Abstract: 126,847. Ferguson, Pailin, & Co., Ferguson, S., and Pailin, G. June 20, 1918. Switches, quick-make.-The operating-handle a of a switch is connected through a lever d to a collar g slidably mounted on a rod h secured to the bar m carrying the switch rods, the arrangement being such that, on moving the handle to close the switch, the switch contacts are first moved into close proximity to one another and then held while a spring i is compressed by the further movement of the handle, the spring being finally released to close the switch. The spring i is mounted on the rod h between the collar g and a fixed collar j. When the switch is nearly closed, pins k on the collar j engage a catch o carried by a lever n and prevent further movement of the switch while the spring i is being compressed, after which the lever d engages the end p of the lever n, thereby releasing the catch and permitting the spring to close the switch with a quick movement. The lever n may be weighted at p or spring-controlled, and a stop q is provided to limit its movement in the other direction. The invention is particularly applicable to oil switches.

Title: Apparatus for multiphase fluid separation
IPC: B01L3/14
Filed: 1975-03-12
Abstract: 1495571 Centrifugal separation CORNING GLASS WORKS 12 March 1975 [18 March 1974] 10257/75 Heading B2P  In a fluid collection and partitioning apparatus of the type disclosed in Specification 1456035, a member 40, Fig. 2, having a specific gravity greater than that of the gellike material 30 is initially partially submerged within the gel-like material before the fluid sample is introduced into the container. The member 40 is dimensioned to permit the flow of the gel-like material between its outer surface and the inner surface of the container wall, Fig. 4, as during the centrifugation of the container and its contents, the member 40 gradually moves through the gel-like material to initiate and control its flow towards the stoppered end of the container so as to establish a seal at the interface between the separated fluid phases 62 and 64. In its initial position, the member 40 serves as a means for restraining the gel-like material 30 from flowing from its position adjacent the closed bottom end of the container when the evacuated container is being shipped or handled and therefore prevents the material from forming a continuous seal across the container interior at the fluid-phase interface position before, rather than after, the phases of the fluid sample have separated. When treating blood, by causing the gel-like material to flow along the container inner surface, which may be coated with a lubricant, e.g. a polyethylene oxide polymer, to prevent adhesion of blood thereto, the possibilities of rupturing red cells due to collisions between the latter and the gel-like material is reduced. In its final position, the member 40 is forced into contact with the bottom of the container thereby displacing substantially all of the gel-like material along the inner surface of the container wall. As shown in Figs. 2 and 4, the member 40 may be in the form of a hollow cylinder with a spherical closed end adapted to mate with the bottom of the container, and its outer diameter is less than that of the inner diameter of the container. In the form shown in Figs. 10 and 11, ridges 52 are formed on the cylindrical portion of the member 40 and serve to maintain the annular portions of its exterior surface 44, between the ridges, at equal spaced distances from the container wall to ensure even flow of the gel-like material between the member and the container wall. Alternatively, the member 40 may have a conical, wholly spherical or cylindrical, or cubical configuration. It may be made of plastics of approximate specific gravity 1.2 or of glass of approximate specific gravity 2.0. Examples of the gel-like material are given.
