Abstract: ABSTRACT      An auxiliary air cooling unit cools and dehumidifies air entering an air-conditioned building.  The auxiliary unit operates in response to increased temperature and/or moisture content of the outside air to prevent air of undesirably high moisture content from entering the building.  As the auxiliary unit operates selectively during periods of increased cooling load, it avoids or reduces problems of over-cooling of the air in the building by the main air-conditioning unit and reduces the need for periods of inefficient reduced-power operation of the main unit.

Abstract: The present invention relates to a process for purifying metals, such as aluminum, by segregation, wherein, by controlled cooling in the upper part of a volume of liquid metal to be purified, which is contained in a crucible and disposed in a furnace, small crystals are caused to form, the crystals falling towards the bottom of the container under the force of gravity. The small crystals are compacted so as to cause the formation of a compact layer of large purified crystals. This process is distinguished from the known processes in that, to enhance the purification effect, the thermal flux is so adjusted as to completely and progressively re-melt the lower part of the mass of large crystals which are formed, with the re-melting action being propagated upwardly so as permanently to maintain a layer of large crystals which separates the re-melted liquid entirely disposed in the lower part from the remaining mother liquor. That process makes it possible to attain extremely high levels of purification, in relation to very high fractions of the initial mass of aluminum which is to be purified. The process can be applied to metals such as aluminum, lead, zinc, magnesium and silicon containing eutectic impurities in hypoeutectic amounts.

Abstract: \                 ABSTRACT OF DISCLOSURE  OPTICAL ALIGNMENT MEANS    A method of aligning an optical fibre with a light source, such as a solid state laser, comprises substantially aligning the axis of optical fibre with the light source and locating two lenses between the fibre and the source.  One of the lenses is fixed and the other is movable in a plane perpendicular to the axis of the fibre.  The lens is moved until the image of the light source is focussed on to the end of the fibre, the fibre also being axially movable.    The method can be termed an "optical lever", movement of the lens causing a smaller movement of the image.  The requirement for fixing the fibre or the lens extremely accurately is therefore reduced.

Abstract: FERRITE MODULATOR ASSEMBLY FOR BEACON TRACKING SYSTEM                 ABSTRACT       A modulator system (30) for converting a three-channel input microwave signal to a single-channel output microwave signal is formed of two (upper and lower) microwave sections which are joined together by a hybrid divider (94) at their inputs and by a hybrid combiner (96) at their outputs. Each of the microwave sections includes a pair of couplers (82 and 84, 88 and 90) which are joined by a Faraday rotator (86, 92).  First and second microwave input signals (48, 52) are applied to a first port of the input coupler (82, 88) in each of these sections.  A third microwave signal (50) is directed by the hybrid divider (94) to a second input port in the input couplers (82, 84) of each of the microwave sections.  Polarization of the third signal is vertical and is maintained through the two sections.          Polarization of the first and second signals is horizontal and is maintained through the two sections.  With activation of the rotator, a shift in polarization occurs resulting in appearance of the signals in both the horizontal and vertical components of an output coupler in each of the sections.  The vertical component of the output couplers in each of the sections is combined by the hybrid combiner to produce the single-channel microwave signal (54).  Synchronous detectors are utilized for subsequent extraction of the first and second input signals, the synchronous detectors and the Faraday rotators being driven by common sources of modulation signals wherein the rotator in one section is modulated at a rate different from the rotator in the second section.
