Abstract: A machine is of the type comprising an oscillating movable head with a tool-holding spindle, driven in rotation above a lens-support. The lens-support is borne by a vertically movable spindle which is mounted inside a sleeve, flared out at its upper part to form two bearing surfaces and, the lens-support comprises a ledge which surrounds the part of the sleeve containing the bearing surfaces. The lens-support rests on a head mounted for free rotation in a fixed pivot so that when the spindle is moved upwardly, the lens-support is immobilized in a horizontal position, to deposit the lenses to be polished thereon, or to remove them after the polishing operation. When the spindle is moved downwardly, the lens-support, then at a distance from the bearing surfaces, can oscillate freely during the lens-polishing operation, under the effect of the movable oscillating head.

Abstract: A mower includes a first chassis attachable to a tractor for movement in a work direction, a second chassis having first and second structures connected at a joint extending perpendicular to the work direction, and connecting rods, each having respective ends pivotally connected to the first chassis and to the second structure of the second chassis so as to form with the first and second chassis an upwardly deformable quadrilateral deformable such that the work elements may move to adapt to ground contours. A release safety device normally prevents pivoting of the first structure about the joint but permits pivoting of the first structure about the joint axis when the first structure or the working elements hooks an obstacle during movement of the mower in the work direction. This limits forces applied to the mower.

Abstract: In the liquefaction of natural gas wherein the refrigeration cycle fluid contains natural gas components, and such components are subjected to fractional condensation to obtain different temperature levels of refrigeration, the system is improved by adjusting the C3-C6 content of cycle fluid and the pressure of at least one intermediate pressure stage of the circulation pressure in such a manner that condensate is formed in the corresponding intercooler of said pressure stage. This condensate is then separated and subjected to heat exchange to utilize its refrigeration values and recirculated to the circulation compressor via an expansion valve. In this way, a substantial concentration of heavy hydrocarbons can be utilized to increase the refrigeration capacity of the refrigeration cycle, but said hydrocarbons do not deleteriously affect the lower temperature levels of refrigeration.
