Title: Deaerator level control
IPC: B01D19/00
Filed: 1981-09-01
Abstract: In a power plant 11, a deaerator 39 is a feedwater conditioning device which provides direct contact feedwater heating as well as providing for oxygen removal to inhibit corrosion. Under some conditions, called transients, rapid depressurization could occur in the deaerator 39 which might result in damage to internal deaerator parts. A valve 33 is effective to the condensate flow into the deaerator 39, whereby the rate of depressurization can be reduced. A control system 61 is described which will react to a reduction in turbine load by reducing the flow of condensate to the deaerator 39. <IMAGE>

Title: Concrete Workability Meter
IPC: G01N11/14
Filed: 1982-01-21
Abstract: Concrete workability is measured by immersing paddle 10 into the concrete and actuating switch 17 so that battery 13 supplies current to meter 14 and hence torque to paddle 10. A meter 16 measures the current supplied by battery 13 to rotate paddle 10 and a measure of workability is read off visual display 18. In a modification, a potentiometer is included in the circuit, current is gradually supplied to the motor so that torque to the paddle 10 is gradually increased and a reading from visual display 18 is taken when movement of paddle 10 is just initiated. In another embodiment (Figs. 2 and 3) torque is supplied to the paddle by a manually rotatable member by way of a spring. Workability is measured by measuring the increase in tension of the spring to initiate paddle rotation. <IMAGE>

Patent GB-2095438-A (GB)
Title: Timepiece having an auxiliary indicating member for supplementary data
IPC: G04B13/02
Filed: 1982-03-24
Abstract: When a timepiece stem 2 is pulled out (to the left in Figure 2), a rocking lever mechanism 4,7 moves a sliding pinion 3 inwards from a rest position O to a first working position I and then to a second working position II. The pull that has to be applied to the stem 2 in order to effect the movement from the first working position I to the second working position II corresponds to only a part of the pull required for the complete resetting of the spring of the rocking lever mechanism. In the position I, a toothing 36 on the sliding pinion meshes directly with a toothing 13 which projects from the underside 16 of a date ring 1. In position II, the pinion 3 moves fully inward so that its crown toothing 3a meshes with a gear 14 for hand setting. The rest (or winding) position O and the second working position II are thus located one on each side of the first working position I. The set of teeth 13 on the ring is located approximately midway between the edges of the said lateral surface 1b, which makes possible a more compact construction of the timepiece, and are shaped to avoid jamming as the pinion 3 is displaced. <IMAGE>
