Abstract: 1,171,539. Optical reflection systems. CARL ZEISS JENA VEB. Nov. 7, 1967, No.50513/67. Heading G2J. An optical system for multi-reflection of an incident beam 6 of parallel rays between two plane mirrors 3, 4 is characterized in that the mirrors respectively contain the foci of lenses 1, 2 disposed between them, the lenses being of different diameters and having parallel axes. As shown, the lenses have a common optical axis X 1  - X 1  with which the mirror 4 makes a right angle, while the mirror 3 makes an angle other than a right angle with X 1  - X 1 . The incident beam 6 strikes the part 5 of the lens 1, and is converged to the lens focus F 1  in the mirror 3, which reflects the beam back through the lens. The beam 6<SP>1</SP> now leaving the lens 1 is still parallel but of smaller diameter than the beam 6 and nearer the axis. The beam 6<SP>1</SP> passes through the lens 2 to the mirror 4 and is reflected back to form the beam 6<SP>11</SP> of equal diameter to the beam 6<SP>1</SP>. Reflection and beam contraction are repeated. The lens 2 and mirror 4 may be displaced towards the beam 6 or the mirror 4 be inclined to the axis X 1  - X 1  as is the mirror 3 to increase the contraction of the beam parallel beam passing between the lenses, which beam may be used for exciting scattered light in irradiating media. The lenses may be plano-convex with their plane surfaces conjugate and the convex surfaces Cartesian. The lenses may be cylindrical or Fresnel, or semi-lenses. Each lens and its associated mirror may form a block Fig.2 (not shown). At least one of the lenses and its associated mirror may be displaceable along the lens' axis Fig.4 (not shown). The lenses may form two walls of a specimen cell (20, Fig.3 not shown).

Abstract: 1374593 Reactor pressure vessels ELECTRICITE DE FRANCE (SERVICE NATIONAL) and COMMISSARIAT A L'ENERGIE ATOMIQUE 1 Nov 1971 [20 Nov 1970] 50626/71 Heading G6C In a method of removing the cover 12 of the prestressed concrete pressure vessel 10 of a pressurized light-water reactor, in order to gain access to the fuel elements and other reactor internals, a pool 22 which surrounds the cover 12 is progressively filled with demineralized water to a level 30 immediately below the top edge of a cofferdam 18 carried by the cover 12, whereupon the depth of water within the pool 22 ensures a satisfactory degree of biological protection and the hydrostatic forces to which the assembly of cover 12 and chamber 20 (formed by the cofferdam 18) are subjected balance the weight of the latter. An internal corbel 27 of the base slab 24 of the pool 22 is connected in leak-tight manner to the pressure vessel 10 by packing seals 28. The operations involved in removing the cover 12 are carried out in the following sequence: the reactor is shut-down and the pressure within the vessel reduced to atmospheric, tension rods 16 are slackened, packing seals 28 are placed in position, and the pool 22 is filled with demineralized water. After the cover has been released by auxiliary jacks (not shown), it is lifted by means of a gantry crane 32. Filling is continued while lifting the cover 12 in order to ensure that the water level remains close to the top edge of the cofferdam 18, and is stopped when the water reaches level 34, the cover 12 then being displaced transversely to a position above its temporary storage location. The water level is then allowed to drop as the cover 12 is lowered into the position shown in chain-dotted lines. In an alternative arrangement (Figs. 2 and 3, not shown), the cover is surrounded by an annular chamber into which air is injected via a flexible hose.

Abstract: 1291586 Jet propulsion nozzle assembly ROLLS-ROYCE Ltd 23 Oct 1969 52044/69 Heading B7G [Also in Division F1] A jet propulsion nozzle assembly comprises a housing 11 having a curved bearing surface 12 which provides a seating for a complementary surface of a swivellable nozzle member 13, seals 14 between the surfaces, a conduit 16 for supplying fluid to the surfaces, and means for applying, in operation, hydrostatic pressure to the member so as to reduce or eliminate frictional resistance to its swivelling due to thrust exerted by the propulsive jet. The pressure is applied to an annular flange 19, integral with the member 13, which divides an annular cavity 15 formed in the bearing surface 12 into two annular chambers 20 and 21, the conduit 16 supplying the fluid to the chamber 20, which is also in communication, by way of a conduit 32, with an annular groove 33 in the surface 12 so that the fluid acts as a coolant and lubricant for the bearing. The same fluid is also supplied from shuttle valve (50), Fig. 2 (not shown), to jacks 27 attached to the housing 11 which control the swivelling of the member 13.  In an alternative embodiment (Fig. 4) there are no jacks 27; the chamber 20 is divided into several sections 70 by pawls 71 mounted by ball-pivots 76 on the bearing surface of the nozzle member 13 and lying in slots in the said surface and slots 75 in the flange 19. The swivelling of the nozzle member is thus controlled by adjusting the supply of fluid to each section 70.

A process of multi-colour electro-photography comprises forming electro-photographically different colour images on transparent supports, superimposing one support upon the other, and then superimposing the combined image. Photoconductive layers 12a, 12b, 12c, which are respectively red, green and blue sensitive are carried by conductive layer 11a, 11b, 11c, cyan magenta and yellow images 13a, 13b, 13c are formed in known manner and transferred to transparent films 14a, 14b, 14c before fixing. The films are then superimposed as shown in Fig. 3. The spaces between the films may be filled with transparent resin, e.g., by coating the back of film 14c or the image 13b and film 14b within resin to cause films 14b and 14c to stack together. In another embodiment, the two image carrying films 14a, 14b, Fig.4 are superimposed on a yellow image 13c on the layer 12c. In one example (Example 2) zine oxide paper was negatively charged and then exposed through a mesh screen and red filter to a coloured original. The latent image formed was developed with cyan toner, transferred to a (Registered Trade Mark) "Mylar" film, and fixed. Similarly magenta and yellow colour separation images were produced and the three films superimposed one over another in correct registration. Developers used may be liquid developer comprising kerosene, linseed oil and phthalocyanine blue covered with copolymer of polyvinyl chloride or a powder developer comprising iron powder covered with polyvinyl chloride acetate resin and, cyan magenta or yellow toner mixed with polystyrene.
