Title: Safety Rods for Nuclear Reactors
Inventor: PARATESI SERGIO GALLI DE
IPC: G21C7/22
Filed: 1967-03-09
Abstract: 1,161,454. Controlling reactors. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). 9 March, 1967 [22 March, 1966], No. 11151/67. Heading G6C. A system of liquid safety rods for a nuclear reactor comprises a set of hollow rods I to N which pass vertically through the reactor core 2 and open above the core into a top header 1 and below the core into at least one bottom header 10, the latter being connected through a valve (not shown) to a neutron poison solution accumulator 9 at the upper end of which is an inlet 54 for pressure gas used to drive the poison solution down to the bottom header 10 and up the rods I to N. The speed of movement of the solution is controlled by hydrodynamic brakes 53-I to 53-N. A tube 19 extends from within the accumulator 9, slightly above the level of the bottom header 10, to the top header 1 and prevents the pressure gas from bubbling through the safety rods which would otherwise occur when the level of the solution in the accumulator 9 reached the level of the bottom header 10 and of the bottom ends of the rods. The accumulator 9 is connected by means of valves and pumps to both a poison solution reservoir and a washing liquid reservoir (not shown) so that poison solution or washing liquid can be circulated in the accumulator 9 and the rods I to N communicating with it. The rods I to N enter the top header 1 for a short distance and all terminate in the same horizontal plane while the bottom of the header has a slight slope (Fig. 1, not shown) so that washing liquid spurting into the header through the top ends of the rods being washed is drained towards an orifice 5. Thus the washing liquid cannot enter the other rods which are held in reserve in case the reactor should have to be stopped, or are already filled with poison solution. The pressure gas is fed through a conduit 11 via a 3- way control valve 12 from an accumulator 13 fed through a valve 14. During normal reactor operation, the valve 12 connects the conduit 11 with a conduit 16 leading to a low-pressure source. The accumulator 9 has a valved overflow pipe 18 during normal operation maintains the solution in the accumulator 9 at the level 7 of the bottom of core 2. In order to shut down the reactor, the valve 12 is changed over and gas from the accumulator 13 drives the solution through the rods I to N. In one embodiment, there are two accumulators 9, one of which is held in reserve should it be desirable to wash the other and each is connected to a separate bottom header 10 into which the rods open through valves. In an alternative embodiment, the rods are distributed in groups each connected to its own accumulator 9 through its own bottom header 10. When an accumulator and its rods are washed, the remainder are sufficient to ensure shut down of the reactor.

Abstract: 769,949. Electromagnetic relays. ERICSSON TELEPHONES, Ltd., and DISTIN, L. S. April 19, 1955, No. 11220/55. Class 38(5) The armature 9 of a miniature relay is pivotally supported by an arcuate torsion spring 16 fixed at one end by a screw 20 to end cheek 11 of the coil 10, a spacer 19 being ionterposed.

Title: Pressure control mechanism applicable to pressurized aircraft cabins
IPC: B64D13/02
Filed: 1951-05-15
Abstract: 695,065. Fluid-pressure servomotor-control systems. GARRETT CORPORATION. May 15, 1951 [May 23, 1950], No. 11289/51. Class 135 Mechanism for controlling a pressurized aircraft cabin has means for limiting the rate of change of pressure over a predetermined range of altitude and thereafter maintaining the pressure constant. As shown, a spring-loaded cabin outlet valve member 15 to which is attached a flexible diaphragm 23, is controlled by pressure in a chamber 27 which is connected by a conduit 67 to a control chamber 38 having a restricted connection 42 with the cabin, an outlet 47, 60 to atmosphere controlled by a valve member 57, and a restricted connection 97, 95. 98 with a chamber 37. The valve member 57 is actuated by a diaphragm 39 separating the chambers 37, 38 and has a spring connection 76 with a lever 75 pivoted at 77 and connected to an evacuated bellows 70 and an adjustable spring 85. In operation, the spring 85 is adjusted before takeoff according to the altitude at which the pressure is to remain constant, this adjustment causing the bellows 70 to collapse and the lever 75 to engage a stop 90. As the aircraft climbs, the consequent lowering of the pressure in the cabin causes a reduction of pressure in the chamber 38 and a flow of air from the chamber 37 to the chamber 38 at a rate determined by the setting of a valve member 103 in the connection 97. 95, 98. The downward loading imposed by the spring 76 upon the diaphragm in conjunction with the pressures acting on either side of the diaphragm causes the latter to operate the valve member 57 to maintain a constant pressure difference across the connection 97, 95. 98 and therefore a constant rate of leakage from the chamber 37 and a constant rate of change of pressure in the chamber 38, in the chamber 27, and consequently in the cabin. When the pressure in the chamber 37 has fallen to that value at which it is required to maintain the cabin, the evacuated bellows 70 expands and relaxes the tension of the spring 76 to allow the pressures on either side of the diaphragm to become equalized. Control of the cabin pressure is then effected by the bellows 70. For controlling the rate of change of pressure during descent, the spring 85 is set initially to expand the bellows 70 and bring the lever 75 against a stop 91. Specifications 655,601 and 664,143 are referred to.

Title: Improvements relating to the flame-photometric testing of flammable gases and apparatus therefor
IPC: G01N21/72
Filed: 1955-04-19
Abstract: <PICT:0779212/III/1> In a known method of determining the constituents of a flammable gas in a line 1 the flow passes from line 4 to two branches 5, 6. Branch 5 feeds a measuring flame 33 while branch 6 is again split to branches 7 and 8 one of which is unaffected while the other passes through material 9 absorbing the constituent to be determined.  The latter two streams are recombined in tube 10 and feed comparison flame 34.  The intensity of these flames is compared by photo-cells 37, 38 potentiometer 39 and voltmeter 40. According to the invention the device 14 comprising a differential pressure-responsive diaphragm and valve 16 maintains the ratio of the flow in the branches 5 and 10 constant.  Valves 56 and 60 enable the replacement of material 9 by material 58 as desired. Branches 12 and 13 contain "flow meters" and flow indicators 42, 43 and device 11 maintains the ratio of the flow in these two branches constant.  In the modification described with reference to Fig. 2 (not shown) the flow in branch 10 is adjusted instead of that in branch 5.
