Filed: 1926-05-27
Abstract: 253,881. ChÛneau, L. J. J. B. June 19, 1925, [Convention date]. Fire-alarm systems and apparatus; falling-flap indicators.-In a signalling system, such as a fire alarm system, wherein a number of contacts located at different places are associated with a corresponding number of indicator devices, the indicator devices may be assembled to form a single unit. As shown in Fig. 8, heatsensitive contacts 1 are assosiated with a corresponding number of self-contained falling-flap indicators 2 assembled between end-plates 19, 20 to form a single unit. Each indicator is provided with contact strips 16, 17, 18 having upturned ends and the corresponding strips are adapted to engage one another so as to electrically connect the units in parallel. Normally the contacts 1 close circuits for the electromagnets over terminal 24 and strips 17. When, however, a contact 1 is broken due to the action of heat the corresponding electromagnet 4 is deenergized to allow the armature 7, which is eccentrically mounted on a pivot 8, to fall. A spring tongue 11 which normally exerts a pressure upon the armature, is released to complete the circuits of the lamp 14 and a bell 33 at contacts 9, 10. The lamp 14 illuminates a number, which is appropriate to the operated contact device 1. Fig. 1 shows a single unit mounted between the end plates 19, 20. The end plates are held in position by screws 21, and the battery and bell are connected to the indicator by contacts 25, 29, 30 which engage the strips 17, 16, 18 respectively. In Fig. 2, which shows a section through an indicator, the circuits of the lamp 14 and the bell are compelted by a spring controlled member 11 which slides along the pole piece 5 of the electromagnet 4 when the armature 7 is released to display the legend upon the glass front 15. The indicators are supported on a panel by screws passing through lugs 3. A number of contacts 1 may be associated with a single indicator. Specification 239,532, [Class 47 (i), Fire-escapes &c.], is referred to.

Title: Fumigating mixtures containing hydrocyanic acid and process for their production
IPC: C01C3/02
Filed: 1927-05-23
Abstract: 271,514. Deutsche Goldund Silber- Scheideanstalt vorm. Roessler. May 22, 1926, [Convention date]. Fumigants. - Liquid hydrocyanic acid to be used for fumigation is treated with gaseous chlorine so that about five per cent of cyanogen chloride is formed and serves as an irritant warning substance when the hydrocyanic acid is used. The chlorine is passed in a rapid stream into cooled hydrocyanic acid containing from two to six per cent of water. Hydrochloric acid formed is removed by carrying out the reaction in presence of excess of oxides, hydroxides, carbonates or bicarbonates of non-alkaline reaction, for instance aluminium oxide or hydroxide, zinc oxide, calcium or magnesium carbonate, and sodium bicarbonate; or these substances may be added after the reaction is complete. The liquid mixture of hydrocyanic acid and cyanogen chloride is separated by decantation from such additional substance and may be stabilized by means of acids or acid substances. The Specification, as open to inspection under Sect. 91 (3) (a) states also that the liquid mixture produced may be absorbed into porous substances such as diatomite or silica gel. This subject-matter does not appear in the Specification as accepted.

Title: Process and apparatus for effecting vapour-phase reactions with finely divided solid catalysts
IPC: B01J8/00
Filed: 1954-05-13
Abstract: <PICT:0749222/III/1> Vapour phase reactions in the presence of a finely divided catalyst are carried out by fluidizing a bed of the catalyst in zone 1 by means of a diluent gas entering at 2, introducing reactant vapours at 3 and passing them, together with suspended catalyst particles, up through narrow reaction zone 6 to centrifugal separator 7 from which catalyst returns via line 8 to the fluidized bed; the ratio of catalyst to reactant vapours in the reaction zone varies according to the level of the fluidized bed in zone 1 which is regulated by withdrawing catalyst at 10 or by addition of catalyst from storage vessel 9 via line 11.  A grid 4 is arranged between the top of the fluidized bed and the reactant vapour inlet.  Reaction products leave at 16.  For exothermic reactions, cool diluent gas is used, so that the catalyst is maintained below reaction temperature; for endothermic reactions, the diluent gas is preheated.  The gas velocity may be 2-5 feet per second in zone 1 and 25-50 feet per second in zone 6.  Dehydrogenation of naphthalenic hydrocarbons may be carried out, using a platinum on alumina catalyst, and hydrogen as the diluent gas.  Oxidations, hydrogenations, and pyrolyses may also be performed, other specified diluent gases being flue gas, carbon dioxide, carbon monoxide, water gas, methane, nitrogen, and steam.
