Abstract: 1489378 Pre-combustion chamber engine carburetters HONDA GIKEN KOGYO KK 14 Oct 1974 [15 Oct 1973] 44453/74 Headings F1B and F1H The air-flow velocity in a constriction 21 of an auxiliary carburetter 15 approaches sonic, e.g. 280 m/s, at idling of the engine and remains substantially constant over a substantial part of the operating range of the engine above idling. The minimum flow cross-section of the constriction 21 is smaller than that of the flame passage 5 between the engine pre-combustion and main combustion chambers 6 and 4. The carburetter 15 supplies a richer mixture to the pre-combustion chamber 6 than the main carburetter 6 supplies to the main combustion chamber 4 and the carburetter 15 may supply a still richer mixture above a predetermined engine speed with the main throttle valve 43 in the idling position by the provision of an air bleed 29 which is open only when throttle position and engine speed switches 35 and 36 are closed. The carburetter 16 may supply a richer mixture when the suction in the carburetter 15 downstream of the constriction 21 and acting on a diaphragm 58 is insufficient to prevent opening of a valve 56 in an additional fuel flow-path to the main carburetter nozzle 41. The air-fuel ratio of the carburetter 15 may be changed by a valve controlling fuel flow in the passage 24.

Abstract: 1,116,811. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 22 Oct., 1965 [30 Oct., 1964], No. 44458/64. Heading G6C. A spacer grid for a cluster-type fuel element comprises a plurality of identical cells 2 of octagonal shape fabricated from strip material, alternate sides 3 of each cell 2 being secured to registering sides of adjacent cells so as to build up a complete cell structure, the outer sides of the outer cells of this structure being secured to a surrounding strip 9, and those sides 3 of each cell 2 which are not secured to registering sides of adjacent cells or to the strip 9 having inward projections 8, e.g. dimples or stampedout tongues, for contacting and locating a cylindrical fuel rod. The securing together of registering sides of adjacent cells and of sides of outer cells to the strip 9 can be effected by spot welding or by brazing. The strip 9 is provided with outward projections 10, e.g. dimples or stamped-out tongues, for locating the grid in a casing 11 forming part of the fuel element. Several spacer grids together with the four " corner " fuel rods are fabricated into a sub-assembly which is supported at the bottom of the fuel element and is able to expand and contract with temperature change, independently of the casing 11. The "corner" fuel rods are made up from sections corresponding in length to the longitudinal spacing between spacer grids. One section terminates above a spacer grid with an end cap formed with a screw - threaded spigot engaging a screwthreaded aperture in an end cap of the section below the spacer grid. The latter end cap has a recess in which is accommodated the arcuate portions of a corner cell 17 of the spacer grid, the cell being of generally cruciform section and secured by either spot welding or brazing on two adjacent sides to sides 3 of adjacent cells 2 and on the remaining two sides to the surrounding strip 9. A shim is provided between abutting faces of the end caps of the two rod sections and serves also to retain the arcuate portions of cell 17 in the recess. A locking pin is employed to prevent unscrewing of the rod sections. In an alternative construction, the grid is similar to that described above, but instead of having a square boundary has an octagonal one with alternate sides twice as long as the remaining sides. This is accomplished by leaving out the corner cells and incorporating suitably shaped strip members which are secured to two of the outer cells as well as to the octagonal surrounding strip. In both constructions, the spacer grids may be longitudinally located relative to the respective fuel element casing by securing each grid directly to the casing.

Filed: 1971-09-27
Abstract: 1323529 Ground navigation aid SPERRY RAND CORP 27 Sept 1971 [16 Oct 1970] 44855/71 Heading H4D To direct an aircraft 1, Fig. 1, along a path 2, 3, 5 and command its pilot to stop at the end of the path, the aircraft is provided on its nose with an area 8 of photoluminescent material which, when illuminated with an ultra-violet source 16 flashing at 120 per sec., glows and emits corresponding flashes of visible light. The light is focused initially on a split photovoltaic detector 42, 43, Fig. 6, directed along path 2 at position 6 so that the position of the light image 4 on the detector, and thus the lateral position of the aircraft with respect to the path 2, is given by the output of a subtractive amplifier 47a receiving the output of the detector halves via filter and fixed phase shifters. The outputs are also summed at 47 to give an aquisition signal. A quadrant detector 61, 62, 63, 64, Fig. 7, at positions 7 and directed along path 5, detects when the area or aircraft 8 reaches the turning point 3 and causes a " turn-left " instruction to be given to the pilot. The detectors track the aircraft in elevation and are grouped in pairs C/F and D/E to give a lateral deviation signal from demodulator 78 and in pairs C/D, F/E to give an " up-down " deviation signal from demodulator 79. Since the detector body 15, Fig. 2 is directed downwards, the detection of a certain attained elevation angle indicates that the aircraft has arrived at the stopping point, whereas a "stop" instruction is given to the pilot. About 20 yards before the stopping point is reached a " slow-down " instruction is given to the pilot. The signalling systems to the pilot are shown at Fig. 4 for position 6 and at Fig. 5 for position 7. The green " on course " lights 26, 30 are energized by the respective acquisition signals on lines 49 and 80 and the lateral deviation light by the respective demodulation output signal on lines 56, 81. The " updown " deviation signal on line 82 energizes the motor scanning detector 15 to track the aircraft. The elevation angle of the tracking detector 15 determines when the amber " slow " and the red " stop " lights should be energized. The " go left " light 27a is caused to blink when the aircraft reaches point 3.

Abstract: 1396569 Variable frequency dividers ADRET-ELECTRONIQUE 16 Oct 1972 [18 Oct 1971 31 Dec 1971(2)] 47577/72 Headings G4D D7X D6Y and D6C1 A frequency divider comprises a first division stage which divides by a factor M or M + 1 according to whether a zero or one level is present at an input C and a second counting stage 2 arranged to deliver a "one" output to C for N-n of every N pulses supplied to it by the first stage, n being variable to set the division ratio of the divider. In this simple form the divider thus divides by MN + n. For convenience N may be made equal to 10, n is variable from 0-9; then if M is for instance made equal to 3, the divider divides by a ratio variable from 30 to 39. In Fig. 2, the division stage 1 is provided by three J-K flip-flops 4, 5, 6, one of which 6 has an internal AND-gate 6a connected to two J inputs. With the connections shown the stage divides by 2 when C26 is at zero level and by 3 when C26 is marked (i.e. M = 2). By providing further flipflops 5 the value of M can be increased; by switching the additional flip-flops in and out the value of M can be varied, Fig. 4 (not shown). The counter 2 may include a decade counter and a comparator comparing the count with the set value n. In order to make the division ratio adjustable over different ranges (e.g. from 33 to 42 instead of 30-39), the division stage 1 may be arranged to divide by M, M + 1 or M + 2 depending on whether two terminals are marked. The counter 2 is provided with a second comparator, Fig. 9 (not shown), and means for setting in a further value p. One terminal is then marked when the count exceeds n and both terminals when it exceeds p; the divider then divided by MN + n +p. The value p may be provided by a fixed arrangement of logic gates, Fig. 10 (not shown). The division stage may be provided by a suitably connected shift register. The output at terminal S of Fig. 2, &c. is an unsymmetrical squarewave. Further arrangements, Figs. 11, 12 (not shown), provide a symmetrical waveform (substantially equal mark/space).
