[Also in Division G3] A tracer head for producing electrical signals representative of the deflection of a stylus with respect to three mutually perpendicular axes, comprises a mounting supported for movement about two axes and having a support for the stylus which is movable along the third axis, a transducer sensing movement about the two areas and a second transducer, within the mounting between the first transducer and the stylus, sensing movement along the third axis. A stylus 62 is retained by a screw in a tapped hole 64 in a member 42 slidably mounted within a pendulum member 36 flexurally mounted on a phosphor bronze diaphragm 30 supported by a casing 1, 2. An upper end 18 of the pendulum member extends to a screw adjusted counterweight 22 and carries a magnetic core 6 co-operating with a linear variable differential transformer assembly 8, 12, responsive to relative angular movement of the pendulum to derive X and Y axis control signals. The linear variable differential transformer assembly comprises quadrature coils such as 4a, 4b on cores, such as 4, which are adjusted to a null control signal output by grub screws 14 concealed by cap screws 16. The slidable member 42 carries a screw adjusted core 50 for a linear variable differential transformer, assembly 40 within the pendulum member 36 which has an output representative of the Z-axis movement of the stylus. The core 50 is biased into the neutral position by a spring 58 and the difference in spring constants between spring 52 and diaphragm 30 is compensated by adjusting the effective length of the spring 52 by a collar 58.

Metal articles that are to be hot galvanised or tin plated are pickled with hydrochloric acid in a bath 1, washed in a bath 2, treated with a flux e.g. NH 4 Cl or ZnCl 2 , in a bath 3, and galvanised or plated in a bath 4. Used wash water from the bath 2 passes to a tank 5 and has an ammonium hydroxide solution added to it from a tank 7 under the control of a pH meter 15. The mixture then passes to a sedimentation tank 6 where iron hydroxide separates out and is filtered off in a plant 8. The treated water is then returned to the bath 2 by a pump 22. The concentration of ammonium chloride in the recirculated water is monitored by a conductivity meter 20 and when said concentration exceeds a predetermined level a control 11 activates valves 19 and 12 so that the liquid coming from the tank 6 passes to a tank 10 and fresh water is added to the tank 21 until the said concentration falls below said level.

The tubes are connected by a manifold 3 which has an inlet 6 and check valve 7 for return service water. The inlet 12 for the first heating water, generally the return flow from a central heating system, leads to a turbulence reducing compartment 13 surmounted by a baffle 14. The inlet 16 for the second heating water, which may be the preflow of the central heating system, is provided with a valve 18 controlled by a temperature probe 19 in the service water outlet 5. A baffle 17 directs the hot heating water to the heat exchange region 2. In use, any difference in temperature between water entering through inlet 12 and water in the heat exchange region may set up convection currents so that water will pass from the space 8 to the heat exchange region through outlet 11 or at the top. If the service water is not heated sufficiently the valve 18 opens to allow hot water into the heat exchange region 2. In other embodiments, Figs. 2-4 (not shown), the space may surround the heat exchange region or be located between inner and outer heat exchange regions, or the space may be divided into two chambers by the heat exchange region.
