  • Patent number: 4550577
    Abstract: To insure gentle latch operation, and particularly gentle opening of the latch, the last-knitted loop (36) is constrained to move in the same direction as the needles (2) by controlling movement of sinkers (7) in the same direction as the needles, at a speed slower than needle speed during the raising phase of the needles (FIGS. 5, 6), so that initial movement of the latch occurs slowly and not abruptly to permit faster knitting speeds by reducing stresses on the latch. Conversely, during closing movement of the latch (FIGS. 9, 10), initially, the loop and the needle are lowered simultaneously, the lowering speed of the loop, controlled by the sinker (7) being slower than the lowering speed of the needle. Cast-off can be improved by rapidly controlling the loop by suitable sinker movement (FIGS. 11, 12).

  • Patent number: 4550586
    Abstract: The device employs a number of detectors (1) mounted at the level of the upper surface of the die (2) and a numerical control system (5). The purpose of the detectors is to signal to the numerical control the moment that the part b of the sheet begins to rise. The device allows the automatic determination of the thickness of the sheet in the area where the bend is to be located, during the course of the forming operation. The thickness of the sheet is then used by a numerical control system to correct the travel of the tool, without interrupting the forming cycle, in such a way as to obtain with high precision the required bend angle.

  • Patent number: 4550591
    Abstract: An apparatus for monitoring particulate matter in the fluid comprises a filter means (28) through which fluid is arranged to flow. A pressure sensing means (46) senses the fluid pressure difference across the filter means and produces a pressure signal indicative of the magnitude of the pressure difference. A processing means (49) receives the pressure signal and evaluates therefrom the rate of change of the magnitude of the pressure difference in order to give an indication of particulate matter levels in the fluid. In this way on line monitoring of the debris generation in, for example an oil system, can be effected so that abnormal increases in debris can be detected and long term trends in the build-up of debris can be observed. A particular form of filter medium is also disclosed wherein the filter mean can be transported so that a filter record can be maintained and systematic X-ray analysis of the filter record can be effected.

  • Patent number: 4550592
    Abstract: A bridge type pneumatic circuit, for pneumatic gauging, having an inlet and two branch passageways through which flow of compressed air from an inlet to an outlet of each branch passageway is controlled by an adjustable orifice. One of the outlets is connected to the nozzle, or nozzles, of an air gauge head, such that the pressure of the air flowing past the corresponding adjustable orifice varies as a function of the distance separating the nozzle from the surface, while the other branch passageway is vented to atmosphere through a calibrated orifice to establish a zero reference. The differential pressure between the passageways downstream of the adjustable control orifices is monitored by a differential pressure transducer to provide a control signal to a measurement display instrument. In the alternative, the outlet of the second branch passageway is also connected to the nozzle, or nozzles of an air gauge head, to effectuate differential measurements.
