Abstract: 551,961. Isomerizing hydrocarbons. STANDARD OIL DEVELOPMENT CO. Nov. 28, 1941, Nos. 15331 and 15332. Convention dates, Nov. 22, 1940. [Class 2 (iii)] Straight chain hydrocarbons such as butane to octane, field butanes, straight run naphthas, or simple branched chain hydrocarbons containing at least 4 carbon atoms per molecule are isomerized to branched chain paraffins by contact with a halosulphonic acid with or without a boron trihalide promoter at 40-350‹F. Free hydrogen, methane, ethane, and propane may also be present. The catalyst may be the chlor-, fluor- or brom-sulphonic acid and may be replaced by the required amount of sulphur trioxide and hydrogen halide for its formation. Examples are given of the isomerization of butane, pentane and heptane using fluorsulphonic acid which may be regenerated by heating with sulphur or carbon to liberate hydrogen fluoride which is reunited with sulphur trioxide.

Abstract: 1413242 Ultrasonic probes BRITISH STEEL CORP 29 March 1974 [30 March 1973] 15401/73 Heading H4J Ultrasonic testing apparatus, for rotation around a steel tube 2 (Fig. 1) or other article to be tested, includes an ultrasonic pulse generating probe 9 having a transmitting face 10 located in a recess 21 extending radially of the axis of rotation. Coupling liquid is supplied to the recess 21 and at least part of such liquid is directed transversely across the probe face 10. Part of the coupling liquid is exhausted from the recess 21 adjacent the face 10, whereby to flush dirt particles from the recess 21. Several probes 9 may be provided and at least some may be spaced circumferntially around the axis of rotation. A pad 1 rides over steel tube 2 and rotates in the direction of arrow 3 as tube 2 moves axially. An inclined guide 4 assists the probe assembly in riding over protrusions on the tube 2. Pad 1 is carried by a block 5 which carries two radially arranged tubes 6, 7. Block 5 has an inlet pipe 13 for water, part of which passes via a port 14 directly into recess 21, whilst part flows through a channel 15 in tube 6 and into the recess 21 at the outer end of tube 6. As water exits from channel 15 it impinges upon and flows across surface 10 and passes out of the recess 21 via four ports 16 in an annular chamber 17 formed in a surrounding collar 18 clamped by a screw 19. Water from chamber 17 exhausts through a bore 20. In use, centrifugal force ensures rapid filling of recess 21 with water, the water establishing acoustic coupling between the tube 2 and the probe 9. Small dirt or scale particles from the tube 2 exhaust through bore 20, whilst larger particles remain in chamber 17 until collar 18 is cleaned. The flow capacity of the outlet 20 is considerably less than the inlet 13. Excess water leaks from the radially inner end of the recess 21 around the tube 2.

Filed: 1936-06-04
Abstract: 476,237. Cathode-ray tubes. WILLIAMS, W. E. June 4, 1936, No. 15631. [Class 39 (i)] In an electron-discharge device an electron image of an optical image incident on a photoelectric cathode is focused in a plane, one scanning line only of the electron image is incident on a secondary-emitting electrode at any time and the secondary electrons produced fall on a storage electrode. In one form, the electron image from a photo-electric cathode 2 is focused on a screen 3 which has a slit 4 allowing one scanning line to fall on the secondary-emitting electrode 5, from which secondary electrons fall on a storage electrode 6, which is scanned by a beam from cathode 7. In a modification, the secondaryemitting electrode has the width of a scanning line and is placed in an aperture in the screen 3, the slow secondary electrons being focused on a storage electrode placed to one side, to avoid fast primary electrons which pass straight through the aperture in screen 3. The screen is preferably of high permeability magnetic material to prevent disturbance of the secondary electrons by the field deflecting the primary electron image across the slit 4. An equipotential grid may be mounted near the electrode 6 and between it and the cathode 7. Specification 461,197 is referred to.

Abstract: 476,253. Embossing relief-pictures. HERTZ, B. S., and POSNACK, E. R. June 5, 1936, No. 15826. [Class 11] [Also in Group XVI] A relief-picture is made from a stretchable picture-bearing sheet by assembling several layers of sheet material, cutting out a silhouette aperture and dies from the entire assembly, mounting one of the layers on the rear of the picture sheet and interposing certain of the other layers between the face of the picture sheet and a flat surface to form a spacing wall, all the silhouette apertures coinciding with the picture, placing the dies against the corresponding areas to be depressed, and applying pressure upon the rear of the picture sheet through the aperture to force the sheet within the spacing wall towards the flat surface until the dies are brought into contact therewith to produce depressions in the corresponding areas. The picture 24 is traced on translucent paper, and thence on to an assembly of one sheet of cardboard between two thicker sheets of composition board. From this assembly a silhouette opening corresponding to the outline of the picture is cut by a jig-saw, and the portions corresponding to the areas 25-30, Fig. 1, which are to be raised or depressed, are separated. The original picture, which may be soaked in glycerine solution, is glued to a backing of craft paper 38, Fig. 19, which is coated with an extensible material such as glue. The cardboard silhouette 41 is mounted on the back of the mounted picture and the composition board silhouettes 39, 40 are superimposed thereon in register to form a retaining wall within which is placed a yieldable and preferably heated plastic mass 56, preferably comprising whiting, ground hide glue, rosin, and linseed oil. The portions 39, 40 are then transferred to the face of the picture. According to the depth of depression required, one or more of the composition board layers 45, 47, 48, 51 corresponding to the portions 25, 26, 27 which are to be depressed are placed in register on the face of the picture. To secure the correct modelling certain of these layers are shaved off at the edge as at 54, 54a. The assembly is placed between the jaws of a press and compressed until the layer-portions 48, 51 come into contact with the upper jaw of the press and act as dies to model the picture 24. The assembly is then removed from the press and may be modelled in detail by hand and is finally mounted on a backing. For quantity production a plaster cast and thence a duplicate metal mould are made from the modelled picture, and the mould is used to model similarly mounted pictures, arranged between silhouette cardboard mounts and backed with a plastic filler.
