Patent GB-755488-A (GB)
Title: Lubricating greases
Filed: 1954-10-04
Abstract: A lubricating grease comprises a major proportion of a lubricating oil which is thickened with an alkali metal soap of a fatty acid containing 12 to 36 carbon atoms, and a minor proportion of a mixed polyvalent metal soap of a hydroxy fatty acid containing at least 10 carbon atoms and a naphthenic acid or a mixture of polyvalent metal soaps of a hydroxy fatty acid containing at least 10 carbon atoms and of a naphthenic acid. The alkali metal soaps are sodium, potassium and lithium soaps of lauric, myristic, palmitic stearic, arachidic, behenic, oleic and linoleic acids.  The polyvalent metal soaps are derived from magnesium, calcium, strontium, barium, aluminium zinc, tin, iron, lead, zirconium, titanium and chromium.  The hydroxy fatty acids from which the polyvalent metal soaps are derived are 9-, 10-, 11- or 12 - hydroxystearic acids, 10- and 15-hydroxypalmitic acids, hydroxy myristic acids, hydroxy behenic acids, 5, 6-, 6, 7-, 7, 8-, 8, 11-, 9, 10- and 10, 11- dihydroxystearic acids and 2, 11-dihydroxypalmitic acid; examples of soaps from these acids are aluminium 12-hydroxystearate, zinc 12-hydroxystearate, aluminium 10-hydroxypalmitate and chromium 15-hydroxypalmitate. Suitable naphthenic acids are derived from petroleum oils, and resin acids such as abietic acid; an example is calcium petroleum naphthenate. Examples of mixed soaps are the calcium soap of equi-molecular proportions of 12-hydroxystearic acid and petroleum naphthenic acids, and the aluminium soap of a mixture of 1 mol of 10-hydroxystearic acid with 2 mols of petroleum naphthenic acids.  The greases contain 0.1 to 2.5 per cent by weight of each polyvalent metal soap when a mixture is used, and 0.2 to 5 per cent by weight when a mixed polyvalent metal soap is used.  The lubricating oil may be a mineral oil, or a synthetic oil i.e. polymerized olefins, polyalkylene oxides, such as polypropylene oxide, polymerized sulphides such as polypropylene sulphide, polymerized glycols, such as polyethylene glycol, esters of dicarboxylic acids such as bis (2-ethylhexyl) sebacate, esters of acids of phosphorus, such as tricresyl phosphate, phthalates, such as dibutyl phthalate, alkyl silicates such as tetra (2-ethylhexyl) silicate, silicone liquids, or fluorocarbons. Examples describe mineral lubricating oil thickened with lithium stearate, to which is added calcium naphthenate and aluminium 12-hydroxystearate. Specification 742,517 is referred to.

Abstract: 1394993 Integrating voltage with respect to time FERRANTI Ltd 7 June 1972 [18 June 1971] 28594/71 Heading G1U [Also in Division H3]  A device for producing a number of pulses proportional to a voltage-time product and directing the pulses to one of two registers depending on the input voltage polarity comprises two alternately operated FET switches 12, 14 which switch the voltage (a) both directly and inverted (at 15) to integrator 17 which generates a ramp, a bistable circuit 21 which responds to two voltage levels and generates a pulse train which is fed both via relay contact 51 to one of registers 57, 58 and as the switching signal to switches 12, 14 and a relay 61 which, on a change of input polarity, operates its switches 51, 42 to switch the pulses to the other of the two registers 57, 58 and to reverse the order of switching pulses to switches 12, 14. The non linear network 33, 34, 35 following inverter 15 ensures a high gain discrimination of the zero crossover of the input signal and hence an accurate response of relay 61. The operation of switch 41 by a change in input polarity causes a second polarity reversal at'the integrator input and maintains the directions of the ramp input. An output square wave signal can be derived from the contacts 45 of relay 44 operated by the switching signal.

[Class 80 (iv).] In a rotary pump or compresser of the kind comprising a working system, a driving system, and a casing system which encloses the working and driving systems and is adapted to swing about a point of suspension so as to induce a circular motion of a piston forming part of the working system, the driving system includes eccentrically mounted masses which are so arranged that the instantaneous centre of initial rotation of each individual system due to the forces exerted thereon by the other systems approximately coincides with the instantaneous centres of initial rotation of the other systems and with the point of suspension, so that during operation of the machine there is substantially no reaction at the point of suspension other than that due to gravity. In the form shown in Figs. 1 and 2, the casing 1 encloses an electric motor 2, the shaft 11 of which carries weights 15, 16 angularly displaced by 180‹ from each other, and a compresser chamber 3, which is formed with a cylindrical bore 18 communicating with inlet and outlet passages 19, 20 and containing a piston 24 provided with " flywheel " members A, B, at its opposite ends. A sliding abutment member 27 is pressed into contact with the piston 24 by a spring 28 while a non-return valve 29 is disposed in the outlet passage 20. The casing 1 is suspended from supports 5, so as to swing with a circular pendulum movement about the point 4, by flexible metal strips 7 secured to lugs 9 on a ring 8 which, in turn, is connected to the casing 1 by further flexible metal strips 7a. A modification is described in which the motor 2 and shaft 11 are replaced by a shaft carrying a single weight 15 and driven from an external source of power by means of belting and a pulley mounted obliquely on its upper end. Fig. 4 shows a further construction in which the compresser chamber 67 is rotatably mounted within the casing 55, being connected thereto at its lower end by a universal joint 71 and having its upper end 68 mounted in a bearing 69 arranged eccentrically in the weight 66 carried by the motor shaft 64.

[Also in Group XXXVI] A pulse rate measuring circuit wherein a gas triode is triggered by each pulse and responsively a capacitor is discharged and re-charged and a meter measures the average charging current as a function of pulse rate utilizes a hotcathode type of gas triode. In the embodiment shown each pulse from a G.M. counter tube 2 triggers a hot-cathode gas triode 7 to discharge a capacitor 11 through a resistance 13 until the gas triode extinguishes. The charge on capacitor 11 is replenished through resistances 15, 16 and a microammeter 17 which indicates the pulse rate. The resistance 16 is shunted by a capacitor 18 and the meter 17 reads the mean charge replenishing current over a period of e.g. three seconds. The range of the rate of count is changed by selecting an appropriate capacitor 11 by means of switch 12. The micro ammeter 17 also serves as a calibrating voltmeter and facilitates the correct setting of supply potentiometer 20. Specification 699,401 is referred to.
