Title: Improved method of loosening portable marine structure from a marine bottom
IPC: E02B17/08
Filed: 1956-05-15
Abstract: 785,277. Withdrawing piles and the like. DELONG CORPORATION. May 15, 1956 [May 16, 1955]. No. 15162/56. Drawings to Specification. Class 68(2) A portable marine structure, particularly a drilling plat-form in the form of a barge which is, in use, supported above the waves upon legs which penetrate into the sea bed, is loosened for removal to another site by lowering the platform uniformly on all the legs to float the platform, and when pulling loose a leg stuck in the bottom, loading the platform at a position opposed to the stuck leg to maintain the platform in a level condition and thus to prevent binding of the barge on the other legs. The method is described as applied to platforms having three or more legs and is modified if more than one leg is stuck in the bottom. The compensatory loading of the platform may be effected by shifting equipment, e.g., cranes, thereon, or by flooding some compartments in the platform. If a leg is stuck so fast that it cannot be freed by the use of the jack associated with that leg, then the whole platform is sunk to the minimum permissible freeboard. The jack is engaged with the stuck leg to prevent further relative motion between the leg and the platform, and the ballast tanks near the leg are pumped out, the jacks associated with the other legs being kept in readiness to grip those legs if a sudden loosening of the stuck leg tends to produce a tilting of the platform. The method of partially sinking the platform and pumping out the tanks can be used if more than one leg are stuck. When a platform is supported by more than three legs, a preliminary pull, by means of the jacks, may be made on each leg to loosen it, or to try to loosen it, before the platform is lowered into its floating condition.

Title: Reactivity pulsing device for pulsed fast reactors
Inventor: RICCOBONO GAETANO
IPC: G21C1/02
Filed: 1964-04-14
Abstract: 1,029,415. Controlling reactors. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). April 7, 1965 [April 14, 1964], No. 15403/64. Heading G6C. The reactivity of a fast reactor is varied cyclically by the periodic insertion of neutron absorbing material into the reactor core. A disc, which is mounted so as to rotate with its periphery passing through the core centre, carries spaced absorber zones round the circumference. The pulse shape is determined by the zone profiles and the reactor is subcritical when the absorber is within the core. Prompt criticality occurs when absorber is absent. To prevent an uncontrolled reaction in the event of a disc fracture, two similar discs may be mounted to rotate through the core simultaneously. B4C may be used as the absorber.

Title: Improvements in locks of the portable or padlock type
IPC: E05B37/00
Filed: 1930-05-30
Abstract: 352,170. Permutation padlocks. TREWHELLA, W., Trentham, Victoria, Australia. May 30, 1930, No. 15491. Convention date, Dec. 24, 1929. [Class 44.] A pair of members A, B are held with their ends 1, 2 in contact by a permutation locking mechanism. In the construction shown in Figs. 1, 4, 5, the members A, B are provided with interengaging teeth 5 and are retained in engagement by a recessed numeral ring 6, which can be rotated about a pivot 4 by a finger piece 4a, and a recessed inner ring F which has an abutment 16 adapted to engage an abutment 12 on the ring 6. To release the locking mechanism the numeral ring 6 is turned so that its projection 12 engages abutment 16 and moves the ring F until its recess 15 is opposite a tongue 13 on member A where it is frictionally held. The ring 6 is then reversed till its gap 14 is opposite tongue 13. In this position with the slots 14, 15 co-incident with the tongue 13 the members A, B can be separated axially. In the construction shown in Fig. 10 the front member A is provided with an oval central opening 18 and a radially projecting tongue 19 which engages with gaps 20, 21 in the inner ring F, and the numeral ring 6. Shoulders 26 prevent the members A, B from swivelling and the rings F, 6 may be mounted on a central boss which may be integral with member B or be separate therefrom and be provided with a boss to carry the fixed set of numerals. In the construction shown in Fig. 16 an unattached locking tongue 42 is seated in a slot 43 formed in a boss 39 on the member A with its ends engaging gaps 32, 31 in a boss 31 formed on the member B. Two numeral rings 35, 36 with bevelled slots 37, 38 are mounted on the boss 31 with a spring ring 40 between them. To open the padlock the rings 35, 36 are set so that the slots 37, 38 are coincident with one end 44 of the tongue 42 and then by means of a swivel movement of the members A, B the tongue is moved diametrically into slot 32 which is sufficiently wide to permit of the rotation movement. The numeral ring 35 is serrated to permit the reading of the rear numeral ring 36. In the construction shown in Fig. 23 the locking tongue 55 is exposed and provided with a projection 56 for finger manipulation. To change the combination the numeral ring R is split into two relatively rotary members 57, 57a with co-engaging teeth. The nember 57a which carries the projection 62 engaging the abutment 53 on the inner ring F, can thus be moved with respect to the member 57, which carries the set of numerals. The members A, B are locked together by projections 47 on member A which engage projections 48 on a boss 49 integral with the member B. In all constructions the various sets of numerals are arranged with different angular spacings.

Abstract: 980,467. Electric measuring bridges. ABILITIES Inc. April 24, 1962 [April 24, 1961], No. 15642/62. Headings G1N and G1U. In an instrument for measuring minute distances or changes in distance, e.g. the eccentricity of a rotatable body or the amplitude of vibration of a vibrating body, the detected output from an A.C. energized bridge 13, Fig. 3, including a pair of coils 14, 15, at least one of which comprises a measuring probe 16 the inductance of which is varied in accordance with the proximity of the body, is combined with a temperature compensating signal developed by variation in the relative resistances of the two coils 14, 15 across transistors 65, 66. The bridge output is detected in a detector 20 including filter networks 80, 81 to eliminate ripple and applied to a converter 32 which produces an A.C. analogue of the D.C. signal. The analogue signal is amplified and applied to an indicator 38 or to an oscilloscope 42. When the apparatus is applied to measure variation of a rotating surface, the D.C. signal, which will be modulated by the variation is connected directly to the amplifier. The temperature compensation circuit includes a pair of parallel resonant circuits 56, 57 for blocking the A.C. output and the compensating signal is added by lines 27, 28 to the signal across the D.C. diagonal of rectifier 20. The D.C. signal from bridge 20 is applied to bias a rectifier 87 in a rectifier network in the output circuit of an oscillator 82 to determine the amplitude of half cycles fed to amplifier 35. The probe 16 comprises a coil 14 of silver wire set in a plastic tip 44 extending from a cylindrical casing 43. The invention may be applied to monitoring the blades of a rotor, or to monitoring ballbearings as they are passed individually along an insulating conduit. In the latter case the output signal may be used to sort the balls.
