Title: Improvements in apparatus for calling attendants and for like purposes
IPC: G08B5/22
Filed: 1945-08-23
Abstract: 605,720. Indicators for summoning attendants; electric selective signalling systems. PHOENIX TELEPHONE & ELECTRIC WORKS, Ltd., and DOWNING, H. F. Aug. 23, 1945, No. 21608. [Classes 40 (ii) and 118 (ii)] [Also in Group XXXVII] A signalling device for calling attendants, indicating the point of origin of the call, and extinguishing the calling signal, comprises an electric lamp which, or the globe of which, is spring- supported so that when depressed it closes an associated switch and then rises again, and when next depressed opens the said switch. A lamp 4 is covered by a globe 3 mounted on a holder 6, a collar 8 of which is held against a face-plate 2 by a spring 7. Depression of the globe 3 causes a spring-mounted pawl 9 to rotate a square prism 14 through 45 degrees to close contacts 16, as shown, and light a distant indicating lamp in a service room or the like, and also light the calling lamp 4. The return stroke of the pawl 9, when the globe 3 rises, is idle and the lamps remain alight until the globe 3 is again depressed either by the caller or the answering attendant, and the prism 14 allows the contacts 16 to open. An insulated roller 19 may be provided to bridge contacts 17 so long as the globe 3 remains depressed and so sound a short audible warning in the service room. Instead of each calling station having its individual indicating lamp in the service room, one common lamp may be provided. If it is desired that the lamps be extinguishable from the service room, a second prism 28 is provided to close contacts 29 when contacts 16 are open and vice versa and a number of devices similar to that described are provided at the service room. These devices may comprise, instead of a lamp, a push-operated flag, shutter or like signal. The contacts 16, 29 are wired so as to connect positive or negative battery alternately to the lamp 4 and the distant indicator upon each depression of a globe 3. The calling lamp 4 and service room indicator may be in parallel or, preferably, in series. The addition of extra contacts may provide for lighting additional lamps and for extinguishing the calling signal from the location of such additional lamps. The switch 14, 16 or 28, 29 may be in the form of a drum of insulating plastic with contacts on its surface co-operating with contact springs bearing thereon. The Provisional Specification states that the calling station may comprise, instead of a lamp, any other push-operated signal.

Abstract: 155,020. Vakil, K. H. Sept. 9, 1919. Fats and fatty oils, purifying.-Vegetable, fish, and animal oils and fats are deodorized and refined by bringing them at temperatures between 220‹ and 300‹ C. into intimate contact with carbon dioxide alone or mixed with nitrogen, the free fatty acids and other odoriferous substances thus being volatilized. The oil is heated to the requisite temperature by passage through a heat-exchanger 2 and an electric heater 3, and is led through a distributing-pipe 6 to a refining-tower 5 in which it meets an ascending current of carbon dioxide, heated, if necessary, by a heater 8. A rotary pump 4 is provided for circulating the partly-refined oil. The carbon dioxide together with the volatilized fatty acids passes through a separator 9 to a heat-exchanger 10 and thence after admixture with steam in a jet 11 to a second condenser 12. The fatty acids are condensed and collected in receivers 23, 24. The gases may be scrubbed with oil in a scrubber 14, and are either led to a gas-holder or are returned through heat-exchangers 19, 10 to the tower 5. The prior use of temperatures of 110-220‹ C. and 350-400‹ C. is referred to.

Abstract: 1422423 Separating acidic gases IMPERIAL CHEMICAL INDUSTRIES Ltd 11 April 1974 [10 May 1973] 22356/73 Heading C1A [Also in Division G3R] A process for separating an acid gas from a gaseous mixture by absorption in an alkaline solution comprises the steps of (A) measuring the corrosion potential of a metal surface in contact with the absorbing solution (i.e. the electro-chemical potential relative to a standard reference scale, or a parameter affecting that potential and, when the potential is indicated as being below a prescribed value, (B) adding to or generating within the absorbing solution an ionic species capable of increasing the redox potential to an extent sufficient to raise the corrosion potential above the prescribed value. The object is to prevent corrosion cracking of the mild steel vessels used. In the embodiment the absorbing solution is of potassium carbonate and contains arsenite/arsenate ions. Preferably direct "corrosion monitors" are used but alternatively the content of an ionic species, e.g. ferric ion, is measured. The potential at which cracking may occur depends upon the "carbonation index" (defined in the Specification) and the prescribed value is 20 mV. above the value appropriate to this index (examples are given). The potential is raised by adding ferric, antimony or vanadate ions. Ferrous, ferric and antimony ions may be always present in the solution and the adjustment may be effected by blowing air through the solution to oxidize the ferrous to ferric ions. A specific example is given. In the Figure rich absorbing solution containing acid gases absorbed in 1 is pumped to the top of a regenerator 2, whilst regenerated or "lean" solution is pumped from the base of 2 to the top of 1. Semi-lean solution is pumped from 2 to 1 along pipe 5. 6, 7 and 8 are corrosion monitors; when the signal from any one indicates the prescribed value is reached air is admitted at.9. This operation may be automatic or manual.
