Abstract: 519,762. Coating metals. KLOPSTACK, H., and PEDDINGHAUS, P. F. Nov. 10, 1938, No. 32758. Convention date, Dec. 21, 1937. [Class 82 (ii)] In a method of providing a metal surface with a coating of metal by means of a blow-pipe, in which two blow-pipe burner nozzles are used in co-operation, one burner nozzle 5 is held at a sharply acute angle (less than 30‹) to the surface and melts the rod 8 of fusible metal, while an additional burner nozzle 6, inclined at a greater angle to the surface in advance of the nozzle 5 in the direction B of progress of the coating operation and fed with the same gas as the nozzle 5, tends to spread the molten metal laver over a wide area. The nozzle 6 may be larger than nozzle 5, and the nozzle 6 or both nozzles may be flattened. The angle between the axes of the burners may be such that the suction action of nozzle 6 acts at the point of intersection of their axes, and additional nozzles may be provided in front of the spreading nozzle to heat the metal that lies in front.

Title: Method of and apparatus for producing electrical heaters of desired lengths by effecting a controlled reduction in the cross-section of the heaters
IPC: H01B13/004
Filed: 1972-07-13
Abstract: 1384330 Elements BLECKMANN & CO 13 July 1972 [13 July 1971] 32866/72 Heading B3M [Also in Division H5] To obtain a metal sheathed heating element of desired length without recourse to cutting, the length of the element is measured during production and the measured length is used to control the subsequent degree of reduction of cross-sectional area of the element necessary to produce an element of the desired length. After initial reduction of cross-section of heating element 1 by rollers 2, 3 a transversely movable measuring stop 7 arrests the element 1 and causes an adjustable measuring stop 8 carried by a slide 9 to move into contact with the rear end 13 of the element. Thereupon stop 7 is removed and element 1 is conveyed by rollers 4, 5, 6, 16 and.17 to a position between pressure rollers 11, 12. When the front end 14 of element 1 engages an abutment contact 19 a cylinder 10 is pressurized to move a piston carrying a rod 21 in the direction C. A stop 23 carried by the rod 21 is arrested by stop 8 of the previously set slide 9 so that a wedge 24 carried by rod 21 is inserted between upper pressure roller 12 and manual adjusting screw 26 by the amount required to produce the desired length of element during subsequent reduction. As soon as the rear end 13 of element 1 passes an abutment contact 20, the piston carrying rod 21 and wedge 24 is moved to the right. The abutment contacts 19, 20 which are axially adjustable, determine the lengths of the ends of the element which are not to be reduced. The pressure cylinder 10 may be replaced by an electric motor drive or an hydraulic or electrical transmission may replace rod 21. If it is desired to reduce the cross-section of element 1 throughout its entire length, the movement of stop 8 may be transmitted directly to the rod 21.

Abstract: 1300897 Grinding drills BLACK & DECKER MFG CO 15 July 1971 33205/71 Heading B3D A drill sharpener comprises a stationary body 35, Fig. 3, and an abrasive wheel 39 supported adjacent the body for rotation about a central axis, the wheel having an internal frusto-conical grinding surface 61 facing the body, a passage 63 formed in the body and aligned with the surface, and means 81 provided on the body for angularly locating in use, one cutting land of a drill by engagement with one of the flutes of the drill, the locating means being adjustable relative to the body to compensate for manufacturing and wear differences in the drill. The sharpener 21, Fig. 1, is adapted to be driven by a portable electric drill 23 mounted in a stand 25 having a post 33 formed with an aperture for receiving a lug 57 on body 35 which is thereby held against rotation. The body is mounted by a bearing 43 on a shaft 41 which has an extension 55 for gripping by the chuck 31 of the drill and is secured to the grinding wheel 39. The body has a plurality of circumferentially spaced passages 63 of different diameters aligned with the frust-c@onical surface 61. A plate 79 is disposed in the lower surface of the block and has a plurality of apertures 81 aligned with the passages, each aperture having a projection 83 for engagement with a flute of a drill when in a passage 63 to angularly locate the drill. The plate is secured in position by a screw 80 passing through an elongated slot 85 which permits angular adjustment of the plate and hence adjustment of the projections relative to the passages. In another embodiment, the plate 79 has a lug 93, Fig. 8, formed with a vertical elongated aperture 93 engaged by an eccentric position 99 of a control knob 95 which, when rotated, effects the angular adjustment of the plate. Also, the passages 63 are somewhat enlarged and a second plate 105 is mounted on the upper surface of the body 35 and has apertures which are aligned with the passages and receive the drills to be sharpened. A lug 107 on the plate has an elongated aperture engaged by an eccentric portion on a knob 109 whereby the inclination of the drill, and hence the clearance angle ground on the drill, can be varied. In a further embodiment, the sharpener and a motor are formed as a self-contained unit.

Abstract: 1,148,243. Seaming non-metallic sheet material. FLUORODYNAMICS Inc. 22 July, 1966, No. 33206/66. Heading B5K. [Also in Division F2] Large diameter rolls, e.g. paper machine dryers, are provided with a covering of heatshrinkable thermoplastic material, e.g. heatsealable fluorinated ethylene polymers, by forming the covering material into a distended tube, positioning the tube about the roll to be covered, and applying heat to the tube to shrink it into a tight fit on the roll. The covering material may be distended prior to forming the tube. Forming the tube, Figs. 1, 3.-The sheet material 23, 24 is positioned on longitudinally extending flanges 11, 12, with its edges 21, 22 slightly spaced, and retained in this position by magnetic members 26. Thin foils 27, 28 are positioned respectively below and above the sheet. Members 29, 30 are adapted to be driven along the length of the seam, and comprise pressure plates 31, 32 with a small central electrically heating area, surrounded by water cooling tubes 39, 40 to limit the heating to the adjacent edge portions of the sheet. To join the two sheet sections, the members 29, 30 are brought up to the required heat, and are then driven by motor 49 along the length of the join, the sheet material first thermally expanding substantially into contacting relation and then flowing and fusing together to form a butt seam. On disconnecting members 29, 30 from their driving cables 41, 42, the formed tube may be removed from flanges 11, 12 by drawing a wall portion of the tube between rollers 15, 16. By appropriate loading of the rollers and by moving the tube, the seam may be calendered as the tube is removed. Distending the tube, Fig. 7 (not shown).-The tube is placed around two spaced rollers (50), (51) supported on arms (54), (55) expanded by an hydraulic piston-and-cylinder (56), (57). By driving the rollers in the same sense, the tube is uniformly distended. Alternatively, Fig. 8 (not shown), each end of the sheet, prior to being formed into a tube, is wound round a roller, each roller being driven in an opposite direction to distend the sheet, leaving unstretched end portions. The flanges 11, 12 and associated sealing means of the tube forming apparatus are then placed on the roller to be covered, and the distended sheet formed into a tube about the roller and flanges. Shrinking the tube, Fig. 10.-The tube is placed on the roll 74 with one end 70 extending. A source 71 of hot air is then rotated around the extended end 70 of the tube to shrink it, as shown, to fix that end. The other end is then resiliently held by springs (86), Fig. 11 (not shown), to apply axial tension to the tube and to maintain it in concentric relation to the roll. The source 71 is then moved axially along, and around the tube to shrink it into a tight fit on the roll.
