Title: Process for producing monocrystalline whiskers of magnesium aluminate spinel
IPC: C30B25/00
Filed: 1976-05-24
Abstract: 1511393 Spinel whiskers LENIGRAD TEKHNOLOGICHE INST IM LENSOVETA 24 May 1976 21385/76 Heading C1A Spinel whiskers are made by calcining magnesia and alumina at 1300-1800‹C in air in an enclosed space in the presence of a carbonaceous material, the whiskers growing on the alumina surface. The reaction is preferably performed in the presence of aluminium sulphide which is present in the ratio of sulphide : magnesia of 1:5-10. The carbonaceous material may be solid carbon, preferably graphite, or a gas such as CO or CO 2 . In one embodiment a column of stacked tablets of magnesia is inserted along the axis of a cylindrical alumina vessel and graphite is poured into the bottom of the vessel. Certain of the magnesia tablets may be replaced with tablets of aluminium sulphide or a single moulding of magnesia or mixture of magnesia and aluminium sulphide may be employed. In another embodiment tubular members of alumina and magnesia are arranged alternately in concentric circles and the arrangement is placed between two graphite plates. In a further embodiment a plate of alumina and a plate of magnesia are spaced by graphite plates. Any of these constructions are then placed in the furnace for calcination. Preferably the distance between the magnesia and alumina is less than 30 mm.

Abstract: 575,010. Window operating-apparatus. TRICO PRODUCTS CORPORATION. Dec. 21, 1943, No. 21404. Convention date, Jan. 2. [Class 20 (iii ] A window regulator of the kind comprising a pressure operated piston connected by a band &c. to the window and provided with locking means preventing lowering of the window by external force is provided with means for rendering the locking means inoperative when desired. The means shown consists of brake shoes 21 engaged with rods 22 through toggles 25 operated by movement of the piston member 12 when the window is pressed down by hand. Back supports 29 for the rods are connected by integral cross pieces 30. The rods have flats 33 so that when rotated into the position shown in Fig. 6, they are out of engagement with the brake shoes. The rods are rotated for this purpose by links 34, 35 and a control rod 36 having a handle 37, Figs. 3 and 4. Depressing the handle 37 also lowers the bar 5 on the window allowing enough space for insertion of the fingers above the glass for hand operation. Specification 565,137 is referred to.

Title: Device for winding wire into a coil to form eventually a  sliding clasp fastener element
IPC: B21D53/50
Filed: 1972-05-08
Abstract: 1396036 Coiling single plastics thread YOSHIDA KOGYO KK 8 May 1972 [7 May 1971] 21428/72 Heading B8G Wire 21 from the bobbin 16 is formed into a helix 33 suitable for further processing on a slide fastener. Mounted in sequence on a fixed hollow axle 22 are: (a) a bobbin driving rotor 13; (b) the bobbin 16; (c) a winding rotor 18; and (d) an ultra-sonic oscillation head 28 comprising an oscillating sonotrode 29 with a winding mandrel 32. The mandrel 32 may have an at least partly frusto-conical winding head 30. The rotor 13 drives the bobbin 16 to loosen the wire therefrom and the rotor 18 winds the wire 21 about the mandrel 32, the power drive to the rotors 13 and 18 being such that a constant tension is maintained in the wire 21. In the embodiment shown this is achieved by using a slipping belt drive 61 to turn the rotor 18, the drive 61 being set to tend to turn the rotor 18 faster than the bobbin 16 but failing to do so due to slippage. The wire 21 may be of plastics and may have any cross-section. The coil 33 is brought rapidly to a desired working temperature by means of the ultra-sonic oscillation energy. The mandrel 32 is exchangeable for another mandrel of different size. In an alternative embodiment of the invention (not shown), drive-shaft 8, wheels 60 and 62 and toothed band 61 are eliminated and winding rotor 18 is driven directly by bobbin 16 through a clutch. The clutch is associated with a brake adapted to engage the winding rotor 18 so as to control its speed in a manner keeping the tension in the wire at a low and constant level.

Title: Improvements in and relating to processes and apparatus for evaporating liquids in two stages
IPC: B01D1/26
Filed: 1946-07-18
Abstract: <PICT:0621967/III/1> In a two-stage evaporation process, the liquid is heated under pressure and partially evaporated, the vapour therefrom being used to preheat the entering liquid.  The liquid then passes to flash evaporator in which it cools to approximately the inlet temperature of the liquid.  In concentrating artificial silk spinning solution, the solution is pumped from tank 17 through preheater 2 to the steam-heated evaporator 3 and thence through separator 18 from which the vapours go to preheater 2 and the concentrated solution passes through adjustable throttle 20, to the flash evaporator 9 provided with a barometric leg 22 which feeds the concentrated solution to tank 21.  The vapours from the flash evaporator are condensed in spray condenser 23 to which is connected a steam-jet pump 27.  A byepass 19 on the outlet from separator 18 allows for recirculation to the first evaporator of part of the liquid leaving the separator.  In another embodiment, Fig. 1 (not shown), seawater is evaporated to provide distilled water by admixing the condensed vapours from both evaporators.  The rate of feed from the first evaporator to the flash evaporator is controlled by a float valve operated by the liquid level in the first evaporator.
