Title: Improvements in the manufacture and production of organic acids and their salts
IPC: C07C51/487
Filed: 1929-02-08
Abstract: 324,538. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Feb. 8, 1929. Organic acids are recovered from the oxidation products of high molecular aliphatic compounds such as paraffin wax, montan wax or gas oil by saponifying the oxidation products, treating the aqueous soap solution with a water-insoluble organic extraction agent such as ligroin, benzine or ethers, and adding a mineral acid to the extract, the emulsion separating from the extract being decomposed by adding a low molecular aliphatic alcohol such as methyl alcohol, after which the layers formed are separated. The greater part of the unsaponifiable material may be separated before extaction by settling, centrifuging or the like. If a strong saponifying agent is used, e.g. an aqueous caustic alkali solution of more than 25 per cent strength, the alcohol may be added before the extracting agent. In an example oxidized paraffin wax containing 20 per cent unsaponifiable material is saponified with the necessary quantity of caustic soda solution. The soap solution is diluted ith water and shaken with benzine (B.P. 70‹-100‹ C.) at 60‹ C. From the emulsion thus formed, clear soap solution is separated by centrifuging. The remaining emulsion is shaken with methyl alcohol, and forms two layers, of which the lower is clear soap solution, the upper contains the benzine, a part of the methyl alcohol, and the unsaponified material in solution. Fatty acids are separated from the soap solution by means of a mineral acid. In another example oxidized paraffin wax containing 35 per cent unsaponified matter is heated to boiling with a 50 per cent caustic soda solution, until complete saponification occurs, the mass is then left standing whereby two layers are formed. The lower layer containing saponified matter is separated and diluted with water. The solution is incorporated with ethyl alcohol and benzine, and stirred for ¥ hour at 66‹ C. After standing, the alcoholic solution is separated and the aqueous solution extracted again with which benzine is then distilled off.

Title: Improvements in sealing devices for crank pin bearings
IPC: F16J15/44
Filed: 1939-02-10
Abstract: 528,175. Sealing devices for crank pins. AKTIEBOLAGET BOLINDER - MUNKTELL. Feb. 10, 1939, No. 4449. Convention date, Feb. 11, 1938. [Class 122 (v)] A sealing device for the bearings of crank pins having a diameter less than the length of adjacent crank webs comprises members which are rigid radially and contact the outer of the relatively movable bearing elements under an outwardly acting initial pressure, and which are formed with axially self-adjustable sealing surfaces sliding against the other bearing element, said members being assembled on the crank pin by resilient deformation and being disposed within the outer peripheral boundaries of the crank webs. In the form shown a sealing rung 16 is secured to the crank-web 10a or crank pin 15 as by means of a tapered sleeve 17 inserted between the crank pin 15 and the ring, or otherwise, and a projecting lip on the end of the crank web 10a may fit over its outer surface. The ring 16 may be formed from the material of the pin 15, or of parts welded together, or of half-rings held in place by a closed ring shrunk on to them, the closed ring being formed from the material of the pin. Two resilient split rings 20, maintained with their open ends spaced circumferentially by a plate riveted to one ring engaging a recess at the ends of the other ring, are placed in a circumferential recess 19 in the ring member 16 and rotate with the race 14 of the connecting- rod but are capable of axial movement along the surface 21 thereof under the action of the lubricant pressure so as to cause a projecting surface 23 to bear against one side of recess 19 and form an oil seal. The surface 23 or the surface 21 may be eccentric relatively to the crank pin so as to cause radial movement of the surface 23 relatively to the member 16, and the surface 23 may be slightly undulating. The lubricant pressure may be assisted by springs within the recess 19.

Title: Speed measuring device
Inventor: ROBBINS LEO
IPC: G01P3/46
Filed: 1957-02-11
Abstract: 805,987. Voltage measurement. BALDWINLIMA-HAMILTON CORPORATION. Feb. 11, 1957, No. 4599/57. Class 37. [Also in Groups XIX and XXXVIII] The voltage output from a tacho-generator (not shown) is displayed on a valve voltmeter 50 through a circuit which compresses the higher part of the scale and gives the same order of accuracy over the whole range. The operation of the circuit depends on the fact that the generator output (connected via lines 32) varies in voltage and frequency simultaneously, both being proportional to the r.p.m. At low outputs C has a much higher impedance than R and the network has very little effect on the voltmeter reading. As the output increases C passes progressively more current and the meter begins to read low. When the impedance of C is much less than that of R the circuit C1R1 takes over as C1 begins to shunt R1, and at still higher outputs C2R2 becomes effective. Any number of such CR circuits may be added to extend the principle to still higher frequencies. Normal shunts R3 and R4 may also be included. The filters may contain inductive elements.

Filed: 1921-02-11
Abstract: 180,394. Bassler, E. M. Feb. 11, 1921. Endless-band conveyers; fibrous, granular, and plastic material carried on; air, controlling direction of flow of.-Relates to a drying process and apparatus in which hot air is passed in the opposite direction to material carried through a casing so constructed that the air passes repeatedly through the material, and consists in passing relatively cold air through the hot material before its discharge so as to cool the material and preheat the air before passing it through a heater to the casing. As shown, the apparatus comprises a drying-chamber B, Fig. 2, through which the material is passed by an enless-band conveyer C, the ends of which extend beyond those of the chamber and are exposed to the atmosphere, and a housing J, Fig. 6, located at the discharge end of the apparatus and containing the conveyer drive, fan, and air-heating apparatus. The housing communicates with the atmosphere through the enclosed space beneath the discharge end of the conveyer and the adjustable openings j. The drying-chamber is open at its admission end and closed at its discharge end by a roller 17, Fig. 4, which is mounted upon counterweighted arms 18 pivoted to the sides of the casing and which rests lightly upon the material on the conveyer. A canvas curtain 22 suspended from the shield 21 of the roller prevents air escaping from the discharge end of the chamber. In operation, the material is fed upon the conveyer and passed through the drying-chamber in the opposite direction to that of the air which is drawn by the fan H through the dried material upon the discharge end of the conveyer, thus cooling it, and passed through a heater I and and aperture i into the discharge end of the chamber. The chamber is provided with transverse partitions 24, 25, 26 of canvas so as to direct the air upwards and downwards through the material to the open end of the chamber. The conveyer is adjustable in length and is formed of endless chains mounted upon sprockets and connected by transverse bars for supporting the material. The conveyer chains are provided with rollers which are supported upon guides secured to the sides of the chamber.
