Abstract: Workpieces to be heat treated (for example to be annealed or sintered) are passed through a continuous furnace having in sequence, an entrance, a thermal treatment region, a cooling region and an exit. Ingress of air into the furnace through the entrance and exit is prevented. Typically the cooling region is provided at its exit end with one or more curtains or partitions providing a physical obstruction to the flow of air into the furnace and a flow of non-reactive gas (eg nitrogen) also to inhibit ingress of air. The curtains or partitions may form one or more chambers with the furnace and the nitrogen supplied to such chamber or chambers. Non-reactive gas and reducing gas (eg hydrogen) are introduced into the furnace to provide substantially non-oxidising conditions therein. The flow regimen is such that atmosphere or different compositions are created in the thermal treatment and cooling regions. By severely limiting ingress of air into the furnace and creating eg differential hydrogen concentrations along the furnace overall consumptions of gas may be considerably reduced.

Abstract: A flowmeter has a tank disposed between a discharge circuit and a supply circuit from which the tank is refilled when the level of the liquid in the tank falls below a predetermined level. A plunger is suspended in the tank by a force sensor. The output of the force sensor is used to measure the rate of flow from the tank to the discharge circuit except when the tank is being refilled. Flow from the tank during a refilling cycle is approximately measured in response to flow parameters in the discharge circuit which are independent of the force sensor and liquid level in the tank. The flow parameters in the discharge circuit are monitored and calibrated during each tank discharge cycle, and the new calibration values are used during the next tank refilling cycle, to obtain reasonably accurate continued flow measurement during each tank refilling cycle.

Abstract: Type A, especially type 4A zeolites are well adapted as detergent builders, said zeolites comprising (i) primary particles having a mean particle diameter ranging from 0.1 to 10 mu , (ii) a cation exchange capacity in excess of about 100 mg CaCO3/g of anhydrous material, and (iii) a rate constant, relative to the surface area of the zeolite per liter of wash solution, in excess of about 0.15 s-1 lm-2. The builders are prepared by first determining the value of the rate constant for a given zeolite sample. Since a higher rate constant value corresponds to a lower degree of salt incrustation on fabrics, only those zeolites having a value above the predetermined minimum will be incorporated into detergents. Thus, zeolites otherwise appearing identical can be differentiated, with only those not causing high levels of incrustation being selected.
