Patent GB-2093958-A (GB)
Title: Feedwater control system
IPC: G21C19/00
Filed: 1982-02-12
Abstract: Excessive swing of the feedwater (31) in power supply apparatus on the occurrence of a transient is suppressed by injecting an anticipatory compensating signal (ΔW<sub>fw</sub>) into the control for the feedwater. Typical overshoot occurs on removal of a large part of the load, the steam flow is reduced so that the conventional control system reduces the flow of feedwater. At the same time there is a reduction of feedwater level in the steam generator (13.15) because of the collapse of the bubbles (125) under increased steam pressure. By the time the control responds to the drop in level, the apparatus has begun to stabilize so that there is overshoot. The anticipatory signal is derived from the boiling power (BP) which is a function of the nuclear power (2N) developed, the enthalpy of saturated water (h<sub>.</sub>) and the enthalpy of the feedwater injected into the steam generator (h<sub>fw</sub>). From the boiling power (BP) and the increment in steam pressure resulting from the transient an anticipatory increment of feedwater flow is derived. Thus increment is added to the other parameters controlling the feedwater.

Title: Packing biscuits, fish fingers or the like
Inventor: HADLEY MICHAEL JOHN
IPC: B65B23/14
Filed: 1982-07-12
Abstract: Articles (50) are conveyed along lanes (e.g. of a vibrating conveyor (52)) to a feed station (30) e.g. of a rotary drum collator (10) having alternate compartments (13) and abutments (16). The front rank of articles (50) are halted by an abutment (16), and so all move into line so that when a compartment (13) is presented up, they move in synchronously. The collator drum is indexed round, and a plunger 18 is displaced by a cam surface (22) to compact the articles (50) in the compartment (13), thus taking up slack space (e.g. due to lane separators 58), and tending to retain the articles (as does the guide plate (34)). At a deposition station (32) the articles (50) are ejectable into a waiting carton (48) by gravity and/or by a non-rotating pusher (72). <IMAGE>

Title: Measuring angular deviation
Inventor: GACHTER DR BERNHARD F
IPC: G01B11/26
Filed: 1985-11-07
Abstract: The angular deviation of an object is measured using an object-related target mark constructed as an optically structured screen, and using digital photoelectric evaluation of the target image. The information values obtained are compared with a reference corresponding to the target mark. The target 1, provided with a clearly defined centre 9, is imaged onto a detection plane 10 of a receiving apparatus 3. The resulting target image is scanned with the aid of a subdivided position-sensitive, photoelectric detector 5 provided with detection regions 11 within the detection plane 10. The resulting values undergo correlation comparison 6 with values derived from the stored reference and from this is calculated the deviation of the centre of the target from the optical axis. It has proved particularly advantageous to have a mark comprising constructed as a radial pattern with circular sectors of alternately light and dark regions (7, 8. fig 4), which coverage in the common centre (9, fig 4) and in which adjacent regions subtend a random angle. <IMAGE>
