Title: Improvements in electric pulser circuits
IPC: H03K3/55
Filed: 1953-09-03
Abstract: 743,566. Pulse generator circuits. RESEARCH CORPORATION. Sept. 3, 1953 [Sept. 3, 1952], No. 24370/53. Class 40 (6). A pulse generator comprises a pulse-forming network including a capacitive element and a unidirectional switching device which periodically connects the capacitive element with a pulse transformer feeding the load circuit. Fig. 1 shows a high voltage pulse generator for modulating a magnetron 17 in which the pulse forming network 12 is charged from a D.C. source 6 via inductor 8 and diode 10 and is periodically discharged through the primary of the pulse transformer 14 when thyratron 16 is fired by a trigger pulse derived from the conventional low power pulser 22. The thyratron grid circuit impedance is kept very low, of the order, e.g. of 50-100 ohms, by feeding the trigger pulse from a non-inductive cathode load resistance 20 in the trigger pulse generator circuit via the 1 : 1 isolating transformer 21 to the grid of the thyratron 16. Damping diodes 18, 19 reduce the effect of reverse polarity pulses and any transients which may occur. Fig. 2 shows the application to an electrical precipator 24 in which high voltage pulses are applied to the central electrode 26 from the pulse transformer 14. A rotary switch 34 driven by a motor 36 switches the pulse to the spark gaps of similar sections of adjacent precipators and the motor 36 is synchronized with an alternator 38 which provides the trigger pulse for thyratron 51 in the low power pulser which fires thyratron 16 in the main pulse generating circuit. In this way the firing of thyratron 16 is synchronized with the switching of the rotaty switch 34. Thyratron 16 is of the high power type having an internal hydrogen reservoir and a heater which may be adjusted in voltage by circuit 48. A hold-off diode 46 is provided. Specification 660,328, [Group XXXV], is referred to.

Title: New vat dyestuffs containing phosphorus acid groups and processes for their manufacture and use
IPC: C07F9/12
Filed: 1963-06-19
Abstract: The invention comprises vat dyes containing "vat stable phosphorus acid group", said group being a group which is not removed by ordinary conditions of vatting in an aqueous bath, and includes those groups which form hydroxyl groups during the vatting process, e.g. halogen and -O- alkyl groups.  The dyes must contain at least two vattable groups or a single vattable system having at least 5 condensed rings.  The phosphorus acid group may be attached to the main dye molecule by means of a carbon or oxygen bridge, or may be directly attached.  The phosphorus acid group may be introduced into the vat dye by combining intermediates containing the group or by direct treatment of the dye with phosphorus oxychloride, oxybromide, ortho and polyphosphoric acids, phosphorus pentoxide, pentasulphide, thiotrichloride and thiotribromide, metal phosphites and phosphorous acid esters. In particular acylating agents which contain the phosphoric acid group are combined with aminoanthraquinone derivatives, the acylating group being phosphato acetic acid chlorides.  Derivatives of cyanuric chloride are specified as acylating agents.  Acylation is advantageously carried out in nitrobenzene, chlorobenzene or o-dichlorobenzene, but may be done in aqueous media containing an acid-binding agent.  The phosphoric acid group may be introduced before ring closure to form a carbazole, oxdiazole or acridone dyestuff.  The dyes obtained may contain water solubilizing groups or be sulphonated to render them water-soluble. In examples para- and meta-chloroformylphenyl dichlorophosphate, 3,5-dichloroformylphenyl-dichlorophosphate, 4 - b  - acetoxy - ethoxy-benzoyl chloride (mixtures of thionyl chloride with the corresponding acid), are used as acylating agents, in the last case the acetoxy group is hydrolysed off and followed by treatment with polyphosphoric acid, the acid chloride of para-carboxylbenzylacetate is used in the same way as the 4-b -acetoxy-ethoxy benzoyl chloride. Also used as acylating agents are the acid chlorides of o,o1-di-para-carboxyphenyl phosphoric acid, para-carboxyphenyl phosphonic acid, para-carboxybenzyl phosphoric acid, 4,41-dicarboxy-diphenyl phosphonic acid and phosphonic acetic acid trichloride. The amines combined with the above agents are amino derivatives of anthraquinone, thiazoleanthraquinone, dianthrimide-carbazole, benzanthrone-anthraquinone, phthaloyl-acridone, thioindigo, acedianthrone, dibenzanthrone, perylene - tetracarboxylic acid imides and dianthrimide.ALSO:In Examples 1 and 2 cotton is dyed with vat dyes containing a "stable phosphorus acid group" such a group is derived from any oxyacid of phosphorus and is not removed under the vatting conditions.  Normal vatting procedures are employed.

Filed: 1920-08-23
Abstract: 151,976. Metropolitan-Vickers Electrical Co., (Assignees of Schmidt, H. E.). Sept. 30, 1919, [Convention date]. Starting, automatic; regulating or controlling action; overflow arrangements.-Relates to apparatus for withdrawing condensate from a steam condenser and consists in an overflow return to the condenser controlled by a valve subject to control in part by the discharge pressure of the ejector, the ejector being either of the single-full bore nozzle type, or having an annular nozzle for low-pressure inducing-fluid and a central nozzle for high-pressure fluid automatically regulated according to the quantity of con densate for withdrawal, in which case overflow is additionally controlled by the high-pressure supply. The ejector is thus self-starting and proof against breaking-back. The steam nozzle 9, Fig. 1, of the ejector is situated in the hot-well 7 of the condenser 5, the diffuser 10 being below the normal condensate level, and having the usual non-return check valve 12. In the overflow pipe 13 leading back to the condenser is a valve 14 subject to the combined control.of the diffuser pressure acting upon the base of the valve, of a spring 17, and of the delivery pressure of the ejector which has access through a passage 18 to a cylinder containing a piston 15 upon the valve stem. The parts are so designed that if the pressure in the discharge pipe be at least sufficient to overcome the pressure of the atmosphere, the overflow valve remains closed; it is otherwise when the ejector is starting, or when the condensate to be ejected is less than the minimum capacity of the ejector. Fig. 2 shows a condensate ejector 20 consisting of an annular nozzle 22, induced-fluid conduit 21, combining- tube 23, and diffuser 24. There is also a central nozzle 26, independent supplies 27, 28 of inducing-fluid being provided, at different pressures. From the overflow chamber 25 communication is established with the condenser 19 when a valve 32 in the overflow pipe 31 is open, the condition for this being determined by the overflow pressure upon the face of the valve, the strength of a spring 43, and the pressures in the central high-pressure inducing-fluid nozzle 28 and in the discharge tube 24 respectively, as communicated to differential pistons 33, 34 on the valve stem. Longitudinal expansion and contraction of the condensate pipe 21 as the amount of condensate varies is arranged to actuate a control valve 39 in the inducing-fluid conduit for the central highpressure nozzle so that increased motive fluid may be supplied when condensation is rapid.
