Title: Improvements in or relating to range keepers or like instruments
IPC: F41G5/14
Filed: 1919-06-17
Abstract: 151,089. Kilburn, B. E. D., (Ford Instrument Co.). June 17, 1919. Range and bearing keepers.-Relates to rangekeepers and like instruments of the type in which there are two sector members each of which can be set with respect to the line of sight between the ship and the target, and also means for rotating the line of sight, and comprises means whereby not only is a reading of range constantly given, at 37, Figs. 1 and 4, but the rates of change of range and of deflexion are also shown by means of dials 34, 31 respectively. These last indications are obtained by means, whereby, in effect; the vectors representing the ship's and target's speed and direction are resolved along and perpendicular to the line of sight 36 joining the ship and target, the pairs of resolutes are added together. The ship and target pointers 23 are mounted on dials 21, 26 inside compass rings 22 and 27, the dials and rings rotating together or independently. In actuation, the ship's pointer is brought into the fore-and-aft line of the ship, wherein it is maintained; the two pointers are set parallel to the ascertained directions, the compass rings are set N and S, and members such as 47 are set beneath their respective dials along screws 44 till pointers 25, 29, Fig. 1, attached to them indicate the speeds of ship and target on scales 24, 28 respectively. The sighting-device 17 is then kept trained on the target, the casing 1 to which it is attached turning with it. Turning of the casing, Fig. 3, orients two sets of slides 74, 74<1>, 76, 76<1> arranged parallel and at right-angles respectively to the line of sight. These slides are connected as shown to pins 72, 72<1> depending from the members 47, which therefore, in their setting, traverse the slides and through racks 83, 84 and differential mechanism rotate shafts 82 and 90 from which the deflexion and range rate dials 31, 34 are set, giving an indication of the sum or difference of the two pairs of resolutes. The spindle 91, Fig. 4, of the dial 34 on being set also positions the rack 155 and therefore the operative member of the ball-and-roller integrating-mechanism shown in Fig. 4, rotation of the roller 147 being transmitted to the counting-device, which can be set fcr an initial reading of range by means of a handle 170. The setting of a friction disk 121, Fig. 4, by means of a cam 126, regulates the governor and therefore the rate at which the driving-wheel 108 of a spring drum drives the integrator disk 100. The ball-androller mechanism actuated by the disk 100 is shown in Fig. 7 and comprises two steel balls 145, 146 in rolling contact with each other and with the spring-pressed roller 147 and the disk 100 respectively; the balls 145, 146 are mounted in a cage 152 which is provided with rollers 153 holding the balls so that the points of contact between themselves and the disk and roller are in alinement.

Title: Device for centring fuel elements in nuclear reactors
Inventor: BOUDOURESQUE BERNARD
IPC: G21C3/08
Filed: 1963-04-19
Abstract: 960, 813. Nuclear fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. April 19, 1963 [April 20, 1962; July 20, 1962], No. 15560/63. Heading G6C. A device for centring a fuel element provided with an external sheath comprising fins arranged in herringbone form in relation to an annular structure surrounding the element is composed of at least three centring blades, of which the centre planes are directed towards the axis of the element, and which are fast with the structure and in contact with the sheath, or vice versa. As shown in Fig. 7, the fuel element 2 comprises a tube 4 of fuel material, e.g. pure or lightly alloyed uranium, closed at each end by a uranium pellet 6 and enclosed in a sheath 8 on the outside surface of which are fins 17 arranged in series forming herringbone patterns with a longitudinal groove 18 between each two successive series. There are three centring blades 20 engaging three alternate grooves 18. The sheath 8 may, for example, be of Mg-Zr alloy of low Zr content and is closed by welded plugs 14 which may, for example, be of Mg-Mn alloy of very low Mn content. The element is supported within an annular sleeve 26 to form a fuel cartridge by means of a central plug 30 suspended in the sleeve by a series of crossed wires 32. These wires have sufficient flexibility to damp the shocks to which the element 2 is subjected during loading and unloading operations. In this construction, the blades 20 are prevented from rotating within the sleeve 26 by being engaged within longitudinal slots 34 in the inside wall of the sleeve. In addition, the blades 20 are prevented from slipping in a direction parallel to the axis of the element by means of teeth 24 integral with the blades which engage in radial recesses 36 of greater depth than the corresponding slots 34. Alternatively, the blades 20 may be directly welded to the sheath 8 or to the sleeve 26. Since herringbone-type sheaths eliminate the aerodynamic forces which tend to turn the fuel element within the coolant channel, the gas flows which they induce being symmetrical in pairs, the centring blades 20 have to exert no opposing torque and it is sufficient for them to have adequate rigidity in the longitudinal and radial directions. In order to reduce the neutron absorbtion, the blades are provided with recesses 22 either of semicircular, trapezoidal or rectangular form, or as simple holes in the blade. Advantageously, the blades 20 are tapered inwardly at their edges engaged in the longitudinal'grooves 18 of the sheath.

Title: Method and apparatus for controlling the uniformity of cigarettes
IPC: A24C5/34
Filed: 1952-06-20
Abstract: 741,932. Cigarette-making machines. AMERICAN MACHINE & FOUNDRY CO. June 20, 1952 [Aug. 2, 1951], No. 15561/52. Class 130. [Also in Groups XXXV and XL(b)] In a cigarette-making machine the uniformity of cigarettes produced is controlled by passing the moving stream of tobacco through an X- ray, # ray or a ray beam of penetrative radiation, detecting the amount of radiation passing through and operating a control of the machine to reject over or under weight or otherwise defective cigarettes. As shown the mass or density of a continuous cigarette rod R is measured by a shielded source of radioactive material, e.g. the radioactive isotope strontium 90, producing # rays which pass in a beam of known cross-section through the rod to an ionisation chamber 102 filled, e.g. with argon and carbon dioxide for fast ionisation response. The chamber output is passed through amplifying stages to an integrating or averaging circuit which controls the setting of the contact arm of a zero-centre meter, as described in Specification 323,226, [Class 135]. Dependent on the direction of movement of the contact arm, a motor is driven one way or the other causing a drive unit to increase or decrease the speed of the feeding apparatus of the machine to render the rod uniform and at the same time, as described in Specification 438,997, [Group XXXV], a fast-acting relay is energised by the amplifier to set in operation a timing disc and index mechanism which drives a sprocket 46 and gearing 42 and sets in rotation rejector rods 32 mounted on a pivoted arm 37 simultaneously lowered by an arm 78 from the timing mechanism. The lowered rejector rods deflect in midair defective cigarettes which, ejected from a guide channel 22, would otherwise fall on a conveyer belt 24, to an ejector shoot 80. As shown the detector preferably is arranged between the rod sealer S and cut-off knife C. Dense portions or hollows of the cigarette rod also result in operation of the relay, timing mechanism and rejector device.
