Title: Improvements in and relating to the production and control of electron streams
IPC: H01J31/06
Filed: 1938-11-09
Abstract: 521,199. Cathode-ray tubes. HARRIES, J. H. O. Nov. 9, 1938, Nos. 32464 and 34983. [Class 39 (i)] In a beam valve such as a heavy current relay or frequency multiplier the beam is maintained by a lens system comprising an electron permeable electrode E, a deflecting electrode D at a lower steady potential than the electrode E and an accelerator electrode G2 near the cathode A. The cathode is surrounded by a shield B at near zero bias and between the grid G2 and the cathode is a negatively biassed grid G1, the wires of the grids G1, G2 being placed very close to deflect the electrons from the accelerating grid G2. The cylindrical deflecting electrode D surrounds the beam along part of its path. The permeable electrode consists of spaced rings e with segments e<SP>2</SP> carrying inwardly projecting divided wires e<SP>3</SP>. Beyond this electrode is an anti-cross-field grid F ; it consists of an annulus f<SP>1</SP> carrying wires f<SP>2</SP> and partition plates f<SP>3</SP> providing three recesses, a central one for the main carbon output anode T and side recesses for the sub-anodes T1. The electrode F is at substantially lower bias than the electrode E (1) to screen the output anode from changes in voltage of the electrodes E, Dn and (ii) to prevent cross flow of secondary electrons between the main to the sub-anodes T, T1. The main anode is at the same potential as the electrode E and the anodes at a potential between this and the potential of the electrode F. The cathode, shield B, grids G1, G2, and electrode E are supported by wires passing through the pinch H ; the wires d<SP>1</SP> to the deflecting plates pass through a side tube X ; the main anode is supported by a tungsten rod s and the sub-anodes and the electrode F by wires arranged radially to pass out through the side wall of the tube. The support rods care welded direct to the annulus f<SP>1</SP> but the rods d are welded to wires on the annulus to allow movement. According to the second Provisional Specification the electrode D may be divided into more than two sections to receive various deflection impulses ; the electrode E may have slats or perforated plates in place of the wires. The tube may work as a selfoscillator. Specifications 380,429 and 521,246 also are referred to.

Patent GB-521013-A (GB)
Title: Improvements in or relating to skip winding in mines
IPC: B66B17/04
Filed: 1938-11-09
Abstract: 521,013. Skip-hoisting in mines. INTERNATIONAL COMBUSTION, Ltd., DAVIDSON, G. W., and HERBERT, S. L. Nov. 9, 1938, No. 32519. [Class 78 (iv)] In skip winding in mines the use of hoppers at the top and bottom of the shaft is dispensed with by moving the skip out of the shaft into a position into which it can be loaded directly from tubs or a conveyer or can discharge directly on to a conveyer. The system may be worked with two skips, one of which is either being raised or lowered or unloaded while the other is being loaded, or a three-skip-system may be used in .which while one skip is being raised or lowered a second is being loaded and the third unloaded. Figs. 2 and 4 illustrate the invention as applied to a six-skip-system in which one skip is always descending the shaft, a second ascending, a third being unloaded at the top and a fourth loaded at the bottom of the shaft, while the fifth is already loaded and awaiting its turn to ascend and the sixth unloaded and awaiting its turn to descend. Fig. 4 shows the apparatus at the top of the shaft. As the wheeled skip 4 arrives in its transport cradle or cage at the top of the shaft it is pushed by a ram 34 into the position 5 on a turntable 13. The latter then rotates through a half revolution to bring the skip 4 into the discharging position 6 where it delivers to the conveyer 16 and at the same time brings the unloaded skip 6 into the position 5 from which it is moved into the cage by the ram 44, and then lowered. When it reaches the bottom of the shaft a second skip reaches the surface at position 1 and undergoes a similar cycle of movements on the turntable 12, delivering to the conveyer 17. All the rams and turntables are arranged to move in timed relation, and walls 19 on the turntables form an air seal for the shaft during the unloading operations. At the bottom of the shaft the apparatus is similar to that at the top; the ram 14, Fig. 2, pushes the skip 4 on. arrival into the position 5 on the turntable 11 whence it is rotated under the tippler 15 for loading, while the skip 1 undergoes a similar cycle of movements on the turntable 10. Fig. 6 shows the apparatus at the bottom of the shaft in a modification in which turntables are dispensed with. There are two loading stations 15 at opposite sides of the shaft 7. When the skip 1 arrives at the bottom, if a loaded skip is in position 2, the ram 14 is operated to displace 1 to the right and bring 2 into position for hoisting. The next time an empty skip arrives at 1, the ram 24 will displace it to the left and bring the original skip 1 back to hoisting position. While 1 is being lowered the companion skip 4 is being hoisted and vice versa. The apparatus at the top of the shaft is similar; two discharging stations being fitted on opposite sides of the shaft.

Title: Improvements in and relating to apparatus for recording and reproducing sound
IPC: G11B7/00
Filed: 1930-10-29
Abstract: 366,096. Optical sound recording and reproducing apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Barfield, A. R. ; 634, Lexington Avenue, Rochester, New York, U.S.A.) Oct. 29, 1930, No. 32541. Convention date, Oct. 29, 1929. [Class 40 (ii).] Apparatus for recording or reproducing sound comprises a plurality of light sources, means for directing light selectively from one of such sources on to the record film 1 through an optical system, and means responsive to a failure of the operating light source to cause light from another source to be directed on to the film. As applied to sound recording, light from either of two sources 6, 17 is reflected on to an oscillograph mirror 7 and then through an optical system so as to make a variable width record on the film 1. The optical system comprises a cylindrical lens 9, spherical lens 10, apertured screen 11, and microscope objective 14. The light from the lamps 6, 17 is reflected on to the mirror 7 by means of a mirror 16 which is adapted to be oscillated on a pivot 21 by an arm 22. The arm is operable in one direction by a spring 25 and in the opposite direction by an electromagnet comprising a solenoid 26 and plunger 27. The lamp 6 is in series with the solenoid 26, and the lamp 17 is in a circuit which is controlled by a switch 31 adapted to be operated by the plunger 27. When the lamp 6 is operating, the solenoid 26 is energized and the switch 31 is open. When the solenoid becomes de-energized owing to the failure of the lamp 6, the spring 25 effects closure of the switch 31 so as to energize the lamp 17 and also swings the mirror 16 into position for co-operating with the lamp 17.

Title: New anthraquinone dyestuffs
IPC: C09B1/52
Filed: 1934-11-14
Abstract: Anthraquinone dyes are prepared by reacting a 1-chloro- or 1-bromoanthraquinone carrying in 4-position an --NH2, --NHCH3 or --OH group with a primary amine of the benzene series carrying as nuclear substituent either an alkoxy group (C3H7O-- to C20H41O--) or an alkylthiol group C3H7S-- to C7H15S--), either starting material carrying certain substituents if desired; and then if the product is not already a sulphonic acid derivative with sufficient solubility, introducing a sulpho group by sulphonation or by replacement of a 3-halogen atom by treatment with a soluble sulphite.  Substituents which may be present in the starting materials are methyl, chloro, bromo or sulpho groups. Reaction may be effected in presence of a diluent, an acid binding agent and a copper catalyst.  The alkoxy-anilines for the process are prepared by alkylating the corresponding nitrophenols with alkyl esters of p-toluenesulphonic acid and reducing.  The alkylthioanilines are made by similar method to that used for ethylphenylsulphide (cf. Ber. 13, 1275).  In examples: (1) 1.3 - dibromo - 4 - aminoanthraquinone is condensed with dodecyloxyaniline and treated with sodium sulphite in phenol; p-butyloxyaniline or p-octyloxyaniline may be used instead; wool may be dyed with the dyestuff from a boiling bath containing cetyl sodium sulphate; (2) 1.3 - dibromo - 4 - aminoanthraquinone may be similarly condensed with 4-aminophenyl butylsulphide and sulphonated; (3) 1-chloro-4-hydroxyanthraquinone is condensed with p-dodecyloxyaniline and sulphonated with sulphuric acid and oleum mixture; using either p - isoamyloxyaniline or p - octyloxyaniline instead similar dyes are obtained, and 1-chloro-4-hydroxyanthraquinone may be replaced by 1-bromo-4-methylamino anthraquinone.  The products dye animal fibres in blue shades, fast to washing and milling, and which do not need chroming.  Specification 430,160 is referred to.
