Title: Improvements in/or relating to the selective detection of fission products in a gas flow
Inventor: GOUPIL JEAN
IPC: G01T7/06
Filed: 1958-12-01
Abstract: 851,328. Nuclear reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE Dec. 1, 1958. [Dec. 4, 1957], No. 38707/58. Class 39(4). In a nuclear reactor cooling gas monitor, the short-lived fission products are detected to indicate the fracture of fuel element sheathing. The effect of the long-lived fission products is iluminated by a fuel recording circuit. The short-lived products decay first to krypton and zenon and then to rubidium and caesium ions which are collected so as to develop a signal separate from that due to the long-lived products. A signal corresponding to general level of radioactivity of the gas is first produced and then compared with a second signal corresponding to the general level plus the activity due to the short-lived products. As shown, a proportion of the coolant passes through chambers 1 and 2 where detection of the fission products is effected by scintillator 7, the output of which is applied to comparator circuit 13, 16. The long and short-lived products pass through 1 and 2 and the signal representing the general level of activity is applied simultaneously to amplifiers 13, 16 and a zero reading is recorded at 21. Next, the valves 3, 4 are closed, a voltage is applied to electrode 5 and the rubidium and caesium ions of the short period fission products resulting from decay in chamber 1 are collected at 5 and produce an additional signal which is applied only to valve 13. The resulting unbalance of 13, 16, being a measure of the short-lived products, is registered at 21.

Abstract: 843,411. Radio navigation. COMPAGNIE GENERAL DE TELEGRAPHIE SANS FIL. Dec. 13, 1957 [Dec. 20, 1956], No. 38795/57. Class 40(7). Relates to means which utilize a hyperbolic radio navigation system as described in Specification 620,479 and a receiver phasemeter as described in Specification 620,480 and which indicate to a navigator that a predetermined course is being held. If the vehicle's speed is known the mean rate of change of phase across a portion of the hyperbolic set produced by two transmitters is calculated and the indicating phasemeter's field is held stationary either by mechanical counter-rotation of its armature, Figs. 2-5 (not shown), or electrically by a counter-rotating field from auxiliary coils on the armature, Fig. 6 (not shown). In another embodiment a rotatable disc with an index segment and coaxial with the phasemeter's dial is driven by an adjustable-speed motor, the navigator checking that the desired course is being followed by reference to a steering compass and adjusting the motor speed until the phasemeter pointer and the disc index rotate in synchronism continuation of which shows correct steering, Fig. 7 (not shown). In a further embodiment two hyperbolic sets are used, Fig. 8 (not shown): disc 83 is rigidly mounted on the shaft of phasemeter 81 and a disc 84, coupled to disc 83 by a transmission ratio calculated from the hyperbolic geometry and desired course, rotates independently of the shaft of second phasemeter 82. Steering is controlled so that pointer 89 remains in line with index 88 after their correspondence has been initiated by running on the desired course ascertained from the steering compass. The transmission between discs 83 and 84 may be effected by a selsyn system, Fig. 10 (not shown).

Abstract: 1,067,885. Automatic phase-control; colour television. FERNSEH G.m.b.H. Sept. 16. 1965, No. 39559/65. Headings H3A and H4F, In an arrangement for mixing compositecolour television signals, .each including a component of colour sub-carrier frequency, an oscillator 12 providing the colour sub-carrier component of one signal is phase-controlled by a voltage derived by a phase comparison, in discriminator 6, of the colour sub-carrier signals applied to mixer 13 from coders 33, 34. This comparison is made during the colour synchronizing interval. The control signal may be applied directly to control the oscillator, Fig. 2 (not shown), or Fig. 3, may be modulated on to a carrier provided by oscillator 40. Pulse generators 27 in the central station, and 26 in the remote station provide composite synchronizing signals S which are compared in a synchronizing stage 43 to produce a control signal, having a frequency at a multiple or sub-multiple of the horizontal frequency, for synchronism generator 26 with generator 27. This control signal is added to the first control signal in an adder 42 and fed to the remote unit where the two control signals are separated out by filter 44 to control the colour sub-carrier oscillator 12 and the pulse generator 26. In a modification, Fig. 4 (not shown), the oscillator 12 is included at the central station, and the composite signal from adder 42 controls the pulse generator 26 and a further .oscillator 52 turned to the colour sub-carrier frequency. In a further modification, Fig. 5 (not shown), the remote station signal may be mixed either with that from the central station, or with one from a second remote station.

Filed: 1975-09-26
Abstract: 1521272 Photographic colour copying DURST AG 26 Sept 1975 [2 Oct 1974] 39587/75 Heading G2A An arrangement for indicating the colour filters required in a colour copying apparatus has two comparison circuits, each comparing and indicating the intensity of a first or second primary colour component with a third. As shown, the copying beam 1 is conveyed by light guides 2, 3, 4, 5 through respective colour filters 6, 7, 8, and light channels 10, 11, 12, 13 to the two comparison circuits 19, 20. Filters 6 and 9 transmit the same primary colour, and filters 7 and 8 the other two primaries. The circuits 19, 20 are in the form of resistance comparison bridges. Pairs in photoelectric transducers such as photo-resistors 15, 16 and 17, 18 form one pair of adjacent arms of the bridges, and resistors 21, 22 and 23, 24 the other pair of adjacent arms. The bridges are supplied by respective voltage sources 25, 26 across one diagonal, and the inputs of operational amplifiers 27, 28 are connected across the other diagonals. The outputs of the amplifiers are connected to respective pairs of indicator lamps 31, 32 and 33, 34. When the bridges are balanced the lamps of each pair are on at the same time and at the same intensity. Channels 10 and 13 include adjustable diaphragms 35, 36 in the form of screws. When the apparatus is calibrated by means of a test negative, the diaphragms are adjusted so that the bridges are balanced. The test negative is then replaced by the negative to be copied, and filters 6, 7, 8, 9 introduced so that the bridges are balanced, the copy then being made. The filter colours in which filtering has to be effected are indicated by the lamps lighting up more or less intensely. Filters 37, 38, 39, 40 may be placed in front of the lamps 31, 32, 33, 34 so that a direct indication of the filter colours required is given.

A method of producing a laminate of metal sheets or strips at least one of which is of copper, comprises the steps of preheating a copper sheet or strip to form a film of cuprous oxide thereon, preheating a second sheet or strip of the same or different metal, assembling the preheated metal sheets or strips and a film of a thermoplastic ionic copolymer resin interposed between them in contact with the oxide film, and, while maintaining the metal sheets or strips in heated condition, subjecting the assembly to pressure to cause the ionic resin film to bond the metal sheets or strips together. In the apparatus shown for performing the method a copper ply 10 heated by passage through a furnace 14, and a substrate ply 18, e.g. of tinplate, low carbon steel, stainless steel, or aluminium, heated by passage through a furnace 22, are brought together between pressure rolls 16, where a thermoplastic film, e.g. of an acrylic or methacrylic acid-ethylene copolymer containing ionic metal cross-linking agents such as alkali or alkaline earth metals, zinc and aluminium, is fed between them. One or more further plastics films 32, 34 may be applied to the outside(s) of the assembly between the rolls 16. The furnace 14 is gas-fired or contains quartz sodium lamps to oxidize the surface of the copper ply 10 to form cuprous oxide. The film 26 may be replaced by a pair of plastics films. In a further example the laminate includes three metal layers in turn of copper, tin-plate, and copper.
