Oil gas.-Gaseous and easily condensible olefines, benzines and aromatic hydrocarbons are obtained from tars, mineral oils, asphalts, or residues from destructive hydrogenation by impregnating granular porous materials such as pumice, slag, or coke with these products and passing the impregnated material quickly through a chamber maintained at red heat and quickly separating and cooling the resulting gas obtained in the manner described in the parent Specification. The carbon deposited on the porous material may be gasified in the manner described in Specification 214,544, (Class 55 (i), Coking &c.], and the gases employed for heating the reaction chamber. Slag impregnated with tar is fed from a hopper F by a conveyer B into a Cowper stove heated by a hot blast from a conduit A. Gases are drawn off through an outlet D and cooled for recovery of the benzines &c. An inert gas is blown by a fan E into the hopper F to prevent hot gases from the chamber below causing the pieces of material to stick together. These pieces may also be prevented from sticking together by dusting with ash or other powder. If the residues contain larger quantities of solid carbonaceous constituents they may be briquetted and passed in this form through the heating chamber. An alternative heating chamber comprising an externally heated nickel-chromium-iron tube through which the material falls, or an inclined revolving tube furnace may be used.

Title: Improvements in or relating to classifiers
IPC: B07B1/28
Filed: 1961-07-21
Abstract: 931,088. Sifting or screening apparatus. F. K. MOGENSEN. July 21, 1961 [July 25, 1960], No. 26600/61. Class 117. A screen classifier of the " sizer " type, i.e. the type where the mesh size of a screen is larger than the grain-size of the particles fed to said screen, comprises a group of screens arranged one above the other and each sloping downwardly in its forward direction from the feeding end of the classifier, particularly in which at least one screen slopes more steeply than the screen nearest above, characterized in that an impervious body is spaced vertically below the uppermost portion of at least one screen and is arranged to collect particles which have passed through said portion and feed them to the feeding end of the screen next below said screen. The " sizer as shown comprises impervious plates 22a to 22e secured to side plates 11 underneath such as screens 35a to 35c. The screens such as 35a to 35c are supported by front bars 31, intermediate bars 32 and stretching bars 33 having tension adjusting bolts 34 movable in sleeves 24 and are stretched between nose ribs 36, 37 on bars 31, 33. A vibrator 41 is provided and the sizer is suspended from springs 39. All the screens have the same mesh size. In operation, particles of different sizes are fed to screens via feeder plate 21. The smaller particles will pass directly through the screens while the coarser particles will impinge against the screens more frequently. and be reflected to pass through a lower level on the same screen so providing a separation according to size. It is stated that due to the inclination and the small distance between the screens at their uppermost portions, coarse particles falling on a screen from a higher screen tend to rebound in a rearward direction and pass through a mesh opening in the upper area of the screen so that after passing through the " sizer " the finest particles will be polluted with coarse particles. The impervious plate is said to prevent this by throwing all particles falling on it to lower areas of the screen below it. Specification 670,017 and U.S.A. Specification 2,853,191 are referred to.

Abstract: 270,309. Reisser, A., and Reder, R., (trading as Ing. Reisser & Reder). Nov. 20, 1924, [Convention date]. Multiplying and dividing apparatus. - A camdisc and pin-wheel machine is provided with two totalizing-counters I, II and the direction of rotation of one may be the same as or opposite to that of the other according to the position of a finger-plate 118. The two counters are situated apart a suffiicient distance to prevent the simultaneous engagement of the pins 4 with the intermediate pinions transmitting the actuation to the counters. In the case of the upper counter (I) the drive may proceed through and pinion 113 or through two pinions 130, 131, the latter being on shafts carried by a plate 126 secured to a centrally-pivoted lever 119 connected at its other end to the shaft 117 supporting the pinions 113. The finger-plate 118 is also attached to this shaft and by moving the plate to the right or left the shafts 117, 128, 129 are displaced axially to throw pinions 113 or pinions 130, 131 into the plane of the pins 4. By placing the finger-plate in the mid position the counter I may be entirely put out of action. Transfer - mechanism. - Each counter has a parallel shaft 136 or 136<1>, Fig. 9, on which are slidably mounted transfer-effecting discs 135 each possessing two teeth arranged at progressively decreasing distances apart. At transfer the lateral projection on the numeral wheel slides the corresponding transfer disc to the left to enter the plane of the next higher wheel, the disc being temporarily retained in displaced position by a spring-controlled pawl engaging a part circular groove in the boss of the disc. Before actuation of the counter commences, one of two groups of teeth 143<1> on a disc 142<1> secured to the bairel shaft rotates the transfer shaft through 180‹ and after actuation has ceased the shaft is rotated through the other 180‹ to cause any of the displaced discs 135 to effect transfer. The transfer shaft is driven by the disc 142' through alternative trains of gear wheels (one of which, namely, 145, 146, 147 is shown in Fig. 9) carried by the finger-plate 118 so as to control the direction of rotation of the shaft in accordance with that of the counter.

Abstract: 1,222,446. Cathode-ray storage tubes; photoconductive targets. WESTERN ELECTRIC CO. Inc. 7 June, 1968 [12 June, 1967], No. 27136/68. Headings HID and HlK. In a cathode-ray storage tube comprising a diode array target as in Specification 1,222,445, the image to be stored is read into the target by electrons having sufficient energy for each to produce a plurality of charge carriers. Holes produced in the target substrate then diffuse to the reverse-biased diodes to partially discharge the barrier regions. In a camera tube with an image-orthicon type arrangement (Fig. 1), the side of the target facing the image section is covered by a silicon dioxide insulating layer (19) and a transparent field-effect electrode (18) which serve to inhibit electron-hole recombination in the vicinity of the injection of the highenergy electrons. The field-effect electrode (18) may be pulsed, positively or negatively, to operate as an electronic shutter. In a scan converter (Fig. 2), with a similar target structure the reading electron beam is scanned at a slower rate than the high-energy writing electron beam. In the scan converter tube shown in which the reading beam in section 63 is scanned at a faster rate than the writing beam in section 92, the target structure 61 including N-type silicon substrate 64, diode P-regions 65, and an insulating covering layer 66 has on the rear side a heterojunction formed by the epitaxial deposition of a layer 68 of N-type germanium. The lattice defects in the vicinity of the heterojunction serve to trap the holes for a period as long as the scanning period of the writing beam while a continuing diffusion of the holes to the diode array allows repetitive read-out by the reading beam. The tube may be operated as a random access memory.
