Abstract: A plastic closure for a container mouth is provided with a flow regulator for selectively controlling the flow of contents during dispensing. The flow regulator includes at least two parts which can be moved relative to each other. Each part has at least one dispensing orifice. The parts are constructed such that respective orifices can be aligned at least partially with respect to each other and with respect to the container mouth. The degree of overlap between the respective orifices defines a common dispensing area to control the flow rate during contents dispensing.

Abstract: A dialyzing machine is provided with a cartridge holder to which a filter cartridge (11) or a dialyzer cartridge can be fastened. The cartridge holder (25) comprises a holding element (35) retaining the cartridge (11) and a clamping element (36) which is movable relatively to the holding element and radially to the inserted cartridge. The clamping element can be moved from an open position into a closed position. It comprises two connecting members (41,42) cooperating with the lateral connecting studs (26,27) of the cartridge, the connecting members (41,42) sealingly engaging with the two connecting studs (26,27) of the cartridge when the clamping element (36) is moved into the closed position. In this way a connection with the two connecting studs of the cartridge is produced by simply attaching the cartridge to the cartridge holder. It is no longer necessary to individually connect hoses to the connecting studs.

Abstract: The invention relates to a method of determining the optical quality of and for detecting faults in flat glass, especially float glass, or other optically transparent materials, a video camera (1) being arranged to monitor an illuminating device (3) either through a glass (2) or by observing the reflection thereof on the glass or material, the focus being on the glass (2) and the material, respectively, and the video camera (1) generating signals in dependence on the quality of the glass (2), with these signals being evaluated, wherein an illuminating device (3) is used whose color and/or intensity is changed in a defined manner, the observation spot (6) of the video camera (1) in the faultless condition of the glass (2) is located substantially in the middle of the illuminating device (3), the illuminating device (3) has assigned thereto two video signals U1,U2, and a change of intensity of the video signals U1,U2 is used for evaluating the quality of the glass (2).

Abstract: A surgical instrument is provided for performing surgery to relieve the symptoms of carpal tunnel syndrome. The surgical instrument includes a pair of pivotally connected legs with each leg including a handle portion and a blade portion with the blade portions terminating in a nose. The nose is inserted through an incision in the wrist area and progressively “worked” into an area between the transverse carpal ligament. The surgical instrument is rotated approximately 90 degrees and the handle portions are then squeezed to spread the blade portions to create a surgical area fully exposing the transverse carpal ligament. One of the blade portions carries illuminating means for illuminating the surgical area or arena to assure that only the transverse carpal ligament is severed to prevent damage to the median nerve, tendons and the like passing through the carpal tunnel.

Abstract: Apparatus for seaming a container end E to an open end of a container body B, comprises a pad to support the container body, a seaming chuck to support the end E in place on the container body B and cooperating with the pad to hold the container body and end one against the other, and an annular seaming tool having two annular seaming profiles on its inner surface which surrounds the end for progressively folding peripheral portions of the container body and end together to form a seam. The annular seaming tool is mounted on a tool holder and means are provided for supporting and driving the tool holder in orbiting motion such that the axis of the seaming tool follows a circular path around the axis of the seaming chuck. The seaming tool is mounted on the apparatus for free rotation about its axis such that when the seaming profile engages the peripheral portions of the container end, it is free to roll around the end to form the seam progressively.

Abstract: A method for molding articles, particularly tires, of different diameters/circumferences including a plurality of pitches defining a mold cavity, the pitches having transverse faces in generally face-to-face abutment in a closed position of the mold cavity, and at least several of the pitches being of different lengthwise sizes. The pitches in the closed position of the mold cavity defining a predetermined mold configuration which includes portions at angles to the length of the article molded in the mold cavity. The mold configuration matches lengthwise across all of the transverse faces irrespective of the location of the pitches relative to each other and irrespective of the number of the pitches. The latter arrangement permits articles, such as new or retread tires, of different lengths but of the generally same predetermined mold configuration to be molded in a single mold.

Abstract: A volute housing is disclosed for use with a centrifugal fan, blower or the like, and includes a housing body defined by opposite spaced sidewalls, a volute peripheral wall disposed between the sidewalls and defining therewith and with an impeller a volute chamber, and the sidewalls each having a generally minimum radial dimension located at a tongue of the volute chamber which progressively increases to a maximum radial dimension located at a throat of the volute chamber. The sidewalls include first sidewall portions which are generally parallel to each other between the tongue and a transition zone 180.degree. therefrom, and second sidewall portions of the sidewalls from the transition zone to the volute throat at approximately 360.degree. are in diverging relationship in a direction away from the transition zone whereby fluid/air flowing through the housing body expands progressively axially outwardly as it flows between and along the second sidewall portions.
