Title: Improved means for testing and selecting electrical circuits, particularly in automatic telephone systems
IPC: H04Q3/00
Filed: 1942-03-03
Abstract: 549,324. Automatic exchange systems. WESTERN ELECTRIC CO., Inc. March 3, 1942, No. 2796. Convention date, Feb. 8, 1941. [Class 40 (iv)] A testing arrangement common to a group of switches comprises a number of discharge-tubes equal to the number of outlets and means for applying a starting potential to the tubes in succession. In the cross-bar stage shown, a switch such as 102 is connected by known means to the common apparatus 200 in which 284 pulls up to connect battery 286 through a common resistance 285 to the starting cathodes 231 &c. The starting anodes have ionizing potential applied to them in succession from apparatus 281 but this is without effect on the main gaps of tubes associated with busy lines since these have their grids grounded over the test wires. As soon as the starting gap of a tube associated with an idle line is ionized however, the discharge spreads to the main anode and the anode relay causes the seizure of the line. The potential drop in 285 due to the main discharge prevents ionization of the starting gaps of any other tubes. In a modification, Fig. 3 (not shown), the testing tubes, instead of energizing relays directly, cause discharges in auxiliary relay-controlling tubes. Specification 466,986 is referred to.

Abstract: 506,849. Cracking and reforming oils. UNIVERSAL OIL-PRODUCTS CO. Feb. 1, 1938, No. 3146. Convention date, June 30, 1937. [Class 32] In a process.for cracking and reforming oils comprising a distillate stock consisting substantially of gasoline of low anti-knock value, the oils are cracked and reformed in presence of gaseous hydrocarbons and after immediate cooling to arrest further conversion the products formed are fractionated to, separate gasoline of required anti-knock value, which is stabilized, the rich gases thus released being absorbed in an oil which is then subjected, together with the absorbed gases, to the cracking step. Charging stock is fed by a pump to an absorption tower 10 and together with the gases thus absorbed is reformed in a coil 7. The products are cooled to arrest further reaction by introducing cooling oils through line 20, 22, and are then separated into vapours and liquid fractions in a separator 19, to which also cooling oil may be admitted' through line 24. The vapours are fractionated in a tower 30 into (a) products of desired endpoint which are recovered through line 63 and condenser 65 and collected in a receiver 68, where they are separated from gases which aro passed through line 83 into absorption tower 10 ; (b) an intermediate light fraction which is withdrawn through line 45, reboiled in tower 47 to remove absorbed gases which are returned through line 49, and fed through cooler 58 as absorption'oil to tower 10 ; alternatively this fraction may be fed through lines 55, 42 to mix with the recycle stock from tower 30 ; and (c) heavy recycle stock which is removed from the bottom of tower 30 and fed through lines 31, 34, 36, 14 to the coil 7. Part of this stock may be withdrawn through line 35 or fed through cooler 42 as absorber oil to tower 10. The gasoline from separator 68 is cooled in heatexchanger 77 and stabilized in tower 80, the stabilized product being withdrawn through line 99 while the gases.evolved are led off through line 81 and mixed with the gases passing through line 83 to the tower 10. A part of the; light gasoline fraction may be removed from tower 30 through line 69, 61 and mixed with the stabilized final product.

Automatic-feed weighers.- In machines for bagging and simultaneously weighing provender, and of the type described in Specifications 1123/12 and 105,615, [Class 5 (ii), Housing &c. animals], the flow of chaff &c. from one leg of the feed-shoot is shut off and the flow diverted into the other leg as soon as a bag has been filled with the predetermined weight of the material, by means of a pivoted overbalance weight-lever acting in conjunction with a swinging pendulum on the axle of the control valve and a pair of latch-levers connected to the arms of the weighing-machine. The pendulum d on the axle c of the valve b carries near its lower end a weight-lever e pivoted at e' between two stops d<1>. Latchlevers f pivoted at f' on the outside of the shoot a are each weighted at one end f<2> to engage normally a pin d<2>, and are connected at the other end by a cord f<3> to a lug g<1> on the collar g from which the bag h is suspended. A sliding lock-bolt m supported in guides on the front of the machine is provided to lock either arm j of the weighing-machine when required. The bolt m is actuated by means of a thumb-piece n and is limited in its traverse by a stop p. When a charged bag h overbalances the weights o on the arm j, the cord f<3> releases the pendulum d from the lever f, whereupon the weight-lever e swings the pendulum over until it is latched by the opposite lever f, thereby reversing the valve b. The attendant then reverses the position of the weight-lever e on the pendulum, as indicated in dotted lines, to ensure sufficient momentum to carry the, pendulum back when the other bag is filled.
