Abstract: A process for preparing an oil-in-water emulsion is provided, which process comprises mixing and heating a water-insoluble organomodified polysiloxane oil, an organomodified silicone emulsifier, water and an alkaline metal salt above the cloud point of the emulsifier under agitated conditions and cooling the resulting mixture below the cloud point.

Abstract: An infant car bed for a vehicle is provided which is particularly suitable for the transport of premature or physically disabled infants. The car bed includes an "L" shaped base member adapted to hold an apnea monitor and secured by a vehicle seat belt on a forward facing or rearward facing seat such that the base of the "L" shaped base member rests upon the seat and the vertical leg portion of the "L" shaped base member is proximate the back of the seat. A bed member having a webbed top cover is povitally secured to the upper portion of the vertical leg portion of the base member at a point above the center of gravity of the bed member.

Abstract: A torque converter has a front cover having grooves or depressions integrally formed therein which operate to increase oil flow in the torque converter and hence lubrication and cooling thereof.

Abstract: A leg holding and positioning device for use in surgical operative procedures comprising a housing (10) which is adapted for attachment to the rail (12) of an operating table (not shown) by means of a member (11) and a clamp (13) the housing having projecting from it a shaft (14) which is connected to a viscous damper or other device within the casing (10) to control rotation of the shaft (14), such device being associated with the control knob (18) whereby the shaft may be fixed in any one of a number of rotated positions. A member (25) is attached to one end of the shaft (14) and in use lies alongside the operative leg of a person on the operating table, the leg being secured to the member (25) by means of the bracket (32) and straps (35) and (36).

Abstract: The invention is a system of flow control devices which result in reduced skin friction on aerodynamic and hydrodynamic surfaces. The devices cause a breakup of large-scale disturbances in the boundary layer of the flow field. Referring to FIGS. 1 and 2, the riblet device 10 acts to reduce disturbances near the boundary layer wall by the use of longitudinal striations forming vee-shaped grooves. These grooves are dimensional on the order of the wall vortices and turbulent burst dimensions 31 depicted in FIG. 3. The large-eddy breakup device 41, depicted in FIGS. 4 and 5, is a small strip or airfoil which is suspended in the upper region of the boundary layer. Various physical mechanisms cause a disruption of the large-scale vortices. The combination of the devices of this invention result in a substantial reduction in skin friction drag.
