Title: Mounting arrangements
IPC: H05K7/14
Filed: 1976-05-27
Abstract: 1508832 Cabinets SMITHS INDUSTRIES Ltd 27 May 1976 [27 Feb 1975] 8198/75 Heading A4B [Also in Division H1] A mounting for electrical apparatus e.g. for electronic equipment in aircraft comprises, (Fig. 1), a metal cabinet 1 wherein individual rectangular units 2 are mounted in superimposed racks defined by horizontal plates 3; the units being front accessible by unlocking and raising a hinged lid 4 of each rack. The units are received in guideways formed by aligned channels 5 machined in opposed faces of plates 3 into which the units are slidable, and locked in by turn screws 6 clamping them against the sides of the channels for good earthing and heat conductivity to plates 3. Electrical connections of the units are made through mating plug and socket connectors (not shown) at the rear thereof and on the plate 3. Double width units 2A may be used, also resiliently intercoupled 2 way and 4 way units 2B, 2C with individual guide channels and circuit connectors. Air or other cooling fluid may be impelled between and through the units via apertures of plates 3, and the separate clamping of the units provide good earthing and electromagnetic screening. Structurally, Fig. 2, each unit 2 has a rectangular e.g. aluminium alloy metal frame 11 divided by crosspieces 12 into four bays each containing a ceramic substrate 13 of a circuit module 14, whose components are formed as discrete and integrated elements with printed circuit connections; inter-connections between adjacent modules being by surface mounted conductors overbridging the crosspieces, and the connectors 17 being connected to the circuits over conductor sheaves 18. The substrate clamped in the bays may be multi-layer, and may alternatively be of epoxy laminate board, while the frames may be closed with covers on one or both sides. The locking turnscrews 6 operate wedge locks lying in channels 20 at the top and bottom of each frame, which comprise metal bars 21 each with three spaced blocks 22 therelong on one side and a wedge cam 23 on the other engaging a wedge cam 24 of an adjoining bar 25 in the channel, longitudinally movable by turnscrew 6 rearwardly of the unit. Cam 24 engages cam 23 to urge bar 21 sideways and force blocks 22 through slots 26 of a sidewall 27 of channel 20 to abut one side of guide channel 5 and press the other side wall of channel 20 against the other side of guide channel 5. Thus the frame 11 is rigidly held to plate 3 with good thermal conductivity. The faces of the engaged side of the guide wall and of blocks 22 may have resilient thermally conductive gaskets thereon which are compressible on locking. Screws 6 are replaceable by quick release fasteners rotatable through 180 degrees. Multiple units are intercoupled over resilient metal strips 31 at front and rear bent into a U- shaped member 32 for insertion between the frames of adjacent units, with extending flanges 33 clamped thereto beneath fillets 34; the U- shaped member being compressible to accommodate mechanical tolerances between the linked units.

Title: Discharge-lamp manufacture
IPC: H01J9/395
Filed: 1974-02-22
Abstract: 1416287 Discharge lamps PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 22 Feb 1974 [16 March 1973] 8232/74 Heading H1D In a method of manufacturing a mercury vapour discharge lamp from an envelope provided with an exhaust tube 1, Fig. 1, a thin coating of amalgam is present on the inner wall of tube 1 from which, after exhausting the lamp, mercury is released by heating the amalgam, and the tube 1 is subsequently sealed between the envelope and the area where amalgam was present. A tube 2, which is inserted in tube 1, holds a small quantity of amalgam 3, e.g. an amalgam comprising 3 parts Hg to 1 part of In by weight, which is pushed out on to the side of tube 1 (Fig. 2, not shown) by a plunger 4. Tube 1 is then rotated to spread the amalgam over the inside surface (see Fig. 5), preferably with the help of an air stram. The exhaust tube 1 is connected to the stem 8 of a discharge lamp with an envelope 10. During assembly, the temperature of the amalgam 3 is kept low, by artificial cooling if necessary, so that no Hg is given off. Tube 1 is connected via hose 17 to low pressure, whereby gases can be removed from and introduced into envelope 10. When this process is complete, the amalgam layer 3 is heated as by a gas flame, an electric heater, or a concentrated light beam, to drive off Hg vapour into envelope 10; and the exhaust tube 1 is sealed and parted between the envelope and the region where amalgam was originally deposited. Alternatively, after exhausting and filling the envelope, the tube 1 may be sealed off beyond the amalgam layer 3. The amalgam is then heated subsequently, with final sealing of the tube.

Title: Process for the recovery of non-ferrous metals
IPC: C22B47/00
Filed: 1975-03-03
Abstract: 1500216 Recovering non-ferrous metals INCO Ltd 3 March 1975 [2 Aug 1974] 8696/75 Heading C7D In the recovery of one or more of Ni, Co, Cu and Mo from a manganiferous oxide material also containing Fe, particularly deep sea nodules, in which they are present as oxides, the material is reduced, smelted to produce a melt containing the desired metal(s) and a slag containing most of the Mn, after which the slag is removed, the melt is blown with gas containing free O 2  to further reduce the Mn content and the melt is sulphided to form a matte. The matte is blown with gas containing free O 2  to lower the Fe content, and further blown to remove the remaining Fe, after which the melt is granulated for subsequent recovery of the desired metals by conventional methods, e.g. by leaching or carbonyl processes. The reduction step is carried out at 750-1100‹C and reduces the desired metal compound(s) to the metal(s) and MnO 2  to MnO; this step may be carried out in a shaft furnace, rotary kiln or rotary hearth, and liquid, solid (e.g. coke) or gaseous reductants may be used. The sulphiding is effected by adding S, pyrite or pyrrhotite to the melt. Mn may be recovered from the slag by treating with coal, coke, Fe-Si or Si-Mn at a temperature above 1350‹C using limestone or dolomite as a flux.
