Title: Loop-taker and bobbin-case devices for sewing machines
IPC: D05B57/14
Filed: 1936-01-25
Abstract: 452,001. Sewing - machines. FAIRWEATHER, W. C., 65, Chancery Lane, London.-(Singer Manufacturing Co. ; Elizabeth, New Jersey, U.S.A.) Jan. 25, 1936, No. 2403. [Class 112] A lock-stitch sewing- machine having a rotary hook surrounding a bobbin case which is held against rotation by a detent 21 engaging a shoulder on the spool case, has means for removing all slack from the thread loop before it leaves a loop-controlling tail on the hook in such a way that it exerts a tangential pull on the bobbin case and opens an escape gap for the loop between the detent and shoulder to avoid pinching the thread. The loop taker and hook shown are similar to those described in Specifications 12609/11, [Class 112], and 421,957. The bobbin case has a rib 15 working in a groove in the rotary hook which has a loop-taking beak 12<1> and a loop controlling tail 13 onto which the cast-off loop is lifted by a flange 19 on the bobbin case. A gap is formed in the rib 15 so as to leave a radial shoulder 18 beyond the transverse plane of the needle and a notch 23 is formed in the flange 19, and as the loop is tightened by the rising needle the reaction on the shoulder 18 opens a gap 33 between the spool case and the detent 21 so as to permit the escape of the loop. The bobbin is placed in a separable part 24, Fig. 16, of the case which has a threading slot 26 leading to a second slot 28 beneath a tensioning-spring 30.
Patent GB-524224-A (GB)
Title: Improvements in signal transmission systems
IPC: H03F1/36
Filed: 1939-01-24
Abstract: 524,224. Repeating systems. STANDARD TELEPHONES & CABLES, Ltd., HODGSON, K. G., and ROCHE, A. H. Jan. 24, 1939, No. 2479. Drawings to Specification. [Class 40 (iv)] In a multi-channel carrier system with common amplifiers, the interference due to Johnson noise (E.M.F. of thermal agitation) or to valve noise if that should predominate sets a limiting lower level for the signal currents, while the interference due to intermodulation sets a limiting upper level, so that the maximum attenuation the line may have for satisfactory operation is fixed. As the number of line sections is increased, the Johnson noise increases and therefore the maximum permissible line section attenuation is reduced. At the same time the intermodulation interference tends to increase with the number of repeaters. According to the invention, negative feedback amplifiers are employed, and the reduction of repeater gain necessitated by the cumulative effect of Johnson noise is obtained by an increase of feedback, so that the intermodulation effect in the individual amplifiers is reduced and the total intermodulation interference remains the same as the number of repeaters increases. As the length of the line is increased, the repeater spacing is reduced, and the signal level at the repeater output remains the same. The optimum conditions occur when the signal level is such that the interference due to Johnson noise is equal to that due to intermodulation.
