Title: Improvements in and relating to the manufacture of iron
IPC: C21B5/04
Filed: 1936-02-12
Abstract: In the production of pig iron in a blast furnace, especially from ores of low alumina content, the ores and fluxing media are mixed in such proportions as to form slags of relatively low melting points and in which the ratio of lime to silica is decreased progressively below the usual limits of 1,65 to 1,25 as the alumina content of the slag formed decreases downwardly from 15 per cent.  For example with a slag containing 15 per cent of alumina the ratio of lime to silica is from 1,15 to 0,90 and for as lag containing 10 per cent of alumina the ratio is 1,10 to 0,875.  The molten iron tapped from the furnace is desulphurized either by the addition of alkali or by allowing the liquid iron to stand in a heated receptacle under oxidizing conditions to enable manganese sulphide to be formed, sufficient manganese ores being added to the burden of the furnace, if required, to produce a pig iron having at least 0,7 per cent of manganese.  In the latter case, the iron is maintained in the hot metal mixer long enough for the manganese sulphide producer to be oxidized and the sulphur eliminated in the form of sulphur dioxide.  Specification 460,138 is referred to.

Title: Improvements in and relating to vapour or steam generators or boilers
IPC: F22B1/30
Filed: 1923-02-15
Abstract: 193,405. British Thomson - Houston Co., Ltd., (Assignees of Merrill, W. L., and Winne, H. A.). Feb. 15, 1922, [Convention date]. Generating by electricity.-A boiler of the kind in which steam is generated by the passage of an electric current between electrodes 19, Fig. 1, immersed in the water has an electrode chamber to which water is supplied continuously from a feed-chamber by a pump 28, and from which water overflows into the feed-chamber through small passages or pipes 25, the water level in the electrode chamber being maintained at such a height as to give the desired steam output or to utilize the desired amount of electrical energy. The water level may be maintained by regulating a valve 32 in the pump outlet pipe 30. The valve may be operated automatically by a motor 35 controlled by means responsible to the power supplied to the boiler. A blow-off valve 34 in the discharge pipe 33 may be similarly operated. The electrode chamber and the feed chamber are separated by a partition 18, which is perforated to receive the pipes 25 and pipes 24 projecting upwards to the highest water level permissible in the electrode chambers. The electrodes may consist of curved or angled plates, and partitions may be placed between the electrodes. The electrode chamber may consist of an open top vessel with perforated sides. Several electrode chambers may be arranged above a single feed chamber. The shaft of the motor 35 has a worm meshing with a wheel on the stem of the valve 32. The motor is supplied with current from a transformer 41, Fig. 2, in the line 22 connected to the boiler electrodes. The connection between the transformer and the motor is taken through switches 39, 40. When the switch 39 is closed, the motor is operated in a direction to close the valve, and when the switch 40 is closed the motor is operated in a direction to open the valve. The switches are operated by solenoids 45, 51, the currents through which are controlled by a switch 56 operated by a solenoid 57. The current flowing through the solenoid 57 is taken from a transformer 61 in the line 22, the switch 56 being therefore operated in accordance with the rise and fall of the power supplied to the boiler. The blow-off valve 34 is similarly operated by a motor 70 under the control of switches 73, 74 and a solenoid 112 energized by current from the transformer 61. Automatic and manually adjustable resistances 116, 115 control the strength of the current passing to the solenoid.

Title: Semiconductor crystalline device manufacture
IPC: H01S5/32
Filed: 1964-02-05
Abstract: 995,121. Lasers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 5, 1964 [Feb. 20, 1963], No. 4815/64. Heading H3B. [Also in Division H1] A method of making a plurality of lasers includes the steps of forming a bar of crystalline semi - conductor material having two parallel cleaved faces and dividing the bar into a plurality of pieces along directions transverse to the cleaved faces. The method is used to produce injection lasers, the process being illustrated in Fig. 4c. A crystal of N-type gallium arsenide doped with selenium is grown, for example by pulling from a melt in the 100 or 111 direction which favours crystalline perfection, and is then cut into wafers. Zinc is diffused into one surface of the wafer to produce a junction and the wafer is then cleaved into bars, the cleaved faces being spaced the desired Fabry-Perot interference distance apart. The bar is then subdivided by sawing, etching or cleaving. A laser formed by this method is shown in Fig. 7, the saw-cuts 41, 42 restricting the active area of the device while leaving the lower part 2 as a heat dissipating surface. Leads 9 and 11 are joined to the faces 8 and 9 of the device and the cleaved faces may be silvered to increase their reflectivity. The edge portions 44 of the device may be removed or may be used for signal input purposes. The diffusion of zinc into the wafer can also be performed after cleaving the wafer into bars, and specially shaped junctions can be formed by masking the surface of the wafer or bar during the diffusion. Alternatively the junction can be formed during the growth of the crystal. A plurality of interacting devices can be formed in a single element by extending the bottom of slots 41 and 42 (Fig. 7) parallel to the major faces of the wafer to undercut the edges of the slots which are then removed by cleaving to produce parallel faces. The whole element is also divided from the bar by cleaving.

Title: Improvements in and relating to an apparatus for perforating a layer in a master
IPC: B41C1/14
Filed: 1965-02-04
Abstract: 1,097,446. Local copying by scanning. ZEUTHEN & AAGAARD A.S. Feb. 4, 1965 [Feb. 5, 1964], No. 4964/65. Heading H4F. In an apparatus in which an original is scanned photo-electrically and a copy sheet is perforated by an electrode activated by signals from the photo-electric scanner, the photo-electric and electrode mechanisms are stationary whilst the original and copy sheet are carried side-by-side on a common drum which is subjected to both rotational and axial movements so as to cause helical scanning. The drum is supported by a main stationary shaft and rotated by a further shaft which engages rubber or plastic rings surrounding the periphery of the drum at each end. Within the drum and attached to it, Fig. 2 (not shown), are three intermediate shafts carrying bearings which may engage the main shaft. An adjustable mechanism accessible at one end of the drum permits the intermediate shafts, and hence also the bearings, to be displaced slightly away from parallel with the main shaft. By this means an axial force is imparted to the drum so causing it to progress along the main shaft as it rotates. A centrifugal mechanism, Figs. 3 and 4 (not shown), within the drum is arranged so that the rollers are brought into engagement with the main shaft only when the drum is brought to its correct rotational speed. The drum together with the main shaft may be removed from the apparatus for loading with the original and copy sheet, an interlock mechanism on a bearing for the shaft being provided, Figs. 5 and 6 (not shown), so that (1) the drum cannot be removed once the apparatus has been started into operation, and (2) the apparatus cannot be started without the drum in position. The start mechanism is also interlocked with an arrangement to connect the high voltage supply to the perforation electrode, Fig. 3 (not shown). By these means it is arranged that the electrode cannot be activated when the drum is removed and it is exposed to possible contact by an operator. At the end of its axial movement the drum engages a mechanism to stop the apparatus. The electric circuit (not described in detail) between the photo-electric scanner and the perforation electrode includes means for adjusting the signal level at which the electrode is activated. Suction apparatus is provided for removing waste products from the region around the electrode. The construction of the electrode and a holder is described with reference to Figs. 7 and 8 (not shown).
