Title: Process and apparatus for the production, without catalyst, of synthesis gas from concentrated gaseous aliphatic hydrocarbons and oxygen
IPC: C01B3/36
Filed: 1955-09-27
Abstract: <PICT:0783141/III/1> <PICT:0783141/III/2> <PICT:0783141/III/3> In the production of synthesis gas by the noncatalytic interaction of a gaseous hydrocarbon, e.g. methane and oxygen, the reactants are premixed and passed into the reaction chamber in streamline flow parallel to the axis of the reaction chamber by mutual impact of the two gas streams, the components of the kinetic energies of the two streams perpendicular to the general flow of the resulting mixture being substantially equal.  Using methane the O2/CH4 ratio may be 0.5-8, e.g. 0.72. The reaction takes place in the absence of other gases, e.g. inert gases or steam, without the formation of carbon black, and at a temperature below 1000 DEG  C.  As shown in Fig. 3, oxygen and hydrocarbon gas are admitted to an annular mixing chamber defined by a sleeve 17 and a double-cone valve 19 from flared inlets 11 and 12 respectively.  The resulting mixture passes out of an outlet in the mixing chamber (Fig. 4, not shown).  The double-cone valve is operated by a graduated hand-wheel 20 so as to oppositely vary the sizes of the inlet opening for the oxygen and hydrocarbon. The double cone may divert each gas through an angle of 35 degrees. The velocity of the resulting gas mixture may be 20-120 m/sec.  As shown in Fig. 5, hydrocarbon gas passes through a tube 22 and around a helix 23 which terminates in a cone.  Tube 22 has a portion perforated by annular series of holes 25 which is surrounded by a jacket 27 having an oxygen inlet 26.  Each hole is inclined to the axial plane containing the hole in a direction opposite to the pitch of the helix, e.g. at an angle of 35 degrees, and is also inclined to a plane normal to the axis of tube 22, e.g. at an angle of 11.5 degrees.  The velocity of the resulting gas mixture may be 15-100 m/sec.  The mixture from either of the embodiments shown is passed to a burner tube 1 (Fig. 1) which is provided with a safety diaphragm 4, a double water jacket 7 having inlet 8, outlet 9 and cylindrical baffle 10, and cruciform partitions 5 and 6 offset in relation to one another (Figs. 2 and 21, not shown).  Specification 702,035 is referred to.

Abstract: 1394364 Controlling ignition of burners ENERGY EQUIPMENT CO Ltd F A BURROWS A B PRITCHARD and I H CLINCH 15 June 1972 [15 June 1971] 27993/71 Heading F4T A safety device for a hydrocarbon fuel combustion appliance comprises a detector capable of sensing the presence of hydrocarbon gases or vapours in the combustion zone, and means connected to the detector for inhibiting the commencement of an ignition sequence if, and so long as, the detector senses the presence of unburnt hydrocarbon fuel. The detector C is located at the opposite end of the combustion zone F from the burner and on operation of fan J receives a sample of the combustion zone contents. If no gas/vapour is detected the detector C causes a signal to be sent through a relay K and contacts K1 to a control D which initiates the ignition sequence by actuating igniters L and opening pilot fuel inlet valve M. If gas/vapour is detected no signal is transmitted and if after a pre-set time the detector still senses the gas/vapour a time delay relay opens contacts G1 to stop fan J, cause the appliance to become inoperative and actuate a visual or audible alarm. The control system may be pneumatic or hydraulic instead of electric. If a fan is not included, a pump may be provided for continuously feeding a sample of the combustion zone contents to the detector. The detector may also be capable of detecting carbon monoxide so that a visual or audible alarm may be given if the fuel/air ratio becomes out of adjustment.

Title: Means for maintaining the weight of the dispensed material constant in dosing and similar machines which operate on a volumetric basis

IPC: G01G13/00
Filed: 1957-09-09
Abstract: 818,288. Automatic control systems for dispensing apparatus. HESSER, MASCHINENFABRIK A.G., F. Sept. 9, 1957, No. 28379/57. Class 38 (4). In means for maintaining constant the delivered weight of dispensed material in volumetric measuring machines, a device measures out sample portions diverted from the feed supply and delivers them to a control device at the appropriate time to provide corrective adjustment of both the dispensing means and the measuring-out device. Fluent material is fed through pipe 1 into chamber 11 the lower part of which is rotatable on shaft 6. The material fills cups D which are constructed of two telescopic cylindrical portions 2, 2a and closed by flaps 30. The cups are adjustable by movement of support 7 up or down shaft 6 through motor 17-operated linkage 18, 19. This movement is also imparted by link 5 to a further adjustable cup 4, 4a situated in a branch 3 of the feed pipe. This is the check-weighing measuring- out cup and is regulated by slides 8 and 9. The measured volume of material is passed to holder 10 attached to a weigh-beam 12, any weight discrepancy causing energization of controller 16 through one or other of contacts 15. The weighed sample portion is discharged through opening 13 into the dispensing chamber. The system is arranged so that a change in density in the material passing through the feed pipe effects, through the controller and, if necessary, with a delay, an adjustment in the volume of the dispensing cups as the changed density material reaches them, thus maintaining a constant dispensed weight. Linkage 5 provides follow-up control of the measuring-out device. In Fig. 3 (not shown) the measuring-out device is similar, but the dispensing chamber is replaced by a delivery screw and the cups by a dispensing screw the speed of the latter being varied by the controller. In Fig. 4 (not shown) is a further embodiment in which the delivery means, the measuring-out device and the dispensing means all utilize screw feeds. The weigh beam, instead of moving between contacts, may be arranged to operate photo-electric, capacitive or inductive detecting devices.

An externally screw-threaded member 30 within tube 22 is secured from endwise movement by a grub-screw 31 and engages with an internal screw-thread on member 22 so that by rotating a key 32 engaging with a pin 33 the length of the telescopic member is varied. A rod 34 slidably engaged on member 30 has a handle 35 which may be foldable, and at the opposite end an enlargement 36, (Fig. 2, not shown), which can be brought against the end of tube 37, secured in one end of the telescopic member. In a modification, shown in Fig. 3 the rod 34 has a bifurcated end 38 which engages a pin 39 equivalent to pin 33 in Fig. 1, and functions as a key.

Title: Apparatus for counting moving objects of electrically conducting material

Filed: 1957-09-09
Abstract: 872,941. Electric tests. UNITED STATES STEEL CORPORATION. Sept. 9, 1957 [Dec. 26, 1956No. 28415/57. Class 37. The passage of objects of magnetic material or of discontinuities in magnetic material is arranged to vary the magnetic coupling between a first coil and each of a pair of other coils in sequence, the outputs of this pair of coils being compared. As shown (Fig. 1), sheets S to be counted are passed by a conveyer 2 beneath a coil 4 fed from an oscillator 12. The passage of an object successively varies the coupling between coil 4 and each of coils 6, 6a, which are connected to a differential amplifier 16, 42 of known type. The output of the amplifier is fed to a phase discriminator which also receives a reference signal from oscillator 12. The discriminator feeds the grid of a triode 24 in the anode of which is a relay operating counter 30. The arrangement is such that when the sheet to be counted shields coil 6 from coil 4 a difference signal is produced by the amplifier which is used to operate the counter. The effect of the phase discriminator is to eliminate the double count produced as the sheet leaves the coil assembly. The oscillator may feed a pair of coils in series, a single coil only being used to detect the passage of the sheets (Fig. 2, not shown). In this case the output of the coil is amplified by a single triode and connected directly to the phase discriminator.
