Abstract: The invention comprises cyclotetraphosphines of the general formula: <FORM:0965266/C1/1> wherein each R is the same or different alkyl, cycloalkyl, alkenyl or aryl radical.  The compounds in which R is alkyl, cycloalkyl, or aryl may be obtained (a) by heating at from 50 DEG C. to 100 DEG C. in an inert atmosphere one or more primary phosphine oxides of the formula R.P(O)H2 wherein R is an alkyl, cycloalkyl or aryl radical, (b) by reacting at from 25 DEG C. to 100 DEG C. in an inert organic solvent a phosphine of the formula RPH2 with a dihalophosphine of the formula RP(Halogen)2 wherein R is alkyl, cycloalkyl or aryl or (c) by reacting the above specified dihalophosphine RP(Halogen)2 at from -80 DEG C. to + 100 DEG C. with a reducing metal, e.g. sodium, potassium, lithium or magnesium.  The products in which R is an alkenyl group may be obtained by reacting phosphorus pentachloride with an a -olefin and then removing hydrochloric acid from the product by treatment with a base. Suitable inert organic solvents for method (b) above and which may also be present in the other defined reactions are benzene, toluene, xylene, naphtha, hexane, ether, dioxane, tetrahydrofuran, and the dimethyl ether of diethylene glycol. Several examples are given and the products are useful as additives for motor fuels (see Division C5). The primary phosphine oxides used as starting materials may be obtained by reacting a ketone with phosphine in the presence of a mineral acid, e.g. hydrochloric acid, sulphuric acid or phosphoric acid or by oxidising a primary phosphine in a polar solvent, e.g. alcohol, at a temperature not exceeding 0 DEG C., thus octyl phosphine may be converted to octylphosphine oxide by treating it with 30% aqueous hydrogen peroxide at 0 DEG C. in alcohol.ALSO:A motor fuel comprises gasoline, tetraethyl lead in an amount sufficient to impart anti-knock properties to the fuel and from about 5% to about 200% by weight of the amount theoretically required to convert all the tetraethyl lead to lead orthophosphate of one or more cyclotetraphosphines of the general formula <FORM:0965266/C4-C5/1> wherein each R is the same or different alkyl, cycloalkyl, alkenyl or aryl radical (see Division C2).  Specified cyclotetraphosphines used in the examples given are tetra 3-pentyl-, tetra n-octyl-, tetramethyl, tetraphenyl-, tetracyclohexyl-, tetrabutenyl-, diphenyl di-n-octyl-, diphenyl diisobutyl-, and diethyl dicyclohexyl cyclotetraphosphines.  The cyclic phosphines are stated to suppress pre-ignition to a significant extent.

Title: Radiation detector
IPC: G02B23/12
Filed: 1954-10-08
Abstract: 754,411. Radiation detectors. STANDARD TELEPHONES & CABLES, Ltd. Oct. 8, 1954 [Oct. 13, 1953], No. 29051/54. Class 40 (3). [Also in Group XL (a)] Apparatusfor detecting infra-red radiation comprises photo-conductive cadmium sulphide co-operating with electroluminescent material. The cadmium sulphide used is the particular crystal whose resistance decreases in response to visible radiation and increases in response to infra-red radiation. In Fig. 1 such a crystal 5 is in front of an exciter 1 comprising an electroluminescent layer 2 and transparent electrode 4 and both 5 and 1 are in series with an infra-red indicator 11 which is a duplicate of the exciter 1. In use, A.C. at 10 (e.g. 600 volts) is applied across the series circuit 5, 1, 11 (see Fig. 2) and then 5 in response to visible radiation decreases in resistance so that voltages across 1 and 11 increase and. the layers 2, 12 luminesce and the crystal 5 now receives visible radiation from layer 2 so that the apparatus is regenerative in operation and the original visible radiation used to trigger the crystal 5 into a low-resistance state is not required. When infra-red radiation impinges on the crystal 5 the latter's resistance suddenly rises and causes the exciter 1 and indicator 11 to extinguish and the non-glowing of indicator 11 immediately informs an observer that infra-red radiation is striking the crystal 5. The apparatus may be embodied in a helmet or hat, Fig. 4 (not shown), so that the wearer may observe the infra-red indicator 11. The electroluminescent material used may consist of a copper activated zinc oxide and zinc sulphide mixture.
