Tertiary phosphines are prepared by reacting a phosphoroxo compound of the formula wherein R 1 , R 2  and R 3  are similar or dissimilar substituted or unsubstituted hydrocarbon groups, either R 2  or R 3  optionally forming a ring with R 1 , with a silicon compound containing at least one Si-H bond and at least one Sihalogen bond in the presence of a tertiary amine. Specified substituents in R 1 , R 2  and R 3  are amino and alkoxy groups. The reaction is effected at elevated temperatures, preferably between 70‹ and 250‹ C., and preferably in the presence of an inert organic solvent, e.g. naphthalene, benzene, toluene, glycol diethyl ether, diethylene glycol dimethyl ether and diphenyl ether and a pressure of from 20 to 200 atm. gauge or more may be used. The silicon compound is preferably used in an amount such that 0À7-1À5 hydrogen atoms bound to silicon are available for each oxygen atom bound to phosphorus and preferably 0À8-1À7 mols. of tertiary amine are used per mole of phosphine oxide. Specified silicon compounds are phenyl dichlorosilane, ethyl dibromo silane, ethyl dichlorosilane, diethyl chlorosilane, ethoxy dichlorosilane, diethoxy chlorosilane and mono-, di- and tri-ehlorosilanes, and specified tertiary amines are trimethyl-, triethyl- or triisopropyl-amine, dimethyl aniline, pyridine and alkyl pyridines such as lutinine, α- or #-collidine, picoline and 3,5-dimethyl-4-ethyl pyridine. Specified tertiary phosphine products are triphenyl-, tricyclohexyl-, tri-n-butyl- and tri-p-methoxyphenyl phosphines. In one of the examples a mixture of tricyclohexyl phosphine oxide, triethylamine and trichlorosilane is refluxed in benzene, NaOH solution is added and the organic phase is separated and mixed with CS 2  to form a tricyclohexyl phosphine/CS 2 adduct from which the free phosphine may be obtained by adding an alcohol, e.g. methanol.

Abstract: 1,228,563. Coalescing cartridge. PUROLATOR Inc. 26 Feb., 1969 [15 March, 1968], No.10275/69. Heading BID. An annular, outward-flow cartridge which coalesces entrained water, in a stream of hydrocarbon fuel, into uniformly sized drops to facilitate subsequent gravity separation (Fig. 1, not shown), comprises an inner section of resinated glass fibres 26, an intermediate section of non-resinated glass fibres 24 and an outer section comprising glass fibres resinated in certain regions 23 and non-resinated in regions 24', which form outwardly converging extensions of section 24, ending in areas 25 on the outer surface, defined between adjacent overlapping regions 23 (Fig. 4, not shown). The cartridge is made by impregnating the inner surface and restricted areas of the outer surface of a preformed glass fibre annulus with resin, or by impregnating both surfaces completely, cutting out parts of the outer surface and inserting non-resinated glass fibres in their place. In use (Fig. 1), the inner section 26, whose inner surface may be extended by slots or pits, captures solid particles and initiates coalescence, which is continued by the hydrophilic glass fibres 24. Since resinated glass fibres are hydrophobic, water droplets concentrate in regions 24 and 24', whence they emerge through areas 25. The cartridge is surrounded by a mesh screen (16) through which the fuel passes to the outlet (14) of an enclosing housing, while the water falls to a sump 18.

Abstract: 1,230,201. Interference suppression in television receivers; limiters; automatic gain control. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 22 Oct., 1968 [25 Oct., 1967], No. 50010/68. Headings H4L, H4F, H3Q, H3T and H3W. In a circuit for suppressing noise in a T.V. receiver of the type disclosed in Specification 800,146, wherein noise signals are extracted from the detected video signal by selecting a band of signal frequencies higher than the 20th harmonic of the line scan frequency which are passed via an anode bend detector to be utilized for example, to gate the sync. pulse separator, a biased diode co-operates with the selecting means so that noise pulses above a predetermined level are selected by this diode to be utilized as above. This enables the noise suppression circuit to remain operative when overdrive of preceding amplifier circuits due to noise pulses takes place. As shown in Fig. 1, the negative modulation T.V. signal from I.F. transformer 1 is supplied via the normal detector 2 to a video frequency amplifier 5. Resistors 6, 7, 8 are so proportioned that the potential at the anode of valve 5 is equal to that at point 9 when black level is applied to the control grid of valve 5 and will therefore be the same at the cathode of display tube 11 irrespective of the position of the contrast control 10. The signal at the anode of valve 5 also is supplied to a circuit for extracting the noise pulses comprising a series circuit formed by capacitor 16 and inductor 17 tuned to a centre frequency of 3 Mc/s., which is shunted by a diode 19 having a threshold bias determined by potentiometer 21, 22 so that the diode conducts in the presence of noise pulses with an amplitude exceeding that of the sync. pulses. These pulses are amplified by a valve 26 biased as a class B amplifier and supplied to block the sync. separator 14 and also supplied to the control grid of valve 15 in the A.G.C. circuit. Noise pulses below this level are selected by the tuned circuit 16, 17 and supplied to the valve 26 acting as an anode bend detector, the resulting pulses operating on the sync. separator and A.G.C. circuit as before. Equivalent transistor circuitry is described.

Abstract: 1,232,672. Metal detectors. RANK ORGANISATION Ltd. July 9, 1969, [July 10, 1968], No.32917/68. Heading G1N. A metal detector includes a self-checking facility. The detector comprises an A. C. energized primary coil L2 1. m. coupled to seriesopposed secondary coils L1, L3 from which an output voltage, indicating presence of metal perturbing the field of the coils, actuates an alarm relay RL1. To check the functioning of the detector, a resistor RV1 is connected across coil L1 by pulses through gate G from an oscillator Uo and monostable circuit Ms. The pulse length is insufficient to actuate the alarm relay but each pulse is counted by a circuit Pc. The test pulses produce from the coils a bias voltage at O which acts through Tr1 Tr2 to hold the fault relay RL2 inoperative. In the event that application of test pulses does not produce a bias voltage, Tr1 and Tr2 act to operate the fault relay, indicating a fault in the detector. There may be only one secondary coil.
