Abstract: 278,387. British Thomson-Houston Co., Ltd., (Assignees of Langmuir, I.). Oct. 2 1926, [Convention date]. Addition to 223,921. Vacuum tubes; low-pressure metallic-vapour apparatus.-In a discharge tube according to the parent Specification for use as a detector and amplifier, a grid is arranged to surround the anode completely, and a negative potential is applied to the grid of such a magnitude as to fill the interstices of the grid with sheaths of positive ions, and oscillating potentials to be amplified are applied to the grid so as to separatethe sheaths. As shown, a mercury cathode 7 is connected through a battery 16 and telephone receiver 4 with the anode 11, and through a winding 6 and a battery 13 with the grid 12. The arc is maintained by an exciting eletrode 8 connected through a resistance 10 with a supply 9 of continuous current. The winding 6 is coupled with a winding 2 in the aerial, and is shunted by a tuning condenser 5. The negative potential applied to the grid is such that current passes through the device only when oscillations are superposed. In a modification, an auxiliary ring- shaped electrode is mounted above an incandescent cathode so as to maintain the vapour or gas around the cathode in a highly-ionized state, and the tube may contain mercury vapour or argon.

A detachable terminal head B, B<SP>1</SP> at each end 6, 6<SP>1</SP> of a pneumatic system for transferring articles 20 comprises a casing 10 sealingly connectible to the end 6 of a conveying conduit A by a locking mechanism, and a breech block slidably mounted on the casing 10 for movement between a top position in which the casing is sealingly closed and a bottom position in which the casing is opened and in which the block can receive an article 20. A pneumatically operated jack 30 is borne by the casing 10 and controls the displacement of the breech block, and a tube 26 facilitates supply and discharge of conveying gas to and from the casing 10 when the casing is closed by the breech block. The locking mechanism which supports the casing 10 from the conduit end 6 during its unlocked condition, comprises a system of levers and links which are spring biased into an over centre locked position, for security. The jack 30, which is spring biased into its retracted position, actuates the breech block through a fork 38 connected to the jack piston rod 36 and pivotable about the axis thereof for disengagement from the block. The supply of pressurized gas from a source 66 to the jack 30 and tube 26 is controlled by a three-position solenoid valve 68, which in an " inoperative " position prevents flow to both whereupon the jack is retracted by its spring to close the casing, in an " occupation " position permits flow to the jack whereupon the breech block is moved into the article receiving position and the tube 26 is opened to discharge through a pneumatic relay valve 70, and in a " sending " position causes the jack to be discharged to close the casing 10 and the tube 26 to be supplied with pressurized gas through the valve 70. An article 20 despatched from the head B during the "sending " condition of valve 68 cuts a photo electric beam before entering the head B<SP>1</SP> which renders the valve 68 " inoperative," and renders the valve 681 " occupied," whereby the breech block of the head B<SP>1</SP> is opened and the outside may be removed. After the solenoid valve 68<SP>1</SP> has been rendered " inoperative," the cycle may start afresh. Electrical locking lines are provided so that both solenoid valves can simultaneously only be rendered "inoperative." In a modification, Figs. 5 and 6 (not shown), the jack is pivotally mounted on the casing and operates the associated breech block through a crank lever also pivoted to the casing.
