Title: Power transmission system in connection with compound expansion internal combustion engines
IPC: F02B41/10
Filed: 1936-11-24
Abstract: 485,755. Motor power plant. TOTH, C. J. Nov. 24, 1936, No. 32110. [Class 110 (iii)] [Also in Group XXVII] A power plant consists of a compound internal-combustion engine having a lowpressure portion driven by the exhaust gases of the high-pressure portion, which may be disconnected from the load and continue to serve as a power gas generator. The high-pressure portion A of the power plant, Fig. 1, consists of a two-cylinder supercharged internal-combustion engine having working cylinders B<1> and B2 each incorporating a corresponding compressor cylinder I<1> and I<2>. The exhaust from this portion of the plant is led to a lowpressure portion T through a pipe S to which is connected a storage receiver R controlled by a valve Q. The engine T is geared to the shaft O which drives the road axle D. A releasable coupling C connects the main shaft M of the high-pressure portion A to the driving shaft O. To start the plant, the engine A is started up as a self-contained unit, and the receiver R charged with compressed gases. The lowpressure portion T is then started up with gas from this receiver, and as the vehicle gathers momentum more gas is supplied partly from the engine and partly from the receiver. When the speed of the vehicle is sufficient, the clutch mechanism C is engaged and both portions A and T of the engine are connected to the driving axle. The high-pressure engine portion may be either a two- or four-stroke internal-combustion engine and the low-pressure portion may consist of one or more gas turbines.

Title: Thermoplastic synthetic resins
Inventor: KAUFMAN MORRIS
IPC: C08F12/32
Filed: 1949-12-15
Abstract: Acenaphthylene is polymerized alone or with a compound containing at least one CH2=C< grouping in which the single linkages are attached to dissimilar radicals such as styrene, acrylic acid and its esters, and methacrylic acid and its esters, other than a compound in which a heterocyclic ring containing oxygen occurs, in an aqueous medium containing a protectve colloid suspension stabilizer, and optionally a polymerization catalyst such as benzoyl peroxide.  Suitable suspension stabilizers are heavy metal soaps, starch, agar-agar, gum arabic, gelatin, pectin, alginates, various cellulose compounds, polyvinyl alcohol, finely divided oxides, fuller's earth, talc, and bentonite.  The polymers are produced in bead form either by employing an amount of suspension stabilizer sufficient to form a suspension which is a viscous gel in which case only initial agitation of the reaction mixture is required to form discrete droplets of monomer which are then polymerized, or a thin suspension medium is employed in conjunction with constant stirring during the reaction.  The preparation of polyacenaphthylene with a softening point above 200 DEG  C. is described.  Specification 653,718 is referred to.

Title: Process of converting liquid hydrocarbons into hydrocarbons of lower boiling-point
Filed: 1919-12-24
Abstract: 160,907. McComb, W. M. Dec. 24, 1919. Hydrocarbons, cracking; film evaporators; progressive evaporators. - In the production of low-boiling hydrocarbons, high-boiling hydrocarbons mixed with steam are passed downwardly through a coil or coils 8, 9, Fig. 1, heated at the base and having a pitch which increases from top to bottom. The products are condensed, and the condensate is fractionated in a still 40 comprising an inclined surface, successive zones of which are heated to successively higher temperatures. The steam is generated in a coil 18 and is mixed with the pre-heated hydrocarbons by means of such as spiral blades, at the inlets to the coils 8, 9, which impart a gyratory motion to the mixture entering the coils. At the exits from the coils, the mixture passes over bodies 26, 27 of high specific heat, e.g. finely divided nickel or molybdenum or its alloys. The products pass through a single conduit 28 at an accelerated velocity to a condenser 4 in which the crudehydrocarbon is pre-heated. The uncondensed products are led through a scrubber 33 to a reservoir. The condensates are pumped through a pipe 38 to the still 40, whence the low-boiling vapours flow to a condenser 52, the residues being returned for re-treatment. In the still, Fig. 3, the liquid flows over ripples 41 extending transversely of the inclined platform 40, which is heated by the hot gases from the furnaces of the coils 8, 9, 18. The hot gases are led by conduits 43, 45 into compartments formed by partitions 46 below the platform 40, and are afterwards discharged to the atmosphere by a fan 49. The temperature is controlled by the admission of cool air to the compartments by means of valved apertures 47. The platform 40 is enclosed by a casing 40<1> provided with conduits 58 leading the vapours to a conduit 51 communicating with the condenser 52.
