Abstract: In a spinning frame the fiber feed device for each spinning unit is controlled by a separate clutch interposed between a common drive and each unit. The clutches are disengaged during initial start-up and the yarn ends from a previous operation are returned into the spinning chamber. The clutches are then engaged to feed fibers and the yarns are drawn out and taken up on a spool. A breakage detector is provided for each yarn which controls the clutch for each respective fiber feed.

Abstract: A novelty yarn having a pronounced variation in linear density is obtained by passing at least one multifilament yarn through a fluid tangling zone and by alternatingly and mechanically tensioning and relaxing the yarn within the tangling zone. This yarn may be impregnated or coated with wax.

Abstract: A method is provided for dynamically timing an apparatus which includes cyclically generating reference and timing pulses. The method also includes counting the number of reference pulse per generating cycle; measuring a first timing fraction between a leading edge of the first timing pulse and a leading edge of the preceding reference pulse; measuring a second timing fraction between a leading edge of the second timing pulse and a leading edge of the preceding reference pulse; counting the number of whole reference pulses between the leading edges of the timing pulses; subtracting the first timing fraction from the count; and adding the second timing fraction to the count and producing a timing measurement.

Abstract: A liquid meter with an enlarged range of indication mechanism for indicating a residual quantity provided with a fuel sender gage fitted with a float working to detect the quantity of liquid. The float has a suitable number of contacts arranged thereon to change the effective resistance values of resistors built in the fuel sender gage as the float lowers with a decrease in the quantity of liquid. The meter ranges are changed over two stages or three stages automatically and the current to a fuel meter connected to the fuel sender gage, comprising an ammeter, is controlled. Changeover of the meter ranges is indicated through a lamp to enable an enlarged indication of the residual quantity to be made.

Abstract: The wrappers of filter cigarettes wherein wrapper portions surrounding the filter mouthpieces have holes for admission of atmospheric air into the column of tobacco smoke are tested during sidewise movement at the periphery of a rotary drum. A first testing device establishes a first pressure differential between the interior and exterior of successive wrappers, and a second testing device establishes a second pressure differential between the interior and exterior of those wrapper portions which surround tobacco as well as a different third pressure differential between those wrapper portions which surround the filter material. An evaluating circuit has two electropneumatic transducers which furnish first and second signals respectively denoting the pressure differential between the interior and exterior of successive wrappers and the pressure differential between the interior and exterior of successive wrapper portions which surround tobacco.

A chamber is provided with walls which are secured to the upper section for movement therewith. The chamber includes upper, lower and intermediate portions disposed in communication. A test chamber base is secured to the lower stationary section to receive the microelectronic package therein. A first piston is provided in the upper chamber portion for moving the upper frame section downwardly for sealing engagement for the lower chamber portion with the test chamber base. A second piston is provided for compressing air in the lower chamber portion to a predetermined value. A readout device communicates into the test chamber to indicate if compressed air in the lower chamber leaks into the micro-electronic package.

Abstract: A liquid level measuring device for a container is disclosed. The liquid level measuring device has an elongated frame with a lower end insertable into the liquid in the container. Mounted on the frame is a buoyant floats. The floats and frame are constructed so that the floats is movable along the frame by the buoyant forces of the liquid in the container. The measuring device has a manually operable means for selectively holding the floats in a fixed position relative to the frame so that the frame and floats can be withdrawn from the liquid and the level of the liquid read by comparing the position of the floats in relationship to scale indicia on the frame. The elongated frame is made of a plurality of telescopically arranged sections so that the frame can be collapsed to a minimum length for storage and, when the device is to be used for measuring, the frame sections are moved to expand the length of the frame to the total length of the device.

Abstract: An interlocked yarn having a plurality of continuous filaments which have substantially no twist and having at spaced intervals along the length thereof at least one of the filaments encircling the other filaments to interlock the filaments together. The method of making the interlocked yarn includes feeding a plurality of continuous filaments into a fluid jet which has a fluid medium passing therethrough in a direction substantially counter to the direction of travel of the filaments. The interlocked filaments are pulled away from the fluid jet at a rate less than the feed rate. This produces an interlocked yarn having some of the filaments encircling the other filaments to provide an interlock at spaced intervals which eliminates the need to twist the bundle of filaments.

Abstract: Disclosed is a plate-like yarn stripper device for use in removing staple fiber yarns from rotatable elements of circular cross-section, such as in the removal of yarn wraps underwound beneath a spindle blade to anchor the yarn threadline in the doffing and donning of cops on a ring spinning frame. The stripper is formed with a central hole defining stripping edges at a surface of the plate, these edges being spaced from the yarn-wound element by a prescribed distance such that when the element is rotated the wound yarn will buffet the edges and be abraded, weakened and cut or otherwise severed in the stripping action. Personnel safety is enhanced in use of the stripper by the absence of peripheral sharp edges, bristles or other abrasive external surfaces.

Abstract: A draw frame device for spinning machines is provided which includes a preassembled auxiliary draw frame stand formed of a hollow longitudinal pipe member having a plurality of supports welded thereto. The supports are configured for holding supporting rods for supporting upper rolls and loading arms, as well as for supporting lower rolls of a draw frame. Adjustable fastening means are provided at each of the respective opposite ends of the longitudinal member for adjustably connecting the preassembled auxiliary draw frame stand to a hollow longitudinal draw frame stand member of a spinning machine.

Abstract: Fluid, such as air, flowing through a duct is sampled by a detector in a chamber by withdrawing a portion of the fluid from the duct by an impact tube which connects the duct to an inlet in the sampling chamber. Several openings in the impact tube extend across the duct and face into the direction of fluid flow in order to obtain a cross-sectional and representative sample of the fluid. To insure that an adequate sample is obtained, one or more venturi tubes are also placed into the direction of the flow path of the fluid and these venturi tubes are connected to the outlet of the sampling chamber to exert a pressure in the chamber which is negative with respect to the chamber inlet from the impact tube.

Means is provided for catching and directing the extracted meat samples to a container situated beneath the sampling drill bits and which moves inward and outward with the carriage as it moves on the support frame.
