[Class 39 (i).] A metallic fluorescent screen 8, deflecting plates 10, 11, anode 3 and a directly - heated cathode, together with its focusing cylinder 1, are assembled to form a rigid structure prior to mounting on the pinch. The anode 3 is secured through a mica sheet to the cylinder 1 and the screen 8 is secured to the electron gun through rods 5, 6 and mica pieces 7. The rod 5 together with the deflecting plate 10 is insulated from the screen and from the anode by mica pieces 7, 9, but the rod 6, which is bent as shown, is in electrical connection therewith. The deflecting plate 11 is suitably curved to obtain greater sensitivity and is in electrical connection with the screen and with the anode. The structure is mounted through rods 12, 13 on the pinch in an inclined position so that the screen is nearly parallel to the longitudinal axis of the tube.

[Also in Division F2] The sealing means for the stand pipe of a nuclear reactor pressure vessel includes a piston and cylinder assembly with mutually opposed steps in their cylindrical surfaces, and a sealing ring groove 22 at one of the steps with a sealing ring 26 in the groove 22, the sealing ring being adapted to make a face seal in contact with the step, and a piston seal with the cylindrical surface when not in contact with the step. The cylinder or casing 2 is stepped to provide a narrow inclined face 12 and a limit stop formed by an inclined face 16, the piston or closure member 18 having a matching inclined locating surface 20, the ring 26 being lightly pinched between the top 30 of the groove 22 and the face 12. When the closure member 18 is raised by internal pressure to its upper limit as in Fig. 2 (not shown), the ring 26 moves up the face 12 and is expanded to act as a piston seal whereas in Fig. 1 the ring acts as a face seal. The angle of the face 12 may be varied from 60‹ (Fig. 4, not shown) to 30‹ (Fig. 5, not shown). This face may also be concave (Fig. 6, not shown) or convex (Fig. 7, not shown).

Filed: 1943-06-16
Abstract: 578,309. Treating liquids with gases. DIXON, O., G., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 16, 1943, No. 9637. Drawings to Specification. [Class 55 (ii)] Gases or vapours are treated with liquids in a column packed with hollow bodies of woven material the apertures in which are sealed under operating conditions, the column first being flooded with liquid so as to seal the apertures and then during deflooding and throughout the treatment, liquid is introduced at the top at a rate sufficient to maintain the apertures sealed. Flooding is effected either by (a) causing a holdup of liquid at the bottom as by means of an adjustable orifice, or in the case of distillation apparatus, (b) causing liquid in the column or from the boiler to ascend the column by expansion and boiling or (c) isolating the column, filling it with cold liquid and during heating of the boiler, withdrawing liquid from the bottom of the column or the boiler and returning it to the top until sufficient reflux liquid is passing down to maintain the apertures sealed. The filling bodies may be made from wire gauze, perforated sheet of metal or synthetic resins or woven textiles, asbestos slag wool or glass wool. Preferably a wire gauze is used having not less than 30 wires per in. spaced apart by not more than .022 in., and the distance between adjacent parallel wires is preferably between .0050 and .0075 in. The bodies may comprise hollow cylinders with a longitudinal gap in their walls and one or more internal longitudinal partitions. Their length and maximum width should not exceed  in. The column may be random packed or the bodies arranged in a regular pattern, the ratio of the smallest cross-sectional dimension of the column to the greatest dimension of the bodies being not less than 4 to 1. Specification 536,552 is referred to.

Abstract: <PICT:0493446/III/1> Steam or other vapour is condensed by impinging an unbroken column of liquid 17 from a pipe 16 at an angle against a flat, elongated baffle 18 extending wholly or partly across a casing 8 through which the vapour flows, so as to form an unbroken liquid sheet 22 extending to the casing wall.  The baffle may be rectangular and has an angular deflecting lip 20 on its edges.  The casing contains several baffles, and the liquid impinges on either or both sides of each baffle.  The liquid and vapour pass in the same or opposite directions.  The baffle has an aperture 61 near each end, through which liquid flows on to the wall.  The liquid sheet may be directed downwardly and flows down the wall, being deflected therefrom by a ring 26 above the gas inlet 14 to flow in a stream 27 to a water outlet 10.  A baffle 28 breaks the stream 27.  Reference has been directed by the Comptroller to Specification 449,652, [Group XII].

Abstract: 160,672. Parker, J. April 7, 1920. Casings, foundations, and supports; motors, gcaring for.-An electric motor 1 or other prime mover drives a centrifugal machine 8 through a hollow power shaft 3 and an inner shaft 4 longitudinally movable in the outer shaft so that when the shaft 4 is retracted, as in Fig. 4, the arms 6 at its ends are disengaged from clutch elements 7 on the driven machine. In this position the motor may be readily moved from its seating horizontally for inspecting either the motor or the machine. Rotational engagement of the shafts is effected by a feather 16 or a dog or friction clutch at the upper end of the shafts, or the shaft 4 may be of square or other angular section, the outer shaft being similarly bored. Alternatively, a solid shaft may be employed so arranged as to rotate with and slide through the armature. The shaft 4 is raised by means of a hook or tool inserted at 22, and it may be held in the raised position by a bar which is passed through a hole 23 and rests on the top of the journal box 2. The casing member 1<a> of the motor is pivoted at 11 on the post 10 in the supporting member 9 so that when the shaft is raised and the bolt 13 is removed, the motor casing may be swung horizontally for inspection of the enclosed parts. By means of a stud 15 which bears on the post 10, the motor may be slightly raised prior to swinging whereby friction between the members 1<a>, 9 is eliminated.

Class 38(5) In order to avoid a varying temperature differential between the limits of the range of adjustment of a bimetal-operated switch, the bimetal member or members are mounted in the same plane as the fixed contact member which is acted on by the range adjustment means at a distance from its support point equal to the effective length of the bimetal member or members. As shown, the fixed contact 3 is carried by a strip 2 mounted at 2A and lying between two bimetals 9, 10 carrying an insulating bridge 11 and connected by a curved arm 12. The bridge 11 carries the movable contact 5 which is connected to a terminal 13 by flexible strips 6. The arm 12 and the end of strip 2 are connected by a U-shaped snap spring 8. The adjustment means comprises a threaded sleeve 15'carrying a screw 17 supporting an insulating button 4 which bears on the strip 2. The contact gap is adjustable by screw-spring device 19.
