Abstract: 1,188,764. Sewing machines. MEFINA S.A. 19 Nov., 1968 [22 Dec., 1967], No. 54827/68. Heading D1G. A thread take-up arrangement comprises an oscillatory lever having one end adapted to draw the thread upwards after the formation of a stitch, and an elongated cover covering said one end over its entire movement and having a substantially U-shaped cross-section with two slits being oppositely located in lateral walls, characterised in that the slits join in the upper end of the cover to permit the thread to be placed in the slits and to freely contact an upper surface of said lever end. As shown, the crank 10, carrying a crank pin actuating the pitman 5 driving the needle bar 7, has a second crank pin 11 to which is pivoted a sleeve 37 slidably receiving a rod 38 rigid with the thread take-up lever 12. One end of the latter is pivoted at 39 to the machine frame, and the other end is hook-shaped to receive the thread, and oscillates within a cover 30 formed at its opposed sides with thread-passing slits 31 which merge into an upper slit (32) partly closed by a tongue 36. The lever end is perforated to receive either a plastics pin or a felt plug, the ends of which engage the opposed surfaces of cover 30 to guide the lever therein and to prevent passage of the thread 18 beneath said end. The latter may, alternatively, be provided with a thread-guiding eyelet. In a modification, the inner end of lever 12 is pivoted on pin 11, and lever 12 is pivoted intermediately to a swinging link.

Abstract: 1453941 Automatic control of feedrate H CUTLER 18 Dec 1973 [29 Dec 1972]  58578/73 Heading G3N In a two, or three dimensional path control system in which axes command pulses xCP, yCP, zCP are provided to drives 6, 8, 10, a velocity control system 14 includes counters (110, 120, 130), Fig. 3 (not shown) accumulating the axes command pulses, and a feedrate command register (100), accumulating feedrate command pulses (fCP). For each occurrence of an axis pulse, the content of the corresponding axis register is added to an error register, each feedrate command pulse causing subtraction of the content of the feedrate command register from the error register, feed pulses FP, for one or other of the axes, being provided whenever, after a change in the error register content, the resultant content is negative. A programmed path is thus followed at the commanded feedrate. A desired programmed motion, for linear, circular, hyperbolic or parabolic interpolation, is fed to path generator 12, feedrate data, in either distance per minute, or distance per revolution form for multiplication by a spindle speed signal from digital tachometer 32 being fed to control system 14. The operator's feedrate override 26 acts to control the frequency of a pulse generator (44) Fig. 2 (not shown), whose output is multiplied by the programmed inches/min feedrate to provide the pulses (fCP), or, alternatively, in the inches/revolution mode, the output of multiplier (46) is sampled and supplied to register (80) for multiplication by the spindle tacho output to provide the pulses (fCP). The program data may be on magnetic tape, or be supplied by a MOS memory. The description includes tables showing how the desired feedrate and path are achieved. A suitable path generator is disclosed in Specification 1453942. When register (100) reaches its capacity limit, a signal on leads (182, 184) clears all the registers. Alternatively, the capacity limits of all registers can be monitored, all registers being cleared when any one of them reaches its capacity. All registers are cleared at the start of a new path.

Abstract: 1431541 Photo-electric measuring method ENGLISH CLAYS LOVERING POCHIN & CO Ltd 22 March 1973 [22 Dec 1971] 59798/71 Heading G1A The settling rate of suspended solid matter in a sewage liquid is determined by introducing thoroughly mixed sewage liquid into a container, stopping the flow of liquid into the container and allowing the solid matter to settle, and measuring photo-electrically either the time taken for the interface formed between the settling solid matter and the supernatant liquid to descend a known vertical distance after the flow has been stopped or the distance descended by the interface after a predetermined period of time has elapsed from the cessation of flow. In the first alternative, the flow is stopped when the liquid reaches a first level and a horizontal beam of light is projected into the liquid at a second level, a known distance below the first level, which beam is transmitted or reflected to at least one photo-electric device, the passing of the interface through the second level producing a change in output of the photo-electric device. The time taken for the interface to fall from the first level or a known third level between the first and second levels, to the second level is measured. Alternatively, a light source and photo-electric detector are arranged above the liquid level in the container so that light reflected from the interface produces a change in output of the detector when it falls to the second level. In both embodiments, the passage of the interface through the upper level is measured photo-electrically. In the second alternative, a plurality of sources and detectors are arranged vertically relative to the container so that the distance descended by the interface may be determined. In one embodiment of the apparatus, Figs. 2a, 2b and 3 (not shown), the container is cylindrical with its axis horizontal, the container being provided with an inlet, an outlet and an overflow. Light is projected into the container through a window, reflected light being transmitted through the same window to a photo-cell. A parameter of a continuous process for treating sewage liquid is controlled by measuring, by one of the methods described, the settling rates of a series of samples of sewage liquid of known and different solid concentrations, monitoring continuously or intermittently the solids concentration of the sewage liquid during its treatment by measuring the settling rate by one of the methods described, comparing the measurements obtained with the known values, and adjusting the parameter, e.g. aeration, accordingly.
