IPC: C07C51/235
Filed: 1964-01-21
Abstract: Monocarboxylic acids, adipic acid and epsilon-caprolactone are made by co-oxidizing cyclohexanol and an aldehyde in the liquid phase with a gas containing molecular oxygen in the absence or presence of a catalyst comprising at least one transition metal compound in an amount of not more than 0.01% by weight metal compound based on cyclohexanol and under such conditions that the molar ratio of aldehyde to cyclohexanol in the reaction mixture at any instant does not exceed 1 : 10. Specified aldehydes are acetaldehyde, propionaldehyde, n- and iso-butyraldehyde, adipaldehyde, benzaldehyde and tolualdehydes. Up to 4 mol aldehyde per mol hexanol may be used, but the aldehyde is added gradually to the cyclohexanol to maintain the low concentration of aldehyde in the reaction mixture. It is preferred to operate at 45-135 DEG  C. and to use a catalyst comprising a Co, Mn, Ni, V, Cr, Ti or Ru carboxylate.  In the examples some glutaric and succinic acid and cyclohexanone are obtained as by-products.

Abstract: 945,610. Velocity-modulated beam tubes. VARIAN ASSOCIATES. Jan. 26, 1960 [Feb. 16, 1959], No. 2849/60. Heading H1D. A velocity-modulated charged particle discharge device comprises means for forming a beam of charged particles, means for accelerating the beam to an energy of 1 m.e.v., and means including poles spaced lengthwise of the beam for producing dipolar magnetic fields directed transversely of and through the path of the beam, the direction of the transverse fields alternating along the length of the beam in such a manner as to cause the charged particles to undulate in planes transverse to the direction of the transverse fields and about the mean direction of the beam and the fields between the lengthwise-spaced poles operating upon the undulating particles to exert a focusing action upon the beam. The magnetic focusing field, which has the form shown in Fig. 3, is produced by annular ferrite permanent magnets 9, 12, Fig. 1, and annular polepieces 11, 13 or the inner structure can be a corrugated polepiece with induced poles, Fig. 5 (not shown), or an electromagnet structure with coils arranged in the recesses of two annular concentric corrugated polepieces, Fig. 7 (not shown), or a single smooth cylindrical magnetic polepiece surrounds a system of permanent magnets and polepieces, Fig. 8 (not shown). The annular yokes 14, 16 of Fig. 1, can be dispensed with, Fig. 9 (not shown). The electron beam is annular. A radial electrostatic focusing field may supplement the magnetic field, Figs. 5, 8 (not shown).

Title: Fluid proportioner
IPC: G05D11/13
Filed: 1952-02-04
Abstract: 701,764. Fluid proportioning apparatus.. BOWSER, Inc. Feb. 4, 1952 [Feb. 13, 1951], No. 2929/52. Class 86 Apparatus for proportioning at least two fluids in flow includes a meter for each fluid, means for adding together the speeds of the meters, a speed change mechanism associated with each meter and driven by the adding means, the speed total of the outputs of the speed change mechanisms being equal to the speed total of the meters, and their individual outputs bearing a speed ratio equal to the required fluid proportion ratio, and means for altering the rate of flow of a fluid in response to a difference between the speed of the corresponding meter and the speed at the output of the associated speed change mechanism. In the arrangement shown.. liquids in supply lines 15 are discharged in predetermined proportions into a manifold 21 by means of electrically powered pumps 13, the rates of flow of the liquids being controlled by valves 12 which are automatically adjusted if the rates of flow of the liquids, as measured by flow meters 9, depart from the required ratio. The output shaft of each meter 9 is coupled to a differential gear mechanism 27, the differential gearing mechanisms being coupled together by shafts 35, 35<SP>1</SP>, whereby a final shaft 35" runs at a speed equal to the sum of the speeds of the meter shafts 23. The rotation of the shaft 35<SP>11</SP> is transmitted by a unity ratio chain drive 41 to a shaft 43 to which are coupled speed change mechanisms 45, each of which includes an adjustable speed change gear and a differential mechanism which enable the speed of rotation of the shaft 43 to be divided in a desired proportion, between output shafts 47 of the devices 45, the selected ratio, being the ratio desired between the component liquids supplied over the lines 15. Each shaft 47 is axially aligned with and rotates in the same direction as a shaft 24 of one of the differential mechanisms 27, which shaft 24 is driven at the speed of the corresponding- meter shaft 23. Each shaft 24 drives a nut 29 which is in screw-threaded engagement with the shaft 47, the arrangement being, such that a difference in speed between any pair of shafts 24, 47 causes an axial displacement of the nut 29 which is transmitted to the corresponding valve 12 in a direction such that the change in rate of flow of liquid as measured by the corresponding meter 9, tends to restore the equilibrium of the nut 29. The resulting change in the speed of this meter causes the speed of the shaft 43 to slightly change thus causing a corresponding change in the speed of the shafts 47 whereby an adjustment of the valves 12 in the other lines 15 is secured, the overall effect serving to maintain the fluids in the lines 15 in the predetermined proportions. Excessive movement of the nuts 29 in either direction operates switch means to open the circuit supplying electric power to the pump motors 17. The Specification describes in detail the differential mechanisms 27 and the speed change mechanisms 45.

Abstract: 457,425. Water-tube steam generators. SCHMIDT, M., 189, Corbacherstrasse, Cassel, Germany. Jan. 31, 1936, No. 3059. Convention date, Jan. 31, 1935. [Classes 123 (ii) and 123 (iii)] In boilers formed by multi-threaded helical coils arranged as the combustion chamber jacket, the connections between the tubes and upper and lower header rings are made over sections of tube running in the longitudinal direction of the header rings, the points of connection being distributed over the length of the rings. The furnace wall of a single-draught boiler is formed of six coils 5 each with a straight downcomer 6 and connected to lower and upper collector rings 7, 8 at positions 9, 10 uniformly distributed over the respective rings. Transfer ducts such as inclined slits 13 are provided along the juxtaposed walls of header and tube through which steam passes into the upper ring and thence to a superheater 15, water returning through the downcomer. Feedwater from an inlet 14 is introduced from the lower ring into the coils through similar slits. In one modification an annular combustion space round a charging hopper is lined by an inner threethreaded coil with seven convolutions and an outer eight-threaded coil with three convolutions, the tubes in the upper part of which are spaced apart to provide a gas exit. The upper headers are connected together and to the steam space of a feedwater reservoir from which supply tubes lead to the lower headers. Superheater and feedwater heater coils are arranged in a narrowed annular space above the combustion chamber. Another construction provides two downcomers only between the headers and a horizontal partition in the upper header with perforations at points beyond the delivery of the water-tubes in the direction of flow, the upper part of the header ring being connected to a reservoir or superheater. Or steam separation may be avoided in the upper header and downcomers directly from it dispensed with. Another embodiment includes additional watertubes comprising upriser portions leading to coils distributed over the flue, the tubes being connected to upper and lower collector rings and each having a downcomer to form a circulation unit.
