Title: An improved process for catalytic treatment of hydrocarbons
IPC: C10G11/18
Filed: 1940-05-02
Abstract: 543,838. Cracking oils. STANDARD OIL DEVELOPMENT CO. May 2, 1940, No. 7879. Convention date, July 26, 1939. [Class 32] In catalytic cracking processes of the kind in which powdered catalyst is injected into a stream of hydrocarbon vapours and the suspension is passed through a cracking zone heated to the required reaction temperature the catalyst is separated from the cracked products in a plurality of stages at a temperature sufficient to prevent any substantial condensation of the conversion products. The preheated vaporized oil fed through line 10 is formed into a suspension with the catalyst in an injection chamber 11 into which catalyst from tower 66 is injected by means of a jet 71 of steam, hydrogen, or inert gases. The suspension passes through line 12 to a reaction chamber 13 provided with longitudinal segmental baffles 14, 15 or tubular baffles (Fig. 3, not shown). The reaction products pass through line 17 to a cyclone separator 18 from which the separated catalyst is passed by conveyer 19 into tower 29. Further separation of catalyst is effected in a second cyclone separator 112 and in an electric precipitator 115 from which the vapours pass through line 116 to condensation apparatus. The catalysts separated in the various stages are fed to the stripping chamber 22 of the tower 29 where the catalyst is purged with inert gases fed through line 24 and perforated tubes 26 located below baffles 25. The purged catalyst is fed through valved opening 28 into the middle of tower 29 where it is mixed with fresh catalyst fed from hoppers 127, 128 and thence through valve 31 into the lowest chamber 33 of the tower. The valves 27, 31 and gas lines 30, 34, 35 permit differential pressures to be maintained in the various chambers. Purging vapours are recovered through line 120 and separated from catalyst in cyclone 121. The catalyst is then injected by gases supplied through injector 42 into the bottom of a regenerator tower 45 provided with baffles 46, 47, 48 having slotted openings 49, 50, 51 and supplied with regenerating and cooling gases through lines 58, 59, 60 so that the temperature of regeration is maintained below 1000‹F. The regenerated catalyst and gas stream is passed through line 61 to cyclone separators 62, 73 which separate the catalyst from the gases and feed the catalyst to the tower 66 which is of similar construction to tower 29 and in which the catalyst is purged with inert gases fed through line 67. The used regeneration gases taken off through line 75 are passed through heat exchangers 76, 81, 83 from which fractions reduced to the required temperatures are pumped to the regeneration tower and injector 42. Residual catalyst may be removed by passage through an electric precipitator 89. The gases may be burnt in a combustion chamber 106 and then fed with or without cooling to the gas supply lines 79, 86, 98.

Title: Improvements relating to resinous compositions
Inventor: ANDERSON JAMES THOMSON
IPC: C08J3/215
Filed: 1952-01-21
Abstract: A solid resinous composition containing a dispersion of silica is made by mixing a colloidal solution of silica in an organic solvent and a solution of a resin in an organic solvent, precipitating the resin as a solid gel by addition of ammonia, breaking up the gel, subjecting it to atmospheric drying, and grinding it to a powder. The resin used may be either natural, e.g. shellac, or artificial, e.g. phenol-formaldehyde, urea-formaldehyde, acrylic or "Glyptal" (Registered Trade Mark) resins.  The colloidal silica solution may be produced by hydration of ethyl silicate.  Other inorganic compounds may be introduced into the silica-resin solutions, such as metallic chlorides, e.g. magnesium or copper chloride, as solutions in organic solvents, e.g. alcohol, and the whole gelled by addition of ammonia solution.  Such colouring matters as ultramarine, organic dyestuffs or fluorescent compounds, may be added.  The particles of the powdered product may be coated with a layer of protective material, as described in Specification 521,099, [Group XL].  If the resin is thermosetting, it may be cured.ALSO:A solid resinous composition containing a dispersion of silica is made by mixing a colloidal solution of silica in an organic solvent and a solution of a resin in an organic solvent, precipitating the resin as a solid gel by addition of ammonia, breaking up the gel, subjecting it to atmospheric drying, and grinding it to a powder.

Title: Control system for electric brakes
Inventor: BELTRAMO RENALDO MARIO
IPC: B60T13/74
Filed: 1969-02-14
Abstract: 1,254,597. Brake control circuits; electricallycontrolled brakes. SYNCRO CORP. 14 Feb., 1969, No. 8310/69. Headings F2E and F2F. [Also in Divisions H2 and H3] In a tractor-trailer combination, the electric brake system of the trailer is subject to the same pedal control as the fluid brake system of the tractor and is independently actuable by a hand control, and if, for example, the hand control is set to provide a preselected amount of braking on the trailer, upon application of the foot control, additional braking of the trailer will occur only after the originally preselected braking magnitude set by the hand control has been reached. As shown, when trailer braking only is required, the hand control effects movement of the wiper of a potentiometer R1 to cause transistor Q1 to conduct and send a signal through potentiometer R8. Transistor Q4 then conducts, causing power transistors Q5, Q6 to conduct and supply a signal to the brake coil C. Assuming now that pedal control is effected to move the wiper of a potentiometer R2. Transistor Q2 will not increase the signal to potentiometer R8 until the base bias of Q2 is sufficient to overcome the positive potential at its collector due to the base of Q1 being connected to the collector of Q2. Since transistors Q1 and Q2 are similarly connected, the operation is similar to the above if pedal control is applied first. A short-circuit control section 28 is provided, a transistor Q3 being conductive and a transistor Q7 being non-conductive. Should lead 30 be short-circuited to ground, Q7 becomes conductive thus turning off Q3 and rendering Q1 and Q2 non-conductive. In this way Q6 is prevented from burning out. The circuit 28 may be omitted, Q6 then being protected by connecting the negative lead 22 to ground and the positive lead 20 to the positive side of the battery B. Alternatively, the connections of coil C and transistor Q6 to the leads 20, 22 may be reversed to provide protection for Q6. In a modified arrangement, Fig, 5 (not shown), the calibration potentiometer R8 may be omitted and calibration may be provided by a transistor (Q8) connected between transistors Q4 and Q5, a variable resistor (R18) being provided between the lead 20, connected to the positive side of the battery, and the connection between the collector of Q4 and the base of (Q8).
