Abstract: In order to produce a pulse generator, in the case of which a voltage pulse, which is independent of the magnetic field change, can be produced by sudden reversal of the magnetisation (Barkhausen effect) when a magnetic field is applied, an iron alloy 2 is used for one of the materials of the composite body, the additional alloying components of which alloy are selected such that a structural transformation takes place, with a volume change, at different temperatures in each case. In order to produce the braced state, heat treatment is then carried out, which includes heating above the upper transition temperature and cooling below the lower transition temperature. This results in considerably higher stresses between the materials of the composite body and hence a pulse behaviour which is considerably better than that known and which can be used for identifying constant or alternating magnetic fields. <IMAGE>

Abstract: A particulate fabric softening composition and a particulate fabric softening detergent composition are described, both of which include bentonite powder agglomerated into larger particulate bead or granule form with a normally solid co-melt of a penta-erythritol compound (PEC), such as pentaerythritol ditallowate (PEDT), and a nonionic surfactant, such as a condensation product of a mole of a C12-15 fatty alcohol with seven moles of ethylene oxide. The fabric softening composition described may be added to wash (or rinse water) but preferably is incorporated in a particulate built synthetic organic anionic and/or nonionic detergent composition to produce a fabric softening detergent composition. The invented detergent compositions are especially suitable for washing laundry in "cold" water, such as water at 40 DEG C. or thereabout, in which the nonionic surfactant increases the dispersibility of the PEC, improves fabric softening activity thereof, in conjunction with the bentonite, and also prevents excessive whitening or chalking of dark colored laundry by the particulate fabric softening composition. These improved results have been attributed to the nonionic surfactant lowering the co-melt's melting point to about 40 DEG C. or lower, at which temperature the softening composition disperses satisfactorily in the wash water. Additional advantages of the invention are a bonus effect of the nonionic surfactant in increasing detergency of the detergent composition and wash water, and in allowing a decrease in PEC content of the softening and detergent compositions without loss of softening effect.

It is often necessary to exchange these implements several times during a working day, necessitating the driver to connect and disconnect the hydraulic hoses involved manually, which can be a time-consuming task and one which is encumbered with the risk of oil spilling from the hoses and generally soiling the clothing of the workman involved, tools and the surrounding ground. The hydraulic hoses that hang loosely from the removed implement are easily damaged and foreign particles and contaminating particles are able to enter the unprotected and to simplify connection of hydraulic hose couplings (8, 9) to different implements having hydraulic functions when using an implement quick-coupling arrangement (1) fitted to an excavator, digger or like machine, the couplings have been positioned in a protected place in the quick-coupling arrangement (1) itself and the connection is arrangement so the when the movable part (6) of the quick-coupling moves in an implement coupling or implement uncoupling direction, the hydraulic couplings which are operative in powering movement of the implement will be connected or disconnected at the same time.
