Title: Improvements relating to the manufacture of flux-cored solder wire
IPC: B23K35/02
Filed: 1947-12-04
Abstract: 625,450. Making solder wire. ENTHOVEN & SONS, Ltd., H. J., and VILLE, W. A. DE Dec. 4, 1947, No. 33439/46. [Classes 83 (ii) and 83 (iv)] [Also in Group XXX] Angular bending; reeling.- In making flux-cored solder wire by charging a U-shaped travelling solder strip with core material and bending over the edges to form a tube, granular or powdery flux material is fed to the strip by allowing it to flow from a hollow rotary flux feeder having a circumferentially extending outlet aligned with the travelling strip. Strip metal 1 is drawn from a drum 2 between ribbed and grooved channeling rolls 3, 3<SP>1</SP> and then passes under a rotary device 4 for feeding powdered core material to the channel and after having the channel closed by rolls 5, 5<SP>1</SP> to tubular form, is then passed over a power driven tensioning drum 6 and then through a traversing guide 7 to a storage drum 8. The tensioning drum 6 which draws the tube through the rolls 3, 3<SP>1</SP> is driven by belt gear from a motor 9, and is connected by a belt 12 to the drum 8, which through a belt 13 operates the guide 7. The rolls 5, 51 are driven by a belt 11 but the rolls 3, 31 are rotated by friction with the strip 1 and by belt gear 15, 14 respectively drive a screw conveyer 2, Fig. 3, for the powdered flux and a pair of shallow cones 18, 19 adjustably connected together by spacing bolts, which discharge the flux from the peripheral gap between them into the channeled strip which is guided between walls 22 enveloping it. The powder is thus discharged radially at a speed proportional to the speed of travel of the strip. As the channel leaves the vicinity of the feeder the powder is levelled off by an adjustable finger. A sealing strip 17, Fig. 10, of solder is fed into the channeled strip just above the core material before passing through the closing rolls 5, 51 to prevent escape of the core material. The U-shaped channel may alternatively be formed by extrusion.

Filed: 1922-12-14
Abstract: 199,349. Picturadio Corporation, (Assignees of Keen, E.). June 13, 1922, [Convention date]. Drawings to Specification. Copying telegraphs. - In the transmission of pictures to a distance a representation of the picture is first formed on which light and shade variations are represented by raised lines or corrugations adapted to co-operate with a stylus to produce sounds as in a phonograph, which are converted to corresponding current variations and transmitted by wireless, or to produce groups of current impulses of definite frequency, the number of impulses per group depending upon the intensity of tone of each picture element. The receiver reproduces the picture photographically under control of the received current variations, and is synchronized by a start-stop device under control of impulses from the transmitter end sent at each rotation of the transmitter and of a frequency different from that of the picture impulses. The received picture currents after successive passage through a radio-frequency amplifier, detector, audio-frequency amplifier, and audio-transformer pass through the wire of a stretched wire galvanometer.

Title: Improvements in and relating to the manufacture of continuously loaded signalling conductors and like members and lapping machines for use in the manufacture thereof
IPC: H01B13/08
Filed: 1931-12-09
Abstract: 393,961. Conductors. SMITH, W. S., Benchams, Newton Poppleford, Devon, and GARNETT, C. V. H., Woodhall, Woodland Rise, Sevenoaks, Kent. Dec. 9, 1931, No. 34185. [Class 36.] In a machine for covering a conductor with loading tape or similar processes, comprising rotating heads carrying bobbins of tape, the tape passes over three rollers, two mounted on the head and one on a sliding bolt carried thereby, so that if the tape breaks or slacks the bolt moves under centrifugal force to actuate clutch and brake mechanism for stopping the machine. The head 10 rotates about a fixed central tube 13, through which the conductor passes, and carries a bobbin 35 adjustably mounted in guides 38, and an adjustable balance weight 39. The tape A passes from the bobbin 35 over rollers 45, 44, 43 to the conductor. The roller 43 is mounted on a radially-sliding bolt 42, the tension of the tape being balanced by a spring 46, so that the bolt is normally in a central position on the head 10 ; if the tape breaks or slacks the spring 46 moves the bolt into an out-of-balance . position, so that it flies out under centrifugal force until restrained by stops and strikes a lever 54 which actuates the clutch lever 26 and a cam 32 actuating the brake blocks 34 through the linkage shown. The clutch and brakes are also operated on opening a cage surrounding the beads. The balance weight 39 may be replaced by a second bobbin and the bobbins may be disposed vertically. To prevent the tape from shifting on the bobbins it may be coated with adhesive material which may be the coating and spacing material described in Specifications 282,504, [Class 36, Electricity, Conducting &c.], 368,304 and 393,634.
