Patent GB-915874-A (GB)
Title: Process and apparatus for the separation of reaction products from gas mixtures
IPC: C07C51/573
Filed: 1959-07-03
Abstract: <PICT:0915874/III/1> Reaction gases produced in a catalysis chamber enter deposition apparatus 21, where the reaction product from a previous production has been precipitated, fusing the product by indirect-heat-exchange without any deposit of fresh product.  The gases then pass to heat-exchanger 19 and then into a second deposition chamber which cools below the dew point, with consequent deposition of crude reaction product.  By valve arrangements the order of the deposition chambers can be changed. The melted product is subseuently subjected to purifying distillation.ALSO:Phthalic anhydride produced by the catalytic oxidation of naphthalene as a hot vapour is first heat-exchanged with crude condensed anhydride from a previous reaction; then passed through a heat-exchanger to bring the temperature nearer the dew point and is finally cooled to give a crude reaction product for melting. The melted product is purified by distillation.

Title: Process for separation of mixtures of particles differing in specific gravity, by means of suspensions of magnetizable particles in a cyclone
IPC: B03B5/34
Filed: 1950-09-20
Abstract: In a process for the separation of particles of differing specific gravity in a suspension of magnetizable particles in one or more cyclones, at least a part of the magnetizable particles are introduced into a cyclone in a magnetized condition.  The light and heavy products may be discharged on to screens and washed, the washings being passed through a magnetic separator to remove and thicken the medium, which may be magnetite.  Additional medium may be added either in the magnetized or unmagnetized condition.

Filed: 1971-04-19
Abstract: 1321144 Magnetic transducers INTERNATIONAL BUSINESS MACHINES CORP 19 April 1971 [9 March 1970] 23177/71 Heading G5R A transducer comprises a loop conductor embedded in a core of monocrystalline ferromagnetic zinc ferrite grown on a monocrystalline substrate. In the process illustrated, a nickel or manganese ferromagnetic zinc ferrite layer 12 is grown in each unmasked zone 11 of a Spinnell or sapphire monocrystal substrate 10 and is then partially metal coated in the form of loops 14 (Fig. 1b); a further ferrite layer (19, Fig. 2, not shown) is then grown in each zone 11 such that the loops 14 become embedded and the two ferrite layers are continuous in the non- metal coated part of the first layer. The assembly is then faced along a line 16 to produce a series of heads in which the air gaps are defined by the thicknesses of the metal coatings. In other embodiments (Figs. 2-6, not shown), similar structures are formed by either selectively diffusing nickel or manganese into non- ferromagnetic zinc ferrite layers to make the selected areas ferromagnetic, or by diffusing zinc to make ferromagnetic areas non-ferromagnetic.

Abstract: 1,108,930. Continuous casting-machines. COMMISSARIAT A L'ENERGIE ATOMIQUE. 26 May, 1966 [3 June, 1965], No. 23668/66. Heading B3F. Apparatus for continuous casting refractory metallic materials e.g. uranium carbide, comprises an electron beam gun 1 for melting granular material 26 fed into a mould formed by grooves 7, 9 of rotating pulleys 6, 8 and an axially movable base or plunger 4. The rotating pulleys prevents the accumulation of an undesirable layer on the mould surface and the grooves may be brushed or scraped as they are rotated to further prevent this. To ensure good distribution of the granular material in the mould the mould may be rotated about the axis of the plunger 4 by means of a motor 30 and gears 29, 31 driving a base 20 on which the pulleys 6, 8 are mounted in end-plates 18 and on water-cooled shafts 14, 16. The pulleys 6, 8 may be connected to pinions (17), (19) (Fig. 2, not shown) connected to each other and to the plunger 4 by a double-sided rack 25 and driven synchronously by a motor (23). The grooves (33), (35) (Fig. 3, not shown) may include projections (36) that notch the cast ingot at regular intervals so that the ingot can be broken into equal lengths.

In the embodiment of Fig. 7 the tool blade 9, carrying a tool point 17A and a wear bar 11, is pivoted on a pin passing through aligned holes 15 in the tool blade 9 and attachment plates 12, and mounted at a rearward angle by passing a sheer bolt through the upper hole 23 and aligned holes in the attachment plates. The wear bar 11 may alternatively be mounted at a forward angle by passing the sheer bolt through the lower hole 23. The tool blade 9 may also be provided with two alternative pivot pin holes, Fig. 3 (not shown), to allow the wear bar 11 to assume forward or rearward angles. In a further embodiment, Fig. 9. the wear bar may be mounted on the forward or rear edge of a tool blade 9 which is reversibly mountable on the attachment plates by a pivot pin and sheer bolt through holes 15A, 16A or 15B, 16B respectively.

Title: A road signal for avoiding dangers in vehicular traffic
IPC: G08G1/09
Filed: 1922-09-01
Abstract: 204,494. Bonkem, H. G. Sept. 1, 1922. Road signals.-In a signalling device for giving warning of the approach of vehicles at cross-roads &c., the actuating arrangement comprises two overlapping hinged plates 1, 2 which are normally held slightly above the road surface by weighted levers 28, 29 to which they are secured by links 30, 31. Passage of a vehicle causes turning of a pivoted sector 36 on a shaft 33 through rods 35 attached to the lower plate 2 and levers 34, thereby raising the semaphore arm 3 bv means of a cable 18 and a chain 6 which are connected through a multiplying lever 16. The arm 3 returns to normal in a definite time, determined by a dash-pot or by means of a ratchet 8 on its shaft which drives a pinion 10 through a pawl 11 thereon, under the control of an escapement. The multiplying lever 16 has a counterweight 17, so that the slack in the cable 18 is taken up by the chain 6. Thrust rods may be used in place of cables. The Provisional Specification mentions the use of springs in place of weighted levers, and springs may also be inserted in the transmission cable to avoid sudden action.

Abstract: 316,680. Nordfalk, L. A. E. Aug. 2, 1928, [Convention date]. Supplying consuming devices. - Discharge. tubes, such as neon lamps, are supplied from d.c. or a.c. sources and controlled by highfrequency oscillations from a transmitting valve, the anode circuit of the valve and the feeding circuit of the tubes being independently connected across the supply source so that the tube current does not pass through that valve. Amplifiers may be arranged between the transmitting valve and the tubes and to prevent' capacity changes due to alterations in the number or type of tubes connected affecting the transmitting valve a transformer may also be interposed. Fig. 1 shows a transmitting valve a the anode and grid circuits of which are inductively coupled by windings v, u and inductances e, f in series with the tubes g and the supply source h are also inductively coupled therewith to add their stepped-up voltages to the supply voltage. Tappings on one or both inductances may be provided to give a variable supply voltage' for the tubes. Fig. 2 shows two amplifiers a controlled by the transmitting valve a and energizing a transformer n from which the tubes are supplied. The capacity and inductance of the grid condenser of one of the valves may be adjusted so that the condenser charge and discharge times correspond exactly with the lighted and extinguished periods of the tubes.
