Abstract: Method and Apparatus for Leak Testing of Pipe Abstract A method of testing pipe sections at an oil rig floor by means of an internal pipe testing tool and a pressurized gas containing helium in a ratio of helium to a carrier gas of at least about 1:2856 by volume. The gas is pressurized in a hydraulic accumulator remote from the rig floor. The pressurized gas actuates the test tool at substantially the same pressure as is used for testing the pipe section.  A flexible enclosure con-fines the test gas which leaks from the pipe section. The enclosure defines a substantially annular chamber around the area to be tested to confine leakage test gas to prevent its dissipation into the atmosphere.  An aperture is provided in the enclosure to permit a sens-ing probe to be inserted into the annular chamber between the enclosure and the pipe section to sense the presence of test gas.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention is a method of reducing the hydrolyzable chloride content of an epoxidation product, without substantially altering it otherwise.  The method is characterized by comprising the steps of (1) providing a two-phase mixture of (a) an organic phase which is a solution of said product in a solvent having the characteristics of a blend of from 40 to 55 weight percent methylethylketone and from 60 to 45 weight percent toluene, and (b) an aqueous solution of from 1 to 3 equivalents of base per equivalent of hydrolyzable chloride in said product, the amount of water in said solution being such that the base concen-tration therein will not be less than equivalent to weight percent aqueous NaOH after completion of the following step, and (2) intimately intercontacting said phases, at an elevated temperature, until the hydrolyzable chloride content of said product has decreased to a satisfactory extent.         The method considerably reduces the hydrolyzable chloride content of epoxidation products prepared from epichlorohydrins and phenols, aromatic amines and heterocyclic compounds containing >NH groups in the ring.

Abstract: SUMMARY            The formwork element of brick size is intended to form horizontal wall projections on which e.g. an outer clinker masonry can be bricked up. The formwork element comprises an inner wall (10), an outer wall (12) connected therewith via stems (42,44,46) and an outwardly projecting formwork part (14). The cavity of the latter, via one or several breaks (24,26) provided in the outer wall (12),is in communication with the interspace between the latter and the inner wall (10). In order to adjust the load bearing part of the inner wall (10) to the part (28,30,32) of reduced load-bearing capacity of outer wall (12) and to avoid a sloping position of the wall, inner wall (10) at least on the upper side in the area (60,62) opposite break (24,26) of the outer wall (12) is depressed, with the close tongue-grooving engagement (16,20) being maintained. The protruding form-locking part (14), on the bottom side, is formed in a manner rising in oblique upward direction.

Abstract: APPARATUS AND METHOD FOR LOAN CONTROL OF AN ENGINE           ABSTRACT OF THE DISCLOSURE   Apparatus is for controlling load on an engine, particularly a marine engine powering a controllable pitch propeller which serves as an engine loading device. Apparatus cooperates with a circuit having a supply fluid at a constant supply pressure, and a control fluid at a variable control pressure reflecting engine load. The apparatus has a signal receiver to receive a load demand signal from an operator, and a positioner apparatus with a positioner output which cooperates with the loading device of the engine. The positioner apparatus receives the supply and control fluids and has a partition separating the fluids to permit interaction therebetween to control the positioner output. The apparatus has a hydraulic fluid valve to control flow of hydraulic fluid relative to the positioner apparatus, the fluid valve being connected to the positioner output and an output of the signal receiver so as to be responsive to relative positions of both outputs. The apparatus provides a relatively simple system using hydraulic fluid for accurate load control which responds quickly to an engine overload occurrence so as to reduce the load on the engine quickly to reduce or prevent engine damage. Complex electronics are not required, permitting servicing by persons familiar with mechanical/hydraulic systems. Furthermore, the device has a fail-safe system which accommodates a complete hydraulic pressure failure without damage to the components. Also, a manual over ride provision can be incorporated to permit reduction of load manually, without assistance from hydraulic pressure, should hydraulic pressure fail.
