Title: Grabheads for nuclear reactors
Inventor: DEACON DAVID
IPC: G21C19/10
Filed: 1965-11-19
Abstract: 1,147,794. Grabs for lifting nuclear fuel elements. ENGLISH ELECTRIC CO. Ltd. 18 Nov., 1966 [19 Nov., 1965], No. 49238/65. Heading B8H. A grabhead for use in nuclear reactors has jaws 16 which are opened by a plunger 21 which is depressed by a rod 23 when a solenoid 30, of similar construction to that described in Specification 1,056,412, is energized. When the solenoid is de-energized a spring 22 raises the plunger 21 and the jaws are closed. Projections 18, 19 on the jaws engage cam faces on the plunger 21. If an arm 50A of an emergency lever 50 is pushed inwards a forked arm 50B depresses the plunger 21 and opens the jaws. A supply cable for the solenoid runs through a lifting rope 40 which may be of the kind described in Specification 1,081,487. The position of the solenoid may be deduced by measuring the iron loss therein. This can be done by applying an A.C. voltage to the solenoid and measuring the current. Radial fins 13D align the grabhead within the fuel channels of a nuclear reactor.

Abstract: 1482679 Coffee filter INTERELECTRIC AG 25 Nov 1974 [28 Nov 1973] 50928/74 Heading A4E [Also in Division B1] A reusable coffee-filter comprises a water container 1, a sieve sheet 4 in the bottom of the container, a water distribution cover 10 supported by the container and provided with a central water passage portion 11, having a smaller area than the surface area of the sieve sheet, and a separating ring 8 which is fixed in fluid-tight manner to the upper side of the sieve sheet, thus dividing the sieve sheet into an inner and an outer portion, and which is contoured and arranged such that the inner portion of the sieve sheet receives all water flowing through the water passage portion of the water distribution cover. The cross-sectional area of the separating ring is approximately equal to or less than that of the water passage portion of the distribution cover. The separating ring is welded to the sieve sheet and is connected to the water container by bars. The separating ring, bars and water container may be moulded integrally from plastics material. A tapered portion may be fixed to the lower portion of the bottom of the water container. The sieve sheet may be provided with a reinforcing edge 5. The device is suitable for a range of quantity of coffee powder used in ring 8 since water from 11  runs through a small quantity of powder in ring 8 thus using only the central portion of the sieve sheet, but larger quantities of coffee powder will cause the flow to be restricted and water and coffee from ring 8 will overflow into the outer portion of the sieve sheet thus using the whole of the sieve sheet.

The strands extruded from an outer row of apertures A, are of higher density than strands extruded from at least an adjacent inner row of apertures B which, for 10 to 80% of their lengths at their downstream ends, are of an enlarged crosssectional area which is of 1À1 to 3À6 times that of the apertures A, to suppress foaming of the strands from the apertures B and their appearance as lighter coloured streaks at the board surface. In the Figs. 1 and 2 embodiment, the adjacent inner row of apertures B or the adjacent inner rows of apertures B and C, are of the enlarged cross-sectional area, with the remaining inner rows of apertures D being of the same, or of larger or smaller area, than the outer rows of apertures A. In the Fig. 3 and 4 die (not shown), the apertures are arranged to define a "U" section moulding. In the Fig. 5 embodiment (not shown), only the adjacent inner row of apertures along two opposed sides are of enlarged section, and the remaining apertures (C and D) are arranged in staggered relationship similarly to Figs. 1-4, but with only half the number of apertures per row as in Fig. 7, where the apertures A are of 1-1 to 1À7 times the diameter of apertures C and D.

In a double-beam photometer Fig. 1 for directing beams of light 15, 16 through a sample cuvette 19 and a reference cuvette 20 to a photo-multiplier 21, a magnetic stirrer 24 in the sample cuvette 19 is magnetically coupled to a first drive magnet (not shown) rotatable on a vertical shaft beneath the cuvette. To minimize disturbances in the photo-multiplier current due to stray pulsating magnetic fields, a compensating stirrer 24 in the reference cuvette 20 is coupled to a second drive magnet (not shown) geared to the first drive magnet so as to cause the stirrers24 to rotate in opposite senses with their respective opposite poles successively becoming adjacent, Fig. 7. Asymmetrical arrangements are possible, wherein the two magnetic devices are of different strengths and positioned differently relative to the photo-multiplier, preferably with the two drive magnets rotating synchronously in opposite senses. The method may also be performed by sensing the magnetic disturbance due to a single magnetically-driven stirrer and generating a compensating signal.
