Patent GB-717453-A (GB)
Title: Improvements in or relating to lubricating grease composition
IPC: C10M169/00
Filed: 1952-10-14
Abstract: A lubricating grease comprises a major proportion of lubricating oil and a minor proportion of a mixture of a monovalent metal soap of a substantially saturated C12-C22 fatty acid, or mixture of such acids, and a divalent metal salt of a C1-C5 carboxylic acid, or mixture of such acids.  The lubricating oil may be a mineral oil or an aliphatic dicarboxylic acid ester oil such as di-2-ethyl-hexyl sebacate.  The soap is preferably a lithium soap of a saturated fatty acid, while the divalent metal salt is preferably an alkaline earth metal salt, particularly a calcium salt, of acetic, propionic, acrylic, methacrylic, furoic or thiophene carboxylic acid.  Additives such as extreme pressure agents, oiliness agents, thickeners, metal deactivators, oxidation inhibitors (such as phenylamines, particularly phenyl alpha-naphthylamine) and plasticizers may be incorporated in the grease.  In the preparation of the grease, the soap may either be preformed and added to the oil as a dry powder or it may be formed in the mineral oil and completely dehydrated before the divalent metal salt is added as a dry powder.  Alternatively, the divalent metal salt may be mixed with the dry powdered soap and the mixture incorporated in dehydrated mineral oil.  A concentrate may first be produced and, after adding more oil sufficient to permit complete dispersion of the solids, the mixture may be completely melted and then allowed to cool.  More oil may then be added if a softer grease is desired.  The final grease may be passed through a homogenizing apparatus under high shear conditions.  In examples, lubricating greases are prepared which consist of (1) mineral lubricating oil, lithium soap of p  hydrogenated fish oil fatty acids, calcium acetate or acrylate and phenyl alpha-naphthylamine and (2) di-2-ethyl-hexyl sebacate, lithium stearate, calcium acetate and phenyl alpha-naphthylamine. The greases may contain free alkalinity.

Filed: 1971-04-19
Abstract: 1321948 Digital transmission systems; distortion correction SIEMENS AG 19 April 1971 [3 June 1970] 25908/71 Heading H4P A fortuitous D.C. bias correction arrangement for a FSK system comprisse a first amplifier V1 receiving signals from a discriminator (not shown) the output from which is fed via an inverting and limiting stage to an output terminal A, output signals from amplifier V1 and the inverted output signal being compared and forming a control signal which is filtered and fed to the input of a second amplifier V2 the output from which is superimposed upon the input signal to the first amplifier. An amplifier V3 inverts signals which are shaped and steepened in an output stage AS, but in an alternative arrangement, Fig. 4 (not shown) stage AS also inverts signals and replaces amplifier V3. A resistor R3 is advantageously replaced by series opposed Zener diodes, additional to Zener diodes Z1, Z2, which provide amplitude cut-off waveform U2, Fig. 3 (not shown). The voltages across amplifier V3 via resistors R3, R4 are combined to charge a filtering capacitor 3 and in dependence of whether this is positive or negative a corresponding output Us is injected into V1. The amplifiers are preferably of integrated form, V1 being a linear amplifier and V2 having a cut-off characteristic so that any increase in voltage Ur beyond a determined value does not increase output voltage Us which ensures that Us can never move the amplifier V1 into a non- linear range. An additional control stage, Fig. 5 (not shown) may be provided to block the frequency error correcting effect in the event of a drop in level so that recovery time of the circuit is shortened after such drop. A field effect transistor (T1) is connected in parallel with capacitor C hence if the level drops below a determined value (T1) is rendered conductive by a monitoring device (PU, not shown) hence shunting capacitor C so that the amplifier V2 is rendered inoperative. On restoration of signal level (T1) is rendered non-conductive. If this control stage is not present, charging and discharging of capacitor C requires a period of a few seconds.

Patent GB-668466-A (GB)
Title: Propylene polymerization process and product
IPC: C08F10/00
Filed: 1948-10-08
Abstract: <PICT:0668466/IV (a)/1> Propylene polymers having small changes in viscosity with changes in temperature are produced by admixing propylene, aluminium bromide dissolved in a non - polymerizing hydrocarbon solvent, and a catalyst promoter consisting of hydrogen bromide, bromo-alkanes containing at least 3 carbon atoms, e.g. isopropyl and isoamyl bromides, or compounds which react under the conditions of the reaction to produce hydrogen bromide, e.g. water, in proportions such that during the reaction the mol. ratio of catalyst promoter to aluminium bromide is between 0.2 and 5 and the rate of addition of propylene is not greater than 2 mols. per mol. of aluminium bromide per minute.  The aluminium bromide concentration is preferably between 0.01 and 1.5 mol. per cent based on the non-polymerizable hydrocarbon.  Suitable hydrocarbon solvents are ethane, propane, and n-butane which may also be used as diluents for the propylene.  Ethylene may also be used as diluent in non-polymerizing conditions.  The reactants are preferably brought to the desired temperature, generally from - 80 DEG  to 30 DEG  C., before being charged to the reaction vessel.  External heat exchangers or internal refrigerants, e.g. carbon dioxide, may be used to maintain the required temperature.  After polymerization, the catalyst may be recovered for re-use by extracting with a hydrocarbon immiscible liquid, e.g. iso-octane or turpentine, or by heating, e.g. to 80 DEG  C., when it forms an insoluble tar with the solvent. Where recovery is not required, the aluminium bromide may be removed by addition of water, alkali or alcohol. The process can be effected as a batch or a continuous operation. In the latter, referring to the drawing, propylene and solvent-diluent are fed through lines 5 and 10 and heat-exchangers 9 and 14 to the reaction vessel 7.  Solid aluminium bromide is melted in vessel 15 and dissolved in a portion of the solvent in mixer 21 before passing to the reaction vessel, and the promoter is fed through line 27.  The ratios of monomer, catalyst and promoter are controlled by valves 32, 34 and 35.  The polymeric products are withdrawn from vessel 7 to vessel 40 where they are heated to precipitate the aluminium bromide.  The tar is separated in vessel 44 and may be sent on for recovery of the catalyst.  The polymeric products are pumped through clay chambers 48 and 49 for inactivation of remaining catalyst and on to the fractionating column 55 where the solvent-diluent and most of the promoter are removed overhead through line 56 and recycled.  The bottoms are then passed to column 61 operating at a higher temperature and lower pressure than column 55 and light polymer products and remaining promoter are removed overhead.  The polymers, which have viscosities at 210 DEG F. of between 30 and 10,000 Saybolt Universal Seconds, are used as lubricating oils or oil additives.
