Title: Tertiary phosphines and methods of preparing same
IPC: C07F9/50
Filed: 1962-05-11
Abstract: The invention comprises a tertiary phosphine of the formula: <FORM:0956221/C2/1> wherein R is an aryl or substituted aryl radical, R1 and R2 each represent a substituted or unsubstituted branched or straight chain alkyl or alkenyl radical having up to 18 carbon atoms, a substituted or unsubstituted cycloalkyl radical or a substituted or unsubstituted aryl radical. They may be obtained by reacting a secondary phosphine of the formula:  R1R2PH with an isocyanate of the formula RNCO.  The reaction is preferably carried out in the presence of an inert organic solvent, e.g. an aromatic hydrocarbon, an ether or a halogenated hydrocarbon, e.g. xylene, benzene, toluene, tetrahydrofuran, dioxane, chlorbenzene or chloroform, and may be effected at atmospheric or higher or lower pressure.  Suitable temperatures are from -15 DEG C. to 200 DEG C., preferably 30 to 110 DEG C. and an organic base may be used as catalyst, e.g. pentamethylguanidine or trialkylamines having 1 to 4 carbon atoms in the alkyl group.  Typical substituents for the radicals R1 and R2 are alkoxy radicals containing up to 6 carbon atoms, phenyl, halogen, and cyano and typical substituents for the radical R are C1-6 alkoxy, halogen and nitro groups.  The products are useful as fire retardants for cotton cloth (see Division D1).ALSO:A carbamoyl-substituted tertiary phosphine of the formula:  <FORM:0956221/D1-D2/1> wherein R is an aryl or substituted aryl radical, R1 and R2 each represent a substituted or unsubstituted branched or straight chain alkyl or alkenyl radical having up to 18 carbon atoms, a substituted or unsubstituted cycloalkyl radical or a substituted or unsubstituted aryl radical (see Division C2) may be used as fire retardants for cotton cloth, e.g. by dipping the cotton cloth in a solution of the substituted phosphine.  The radical R may be substituted by alkyl, alkoxy radicals containing up to 6 carbon atoms, nitro groups or halogen atoms and the radicals R1 and R2 may be substituted by alkoxy radicals containing up to 6 carbon atoms, phenyl, halogen or cyano.

Title: Improvements in or relating to electrical signalling systems
IPC: G08C19/22
Filed: 1943-11-08
Abstract: 576,845. Electric selective signalling. DRYSDALE, L. H., and SQUIRES, M. Nov. 8, 1943, No. 18522. [Class 40 (i)] In a system in which a signal of variable duration causes an impulse generator at the receiver to step a selecting switch for the duration of the signal, in order to counteract the effect of fading and at the same time to guard against spurious signals, an operation takes place after the signal has been received for a certain time by which a subsequent break in the transmission does not disable the impulse generator unless it lasts for longer than a predetermined time. A selective system operating over a radio link is shown in which the radio transmitter TT is modulated on a frequency X for a period dependent on the operated one of a set of keys KA... KK, and on a frequency Y momentarily at the beginning of the period and shortly after its termination. Relay SA controlled by a start key KS connects up the X and Y frequency oscillators and starts an impulse-generating relay PU to step the switch AW, the Y frequency being cut off when the switch moves off-normal. Relays XA, YA at the receiver respond to the X and Y frequencies and their simultaneous operation starts an impulse-generating relay IP to step the switch BW, the circuit being maintained by relay XB until the switch reaches position 3, and then by relay ST. If the X frequency stops before the switch reaches position 3, relay HA pulls up, disconnects IP and makes a homing circuit for the switch. If the X frequency stops after this time, impulses are delivered to counting relays U... M as long as XA is back, but the operation of the switch BW is unaffected unless the break persists long enough for relay M to energise. At the transmitter, assuming for example that key KE is operated, relay T pulls up in position 7 of the switch AW and cuts off the X frequency, and relay TA pulls up in position 9 and the Y frequency is sent during the release period of relay SA. The switch AW then goes home. On the cessation of the X frequency signal, relay M energises after two more impulses from relay IP, and since relay YA is operated by the Y frequency at this time, ground is connected to the selected wire of the set SD 1 ... 10. The release of relay ST sends the switch BW home. Instead of the self-interrupting relays PU, IP, thermionic oscillators may be used for generating impulses.

Abstract: 242,698. Alexander, A. E., (Signal Engineering & Manufacturing Co.). Aug. 11, 1924. Bell cases or covers; bell-operating mechanism, electric; bell sounding-members, supports for.- A bell of the solenoid and plunger type comprises a casting 28 which serves as a yoke and housing for the solenoid 24, a guide and support for the plunger 49 and a support for the sounding member 55, the casting also constituting a over for a terminal box 12. An additional threaded hole 58 in the arm 48<1> of the casting 28 provides for the use of a larger sounding member with the same solenoid and with the upper edge of the sounding member in the same position relative to the top of the plunger tube 53. In order that the bell may be used as a single-stroke bell with alternating-current, the lower portion 57 of the plunger is cut away so that after one blow has been struck the asymmetrical pull on the plunger will cause a braking of its movement and so prevent any further strokes. When a number of such alternating current bells are employed in series, the plungers are made heavy and are normally well outside the centre of the solenoid field so that all will have moved appreciably before any one has moved sufficiently to constitute an effective choke for the others. The Specification also refers to the previous use of condensers or very light plungers to prevent this mutual-choking action. The constructions of bells described are similar to those described in Specification 220,940. Specification 242,699 also is referred to.

Title: Improvements in and relating to catalytic conversion plant for the continuous generation of gases from hydrocarbons
IPC: B01J8/06
Filed: 1961-05-26
Abstract: <FORM:0954844/C3/1> A catalytic conversion plant for the continuous generation of gases from hydrocarbons comprises a conversion element 1, a heat exchanger 2, an air preheater 3, and a burner 4, formed as a unit which is detachably connected with a steam generator 5 by means of a flange connection 6.  Heated air leaving the preheater 3 by outlet 24 is mixed with steam discharged at 33 from steam generator 5 and the hydrocarbon is fed into the mixture.  The resultant mixture enters the apparatus by inlet 15 through the annulus of the heat exchanger 2 and is preheated to 450 DEG  to 500 DEG  C. by the outflowing conversion gases in pipes 16; the preheated mixture then enters the concentric annular spaces 10 and 11, formed by the concentric pipes 7, 8, and 9 which contain the conversion catalyst, and the converted gases leave through pipes 16.  The heating is effected by burning a suitable fuel with air in the burner 4; the hot flue gases formed circulate through the apparatus and are used to heat the catalyst in the conversion element 1, to preheat the air which circulates through the annulus 3, and to vaporize the water in steam generator 5.  The catalyst temperatures are from 750 DEG  to 900 DEG  C. The pipes constituting the conversion element may be ribbed or corrugated in order to increase the heating surface.
