Title: Process for isomerizing mono-olefinic hydrocarbons
IPC: C07C5/25
Filed: 1946-06-26
Abstract: Mono-olefins are isomerized by contact with an aqueous solution of hydrogen chloride, hydrogen bromide or a hydrolysable salt thereof having a pH of between about 3 and 7.  Specified salts are chlorides and bromides of ammonium, iron, nickel, magnesium and manganese. Temperatures are generally 25-400 DEG  C.  Temperatures and pressures above the critical are effective.  The hydrocarbon vapours may be contacted with the catalyst or liquefied hydrocarbons passed with catalyst through tubular elements or into a mixer.  A C4 fraction from the cracking of oils may be fractionated to separate butene-2, and the residue isomerized to convert butene-1 to butene-2 without reaction of isobutene which can then be isolated.  Pentene-1 and 2,3-dimethyl butene-1 may similarly be isomerized.  In examples, aqueous ammonium chloride is used as the catalyst.  Specification 576,480 is referred to.

Title: Device for electromagnetically maintaining the oscillating movement of the regulating member of a timepiece
IPC: G04C3/06
Filed: 1960-06-03
Abstract: 906,775. Clocks and watches. SOC. SUISSE POUR L'INDUSTRIE HORLOGERE S.A. June 3, 1960 [June 10, 1959], No. 19773/60. Class 139. A timepiece regulating member, e.g. a balance 1, Fig. 1, is maintained in oscillation by the interaction between a coil 10 and a magnetic flux generator 7, 8, 9 and the coil is connected in series in an electric circuit comprising a battery 11 and a bi-stable element having a negative resistance for certain values of the battery voltage. The circuit is so designed that the subtraction of the voltage induced in the coil as a result of the variations in the flux passing therethrough from the battery voltage, produces the change-over of said element from its stable state determined by its maximum resistance to its stable state determined by its minimum resistance while the addition of the voltage induced in the coil to the battery voltage produces the change-over of the element from its stable state determined by its minimum resistance to its stable state determined by its maximum resistance. The bi-stable element comprises a transistor T which has a groove 13 in its base surrounding the emitter E. The base contact b1 is negatively biased by a battery 12 and the second base contact b2 situated between the groove 13 and the emitter E is positively biased by a battery 14 through a variable resistance 15 so that the value of the potential difference between the collector and the base at which the collector junction space charge zone reaches the groove 13 can be varied. The transistor has the Vc-Ic characteristic shown by the line ODF in Fig. 3, so that a positive voltage pulse induced in the coil causes a change-over of the bi-stable element to produce collector current pulses. In another example an ordinary transistor is used and its base is biased through a fieldistor controlled by the collector voltage. Two series-connected coils may be used. Specifications 900,461 and 905,945 are referred to.

[Class 83 (ii)] [Also in Groups XXXIV and XXXVI] An anti-friction bearing comprises three or more mutually bonded strata of different materials arranged in order of increasing hardness away from the bearing surface. Fig. 6 shows a bearing block for use in the big end of a connecting rod. consisting of a backing- member 20 of a strong durable material such as steel coated interiorly with a softer material 28 such as silver which forms a base for a highly flowable malleable material 36 having good oilwetting properties such as lead. The surface of the silver layer 28 may be roughened by sand blasting and the lead applied by electro plating. The lead surface is then smoothed down to the proper thickness by a rolling operation. The lead surface may be fortified by electro plating with indium, thallium or gallium. This electroplating may be effected in the case of cylindrical plain bearings by means of a fixture protecting the ends of the bearing and carrying the anode. The interior of the bearing is filled with the plating solution and the current passed between the anode and the backing shell or bearing-retaining member. The bearing may be heated in an oil bath for about two hours to a temperaure about 340‹F. between the melting points of indium and lead to cause the indium to impregnate the lead and produce a corrosion and erosion-resisting alloy.
