Heating by electricity.- A wire fed mechanism for automatic or semi-automatic arc welding machines comprises feed rolls rotatable on axes tilted slightly in opposite directions from parallelism with the line of the wire feed and rotated about that line, one or other of the rolls being brought into engagement with the wire according to the direction feed. In an automatic arc welding machine two pairs of feed rolls 1, 2 are provided, one roll of each pair being mounted in a frame 5 and the other rolls in a frame 6 pivoted thereto at 10. The frame 5 is keyed to hollow shafts 14, 15 through which the wire passes, the shaft 14 of which is rotated by a constant speed motor 7 through a coupling 22 and worm gear 24, 25, a shield 26 preventing oil &c. from reaching the casing 20. The casing has a covered opening through which access to the rolls is obtained. The pairs of rolls are arranged with their axis inclined to the line of wire feed and crossed relatively to each other so as to feed the wire in opposite directions when the shaft 14 is rotated. Each roll is carried by a bushing 11 angularly adjustable by worm gear 13 to vary the feed. The upper end of the frame 6 has a lug 27 fitting over a crank 29 pin-connected to links 31 joined to the pins 32 of a cross head 33 which is carried by a rotatable hollow rod 34. The rod 34 is connected through a bearing 36 to a cross-head 35 connected to a frame 37 which is pivoted at 38 to the cover 18. The frame is controlled by solenoids 8, 9 responsive to a characteristic of the arc that varies with the arc length as described in Specification 232,995, so as to operate the rod 34 and thus bring the desired pair of rolls into operation.

Title: Novel process for the catalytic hydrogenation of aromatic hydrocarbons
Inventor: THONON CLEMENT
IPC: C07C5/10
Filed: 1962-09-13
Abstract: Cycloaliphatic hydrocarbons are obtained from aromatic hydrocarbons by passing with at least the stoichiometric amount of hydrogen into a first, liquid phase, reaction zone containing the desired cycloaliphatic compound and a solid, suspended catalyst, maintaining a molar aromatic: cycloaliphatic ratio in the first zone constant at 0.003-0.1, removing effluent from the first zone in the gaseous/vapour phase and passing the effluent through a second, gaseous phase, reaction zone containing a solid catalyst. Benzenes are converted to cyclohexanes and naphthalene into tetra- or deca-hydronaphthalene. The first stage is effected at 1-100 atmospheres and 80-250 DEG C., preferably 10-100 DEG C., below the boiling-point of the cycloaliphatic hydrocarbon at the reaction pressure.  The same conditions may be used in the second zone; preferably extra hydrogen is added to prevent condensation. The catalyst in each stage is preferably a Group VIII metal and may be supported.  Cycloaliphatic hydrocarbon is recovered by condensation and excess hydrogen recycled.

Title: Improvements in or relating to glassware forming machines
IPC: C03B9/16
Filed: 1963-09-05
Abstract: A centring device, for the inverting mechanism of portable neck moulds on a glassware forming machine having neck moulds carried by mould support arms which are slidably mounted for movement by motors axially inwardly and outwardly on the horizontal inverting shaft rotatably supported on the machine frame, is characterized by annular guide surfaces centrally located on said shaft and a guiding element affixed to the machine frame engaging said shaft guide surfaces to maintain the inverting shaft in a fixed lateral position relative to the forming machine frame. A " double gob " machine has neck moulds 10a, 10b with halves 11, 12 on supports 13, 14 connected by dovetails to bosses 17, 18 which are integral parts of internally splined sleeves 19, 20 which fit over complementary splines 21 on enlarged central portions 22 of the invert shaft 23.  The sleeves 19, 20 are adapted to rotate with the shaft 23 which is mounted in end bearings 24 held in journals 25 attached to the machine frame 26. The shaft 23 is rotated by the action of a vertically disposed rack 28 acting on a pinion 27 attached to the shaft.  The opening and closing of the neck moulds is effected by fluid pressure <PICT:0975589/C1/1> motors in the sleeve ends, pistons 29 being attached to the sleeves and sliding on the end portions of the shaft 23, the pistons having end bosses 31, which abut against stops 32.  The pistons move against the action of coil springs 36, and thus cause the mould supports 13, 14 to slide apart along the splines.  To ensure that the centre line of the neck mould remains the same during inversion the outer surfaces of the pinion 27 rotate in a bifurcated fork-like member 42 bolted at its lower bracket on to the machine frame (see Fig. 2, not shown).  An expansion gap 41 is left between the journal ends and that of an end cap 33 of the sleeves.  U.S.A. Specification 1,911,119 is referred to.
