Title: Improvements in the cracking, and/or hydrogenation of liquid hydrocarbons
IPC: C10G9/36
Filed: 1924-02-01
Abstract: 233,395. Wallace, G. W. Feb. 1, 1924. Hydrocarbons, cracking.- In treating hydrocarbons such as shale or petroleum oils, naphthalene oils, anthracene oils, &c. for cracking and hydrogenation, the oils in a finely divided form are brought into contact with or proximity to a flame obtained by burning a liquid or gaseous fuel with just sufficient air for complete combustion. Steam and gases or vapours which effect hydrogenation may be passed in with the hydrocarbon and may be used to atomize it. Air and combustible gas are passed in regulated quantities through inlet 11, 10 and combustion is effected in a chamber 13 containing refractory material such as carborundum. The hydrocarbon is introduced through a pipe 12 and nozzle 14 into the downwardly directed products of combustion which pass through a chamber 1 to an outlet 16 and through a dephlegmator 18 to a condenser 20 and an oil scrubber 27. The chamber 1 may be lined with or filled with briquettes, carbon, pumice, &c., which may be coated or impregnated with catalytic materials. Powdered catalytic materials such as pumice impregnated with a nickel catalyst may be mixed with the hydrocarbons prior to treatment. The process may be carried out under increased or reduced pressure.

Abstract: 806,789. Semi-conductor devices. GENERAL ELECTRIC CO, Ltd. April 25, 1957 [Jan. 27, 1956], No. 2744/56. Class 37. [Also in Group XL (a)] A crystalline body of cadmium sulphide is activated, to reduce its resistivity and to increase its photosensitivity, by the application to the body of an electric field sufficient to cause dielectric breakdown, followed by the passage through the body of a current at a density of not less than 0.1 amp./sq. cm. Preferably the body is heated from an external source during the process. As described, in the manufacture of a photo-conductive cell, a thin flat grown single crystal of cadmium sulphide is mounted on a ceramic support, and two lead wires sealed through the support make connection with graphite coatings disposed at opposite ends of the exposed face of the crystal which is disposed in an oven and, having been connected in series with a high resistance is heated to 400‹ C. and a voltage sufficient to cause dielectric breakdown is applied for five minutes, after which the crystal is allowed to cool. The crystal and its support are then enclosed in transparent synthetic resin. A crystal activated according to the invention may also be used in conjunction with an electroluminescent element, e.g. zinc sulphide activated by copper, in an electro-optical trigger device; further possible applications are large area rectifiers and photovoltaic cells.

Abstract: 371,893. Projection screens. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A., BULL, R. A., 5, Duppas Hill Road, Croydon, SMALL, C. J. P., 8, Church Row, Hampstead, SIMPSON, G. A. G., 20, Milton Mansions, Queen's Club Gardens, West Kensington, and MAYER, C. G., 1SA, Sussex Place, Old. Brompton Road, all in London. Jan. 29, 1931, Nos. 2956 and 22493. [Class 97 (i).] Projection screens of translucent material comprising small contiguous lenses are so constructed that when a uniform pencil of parallel light falls upon a lens, the light transmitted in any direction by it is proportional to the cosine of the angle between such direction and the optical axis of the lens; each lens may cause a ray impinging upon it to be bent through an angle having a sine proportional to the distance of the ray from the optical axis of the lens. Each lens may have its faces respectively plane and curved, the curvature being given by the formula x = K sin (sin -1 u sin alpha - alpha) where alpha is the angle between the plane of the screen and a plane tangential to the surface at a point p, x is the distance of the point p from the optical axis of the lens, Á is the refractive index, and K is a constant ; alternatively it may have two cylindrical surfaces having axes at right-angles. The lenses may transmit no light perpendicular to the screen, and the surfaces between the lenses or the apexes of the lenses may be ground or otherwise treated. The lenses may be polygonal in outline, and may be rectangular as shown in Fig. 1 (Comp.) ; they may be prismatic in form near the edges of the screen either by displacing their optical axes 34 .. 37 from the normals 26 .. 29 through their centres of area, as shown in Fig. 1 (Prov.), or by forming prismatic steps 40 .. 43 on the back of the screen as shown in Fig. 2 (Prov.). The screen may be formed from a sheet of cellulose acetate by means of press tools &c. According to the first Provisional Specification it may also be formed by embossing, moulding, engraving, milling, or rolling, and a moulding die may comprise spheroidal collars turned on a number of lengths of wire. Specification 24917/11, [Class 97 (i), Optical systems &c.], is referred to.

The pivot 13 is arranged to allow universal movement, the end of the stay having curved upper and lower faces fitting between the lugs 14, Fig. 7, of a bracket which, in the form shown, carries the pivot pin 13, the hole in the end of the stay-rod being elongated to allow the stay to rock on the pin. The curved faces of the stay may be part-spherical and the hole enlarged to allow rocking in all directions ; in a modification, the pin is carried by the stay and engages holes in the lugs 14 with sufficient play to allow rocking.

Abstract: 571,491. Boring-heads. BALL, E. D., and TAYLOR, F. G. Feb. 17, 1944, No. 2997. [Class 83 (iii)] A cutter-bar of the type that is supported at one end and carries a tool near its other end, has the tool mounted for diameter adjustment by a sliding thrust rod, within an axial bore, having an end bearing against the cutter, whilst the other is connected to a screwed member engaging with a rivet secured on the bar. The cutter is opposed by a steady pad. The bar 1 is threaded at 13 for a nut 14 that is also threaded to engage a screwed sleeve 17 sliding on the bar and carrying a cross-pin 11 passing through a slot 2 in the bar and connected to the thrust rod 10. The two threads of the nut differ in pitch enabling a fine adjustment to be made, for example, one revolution of the nut may produce 0.005" radial adjustment of the cutter and the bevel edge of the nut is graduated to read with an index mark on the bar to 0.0001" or less. The cutter 4 is mounted in an inclined slot and is opposed by a pad 5, the cutting edge 8 being in advance of the pad which is adjusted by a set-screw 9. A locking-wedge 6 located between the pad and cutter is formed as a half-nut to engage a grub-screw 7 located in a semicircular groove in the pad. In a modification permitting interchange of the cutter carrying end of the bar according to the diameter required, this end of the bar is held in a collet 25, Fig. 5, held in the other part of the bar by a screw cap 24. The thrust rod 10 has a connection 29 with a cross-bar 11 engaging the adjusting-nut 14. The thrust rod is shown as flatted in Fig. 2 to pass coolant and centrally perforated at 18, Fig. 5, for the same purpose.

Abstract: 1537485 Phase splitter circuits RCA CORPORATION 27 Jan 1976 [24 Feb 1975] 03063/76 Divided out of 1537484 Heading H3T A phase splitter circuit, e.g. for a Class B or AB push-pull amplifier, comprises four transistors connected as two emitter coupled pairs 1, 2 and 1<SP>1</SP>, 2<SP>1</SP> with current sources 3, 3<SP>1</SP> connected to the respective coupled emitters of each pair, an input terminal, for receiving signal current from a source 7<SP>1</SP>, feeding the bases of 1 and 1<SP>1</SP> in parallel, loads 6, 5<SP>1</SP> connected to the collectors of 2 and 1<SP>1</SP> respectively, and base biasing means such as 8a, 8b, such as to render 2 and 1<SP>1</SP> substantially less conductive than 1 and 2<SP>1</SP> under nosignal conditions; each transistor may be replaced by a current mirror amplifier. If the current sources 3, 3<SP>1</SP> supply currents IT, and 2 and 1<SP>1</SP> are biased off, the emitter currents of 1 and 2<SP>1</SP> are equal to IT under no-signal conditions, and the input current which flows entirely to the base of 1 is IT/(#+1), where # is the common-emitter current gain. If an applied signal has a negative excursion so that the input current is reduced by an amount i I#N , transistor 1<SP>1</SP> remains off but transistor 2 is turned on with a collector current #i#IN. Conversely, with a positive-going signal i#IN transistor 2 remains off but transistor 1<SP>1</SP> is turned on with a collector current Zi#IN. The effect of temperature on the circuit is compensated for by providing base biasing potentials which are proportional to the absolute temperature T, all the transistors being in close proximity, and hence having the same temperature.
