Title: Hydrogenation of aromatic hydrocarbons to the corresponding satu rated hydrocarbon
IPC: B01J23/00
Filed: 1973-05-25
Abstract: 1383166 Hydrogenation of aromatic hydrocarbons TEXACO DEVELOPMENT CORP 25 May 1973 [27 June 1972] 25276/73 Heading C5E Saturated cyclic hydrocarbons are produced from an aromatic feed by partially hydrogenating the feed in a first hydrogenation zone using a catalyst comprising an iron group metal (e.g. Ni) on a refractory inorganic oxide (e.g. alumina, silica, zirconia or magnesia) and then hydrogenating the effluent at a higher temperature in a second hydrogenation zone using a catalyst comprising a noble metal (e.g. 0À01-2 wt. per cent Pt) on a refractory inorganic oxide (e.g. alumina) containing 0À01-5 wt. per cent alkali metal. The aromatic feed can contain benzene, toluene or xylene and can be obtained by catalytic reforming followed by solvent extraction and contacting with a molecular sieve to remove water and n-paraffins. The hydrogen used can be purified cryogenically. The temperature in the first hydrogenation zone can be 200-480 F. and that in the second zone can be 480-675 F., the pressure in both zones is suitably 300-800 p.s.i.g. Saturated product can be recycled to the first and/or second zones and a portion of the aromatic feed can be passed directly into the second zone to facilitate temperature control. In the examples cyclohexane is produced from benzene.

Filed: 1925-10-12
Abstract: 258,097. Grimble, F., Caird, W. N., and Coombs, E. Oct. 12, 1925. Density separators.-In a centrifugal separator for liquids, the outlet controlled by the weir is provided with a movable dam by which the passage can be opened or closed. The bowl 1 has a cover 2 enclosing the top plate 8; the heavier component of the liquid travels up between the plate and cover to the weir 12, while the lighter component passes inside the plate 8 and up the outlet 10. The dam 13 is secured to a sleeve 15 threaded into the neck 17 of the cover 2. The dam may be raised to open the passage so that the machine can be used to separate two liquids, or lowered to 'close the passage so that the machine can be used as a clarifier. In the latter case all the liquid is discharged through the outlet 10. The dam 13 and sleeve 15 are locked in position by a ring 19 on the outside of the neck 2. A packing ring 20 forms a seal for the dam 13.

Title: Improvements relating to machines for joggling shaped metal or metal profiles
IPC: B21D11/18
Filed: 1958-08-08
Abstract: 852,567. Angular bending. KONINKLYKE NEDERLANDSE VLIEGTUIGENFABRIEK FOKKER N.V. Aug. 8, 1958 [Aug. 19, 1957], No. 25583/58. Class 83 (4). A machine for joggling metal profiles is characterized in that at each side of the place where a profile is to be joggled, a clamp tightly holds the profile over the whole circumference of its cross-section, the clamps being moved with respect to each other both in the longitudinal direction of the profile and in a direction at right-angles thereto to effect joggling. A profile 1 is gripped at each of two positions spaced therealong by a clamp including blocks 3, 3<1>, 4 cast of low melting-point alloy and shaped to the profile at their combined inner faces and with a frusto-conical combined outer face. Rings 13, 14 on forks 17, 31 urged by pneumatic cylinders 23, 37, press the blocks 3, 3<1>, 4 into conical bores 15, 16 of supporting rings 11, 12 to grip the profile. The clamp support-ring 11 is adjustable longitudinally by a screw 26 acting on a frame 24 which supports the ring 11. The other clamp supportring 12 is carried by parallel pairs of rods 28, 29 pivoted at one end to the ring 12 and at their other end to fixed frame members 30. The clamp ring 12 is moved up and, as a consequence of the parallelogram linkage 28, 29, away from the clamp ring 11, by a wedge 42 moved axially, by pneumatic cylinder 43 of adjustable stroke, between a fixed roll 40 and a roll 38 on the ring 12. This forms a joggle 2, Fig. 1a, in the profile between the clamps. The profile may be heated by electric current passed therethrough from the clamp blocks 3, 3<1>, 4, which are insulated from the machine by coatings 44, 45 on the rings 11, 12 and insulated journals for the pressure-rings 13, 14. The heating current may be automatically switched off on a predetermined temperature being reached, whereupon the joggling is automatically effected. The profile may be additionally supported by an. extension of one clamping block above the profile and the extension of the other below the profile. The clamping blocks may be thermally, and electrically insulated from the profile.

The proximal ends of lumens 18, 22 open into a Y-shaped connector 12, one branch of which leads lumen 18 to a suction pump, the other branch leading lumen 22 to a bacteria filter 24 having a continuation tube open to the air. The diameters of round apertures 20 are smaller than that of lumen 18 to prevent blockage of the latter when suction is applied by the pump. Filter 24 may be replaced by a medicament dispenser e.g. for anticoagulant. Lumen 22 opens into lumen 18 between apertures 20 and the end 14. The device is of clear, medical grade silicone rubber, thermoplastics or vulcanisable material and may be extruded and/or moulded.

Abstract: 595,199. Telemotor systems. SPERRY PRODUCTS, Inc. Dec. 29, 1944, No. 26097. Convention date,March 7. [Class 69 (ii)] A single pipe-line telemotor system has a main pipe C, D, E and an auxil…try pipe G used as a " shadow " line for temperature correction, and also as an auxiliary line if the main line fails. Temperature expansion of liquid in line G moves piston 56 and hence piston 43 to increase volume 40. If the main line C, D, E fails, valves 51, 71 are turned, thus releasing pressure in line G and allowing spring 62 to move pistons 43, 56 to the right, closing port 45 and opening port 73. If the auxiliary line fails, temperature correction ceases, and valve 53 moves to the right to open port 76. In a modified form, the auxiliary line is automatically connected up. Valve 31 opens connection to the reservoir for making up leakage. Specifications 419,310 and 516,752 are referred to.

Abstract: 1464417 Interrogator responder systems SIEMENS AG 17 June 1974 [15 June 1973] 26160/74 Heading H4L In a microwave interrogator/responder system in which a multi-place piece of data is transferred from the responder in response to a swept microwave signal from the interrogator transmitter, the responder incorporates resonators tuned to frequencies with discrete ranges each corresponding to a respective place of the piece of data, the resonators being coupled along a microwave line (a hollow waveguide) in substantially optimum resonance positions. The sequence along the microwave line will determine the time at which each resonator responds and will not normally correspond with the place positions to which the resonators relate. The system therefore incorporates in the interrogator receiver place stores to store the values in the order received from the interrogator and a collator to re-arrange the place order of the values after an interrogator scan has been performed. Two possible responder arrangements are diagramatically indicated (Figs. 3 and 4 not shown), and two possible logic arrangements for the collator are described in outline (Figs. 6 and 7, not shown).
