Abstract: A tubular valve for controlling the flow of fluids includes an outer tubular shell having pairs of ports on diametrically opposed surfaces and an inner coaxial transfer tube having pairs of openings which are selectively rotated into or out of alignment with the outer tubular ports. Deformable grommets enclose and seal the space between the outer shell and inner tube and provide lateral tubular extensions projecting through the outer ports for connection to external sources and apparatus. The inner transfer tube, which is rotatable within the grommets, provides communication for fluid flow between inlet and outlet ports and openings. Different fluids may be selectively controlled and supplied through separate outlets.During assembly, each deformable grommet is folded around an insertion device which is inserted into the outer tubular shell and twisted to release the tubular extension which projects laterally from the port.

Abstract: Valve mechanism supplying creme on the tops of a succession of two rows of cookies for sandwiching. The cookies are moved along a sandwiching machine by a conveyor beneath a rotating stencil supplying creme to the cookies, under the control of a one-piece valve assuring a uniform supply of creme on the tops of cookies of each row of cookies to thereafter be sandwiched by other cookies supplied to the cremed cookies as passing along the conveyor. The valve is in the form of a one-piece valve block supported at one end and rotationally adjusted to balance the flow through orifices in a stencil sleeve within which the valve is mounted. The creme enters the stencil sleeve from one end of the tube. The stencil sleeve has an outlet port for each row of cookies, which in turn supplies the creme to annular orifices in a rotating stencil, rotating at the speed of travel of the conveyor and the cookies carried thereby.

Abstract: An enclosure for encapsulating and sealing a splice between two or more underground cables is disclosed. A tubular chamber is provided to receive the splice, and the chamber has a radial access hole for pouring plastic compound into the chamber. The cables to be spliced pass through caps which enclose the ends of the chamber. A rotatable sleeve fits over the center of the chamber. The sleeve has an aperture corresponding to the access hole in the tubular chamber, and an outwardly projecting funnel extending from the aperture. The aperture in the sleeve can be aligned with the access hole and liquid plastic compound poured through the funnel into the tubular chamber to surround the splice. When the chamber has been filled with plastic compound, the sleeve can simply be rotated with respect to the chamber and locked to disalign the aperture and the access hole and thereby seal the chamber.

Abstract: A sleeve valve having control of the rate of fluid flow therethrough by rotation of an outer sleeve is disclosed. Fluid flows in through a longitudinal bore in a valve body, then outward through one or more radial apertures extending outward from the longitudinal bore. An O-ring which is mounted eccentrically within a sleeve positioned around the valve body covers the radial aperture to an amount depending upon the angular position of the sleeve with respect to the valve body. The invention encompasses both flow control and metering valves. A linear or other desired relationship between angular position of the sleeve with respect to the valve body versus flow rate of fluid through the valve may be achieved.
