Title: Apparatus for rolling fins on non-rotating tubes or rods
IPC: B21C37/20
Filed: 1969-05-28
Abstract: 1,208,097. Rolling tubes. CALUMET & HECLA CORP. 28 May, 1969 [26 Aug., 1968], No. 26966/69. Heading B3M. Apparatus for finning rod or tube comprises a rotatable finning head 76 having an elongated opening therethrough coincident with its axis of rotation, a plurality of finning rolls 90 on the head 76 for rotation thereon about an axis inclined to the axis of rotation of the head, and gearing connected to each of the finning rolls 90 to drive the rolls in rotation at a speed determined by the speed of rotation of the head to effect axial advance of an elongated rod or tube of circular cross-section through the head and formation of helical fin convolutions thereon without rotation of the rod or tube. The head 76 is rotated at a substantial speed via rotary members 36, 40, 44, 54, 56 and 58 by a belt driven pulley 32 and the finning rolls 90 are driven by planetary gearing 124, 130, 136 138 and 144, including a substantially stationary sun wheel 50, rotating a universal joint 94. The finning rolls 90 can be moved inwardly or outwardly by activating a piston and cylinder device 116 which moves a support 112 axially so that when ring 106 is moved from the left to the piston shown in Fig. 1B, a roller 100, acting against cam surface 98, will cam the tubular portion 86 inwardly to the forming position. In operation the workpiece is fed through the apparatus until the desired zone for the fins is reached whereupon the finning rolls 90 are cammed inwardly. If the workpiece progresses slowly in either direction as a result of a difference between the actual speed of rotation of the rolls and the theoretically correct speed of rotation, the drive means 30 is adjusted to effect a slow compensating rotation of the sun gear 50.

The weft thread is now freed from the gripper 5 or 6 and drawn back against the resistance of some brake 16, 17 until its end is at or near the edge of the fabric, as shown in Fig. 5. The braking may be due to suction forcing the weft thread against the warps.

Filed: 1960-08-10
Abstract: 1,007,538. Selective signalling. ENGLISH ELECTRIC CO. Ltd. Nov. 10, 1961 [Aug. 10, 1960], No. 27697/60. Heading G4H. An apparatus for indicating the position, relative to a datum, of a continuously moving body comprises photo-electric means which controls generators, the arrangement being such that the correct position is indicated whatever the speed of the body, assuming the speed of travel in the inspection zone is substantially constant. Compensation for small changes in speed and acceleration of the body can be made. In the Figure a billet 10 travels from left to right. A series of photo-cells 13 spaced at onefoot intervals detects the leading edge. When 13a gives an output, generator 16 gives a linearly increasing output voltage, and when 13b gives an output the generator is reset and the level to which its output had risen is stored in unit 17. Cell 13b also starts a second generator 19 whose output voltage has a slope twelve times that of generator 16. Its output is compared with the stored voltage and when equality is reached the generator 19 is reset and restarted and an " inches " indicator 14b stepped by one. The output from cell 13b is further used to step a " feet " indicator 14a by one. Switch 15, controlled by indicator 14a, moves on one step each time a cell 13b, 13c ... is actuated. Thus, assuming constant speed of the billet, the instantaneous position of the leading edge relative to the cell 13a is indicated on unit 14. The generators may be replaced by pulse generators and counters the latter giving an analogue or digital output comparison purposes. Specification 988,791 is referred to.

Title: Electrically conductive article
Inventor: COLBERT WILLIAM HARRY
IPC: H01B1/00
Filed: 1952-11-04
Abstract: An article having a light transmission of at least 50 per cent comprises a body of glassy siliceous material and a continuous layer on the body composed of an intimate molecular mixture of a metal and a metallic inorganic dielectric compound, the proportions of the layer being such that it is electrically conductive.  The layer may be used to cause adherence of a pure metal layer directly to the siliceous base or may be used to cause adherence of a protective layer, e.g. silica, to an underlying metallic conducting layer.  The metal forming the layer may be Cu, Au, Ag, Al, Pt, Rh, Ni, Fe, Co, Sn, Ti, Cd, Zn, Cr, Mg, Mn, Pd, Zr, V, Pb, As, Sb, Bi or the alloys "Monel" (Registered Trade Mark) and "Nichrome" (Registered Trade Mark).  The dielectric compound employed may be: an oxide, sulphide, sulphate, selenide, selenate, telluride, tellurate or halide e.g. of Pb, Ag, Al, Mg, Zn, Cd, Sb, Bi, Hg, Cu, Pt or Pd; a sulphide of Sn, As, Fe or Ni; lithium fluoride; mixed oxides or compounds e.g. spinels.  The layer may be put on the base by thermal deposition or by sputtering and the article may be baked e.g. at 600 DEG F., after the coating step.  A layer with the proportion of metal and dielectric uniform throughout may be obtained (a) by simultaneous thermal deposition of metal and dielectric on to the base or (b) by the thermal evaporation of a mixture of non-oxidisable metal, e.g. Au, and an oxidisable metal, e.g. Al, or compound e.g. sulphide, on to the base followed by oxidisation of the metal or compound.  A layer in which the proportion of metal and dielectric varies throughout its thickness may be obtained by thermal evaporation of a mixture of metal and dielectric compound which have different evaporation rates.  Numerous examples are given of the production of articles e.g. windscreens and radar plotting screens.  Specification 693,127 [Group III] is referred to.

Title: Improvements in or relating to the purification of sulphur
Inventor: BURDEN FREDERICK ALAN
IPC: C01B17/02
Filed: 1950-11-13
Abstract: Sulphur is recovered from spent oxide and is purified from high molecular weight impurities such as tar by extracting with a hydrocarbon solvent at elevated temperature, slowly cooling the extract with rapid agitation to precipitate substantially pure sulphur free from the hydrocarbon impurities which remain in p solution, removing the purified sulphur from the liquid, and finally removing traces of solvent from the sulphur.  The hydrocarbon solvent employed may be benzene, toluene, xylene, naphtha or a mixture of any two or more of these liquids.  Crude benzole may also be employed in which case it may be desirable to operate at pressures above atmospheric pressure.  The rate of cooling of the hot extract is preferably between 10 and 20 DEG C per hour.
