Title: Improvements relating to visual indicators
Inventor: EBEL FRANCIS LEONARD
IPC: B64D43/00
Filed: 1953-07-23
Abstract: 759,858. Visible signalling apparatus; electric two-position indicators. FAIREY AVIATION CO., Ltd. July 23, 1954 [July 23, 1953], No. 20516/53. Classes 40(1) and 118(2) [Also in Group XXXIII] A multiple visual indicator comprises at least two units each including an armature acted on by an electromagnet against the action of a spring such that the electromagnet when energized will hold its armature in an operated position when it is' moved thereto but will not move it into said operated position, and a manuallyoperable member arranged to move the armatures simultaneously to their operated positions and then release them, and means associated with each armature which gives a visible indication if the armature remains in its operated position. A translucent sheet 10 internally edge-illuminated by lamps 27 has indication areas 24, each defined by an annular groove in which a cup-like opaque shutter 29 is normally located. The face is rendered opaque apart from the areas 24 such that light from the lamps 27 cannot be seen unless a shutter 29 is withdrawn.. Each shutter 29 is attached to an armature 53 associated with a respective electromagnet 14 but spring- urged away therefrom so that the shutter 29 is normally in the position shown in Fig. 3. When energized, the electromagnets 14 are not capable of moving their armatures, but will hold them if they are placed in the operated position. A push-button assembly 12 is arranged centrally to move all the armatures 53 'to their operated positions when it is depressed. Each electromagnet 14 is connected to respective relay contacts 15 (Fig. 2) which are closed in response to a condition requiring an indication, e.g., failure of a service in an aircraft or completion of an operation such as lowering the undercarriage. The relay contacts are also connected via contacts 60, 61 to a lamp 13 accommodated behind a glass 33 in the push-button assembly 12 in series with a flasher 16. The contacts 60, 61 are opened when the associated armature 53 is in the operated position. Thus when any particular relay contacts 15 are closed the lamp 13 flashes and attracts the attention of the pilot. The pilot first rotates the assembly 12 about its own axis to cause a metal strip 49 to bridge two contacts 46 (only one of which is shown) and light lamps 27, and then pushes it inwards. All the armatures 53 are thereby moved to their operated positions and shutters 29 withdrawn to light up all the windows 24. On release of the assembly 12 all the shutters 29 except that associated with the energized electromagnet 14 are restored and thus only the appropriate window 24 remains illuminated. The windows 24 may be engraved to indicate the functions supervised. Specification 759,896 is referred to.

Title: Protection circuit for cathode ray tubes
Inventor: ALLANSON DOUGLAS
IPC: H04N3/20
Filed: 1960-06-14
Abstract: 930,734. Cathode-ray tube protection circuits. PYE Ltd. June 8, 1961 [June 14, 1960], No. 20842/60. Class 40 (7).  In the absence of one or more magnetic scanning fields the beam of a C.R.T. is cut-off, the fields being sensed by search coils or magneto-resistive or magneto-voltaic elements. During normal operation, the signals induced in search coils L1, L2 and L3, L4 by the horizontal and vertical scanning fields respectively are rectified at X1, X2 and applied respectively to overcome the negative biases applied to the suppressor and control grids of pentode V1 by potentiometers P2, P1, respectively. The pentode is thus conducting and relay RL operated to maintain the C.R.T. beam. If either scanning field fails, the associated grid of valve V1 becomes negative, the valve cuts-off, and relay RL is de-energized to switch-off the beam. In this embodiment the inductance L5 is provided to cause ringing in the circuit feeding XI and transformer T1 is so designed as to cause ringing in the other input circuit so that the circuit may function on both forward and reverse directions of scan. In another embodiment the pentode is replaced by a pair of series-connected triodes and the horizontal search-coil output is fed to a pair of diodes, one of which acts as a D.C. restorer, so that the arrangement can accept positive and negative pulses.

Filed: 1959-06-18
Abstract: 900,055. Reactors. DOW CHEMICAL CO. June 18, 1959, No. 21016/59. Class 39 (4). In a neutron amplifier or multiplier a number of convergent nuclear reactors are mounted together in a series of stages so as to produce a neutron flux which increases from stage to stage, each stage exciting the succeeding one. In the present invention, feedback of epithermol neutrons (i.e. high energy neutrons) is reduced and the impedance to the passage of neutrons in the required direction is reduced. As shown, Fig. 1, in the fuel zone 14<SP>11</SP> of stage 3, a thin layer, 14A, of U235 is placed to the left of the thermal neutron cadmium barrier 15<SP>11</SP> and converts thermal neutrons which would otherwise be absorbed by the cadmium, into fast neutrons which pass into the next stage. To increase the transparency of the fuel zone to epithermol neutrons moving towards stage 4, cavities 14C are formed in the fuel 14<SP>11</SP> by stainless steel or aluminium cores. To prevent the absorption of thermal neutrons of the moderator layer 13<SP>11</SP> by the cadmium barrier 15<SP>1</SP> of stage 2, the light water, thermal neutron scattering layer 13<SP>11</SP>A is imposed between the moderator and 15<SP>1</SP>.

An endless conveyer belt is supported on the surface of water by being formed with an air cushion between outer and inner belt portions 12, 11. The cushion may be in the form of a number of separately-inflatable, longitudinallyextending, side-by-side chambers (15) (Fig. 2, not shown). The upper and lower runs of the belt may be spaced apart at intervals by support rollers 38. These reduce the friction between the belt runs and may also increase their buoyancy by being air-tight or by carrying cork or pneumatic floats (59) (Fig. 8, not shown). The rollers 38 are connected on each side of the belt by a respective cable 37 which may also carry floats. The driving and return roller 5 of the conveyer is mounted on a turntable 33 carried by a fixed frame 31. Guide rollers 54 for the belt are carried by arms 50, which are supported at respective ends by a float 53, and a pivotal connection to the turntable 33. The belt may have sidewalls which may be corrugated (Fig. 2, not shown), or inflated (Fig. 3, not shown), or may be in the form of individual short members (25) of plastics coated polystyrene. The belt may have chevron shaped projections on its inner face (Figs. 4, 4a, not shown) in order to reduce friction. In the form shown in Figs. 9, and 9B, inflated balls 68 are supported in apertures formed in cross members 67 of a chain assembly 63. The upper run 74A of the belt is supported troughwise by the balls 68, and the lower run 74B is supported on rollers 72 supported beneath the chain. Floats (not shown) are secured to longitudinal members 63 of the chain.
