Title: Improvements in or relating to the production of wrought goods of magnesium base alloys
IPC: C22F1/06
Filed: 1938-05-28
Abstract: 496,539. Forging magnesium alloys with heat-treatment. MAGNESIUMELEKTRON, Ltd. May 28, 1938, No. 15996. Convention date, June 7, 1937. [Class 83 (iv)] In the production of improved forgings from alloys with a high percentage of magnesium and of a precipitation hardenable content the work pieces are forged at temperatures within the solid solution range after which they are immediately quenched and finally annealed under conditions producing a hardening precipitate without causing recrystallization of the crystal structure. The final annealing is effected at temperatures below about 200‹ C. With an alloy containing about 8 to 9 per cent of aluminium the forging is effected between about 320 to 400‹ C., and the final annealing between about 140 and 180‹ C. An example is given of treating a blank to form a propeller. A blank is cut from a section of a homogeneous magnesium alloy containing 8À5 per cent Al, 0À5 per cent Zn, and 0À2 per cent Mn and previously extruded to produce required grain. The blank at a temperature of 370 to 400‹ C. is placed in a press with dies heated to a temperature of 300 to 350‹ C. and converted into an intermediate shape. After reheating to a temperature of 340 to 360‹ C., the work is forged between heated dies in a hydraulic press. Subsequently the propeller blank is quenched in water and annealed.

Title: Improvements in or relating to monogrammic apparatus for advertising
IPC: G09G3/00
Filed: 1932-06-10
Abstract: 382,250. Monogrammic signs. HARTOGS, I., 22, Badhuisweg, The Hague, and KLEPPE, J., 2, Verzijdenstraast, Rotterdam, both in Holland. June 10, 1932, No. 16504. Convention date, July 10, 1931. [Class 118 (ii).] A monogrammic sign comprises lamp panels 2 travelling as an endless chain round wheels 1 and carrying switch levers 7 which are closed, to light the lamps in selected combinations, by selected rows of pins or rollers 14 on a rotatable drum 13. In order to bring a selected row of pins 14 into the operative position 38, the drum 13, which' is normally driven continuously through a magnetic clutch 20, 18, is stopped by the manual depression of the selected key 23. Current then flows from a battery 40 through wire 41, key 23, and a lead in the cable 22 to a terminal contact in a vertical row 42. When the rotating drum 13 brings into engagement with this selected contact the corresponding portion of a helical strip 16, the circuit is completed through slip ring 17, wire 43, switch, coil 26, wire 45, and battery 40. The armature 27 is attracted and breaks the circuit of battery 47 through the magnetic clutch, the drum 13 being thereby declutched from the driving pulley 21. At the same time, the armature 27 closes a circuit to energize a brake-actuating coil 25. After the levers. 7 have moved past the line 38, a pin 32 on the lamp panel moves a switch lever 33 to close a circuit through a coil 30 in order to release the key 23 from its holding pawl 31, and permit rotation of the drum 13 once more. A signal lamp 52 indicates when another key may be depressed. After travelling the required distance the display panel passes abutments 53 which displace pawls 8 and release the switch members 7, the lamps being thus extinguished. To protect the contacts 10, 11, each panel may be fitted with a main current quick-break switch adapted to be closed by a stationary abutment after the levers 7 have been depressed, and to be opened by another abutment prior to the pawls 8 being released. The coil 25 may actuate a band brake or may interpose an abutment in the path of a gear rim.
