Title: Method of and apparatus for facilitating the separation of imperfectly welded tubes from properly welded tubes
IPC: B21C37/08
Filed: 1938-09-20
Abstract: 519,537. Making tubes. DEUTSCHE ROHRENWERKE AKT.-GES. Sept. 20, 1938, No. 27329. Convention date, Dec. 29, 1937. [Class 83 (ii)] In a method of facilitating the separation of imperfectly welded tubes from properly welded tubes at the rear of a continuously operating roll welding mill, a device is provided for chemically marking the imperfect tubes in colour, the tubes so marked being separated from the properly welded tubes on one of the succeeding conveyers. The skelp passes from a furnace a through pairs of welding rolls b and a saw d for cutting it into lengths. Between the welding rolls and the saw is arranged a marking device e consisting of a hopper m for a salt mixture such as common salt and potassium bichromate which when sprayed on the tube leaves behind black lines. The hopper m is provided with a shoot o and contains a grooved distributing roller n which may be connected by chain gear to a roller s. The hopper is secured to a counterweighted lever p which is pivoted to the framing r and carries the roller s. When the operator on the platform g observes that no dross is dripping from the weld between the first and second pairs of welding rolls and so indicating that the weld is unsatisfactory, he operates a switch h, which energizes an electromagnet u and so through levers v, p and rod w lowers the roller s on the tube c, which causes the distributor roller to rotate and thus the tube is sprinkled with the salt. The operation of the switch h also operates a signal k so that the operator at the hot bed l may remove the defective tube. The sprinkling device may be directly operated by an electric motor or the marking composition may be pressed on the tube by levers controlled magnetically. The marking' and signalling devices may be actuated together by compressed air &c.

Abstract: 812,196. Aerials. GENERAL ELECTRIC CO. Ltd. Oct. 30, 1957 [Sept. 12, 1956], No. 27950/56. Drawings to Specification. Class 40 (7). The invention relates to aerials of the type comprising an active element or array and a dish-shaped surface reflector. In such aerials, in addition to the main lobe of radiation, there are several side lobes and it is thought that these side lobes are due, at least in part, to the sharp electrical discontinuity between the edge of the metal reflector and the surrounding medium. According to the present invention the sharpness of the discontinuity is reduced by means of a strip of material affixed to the surface of the reflector, and adjacent its edge, having an electrical resistance at the frequency of operation higher than that of the remainder of the reflector. The strip may be of uniform width and may be tapered in cross-section, the taper pointing towards the axis of the reflector, thus increasing the resistance per unit area radially outwards, or the strip may have its inner edge cut in a zig-zag line so that, in the extreme case, the strip becomes a series of triangles having their bases adjacent the edge of the reflector.
