Title: Method of and equipment for the non-destructive testing of steel products
IPC: G01N23/222
Filed: 1962-11-07
Abstract: 973,322. Testing by irradiation. HUTTENWERK OBERHAUSEN A.G. Nov. 7, 1962 [April 4, 1962], No. 42031/62. Heading G1A. [Also in Divisions H4 and H5] In order to test steel products for the presence of oxide inclusions they are irradiated with neutrons and the gamma radiation of about 6 MeV which results measured. The hard gamma radiation results from the decay of the radio-active nitrogen isotope N 16  produced when neutrons encounter oxygen. In a testing system an ion beam 2 from a source 1 is directed to a tritium target 3 which emits fast neutrons. The neutrons penetrate the metal ingot 5 substantially without attenuation and if they encounter an oxide inclusion 6 hard gamma rays are produced and detected by the use of a scintillation crystal 7 and photomultiplier 9. The pulses from the latter are fed through a height selector 11 to a recorder or instrument 10. When the sample 5 is stationary irradiation and measurement are carried out in sequence. The irradiation period being of the order of 10 to 30 seconds and the measuring period being related to the 7 second half life of N 16 . An integrated reading is made over a certain time interval. For continuous testing the irradiation position and the measuring position are offset in the direction of movement. Neutron sheilding 12 is provided round the detector which may view the sample from any direction. Several detectors connected in parallel and opposite various faces of the testpiece may be used to increase sensitivity or to locate the position of flaws by comparison of the detector signals.

Abstract: 1447259 Piling; jetting earth L L FREDERICK 11 Sept 1973 [29 Sept 1972] 42582/73 Headings E1F and E1H A pile (sheet pile as shown) comprises a main body portion 10 having conduit means 12, 13, Fig. 1, or 64, Fig. 5, for carrying a stream of lubricant, e.g. water, to a drive shoe 46, Fig. 4, which is mounted on the lower end of the body portion 10 and which has a plurality of jets for expulsion of the water therefrom to facilitate driving of the pile. As shown in Fig. I the water carrying means comprises a pair of plates 12, 13 tack-welded to the angles of a Z-sectioned sheet pile a plurality of apertures 11 being formed along each angle. The upper ends of the plates 12, are connected to a manifold 16 and when water is pumped into the manifold under pressure, some will issue through the spaces between the tack welds across the faces of the pile. The shoe 46 is attached to the body portion 10 by rivets 50 passing through slots 48 so that relative movement between shoe 46 and body portion 10 occurs when the latter is vibrated. Water enters the shoe 46 via an adaptor 66 secured to conduit 64, Fig. 5, and reaches the shoe jets via passages 52, 54 and 58. Some water also issues upwardly between the shoe 46 and body portion 10. The intermittent sealing of the adaptor 66 against the bottom of the corresponding socket in the shoe produces a water hammer force to supplement the vibrator. In another embodiment, the pile is in the form of a double-walled cylinder, the annular space between the walls forming the conduit for the water.

As shown in Fig. 3, a photo-conductive surface 28 is charged by a corona emitting wire 55 con nected to a fixed 5000 volt supply 62. The surface potential is sensed by a probe 52 supplying a signal through an amplifier 70 and integrator 72 to an operational amplifier 73 for comparison with a reference voltage produced by a potentiometer 74. The comparator output adjusts a power source 68 supplying AC or DC between -900 and +1000 volts. The source 68 is connected to a shield 56 which controls the flow of ions to the surface 28. The apparatus operates so as to maintain a uniform charge level on the photoreceptor of an electrostatic copying machine.

Title: Improvements in or relating to the control of water turbines
IPC: F03B15/14
Filed: 1969-08-29
Abstract: 1,273,806. Fluid-pressure servomotor systems. HITACHI Ltd. Aug. 29, 1969 [Aug. 30, 1968], No.43226/69. Heading G3P. [Also in Division F1] Apparatus for controlling the flow of water to the runner 16 of a hydraulic turbine comprises a main needle valve 12 in a supply pipe 20 and an auxiliary needle valve 15 in an auxiliary supply pipe 21 by-passing the main valve 12. The valves 12, 15 are actuated by servomotors 10, 13 controlled respectively by distributing valves 7, 9 connected through linkage 3, 4, 5 to the speed governor 2. At starting and until the runner 16 and an electric generator driven thereby reach synchronous speed, valve 15 controls the flow of water to the runner and the main valve 12 is locked in the closed position. The locking is effected by mechanism 42 which is supplied with pressure oil from line f via switching valve 37 and lines g, i, a spring-loaded piston 42a in the mechanism being forced upwardly by the oil so that arm 41 engages projection 40 to prevent opening movement of the main distributing valve 7. At the same time pressure oil supplied through line h holds the arm 44 of a similar locking mechanism 45 away from a projection 43 so that the auxiliary distributing valve 9 can operate freely under the control of speed governor 2. The servosystem of the auxiliary needle valve 15 includes an elastic follow-up mechanism comprising linkage 28, 29, cam 30, dashpot 32 and linkage 35, 26, 27. As the opening of valve 15 increases during starting link 29 moves to the right taking with it the piston 38 of switching valve 37. Eventually a point is reached at which valve 37 connects line g to drain j so that the oil pressure is released from locking mechanisms 42, 45. Thus distributing valves 9, 7 are respectively locked and unlocked so that auxiliary valve 15 is locked open and main valve 12 opens to takeover flow control to the runner 16. The point of changeover is dependent upon the water head on the turbine which is detected by means 52, the latter controlling a cam 53 so as to move the body of valve 37 to the right or left relative to piston 38. The servosystem of main valve 12 includes an inelastic follow-up mechanism comprising linkage 22, 23, cam 24 and linkage 25, 26, 27. When the turbine is reversed and driven as a pump a solenoid operated valve (48), Fig. 3 (not shown), ensures that the oil pressure is released from lines g, h, i so that valve 15 is locked in the open position and flow control is by main valve 12. In a modification, Fig. 4 (not shown), valve 15 is controlled by the speed governor 2, as before, but the main valve 12 is controlled in response to load. This arrangement includes manual controls (60, 61).

As shown in Fig. 2, the tubular plastics entrance bushing insulator 23 is immersed in the emulsion at the end at which the supply conductor 28 emerges and is connected to terminal arrangement 32-38 and at its other end is carried by a metal adapter 21 which is mounted on the vessel 12 so as to maintain the whole of the insulator at the same temperature as the emulsion and the vessel 12. The cable 27 extends from the insulator 23 through an adapter 21 into a high pressure conduit 17 (Fig. 1) containing a dielectric liquid which is maintained at the same pressure as the emulsion within the vessel 12 by means of a dynamic fluid barrier 59, Fig. 3, comprising a flexible bellows element 73 which prevents the intermingling of the emulsion in conduit 61 with the dielectric liquid in conduit 62.
