Abstract: The invention relates to a method and device for cutting a bundle of tubes containing a nuclear fuel into pieces having a preset length so that the fuel can be dissolved in a suitable solution.The bundle of tubes is introduced into a guide tube in a shearing machine and is clamped by two side clamps within the tube so as to limit the width of the bundle to the diameter of one tube of the bundle. The side clamps subject the bundle to a sideways thrust so that the tubes in the bundle are maintained contiguous without any excessive curvature. The bundle of tubes is then submitted to a cutting operation at right angles to its major dimension and after the blade has been returned to its inoperative position a safety plate is positioned near the cut section at a distance slightly greater than the forward movement of the bundle between two successive cutting operations. The side clamps are then withdrawn by a limited amount so that the resilience of the tubes causes them to remain in contact with the clamps.

C. to 130.degree. C. for a period which varies according to the temperature but which is not less than 10 minutes.

Abstract: A disc filter chute liner for being inserted in the passageway formed in a cake discharge chute of a disc filter and for being interposed between the cake discharge chute and cake passing therethrough and for preventing the cake from adhering to the cake discharge filter, the disc filter chute liner being provided with smooth and slick internal surfaces with respect to the cake whereby the cake passing through the liner will not adhere to the smooth and slick surfaces and thereby in turn will not adhere to the cake discharge chute.

Abstract: A turbine rotor having twisted blades, are, in the vicinity of their radiy outer portions integrally connected with each other to prevent any rotation in either direction of one blade in relation to its neighboring blades. The blades are prestressed during assembly by being un-twisted through an angle which is less than or equal to and in the same direction as the angle through which said blades would be un-twisted during rotation if they were free to rotate in relation to each other.

Abstract: A rennet-like milk-curdling enzyme is obtained from the stomach tissue of poultry by immersing the tissue in an aqueous saline solution with a pH-value below 4, and thereafter separating out undissolved materials to leave a solution containing the enzyme.

Abstract: A probe safety coupling device adapted for use in a cooking system, such as in the deep fat frying of French fries, fish, chicken and the like, wherein the cooking is to be controlled by an electrical control unit responsive to the temperature of a predetermined portion of the cooking medium as sensed by a probe assembly containing a temperature-sensitive element at one end and delivering electrical signals to the control unit through a flexible conduit at the other end. The probe assembly is attached to the control unit with good electrical contact and with lessened risk of probe breakage by means of a safety coupling device which includes a first electrical connector fixedly secured to the timing computer and joined to a length of flexible conduit terminating in a second electrical connector.

Abstract: An electrolysis apparatus formed by a stack of cells which are held together by two end-plates connected by tie-rods, wherein a system comprising two kinds of elements provides, firstly, electrical insulation between pairs of adjoining rings and secondly a seal to prevent the electrolyte from escaping to the exterior.
