Title: Device for visibly ascertaining the position of the weft threads in travelling cloth strips and for controlling weft straightening equipment
IPC: D06H3/12
Filed: 1959-04-20
Abstract: 871,325. Automatic control systems for moving webs. MAHLO, H. April 20, 1959 [April 26, 1958], No. 13449/59. Class 38 (4). [Also in Groups VIII and XL (b)] The lay of the weft threads in a moving fabric is detected by shining light through the fabric to a photo-electric cell formed with an elongated light aperture, the alternating component imparted to the cell output as the threads interrupt the light having a maximum amplitude when the threads lie parallel to the aperture. The width of the cell aperture is made the same as the thickness of a thread or the gap between two adjacent threads. The cell output may control automatic weft straightening apparatus. In one way of carrying out the invention, Fig. 6, two stationary cells 14 and 15 are disposed at equal and opposite angles to the normal weft direction and apply their outputs through amplifiers 16, 17 and rectifiers 19, 20 to a differential circuit 23, 24 controlling a polarized relay 25. With the weft in the normal direction the cell outputs are equal and the relay occupies its neutral position. Skew of the threads in either direction causes operation of the relay in the corresponding direction. Skew and bow of weft threads may be detected, Fig. 7 (not shown), by the use of two detecting arrangements somewhat similar to that shown in Fig. 6, one adjacent each selvedge. The outputs of the two detectors are applied in the same polarity to a first differential circuit so as to produce a response only when the two outputs are of like polarity, so indicating skew, and are applied in relatively reversed polarity to a second differential circuit so as to produce a response only when the two outputs are of different polarity, so indicating bow. A number of detecting arrangements according to the invention suitably inclined to normal weft direction may be disposed across the width of the fabric and may control apparatus to introduce a desired bow to the weft threads when the fabric enters a tentering frame in order that the fabric may leave the frame with straight threads, Fig. 11 (not shown). Automatic control is preferably effected by detectors at both the input and output of the frame. An alarm system is provided, Fig. 12 (not shown), when weft distortion exceeds the limit that may be converted automatically. The Specification discusses a number of auxiliary features including automatic gain control of the photo-electric cell amplifiers, Fig. 10 (not shown), an arrangement for translating the detector output into impulses the repetition frequency of which increases with the amplitude of detector signal, Fig. 8 (not shown), and the use of electrical bias to obtain an effect equivalent to varying the inclination of the detecting cells.

Title: Improvements in Artificial Legs.
Inventor: THOMAS HENRY HARRIS
IPC: A61F2/60
Filed: 1918-08-23
Abstract: 131,458. Thomas, H. H., and Hobbs, E. W. Aug. 23, 1918. No Patent granted (Seading fee not paid). Limbs, artificial.-In a leg with a hinged foot and knee joint, a knee lock automatically becomes operative when the foot is turned about its hinge in either direction as by pressure upon either the heel or toe. A sleeve 5, Fig. 1, slides on the shin tube g, and is connected to the bucket irons d and the thigh above the knee pivot f by links g. The links are pivoted at 10 to the bucket irons, and the lower pivot 8 is slidable in a slot 7 of a bracket 6 on the sleeve 5. In the outward position of the links 9, as shown, the knee joint is locked as any tension or strain on the links will cause the sleeve 5 to tilt and jam, but when the links are closed up to the shin tube the sleeve 5 can slide freely on the shin tube. A spring 12 prevents any tendency of the sleeve to tilt when moving on the shin tube. The links 9 are positioned in accordance with the angular movement of the foot about the pivot o by a rod 13 which extends between two freely rotatable collars 3, 14 and engages a forked lug on the rotatable sleeve 16, Fig. 3, which is connected to the links 9 by a ball and socket joint 17 and a link 21. The collar 3 is rotated by pins 2, Fig. 2, on the pivot o of the foot, and one or other of the pins move the collar 3 when the foot is bent. The parts are returned to normal inoperative position by a spring 18. In the operative position of the links 9 a cross-bar 16 between the links 9 rests on a projecting lug 20 of the bracket 6, and in the inoperative position another cross bar 22 rests on the bracket 6 thereby relieving the pin 8 of strain. The angular movement of the knee joint is limited by a bar e between the bucket irons d which in the extended position of the leg engages the shin tube g below the knee joint f and in the fully bent position engages the bent part h of the shin tube. Cords or similar devices may be used to control the bending of the knee as described in Specification 108,143. The shin tube g has fixed to it a metal plate t formed in one with the socket u within which the shin tube is fixed, and the angular motion of the foot is facilitated by resilient members w, x as described in Specification 107,997.
