Abstract: 214,273. Torrilhon, H. M. Lamy-. April 14, 1923, [Convention date]. Purifying fats and fatty oils; essential oils and turpentine; extracting. -In refining substances or removing volatile ingredients the substances are subjected to successive treatments with steam or vapours under different pressures generated in the different effects of a multiple-effect evaporating-apparatus. As applied for deodorizing oil by treatment with steam, the oil is passed down a column divide'd into sections 1, 2, 3, separated by chambers containing heaters 10, 11. Each section contains perforated plates 4 .. 9, and is supplied with steam by pipes 13, 14, 15 from the effects 16, 17, 18 of a three-effect evaporator. The steam from section 1 passes by a pipe 19 to the heater 17<a> of effect 17, the steam from section 2 by a pipe 20 to the heater 18<a> of effect 18, and the steam from section 3 passes by a pipe 21 to a barometric condenser 22 which is exhausted by a pump or a steam ejector 23, the steam from which passes into the heater 16<a> of the effect 16. Alternatively, the condenser 22 may be exhausted by two ejectors 23<1>, 23<11> in series separated by a surface condenser 32 in which water for evaporation may be preheated. The condensed water from the heaters 16<a>-18<a> is passed through preheaters 26-28 for the feedwater or mav be passed through steam traps into the heater below. The treated oil from the base of the column is passed through a preheater 24 for the oil supply. For treating solid matter, such as for extracting turpentine from pinewood sawdust or oil from sandal wood, the column is replaced bv an apparatus which allows the solid's to fall from one plate to another. Rotary valves may be employed to separate the sections.

Filed: 1928-03-28
Abstract: 314,463. Standard Telephones & Cables, Ltd., and Wright, E. P. G. March 28, 1928. Automatic exchange systems. A code-translating register controller is designed to deal with single-letter and two-letter name codes, the single-letter offices having one or more thousands groups (corresponding to the second letters of the twoletter offices with the same first letter) omitted. Relay A repeats the digits over a dialling relay C which energizes the back stroke magnet DD of the digit distributor. If the first two digits are those of a two-letter office, the register controller operates in the ordinary way. In the case of single-letter offices, however, a circuit is made over an extra wiper 1 on the office register W for CR which locks up, causes DD to skip its 3rd position and the thousands register M to move to the position marked by a further additional wiper 2 where it is stopped by CS. Alternatively wiper 2 may be made to control transmission of the thousands digit directly, in which case CR initiates transmission of the route code, which in the arrangement shown waits for the thousands register to move off-normal.
