Title: Improvements relating to the dry reduction of ores
IPC: C22B5/00
Filed: 1952-05-26
Abstract: In a method of reducing ore to metal without melting in a vertically extended, externally heated reduction chamber, there is provided centrally of the chamber an axially extending zone with a lower resistance to gas flow than that of the remainder of the chamber by charging the zone with material that is coarser than that in the remainder of the chamber, so that the hot gases developed during reduction are caused to flow substantially radially inwardly so ensure a more even heating of the charge. This inner zone may be established by inserting a tube into the chamber which is filled with coarse material while the space around the tube is filled with less coarse ore and reducing agent. The tube may be gradually removed as charging proceeds or it may be withdrawn after charging is completed. The tube may be left in the furnace and in this case it may be made of a material which is completely or partially consumed during reduction, e.g. paper or cardboard.
Patent GB-378486-A (GB)
Title: Improvements in or relating to liquid heating systems
IPC: G01K17/16
Filed: 1931-05-05
Abstract: 378,486. Heating by circulation of fluids. BARON, H., 231, Strand, London.- (Soc. pour le Perfectionnement de la Chaufferie ; 4, Rue de Mondovi, Paris.) May 5, 1931, No. 13310. [Class 64 (ii).] A hot water or other liquid circulating heat distribution system is provided with means for metering the heat output while keeping the resistance to flow in the liquid circuit constant. In one form, Fig. 1, a hot water distribution pipe 1 and cold water return pipe 2 have in shunt a branch circuit comprising radiators 3, 4, with supply and return pipes 5, .6. The hot water passes through a coil 8 in a heatexchanger 7 through which the cold water can be diverted by. a mixing cock 9, thus enabling the temperature of the water supply to the radiators 3, 4 to be regulated. The supply and return pipes of each radiator are connected by a tube 10 lagged or otherwise heat-insulated and having no appreciable resistance to the water flow, so that the circulation through the radiator can be adjusted by a cock 11 without varying the resistance of the circuit. Cocks or needle valves 12 in each radiator circuit are adjusted permanently when starting the installation. The heat metering system consists of an electric meter 13 connected to the terminals of a thermopile 14 which are at the temperature of the water entering and leaving the circuit. The meter 13 is shunted to a degree corresponding to the water pressure in the installation by placing resistances in shunt therewith by means of contacts closed or opened by variations in the discharge pressure of the water, e.g. by providing resistances R which are connected in the circuit by a mercury manometer 15 connected to a conduit 16 the pressure in which is always that of the pump circulating the water. In another metering arrangement, Fig. 2, the meter 13 is connected to the terminals of the thermopile 14 the hot junctions of which are each connected to a contact in the branch of the mercury manometer 15 which is connected to the circulation system. In a further arrangement, Fig. 3, the meter 13 is connected on a bridge 26 across the terminals 19, 20 of two opposed circuits each containing a current source 21, 23 and a resistance 22, 24 which is variable with temperature and which may be combined with a fixed resistance. To cause the variations in pressure in the liquid circulation system to govern the heat measurement, a contact manometer is provided similar to that of Fig. 1, and controlling the potential difference between terminals 19, 20. For example, if sources 21, 23 are secondary cells or transformers the contacts of the manometer act to put into the circuit a number of cells or of tappings dependent on the water pressure.

Title: Optical control of crystal growth
IPC: C30B29/66
Filed: 1973-03-20
Abstract: 1374065 Elongated crystalline bodies TYCO LABORATORIES Inc 20. March 1973 [10 July 1972] 13330/73 Heading BIS An elongated crystalline body, e.g. a tube is made by pulling the body from a pool of a melt which has a vertical meniscus and is: replenished via a capillary member from a reservoir containing the melt, optionally measuring the height of the meniscus and monitoring this height by adjusting either the speed of pulling or the rate of heating to maintain the height of the meniscus with chosen limits. The body is preferably grown from a seed crystal. The body is preferably made either by the edge-defined film fed growth process, (E.F.G. method, see Fig. 1, not shown) or from a column of melt fed from a reservoir (S.F.T. method, see Fig. 2, not shown). The body in addition to a tube may be a rod, filament or ribbon. The material may be alumina, barium titanate, beryllium oxide, titanium oxide, chromium oxide, lithium niobate; lithium fluoride, calcium fluoride, or sodium chloride. Fig. 4 shows a preferred method of carrying out the invention which permits monitoring and measurement of meniscus height by means of a microscope system. A molybdenum crucible 2, filled with high purity alumina is mounted on short tungsten rods 80 within a carbon heat susceptor 82 supported by a tungsten rod 84. The susceptor is enclosed in a radiation shield 85. Heating coil 86 of the furnace surrounds susceptor 82, the crucible contains three die assemblies of which only 4c is shown, plus a hollow filler tube 59, all of which are supported by plate 16. The bottom end of tube 59 terminates near the bottom of the crucible whilst its upper end terminates above plate 16. A delivery tube 61, is sealed into the furnace and has its bottom end terminated adjacent the upper end of filler tube 59. The filler tube and delivery tube permit replenishment of the melt without interrupting crystal growth. The tubular body is grown from a melt film (supported on the upper surface of each die assembly by the known E.F.G: method and associated with pulling rod 68 to which is attached seed holder 70 capable in this case of holding three seeds 72 each aligned with one of the three die assemblies 4a-c. Measurement of the meniscus is effected by quartz pipe 64 closed by endwall 66 directed in this' case to die assembly 4c and viewed by microscope 74. If desired two 'ore more crystalline bodies may be grown simultaneously and at the same ratefrom individual growth pools of melt which are replenished via capillary members from a reservoir supply of melt and wherein each pool has a vertical meniscus which extends between the interface thereof with one of the bodies and the edge of one of the capillary members, by monitoring the height of a single meniscus and adjusting the rate of heating of the growth pools of melt so as to maintain the height of the monitored meniscus at a value such that the body associated with the meniscus will grow to a cross-sectional size substantially half-way between maximum and minimum limits.

Abstract: 992,571. Heating packaged food. P. EISLER. April 14, 1961 [April 14, 1960], No. 13383/60. Heading A2D. [Also in Divisions A4 and B8] A package includes a low-voltage heating film and displacing means for mechanically displacing the contents of the package relative to the heating film. The main use is for cooking, heating or thawing food. The following are examples of the various embodiments described. The embodiment shown in Fig. 1 comprises a rigid dish 6 having a heating foil 11 and covered by a transparent sheet 8. When the contents, e.g. food, have been heated the cover 8 is removed and the heating foil is withdrawn through a slot 12 in a sheet of cardboard 9, thus stripping the food from the foil. The embodiment shown in Fig. 8 comprises a heated foil 25 folded so as to form partitioning members 22 which pass through slots 6 in rigid plate members 23, 26. The plate 26 has a tab 27 which can be pulled to withdraw the plate 26 together with the foil, while the fixed plate 23 strips the contents from the foil. The embodiment shown in Fig. 10 comprises a rigid container 28 having a narrow neck 29. The foil passes through the neck as shown and a current is passed through it by means of a spring contact clip indicated at 33. When the contents have been heated, the withdrawal of the foil causes it to be squeezed as it passes through the neck thus stripping the contents. A patch of ink on the container changes colour when the contents have reached the desired temperature. In the embodiment shown in Fig. 11, separately wrapped portions of food 91 are suspended in a box 94 by means of aluminium foils folded concertina fashion, the foils passing through slots in the wrappers. The foils also support heating films 93. The bottom of the box is insulated by means of corrugated or honeycombed asbestos paper. A cover may be lowered into the box to collapse the foils to allow the heating films to contact the packages during an initial heating period and then the cover may be raised and the box suspended by the cover during the remaining heating period. In the embodiment shown in Fig. 16 a wrapped loaf may have any number of slices cut off between the foils 112. The selected portion is then expanded and connected to a low voltage supply to make toast. In a further embodiment (Fig. 19) a vacuum pack containing ground coffee is expanded and heated to roast the coffee. It may be shaken by hand or automatically during this process. The airtight outcover of aluminium foil is then wholly or partially removed to expose internal filter discs and the pack is then used as an infusion bag.
