Abstract: 1,214,727. Weft stop motion in travelling wave loom. RUTI MACHINERY WORKS Ltd. 23 Sept., 1968 [21 Sept., 1967]; No. 45197/68. Heading DIE. A weft stop motion detector for a travelling wave loom consists of a frame 37, 38, 40 pivoted at 36; whilst a shuttle 18 is passing under either limb 37, 38 it holds the frame away from the weft, but when the shuttle is between the limbs, the limb 37 rests on the weft if present, or the frame falls on to a contact 41 if weft is absent. In a similar version, the frame is held up for part of the time by the beat-up and shuttle-propelling blades 19. In another form, a photocell senses the weft at the exit end of the shed, the field of view of the cell being blocked by the shuttle until its trailing end emerges from the shed; just before this occurs, switches operated by the shuttle propelling blades energise the photocell circuit, so that, as the weft is selected by the shuttle and drawn into a suction tube, it is detected by the cell.

Abstract: 1,175,479. Measuring thickness of a silt layer, electrically. AMSTERDAMSCHE BALLAST MAATSCHAPPIJ N. V. Sept. 27, 1968 [Sept. 28, 1967], No. 46101/68. Heading G1N. The thickness of an underwater layer of silt is measured by lowering a probe 6 so that a first pressure transducer 7 on the tip of the probe completely penetrates the layer while a second pressure transducer 8 remains above the layer and feeding the outputs from the transducers to the X and Y inputs respectively of an X. Y recorder. The thickness of the silt layer is then deduced from the difference in depth of the probe (as represented by the output of the second transducer) between points on the recording where the first transducer enters the silt and where it reaches the bottom of the silt layer. The probe may be suspended directly from a cable as shown in Fig.1 or may be mounted on a hydraulic jack carried by a frame standing on the silt layer. The second transducer may incorporate a diaphragm. The first transducer may include strain gauges or may comprise a pressure difference gauge responding to the difference in pressure at two closely vertically spaced outlets through which water is fed under pressure from a surface vessel.
