Title: Improvements in hydroforming
IPC: B01J23/96
Filed: 1955-09-07
Abstract: In a multi-stage process for hydroforming naphthas in the presence of a platinum catalyst a halogen or a halogen-containing compound is added to the feed passing to each stage after the first stage of the process.  The added substance may be chlorine itself or hydrogen chloride or hydrogen fluoride.  The chlorine content of the catalyst is preferably 0.05 to 0.8 weight per cent of chlorine at the first stage, 0.3 to 1.0 per cent to the second stage, 0.7 to 1.2 per cent at the third stage and about 0.3 to 0.7 weight per cent higher for each subsequent stage.  This is achieved by adding 3 to 20 parts of chlorine or other halogen per million to the feed between each subsequent reactor.

Abstract: 384,723. Grates; ashpits. WOOLNOUGH, W. H. and SENTINEL WAGGON WORKS, Ltd., 20, Iddesleigh House, Caxton Street, London. Sept. 16, 1931, No. 25982. [Class 51 (i).] In a boiler or other furnace, more particularly in a steam generator for vehicles, the firegrate is of well form and has its sides and bottom perforate with the bottom separate from the sides and received therein with lateral clearance and carried by depending swing links in such a manner as to be free to rock or tilt bodily relatively to the sides. As shown in Fig. 1, the well sides 12 are of inverted conical form and are joined with and supported from an annular boiler 10 by members 14, 16 which also form shrouds impeding the air flow through the upper edges of the fuel. The grate bottom 13 is formed with a hump extending into the fire and is supported on an upstanding pintle 19 carried by a forked bar 20 supported at the forked end by depending swing links 24, 25 and at the other end by a swing link 23. The bar 20 which also carries an ashpan 17 may be detached from the supporting link 23 and lowered together with the grate bottom by means of lifting tackle including pulleys 30, 31. When the grate is used on a vehicle, the motion of the vehicle will cause the grate bottom to rock and discharge ash. In the form shown in Figs. 3 and 4, means are provided for manually rocking the grate bottom. The bar 34 carrying the pintle 19 is supported at one end by a swing link 35 and at the other end is formed with a fork 36 embracing and supported by the lower end of an oscillatable spindle 37. The lower end of the spindle has a square portion upon which is received a two-armed lever 44 the ends of which are pivoted to rods 51, 52 extending beneath the grate bottom and having forked brackets 55 to engage lugs depending from the grate bottom. The spindle 37 has a screwed portion 38 upon which is received a nut 39 provided with a spherical neck oscillatably seated in a bracket 41 and allowing the spindle to be raised or lowered. A shroud 58 is arranged around the well sides. In the above forms the ashpan is carried by the bar 20 or 34. In another modification, however, the shroud forms an extension of the ashpan which is carried by the boiler 10 and is provided with air apertures fitted with dampers which open under a strong draught, but close when the blast stops, e.g. when the vehicle is stationary.

[Also in Groups XIII and XXV] A controller has an input means responsive to a variable, e.g. temperature or pressure, an output means, e.g. a switch, a shiftable setting means, and a flexible non-extensible linkage means joining the input means with its output means and the setting means. As shown, a lever 49 pivoted at 50 is acted upon by the input means, which may be a bellows assembly 32 and is connected to one end of a metal band 68 which passes over a pulley 71 and is secured to a pulley 73 fixed to an adjusting shaft 60. The pulley 71 is carried by a lever 54 pivoted at 55 and a bracket 72a is arranged to actuate a snap switch 20 when a predetermined temperature or pressure is reached. The right-hand ends of levers 49, 54 are joined by a spring 59 to keep the band 68 taut. A pointer 74, secured to a pulley 75 fast on shaft 60 indicates the setting. The assembly 32 is adjustable lengthways of the lever 49, and contains an ambient temperature compensating bellows, the effect of which may be modified by incorporating one or more steel halls within it, Fig. 2 (not shown). A second switch may be operated after switch 20 by a bracket on a further lever parallel to lever 54, the bracket having a part bearing on the lower face of the pulley 71 Fig. 9 (not shown), or a second lever 54 and, band 68, together with a separate indicating pointer may be used, Fig. 10 (not shown).

The gates 9 are each fitted with wheels 12 running on rails 11, and have a rod 10 articulated to which is a lever 13 pivoted at 14. A further lever 15 rigidly connected to one lever 13 may be rocked into a position 15a whereby both levers 13, which are suitably interconnected, produce opposite movements of the gates 9. As the larry approaches the hopper 5, a U-shaped rail 19 mounted on a coupling rod 17 on the gate operating mechanism 16 engages an offset projection 21 of the lever 15. Motors controlling each mechanism 16 are operated together from the larry cabin 26 to open the gates.
