Title: Improvements in cellular bodies of asphalt and a method of producing the same
IPC: C10C3/14
Filed: 1927-06-21
Abstract: 279,360. Robertson Co., H. H., (Assignees of Young, J. H.). Nov. 8, 1926, [Convention date]. Drawings to Specification. Pitch. - Cellular bodies of asphalt, bitumen, &c., are obtained by saturating the bituminous substance under pressure with a gas which is soluble in it, and then releasing the pressure causing the gas to form bubbles, which however, are not permitted to migrate from their points! of origin. The bituminous material is preferably heated and agitated to facilitate solution of the gas, which may for example be natural gas, but it is cooled to a state of plasticity before the pressure is released. The release of pressure may be caused by extruding the material through orifices which give it the desired form.

Title: Process for distilling or converting hydrocarbon oils with powdered solid materials
IPC: C10G11/18
Filed: 1942-11-24
Abstract: 569,187. Distilling and cracking oils. UNIVERSAL OIL PRODUCTS CO. Nov. 24, 1942, No. 16643. Convention date, Oct. 27, 1941. [Class 32] In processes for the distillation or conversion of hydrocarbon oils in the presence of fine divided contact or catalytic material, of the kind in which the suspension of catalyst and oil is maintained in a fluidized dense phase in the lower region and in a dilute phase of substantially lower density in the upper region of the conversion chamber, the oil is introduced into the conversion chamber at least m part in the liquid phase and is therein converted into the vapour phase by introducing heat carrying gas into the dense phase at sufficiently elevated temperature to vaporize the oil. The heat carrying gas may comprise hydrocarbon gases obtained in the process. Charging stock fed through line 1 and preheated in coil 6 is discharged through lines 8, 69, 71 into a reactor 10 supplied with regenerated catalyst through line 36 at a rate to maintain a density of 0.32 kilograms per litre in the lower part of the reactor. The distilled or cracked products pass through separators 13 to a recovery plant comprising fractionating, stabilizing and polymerizing towers 41, 47, 55, 58, from which gasoline and higher boiling fractions are recovered while the hydrocarbon gases are separated and fed through line 63 and heater 65 and thence discharged through line 67 to mix with recycled catalyst in line 36 and constitute the heated gases for vaporizing the oils in reactor 10. The catalyst separated in separators 13 is collected in receiver 14 and passes thence through line 15, where it is mixed with inert gases from line 18 and oxygen containing gases (air) heated in coil 26 and fed to regenerator 20. The regenerated catalyst separated in separators 32 and collected in receiver 35 is recycled through line 36. In Fig. 2, the preheated oil fed through line 74 entrains catalyst fed through line 100 from the regenerator 93 on its path to the reactor 76, the vaporizing gases being admitted through lines 78, 79, 80, 83, while the contaminated catalyst is withdrawn through line 89 and, admixed with regenerating gases fed through line 91, is discharged into the bottom reactor 93.

Title: Improvements in mechanically driven selector switches
IPC: H01H67/06
Filed: 1950-07-05
Abstract: 676,488. Electric selectors. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 5, 1950 [July 7, 1949], No. 16784/50. Class 40 (iv). [Also in Group XXIV] To provide rapid stopping of a wiper carriage coupled to a rotary driving-shaft, the coupling mechanism is disengaged by overthrow after the carriage has been arrested. In the first embodiment, Figs. 1-3, energization of magnet 40 withdraws pawls 37, 38 from the associated wheels 3, 19. Pawl 22 drops under spring action to couple constantly driven wheel 20 to auxiliary wheel 19 which then rotates wheel 3 and wiper carriage 5 through spring 32. The test wipers 18 wipe over the contacts of bank 17 until the desired voltage is found, when magnet 40 deenergizes and pawls 37, 38 are urged by springs 45, 46 towards wheels 3, 19. The stop-pawl 37 locks ratchet-wheel 3 immediately and stops the wiper carriage, but pawl 38 is less positive and the wheel 19 is carried along momentarily by the driving-wheel 20, so that projections 33 push the plates 9 of the carriage 5 against the action of springs 15 to engage wipers 12 with the selected contacts. A projection 30 on a pawl 28 pivoted to wheel 19 engages with the right-hand side of an aperture 31 in wheel 3 so that further movement of wheel 19 pushes coupling pawl 22 against the inclined face of pawl 28, whereby pawl 22 is lifted to disengage the driving-wheel 20. A slight return movement of wheel 19 pushes pawl 38 backwards to lock the toggle 42, 43. When the connection is to be broken down, magnet 40 is energized again to break the toggle 42, 43 and release pawl 38. Wheel 19 then moves back under the action of springs 15, wipers 12 disengage the selected contacts and projection 30 engages the left-hand side of aperture 31 to release pawl 22 which couples wheels 19, 20 again. Pawl 38 also engages pin 48 to retract stop pawl 37 and the wiper carriage is driven again. Modification. Energization of magnet 86, Figs. 4, 5, withdraws pawls 80, 81 to allow auxiliary member 63 and ratchet-wheel 64 to rotate, ratchet-wheel 62 associated with driving- wheel 61 engaging coupling pawl 65 to drive auxiliary member 63, which drives ratchetwheel 64 through springs 69. Member 63 also drives disc 73 and wiper holder 71 through lugs 76 and 78. To stop the selector, magnet 86 is de-energized, stop-pawl 80 arresting ratchetwheel 64 and wiper holder 71 immediately, while auxiliary pawl 81 merely slows down auxiliary member 63 and lugs 76 pass beneath lugs 78 to lift the wiper holder 71 axially of shaft 60, so that wipers 74 engage the selected contacts 75. The part 66 of the coupling pawl 65 is carried against the edge 67 to rock the pawl 65 out of engagement with gear 62 to interrupt the drive. To interrupt the connection, magnet 86 is re-energized to withdraw pawls 80, 81, member 63 being released first and turning back under the action of springs 69, when all parts restore to normal position and the wiper holder rotates again.

Abstract: 623,022. Gauging apparatus. HUGHES & SON, Ltd., H., and SPROULE, D. O. June 3, 1946, No. 16847. [Class 106 (ii)] [Also in Groups XXXVIII and XL (c)] The output of an electric oscillator is passed through a modulator and then converted to mechanical vibrations which are transmitted through the material or space under test, detected, reconverted to electric oscillations which are passed through a demodulator, the output of which is applied to the transmitter modulator. As shown, Fig. 6, to determine the rate of flow of fluid 13, modulated sound vibrations are transmitted, along the line of flow, through 13, from the transmitter 12 and detected by 14; and simultaneously in the opposite direction, modulated vibrations pass between 121, 141. The differing modulation frequencies at 14, 14<SP>1</SP> are applied to the mixer 26 and the resultant beat frequency employed indicates rate of flow. In a second embodiment, not shown, modulated sound waves are passed between two members to be aligned; relative displacement of the members effects a change in the modulation frequency which is employed correctively to restore alignment. In a third embodiment, not shown, modulated sound waves are reflected from a liquid surface, a change in the level of which alters the length of the sound path and hence the modulation frequency, which may effect restoration of the liquid level.

Abstract: 723,648. Multi-stable state circuits. STANDARD TELEPHONES & CABLES, Ltd. July 17, 1951, No. 16933/51. Class 40 (6). A pulse frequency divider comprises two counting chains in which pairs of elements, one from each chain, are interconnected in dependence upon the divisor required. The Figure shows a divider in which the negative-going pulses to be divided are applied at the terminal " Input " to the common trigger electrode of a first gas-filled multi-gap sequence tube A of the type described in Specification 692,415 [Group XL (a)], the cathodes KA1-KA10 of which are cross-connected via coincidence gates MA1, MB10, MR1, MA10, MB1, MR10 to a second sequence tube B. Initially cathodes KA1 and KB1 are discharging and each input pulse applied causes the discharge of the first tube A to step forward one gap so that on the ninth pulse gap 10 fires and as cathode KB1 is discharging rectifiers MA10, MB1 are blocked and a positive pulse is applied via rectifier MR10 to the grid of amplifier valve VI. The resulting negative pulse at the anode of valve V1 is applied to the negative output terminal and to the trigger electrode of tube B, the discharge in which steps on to gap 2. The tenth input pulse causes gap 1 in tube A to re-fire and the discharge progresses along tube A until on the eighteenth pulse gap 9 fires and as gap 2 of tube B is firing a pulse is applied via rectifier MR9 (not shown) to valve V1 and then to the negative output terminal. The cycle thus continues with coincidence occurring one step earlier in each cycle so that division by nine is obtained. If division by eight is required then the coincidence is stepped forward two steps per cycle by interconnecting KA10, KB1; KA8, KB2; KA6, KB3, &c. Thus by interconnecting pairs of elements in a predetermined order, division by any divisor up to 19 may be obtained.
