Abstract: 864,930. Pulverulent fuel burner. TEXACO DEVELOPMENT CORPORATION. Oct. 25, 1957, No. 33371/57. Class 75(1). [Also in Group XII] In producing a mixture of carbon monoxide and hydrogen in a cylindrical reaction vessel 1 lined with refractory material 2, powdered solid fuel entrained in a gasiform carrier is introduced through a conduit 20 tangentially into a centrifugal separator 21, part of the gasiform carrier is removed through line 22 and valve 23, whilst the powdered fuel entrained in the remaining carrier is passed as a swirling stream through conduit 11 into the vessel 1 substantially along its axis. Free oxygen containing gas is fed through an annular passageway 13, between coaxial conduits 10, 11, into the vessel 1 so as to surround the swirling stream. The reaction products are withdrawn through a nozzle 6. The gasiform carrier may be steam, between 10 and 90% of the steam being withdrawn through line 22. The conduit 20 passes from a circular to a rectangular cross-section on approaching the separator 21, the conduit entering the separator with its longer side tangential thereto. A cooling coil 17 supplied and discharged through lines 18, 19, prevents the burner conduits from overheating. In a modification the oxygen-containing gas is fed in through a conduit coaxial with, and within, the conduit 11.

Title: Improvements in or relating to button hole sewing machines
IPC: D05B3/06
Filed: 1956-11-08
Abstract: 848,453. Sewing machines. PFAFF A. G., G. M. Nov. 8, 1956 [Nov. 15, 1955], No. 34107/56. Class 112 [Also in Group XXV] A buttonhole sewing machine comprises a cord guide 45 carried adjustably by a guide bar 52 which is movable longitudinally against the bias of a spring 107 into a starting position and is released for return to its initial position upon reversal of direction of the work feed, the bar also being swingable laterally, and adjustable stops for limiting the longitudinal and swinging movements of the bar being provided, whereby the cord guide moves in an arcuate path about the needle at each reversal of the work feed. Guide 45 is in the form of an eye situated above the feeding foot 7 and provided in a bar 41 adjustably carried by a bar 43 in turn adjustably carried by a bracket 50 fixed to bar 52. The latter is formed with a longitudinal slot 56 engaged by a horizontal pin 57 fixed in a cylindrical member 58 journalled about a vertical axis in a housing 53 carried by a double-armed lever 55 pivoted at 54. A nose 73 at the front end of bar 52 is normally biased by the spring 107 into contact with an adjustable stop 103, when a pin 80 mounted transversely on bar 52 is biased by a spring 144 into abutment with an adjustable stop 83, the guide 45 then being in position for the sewing of the right hand side of the buttonhole. When the feed bar 6 is raised, for insertion of work, by lowering a lever 27, a cam surface 116, formed on a bar 115 connected to lever 27, co-operates with a roller 113 on the rear end of bar 52 to move the latter rearwardly. Pin 80 then rides over a rounded edge of an abutment 99 to lodge behind the latter and in contact with an adjustable stop 82, guide 45 being thereby moved into position for the sewing of the left hand side of the buttonhole. On release of lever 27 and starting of the machine, the left hand side is sewn, and on completion of said side a cam 140 provided on the control disc 5 co-operates with a lever system to move a spindle 119 laterally against bar 52. The latter is thereby swung to disengage pin 80 from abutment 99, when guide 45 returns to the position for the sewing of the right hand side of the buttonhole. In a modification the machine is arranged to sew twice around the buttonhole. After the sewing of the left hand side, a cam 166 on the control disc shifts spindle 119 for swinging bar 52 to position guide 45 for the sewing of the right hand side. On completion of the latter, a cam 168 closes a switch for energising a solenoid 161, the armature of which is connected to the upper end of a double-armed lever 151 pivoted at 154, which thereby swings, and its lower end co-operates with a roller 148 on bar 52 for moving the latter rearwardly. Pin 80 is thus engaged with stop 82, and guide 45 is positioned for the second sewing of the left hand side, on completion of which a cam 167 actuates spindle 119 to return pin 80 to stop 83 for the second sewing of the right hand side.
