Filed: 1932-05-25
Abstract: 399,263. Control of two motors. SUNDSTRAND MACHINE TOOL CO., 2531, 11th Street, Rockford, Illinois, U.S.A.- (Assignees of Dumser, L. A. ; 2531, 11th Street, Rockford, Illinois, U.S.A.) May 25, 1932, No. 14864. Convention date, Jan. 15, 1932. [Class 38 (iii).] Travelling between predetermined limits.-A milling or like metal-working machine has a reciprocatory member driven by an electric motor through feed-traverse gearing, and electrically-operated coupling means for changing from feed to traverse and vice versa. The traversing mechanism for the reciprocatory work table 12, Fig. 3, comprises differential screw mechanism and spur gearing rotated by chain and sprocket gear from-an electric motor 45 (shown dotted). The change from feed to traverse is effected by aT-lever 78 controlled by solenoids 83, 84, the circuit for these being arranged to operate in conjunction with a separate electric motor 21 for the tool spindle and dogs D, D<1>, D<11> on the table. Closure of a start button 180, Fig. 6, closes the circuit of a self-maintaining contactor 161 which effects starting of the spindle motor 21. The feed motor 45 is started similarly by pressing button 240 closing the forward contactor FC ; the contacts 251 are momentarily connected to one side of coil FCC through interlock contacts 202 of reverse contactor RC, in this manner a holding circuit is established through the interlock contact 202 and control relay 265 which closes immediately after forward contactor closes. The table moves towards the right, Fig. 5, at quick traverse, until dog D<1> engages the plunger of switch S<1> whereon coil 140 of the solenoid 84 is energized and slow feed engaged as explained above. Movement continues until D<11 >engages switch S<11> whereupon the circuit to the forward contactor is broken and interlock contacts 192 are connected and a circuit to the reverse contactor coils completed which reverses the motor 45 ; simultaneously the coil 142 of solenoid 83 is energized upon closing of the contacts 206 so that the table is given a quick return, this continues until dog D opens the switch S<1> and breaks the circuit to the reverse contactor. The circuit to the coil 271 of the control relay 265 is also broken so that both forward and reverse contactors remain open and the table comes to rest. The cycle may be automatically repeated by disconnecting the movable link 273 and connecting it between wires 272, 310. The spindle motor may be stopped when the table is reversed by disconnecting a link 263, and connecting a link 316. Overload relays are provided in the control circuits of both motors so that if either stops due to overload the other will also be stopped.

Abstract: 119,244. Alpha Products Co., (Assignees of Hirsch, A., and Hirsch, M.). Sept. 17, 1917, [Convention date]. Drawings to Specification Alloys ; metals, preventing oxidation of during melting.-Cerium and similar rare-earth metals and their alloys for tinder lighters &c. are melted under a protective coating of fused barium or sodium chloride or other salt inert to the metal or in an atmosphere of hydrogen and cast, at a temperature only slightly above the melting-point, in a heated mould or one with thin walls and cooled at the ordinary room temperature. The barium chloride is first melted then an alloy of cerium, lanthanum, and didymium and possibly small quantities of erbium and thorium, but with less than 10 per cent of iron, broken into lumps about 1 inch in diameter, is added. When the crucible is half full of molten metal, loose coils of iron wire 40 to 50 grams in weight are added until the alloy contains 30 per cent of iron. The temperature is raised to 1000‹ C., the mass stirred gently and then poured into an iron mould which may have its surface dusted or coated with magnesia, rolling scale, or tin plating. If the crude metal is very impure or non-homogeneous it may first be fused under purifying salt such as barium chloride and then cast into bars to be broken up, or the salt may be removed and fresh dehydrated salt added. Copper or magnesium may be added to the alloy to increase the heat of the spark.

Patent GB-703162-A (GB)
Title: Process for the separation of gases from gas mixtures and for the separate extraction of individual gases by adsorption
IPC: B01D53/08
Filed: 1950-06-19
Abstract: In a process for separating gases from gaseous mixtures wherein a solid adsorbent is passed through a vertical column in contact with the gas mixture through an adsorption zone, a fractionating zone and a desorption zone, the desorption pressure of each substance adsorbed by the absorbent is lowered in the adsorption zone to a value lower than the desorption pressure on charging the adsorbent to equilibrium in the adsorption zone.  Lowering of the desorption pressure may be effected by undercharging the adsorbent in the adsorption zone.  When the gas mixture contains only a small concentration of the gases to be separated, the adsorption zone may be larger in cross-section than the other zones.  Apparatus is shown in which the enlarged adsorption zone is either at the top or bottom of the column.  The separation may be carried out under pressure, and the expansion of the fractions removed may then be used for cooling purposes.  The gas mixture may pass transversely to the flow of adsorbent.  Fractions containing ethane and ethylene in high concentration may be obtained by contacting a hydrocarbon mixture with active carbon. Specification 703,230 is referred to.

[Class 38 (iii).] Reversing.-Switches used for connecting resistance in shunt with the field of a series motor driving, for example, a vehicle, are employed also for making connections for reverse operation. With a reversing switch 22-25 in the " forward " position, operation of a master controller 14-21 causes in succession closure of line contactors 5, 6, exclusion of steps of armature resistance 3, and connection of field shunting resistances 12, 13. With the switch 22-25 in the " reverse" position, operation of the master controller to its first position causes closure of line contactor 6 and series field shunting contactors 10, 11, the field being thus reversed, and the motor running in the reverse direction at slow speed. Further movement of the master controller may be prevented by a mechanical interlock, or an electrical interlock preventing the closure of armature resistance contactor 7 may be provided, and then further movement of the master controller cuts out two steps of armature resistance in turn to give a higher and variable reverse speed.
