[Also in Division H2] A multi-layer super-conductor coil for providing a strong magnetic field comprises lowresistance electrical shunts across portions of the coil and means for inhibiting the inductive coupling between layers; the shunts may be provided by a continuous coating. Fig. 7 shows an embodiment in which copper shields 61-63 enclose portions of the windings of superconductor coil 64, three layers lying between each adjacent pair of shields. Each shield has switchable connections so that it can be shortcircuited or terminated by a low resistance 71 to 73. Shunt resistors 77-82 are connected across individual portions of the super-conductor coil and these act to dissipate energy which is released when the coil goes normal as described in the parent Specification. In addition, the effect of inductive coupling between these portions of the coil is reduced by shields 61-63, the effectivity of which can be varied by varying the terminal resistances. Diode rectifiers may be used in place of resistors across the shield terminal connections or in place of the shunt resistors 77-82. Alternatively mechanical switching means sensitive to current or other conditions in the coil may be used to connect a low or a high resistance selectively across the shield connections or portions of the superconducting coil.

Filed: 1976-11-24
Abstract: 1515429 Cathode-ray tubes RCA CORPORATION 24 Nov 1976 [28 Nov 1975] 49024/76 Heading H1D An evacuated cold cathode discharge tube includes a phosphor-coated anode 24 and a photocathode 18 arranged such that, with suitable voltages applied thereto, the incidence upon the photocathode of radiation from the phosphor is capable of providing sustained electron emission from the photocathode. The anode may alternatively consist of a layer of visible emitting phosphor, coated with a highly optically reflective conductive layer, in turn coated with a phosphor layer emitting radiation, not necessarily visible, to which the photocathode responds. Stray radiation, e.g. cosmic, suffices to prime the system. The flow of electrons to the anode may be modulated by space charge loading, or by capacitive coupling (Fig. 2, not shown) or resistive coupling (Fig. 3, not shown) between the cathode and a mesh grid 30. The device may incorporate an electron multiplier, the dynodes (80, Fig. 6, not shown) of which are so arranged that they do not obstruct the path between the anode and cathode. In the colour display tube of Figs. 7 and 8, which employs an addressable matrix of such cells defined by the orthogonal sets of glass vanes 96 and 98, the phosphor coated anodes 122 are formed on ridges 124 of the vanes 96, the beams thereafter entering the passages between vanes 98, where they are modulated by a video signal applied to electrodes 140, and focused and accelerated by electrodes 142 to 148 to impact phosphor stripes 150 which include alternating red, green, and blue phosphors. In a modified display tube (Figs. 4 and 5, not shown), a mesh control grid (52), in the form of strips (42) orthogonal to the phosphor stripes (45), is mounted between the two orthogonal sets of vanes (44 and 46) to permit addressing of the cells.

A cam 70 fixed to the lever shaft 64 has two recesses 74, 76 with one of which a roller 80 on a detent 78 engages when the lever is moved to actuate the piston-cylinder so that the valve member 58 is held in an end actuated position. Flow from the pump 16 to the valve 58 when actuated is via passages 20, 22, manually controlled rotary metering valve 42, passage 26, pressure-operated flow regulating valve 30 and outlet 34, 46. The pressure differential across valve 42 acts on the opposite sides of a piston 86 provided with a small diameter rod 100 acting on the detent and a large diameter rod 98 surrounded by a detent loading spring 96. While fluid flows to the valve member 58 the net fluid force on the piston is substantially zero and the spring 96 holds the detent roller 80 in recess 74 or 76. When the piston-cylinder 48 reaches the end of a stroke fluid flow ceases and the pressure equalizes on opposite sides of the piston 86 so that the net fluid force opposes the spring 96 and springs 82 can return the valve member 58 and cam 70 to neutral position, roller 80 being cammed out of its recess 74 or 76.

Abstract: 1531740 Growing plants R S FARNSWORTH 3 Dec 1975 [30 Dec 1974] 49659/75 Heading A1E Plants, such as head lettuce, are individually supported on rafts 24 floating on a nutrient solution, the rafts being closely spaced when the plants are at the seedling stage and having more widely separated as the plants grow. Initially a plurality of rafts may be joined together by a frangible membrane 26 to form a multi-unit raft 21. Each raft 24 has a hole 27 accommodating the roots of a plant; the holes may pass through the membrane or the membrane may be permeable and close off the holes, in which case a seed can be germinated resting on the membrane in a hole, and the roots pierce the membrane to grow into the nutrient solution. When the plants have grown sufficiently to touch each other, the membrane is severed between the rafts 24 and the rafts are spaced apart more widely. In one embodiment, at a first station P-1 seeds are placed on a multi-unit raft 21 which is then placed in a germination tank T-1. Once the seeds have germinated the rafts are transferred to a tank T-2, this tank being larger than tank T-1 since, although the plants do not require any more space, germination requires less time than that required for the seedling stage. A second seedling tank T-3 is preferably provided, the most mature and vigorous seedlings from tank T-2 being transferred thereto. The advantage of having two seedling tanks T-2, T-3 is that the nutrient solutions and other factors can be varied. At a station P-3 the plants are again inspected and transferred to a tank T-4 for the first substantial growth stage. At station P-3 each raft 24 may be accommodated in a recess in a larger raft having a hole accepting the roots of the plant. The auxiliary raft provides additional buoyancy and stability for the plant as its size increases. Tank T-4 is provided with a recycling trough 41. Rafts in tank T-4 are urged into trough 41 through an entry 42, at which point they are inspected. If large enough they are transferred to a tank T-5, otherwise they pass through the trough past fumigating means 46, lighting means 47 and air circulation means 48. The rafts may be moved by blades, circulating pumps, or air discharge. Tank T-5 has a recycling trough 51 having various processing stations (not shown), and a station P-5 at which the plants are inspected, and, when suitable, transferred for their final growth to a tank T-6 having a recycling trough 53. Finally the plants are inspected and harvested at a station P-6.

Abstract: 1,176,409. Automatic circuit breakers; electromagnetic switches. GENERAL ELECTRIC CO. 6 Nov., 1967 [23 Nov., 1966], No. 50248/67. Heading H1N. The contact rod 37 of an automatic circuit breaker is decoupled from an operating mechanism by current responsive means so that the contacts can move rapidly to open position independently of the operating mechanism, providing a current limiting action. An operating handle 44 is coupled to a forked lever 48 by overcentre tension springs 49. A stud 60 on a pivoted plate 58 co-operates with the forked lever 48 so that as handle 44 is moved plate 58 snaps from one position to another. A pivoted member 66 is coupled to the contact rod 37 and has pins 69, 70 projecting into a slot in plate 58. A spring 72 normally holds pin 70 in the downturned end of the slot so that member 66 moves with plate 58 to open and close the contacts as handle 44 is moved. If a heavy overcurrent occurs an electromagnet (29) (Fig. 1, not shown) draws the rod 37 rapidly to the left; spring 72 is overcome and pin 70 moves out of the end of the slot; thereafter spring 72 is effective to draw member 66 and the contacts to the left to fully separate the contacts. The contacts have a degree of overtravel such that they do not separate until pin 70 has left the end of the slot so that once they separate the contacts must move to the fully open position. If a small overcurrent occurs a bimetal strip (24) (Fig. 1, not shown) releases a latch 62 to trip the operating mechanism in the usual manner.
