Abstract: In order to process yarn preliminarily, and to change over yarn precisely at a desired knitting position, the yarn fed to a flat knitting machine is processed by a yarn processing device. To change over the yarn at a changeover position of knitted fabric, it is necessary to actuate the yarn processing device preliminarily at an actuating position C. A controller calculates the actuating position from a set value in a setting circuit and pattern information from a memory. When an encoder detects that a position of feeding the yarn to a knitting needle has reached the actuating position, the yarn processing device is actuated. The length of the yarn from a yarn processing position to the actuating position is nearly equal to the sum of a knitting loop length from the actuating position to the changeover position.

On the basis of this examination the decision is taken whether a container is acceptably or unacceptably contamined.

Abstract: A sealing element for use in the testing of cigarettes or other rod-shaped articles of the tobacco processing industry has an elastic tubular body with an end portion having an axially movable end wall and an annular lip extending beyond the external surface of the end wall.

Abstract: A sealing element for the end portions of cigarettes or other rod-shaped articles of the tobacco processing industry has an elastic tubular body defining a longitudinally extending passage for the flow of air or another testing fluid from one end of an article being tested or in the opposite direction. The end face of the article being tested is engaged by a deformable membrane at one end of the passage, and such membrane has a central opening for the flow of testing fluid from or into an enlarged chamber between the membrane and an internal fluid deflecting baffle of the tubular body. The baffle causes the testing fluid to flow in the chamber radially inwardly toward or radially outwardly from the opening in the membrane and thus prevents the accumulation of tobacco particles and/or particles of filter material for tobacco smoke in the chamber. The stream of testing fluid in the major portion of the passage flows in the axial direction of the article being tested.

The arrangement permits a reversible displacement of the mass 36 relative to the support frame 8 in the perpendicular plane during a shock without acting upon the transducer 20, and a positioning of the mass 36 relative to the support frame 8 in the absence of the shock.

Abstract: Small changes in material properties of a work piece are detected by measuring small changes in elastic wave velocity and attenuation within a work piece. Active, repeatable source generate coda wave responses from a work piece, where the coda wave responses are temporally displaced. By analyzing progressive relative phase and amplitude changes between the coda wave responses as a function of elapsed time, accurate determinations of velocity and attenuation changes are made. Thus, a small change in velocity occurring within a sample region during the time periods between excitation origin times (herein called "doublets") will produce a relative delay that changes with elapsed time over some portion of the scattered waves. This trend of changing delay is easier to detect than an isolated delay based on a single arrival and provides a direct measure of elastic wave velocity changes arising from changed material properties of the work piece.

Abstract: Method and apparatus (1) for measuring the mass flow rate of solids suspended in a gas stream (2) flowing along a pipe (3). Two ultrasonic transducers (4, 5) are mounted in short side arms (6, 7) extending from the pipe. The transducers are arranged such that signals are transmitted from one to the other through the gas stream at an angle .THETA., usually about 45.degree.. The received signals in both transducers are received by apparatus (8) and amplified. The invention allows determination of: the mean times for the ultrasonic pulses to travel from one transducer (4) to another (5) and vice-versa; the mean peak amplitude of received pulses; and, the standard deviation or spread of these parameters. The mean times taken for the ultrasonic signals to travel between the transducers are used to determine the gas flow velocity, and the mean peak amplitudes for calculating the solids loading. From these the mass flow rate is derived.

Abstract: A Coriolis effect mass flow meter having a brace bar of improved flexibility which reduces the stress concentration in a brace bar as well as in areas of meter's flow tubes proximate the brace bar and flow tubes of the flow meter. A brace bar means is disclosed that has a void in an area between its holes that receive the flow tubes. This void increases the flexibility of the brace bar and shifts the concentration of operational and manufacturing induced stresses away from the braze joints between the brace bar and the flow tubes. The stresses are reduced and shifted away from the flow tubes to an area within the brace bar that is less critical to the overall life and reliability of the flow tubes. Meter sensitivity is improved due to enhanced flexibility of the present invention's brace bar in response to the motion induced by the Coriolis effect.
