Title: Improvements in and relating to tubular pit props, of the collapsable type
IPC: E21D15/18
Filed: 1934-02-28
Abstract: 430,595. Pit-props. EVANS, D. J., 5, Caldy View, Tumble, Llanelly, Carmarthenshire. Feb. 28, 1934, No. 6429. [Class 20 (ii)] Relates to pit-props of the kind comprising a tubular member D containing sand J or the like, an end plunger A slidably arranged in the tube and adapted to compress the sand, and an aperture in the tube for permitting the escape of the sand therefrom. According to the invention, the tube is provided with an indentation E for relieving the pressure on a bolt F which normally closes the aperture. In the construction shown, the bolt has a slot G through which the sand escapes when the bolt is unscrewed as far as is permitted by a split pin K passing therethrough. The plunger A is attached to the upper end of the tube by a chain C, the lower end of the tube being closed by a fixed plug H. The Provisional Specification describes a construction in which the aperture is normally closed by a plate bearing against the inner face of the tube and carrying a screw-threaded shank passing through the aperture. The shank receives externally of the tube, a rectangular washer and a nut for controlling the opening and closing of the aperture. For retaining the sand within the tube during transport, a lid is hinged to the upper end of the prop and is clamped in its sealing position by a bolt and nut device pivotally mounted on the tube.

Class 39 (4). To prevent vibration when they are stacked in the vertical fuel channels of a nuclear reactor, the fuel elements are each equipped at one end with radial support members, at least one of which may be extended against resilient means to make contact with the channel wall when the adjacent fuel elements engage each other in the channel. Figs. 11 and 12 show a cup-shaped attachment for a fuel element, 55, having support members 56, 57, and 58, of which 56 has a bore 59 carrying arm 60, shoe 61 and spring 62. As the conical end of an upper fuel element engages in the cup, arm 60 is extended until shoe 61 reaches a wall and fixes the element's position. Raising the upper fuel elements causes the arm to retract and frees the fuel element for subsequent removal. Fig. 13 (not shown) shows an embodiment where all three arms of the fitting are radially extendable against the action of a circular clip. The Provisional Specifications also describe several other arrangements wherein support members are extended radially by the weight of a superimposed element, but not against resilient means. The first Provisional Specification refers to Specification 930,663 and the third Provisional Specification to Specification 930,662. Specifications 875,462 and 901,171 also are referred to.

Abstract: 1515092 Well-logging SCHLUMBERGER Ltd 10 Feb 1977 [25 Feb 1976] 07388/76 Heading G1A A method of determining clay in formations traversed by a borehole comprises: producing, at different depths, four magnitudes representing respectively the total natural 7-radiation and that of three constituent materials; determining reference values of the magnitudes in selected zones of the formations; and combining, at each depth of a zone, at least two of the magnitudes in accordance with a function determined from the reference values to obtain a corrected measure of the clay content. Radiation, measured at five energy levels, is analyzed to determine activities G, T, U, K due respectively to the total material and to thorium, uranium and potassium. The activity at any depth in the borehole is calculated as the average at e.g. seven adjacent depths spaced 15 cm. apart, of which the selected depth is the centre. First and second reference values may comprise respectively statistical maxima Gmax ..... Kmax and minima Gmin..... Kmin determined for a zone of pure clay. Third reference values may comprise average values Gcal ...... Kcal determined for a zone known to contain disturbing materials e.g. mica rich in K, or organic material rich in U. To determine the concentration of clay in the presence of excessive K, two approximations are first calculated using only T and U: These approximations are then combined in various proportions A, (1-A) to give: H1 = Vcl(T-U) = A Vcl(T) + (1-A) Vcl(U), until a value of A is found for which values of H1 calculated at the various depths in the zone have the least statistical variation. A similar calculation may be performed on values of G and K, to find coefficients B, (1-B) for which values of Vcl (K-G) have the least statistical deviation from corresponding values Vcl(cal) calculated by combining the third reference values Tcal and Ucal with the first and second reference values. Finally Vcl (T-U) and Vcl (K-G) may be combined in proportions C, (1-C) found to give the smallest standard deviation for the combination over the range of depths.
