Title: Improvements in or relating to Electric Circuit Arrangements for Identifying Marked Feeder Lines in Telecommunications Exchange Systems.
IPC: H04L12/52
Filed: 1968-04-10
Abstract: 1,164,954. Automatic exchange systems. SIEMENS A.G. 10 April, 1968 [12 April, 1967], No. 17165/68. Heading H4K. An electronic line finder comprises a cascade of stages each of which comprises two OR-NOR gates which are so interconnected that if a marking denoting a calling line is present on one of the gates when a stepping potential occurs on the other gate then the output of the latter is inhibited so as to prevent further stepping and an output signal indicative of the stage and hence of the identity of the line associated therewith is given. The finder is of particular use in a code-multiple telegraph exchange. When a large number of subscribers are involved, a separate cascade is provided for each digit position of the line's number. Operation.-The two gates referred to above have the references 1b(-6b) and 1c(-6c) in the hundreds, tens and units cascades. A start potential from central control is applied to terminal F and used to set bi-stable iE provided that none of the units gates 1b-6b is marked (this will be so if a hundreds and tens identification has not taken place). Normally the output from iE then sets iZ so that hunting can take place in the hundreds cascade. If in the latter, gate 2b say, is marked then the hunting potential injected by NOR gate f is stopped by gate 2c and an output signal is provided by 2d. A selector device (not shown) then causes one of the tens stages to be marked and the output from the marked hundreds stage is used inter alia to reset iZ and to start hunting in the tens cascade (via NOR gate e). A process similar to that in the hundreds cascade takes place and finally yet another similar sequence of events occurs in the units cascade. In the latter an output from the marked output gate 1d(-6d) is applied via NOR gate h to central control to denote the end of hunting.

Title: Lithium greases
IPC: C10M169/00
Filed: 1953-06-24
Abstract: A lubricating grease, stable at high temperatures, comprises a major proportion of a lubricating oil, a minor proportion of a lithium soap of C12 to C24 aliphatic carboxylic acids, and at least 0.6 weight per cent, based on the total composition, of free lithium hydroxide.  The lubricating oil may be a mineral or synthetic oil, while suitable lithium soaps are lithium stearate and lithium hydroxy-stearate.  The grease may contain additional ingredients such as tackiness agents, viscosity index improvers, anti-corrosion agents, oxidation inhibitors and extreme pressure agents.  In the preparation of the grease, stearic or hydroxy-stearic acid may be dissolved in hot lubricating oil, sufficient lithium hydroxide added to neutralize the acid and provide the desired excess of lithium hydroxide, the mixture dehydrated at about 280-320 DEG  F., further lubricating oil added, the grease melted by heating to above 400 DEG  F., and finally the grease cooled.  The cold grease may then be homogenized but in the case of hydroxy-stearate greases it is desirable to stir the molten grease into a grease mixer and to pass the cold grease through a grease mill.  In examples, some of which are for comparison purposes, lubricating greases are described which consist of mineral lubricating oil, lithium stearate or lithium 12-hydroxy-stearate, lithium hydroxide and/or lithium carbonate, and phenyl alphanaphthylamine.
