Abstract: A binary compound XY is formed by mixing two exothermic reacting elements X and Y together and heating to above the melting point of the element X having the higher melting point; X being of particle size, e.g. less than 44 m , such that it is all consumed.  One of the elements may be from Group IIb (Zn, Cd, Hg) or IIIB (Ga, In, T1) and the other from VB (P, As, Sb) or VIb (S, Se, Te).  Particles of Y may be 1/8 -inch, or the same size as X.  A metallic element, e.g. Cd, may be used with an oxide coating, or this may be removed by treating with concentrated aqueous ammonia, washing, and drying in air or vacuum at 100 DEG  C., or by reducing in H2 at 200 DEG  C.  The mixture of X and Y is placed in an ampoule which is evacuated or filled with an inert gas and sealed, then heated at 0.1 to 5 DEG  C. per min. to 5-100 DEG  C. above the melting point of X and cooled slowly or by air quenching.  The product may be ground and the heating cycle repeated.

Rabbits or calves are immunised with a homogenate of 12 - 14 day sheep embryos emulsified with an equal volume of Freund's adjuvant, repeatedly at weekly intervals, and blood is removed 6 days after each injection. Serum from the blood is purified from unwanted antibodies by absorption with homogenates of liver or kidney from non-pregnant sheep. The anti - embryo serum may be used for diagnosing pregnancy by mixing with whole blood, erythrocytes, serum or plasma from the animal being tested and examining the mixture by a method for detecting antigens, e.g. agglutination or agglutination - inhibition techniques, precipitation and immunofluorescence or radioimmunoassay tests.

The inner conical electrode 52 is connected via flange 55 to electrode 38 of the ion gun and may be maintained at - 700 volts potential and extends into the quadrupole as far as the focal point f of the ion beam in order to shield it from the defocusing effect of the fringing fields near the quadrupole entrance. The outer electrode 54 is connected to the housing 10 from which the primary electrodes are insulatingly supported and is maintained at the quadrupole ground potential to shield the quadrupole from the effect of the negative potential on inner electrode 52. The quadrupole may be followed, in the beam direction, by a fringing-field compensating structure comprising a first electrode 60 at quadrupole ground potential and a second electrode 62 at a negative D.C. potential which is proportional to the D.C. excitation voltage applied to the quadrupole. The ion beam is formed by electron bombardment of a sample gas and is extracted and focused by repeller electrode 34, e.g. at + 5¢ volts, electrode 36 with curved conductive mesh 40, e.g. at +5 volts, and electrode 38 at - 700 volts. Relative dimensions of the ion gun electrode and the distance of the ion focus f from the centre of curvature C is discussed. For applications other than use in the vacuum of space the mass filter is housed in an evacuated enclosure.
