Title: Improvements in or relating to methods of coating vitreous materials with alkaline earth metal oxides
Inventor: EVANS RONALD ALBERT
IPC: C03C17/245
Filed: 1968-11-21
Abstract: 1,248,747. Oxides of magnesium, calcium, strontium and barium. GENERAL ELECTRIC CO. Ltd. 7 Nov., 1969 [21 Nov., 1968], No. 55246/68. Heading C1A. [Also in Division H1] A siliceous vitreous surface which is subject to attack by alkali metal vapour is treated by exposing said surface, in the absence of moisture, to the vapour of an organic compound of magnesium, calcium, strontium or barium, which compound is decomposable at a temperature below the softening point of said vitreous material to yield the free oxide of said metal, and heating the said surface while so exposed to a temperature at which such decomposition takes place and the liberated oxide is deposited upon the surface to form a continuous adherent protective coating. The metallic compound is preferably a compound in which the metal atom is linked directly to one or more oxygen atoms in the molecule and which vaporizes at not more than 300‹ C. such as a chelated diketone, preferably magnesium acetylacetonate. The organo-metallic compound may be in admixture with a carrier gas which may be a rare gas such as Ar, N 2  or a mixture thereof with 0 2 . The treatment may be used for the interior surfaces of discharge envelopes of alkali metal vapour discharge lamps (see Division H1)

[Also in Division B8] Apparatus for applying identification dots to the curled top rims of cone-shaped supports comprises a spigot along which the supports may slide a resilient marking tube projecting laterally from the spigot, and means for supplying marking liquid or paste to the tube, the end of the tube remote from the spigot being inclined at an angle to the axis of the tube. Fig. 1 illustrates apparatus wherein cone-shaped supports 3, e.g. yarn supports, are mounted on a form 2 attached to base 1; a spigot or rod 4 is slidable through the base 1, form 2 and supports 3 and marking cartridges, e.g. 5, 6 are removably secured to the top of the rod, each cartridge having a rubber tubular member 8 and, at a lower level, a resiliently mounted pivotable pin 9, and a plurality of cartridges being employed in any one apparatus. Upward movement of the spigot 4 and hence the cartridges through the pile of supports 3 causes no marking, the identification dots being applied only during downward movement. Each marking cartridge, Fig. 2, has an ink reservoir 10 connected to the tubular member 8 via conduit 11; the tubular member 8 is resilient and clamp means are provided for restricting the flow of marking liquid or paste except when released in response to pivoting of the pin 9 under the action of the supports passing it. The viscosity of the marking liquid or paste is adjusted to delivering the desired quantity in each cycle.

Title: Shaft position encoders
Inventor: BLATCHFORD WILLIAM CHARLES
IPC: H03M1/00
Filed: 1967-12-21
Abstract: 1,219,108. Light modulators. W. C. BLATCHFORD. 21 Dec., 1967, No. 58109/67. Heading H4F. [Also in Division G1] A beam of polarized light the angle of polarization of which is periodically modulated is applied to an analyser mounted for rotation with a shaft and the phase difference between the resultant output and the modulated beam is used to drive a coded signal representative of the angular position of the shaft. The modulation may be effected by Pockels cells or by rotating the polarizer. The light may pass through the analyser to a detector positioned behind it or as detailed below the analyser may comprise a polarizing filter or film 48 and a mirror 46 which reflects the light. As shown, light from a lamp 12, collimated by a lens 16 and polarized at 45 degrees azimuth by a filter 18 is applied to a quarter-wave plate 20 which produces a 90 degrees phase shift in the components. The output passes through two Pockets  cells 30, the driving frequencies of which are 90 degrees out of phase and are directioned at 0 to 45 degrees azimuth respectively. This has the effect of producing an elliptically polarized beam with the major axis of the ellipse rotating at a velocity proportional to the driving frequency. This beam passes through a beam splitter 38 and after reflection and modulation at the analyser 40 mounted on the shaft 42 is reflected by the beam splitter on to a detector 44. The signal derived from the detector comprises a direct current signal which is filtered out by a filter 46, a signal displaced in phase from the modulating signal as applied to the first Pockels cell and signals of a much smaller order. This phase difference is measured by a digital time interval counter which receives the output of the filter 46 and modulating signals from the first Pockels cell.
