Title: Process for the constructive conversion of heavy to light hydrocarbons
IPC: C10G47/22
Filed: 1924-02-13
Abstract: 231,625. Shore, W. E. Feb. 13, 1924. Hydrocarbons, cracking.-In converting heavy into light hydrocarbons the heavy oil is atomized in presence of hydrogen or hydrogenbearing gases and the temperature of the mixture is raised by compression. A compressor 2 is operated by an internal-combustion engine 1 the waste gases from which are used in a heater 15. Heavv oil is forced bv a pump 5 through the cylinder jacket 6 and through a jacket 7 of the compressor 2 into a reservoir 9 from which vapours pass by a pipe 11 into the inlet pipe 30 of the compressor. The heated liquid from the reservoir 9 passes through the heater 15 to a pipe 17 in which it is mixed with hydrogen bearing gases from pipes 38, 39 and from which it passes into a rotary nebulizer 3 which is driven from the engine 1. and is surrounded by a jacket 18 through which mercury vapour generated in a vessel 20 is circulated. The nebulized mixture at a temperature of about 250‹ F. is further heated by passage through a coil 23 in the heater 15, and through coils 25 in vessels 26, 27, 29 through which the mixture after compression in the compressor 2 is passed. The mixture heated to about 400‹ F. passes by a pipe 30 into the compressor 2 and is discharged at a temperature of about 800-1200‹ F., through a pipe 31 and through the drums 29. 27, 26 to a series of condensers 32 - - 34 which contain liquids of the gravities to be separated. The vapours pass through expansion valves 32<1> and pipes 33<1> into the liquid. Uncondensed gases, or vapours from the drum 26, may be passed to the nebulizer 3 by pipes 38, 39.

Abstract: 410,574. Loading; shoots ; lifting &c. TOROK, J., 620, Pennsylvania Avenue, and BERGSTRESSER, E. L., 212, 6th Avenue, both in Renova, Pennsylvania, U.S.A. Feb. 9, 1933, No. 4037. Convention date, Feb. 9, 1932. [Classes 78 (i), 78 (ii), and 78 (iv).] A coal discharge shoot in which the direction and rate of discharge of material is controlled from a remote station by suitable electrical controls is characterized by a pivoted gate 13, Fig. 1, at the discharge end regulating the size of the opening 11. A telescopic coal-shoot 1, is provided with an elbow extension 3 which is rotatable by ring gear 4 meshing with a motordriven pinion 5. Coal is delivered at the opening 11 in any direction being deflected on a plate 12. The gate member 13 is operated by a motor 15 and worm gear. Current for the motor 15 is preferably provided from collector rings 16 in association with the ring gear 4 and brushes 17 in fixed relation to the tube 1. The rings and brushes are provided with guards 22 and removable covers 21. Between the motor 15 and worm 36 is a magnetic brake 38 of known construction for withdrawing brake shoes 39, from the motor shaft against a spring 40. The ends of the gate 13 have lugs 41 to engage spring bumpers 42. When the gate is fully closed and a spring 45 is compressed to a predetermined point, the motor 15 becomes overloaded and stops automatically. In the ordinary way however, the motor 15 is controlled before this. The control circuit is shown at Fig. 5 with the motor represented as a threephase one at 15 with conductors 47<a>, 47b, 47<c> collectors rings 16, brushes 17 and a junction box 48. In circuit there is shown a line starter S and a thermal relay T. Push button controls are shown at P and the magnetic brake at 38. When forward push button 50 is pressed against a spring a circuit is closed through main L<2>, coil 54, conductors 55, 56 including contact 57 of thermal relay to L<3>, energizing coil 54 and causing contacts 52<a>, 52b, 52<c> of the line starter to close. Current passes from main L<1> through contact 52<a>, coil 58 of relay T to conductor 47a, collector ring 16 and conductor 72<a> to motor 15. Current also passes from main L2 through 52<b> 47b, and 72<b> to motor and from conductor L' through 52<c>, coil 59 of relay T, 47<c>, 72<c> to the motor. When reverse 51 is operated, the phases of the motor 15 are reversed and its rotation changed. The motor is stopped by pressing button 49 so as to open all contacts of the line starter. When the motor is going, and the gate 13 touches the bumpers, the motor 15 becomes overloaded and the thermal relay T is excessively heated whereupon elements 67 are flexed so as to move a cross arm 68 and contact 69. This opens a contact 57 and stops the motor. When the motor is stopped, current to the brake 38 is shut off and springs 40 on stop 39 retard movement of the gate. By revolving the bucket 3 with the gate 13 partially open, material is spread evenly in layers instead of pyramiding.

Inventor: KILLINGER ARDEN HOLMES
IPC: A61K39/187
Filed: 1952-02-16
Abstract: In the preparation of a vaccine for immunizing swine against hog-cholera, hog-cholera virus is attenuated by transfer through, say, 13 to 15 animals other than swine, e.g. rabbits, a saline suspension of the animal tissue, e.g. spleen, or defibrinated blood, is parentally administered to a hog, and after a temperature rise of the hog, the blood and/or tissue harbouring the attenuated virus, e.g. spleen, liver, or testes are separated, and the vaccine isolated therefrom.  Thus, the blood may be defibrinated and rendered sterile by the addition of phenol, or the tissue is ground and screened.  It may then be dried for subsequent reconstitution, or be buffered with an isotonic solution or admixed with glycine, lactose, &c.  Other active substances may be added; thus, the defibrinated blood, or blood sera, or ground tissue may be made up with crystal violet and glycerol, or antiseptics such as phenol, other dyes such as methylene blue or acriflavine, sulphamethazine, suphamerazine, sulphaquinoxaline, antibiotics, gammaglobulin, &c. may be added. The product may be administered orally or parentally, if desired in conjunction with anti-cholera serum.
