Title: Improvements relating to x-ray spectrometry
Inventor: AB EMIL ANATOLIEVICH
IPC: G01N23/223
Filed: 1968-07-12
Abstract: 1,219,448. X-ray diffraction apparatus. VSESOJUZNY NAUCHNO - ISSLEDOVATELSKY INSTITUT RAZVEDOCHNOI GEOFIZIKI. 12 July, 1968, No. 33298/68. Heading H5R. [Also in Division G1] A spectrograph comprises a unit for detecting and recording the secondary radiation emitted by a specimen and an X-ray tube assembly which has at least two individually selectable target areas each area having a different emission spectrum, a set of filters being situated between the X-ray tube assembly and the specimen and being individually interposable at will so as to irradiate the specimen consecutively with a beam of monochromatic radiation of desired wavelength. The X-ray tube 1 may have an anode 8 formed with two or more target areas 9 of different metals which metals give different emission spectra when exposed to the electron beam from the cathode. The required target area may be selected by means of a magnetically operated selector 12 or 18 which selector as shown in Fig. 3 may be such as to deflect the electron beam to a desired target or as shown in Fig. 2 the targets may be mounted on a carrier within the tube which carrier is movable by magnetic means 12 to position a desired target in the path of the electron beam. In a further embodiment (Fig. 4, not shown), the X-ray beam emitted by the tube is incident upon a selected one of a number of target areas individually positionable in the beam. The support for the target areas in this case is a polygonal prism having the different materials attached to its surfaces and rotatable to position the desired material in the X-ray beam and direct it towards the filter array. In another arrangement (Fig. 5, not shown) two X-ray tubes with different targets are used as the X-ray source, the beams from each tube being either shielded or allowed to pass through appropriate filters as desired. The unit for detecting and recording radiation is described in the Specification as containing a detector, a supply generator, amplifiers, discriminators and a recorder but none of these are particularly illustrated or described. The device 14 shown in the figures is for checking the radiation intensity of the tube, and comprises a photo-resistor powered by a dry cell and connected to a galvanometer.
Patent GB-830889-A (GB)
Title: Improvements in or relating to a shell fuze
IPC: F42C15/22
Filed: 1958-10-20
Abstract: 830,889. Ammunition fuzes. JUNGHANS A. G. GEB. Oct. 20, 1958 [Oct. 18, 1957], No. 33409/58. Addition to 788,628. Class 9(1) The clockwork fuze described in the parent Specification having a firing pin 13 held at safe during the initial part of the trajectory by engagement with a pivoted latch 39 having a depending arm 39b is immobilized by abutment with a control pin 38 mounted on a lever 100 which is a modification of the lever shown in the earlier Specification. Lever 100 pivots about a pin 101 and has unbalanced arms 100a, 100b<SP>1</SP>, the heavier arm 100a producing a torque on the lever in a counterclockwise direction and the arm 100b<SP>1</SP> bearing against a centrifugal weight 102 carrying a rack 104, which meshes with a pinion 23 controlled by the clockwork mechanism. The weight 102 slides between guide surfaces and its length abutting the lever 100 corresponds to the predetermined safety margin, after which the lever is freed. A passage 300 for the firing pin 13 blocked by a rotor 303 mounted on a shaft 304 is aligned with a tetryl detonator 302. A bore in the rotor contains a heavy metal insert 305 causing the rotor to rotate under centrifugal force until a primer 301 is aligned with the pin 13 and the detonator 302, the motion of the rotor being halted by its surface 303a impinging against a pin 306. In the position of rest a blind bore 303b is aligned with the pin 13. Movement of the rotor is initially prevented by a latch pin 309 bearing against a milled surface on a shaft 308 to which is keyed a lever 307 engaged in a notch in the weight 102. When the bolt 102, 104 driven by the pinion 23 reaches its outer position, the lever 100 is released and control lever 307 rotates so that the latch pin 309 is freed and the rotor can rotate to the armed position. To prevent unintentional ignition should the fuze head be removed from the lower portion, a safety member 310 is placed in a transverse bore of the fuze base, the member 310 being apertured to receive pin 13 and being held in position by a pin 311 projecting from the fuze head. If the fuze head is removed, the rotor rotates and the member 310 moves until it covers the primer 301.

Title: Improvements in or relating to gas-blast electric circuit-breakers
IPC: H01H33/825
Filed: 1945-12-18
Abstract: 605,217. Gas-blast switches. REYROLLE & CO., Ltd., A., and AMER, D. F. Dec. 18, 1945, No. 34216. [Class 38 (v)] In a gas-blast circuit breaker having a gas delivery-chamber or reservoir on the highpressure side of a nozzle, and a blast-valve at the outlet side of an exhaust-chamber on the low-pressure side of the nozzle, an exhaust-valve is arranged in tandem with the blast-valve, the valves being sequentially-controlled by a single control-device, so that during opening of the breaker the blast-valve is opened before the exhaust-valve is closed, and during closure of the breaker the exhaust-valve is opened before the blast-valve is closed. In Fig. 1 a rotary control shaft F in the base of a post insulator A, is connected through a crank F<1> and an insulating rod F<2> to the exhaust-valve C<4>, and through toggle-linkages C<5>, E' to the blast-valve E and a pair of series-connected movable-contacts G. The breaker is opened by rotation of the shaft F, the valve E opening before the valve C' closes, arid before the contacts G, D<2> separate, so that gas flows through the exhaust-chamber D, an expansion-chamber C, and a non-return valve C<1> to atmosphere. When the valve C<4> closes the contacts G, D<2> separate, and a stream of arc-extinguishing gas flows from the reservoir B through the nozzles D<1>, and expands into the chamber C, the build-up of back-pressure in the chamber D being delayed until the arc is extinguished. The exhaust-gases are, for the most part, held and cooled in the chamber C until the breaker is reclosed, the valve C<4> then opening before the valve E closes, so as to discharge the exhaust-gases and at the same time scavenge the chambers D, C. As the togglelinkage E<4> re-closes the contacts G, the valve E closes and restores the pressure in the chamber D. In metal-clad withdrawable switch-gear, Fig. 4, the expansion-chamber H and exhaust-chamber J are arranged wholly within the reservoir L, and the chamber J has an extension J<2> with nozzles J<3>, J<4>, in alignment with contacts K, K<1>, the extension J<2> being connected to the contact K<1> through a resistance M<2>. In an open-type circuit-breaker, Fig. 5 (not shown), the movable-contact co-operates with nozzles arranged in opposite walls of a plurality of conduits which communicate with the exhaust-chamber. In Fig. 6 (not shown) the contacts are arranged outside the reservoir, which has a cam-operated inletvalve, automatically-operable under fault-conditions.

Filed: 1974-08-05
Abstract: 1460475 Treating exhaust gases NISSAN MOTOR CO Ltd 5 Aug 1974 [17 Aug 1973]  34352/74 Heading F1B [Also in Divisions Bl and F4]  An I.C. engine with means for reducing the concentrations of harmful substances in its exhaust gas before emission to the atmosphere and having an even number of combustion chambers 11 to 14, comprises an exhaust manifold 40 in communication with the combustion chambers and having an outlet 45 leading to a thermal reactor 50 having a cylindrical inner body 51 forming a reaction chamber 54 and a cylindrical outer body 52 with a discharge port 60. The space 53 between the inner and outer bodies communicates with the reaction chamber 54 through holes 56 in the ends of the inner body. Means are provided which act so that the exhaust manifold discharges two differently composed exhaust gases alternately as a consequence of the firing sequence of the combustion chambers, the first exhaust gas containing larger amounts of carbon monoxide and unburned fuel than the second, which contains a larger amount of air than the first. In a four cylinder engine, rich mixture may be fed from a carburetter 25 to combustion chambers 11, 14 and weak mixture fed from a carburetter 26 to combustion chambers 12, 13, so that during the firing sequence 11-12-14-13 exhaust gases alternately rich and weak in carbon monoxide and hydrocarbons are fed to branches 41, 42, 44 and 43. A dividing wall (62) Fig. 2 (not shown) and dividing wall (63) may be provided so that the first type of exhaust gas from cylinder 11  is mixed only with the second type of exhaust gas. from the cylinder 12. Instead of carburetters 25, 26, a fuel injection system may be used to provide the cylinders 11, 14 with different quantities of fuel from those supplied to the cylinders 12, 13. Instead of feeding different amounts of fuel to the cylinders, each cylinder 11-14 may be supplied with the same amount and secondary fuel supplied to branches 41, 44 of the exhaust manifold by fuel injection nozzles 71, the amount of fuel fed thereto being preferably proportional to the amount of air fed to the engine 10. Branches 41, 44 may be provided with air nozzles 81 fed via a normally closed solenoid valve 83 opened when the load on the engine falls to a predetermined value such that thetemperature of the exhaust gas from cylinders 11  and 14 is too low to achieve the required reaction in the reactor 50. The enrichment of the exhaust gas could be accomplished by reducing the air-fuel ratio of the mixture fed to cylinders 11, 14 or by employment of the fuel nozzles 71 which are normally partly open and are controlled to open further as engine load falls. The engine may have more than four cylinders.

Filed: 1934-11-30
Abstract: 449,949. Impedance networks. PAGE, H., Radio Research Station, Slough, Bucking- hamshire. Nov. 30, 1934, No. 34484. [Class 40 (iii)] A four-pole network comprising ideal transformers T1, T2, Fig. 2, and two impedances B, G, is so dimensioned as to be equivalent to a lattice section having desired characteristics and composed of four complex arms of the same impedance-type as B, G. The reduction in the number of impedance elements facilitates the use of adjustable meshes. In phase-retardation, networks the arms may comprise inductance and capacity respectively Fig. 3b, (not shown) or one impedance may be an acceptor circuit and the other a rejector circuit, Fig. 4b, (not shown). In a variable attenuator Fig. 5b, (not shown) the impedances B, G, are variable resistances. The invention may be applied to the design of wave-filters Figs. 6a, 6b, 6c, (not shown). The transformers T1, T2, may have the same or different transformation ratios. A number of sections such as that shown in Fig. 2, may be connected in tandem, Fig. 7a, (not shown) but the outer coils p may be omitted, Fig. 7b, the inner coils s of adjacent sections being wound on a common core except in the case of the end connections. Jacks and patching cords may be provided, Fig. 7c, (not shown), for isolating individual sections for testing, the transformer ratios being such as to ensure that the impedance shall be the same at each tapping. A section with variable phase delay may be connected in tandem with a number of more complicated sections that give fixed phase delay. Instead of a number of sections in tandem, one section of the kind shown in Fig. 2 may be used, G comprising a number of meshes in series, Fig. 8, (not shown).
