Abstract: 708,015. Circular looms; shuttles. CASATI, G., and CAZZANIGA, C. July 20, 1951 [Jan. 3, 1951], No. 17294/51. Class 142(2) The shuttle of a circular loom comprises two rollers 14, 15 of magnetic material supported between brackets 16, 17 carrying a funnel 21 for the spool of weft yarn and adapted to be maintained in position to pass between the warp threads by an electromagnetic or permanently magnetic roller 1 revolvably mounted about the main shaft and rotatably driven through gearing 13. The roller 14 has a centrally reducted portion and its ends are connected by rubber bands 19 to the roller 15. An additional guide roller 7 is mounted adjacent the magnetic roller 1 so as to maintain the shuttle in position by providing a rotatable abutment against which the roller 14, through the warp threads; rests. A sprocket wheel 14<SP>1</SP> is provided at each end of the roller 14 and 'serves to engage the warp yarns passing between the rollers 14 and 1 and maintain them in vertical alignment. In addition, the upper sprocket wheel 14<SP>1</SP> engages a spring-loaded disc 39 which is normally permanently displaced but which - upon the shuttle becoming disengaged from the roller 1 moves under the influence of a spring and actuates levers 45...47 connected to a mercury switch to stop the machine. A similar switch is also provided for effecting stoppage of the machine in the event of yarn breakage and is controlled through levers 27, 28. 29 from a yarn guide 25 pivotally connected to an arm 26. The yarn guide which is of V-shape section and tapered towards one end is adapted to swing when the yarn breaks and release catch lever 29 carrying a rotatable disc 30. This disc thereupon engages a second disc mounted on a lever connected to the switch and thereby actuates the stop mechanism.

Title: Improvements in automatic sheet feeding apparatus
IPC: B65H1/30
Filed: 1945-07-09
Abstract: 595,921. Feeding sheets. HOE & CO., Ltd., R., ROBINSON, Ltd., E. S. & A., BATTEY, A. P., and FOWERAKER,T. S. July. 9, 1945, No. 17457. Addition to 518,804. [Class 100 (i)] The sheet-feeding apparatus described in the parent Specification in which a pile of sheets is advanced automatically to feed position by chains fitted with bars 2 for supporting the pile, and secondary chains are provided for feeding a new pile into position without disconnection of the feed is modified by substituting for the secondary chains thrust members such as screws 10 and nuts 9 to which are attached supporting bars 6 on which rests laths 7 for supporting the pile. Also instead of controlling the driving means for the screws 10 automatically by feelers a variable speed member 14 may be used to drive them at a speed which is set to synchronize with the automatic feed. Such a variable gear may comprise a ratchet mechanism, Fig. 5, comprising a pawl 20 oscillated from the fed machine and adapted to drive either freely mounted outer ratchet 17, or. when permitted by a deep groove 18, an innerratchet 16. Also when desired a mask 19 may be adjusted to allow the pawl to engage the ratchet earlier or later in its stroke and so adjust the ratchet action. The bars 6 and laths 7 may be replaced by a plate which is directly attached to the secondary'chains or thrust members. The bars 6 may be pivoted to the thrust members in such a way that as the laths are raised the bars are tripped aside and then return to engage the laths automatically. The primary chains may also be replaced by thrust members, and these may be in the form of racks engaged by pinions.

Abstract: 1507203 Heat-treatment of metals by lasers CATERPILLAR TRACTOR CO 30 April 1975 [12 July 1974] 17974/75 Heading C7N The bore surface of a workpiece, e.g. of Fe, is heat-treated by directing a laser beam on to the surface by one or more mirrors and moving the bore surface relative to the mirror(s). In an embodiment, Fig.1, the workpiece 12 is rotatably supported on rollers 46, 48 driven by motor 56, the laser beam 18 is reflected on to the internal surface of the workpiece by mirror 38 held on arm 30, and a motor 62 moves the table 40 along a rack 26 so that the workpiece is moved relative to the beam 18 and mirror 38, the zone of localized heating 66 thus moving in a helical path over the surface. An alternative embodiment, Fig.8 (not shown) discloses a movable and rotatable watercooled mirror such that no movement of the workpiece is necessary. A further embodiment, Fig.9 (not shown), discloses a conical mirror reflecting the beam radially into an annulus. Other embodiments involve the use of a series of mirrors, one of which is oscillatable, resulting (a) in a beam directed on mirror 38, Fig.3 (not shown), and (b) in a beam directed on to the bore surface, Fig.10 (not shown), this latter example having the mirrors enclosed in a rotatable housing.

Title: A process for reducing iron ore
Inventor: PORTER WALTER JAMES
IPC: C21B13/00
Filed: 1966-04-25
Abstract: In a multi-stage fluidized bed process for the reduction of iron ore a carbonaceous fuel and oxygen-containing gas are burnt in an intermediate stage under such conditions that the ore is reduced to ferrous oxide while heat is provided for the subsequent reduction to metal.  The gases produced in this zone pass to the initial zone, where the ore is pre-heated and pre-reduced while the gases undergo a catalytic reaction in the presence of ferric oxide, carbon monoxide and water vapour reacting to form carbon dioxide and hydrogen. The gases leaving the initial zone are cooled to remove water and treated to remove carbon dioxide, after which they are pre-heated and circulated through the one or more reduction stages which follow the intermediate stage and in which the ferrous oxide is reduced to metallic iron.  It is said that by operating in this way problems of carbon deposition in the apparatus due to catalytic decomposition of carbon monoxide are eliminated. Preferred temperatures and gas ratios for the various zones are given.
