Title: Improvements relating to image-reproducing or picture cathode ray tubes
IPC: H01J29/80
Filed: 1956-06-06
Abstract: 835,117. Cathode ray tubes. GENERAL ELECTRIC CO. June 6, 1956 [June 7, 1955], No. 17497/56. Class 39(1). In colour television picture tubes where the screen includes a colour grid and a screen electrode further potential applying electrodes are provided to correct for non-uniform fields, e.g. at the periphery, between the grid and the screen electrode. The colour grid 31, Fig. 4, is parallel to the screen 25 having a conductive layer 27 and phosphor layer 26, the uncorrected electric field between these two electrodes being shown by the lines 33, 35. An electron imping- ing at the periphery of the screen 25 would, in this uncorrected field, strike the screen at point 41 instead of at the desired point 37 thereby giving colour disturbance at the edges of the field. The field is corrected according to the invention by means such as an electrode member 42, Fig. 1, mounted around the greater part or the whole of the periphery of the screen 42 so that the electric field follows the lines 33, 45 and the electron beam follows the path 46. The member 42 may be secured to the screen 25 by means of clips 43. If the colour grid 31 is of smaller dimensions than the screen 25 then the field-correcting electrodes are mounted on the periphery of the colour grid, if both the screen and grid are of equal size then correcting electrodes may be mounted on both their peripheries. The correcting field may be established by a rod like conductor clipped around the periphery of the grid or screen, or the screen may have peripheral ridges on its glass base over which is continued the conductive layer 27 in order to correct the peripheral field.

Abstract: 166,523. Bayerische Elektrizitõts- Xndustrie Rott & Co. July 15, 1920, [Convention date]. Automatic circuitbreakers. - A thermally controlled cut-out switch is constructed so that the circuit cannot be closed until the thermally actuated locking mechanism is engaged and the operating pushbutton has been released. A hollow disc f of insulating material carries a contact g co-operating with a fixed contact spring v. The disc is turned upon its pivot n by a push-button i connected to a spring-controlled contact-stirrup q which tends to engage a tail piece g<1> of the contact g. The contactstirrup q operates the disc, which is friction-controlled on the pivot n, through a lost-motion device between an arm which carries the stirrup and a slot in the side of the disc through which it passes. The pressure upon the button i to reset the switch consequently first disconnects the stirrup from the tail piece g<1> and then turns the disc to engage the contacts g, v in which position it is retained by the nose r of the thermal locking-means e, e<1>. The circuit is not clcsed until the push-button is released and the stirrup and tail piece g<1> have come into contact- Should the thermal elements not have returned to locking position, the disc will fly back under the influence of the stirrup. The cut-out is mounted in a porcelain casing with screw and pin terminals w, c. According to the Specification as open to inspection under Sect. 91 (3) (a) spark-quenching means may be provided on the disc f. This subject-matter does not appear to the Specification as accepted.

Filed: 1963-05-07
Abstract: The invention comprises (a) caprimidyl sulphate, and (b) a process for the preparation of lactams which comprises contacting an alicyclic ketoxime with sulphur trioxide complexed with a phosphoryl-containing compound or a sulphur trioxide-stable ether for a sufficient time to rearrange the oxime to the imidyl sulphate, hydrolysing the imidyl sulphat, and recovering the lactam product. The alicyclic ketoximes and sulphur trioxide complex are preferably contacted in the liquid phase under approximately atmospheric pressure, at temperatures not exceeding room temperature in the presence of an inert solvent.  The molar proportion of sulphur trioxide to oxime should be about 1 or more. The imidyl sulphate may be hydrolysed by mixing with at least a stoichiometric amount of water at below room temperature.  The molar ratio of sulphur trioxide to complexing agent is preferably 1: 1.  The sulphur trioxide complex is prepared by mixing about equimolar amounts of sulphur trioxide and the complexing agent in a suitable inert solvent at temperatures up to 50 DEG  C. and atmospheric pressure.  Any phosphoryl-containing compounds, e.g. pyrophosphates, phosphates, phosphonates or phosphinates, can be utilized to make the complex, phosphates, especially trialkyl phosphates wherein the number of carbon atoms in each alkyl group is 1-4, being preferred.  When the phosphoryl-containing compound contains hydrogen, it is necessary to u e an extra mole of SO3 to react with this prior to forming a complex.  Examples illustrate the use of a complex containing triethyl phosphate, tributyl phosphate, dimethyl ethyl phosphinate and triethyl phosphonate.
