IPC: C11D1/72
Filed: 1950-05-08
Abstract: A free-flowing detergent powder is obtained by dehydrating a salt containing water of crystallization slowly at a temperature below its transition temperature, in the presence of a detergent which is a liquid or a waxy solid at normal temperatures. Suitable hydrated salts include sodium metasilicate with nine molecules of water, magnesium sulphate with seven molecules of water, sodium sulphate, sodium borate, sodium pyrophosphate or sodium carbonate, all with ten molecules of water, disodium hydrogen phosphate or sodium orthophosphate with twelve molecules of water, ammonium alum with 24 molecules of water and naturally occurring salts such as trona and urao (Na2CO3 . NaHCO3 . 2H2O) and gaylussite (Na2CO3 . CaCO3 . 5H2O). The proportion of detergent in the mixture may vary between 5 and 40 per cent. by weight.  The preferred detergents are the condensation products of alkylated phenols with from 5 to 20 molecular proportions of ethylene oxide, the alkyl substituents preferably containing in all between 6 and 20 carbon atoms.  These condensation products are described in Specification 470,181.  Other detergents specified are the condensation products of ethylene oxide with fatty alcohols, e.g. cetyl alcohol, sperm oil alcohol, and dodecyl alcohol, with fatty acids such as stearic, oleic and lauric acids and acid mixtures derived from coconut oil, or with fatty acid amides; the methyl taurine derivative of oleic acid; secondary alkyl sulphates; quaternary ammonium compounds such as the alkyl pyridinium chlorides; sulphonated petroleum derivatives such as mahogany sulphonates; and sulphonated esters, e.g. sulphonated oleic esters or sulphonated castor oil.  Other substances which may be incorporated in the mixtures either before or after the dehydration include inorganic salts such as carbonates, sulphates, phosphates, borates and silicates, acid salts, lime, clays, pumice powder, montmorillonites, starches, dextrines, sodium carboxymethyl cellulose and fluorescent whitening agents or optical bleaching agents.  In an example 47.3 parts by weight of the product obtained by condensing 1 mole of p-iso-octyl-phenol with 8 moles of ethylene oxide are mixed with 322 parts of Na3SO4 . IOH2O and the mixture is heated at 30 DEG C. for 5 hours in a vacuum drum drier.  The temperature is then gradually raised to 110 DEG C. during 10 hours to obtain a free flowing powder. Many other examples are given.

Title: Improvements in or relating to automatic or semi-automatic telephone systems
IPC: H04M15/10
Filed: 1929-04-16
Abstract: 330,062. Coventry Automatic Telephones, Ltd., and Collyer, J., E. April 16,1929. Metering systems.-In a system for metering calls in which different calls are assessed at different rates depending upon the location of the called parties, a step-by-step switch which is common to a plurality of selectors is adapted during one cycle to supply a different number of impulses to each of a group of leads so that by selection of the lead appropriate to the call, the calling party's meter may be operated the requisite number of times. Fig. 1 shows part of a first selector circuit and Fig. 2 the common metering circuit. Assuming that connection has progressed as far as the ringing of the called subscriber's bell, answering by the called subscriber operates the supervisory relay D to energize relay P which locks. Relay P operates relay MS which energizes T. Relay T operates the stepping magnet 35 of switch 31 - - 34 and deenergizes MS, which releases magnet 35 and thus moves the switch one step. Relays T, MS initiate the cyclic, operation of relays X, Y, Z which at contact 44 effect the continued operation of the stepping switch until after a plurality of steps relay P is released by wiper 33 to release relay MS and relay T is released over wiper 34 to prevent further stepping. The switch is now in a sub-normal position ready for use on other calls. Upon the first step of the switch a relay Q is operated over wiper 32 to extend the metering lead 14 to a vertical wiper V, which selects one of the groups of common leads 19, 20, 21 according to the setting of the selector. During operation of the switch, wiper 31 applies a different number of impulses to each lead 19, 20, 21 so that the meter is operated in a manner characteristic of the setting of the wiper V and its associated selector. If the impulsing switch is already in use when the relay P is operated upon metering, relay Q remains de-energized to prevent metering during that cycle, but at the end of the cycle, relay MS is operated to start a further cycle of operations during which metering is effected from the associated selector and from any others which may be waiting. Determina. tion of the assessment of a call may be made at a first, second or other selector or at a repeater. Specification 450/14 is referred to.
