Title: Meshed-network relay based on the ferraris principle
IPC: H01H53/12
Filed: 1967-03-14
Abstract: 1,140,285. Induction relays. SIEMENS A.G. 14 March, 1967 [22 March, 1966], No. 12006/67. Heading H1N. [Also in Division H2] An induction relay comprises a single conductive rotor on which act two or more electromagnetic systems each comprising a voltage pole between two current poles, the systems having an angular spacing about the axis of the rotor of less than 180 degrees such that interaction between the voltage poles will produce a torque opposing the main torque of the electromagnetic systems and that interaction between the current poles produce a torque assisting the main torque. Normally the voltage torque predominates but when the current increases and the voltage falls due to a short-circuit in the protected system, the resultant torque changes direction so that the rotor reverses its direction of rotation and actuates contacts.

Title: A Process for the Manufacture of Sodium and Aluminium Hypochlorites.
Inventor: DUTT ERIC EDWARD
IPC: C25B1/26
Filed: 1917-08-22
Abstract: 119,261. Dutt, E. E., and Dutt, P. C. Aug. 22, 1917. Sodium aluminate and hypochlorite; aluminium hypochlorite; arsenic trichloride.-In a process for the manufacture of sodium and aluminium hypochlorites, sodium aluminate is first produced by heating a mixture of calcined bauxite sodium chloride, calcium hydrate, and carbon to redness in a retort in a current of arsenic trioxide vapour. Arsenic trichloride, hydrogen, and calcium carbonate also are formed, the arsenic trichloride being condensed and employed for the manufacture of chlorine for use later in the process. The residue is lixiviated and the solution of sodium aluminate is divided into two parts into one of which carbon dioxide is passed until the precipitation of aluminium hydroxide is complete. The sodium carbonate is filtered off and employed for the production of sodium hydrate for subsequent use in the process. The precipitate of aluminium hydroxide is mixed with the remainder of the sodium aluminate and chlorine is passed into the mixture till all the aluminium has passed into solution as hypochlorite. The hydrochloric acid formed is neutralized with sodium hydrate solution which is added in sufficient quantity to precipitate aluminium as hydrate with production of sodium hypochlorite. The aluminium hydrate is filtered off, mixed with water and converted into hypochlorite by passing chlorine into the liquid. The sodium chloride produced is crystallized out from the solutions of the hypochlorites.
