Title: Nuclear reactors
Inventor: PERRETT ROBERT JAMES
IPC: G21C5/08
Filed: 1967-02-07
Abstract: 1,217,141. Moderator structures. ENGLISH ELECTRIC CO. Ltd. 5 Feb., 1968 [7 Feb., 1967], No. 5908/67. Heading G6C. In a nuclear reactor concrete pressure vessel, the graphite moderator block assembly is arranged in columns, has a side restraining structure surrounding the assembly and is located within the vessel by keys engaging the vessel side walls. Distortion of the pressure vessel is accompanied by a corresponding distortion of the assembly upper region, by reason of the keys, so that alignment between the standpipes and the core fuel tubes is maintained. Twisting movement of the vessel is transmitted to the core through the keys and the side restraining structure. The core is carried upon a perforated plate which is supported upon the pressure vessel floor by pillars which rock about their lower ends to permit plate radial expansion. Coolant gas is pumped through the core base upwards through the fuel stringers. Gas also passes round the moderator assembly and enters it through the upper surface before passing downwards in the interstitial spaces between the columns. A further flow occurs downwardly in the annular spaces between the fuel stringers and the fuel channel walls. The flow in the core interstitial spaces enters the fuel stringers at the lower ends. Each fuel channel contains a debris collector.

Title: Improvements in the Method and Means of using Paraffin or Crude or Heavy Oils in Internal Combustion Engines for Motor Cars, Motor Boats, Aeroplanes and other purposes.
Inventor: WILKINSON FRANCIS ALAN
IPC: F02M13/06
Filed: 1916-04-25
Abstract: 101,596. Wilkinson, F. A. April 25, 1916. Spray carburettors; vaporizers, external.-In engines using paraffin or other heavy fuels, hot exhaust gases are added to the combustible mixture before its admission to the cylinder. As shown in Fig. 1, air, which may he heated, is drawn through a pipe 3, having a cold air-inlet orifice at 4, and enters the carburettor through branch pipes 7, 8 containing controlling-valves 11, 12 actuated simultaneously by a wire 13. A throttle valve in the outlet pipe of the carburettor is controlled by an arm 9 connected to a lever 10. Exhaust gases from the outlet pipe 2 of the engine are fed to the carburettor, above the throttle valve in the outlet pipe 1, through a pipe 14 containing a controlling- valve 15. Located at the carburettor end of the pipe 14 and opening into the outlet pipe 1 is a cross-piece 19 through which air may be drawn past a suction-actuated valve or a mechanicallyoperated valve 30 to regulate the temperature and composition of the mixture. The cross-piece communicates also through a pipe 21 with a supplementary fuel chamber 22, or, alternatively, with the float chamber 5. Fuel, at starting or during normal working, may thus be drawn direct into the pipe 1 without passing through the carburettor. The fuel in the float chamber, or the chamber 22, may be heated by an electric coil or other means, the current to the heater being cut off automatically when the engine is running normally. The carburettor mav have au exhaust-heated or hotwater jacket; the air admitted through the crosspiece may be heated, and the fuel before it reaches the carburettor may be warmed in bulk or by leading it through and around the exhaust pipe. At starting, the cross-piece may be warmed by a blow-lamp. If a light fuel is used at starting, it may be supplied from a separate carburettor or from the float chamber 5. Water may be admitted to the pipe 14, and gauze screens may be located in the outlet pipe 1 above the cross-piece 19.

Title: Improvements in or relating to apparatus for displaying information represented by the instant at which a signal is received
IPC: G01S1/72
Filed: 1955-03-01
Abstract: 771,939. Echo-sounding. RAYTHEON MANUFACTURING CO. March 1, 1955 [March 24, 1954], No. 6082/55. Class 118 (2). [Also in Group XIX] Apparatus for displaying information represented by received signals, wherein a movable member (stylus 16, Fig. 1, or lamp 64, Fig. 5) which is moved in a prescribed path near a scale, co-operates with indicating means, comprises an alarm device 53 having two electric contact members, the first contact member 36 (or 77) being adapted to move, in accordance with the movement of the movable member, relative to the second contact member 26 (or 76) and to co-operate therewith to bring about the excitation of the alarm device should a signal be received while the movable member is passing a predetermined portion of the scale. The extent of this portion can be adjusted by adjusting the effective length of one of the contact members. As applied to an echo depth sounding-apparatus a contact brush 36, Fig. 1, is carried by a stylus holder 16 and after passing the zero position at which a sonic pulse is emitted the brush 36 engages a flexible contact strip 26 until it passes a block 31 which guides the strip 26 out of reach of the brush 36. If an echo is received during the engagement of the brush 36 and strip 26, an audible warning is given. The block 31 is vertically slidable for adjusting the region in which a warning is desired. The threshold level of echo signals fed from the conductor 26 which will fire a thyratron 43 is adjusted by a tap 46 movable over a potentiometer 47, the thyratron 43, a condenser 50 and resistor 49 behave as a self-quenching pulse generator and the time of travel of the stylus 15 across the paper is several times the time constant of the condenser 50 and resistor 49, whereby the bell 53 may be rung several times as the stylus moves across the paper. As applied to a flashing lamp indicator, Fig. 5, a contact brush 77 rotates with a fibre gear 59 carrying the lamp 64 and engages a flexible contact strip 76 wrapped round a portion of a cylinder 71 inside which the remainder is coiled. The length of strip 76 exposed is adjustable by turning the cylinder 59 to predetermine the range of values for which an alarm is required.

Title: Improvements in or relating to radio direction finders
IPC: G01S1/02
Filed: 1946-02-27
Abstract: 613,452. Radio direction-finding. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 27, 1946, No. 6185. Convention date, July 1, 1942. [Class 40 (vii)] A "diversity direction-finding system," to overcome the difficulties produced by the fact that aerial elements are normally " blind to some condition of polarization, comprises a number of independent arrays of aerial elements responsive to differing polarization, the arrays being selectively connected to the direction-indicating apparatus. Four vertical loops N, S, E and W are positioned in parallel planes at the corners of a square. The differential outputs from opposite pairs are fed to balanced modulators 31, 33 which are fed through a 90 degrees phase-splitter 57 from the modulation source 55. A central loop C feeds a phase-shifter 35 and the combined outputs of units 31, 33 and 35 pass to a superheterodyne receiver comprising R.F. amplifier 37, mixer 39 and local oscillator 51, I.F. amplifier 41 with automatic gain control circuit 53, detector 43 and signal shaper 45. The output from unit 45 at the frequency of the modulating oscillator is fed through a differential relay 47 to the bearing indicator 49 which is also fed with reference-phase modulation from oscillator 55. A second system of parallel loop aerials N<1>, S<1>, E<1>, W<1> and C<1> mounted concentrically with. but at an angle to the loops N, S, E, W and C are connected to a modulating and receiving channel 131, 133, 135, 137, 139, 141, 143, 145 and 153 identical with that associated with the first array of loops. The output voltages from the A.V.C. circuits 53 and 153 are fed in opposition to the differential relay 47 so that the output from the receiving channel which is picking up the larger signal is fed to the bearing indicator. The bearing indication is thus always derived from the loop system better situated to provide accurate results. The system is responsive to all waves except those which are horizontally incident and horizontally polarized and 'to preserve the symmetry of the system the leads from the loops should be brought straight down to avoid coupling to the loops. An alternative arrangement to replace each pair of loops, Fig. 3 (not shown), comprises a vertical dipole positioned coaxially with respect to a horizontal loop. This combination is sensitive to all waves except those vertically incident. A twochannel cathode-ray tube type direction finder, Fig. 1 (not shown), comprises four aerial groups, each consisting of three mutually perpendicular dipoles to form three Adcock-type systems, Diagonally opposite dipoles of like polarization are cross-connected and feed one pair of plates of a cathode-ray tube indicator. A selector switch enables the indicator to be associated with any one of the three differentlypolarized systems.
