Title: Process for the production of gases rich in olefins from hydrocarbon oils
IPC: C10B55/06
Filed: 1956-03-20
Abstract: 789,049. Oil gas; purifying oil gas; material for making coke. BERGWERKSGES HIBERNIA AKT.-GES., and KOPPERS GES., H. March 20, 1956 [March 24, 1955], No. 8696/56. Class 55 (2). In a process for producing gases having a high olefine content by thermal conversion of hydrocarbon oils the hot conversion products are brought into contact with a moving mass of cold, wet coal to condense the liquid hydrocarbons contained therein. The coal employed may be a coking coal and the coal may be subsequently coked. In the Figure, cold, wet coking coal is fed from a hopper 1 to a container 3 having an agitating device 4, 5 and from which the coal is fed to a treatment chamber 7 where it is contacted with hot reaction products from a reaction chamber 17. The treated reaction products leave by a pipe 22 and the coal descends a tube 8 into a lower vessel 9 containing an agitating device 11 and finally into a receiving hopper 13. The tube 8 is movable so that the depth of the bed of coal through which the reaction products pass may be varied. The thermal conversion of the hydrocarbon oil is effected by injecting the oil in finely-divided form into a hot carrier gas produced in a burner 18 supplied with oil and oxygen. The carrier gas may have a temperature of 1500-1600‹ C. but if it is particularly desired to produce the temperature of the carrier gas is reduced to 850-1000‹ C. by the addition of a cold gas through a pipe 19.

Title: A method of and means for controlling and determining exposure in photographic printing apparatus
IPC: G03B27/16
Filed: 1925-04-07
Abstract: 244,319. Crookes, W. D. April 7, 1925. Printing apparatus.-Apparatus having a timing device for automatically controlling the duration of exposure is provided also with two adjustable controls, one of which comprises a rheostat for varying the printing light, and the other means for moving the lamps towards and away from the negative. The time of exposure is constant: the rheostat is used for varying the light in accordance with the speed of the paper printed, and the position of the lamps is adjusted according to the density of the negative. Different batches of paper can be standardized by determining the rheostat setting for a satisfactory print from a standard negative with the lamps at a certain distance therefrom. In the form described, the timing clockwork mechanism 13, Fig. 1, has a winding arm 15, and is set on the upward movement of the platen 2 through a crank arm 9, a slide 8, and a projection 16 thereon which acts on the arm 15, the latter being held by the resilient armature 11 of an electromagnet 10, which, together with a tumbler switch 5 and the variable rheostat 22, is in the lighting circuit 1, Fig. 3. The switch 5 is also closed on the same upward movement of the plates by another projection 7 on the slide 8. On closing the platen to make a print, a press button switch 1 is closed, thereby completing the lamp circuit and energizing the electromagnet 10 to release the arm 15 from the armature 11. This arm 15 moves slowly, and after the exposure interval operates the arm 6 of the switch 5 to open the lamp circuit. An additional switch 24 in shunt across the switch 5 and electromagnet 10 can be used to render the timing mechanism inoperative if desired. The vertically adjustable slide 31 carrying the lamps 30 may be be counterbalanced by a weight 26 and connected with the indicator 39 moving over the scale 40 on the control panel 41.

[Class 2 (iii)] [Also in Group V] Condensation products of hydroxyacetic acid useful in baking powder compositions are obtained by heating hydroxyacetic acid or a partially dehydrated product thereof under atmospheric or higher pressure until not more than 25 per cent. of the initial combined water in the hydroxyacetic acid remains and then heating under vacuum to remove the major portion of the residual combined water and the volatile low molecular weight substances. Preferably the first stage is carried out by heating to 180‹-230‹ C., and the second stage between 210‹-250‹ C. at a pressure of between 5 and 100 mm. The first stage may be carried out under pressures up to 10 or more atmospheres, if desired in the presence of an acidic catalyst, e.g. phosphoric, sulphuric or p-toluenesulphonic acids. The second stage is preferably carried out whilst introducing an inert fluid, e.g., nitrogen, hydrogen, carbon dioxide, benzene or toluene, and towards the end a dehydrating agent, e.g. phosphorus pentoxide or calcium oxide may be added. Starting materials in addition to aqueous solutions of hydroxyacetic acid of all strengths including the partially dehydrated acid such as 110 per cent. hydroxyacetic acid are diglycollide, hydroxyacetic anhydride and esters such as methyl hydroxyacetate (which latter may first be hydrolyzed with water and the product concentrated under atmospheric pressure). ). In the Specification as open to inspection under Sect. 91 the ability of the product to liberate acid slowly in the presence of water and give carbon dioxide in the presence of a carbonate or bicarbonate at high temperatures is described. It may be employed in making gaseous cellular products such as soap, cement, plaster, rubber and plastics. This subjectmatter does not appear in the Specification as accepted.
