Title: Improvements in alternating current relay
IPC: H02H11/00
Filed: 1921-02-15
Abstract: 179,677. Dehn, F. B., (Takamine Commercial Corporation). Feb. 15, 1921. Induction relays operating on phase disturbance and suitable for the protection of alternating- current motors comprise a magnetic enclosure, a disc armature on a spindle coaxial with the axis of the enclosure, and field magnets for the armature having cores parallel with the same axes. As shown in Fig. 1 applied to a shunt-connected polyphase relay, the induction-disc motor part is accommodated within the thick-walled portion 1 of the cylindrical iron casing covered by the magnetic end plate 4 and separated from the thinwalled portion 2, which contains the switch, by an integral partition 3. The induction disc 41 is mounted in proximity to the cover-plate 4 on a spindle 42 journaled in a hollow extension 20 of the partition 3. Four electromagnet cores 21 - - 24 project symmetrically and parallel with the spindle from the partition and carry windings cross-connected diagonally so that the two diagonally-opposite pairs are in separate phases. The connections are taken to a terminal board 16 forming the closing end of a lateral chamber D. The end of the spindle 42 within the chamber carries the contact arm 51 on which the bridging contact-bar 54 is mounted with some lost motion for self-aligning engagement with the fixed contacts 59, 60. The weight of the arm serves as the control to maintain the relay normally in the " off " position. The cross-connections between the coils may be in the form of metal spiders. In a modification, especially adapted for the protection of a motor against phase reversal and for preventing the motor from being wrongly connected, each core is provided with a series winding in addition to the fine wire one, and the casing is provided with terminal boards for mounting heavy current terminal sleeves for the series connections. In this form, the relay is used to close the motor circuit; a hand-operated pressbutton switch, when depressed, closes the finewire windings and brings the relay to the closed position, thereby closing the main circuit and introducing the series windings which serve to maintain the relay in the closed position when the press-button is released. The relay does not close if the phases are wrongly connected and, if closed, opens to break the motor circuit in the event of low-voltage, phase-reversal, or phase-break.

Abstract: 291,493. Midgley, A. H. Feb. 24, 1927. Thermionic amplifiers and detectors.-In a high-frequency receiver including a thermionic valve having in its anode circuit a resistance of the order of 2 megohms, means are provided for tuning the anode circuit in such a manner as to prevent leakage of electrons except through the anode resistance. Fig. 1 shows a valve which may be of the type described in Specification 280,981 in which the anode A1 is connected through a blocking condenser C1 to the grid G2 and the anode-cathode circuit Al K is tuned by the circuit I C. The inductance I and condenser C may be in series or parallel with one another and may be arranged in parallel as shown or in series with the anode resistance R. In the latter case the resistance R is shunted by a condenser. When a parallel combination is employed in parallel. with the resistance R a blocking condenser C2 is used to avoid short-circuiting the valve. Fig. 5 shows the application to a threeelectrode valve preferably having small electrodes as described in Specification 256,299. Fig. 7 shows the application to a valve having an auxiliary anode Aa in which case the auxiliary anode circuit is tuned and both anode circuits include resistances R. R2 of the order of two megohms, while the output may be taken directly from the auxiliary anode Aa. In a modification (Fig. 4 not shown) the output is through a transformer comprising the anode tuning circuit as the primary and a secondary connected to the grid of the succeeding valve. Specifications 272,294 and 275,387 also are referred to.

The supply pipe G is connected to inlet A, inlet stop valve of the radiator E to outlet C, outlet B to the inlet A of the next radiator valve, and inlet D to the radiator outlet. If the stop valve E is closed, the pressure fluid lifts valve J and passes to outlet B and thence to another radiator. Valve J closes seating Y, and any leakage presses valve H on its seating. If the stop valve E is open, fluid passes through A, C to the radiator, and the pressure of water or steam in the radiator opens valve H and presses valve J downward, so that the water may pass to discharge B. Valve J is pressed downward only when the fluid in the radiator is cooler and consequently denser than the supply, so that when the radiator is sufficiently heated it is automatically byepassed.
Patent GB-854268-A (GB)
Title: The electrothermic production of hydrogen cyanide by fluidized bed techniques
IPC: B01J8/42
Filed: 1957-02-25
Abstract: Hydrogen cyanide is produced by passing upwardly a gas comprising ammonia through a bed of electrically conductive particles so as to maintain the bed in a fluidised state and passing an electric current through the bed to heat it sufficiently, e.g. to 1300 DEG -1600 DEG C. to form hydrogen cyanide, which is recovered from the outgoing gases.  The particles may be carbon, preferably calcined fluid petroleum coke produced in a p  fluidised bed petroleum cracking process of metallurgical coke or stoker coke.  The ingoing gas may be ammonia alone or mixed with a hydrocarbon gas and may contain 1/2 -2% of carbon disulphide as a catalyst.  The ratio of moles of ammonia to atoms of carbon in the hydrocarbon gas is greater than 1:1.  When propane is used the volume ratio of ammonia to propane is between 3:1 and 5:1. When methane is used the volume ratio of ammonia to methane is between 1:1 and 5:3.  Ethane, butane, ethylene, propylene, natural gas or higher hydrocarbons may be used.  The contact time of the gas with the bed is normally less than one second, e.g. 0.1-0.5 seconds. Two parallel graphite electrodes may be immersed in the coke, or a single axial electrode is used with the wall of the container as the other electrode.  D.C. or A.C. is supplied and the formation of open arcs between the electrodes is avoided. The gas passes up into the bed through a carbon diffusion disk into the bed in a glass vessel the rate of supply being diminished once the bed is fluidised and hot.  A thermocouple is placed in a well in the bed.
