Title: Improvements in or relating to circuit arrangements for characterising the origin oftrunk dialling calls in central evaluating arrangements
IPC: H04M15/10
Filed: 1960-06-08
Abstract: 925,817. Automatic exchange systems. SIEMENS & HALSKE A.G. June 8, 1960 [June 16, 1959], No. 20161/60. Class 40 (4). In a trunk-dialling system in which a destination code number is arranged to be converted into different zone-characterizing metering signals in combination with criteria characterizing the origin of a call in registers Sp1, Sp2 and translating devices UmW located at a central exchange KA, the arrangement is such that when the code number determining the destination centre is fed from a register Sp1 or Sp2 into a common translator UmW, a criterion is simultaneously transmitted from the register to the translator through the metering impulse sender ZJG1, ZJG2, or ZJG3 associated with the call and through the selector IGWA, MWB, or MWC by which the metering impulse sender is seized (and, as shown, through a corresponding marking lead Ya, Yb, or Yc, respectively), which criterion pertains to the selector group accessible from the centre originating the call, which may be the central exchange KA or a terminal exchange such as EAB or EAC. Evaluation of the metering rate thereby takes into account both the destination code number and the place of origin of the call, preventing overcharging for calls between adjacent terminal exchanges which happen to be connected to different central exchanges.

Filed: 1953-07-25
Abstract: 734,330. Mixing-appliances. LINTAFOAM INDUSTRIES, Ltd. July 25, 1953, No. 20710/53. Addition to 694,284. Class 86. The apparatus of the parent Specification for the manufacture of foamed latex, is modified in that the proportion of latex to air is determined ' by the level of latex maintained in a latex supply tank 23, the proportion of latex to air increasing as the level of latex in the tank 23 is raised. The rate of delivery of foamed latex is determined by the rate at which air is supplied to the foaming apparatus. The means for regulating the level of latex in the tank 23 comprises a vertically adjustable electrode 33, an electronic tube switch device 32 and a solenoid valve 30, 31 which controls the air supply of a pneumatically operated valve 25 in a flexible latex supply pipe 24. The latex flows from the bottom of the tank 23, along a pipe 17 and into the lower end of the conical shell 16 of the foaming apparatus, from the upper end of which the foamed latex is discharged. The air is supplied through a control valve 22 and gauge 21 and enters the foaming apparatus through a pipe 18. An increase in the rate of air supply reduces the back pressure exerted by the latex in the foaming apparatus upon the latex in the tank 23, causing the level of latex in the tank 23 to fall, thus correspondingly increasing the rate at which latex is supplied through the pipe 24, and hence correspondingly increasing the rate of delivery of foamed latex having the proportions determined by the setting of the electrode 33.

Title: Process for the manufacture of primary alcohols

Filed: 1928-07-17
Abstract: 320,424. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). July 17, 1928. Alcohols.-Primary alcohols are obtained by treating an alkylene oxide containing the group R<1>-CR-CH2 (R being a hydrogen atom, an \O/ alkyl, aryl or aralkyl residue, and R<1> an alkyl, aryl or aralkyl residue) with hydrogen in the presence of a hydrogenation catalyst, in particular finely divided metals of the eighth group of the periodic system. The catalysts may be used singly or in admixture or in conjunction with a carrier, and their effect may be enchanced by the aid of a promoter e.g. an alkaline acting agent, aluminium oxide or thorium dioxide. The process may be carried out in liquid or vapour phase, with or without pressure, the temperature being selected to prevent decomposition of the oxide and resulting alcohol. Mixtures with alkylene oxides of a secondary tertiary nature may also be treated. According to examples, (1) nickel nitrate is precipitated with caustic soda, filtered, washed first with water and then with dilute caustic soda, and the precipitate dried. It is then reduced by hydrogen at 250‹-300‹ C., and then a mixture of hydrogen and propylene oxide is passed over at 170‹ C. N.propyl alcohol is obtained. (2). A nickel catalyst, precipitated with calcium carbonate and then reduced, is used for the conversion of a mixture of a- and #- butylene oxides at 170-180‹ C. A mixture of n-butyl and secondary butyl alcohol is obtained, which is separated by fractional distillation. (3) Copper nitrate is precipitated with caustic soda, washed, dried, reduced and then used as a catalyst to convert a mixture of alpha- and #-butylene oxides at 170-180‹ C. Primary and secondary butyl alcohol is obtained. (4) A mixture of hydrogen and styrene oxide is passed over a nickel catalyst prepared according to example 2, but containing a little calcium hydroxide. The condensed product contains #- phenyl ethyl alcohol and traces of phenyl acetaldehyde. Specification 27963/13, [Class 1 (i), Chemical processes &c.], is referred to.
