Title: Improvements relating to the securing of slitting saws and other cutting tools to their holders or supports
Inventor: HINDLE ALBERT
IPC: B23D61/10
Filed: 1956-04-19
Abstract: 838,511. Securing saws, milling cutters &c. on shafts. RAWDON ENGINEERING & TOOL CO. Ltd., and HINDLE, A. July 19, 1957 [April 19, 1956], No. 11886/56. Class 80 (2). [Also in Group XXII] A cutting tool is secured to its holder or support by forming shallow grooves or depressions in the tool or in its gripping members, whichever is of the harder material, and the depth, form and location of the grooves is such that when the tool is gripped by the gripping members the surface of softer material is elastically deformed into the grooves to form a number of non-permanent miniature driving keys. As applied to securing a slitting or like circular saw 1 to an arbor 3, radial grooves of about <SP>1</SP>/ 16  inch wide at about # inch pitch and a few thousandths of an inch deep are formed in one or both faces of the saw and extend only over the mid portion of the face so as to leave the face plain near the cutting edge and near the arbor. The gripping collars 4, which are of toughened steel that is softer than the hardened steel of the saw, are recessed at 5 so that their grip is concentrated near the periphery. The grooves may be continuous or broken and only partly radial and they may be machined or produced by hot or cold forming, engraving, etching or embossing. The method is also applicable to securing milling cutters to their driving members or insert tools (such as lathe tools or insert milling cutter blades) to their holders.
Patent GB-1106226-A (GB)
Title: Improvements in or relating to the manufacture of electric resistance elements
IPC: C03C10/00
Filed: 1965-03-19
Abstract: A glass-ceramic body is provided with a surface layer of one or more semi-conducting oxides by incorporating into the batch to be crystallized one or more suitable metal oxides, particularly copper oxides, or equivalent metals or salts which will be wholly or partly rejected by the crystalline phase and migrate to the surface to form the semi-conducting layer. With copper oxide a reducing agent, e.g. tin or zinc is preferably also present.  The migrating oxide may be an impurity e.g. iron oxide.  The migrating oxides or equivalents may be present in pairs suitable for forming semi-conducting spinels of the AB2O4 type and selected from the oxides of iron, chromium, antimony, nickel, copper, manganese, cobalt, zinc, tin and titanium. The base glass-ceramic is preferably B-eucryptite, B-spodumene or cordierite and may have the composition SiO2 42-51%, Al2O3 32-37%, Li2O 3-11%, TiO2 4-9%, and optionally MgO 4-12% and/or B2O3 1-4% by weight.  Suitable quantities of copper oxide are up to 5%, preferably 1.5-2%. MnO2 may be used in conjunction with copper oxide, up to 10%, preferably 1.5 to 5% by weight.  If a reducing metal is present with the copper oxide the molar ratio of copper to reducing metal should be 0.5 to 2.  Surface resistivities may be controlled by the nature of the semi-conducting oxides, by the devitrefication temperature and by devitrefying in a reducing atmosphere.  In examples various glasses of the composition described and containing 2 or 5% copper oxide with or without MnO2 were melted, homogenized, shaped and devitrefied at temperatures between 800 and 1000 DEG  C. in air or a nitrogen/hydrogen mixture to give products having surface resistivities of 4.5 x 104 to 2 x 109 ohms/cm.2 (for air devitrefication) and down to 103 ohms/cm.2 (for reducing atmosphere devitrefication). The products are useful as cathode drop arrestors.

Title: Improvements in or relating to apparatus for making finned tubes by resistance welding
IPC: B21C37/22
Filed: 1942-08-27
Abstract: 554,813. Making finned tubes. THORNTON, A. A. (Brown Fintube Co.). Aug. 27, 1942, No. 12102. [Classes 83 (ii) and 83 (iv)] Welding.-In an apparatus for resistance welding longitudinal fins on tubes for making heat exchangers or structural members at least two electrodes engaging circumferentially spaced fin members extending along the tube are urged against the fins to press them against the tube and means are provided for traversing the parts which engage a number of guides to align the fins with the electrodes and a number of centering devices for guiding the tube in proper position with respect to the fins. L- or U-shaped fins are iesistance welded to the tube at a series of spots 16 by positively driven roller electrodes 21, 22 connected to the opposite terminals of a welding circuit and urged by air operated plungers towards each other. The combined peripheral length of the welded areas is greater than the length of the tube so as to allow for the decrease in section at 17 due to welding and thus to provide for the flow path of heat from the tube T to the base of the fins to be at least equal in area to the areas of the fins at a -a. The tube and fins are mounted on water cooled mandrels 51, 52 supported by carriages 44, 45 movable along I-beams 40. On each side of the electrodes are mounted a pair of guide discs 30 for guiding oppositely disposed fin elements in alignment with the electrodes. The discs 30 are carried by members 28 fixed to a frame 27 supported on a member 26. Three pairs of discs 32, 32<SP>1</SP> are also provided to centre the tube with respect to the electrodes. These discs engage the tube 454 between the fin elements. In order to weld in succession a series of pairs of fins to the tube inclined pairs of discs 34 are provided to engage the fins to index the tube from one position to the next. The peripheries of the discs 30, 34 are out of contact with the work. Four carbon steel fins of thickness about 0.031 inches may be welded to a low carbon steel tube of 2 inches diameter by electrodes having a width of <SP>9</SP>/ 64  inch, the electrode pressure being 900-1000 pounds and the current about 12,000 amps at 6-8 volts. Each weld is made in 3 cycles of a 60 cycle single phase alternating current, the current being off for a period of three cycles between welds. The fins are welded at a speed of 18 to 20 feet per minute. For a similar article of stainless steel containing 4-6 per cent of chromium with a current of about 9600 amps with two cycle off and on periods and at a speed of 12-14 feet per minute, seven slightly overlapping welds per inch are produced. If the duration of the welds includes a fraction of a cycle or if direct current is used, the direction of flow should be reversed between each weld' to prevent unequal heating on opposite sides of the tube. The machine may be reversible so that a pair of fins may be welded in each direction of traverse.

Title: Improvements relating to motor vehicles with engine exhaust brakes
IPC: F01L13/00
Filed: 1958-04-18
Abstract: 840,913. Regulating. DAIMLER - BENZ A. G. April 18, 1958 [April 27, 1957], No. 12392/58. Class 7(6). [Also in Group XXXI] In a vehicle having an engine exhaust brake 11, Fig. 1 and a manual control member 36, Fig. 1a for setting the fuel injection valve 39 to zero delivery or for an adjustable idling speed, means comprising fluid operated cylinders, 13, 30 is provided for simultaneously actuating the exhaust brake 11 and setting the control member 36 to its zero delivery position. In one example the throttle pedal 45 actuates the fuel injection valve 39 through a two-armed lever 42 which is located for idling or zero delivery by contact with a stop 33 on the lower end of a two-armed lever 32 operated from the idling speed control member 36 through a link 35. A spring 41 normally urges the arm 42 into contact with the stop 33. On application of the vehicle brake pedal 15 and cylinder 23 the mutual movement rotates a cam 16 operating a valve 20 which supplies pressure fluid to the cylinders 13, 30 to operate the exhaust brake 11 and to move the two-armed lever 32 so that the stop 33 on its lower end moves to permit the spring 41 to return the throttle valve 39 to the cut-off position. A stop 34 on the upper end of the lever 32 prevents the throttle 45 from being operated beyond the idling position. A valve 26 controlled by a governor 27 prevents operation of the exhaust brake when the engine approaches stalling speeds. In a modification the cylinder 30, Fig. 2 is mounted on the steering column and coupled directly to the idling speed control lever 36. The return movement of the throttle pedal 45 is limited by contact with a stop 49 connected to the lever 36 through a push rod 47. In a further example, Fig. 3 (not shown) movement of the accelerator 45 is automatically prevented by a linkage mechanism when the engine brake is operating.
