Abstract: 391,374. Indicating temperature distributions. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main. Germany. Oct. 25, 1932, No. 29868. Convention date, Feb. 8. [Class 97 (iii).] Heat rays from a hot body, which is not luminous or only slightly luminous, are projected on an excited luminous screen, the luminescence of the latter being more or less extinguished where the heat rays impinge, thus giving an indication of the temperature distribution. The luminous screen may comprise a surface coated with luminous paint, and is excited by exposure to blue or ultraviolet light. A strong lens may be used to project the heat rays thereon. A photographic reproduction of the screen may be made, thus producing a record of the temperature distribution.

Oct. 18, 1938, No. 30080. [Class 32] [Also in Group XXVIII] In the destructive hydrogenation of distillable carbonaceous materials containing solid matter in dispersion with hydrogen or gases containing free hydrogen under a pressure of at least 50 atmospheres and at a temperature above 300‹ C., a tube preheater is employed having return bends provided with internal parts in the form of a scoop constructed or coated with a corrosion resistant material having a Brinell hardness of more than 400. Thus the scoop-like member may be constructed of special cast alloys having a high content of chromium or may be coated with high melting enamels. Examples of alloys are given. As shown, the return bend A is provided with an interchangeable scoop-like member B, preferably positioned about the middle of the passageway, as shown in Fig. 1.

Abstract: 470,950. Carbonizing - apparatus. DIDIER-WERKE AKT.-GES. Nov. 5, 1936, No. 30128. Convention date, March 3. [Class 55 (i)] In continuous vertical retorts wherein the gases are withdrawn from the retort in an upward direction through an internal offtake, the offtake is formed in a hollow wall extending between the two end walls or the two side walls of the retort respectively, the offtake being in contact on two opposite sides with the fuel in the retort. More than one offtake may be used and they preferably extend from the top of the retort into the lower half thereof. In a retort 3 provided with a single offtake 5, the latter comprises parallel walls extending to the end walls of the retort, and above the latter the offtake continues through a preheating chamber 2. The fuel is thus preheated internally both within the retort and before it reaches the same. The preheater may also be externally heated. In a modification, the offtakes comprise built-in tubes 9, 9a, Fig. 2, extending to the side walls of the retort. The cross-section of the offtake is preferably greater than that of the fuel space formed between the walls of the offtake and the heating walls 8, 8a of the retort. Steam or other gases such as water gas may be introduced into the carbonization gases before withdrawal through the offtake.

[Also in Division G3] To reduce inertia in a magnetic tape or other web transport system, the tape has two single loops at 7, 8 on either side of the read/write head 20, the size of the loops being maintained by the application of suction to the tape at capstans 15 or 16, 26 or 27 which continuously rotate at a slightly greater speed than main capstans 18 or 29 according to whether the loop interrupts light to photo-cells 33, 34 and 37, 38, and also two multiple loops in bins 3, 4, the level of tape in each bin being controlled by the switching on or off of reel motors in response to further photo-cells. These photocells are arranged in pairs; consider bin 3 filling from the top, the reel 22 is started when pair 48, 52 are obscured and stopped when 49, 53 are illuminated, and when tape is drawn from the top reel 22 is started (in the opposite direction) when 50, 54 are illuminated and stopped when 49, 53 are obscured. Further photo-cells 41, 47, 51 and 42, 55, 59 shut down the system if the others are overrun. The photo-cells operate through bi-stable circuits (Fig. 7, not shown); for the reel motors these actuate relays controlling electromagnetic clutches and brakes, and the energization of control windings of magnetic amplifiers (68, 86, Fig. 6, not shown) in series with diodes in the armature circuits of the motors whose shunt fields are energized via reversing relay contacts. Reel speed is controlled by rheostats (82, 89) in series with the control windings; they comprise resistors (139, Fig. 3, not shown) which are sequentially short circuited by reed contact units (134 and Fig. 5, not shown) actuated by individual magnets upon removal of an arcuate screen (129) geared to a spring arm (97) which detects the diameter of tape on the reel.

The apparatus may be filled with the solvent, which is agitated until the residues are dissolved. Alternatively, the solvent may be streamed over the residue-bearing surfaces of the apparatus. Alternatively, the solvent may be discharged from spray heads located in the upper regions of the apparatus, dissolved residue and dislodged particles of residue then collecting with the solvent in the lower part of the apparatus, where the dislodged particles dissolve. The collected residue-containing solvent may then be pumped back to the spray heads. Recirculation continues until all the residue is dissolved. The apparatus may be heated during the cleaning time. The temperature of the solvent is preferably between 80 and 125 C. and ideally between 90 and 105 C. The volume of solvent used is at least 10%, e.g. 25%, of the volume of the apparatus. After treatment with the solvent, the apparatus may be sprayed with water. The solvent is used until the dissolved residues reach a certain concentration; the solvent is then regenerated. Regenerating the solvent.-In a first stage evaporator, the solvent and water are boiled off. The remaining viscous solution is treated in a second stage evaporator, which is mechanically aided to permit the removal of further amounts of solvent and water. The water is then separated from the solvent in a fractionating column. Before the evaporating stages, the residues may be precipitated by adding the residue-containing solution to 20-50% by volume of water.
