Abstract: 1353937 Liquid/liquid extraction of highly viscous polymer solutions BRIDGESTONE TIRE KK and MITSUBISHI JUKOGYO KK 6 July 1971 [6 July 1970] 31650/71 Heading B1F A method of removing impurity from a highly viscous polymer solution comprises cbntinuously charging the solution via 5, and charging low viscosity immiscible solution via 7 and 7', into cylinder 1, and rotating shafts 3, 3' in opposite directions so that the highly viscous solution substantially avoids contact with the inside of cylinder 1 due to being retained by members 4, 4'. The treated highly viscous solution passes through the central opening in baffle 11, and is urged by roller 12 to outlet 6 for continuous discharge. Examples of solutions and impurities are given.

IPC: B21K3/04
Filed: 1954-11-02
Abstract: 797,667. Making turbine blades; destructible cores. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Nov. 2, 1955 [Nov. 2, 1954], No. 31656/54. Classes 83 (2) and 83 (4). A hollow body, particularly a hollow metal turbine blade, is made from a hollow deformable workpiece having a hollow or hollows filled with a core material of an alloy of iron and aluminium, the workpiece being deformed to the required shape and the core material being then removed by a reagent which does not substantially affect the workpiece. The alloy may also contain other materials. A turbine blade is made from a nickel alloy workpiece with one or more blind hollows each filled with a core of aluminium-iron alloy having from 30 to 70 per cent aluminium and from 70 to 30 per cent iron. The alloy may be in powder form and packed into the workpiece, it may be cast into rods and inserted in the workpiece or it may be poured in molten form into the workpiece. Each hollow is closed by a screwed plug and the workpiece is then forged to blade form at 1100‹ C. Finally each plug is removed and the core is dissolved with 25 per cent solution of hydrochloric acid at 70 ‹ C. Each blind hollow is then opened out at its closed end to form a through passage. Nitric acid or a mixture of nitric and sulphuric acid may be used to dissolve the core and will form a passive oxide layer in the hollow of the blade.

Title: Output stage for direct voltage amplifiers
IPC: H03F3/36
Filed: 1965-07-27
Abstract: 1,058,919. Direct-coupled amplifiers. TELEFONAKTIEBOLAGET L. M. ERICSSON. July 27, 1965 [July 27, 1964], No. 32111/65. Headings H3T and H3W. An output stage for a directly coupled amplifier for converting a balanced signal to a singleended signal comprises an inverting stage 1 (Fig. 1) joined to one input terminal 1 and an impedance-transforming stage 2 connected to the other terminal 1. With no potential difference between terminals 1 and 2, the anode potential of valve 1 is the same as the grid potential of valve 2. If the voltages at terminals 1 and 2 change equally and in the same direction relative to - A, the voltage at 2 after passing through valve 1 is equal and opposite to the voltage change at terminal 1 and valve 2 produces no output at 3. Differential changes at terminals 1 and 2, however, give an output at 3, the voltages adding at the grid of valve 2. A transistor circuit operating in the same way is also described (Fig. 2, not shown).

Title: Method and apparatus for reversing a workpiece for an automatic press line
IPC: B21D43/10
Filed: 1966-07-18
Abstract: 1,108,639. Endless conveyers. DANLY MACHINE SPECIALTIES Inc. 18 July, 1966 [2 Aug., 1965], No. 32193/66. Heading B8A. [Also in Division B3] Means for transferring and inverting work W between presses A, B comprises a conveyer 61 having spaced work-carriers 110, a wheel 120 for picking-up work on the conveyer, inverting the work and replacing it on the conveyer, and intermittent drive means for the conveyer and inverting wheel synchronized so that each operates during dwell period of the other. As applied to pressing instrument panels in presses A, B, C, each press has an arm 50 for transferring work from a conveyer on the delivery side of the press into the press and a further arm for transferring the pressed work from the press to another conveyer on the discharge side of the press, the conveyers being on supports 65, 75. Mounted on the conveyerframes are cruciform wheels 120 into the bifurcated arms of which the conveyers deliver the work. During a pause in the conveyer-feed, the wheels 120 are indexed through 90 degrees and remain in this position while the conveyers advance a distance d. The wheels 120 then progress a further 90 degrees to replace the work which has been inverted, on the conveyers. In this embodiment, the work is replaced in the same carriers 110, which are constructed, Figs. 5 and 6 (not shown), to accommodate the work in both upright and inverted positions. Drive for the conveyer or conveyers, wheels 120 and transfer arms 50 is taken from the associated press, through gearing, Fig. 4, including cams 96, 97 for driving the conveyer and cams 165, 156 for the wheels 120. The cams drive followers 99, 159 on shafts 100, 160 and are so arranged that the conveyer and wheels 120 have advances and dwells of equal duration, but those of the wheels 120 are at twice the frequency of the conveyer movements. An overload clutch, Fig. 3 (not shown), including spring-pressed pins (144), protects the wheels 120. In a modification, Fig. 12, the length of the arms 121<SP>1</SP> is such that when the piece is re-positioned on the conveyer after inversion it is engaged in a carrier one, three or five places ahead of the carrier from which it was removed. This effect can also be achieved by varying the indexing step " d " of the conveyer. Alternate carriers 210a, 210b are formed to accommodate the work in an upright or an inverted position, but not in both.

Title: Improvements in the production of concentrated nitrous gases and nitric acid

Filed: 1919-12-24
Abstract: 137,071. Norsk Hydro - Elektrisk Kvµlstofaktieselskab. Oct. 21, 1916, [Convention date]. Nitrogen oxides. - Dilutegases containing nitrogen oxides are treated with a solid absorbent consisting of a mixture of a base such as an alkali or alkaline earth hydrate with one or more metal oxides, which form easily decomposable compounds with alkalies and alkaline earths, such as iron, zinc, and aluminium oxides, the saturated absorbent being then heated to expel the nitrogen oxides in a concentrated condition. The absorption may be effected under pressure and at a raised temperature, for instance 400-500‹ C., and the decomposition may be assisted by steam or vacuum. In the example described, two retorts (or batteries of retorts) C, H are arranged to be used as absorbers and decomposers alternately. Hot gas containing nitrogen oxides is supplied by a valve B from a main A to the jacket of the retort C, which contains saturated absorbent to be decomposed, and a portion of the hot gas is admitted to the retort C by a valve D or by perforations in the retort wall, valves b, g, i being closed. Concentrated nitrogen oxides escape from the retort C by valve E and pipe F. The main part of the gases from the jacket of the retort C pass by valves G to the jacket of the retort H and thence through a valve D<1> into the retort H, where the nitrogen oxides are absorbed and the waste gases escape by valves J and pipe L. When the decomposition in C and the absorption in H are complete, the valves B, G, J are closed and the corresponding valves b, g, i are opened so that H becomes the decomposer and C the absorber.
