Title: Apparatus and method for treating water with ozone
Inventor: SHAW DONALD
IPC: C02F1/78
Filed: 1993-04-20
Granted: 1998-09-15
Abstract: An apparatus and method for treating water with ozone. An outer conduit forms a continuous, vertical loop. A pump is connected to the bottom of the loop and pumps water about the loop from the bottom towards a first side. An opening admits ozone into the outer conduit. There is an outlet for gases near the top of the loop. An inner conduit within the outer conduit is spaced - apart therefrom to form a passageway for water therebetween. The inner conduit has an inlet between the opening for ozone and the outlet for gases and an outlet within the outer conduit on the second side of the loop. Some of the water is diverted into the inlet of the inner conduit. A flow of water at reduced linear velocity is permitted through the passageway into the outer conduit. Ozone released at the outlet of the inner conduit flows upwardly through the outer conduit in counterflow to the water therein to increase the amount of ozone dissolved in the water.

Abstract: A hydraulic ball coupling assembly (1) comprises an inner hub (2) and an outer hub (3) disposed for relative coaxial rotational engagement. The inner hub (2) includes a continuous sinuate recessed track (4) extending circumferentially around the cylindrical outer surface (5). The outer hub (3) includes a plurality of uniformly spaced axially extending grooves (6) on the inner cylindrical surface (7). The grooves (6) extend in a direction substantially normal to the general effective direction of the sinuate track (4). A slider (10) is reciprocally disposed within each groove (6) and located in the intersecting region (11) of the sinuate track (4) and the respective groove (6) such that relative rotation of the inner and outer hubs (2, 3) causes each slider (10) to oscillate axially within its respective groove (6) while traversing the track (4). The grooves (6) and track (4) contain a hydraulic fluid of suitable viscosity to provide fluid resistance to the oscillation of the sliders (10) and thereby permit transmission of torque between the inner and outer hubs (2, 3).

Patent CA-2125352-C (CA)
Inventor: VON HOLDT JOHN W SR
IPC: B65D41/18

Granted: 1999-08-03
Abstract: A snap-on  flexible  lid  for  a  container comprises a flat lid face and an annular, peripheral flange extending normally of the lid face to enclose and grip an annular lip of a container.  The term "annular" is intended to include all closed loops,  for example those of rectangular containers.  The flange comprises spaced panels angled inwardly from the remainder of the flange to engage the underside of the container lip.          This promotes retention of the lid on the container and permits a container where the flange is essentially free of circumferential tear lines, avoiding problems of lid pop-off, and undesired tearing of the circumferential tear lines in the event the container is dropped.  The angled panels  are  defined  between pairs  of  cutting apertures  to permit  the  separation  of  the  sections defining the panels by a pair of vertical cuts,  for opening of the container.

Title: Resilient plastic web exhibiting reduced skin contact area and enhanced fluid transfer properties
Inventor: GOODMAN WILLIAM HARRY JR
IPC: A61F13/15
Filed: 1992-12-21
Granted: 1998-09-01
Abstract: A resilient three-dimensional plastic web exhibiting reduced skin contact area and a fiber-like appearance and tactile impression. The web has a multiplicity of apertures therein, each being defined by a multiplicity of intersecting fiber-like elements interconnected to one another in the plane of the first surface of the web. Each of the fiber-like elements exhibits a substantially uniform generally upwardly concave shaped cross section along its length. The cross section comprises at least one pair of convergent substantially linear portions which intersect one another to form a vertex in the plane of the first surface of the web. This vertex reduces the skin contact area of the web providing a more comfortable feel for the user when the web is employed as a wearer contacting topsheet in a disposable absorbent bandage. Furthermore, the web provides a substantially non-glossy visible surface as there is almost no substantially planar portion in its uppermost surface to reflect incident light to the viewer's eye. The pattern of intersecting vertices in the first surface of the web substantially eliminates pooling of fluids on the first surface of the web, since there is almost no substantially planar portion on which the fluids may pool. This further contributes to the web's clean and dry appearance in use as well as more rapid fluid transport into the underlying absorbent core.

Abstract: A method is described for the making of a high definition tooth mold which includes the steps of scanning the surface of a model of a tooth, processing the data in a CAD/CAM computer, and using the processed data to fabricate a tooth mold. The scanning step involves subjecting a rotating tooth model to radiant energy, receiving and translating reflections of the radiant energy into electronic signals, and digitizing the signals into data of the three-dimensional surface locations of the tooth model.      The processing step involves translating the data, editing the data, creating a three-dimensional surface pattern of the tooth model, evaluating the surface pattern and creating a new three-dimensional surface pattern until an acceptable high definition surface pattern is achieved by adding supplemental data or repeating the scanning step. Finally, creating a tooth path program used in the fabricating step to mill a tooth mold.
