Title: Process for producing low pour point transformer oils from waxy crudes
Inventor: SPROULE LORNE WILLIAM
IPC: C10N40/16
Filed: 1970-01-27
Abstract: 1,274,811. Electrical insulating oils. ESSO RESEARCH & ENG. CO. 27 Jan., 1970 [28 Jan., 1969], No. 3825/70. Headings C5E and C5F. An electrical insulating oil is made by solvent extracting a waxy paraffinic vacuum gas oil fraction having a 5-95% boiling range of 550- 750‹ F., dewaxing the extracted fraction to a pour point of + 20‹ to - 25‹ F. and separating the dewaxed oil into at least three fractions such that the insulating oil is recovered as a heart cut having a 5-95% boiling range of 580- 720‹ F. An oil 2 is extracted at 12 by a countercurrent of phenol or furfural at 120-250‹ F. and up to 250 p.s.i.g. to remove aromatics and polar components. The raffinate 5 is diluted with liquid propane, methyl ethyl ketone and/or methyl isobutyl ketone and dewaxed by cooling to between +20‹ and -40‹F. and filtering. The diluent is flashed from the dewaxed oil which is then hydrofined at 16 with a catalyst of oxides or sulphides of Co and Mo, Ni and Mo or Ni and W at 350-650‹ F. and a hydrogen pressure of 300-900 p.s.i.g. The hydrofined oil is fractionally distilled to provide an overhead fraction 10(a), an insulating oil fraction 10(b) and a bottom fraction 10(c). The fraction 10(c) can be used as such as a lubricating oil or a heavier fraction 10(d) can first be removed therefrom. A transformer oil comprises the insulating oil stream 10(b) and 0À06% of a 2,6-ditertiary butyl paracresol oxidation inhibitor and 0À07% of a wax-alkylated naphthalene pour-point depressant.

Abstract: 147,966. Williamson, R. L. Feb. 18, 1919. Centrifugal governors. - In hydraulic power-transmission apparatus of the type in which pumps carried by the driving- shaft are operated by means carried by the driven shaft to pump liquid round a more or less restricted circuit, means are provided for holding the pumps out of action, should the speed of the driving shaft fall below a predetermined minimum. The driving shaft 1 carries pumps 14, the pistons 15 of which are connected to pivoted segments 18 bearing on rollers 20 on the driven shaft. On rotation of the driving shafts, the pistons 15 reciprocate freely, or the rollers 20 are carried round according as a throttle is open or closed.

Abstract: 661,215. Handling transferable load-containers. HODGES RESEARCH & DEVELOPMENT CO. Feb. 18, 1949. [March 29, 1948] No. 4470/49. Class 78(iv). In means for transferring a wheeled freight-container from one vehicle or platform to another, articulated bridging elements are slidably mounted in wheelguides recessed in the surface of one vehicle or platform. In Fig. 2 each of the bridging elements comprises a central section 39 sliding in a guide 20 on a railway car platform 11 and articulated at each end to sections 40, 41, 42 by means of vertical pivots 48, 50 and a horizontal pivot 49. The whole of the bridging means may be housed in the guide 20 and may be withdrawn so that, as shown in Fig. 2a, the section 42 may rest by a tongue 51 on the base of a channel 54 on the platform 12 of a road vehicle trailer and be secured in position by a pin 60 passing through holes in lugs 58 forming adjustable ends for the channel 54 and through a vertical slot (not shown) in the section 42. The container 10 (Fig. 1) to be moved is equipped with hydraulic jacks 14 which may be removable and which each carry a wheel 18 formed with a central groove 19 (Fig. 3). When the jacks 14 are extended with the container 10 on the railcar, the flanges 28, 29 of each wheel 18 engage tracks 26, 27 on members 24, 25 secured with the aid of spacers 30, 31 in the guide 20 so that no pressure is exerted on the bridging element. The tracks 26, 27 are formed at their ends with ramps 32, 33 (Fig. 2) down which the flanges 28, 29 of the wheels 18 roll until the groove 19 engages the upper surface of the bridging element means. To facilitate passage of the wheels 18 the upper surface of the bridging means is reduced in width at 38a, 38b adjacent the vertical pivots 48, 50. The upper surface of the tongue 51 is formed as a ramp 52 to lower the wheels 18 until the flanges 28, 29 engage the base of the channel 54. The central section 39 of each bridging element is guided in the guide 20 by shoes 43, 44 (Figs. 2 and 3) pivoted at 45 to the section 39 and adapted to engage the undersides of the members 24, 25. The means for moving the containers between the vehicles comprises winches 63, 64 mounted on a shaft 65 on the railcar and controlled in their rotation together in either direction by a. lever 66. Cables 80, 82 are oppositely wound on the winches 63, 64 respectively and pass under rollers 73 in brackets 67, 68 and over pulleys 71 or 72 in frames 69, 70, pivoted in the brackets 67, 68, for connection at 81, 83 respectively to the container 10. The cable 80 passes between the pulley 71 and connection 81 by way of a pulley 75 in a bracket 77 pivoted at 78 to the trailer 12 and held against lateral movement in the position shown by horns 79.

Title: Improvements in or relating to wireless direction finders

Abstract: 784,825. Radio direction-finding. PHILIPS ELECTRICAL INDUSTRIES, Ltd. (Naamlooze Vennootschap Philip's Gloeilampenfabriken). Feb. 14, 1956, No. 4590/56. Class 40 (7). A radio direction finder for determining the direction of reception of incoming signals relative to the plane of symmetry of the overlapping patterns of two differently directed directional aerials is so arranged that relative variation of phase shift and gain between two amplifier channels associated with the aerial system does not affect the alignment indication. The aerial system may comprise a parabolic cheese reflector 1 having two off-centred coupling feed guides 2 and 3. These are connected by waveguides 4 and 5 to a " magic T " whose outputs are the sum and difference of the feed guide signals. The sum and difference outputs are respectively fed to crystal mixer stages 8 and 9, each fed from local oscillator 10 and the resulting I.F. signals passed to the amplifier channels 11 and 12. The amplified I.F. signals are fed to switching device 14 controlled by square wave generator 13 so that the output to amplifier 15 is alternately the sum and difference of the inputs; i.e. is alternately proportional to the two aerial feed signals. The segmental signals are rectified at 16 and need to give vertical deflections 24 and 25 on the trace of indicating cathode-ray tube 17. The horizontal scan of this is provided by sawtooth generator 22 synchronized with generator 13. The apparatus is suitable for operation with a pulsed input signal and the indications 24 and 25 represent the display with such an input. A synchronizing connection 23 from the sum channel is necessary to synchronize the switching and display arrangements with the recurrence frequency of the incoming pulses. As no signal passes through the channel 12 when the aerial inputs are equal any difference in the two channels does not affect the alignment indication. As, however, differences in the two channels do affect the indicating sensitivity, an adjustable phase shifter 26 is included in the connection between the local oscillator and the mixer 8 so that correction can be made for relative phase shift between the two channels. Other means for providing the sum and difference of the aerial signals may be substituted for the " magic T " and a suitable switching arrangement (Fig. 2, not shown) is described for alternately providing the sum and difference of the amplifier channel outputs.
