Title: Improvements in and relating to the coating of articles by vaporisation of the coating materials
IPC: C23C14/32
Filed: 1937-06-09
Abstract: 481,842. Deposition of metal by electric discharge. BERGHAUS, B. June 9, 1937, No. 15972. Convention date, June 17, 1936. [Class 41] A body 19a, Fig. 1, is coated by metal particles proceeding from a body of molten metal in a crucible 7 connected to one pole of a high voltage source, preferably as cathode, in an exhausted or partially exhausted vessel, the particles being concentrated into a beam by the magnetic field of a coil' 14. The pressure in the vessel may be 20 mm. of mercury or as low as 0À001 mm. Accessory electromagnets 18a, 18b with fields at right-angles are provided to divert the beam over the article as required. The article 19a is mounted beneath an insulated metal plate 21 connected to the opposite pole of the circuit. The vessel is exhausted at 25, gas such as hydrogen, nitrogen, helium or neon being introduced as required at 24. The crucible is heated by a resistance 8. Material 7a for the emission of electrons is provided around the rim of the crucible, or the crucible may be made of such a material, for example, thorium oxide. The material to be vaporized may be in powder form. The parts 1, 2, 3 of the container are removably connected by ground surfaces 5, 6. Alternatively, the crucible may be heated by high-frequency induced currents or by an arc, or it may be formed in one with the container 2 and be heated externally by gas. In a modification, Fig. 5, the material is vaporized from the electrodes 36, 37 by an arc maintained by a local generator 39, the two electrodes together forming the cathode of the discharge generator 41 to produce a beam which is concentrated by the field coil 47. The article to be coated is mounted above the anode 44 in a separable part 34 of the container. The electrode 36 is secured to the armature 52 of a coil 53 for striking the arc. An additional source of electrons 63 connected to a source of voltage is provided. The current lead 50 may be a bimetallic strip which retracts the electrode 36 when heated.

Patent GB-717547-A (GB)
Title: Improvements in or relating to fluidized system
IPC: C10G35/14
Filed: 1952-06-25
Abstract: In a fluidized catalytic process for reforming hydrocarbons, a petroleum naphtha stock preheated to 970 DEG  to 1050 DEG  F. is introduced into a reactor having an average bed temperature of about 940 DEG  F. and at 250 p.s.i.g. which is maintained by pre-heated hydrogen-containing gases.  The primary reaction is stated to be the dehydrogenation of naphthene compounds and to a lesser extent the cyclization and dehydrogenation of aliphatic compounds of at least six carbon atoms to aromatic compounds. Further processes of fractionation and stabilization are described.ALSO:<PICT:0717547/III/1> <PICT:0717547/III/2> <PICT:0717547/III/3> A gaseous reactant is contacted with a fluidized mass of finely divided catalytic solids in a reaction zone (22) Fig. 1, and the contaminated solids withdrawn therefrom at a point below the entry of said gas, conveyed upwardly in a conduit (28) lying wholly within the reaction zone and a separate stripping zone (35), by means of a gas into said stripping zone, in which it is contacted as a fluidized mass with a stripping gas, passed to a regeneration zone (60) where at least part of the combustible contaminants is removed by burning in an oxygen-containing gas as a fluidized mass and thence returned to the reaction zone at a point below the entry of the reactant gas.  In the example, illustrated by Fig. 1, the reactant is petroleum naphtha and the hydrogen-containing conveying gas is passed into the reaction zone at a lower temperature than the temperature of the conveyed solids; a fluidizing gas is passed into the bed through the conduit 30 and the grid 25 at a higher temperature than the average temperature in the reaction zone; the regeneration zone is cooled by means of water in vertical conduits 87.  Further operations are described and illustrated including fractionation and stabilization.  The apparatus claimed includes a reaction vessel, a stripping vessel superimposed thereupon and sealed therefrom, a vertical conduit within the reaction vessel and extending into the inside of the stripping vessel and means whereby finely divided solids are conveyed upwardly in the conduit by the use of a gas.  The well 27 for withdrawal of contaminated catalyst should be level with or slightly above the grid, and the oilfeed entrance always lies below the entrance for regenerated catalyst and above the point at which contaminated catalyst is withdrawn.  Embodiments in which the stripping vessel lies partly within the reaction vessel as shown in Fig. 2 are claimed.  Contaminated solids enter by conduit 207 and stripped solids leave through 211.  Stripping gases are introduced by line 208 and are circulated to the top of the reactor by line 212.  The product leaves the reactor at 203 together with the other gases.  In Fig. 4 the contaminated solids are introduced into an insulated stripping well 232 from the conduit 228.  The conduit 234 maintains the fluid level at 229 and returns excess solids to the reactor and the line 230 is used to return the gases to the top of the reactor.

Title: Improvements in or relating to card position checking means for statistical apparatus
Inventor: WATKIN WILFRID BATEMAN COOK
IPC: G06K13/06
Filed: 1955-06-03
Abstract: 790,133. Selective punching machines. POWERS - SAMAS ACCOUNTING MACHINES, Ltd. June 1, 1956 [June 3, 1955], No. 16050/55. Class 31 (2). [Also in Group XIX] Cards fed through a statistical ma chine are checked for correct location in the sensing position and if correctly placed are formed with a cut-out CO, Fig. 6, indicative of correct positioning. For this purpose, aligning pins are provided to enter holes 6, 7 in the card and a punch is provided to form the cut-out CO, the aligning pins controlling the punch so that if they do not register with the holes 6, 7 they prevent its operation. The cards C to be sensed are delivered one at a time to three stations 1, 2, 3 in succession. In each station, pins 4, 5, Fig. 1, engage the locating holes 6, 7, and a sensing operation takes place in stations 2 and 3. Each pin 4, 5 is supported on a bracket 9 secured to a frame 10 and has a shoulder 11 to bear on the bracket and a spring 13 urging the pin downwardly. The lower ends of the pins extend into bushes 14 in the plate 15 which is the top guide plate for the cards passing through the sensing mechanism. Downward movement of frame 10 therefore causes the pins to descend on the card, the tapered ends drawing the card into perfect alignment if it is in approximate register. If the card is so far out of line that one of the pins cannot enter a hole the pin will be lifted relative to the frame 10. In stations 2 and 3 where there is to be sensing, a punch 27 is provided secured to a guide-bar 28 slidable in a bracket 29 fixed to the frame 10. The frame 10 also carries two rocking spindles 31, Fig. 4, each carrying a latch 32 for engagement with the guide bar to hold the punch against upward movement relative to the frame so that as the frame descends, the punch forms a cut-out in the edge of the card. The spindles 31 also carry arms 33 located over the aligning pins nearer the spindle. The other aligning pin also has a control arm co-operating therewith controlling the spindle through a lever-and-link mechanism. Upward displacement of either aligning pin during downward movement of the frame rotates the spindle 31 and displaces the latch 32 so that the punch is rendered inoperative to form the cut-out in the card edge. The cut-out CO, Fig. 6, is formed in a card correctly located in station 2 and in station 3 it is formed with a second cut-out CO<SP>1</SP>. Cards lacking either cutout are clearly visible when the cards are stacked.
