Patent GB-742769-A (GB)
Title: Improved process for reforming gasolines
IPC: C10G59/04
Filed: 1953-11-02
Abstract: A process for obtaining gasolines having an octane number in the range of 90-100 comprises reforming a straight-run gasoline with an acidic platinum catalyst under hydrogen pressure and under conditions of elevated temperature and pressure which allow continuous operation with no appreciable decline in catalytic activity while raising the octane number to between 80 and 90, and then subjecting the partially reformed gasoline to a purely thermal reforming treatment to increase its octane number to a value within the range of 90-100.  The acidic support for the platinum catalyst may be a silica-alumina composite, or a non-acidic carrier which is rendered acidic by inclusion of an acidic substance such as boric oxide, phosphoric acid or a halogen. Such supports may be those described in Specifications 657,565, 686,641 and U.S.A. Specification 2,478,916.  In a typical example (No. II) a straight-run naphtha was reformed with a commercial platforming catalyst to produce an aviation base of boiling point 110-191 DEG  C. and octane number of 88 which was then thermally reformed at 501 DEG  C. and at a pressure of 750 pounds per square inch to give a product having an octane number of 90. Thermal reforming under more severe conditions gives a product with an octane number of 98.

Title: Improvements in or relating to television pick-up tubes or the like
IPC: H01J31/32
Filed: 1948-11-22
Abstract: 655,290. Cathode-ray tubes. CINEMATELEVISION, Ltd., and FREEMAN, G. S. P. Nov. 22, 1948, No. 30262. [Class 39 (i)] A method of deriving picture signals in a television pick-up tube comprises scanning a double-sided target with an electron beam having a velocity equivalent to between 10 and 250 volts, the secondary electrons released by the scanning beam being prevented from returning to the target solely by an axial magnetic field and the electric field between the target and at least two cylindrical electrodes coaxial with the target. In the Figure, the electrons from photo-cathode 1 penetrate the metal film 2 and cause secondary emission from the aluminium oxide layer 4 which charges the glass target 5 negatively. Secondary electrons caused by the scanning beam are accelerated away from the target by electrodes 11 and 12 and are focused by the axial magnetic field caused by the coil 9 so that they fall on the electron multiplier 7. A decelerating system 8 may be provided which by means of velocity sorting may be used to prevent electrons corresponding to black picture elements from reaching the multiplier. The scanning beam should restore the target to a potential near that of the final anode and preferably has such a velocity that the secondary emission ratio of the target is about 2 : 1. This may be achieved by using a beam velocity equivalent to between 20 and 50 volts. Instead of deriving signals from the returning beam the tube can be operated by drawing the signals capacitatively from the metal film 3. Specification 655,291 is referred to.

Filed: 1926-11-30
Abstract: 262,156. Moyer, C. L. Nov. 30, 1925, [Convention date]. Heating by electricity.-In a stand for an electric iron provided with a switch controlled by a heat sensitive member 57, the switch mechanism is also affected by the position of the iron relative to the stand. At starting, placing the iron on the stand closes the switch for subsequent release by the heat sensitive means. Removal of the iron then closes the switch for subsequent release by cooling of the heat sensitive means. The stand is provided with a receptacle 22<1> containing sockets for engaging the supply plug 26 and terminals connected to leads 30, 32, connected to the heat-. ing element in the iron. The heating circuit is closed when the member 39 is depressed against the spring 40 to bring the member 35 into engagement with contacts 31. The member 39 carries members 47 adapted to be engaged by spring connected members 21, 22 when the iron is on or off the stand respectively. The members 21, 22 are pivoted in arms 10 mounted on a pivot 9 and adapted to be depressed by the iron against springs 13. The heat sensitive member 57 is coupled at 61 to members 60 mounted on the pivot 9. Expansion and contraction of the member 57 oscillates the members 60 to move one of the members 21, 22 out of engagement with the members 47 to release the switch. The top of the stand is made like a shallow pan so that the iron may be placed crosswise thereon without depressing the arms 10 sufficiently to affect the switch.

Filed: 1919-12-09
Abstract: 136,554. Soc. Generale des Compteurs de Voitures (Taximetres). Oct. 7, 1918, [Convention date]. Driving machines.-In a drilling or like machine, the feed-driving mechanism, such as a worm-wheel 12, is coupled to the feed-sleeve 4 through wedges 10, which are pressed out of their operative position when the hand-feed shaft 1 is operated, by means such as the stops 17 on the sleeve 14 attached to the shaft 1. Further movement of these stops brings them into engagement with the sides of the recesses 9 in the sleeve 4, which is then actuated by the hand-gear. When the hand-gear is released, the wedges 10 are moved by springs 11 into engagement with the eccentric surfaces of the portion 8 of the sleeve 4, and the concentric surface of the wheel 12, which thus may drive the sleeve 4 in either direction. The shaft 1 may be turned either by a handle 2 or by a handle 19 mounted to rotate freely in a casing pivoted on the shaft 1, and geared by bevel-wheels 16, 20 to the sleeve 14. The stops 17 may be replaced by a pin fixed in a transverse hole in the shaft 1, the projecting ends of which engage the wedges.
