Title: Safety lock
IPC: G21C19/18
Filed: 1975-07-15
Abstract: 1499430 Fuelling reactors KRAFTWERK UNION AG 15 July 1975 [16 July 1974] 29719/75 Heading G6C A safety lock for enabling a fuel element to be engaged into or out of the interior of a nuclear reactor, without exposing the interior to the exterior, comprises a lock tube 3 which extends through a spherical steel safety envelope 1 of the reactor (p.w.r.), and also through an external concrete building 2 surrounding the safety envelope 1. The fuel element is carried by a carriage 11 which can be run directly through the lock tube 3, two identical rod drives 14, 15 being provided at the two ends of the tube 3 and associated with a pivoting device 9, 16 in internal and external fuel element storage tanks 8, 17, respectively. Only the drive 15 is shown in detail, drive 14 being however of similar construction. Drive 15 includes a rack 20 engaging at one end with a pinion 29 turned by a driving shaft 30 so as to be displaced longitudinally within a tube 23. Rack 20 is connected to carriage 11 by means of a latch 31 which can be brought into or out of engagement with a groove 32 in the carriage 11 by turning the rack 20. Rotation of the rack 20 is effected by rotating the tube 23 which is secured to a bevel gear wheel 25 turned by means of a second bevel gear wheel 26 on a driving shaft 27. After the first rightleft movement of the carriage 11, the rack 20 is run back to its original position whereupon the latch 31 can engage in a groove 36 provided at the opposite end of the carriage 11 to the groove 32. Consequently, in two successive steps the carriage 11 can be moved to a position 34, i.e. a distance of twice the rack travel. An external lock gate 37 is then closed, after which an internal lock gate 38 is opened and the internal rod drive 14 operated to draw the carriage 11 on to the pivoting device 9. The transport of the carriage 11 in the reverse direction, i.e. from left to right out of the safety envelope 1, is carried out in a similar manner, except that the internal rod drive 14 first pushes the carriage 11 into the lock tube 3, from which it is then withdrawn by the external rod drive 15.

Abstract: 1467473 Timepiece gearing; chronographs SOC SUISSE POUR L'INDUSTRIE HORLOGERE MANAGEMENT SERVICES SA 4 July 1974 [10 July 1973] 29730/74 Heading G3T In a timepiece having a rotary shaft 1 with a toothing 11 engaged or engageable with a driving wheel 12, the shaft is pivoted with play in a bearing 4 and has a shoulder 13 engaged by a spring 14, the spring force having an axial component and a lateral component which presses the shaft toward the axis of the wheel 12. The root portions of the toothing 11, which is of involute form, are thus pressed against the tooth tips of the wheel 12, or vice versa, to eliminate backlash and ensure accurate starting of the shaft 1 when driven. As described the shaft is a chronograph seconds shaft, but application to an indirect drive of a minutes hand is also envisaged. The axial pressure on the shaft maintains clearance between a heart-piece 10 and a frame plate 7. The other end of the shaft is supported in a cannon pinion 6. The bore of bearing 4 is elongated in one direction only.

Title: Device for statically measuring the mean density of a liquid circulating through a system of conduits
IPC: G01N9/26
Filed: 1970-06-22
Abstract: 1,270,053. Apparatus for measuring density of flowing liquids. SOC GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES (ALSTHOM). June 22, 1970 [June 27, 1969; Nov. 28, 1969; April 9, 1970], No.30236/70. Heading G1S. Liquid hydrocarbon tapped from a conduit 31 via a pressure reducing valve 33, enters a tube 44 or first column and overflows at its top 35 into a return pipe 37. A reference liquid within an inner tube or second column acts against a membrane 45 separating the liquids and balances the head of the liquid hydrocarbon in the outer tube. Should the density of the hydrocarbon alter, then the equilibrium or balance of the liquid columns is disturbed and the position of a deep float 46 alters because of the different pressure head acting on the membrane 45 and operates a lever 47 which controls an electric motor 38, which motor raises or lowers the movable tank 36 and the surface N' of the liquid hydrocarbon to rebalance the liquid columns. The movement of the tank 36 necessary to adjust is read off on a gauge 43 to indicate the density alteration. In Figs. 1-3 (not shown) the columns are separate instead of concentric and slightly different ways of equalizing the levels N and N' are described, the lifting and lowering of the tank being carried out by a piston servomotor (22) for example, or the lever mechanism operated by the float being used instead to control the opening of a valve (25) Fig. 4 (not shown) regulating admission of hydrocarbon into the top of the first column. In Fig. 6 the fluid to be measured flows via pipe 52 and valve 53 into an upper overflow 56 of a movable tank, the overflowing liquid returning via pipe 57. The base of the first liquid column 54 is however connected via a flexible pipe 66 to a second overflow 65 so that there is a circulation of liquid downwards in the column 54, up the conduit 66 and out of the overflow 65, this circulation being effected with a constant pressure loss which is independent of the variations in flow-rate and so on. A concentric reference liquid tube and diaphragm are provided as before, but the constant loss of pressure due to the downward flow in the column 54 must be allowed for and this is determined by closing the valve 67 to stop the circulation and measuring the static height of the column to find the difference between this static reading and the circulatory reading. The corrective term thus determined must be subtracted from the normal reading obtained from the difference of the levels N, N' as read from the gauge 63.

Title: Improvements in or relating to sonic gas analysers
Inventor: MOUNFIELD DONALD
IPC: G01N29/024
Filed: 1954-10-25
Abstract: Relates to a sonic gas analyser in which the composition of a sample gas comprising a mixture of two gases is determined by measuring the phase difference between two electrical waves corresponding respectively to sound waves (1) emitted from a transmitter and received at a spaced receiver, (2) received from a single transmitter at two separate receivers spaced apart in the sample gas, or (3) received at two separate receivers spaced at equal distances from a single transmitter or two similar transmitters, one transmission path being in the sample gas and the other being in a datum gas, Fig. 5 (not shown); the transmitter(s) and receivers each comprise electroacoustic transducers and the transmitter is energized by a sinusoidal oscillation of constant frequency.  According to the present invention the phase meter is calibrated by inserting an adjustable phase shift corresponding to a given gas composition in the path of one of the electrical waves applied to the phasemeter. As described, the two electrical waves are each squared and differentiated to produce two corresponding trains of negative pulses, Fig. 1 (not shown), which control a trigger circuit producing a train of pulses each of duration proportional to the phase difference to be measured, the pulse train being applied to a meter indicating the average value of the current, and the required calibration phaseshift being effected by adjusting the time constant of an R.C. coupled amplifier, Figs. 2-4 (not shown), preceding the shaping circuits.
