Title: Continuous production of steel
IPC: C21C5/52
Filed: 1975-04-03
Abstract: 1467948 Tapping furnaces; metallurgical converters FRIED KRUPP HUTTENWERKE AG 3 April 1975 [13 April 1974] 13737/75 Heading F4B [Also in Division C7] Steelmaking apparatus comprises (a) a shaft furnace 1 where scrap, sponge &c. is melted down to form a melt in tank 4, which may also receive pig iron at 9; (b) an electromagnetic conveyer 14 feeding the melt from tank 4, in counterflow to slag 18, to (c) a refining chamber 3, the waste gases from which pass over the conveyer 14 and into furnace 1 to heat the charge. Oxygen is blown through tuyeres 6, lances 5, 8 and blowers 7, the lances and blowers also feeding C, Si, Fe-Si, and/or Fe-P, if desired. In a modification (Figs. 3, 4, not shown), the melt is fed to the conveyer by a channel (16), some of which is then returned to the tank 4 by a further electromagnetic conveyer (17) positioned midway along conveyer 14.

Title: Improvements in or relating to braking devices
IPC: B66D5/00
Filed: 1923-05-24
Abstract: 215,587. Wade, H., (Alliance Machine Co.). May 24, 1923. - Blocks acting on drums; actuated by weights; electric and magnetic; compensating for wear.- A brake comprises a pair of shoe-carrying mem bers encircling a drum and having their ends connected to a pair of substantially parallel arms which may be attached to the plunger of a solenoid serving as a weight to apply the shoes to the drum when the solenoid is de-energized. The brake blocks 24, 25 are each secured between a pair of arms 22, 23, respectively pivoted at their ends by pins 18, 20 and 19. 21 to triangular plates 14 mounted on fixed pivots 4, 5 upon which parallel arms or levers 2, 3 are also adapted to turn. The plates 14 are connected to the levers 2, 3 so as to turn therewith by pins 13 which can be passed through any one of a series of holes 11, 12, 13 and 15, 16, 17 in the plates and levers. The levers 2, 3 are connected at 8, 10 to the armature 7 of a solenoid 6. The levers 2, 3 are initially adjusted in relation to each other by means of the pin 9 screwing into the armature 7, so that the blocks 24, 25 are concentrically disposed in relation to the drum. Assuming the solenoid to be energized, the parts are in the position shown with the blocks 24, 25 displaced from the drum. When the solenoid is de-energized, the weight of the armature 7 turns the levers 2, 3 and plates 14 about the pivots 4, 5 thereby moving the ends 18 - - 21 of the arms 22, 23 equal amounts to apply the blocks to the drum. To compensate for the wear of the blocks and thus prevent excessive downward movement of the armature, the pins 13 are withdrawn, the plates 14 are turned about the pivots 4, 5 relatively to the levers 2, 3 and the pins inserted in the next pair of holes in the. plates and levers. In a modification, separate plates 14 are dispensed with, and the members 22, 23 are instead pivoted to arms formed integrally with the levers 2, 3. In this case both of the levers 2, 3 are connected by screwed pins such as 9 to the armature 7 and adjustment for wear is made by inwardly screwing these pins. Specifications 1667/89, [Class 108, Road vehicles], and 3368/15 are referred to.

Title: Process for resolution of glutamic acid
Inventor: OGAWA TETSUO
Filed: 1957-05-07
Abstract: The invention comprises a process for obtaining L-glutamic acid and D-glutamic acid in succession by resolution of racemic glutamic acid in a solution containing racemic glutamic acid, water, and mineral acid or alkali, which comprises making and maintaining the solution supersaturated with respect to anhydrous glutamic acid at above 20 DEG C., inoculating the supersaturated solution with crystal seeds of one of the optically active forms of glutamic acid, maintaining the supersaturated state of the solution as the inoculated seeds grow under agitation, removing the multiplied crystals from the solution, adding racemic glutamic acid to the mother liquid to restore the supersaturated state at above 20 DEG C., repeating the inoculation with the other optically active isomer of glutamic acid, separating the multiplied crystals, and repeating the above steps successively in cycles. The supersaturated state may be produced and maintained by addition of racemic glutamic acid monohydrate as a solid phase, or by cooling, evaporation, or partial neutralisation, or by combinations of these methods.  When hydrochloric acid or ammonia is used as the third component in the supersaturated solution, seeding is effected with optically active glutamic acid hydrochloride or monoammonium glutamate respectively. Specification 773,661 is referred to.

Abstract: 1,049,494. Hay wafering apparatus. MASSEY-FERGUSON Inc. April 8, 1964 [April 24, 1963], No. 14591/64. Heading A2B. An apparatus for making compressed hay wafers comprises two pairs of opposed die walls defining a die cell having an entrance end communicating with hay compression means adapted to compress hay into and therethrough to form wafers and means respectively mounting said pairs of die walls for selective movement relative to each other. Fig. 1 (not shown) shows a section through a suitable apparatus, and Fig. 3 is an exploded perspective view of a portion of the die structure. Thus, hay is fed by means of feed screw 32 to an annular assembly of radial dies defined by end walls 40 and 42 and side walls 54 and 56, the hay being forced into the dies by compression rollers 38 carried by members 36 attached to shaft 14, the finished wafers being broken off by deflector 64.

Title: Improvements in or relating to the production of zirconia
IPC: C01G25/02
Filed: 1932-05-23
Abstract: A process for the production of iron-free zirconia comprises bringing impure zirconia or zirconium-containing material into solution, followed by the precipitation and removal of iron by addition of alkali ferrocyanide or ferricyanide.  Prior to treatment with ferrocyanide, the solution is, if necessary, treated with an oxidizing agent such as nitric acid; with ferricyanide a preliminary reducing treatment such as with sulphur dioxide may be advisable. These converting agents are subsequently boiled off.  Precipitation is preferably effected with stirring in the presence of diatomaceous earth.  Zirconium silicate ores are converted by fusion with, e.g. sodium hydroxide or carbonate, the product being dissolved in acid, preferably in sulphuric acid, and after recovery of the alkali by hydrolysis. Zirconium oxide ores are treated, e.g. with 20 per cent oleum at 140--150 DEG  C., and the mass evaporated to dryness, extracted with hot water, and filtered.  Zirconia is obtained from the purified solution by addition of alkali, washing and calcination, or by evaporation and calcination.  Alkali ferrocyanide may be regenerated from the precipitate by treatment with alkali.

Title: Electric Incandescent Lamps Filled with Argon.
IPC: H01K1/50
Filed: 1916-10-14
Abstract: 102,141. Allgemeine Elektricitats- Ges. Nov. 11, 1915, [Convention date]. Residual gases.-To allow of filling bulbs with argon nearly or quite free from nitrogen, without danger of arcing in use, traces of electro-negative gases or vapours, or compounds emitting them, are introduced. Red phosphorus, for example, may be placed on the bulb, leading-in wires, supports, or other parts. Phosphorus may also be vaporized in the sealing-off tube before fusion, as is done in vacuum lamps. Other less suitable substances are halogens, pure oxygen, sulphur, selenium, telurium and gas-evolving compounds such as barium chlorate or thallium thallo-chloride. The pressure of electro-negative gases should not exceed 0.01 mm. of mercury. Fifty mgr. of either of the solids mentioned may be used in a lamp of 200-1,000 candle-power. Water vapour must be excluded. As argon has a lower heat-conductivity than nitrogen, low-power lamps can thus be produced which consume 0.1 watt per candle less than those containing a known nitrogen-argon mixture.
