Title: A continuous process for the thermal decomposition of a gaseous or vaporous hydrocarbon to coke and hydrogen
IPC: C01B3/28
Filed: 1959-12-29
Abstract: <PICT:0883751/III/1> In a continuous process for the thermal decomposition of a hydrocarbon at the surface of heated coke in a fluidized or moving bed to deposit carbon on the coke and produce hydrogen, a portion of the coke is recycled to the process after preheating by passage downwards through a burner vessel first in the freely falling state, and then as a moving bed, in countercurrent to air injected into the vessel both above and below the moving bed so as to form carbon monoxide by partial oxidation of the coke in the moving bed and burn the carbon monoxide above the bed without substantial oxidation of the carbon in the freely falling state. The air may be preheated by indirect heat exchange with the combustion product gas.  The hydrocarbon may be preheated by indirect heat exchange with the product hydrogen gas to 1000 DEG  F. in a conventional tubular gas heater or to 2000 DEG  F. in a regenerative system in which coke particles are recycled between heat absorption and recovery vessels.  The hydrocarbon may be in the form of natural gas, naphtha or refinery tail gas from which hydrogen sulphide, oxygen, carbon monoxide and carbon dioxide have been removed.  The hydrocarbon-decomposing coke particles may have a particle size of 1/16 -1 inch, preferably 1/4 inch, the moving bed may have a depth of 1/2 -6 feet, preferably 1-2 feet, and the coke particles may fall freely for 10-90 feet, preferably 30-50 feet.  The coke particles may be heated to 2000 DEG 3000 DEG  F., preferably 2400 DEG  F., in the burner vessel.  As shown, coke particles are recirculated to a burner vessel 20 from a line 6, a cracking vessel 5, lines 8 and 10, an air lift 14, a storage hopper 15 and a line 16.  Air is injected into a moving bed 19 in vessel 20 from a line 25 and above the bed from a line 24, and combustion product gases are removed from the vessel via a line 26.  The enlarged coke particles from vessel 5 are reduced in size in line 8 and the fines are removed as product through line 9. The product hydrogen passes from cracking vessel 5 via line 7 to a heat recovery vessel 28 up which it passes in countercurrent to coke particles which are recycled to the vessel via line 3, hydrocarbon preheat vessel 2, line 29, bucket lift 30, line 31, hopper 32, and line 33.  The hydrocarbon passes to cracking vessel 5 via line 1, preheat vessel 2 and line 4. Conditions in the various vessels are specified.

Title: Electroluminescent device
IPC: H04N9/30
Filed: 1967-09-28
Abstract: 1,201,377. Electroluminescence. XEROX CORP. 28 Sept., 1967 [29 Sept., 1966], No. 44131/67. Heading C4S. An electroluminescent device 10 comprises a layer 14 of variable impedance material comprising a plurality of sections 22 . . . 26, each responsive to light of a particular colour, the layer having an image receiving exposed surface and overlying a plurality of sections 17 . . . 21 of electroluminescent material each emitting a particular coloured light and a plurality of spaced electrodes 11 supported on a substrate 12, each electrode being in contact with at least two distinct sections of electroluminescent material. In a display panel, layer 14 may be a field effect semi-conductor or a photoconductor and the sections may be sensitive to the coloured light emitted by the electroluminescent material beneath. The sections are perpendicular to the electrodes. A potential is applied between adjacent electrodes such that when the incident image produces variations in the impedance of layer 14 there is a variation in current between adjacent electrodes and in the light output of the electroluminescent material. When the layer 14 is a field effect semi-conductor its surface is either charged with an image pattern or it is uniformly charged then illuminated with the light image causing areas of charge to be removed as the conductivity of illuminated areas is reduced. The base 12 of the panel may be of glass or polyethylene terephthalate but may be opaque; a filter may be placed in front of layer 14. Portions of the electroluminescent material between electrodes which do not appreciably emit light may be replaced by insulating material or adjacent sections separated by an opaque layer. Another opaque layer can be inserted between layers 13, 14. In another embodiment, to provide a high contrast output image from a weak input image wherein the colour varies with the intensity of light a portion of each electrode is covered by a section of one phosphor narrower than the electrode and each edge of the electrode is in contact with another phosphor. Layer 14 may be a field effect semi-conductor, e.g. ZnO, PbO, CdO and Rochelle salt or a photoconductor, e.g. CdS, CdSe, Se and Se alloys containing As or Te. Electroluminescent materials are ZnS: Cu; ZnS: Cu, Mn; and ZnS, HgS: Cu mixed with a transparent binder of epoxy or P.V.C. resin. The sections are deposited by spraying through a mask.

Title: Delay-timing device for unlocking safes or the like
IPC: G04G15/00
Filed: 1976-11-15
Abstract: A microswitch, which is closed by means of a key, actuates a time switch adjustable to 5 to 30 minutes and indicates visibly the time required for opening the safe. After this time has elapsed, it automatically actuates a time switch adjustable to 1/2 to 2.5 minutes. At the same time, the visible indication is switched off and a buzzer is actuated. A solenoid makes it possible to open the safe in this short time. During this opening, the supply of energy to the system is put out of operation. When the door is then closed, it is locked by means of the solenoid and the opening procedure has to be recommenced. If the door is not opened during this short time, the actuation of the time switch having the long timespan takes place automatically; the system thus remains in the stand-by state, until the safe door can be opened again. The system serves for providing special security measures during the opening of safes of banks or other institutions.

[Also in Division H1] A power-operated tool 16 for driving fasteners comprises a driver 26 actuated by a power device 50 and movable in a track 25 for driving fasteners supplied from a magazine 21, a manually-actuable first control 80, 82 for the power device, and a second control 40 responsive to the quantity of fasteners in the magazine, both controls being included in a control means for causing the power device to operate when the first control is actuated provided that there is an adequate supply of fasteners in the magazine. The power device is constituted by a solenoid winding 50 mounted in a casing 45 forming part of a nosepiece assembly 24, the casing being slidable, at one end, on a spigot 20d formed on the housing 20 and guided, at the other end, by screws 48 running in slots 47 provided in the casing. A spring 75 normally urges the lower end of the casing into contact with the nosepiece 24 at the front end of a housing portion 21 containing the fastener magazine so that, when the tool is operated, the nosepiece stays in contact with the work while the recoil is taken up by movement upwardly of the casing 45. The armature 58 of the solenoid is returned to its normal position by means of a spring 65, the armature having a collar 71 for abutment with rubber stops 70, 72 at the ends of the working and return strokes respectively and for drawing cooling air through ports 76; alternatively, the armature may be returned by means of a second winding secured to the housing. The control means 40 is in the form of a switch which is normally closed when the magazine 21 is full but is opened by means of a projection 39a on a pusher 39 when less than three fasteners are left in the magazine. A safety switch 38 is provided in the electrical circuit in order to prevent actuation of the tool until the nosepiece is in contact with the workpiece, a slidable member 33 being arranged to actuate the switch. A control unit is provided which houses circuitry for applying varying degrees of electrical energy to the winding in order to emit varying lengths of fastener and different hardnesses of material. The particular power required is set by means of a switch 90 connected to the control unit. Circuitry may also be provided for causing the tool to operate continuously without the necessity for operating a trigger controlled switch 82 after every stroke.
