Abstract: A controlled replenishing lubrication system provides a desired supply of oil to a rolling element bearing (24) by monitoring the changes in the rolling element ball retainer (20) to shaft (14) speed ratio. This ratio is a function of elastohydrodynamic oil film thickness between rotating elements of the bearing. Changes in the speed ratio are monitored by a sensor (32) and fed to a control system which commands a pump to inject oil into the bearing when the speed ratio varies from a predetermined limit. The rolling elements (18) are moveably mounted for rotation within a retainer or cage (20) in a bearing housing (12). The retainer includes a light reflective indicia (48). A shaft (14) is rotatably connected to rotate the rotatable race (16) of the bearing. The shaft also includes a light reflective indicia (38). The sensor (32) is mounted on or adjacent the bearing for simultaneously emitting light toward the retainer and shaft indicia (48,38) for sensing variations in reflection of the light therefrom and for generating pulses to control the pump

Abstract: The invention relates to a procedure for the fabrication of a metal vessel with an inner coating and a handle and to a welding device for resistance welding with two electrodes, in particular for use in the procedure according to the invention. In the fabrication of internally coated, thin-walled metal vessels, it is not possible to subsequently weld handles or supporting elements to the metal vessel without damaging the coating. Welding on the handles before the coating treatment proves to be disadvantageous, since subsequent cleaning of the outer surface of the vessel is made more difficult. According to the invention, a reinforcing plate (5) is welded to the outer surface of the metal vessel (1) before the inner surface of the latter is coated, onto which reinforcing plate (5) a handle (3) can be welded after the outer surface (4) of the metal vessel (1) has been cleaned, a welding device being used in which the electrodes (6, 6a) are arranged directly next to one another. The invention can generally be used in the fabrication of metal vessels, in particular cooking utensils. <IMAGE>
