Title: Improvements in or relating to liquid level gauges of the transparent prism type
IPC: G01F23/02
Filed: 1931-10-08
Abstract: 387,425. Indicating liquid-levels. ELECTRICAL IMPROVEMENTS, Ltd., Carliol House, Newcastle-on-Tyne, and BLACKBURN, C. L., 2, Ryder Street, London. Oct. 8, 1931, No. 27969. [Class 12 (i).] A liquid-level gauge comprises a prism so arranged that light entering the gauge above the liquid is totally reflected so that the upper part appears dark, while light entering below the liquid level is refracted through the liquid so that the lower part appears bright. In Fig. 1, two similar glass prisms A, B are mounted vertically with their inclined faces separated to form, with internal shoulders D<1>, a space for the water column. The prisms are clamped in a casing D against inset pieces E, E<1>. Light is directed through the opening E<2> and is incident on the oblique surface of the prism at an angle to the normal greater than the critical angle for the upper part, and less than the critical angle for the lower part of the surface in contact with the liquid. The upper part of the beam is thus totally reflected, while the lower part is refracted and passes through the second prism to emerge at E3. In a modification, Fig. 3 (not shown), the prisms are mounted in a recess in the casing and are secured by a slotted cover-plate held by screws. In another modification, Fig. 6 (not shown), one of the prisms is replaced by a parallel-sided glass plate, and the light may be incident from either side.

Patent GB-1109128-A (GB)
Title: A method of purifying a flowing gas and apparatus for performing the same
IPC: B01D46/30
Filed: 1965-07-01
Abstract: Gaseous acidic contaminants, e.g. CO2 are removed from gaseous mixtures containing them by passing the mixture through a filter element containing at least one alkali filter body said filter body, prior to its contact with the gaseous mixture, containing water but in an amount not exceeding 5% by weight, and being reactivated when exhausted by heating at a temperature such that the surface layers of the body rupture to expose fresh absorbing surface but substantially none of the previously absorbed acidic gas is released, each reactivation step employed being conducted at a temperature higher than the previous one. Preferably the filter bodies consist of Ca(OH)2 and the working absorbing temperature of the filler body is between 100 DEG  and 200 DEG  C. and the reactivation temperature ranges in successive steps from 250 DEG  to 400 DEG  C.  A suitable on line arrangement is depicted in the figure utilizing two filter elements 3 and 4, arranged in parallel, one 3 being in use while the other 4 is regenerated, the elements being maintained at working temperatures or reactivation temperature by heating elements 32 and 42.  When detector 14 in outlet pipe 6 detects the acidic gas, i.e. CO2 breaking through element 3, controller 13 changes over two-way valve 5 and simultaneously operates switches 10 and 11 so that the heating elements 32 and 42 are connected to voltages suitable for their working or regeneration phase.  Contact thermometers 33 and 43 are fitted in the heater circuit so that when the temperature of the absorbent reaches a specified upper limit, the current is cut-off. In the regeneration phase, at this temperature, the contact is not remade so the regenerated bed slowly cools.  The vessel 7 is a water filter which removes water from the gas and dries it. It may be heated under the control of thermometer 72 and switch 12.  Its specified operating temperature is 110 DEG  C. and its specified packing is CaO + Ca(OH)2.

Abstract: 358,257. Reversing valves for regenerators &c. WOHLFAHRT, S., Fagersta, Sweden. Sept. 23, 1930, No. 28497. [Class 51 (i).] Reversing apparatus for regenerative furnaces &c. comprises two valves, one closing upwardly and the other downwardly, suspended on a single operating cable so that the upwardly-closing valve is held closed by the weight of the other valve so long as it is open and can only open when the downwardly-closing valve closes or comes against a stop. As shown applied to the produce-gas supply to an open hearth furnace sliding valves 1 in the chimney flue 3 rest on sloping frames 2 and are raised or lowered by rods 4 each connected by a rope 5 running over pulleys 6, 7, 8 to the operating pulley 9 the free end of the rope being provided with a counterweight 10. The pulleys 6, 8 are fixed while the pulley 7 carries by a rod 11 a beU valve 12 closing upwards against a seat 13 in the gas pipe 14. Passages 15 lead to the regenerator chambers of the furnace and in the position shown producer gas from the pipe 14 passes to the lefthand regenerator while waste gases pass under the right-hand valve 1 to the chimney. The valves 1 are made more than half as heavy as the valve 12 so that when the operating pulleys 9 are turned the valve 12 must be closed before the valve 1 can be opened. The amount of opening of either valve may be regulated by the operating pulleys 9 when the other valve is in its closed position. Should the rope 5 or the rods 11 or 4 break the valve 12 drops on to a lower seat 16, preventing loss of gas. The two valve groups may be operated by a common pulley. A number of valves 12 may be provided in such a manner that the valve 1 will not open until all the valves 12 have been closed. The bell valves may be replaced by hinged or sliding valves.

Filed: 1927-10-27
Abstract: 280,520. Bakelite Corporation, (Assignees of Bender, H. L.). Nov. 10, 1926, [Convention date]. Condensation products of formaldehyde with phenol and urea, thiourea, or toluene p-sulphonamide.-Resinous products are obtained by causing a phenol to react with more than one molecular proportion of formaldehyde, and then combining at least a part of the excess of formaldehyde with a non-phenolic substance having resin-forming properties; instead of formaldehyde, its polymers or equivalent substances, such as hexamethylenetetramine, may be used. In an example, phenol and an excess of formaldehyde solution are heated in presence of sodium carbonate or other basic catalyst until separation of water occurs, and the heating is continued, preferably under reduced pressure, until the water is evaporated. The product is then treated with urea and with sufficient lactic, boric, phosphoric or other acid to render the mass acid, and is finally heated again. The product may be rendered infusible and insoluble by further heating and may be used in making moulding mixtures, or alternatively it may be dissolved in alcohol or other solvent, the addition of which may precede or follow the addition of the urea, and used as a varnish. Instead of urea there may be used thiourea or toluene p-sulphonamide. The Specification, as open to inspection under Sect. 91 (3) (a) states that instead of urea there may be used homologues of urea or urea derivatives other than thiourea. This subject-matter does not appear in the Specification as accepted.
