Abstract

Abstract Apparatus 10 for controllably treating a liquid with a liquid treatment substance includes a body having a first portion 14 providing a container-receiving zone 16 and an opening leading into this zone, as well as a second portion 18 having a liquid inlet 22 and a liquid outlet 24 defining a liquid flow path 20 between them, with the zone being in communication with the liquid flow path. The apparatus also includes a container 35 for a liquid treatment substance. The container comprises a cylindrical sleeve 36, an end piece 38 closing off a first end of the cylindrical sleeve, apertures 42 in the sleeve in proximity to the first end, and seal means 45 between the first end of the sleeve and the aperture. The container is movable from an inoperative position in which the seal means seals fluidtightly against the first portion to prevent liquid passing from the flow path into the aperture, to an operative position in which the first end of the sleeve protrudes at least partially into the flow path. The apparatus further includes bias means 50 inside the body for biassing the first end of the sleeve out of the liquid flow path; actuating means 60 for varying the degree to which the first end of the sleeve protrudes into the flow path: and liquid regulating means 26, 28 inside the body for permitting controlled passage of a slip stream of liquid from the flow passage across the seal means into and out of the inside of the sleeve via the apertures in the sleeve, when the container is in its operative position.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 250 words
Apparatus for controllably treating a liquid with a liquid treatment substance, characterized in that itincludes a body having a first portion providing a container-receiving zone and an opening leading into this zone, as well as a second portion having a liquid inlet and a liquid outlet defining a liquid flow path between them, with the zone being in communication with the liquid flow path; a container for a liquid treatment substance, the container comprising a cylindrical sleeve, an end piece closing off a first end of the cylindrical sleeve, at least one aperture in the sleeve in proximity to the first end, and seal means between the first end of the sleeve and the aperture, and being movable from an inoperative position in which the seal means seals fluidtightly against the first portion to prevent liquid passing from the flow path into the aperture, to an operative position in which the first end of the sleeve protrudes at least partially into the flow path; bias means inside the body for biassing the first end of the sleeve out of the liquid flow path; actuating means for varying the degree to which the first end of the sleeve protrudes into the flow path; and liquid regulating means inside the body for permitting controlled passage of a slip stream of liquid from the flow passage across the seal means into and out of the inside of the sleeve via the aperture in the sleeve, when the container is in its operative position.
Claim 2
Dependent Claim 250 words
Apparatus for controllably treating a liquid with a liquid treatment substance, characterized in that itincludes a body having a first portion providing a container-receiving zone and an opening leading into this zone, as well as a second portion having a liquid inlet and a liquid outlet defining a liquid flow path between them, with the zone being in communication with the liquid flow path; a container for a liquid treatment substance, the container comprising a cylindrical sleeve, an end piece closing off a first end of the cylindrical sleeve, at least one aperture in the sleeve in proximity to the first end, and seal means between the first end of the sleeve and the aperture, and being movable from an inoperative position in which the seal means seals fluidtightly against the first portion to prevent liquid passing from the flow path into the aperture, to an operative position in which the first end of the sleeve protrudes at least partially into the flow path; bias means inside the body for biassing the first end of the sleeve out of the liquid flow path; actuating means for varying the degree to which the first end of the sleeve protrudes into the flow path; and liquid regulating means inside the body for permitting controlled passage of a slip stream of liquid from the flow passage across the seal means into and out of the inside of the sleeve via the aperture in the sleeve, when the container is in its operative position.
Claim 3
Dependent Claim 101 words
Apparatus according to Claim 1, characterized in that the liquid inlet is aligned with the liquid outlet so that the liquid flow path is linear, with the zone being of elongate cylindrical form and extending orthogonally to the liquid flow path and being located between the liquid inlet and the liquid outlet, and wherein the liquid regulating means comprises a first skirt-like portion fast with the body and depending beyond the zone into the flow path in proximity to the inlet opening, and a flow restriction means associated with the skirt for permitting the liquid slip stream flow into the container.
Claim 4
Dependent Claim 58 words
Apparatus according to Claim 2, characterized in that it includes a second skirt-like portion, similar to the first skirt-like portion, and also having flow restriction means, in proximity to the outlet opening, so that the skirt-like portions and the sections of the body located between them constitute an extension to the zone which protrudes into the flow path.
Claim 5
Dependent Claim 31 words
Apparatus according to Claim 3, characterized in that the flow restriction means comprise apertures in the skirt-like portions, the apertures being aligned with each other when the apparatus is seen end-on.
Claim 6
Dependent Claim 70 words
Apparatus according to Claim 3, characterized in that the flow restriction means comprises a trough in the inner surface of each of the skirt-like portions so that, when the first end of the container protrudes into the flow path, the seal means is located intermediate the respective ends of the troughs, thereby to permit the slip stream of liquid to pass around the seal means by passing along the troughs.
