Title: Improvements in or relating to methods of forming silica coatings on refractory substrates
Inventor: NASSIBIAN ARMENAG GARABED
IPC: H01G4/08
Filed: 1961-05-12
Abstract: A silica coating is formed on a refractory substrate by thermal evaporation in vacuo, and then the coated substrate is heat-treated at not less than 1000 DEG  C. to render the coating substantially non-porous and to improve the adhesion of the silica coating to the substrate.  The substrate is of silicon but may be metallic.  The silicon substrate is maintained at about 1000 DEG  C. during coating by being supported on a horizontal strip or sheet of tungsten functioning as a heated electrical resistor.  Silica is evaporated from a short rod held above the substrate and heated to 1800 DEG  C. by electron bombardment.  A suitable mask may be used and the exposed parts coated with silica of about 2 microns thickness.  After coating the silicon body is heat treated in dry nitrogen at 1200 DEG  C. for 30 minutes and then slowly cooled to room temperature. Alternatively, an atmosphere of dry oxygen may be used and the superficial oxidation of the previously masked areas removed by immersion in 40% hydrofluoric acid.  Specification 909,503 is referred to.

Title: Improvements relating to multiple-pin, two-part electric couplings
IPC: H01R13/621
Filed: 1949-07-04
Abstract: 670,113. Two-part couplings. BRITISH INSULATED CALLENDER'S CABLES, Ltd., DIXON, H. J., CHAPMAN, E. G., and GAUTERIN, A. G. July 3, 1950 [July 4, 1949; Dec. 1, 1949], Nos. 17588/49 and 30890/49. Class 38 (i). In a multiple-contact coupling, wherein each pair of engaging contacts 1, 2 is moulded in the inelastic insulating bases 3, 4, a substantial length of each pin thereof is left unsupported by the bases when in the fully-engaged position in order that the contact pairs may be easily engaged, notwithstanding misalignment due to shrinkage of the cooling moulded body. Preferably the pin contacts 1 project beyond the face of the base 3 a distance of twice the depth of the pin-receiving portion of the socket 2 and it may have at the base 3 a portion 1a of less diameter than the remaining projecting portion. Alternatively, the insulating base 4 surrounding the pin is recessed away therefrom (Fig. 2, not shown). To enable assembly of the coupling parts, a locating jig 30 fitting into the metal cover 15b of a coupling part and apertured at 32, receives the contacts and thereby positions them when the moulding material is run into the cover. To control the amount of misalignment, the pattern of the contacts on each of the coupling parts is displaced symmetrically by a small amount, Fig. 7, so that each engaging contact pair is slightly stressed. For this purpose the jig 30 may have dowel pins inserted through apertures 32 to receive and locate the sockets, thereby ensuring that, when assembled, both pins and sockets partake of the misalignment. Alternatively, Fig. 10, a key 37 having a helical thread is provided on one coupling part to engage in a keyway in the other part to stress the engaged contacts. The first Provisional Specification refers also to leaving the sockets, or both the pins and sockets, unsupported by insulating material.
