Title: Method of and apparatus for the determination of spontaneous cross sectional variations in textile materials
IPC: B65H63/06
Filed: 1960-06-08
Abstract: 903,445. Determining physical dimensions. ZELLWEGER Ltd. June 8, 1960 [Aug. 12, 1959], No. 20185/60. Addition to 855,267. Class 37. [Also in Group IX] A method of detecting cross-sectional variation in textile material comprises passing the material successively between the plates of at least three capacitors, the two outer capacitors being connected in one arm of a bridge circuit, the remaining capacitors being connected in an adjacent arm. The capacitor electrodes 2, 3, 4, 5 are preferably dimensioned relative to the mean staple length of the material under test so that cross-sectional variations in the form of socalled stretch waves having a relatively long wavelength are not detected but unwanted short defects result in an unbalancing of the bridge from which a signal can be provided to operate a severing device to remove the defect. Fig. 1 shows a bridge circuit having inductive ratio arms 7<SP>1</SP>, 711 and having the outer capacitors comprising plates 2, 5, 4 connected in the upper left hand arm and the central capacitor comprising plates 3, 2 in the lower left-hand arm. The bridge is normally operated unbalanced by adjustment of capacitor 9. The output is rectified at 13 and the residual D.C. component blocked by capacitor 17. Fig. 2 shows a similar bridge comprising capacitive ratio arms 14<SP>1</SP>, 14<SP>11</SP>, the output being rectified at 25, 26 and 27, 28 before being combined in resistors 16<SP>1</SP>, 16<SP>11</SP>. Fig. 4 shows a modification in which the central plate is split at 31<SP>1</SP>, 31<SP>11</SP> so as to provide passage for a severing device 21 operated magnetically when the output of the bridge corresponds to an unwanted defect. Device 21 may act as a clamp which holds the yarn until it is broken by the tension of the pull-off device. The Specification includes ranges of dimensions of electrodes 3, 4, 5 and separation of electrodes 4, 5 for wool and cotton.

Abstract: 571,378. Percussive tools. MOSS, E. W. (Ingersoll-Rand Co.). Dec. 8, 1943, No. 20553. [Class 124] [Also in Group XXII] In a fluid - actuatec riveting machine a single valve controls the move ment of the power unit on its supporting frame to apply pressure to the work and then the supply to the power unit tc close the rivet, the valve being automatic ally closed when the riveting is complete. The casing 22 has bolted to it at 24 a yoke 23 supporting the self-contained abutment 26. The percussive power unit 30 of known type is slidable in the casing under pressure applied first to the end 48 of an extension 47 and then to the end 49 of the unit, a packing ring 42 being provided. A spring 43 returns the parts. The snap holder 34 is retained in the unit, by a spring 36 engaging a shoulder 38, in position to receive the impact of a hammer piston 32. Air supplied at 58 passes by a port 59 to the valve chamber containing a poppet valve 50 held on its seat by a spring 56. The end 74 of the valve projects for actuation by the arm 73 on a rocking and sliding rod 69 having a control lever 76. Rocking is opposed by a spring 82 and sliding by a spring 75. The first stage of the opening movement of the valve closes an exhaust port 60<1> and admits pressure via the groove 60 to a port 61 leading to the end 48. Further movement of the valve cuts off the port 66 from a groove 67 leading to exhaust at 68 and connects it to a pressure supply groove 65 supplied through the ports 64 from the interior of the valve which is fed through ports 63. The port 66 supplies pressure to the end 49 of the casing and also via ports 40 to the percussive mechanism. The gradual advance of the unit 30 in the casing during the closing of the rivet causes it to engage the bent-in end 78 of the rod 69 sliding it to release the arm 73 laterally from the end 74 of the valve when the spring 56 closes it and stops the machine.
