   especially, aluminum compounds, particularly aluminum trialkyls. 
     Novel polymers, including ElPE resins and pseudo-random copolymers, can be obtained using the catalysts of the invention.
