Abstract: 586,289. Conveyers. DENNEHY, W. J. Aug. 11, 194:4, No. 15357. [Class 78 (i)] Apparatus for conveying flexible articles for treatment comprises horizontally disposed and rotatable drums arranged so that one lies in a horizontal plane above the other and with their vertical axes spaced apart so that a portion of the periphery of one drum will, as seen from above, be close to, tangential with or slightly overlapping the periphery of the adjacent drum, and an endless rope belt or the like for each drum which extends partly around the periphery of its drum and between which ropes or the like and the peripheries of the drums the article to be conveyed may be gripped, the rope of the lower drum having a part which lies in the path of the article as it is conveyed by the upper drum, the arrangement being such that, as the article is conveyed by the upper drum, one end of the article is free for treatment and the article is thereafter automatically transferred to the lower drum, the treated portion being gripped between the rope and the periphery of the lower drum while the previously held part is released for treatment. In the embodiment shown, leaves 17 of flax are conveyed through treatment zones by rollers 1, 2 adjustably mounted on shafts 4, 5. The leaves are placed by manual or mechanical means on the roller 1 so that about half of each leaf depends freely from the roller for treatment or processing. During treatment the upper half of the leaf is held against the roller by an endless rope 8 engaging in a groove in the roller. Adjacent the roller 2 the free or treated end of the leaf engages an endless rope 12 passing around this roller and a guide pulley 13. Immediately afterwards the upper portion of the leaf becomes free of the roller 1 and falls over the rope 12 so as to depend from the roller 2 free for treatment. The previously treated portion of the leaf is now held against the roller 2 by the rope 12 and the leaf is fed through a treatment zone to become free again on reaching the pulley 14a. The rollers are rotated in opposite directions by the ropes 8, 12 or by any other means.

Filed: 1962-04-19
Abstract: 947,450. Automatic control of size. HUTTEN-UND BERGWERKE RHEINHAUSER A.G. April 19, 1962 [April 20, 1961], No. 15372/62. Heading G3R. [Also in Division G1] The deviation of the cross-sectional area of a body such as a moving wire having a round or oval section, from some predetermined value is measured by two feelers 1, 2, which each measure divergencies of the section diameter from a desired value at two mutually perpendicular coordinates and the outputs from which are combined and may be used to control cutting tools positioned immediately before its feelers. The Specification shows that the area of an elliptical cross-section A<SP>1</SP>, the diameters of which are d + a and d + b and in which the values of a and b are small is:- or A + #A, where #A is the deviation in area of the ellipse from the intended circular cross section A. In Fig. 1 two arms of a bridge circuit 7 comprise the series connected coils 3, 4, and 5, 6 of inductive displacement transducers 1, 2 respectively, the bridge output being indicated or recorded by a meter 8 scaled to read the deviations in sectional area #A. In Fig. 2, similar transduces 1, 2 each have their coils connected in separate bridge circuits 11,12 the outputs of which are proportional to section diameter and are indicated on meters 13, 14. Additionally the bridge outputs respectively energize primary windings 15, 16 of a transformer 17 and are summed by series connected secondary windings 18, 19, and indicated on a meter 20 to read cross-sectional area. The meter readings may be utilized to control the positioning of shaping tools and the contacting transducers may be replaced by ones in which the wire material itself, which must be ferrous, alters the inductance of a coil. Alternatively the gauging of diameter may be measured by dial gauges the readings of which are then mechanically summed. Specification 886,297 is referred to.
