Title: Electronic discharge tube
IPC: H01J17/48
Filed: 1951-06-19
Abstract: 696,109. Multi-gap cold-cathode tubes. STANDARD TELEPHONES & CABLES, Ltd. June 19, 1951 [June 30, 1950], No. 14496/51. Class 39(i) [Also in Group XIX] The priming coupling between successive gaps in a cold cathode gas-filled sequence discharge tube is made greater in one direction along the array of gaps than in the reverse direction by masking means which restrict the spread of cathode glow over the surface of individual cathodes to differently sized adjacent areas of the cathode surface along the line of the array. The tube, Fig. 1, comprises storage cathodes 1, 2, 3, 4 and 5, and transfer cathodes 6, 7, 8 and 9 both in the form of rectangular metallic plates, a metallic shielding plate 10 having rectangular apertures such as 11 and 12 joined by a slot 13, and a metallic plate anode 14, separated by mica plates 15, 16, 17, 18 and 19. Mica plates 17 and 18 have slots 20 and 21 respectively, opposite the slot 13 in the shielding plate 10. Glass rods such as 30 and 31 fit into holes 22, 23, 24, 25, 26, 27, 28, and 29 to locate the electrodes and mica plates between two frames 32 and 33 which are clamped together by means of bolts or rivets in the holes 34, 35, 36 and 37. The disposition of the apertures in the shielding plate with respect to the storage and transfer cathodes is shown in Fig. 2, which shows two storage cathodes 38 and 39 and two transfer cathodes 40 and 41. Rectangular apertures 42 and 43 opposite the right-hand portions of the storage cathodes, and smaller rectangular apertures 44 and 45 opposite the right-hand portions of the transfer cathodes are connected by slots 46 and 47. The current passing through the tube and the electrode dimensions are such that the glow discharge concentrates in the larger rectangular aperture, so that a discharge from cathode 38 will concentrate in aperture 42 and the coupling to transfer electrode 41 will be greater than the coupling to transfer electrode 40 which is farther away. The tube is connected in a circuit (see Group XIX) whereby the transfer cathodes are biased positively with respect to the storage cathodes and are connected in common to a source of negative pulses. The electrode dimensions and the value of a resistor in the anode circuit are chosen so that only one discharge can be sustained at a time. The discharge is stepped one storage cathode along the array for each pulse applied to the transfer cathodes. In an alternative arrangement the storage cathodes are trapezoidal in shape and are arranged in a circle between transfer cathodes constituted by teeth of trapezoidal shape provided around the edge of a disc. Two coplanar concentric shielding plates provide apertures of trapezoidal shape connected by slots. Specifications 639,827, 691,901 and 692,415 are referred to.

Title: Improvements in electromagnetically-actuated means for operating switch mechanism oftramway or like systems
IPC: H01H51/12
Filed: 1934-05-22
Abstract: 436,748. Operating tramway&c. points. FOREST CITY ELECTRIC CO., Ltd., and QUILLIAM, S. T., 4, Longford Road, Stretford, near Manchester. May 22, 1934, No. 15198. [Classes 104 (i) and 104 (iii)] [See also Group XXXVII] Electromagnetic means for operating the switch mechanism of tramway or like systems comprise a pair of electromagnets or solenoids 8, 9 adapted to be energized alternatively to move a frog-lever or like member in one or the other direction, in combination with a spring- controlled pivoted contactor 10 movable over a dead-centre by the energized electromagnet or solenoid to break the circuit of the latter and prepare a circuit for the other electromagnet or solenoid. In the arrangement shown, for setting an overhead frog on the trolley wires of a traction system in the same direction as the rail switch beneath, the latter is operated by energizing one or other of a pair of solenoids 1, 2. If the solenoid 1 is energized, the plunger 3 is drawn to the left, and a circuit is completed from the trolley wire 10y through the contactor 10 and coil 8 to earth through the contact 4. The plunger 17 is thereby moved to the left and actuates the lever 16 connected to the frog switch, the contactor 10 being at the same time moved from the contact 12 connected to the coil 8 to the contact 11 connected to the coil 9. The coil 8 is thereby de-energized and a circuit is prepared for the coil 9, the latter circuit being completed through the contact 5 when the solenoid 2 is energized to move the rail switch in the opposite direction. In a modified construction, the plunger 17 is replaced by a pivoted armature and the coils 8, 9 are provided with cores. In another arrangement a relay is employed which causes the frog switch to be moved in one or the other direction according to whether a car is or is not drawing current from the overhead line.
Patent GB-693762-A (GB)
Title: Improvements in or relating to the purification of vinyl ethers
Filed: 1950-06-19
Abstract: In the preparation of a vinyl ether by vinylating an alcohol of the C4-C8 range the alcohol content of a mixture containing the vinyl ether and its corresponding alcohol is reduced by treating the mixture with an aqueous solution of a salt of an alkali or alkaline earth metal with an acid of the formula CnH2nO2, where n is 3-8, or with benzoic acid, or with an aromatic acid of formula C8H8O2, said solution containing at least 20 per cent by weight of the salt, to form a solution of the alcohol therein, and subsequently separating the alcohol solution so formed.  The mixture treated may be the crude product obtained on vinylation but it is p  preferable to distil such product to obtain a mixture of vinyl ether and alcohol having a vinyl ether content substantially equal to that corresponding to the azeotrope and then to treat such mixture with the solvent.  The treatment may be carried out batchwise or in a continuous manner.  In the latter case the solvent can be fed continuously near to the top of a tower containing packing material such as Raschig rings and the mixture fed continuously near the bottom of the tower.  Purified vinyl ether is continuously withdrawn from the top of the tower whilst solvent charged with alcohol and a small amount of vinyl ether is continuously withdrawn from the bottom of the tower and its alcohol and vinyl ether content recovered by distillation.  It is an advantage in such a counter-current process to use a small amount of a surface-active agent such as an alkyl aryl sulphonate, a long-chain alkyl sulphate or an alkyl aryl polyglycol ether to assist in the wetting of the packing by the solvent and the mixing of the solvent and the vinyl ether.  Examples describe the purification of a mixture of isoamyl vinyl ether and isoamyl alcohol by batchwise treatment with: (1) 8N aqueous sodium propionate; (2) 5.5N aqueous sodium butyrate; (3) a 20 per cent aqueous solution of calcium butyrate; (4) an aqueous solution containing 35 per cent of barium butyrate; (5) 6.4N aqueous potassium butyrate; (6) 6.3N aqueous sodium isobutyrate; (7) 2.4N aqueous sodium caprylate; and (8) a saturated aqueous solution of sodium benzoate.  An example is also given in which a mixture of 2-ethylbutyl vinyl ether and 2-ethylbutyl alcohol is purified by batchwise treatment with 5N aqueous butyrate.  The use of potassium isobutyrate is also mentioned.  Specification 669,071 is referred to.
