Abstract: 1,203,507. Linear motors. MERLIN GERIN. 30 Aug., 1968 [1 Sept., 1967], No. 41587/68. Heading H2A. A linear induction motor comprises a body guided for movement along a linear path defined by a fixed electrical conductor connectable to an A.C. supply, the body including an annular magnetic core member carrying a first winding and disposed around the conductor so that in use current is induced in the first winding by the electrical conductor, this current is then fed to a second winding disposed on the body and adapted to produce a travelling magnetic field to move the body along the path. As shown, a magnetic armature 26 is surrounded by a tubular conductor 60 which induces current in a winding 30 mounted on an annular magnetic core 28. The induced currents are fed to a second winding located in circumferential slots 32 in the core 28. The coils are either all connected in series with some of them associated with shading coils 38, Fig. 4 (not shown) to produce a travelling field or, alternatively, two parallel connected partwindings are formed having coils in alternate slots, one part having a series-connected phaseshifting capacitor. In a modification for threephase operation, Figs. 6, 7 and 8 (all not shown) three armatures are provided each carrying a tubular conductor connectable to a respective phase of the supply and each surrounded by an annular core carrying a first winding, these first windings together supplying three phase currents to a three-phase winding on one or more of the cores, whereby the cores, which move together as a unit, are caused to move. In a further modification, Fig. 1 (not shown), a conductor (10) is surrounded by an annular core (12) having an air gap through which a support (16) for the conductor extends, current induced in a winding (18) on the core being passed to two windings (20, 20<SP>1</SP>, one in series with a capacitor) placed adjacent a conductive part 22 of the support to produce the movement.

In producing a parallax panoramagram, use is made of a continuous web of plastics material 82 having elongated parallel lenticles 88 on one face and on the other a layer of micro-encapsulated adhesive means. These may be micron-sized capsules 90 containing an adhesive solvent such as toluene or methyl ethyl ketone, which is liberated when the capsules are ruptured by pressure. The web is fed from a roll 80 and over a guide roller 92, where it comes together with a picture 102 delivered from feed rollers 98, 100. The picture 102 consists of a series of linear picture elements which has been made by the method and apparatus of Specification 1, 269, 971 and it is laid in contact with web 82 so that the picture elements are parallel to the lenticles 88, to which they correspond in width. An indicator line 110 is provided along one edge of the picture, and this is sensed by a pair of photo-cells 112, 114 which check that lenticles and picture elements remain parallel. Web 82 and picture 102 now pass in contact between pressure rollers 116, 118, which rupture the capsules to release the bonding material. After passing through an oven 128, the web is severed by a cutter 134 and delivered to a chute 138.

The tube 20 has a perforated conical portion 34 within the bore 38 and terminates in a cylindrical portion 42 whose end is closed and whose side wall is formed with apertures 44. The cylindrical portion 42 penetrates into the passage 30 for enough to collect liquid coolant coming only from the fuel assembly 12 immediately below it and this passes up into the conical portion 34. The conical portion 34 and the bore 38 bound a gas inlet chamber 40 into which gas from a tube 16 discharges. The gas is at a pressure slightly higher than that of the liquid coolant at the fuel assembly outlet, and passes through the perforated conical portion 34 to form a dispersion in the liquid coolant. The dispersion rises up the tube 20 into a tank 18, the level of which above the free surface 22 of the liquid coolant is such that a separation occurs between the liquid coolant, which returns to the reactor core, and the gas, which is removed by a pump through a conduit 50.

A method of making a field effect device includes the steps of diffusing impurity into a surface area of an N(P) type silicon wafer part of which is partially masked by a thin layer of silica, to form a P(N) sub-surface region which is thinner beneath the silica layer. A plurality of such devices is made from a P-type wafer by first heating in wet oxygen to form an oxide layer which is then selectively removed by photo-engraving techniques to expose the silicon through a plurality of windows. After forming a central thinner strip of silica across each window, as above, phosphorus is diffused in to form N-type layers which are thinner beneath the strips. Each device configuration is then provided by evaporation of gold or aluminium with strip form electrodes consisting of source 7 and drain 8 (Fig. 2) on the N-type layer 5 and gates 6 on the silica strip 4, and 13 on the back face of the wafer. In an alternative form (Fig. 3, not shown) the central strips are replaced by strips of zigzag form and the source and drain electrodes are comb-shaped.
