Abstract: 648,300. Weighing apparatus. TRIGGS, W. W. (Yale & Towne Manufacturing Co.). Aug. 8, 1946, No. 23559. [Class 143] Pendulum - weight apparatus; indicating mechanism.-A weighing scale with a rack and pinion driven indicator, has the rack yieldingly held up tc the pinion by magnetic means. The invention is shown embodied in the pendulum scale of Specification 648,370. Each of the two pendulums 10, 11 is adjustable by screws 25, 26, has a pivot shaft 16 running in ball-bearings and is operatively connected with the load platform by means of a steel band 18, a common coupling member 20 and a pull-rod 23. Extending laterally from each pendulum, at the pivotal axis thereof, is an arm 27, 31 with a roller 29, 33 at its outer end. The two arms cross one another and their rollers engage slots 38, 37 in the horizontal limbs of a T-member 36 whose vertical limb is racked at 41 for driving engagement with a pinion 42 on the weight indicator shaft 43. With the arms 27 and 31, as shown, at right-angles to the lengths of their respective pendulums, the edges of the slots 37, 38 are horizontal for the weight scale to be linear. If the angle of the arm deviates from a right-angle, a linear scale is obtained by correspondingly inclining the slots 37, 38' to the horizontal. Such an arrangement is illustrated in Fig. 7 (not shown). To maintain the rack 41 in yielding driving engagement with the indicator pinion 42, flanged ferro-magnetic plates 48 are fixed to it to travel vertically over the pole faces 49 of a stationary permanent magnet 50.

Title: Improvements in and relating to the reduction of metal-oxygen compounds
IPC: C21B13/00
Filed: 1935-08-26
Abstract: 466,592. Extracting iron &c. UHDE, F. Aug. 26, 1935, No. 23881. Void. Convention date, Aug. 28, 1934. [Classes 72 and 82 (i)] The reduction of metal-oxygen compounds such as chromite, roasted zinc blende tin stone or iron ores by gaseous reducing agents at temperatures below the melting point of iron is effected at high pressures. The compounds are fed from a bunker 3 through inlet devices 2 into a pressure-tight furnace 1 and are reduced by cold gases fed by a pipe 4 and preheated gases at the point 5, both gases being under high pressure. The gas leaving the furnace at the point 6 may be passed through a heat exchanger 9, a cooler 10 freed from carbon dioxide in a water pressure washer 11, passed through a pump 12 to increase its lost pressure and then into the furnace at the point 4, 5. The stream to the point 5 is passed through a coil 15 in a furnace 13 in which some of the exit gases from the point 6 are burnt with air, the reaction products being used, e.g. to drive compressors 14. To obtain higher temperatures in the furnace oxygen may be blown in to the furnace at the point 8. Ores such as zinc blende calamine or pyrites are preferably roasted before being reduced. The reducing gases may be produced from hydrocarbons by preheating the latter under pressure and cracking them. Pulverulent compounds to be reduced may be blown into furnace instead of being fed in from the bunker 3.

Abstract: 492,787. Feeding sheets. FORGROVE MACHINERY CO., Ltd., and RUSSELL, A. Sept. 1, 1937, No. 23896. [Class 100 (i)] Labels, blanks, or other sheets are removed from a pile by a peeling action, so as to facilitate separation. A suction or adhesive separator may be used and may act upon the bottom sheet of a horizontal or the top or bottom sheet of an inclined pile. As applied to a suction separator acting on the bottom of a pile a, the separator comprises a pair of rollers e, e<1> carried by a reciprocating carriage g<2> which is moved to the right from the position shown when the front edge of the bottom sheet has been drawn into contact with suction orifices e<2> in the rollers e, e<1>. As these are moved to the position shown by dotted lines in Fig. 1, the bottom sheet is stripped from the pile. The pile is normally supported by bands d attached to fixed clamps d<2> and to the rollers e, e<1>, and these bands are wound on the rollers during the stripping action due to rotation of the rollers by a pinion f<1> and a fixed rack< >f<2>. The pile is however supported during the separating action by fixed prongs i, Fig. 1, secured to the carriage g<2>, or by a belt m, Fig. 6, fixed at m<1> and supported by rollers l<1>, l<1> on the carriage. As the carriage moves to the right the belt m passes between the sheet being separated and the rest of the pile. Instead of rotating the rollers e<1>, e<1> by rack-and-pinion mechanism they may be actuated by a spring motor. Double feed is prevented by the action of an adjustable diamond shape stripper j made of razor-blade metal.
