Title: Separation of crystals from solutions
Inventor: HANSEN GUENTER
IPC: C23F14/00
Filed: 1962-04-06
Abstract: In a process for depositing crystals from aqueous solutions using heat exchangers, the rate of alestration of heat from the solution is controlled and incrustation of the heat exchanger is prevented by measuring and regulating the temperature and/or feed rate of the solution and/or the temperature and/or feed rate of the coolant in such a way that the heat transfer is limited to a maximum within the range of 6000 to 15000 K Cals per hour per sq. metre of heat exchange surface, depending on the differential velocity between the solution and the heat exchange surface. The process may be controlled manually or automatically and may be used for aqueous solutions of organic or inorganic salts, e.g. alkali metal salts, NaNO3, or (NH4)2SO4, NH4Cl. Coolant is supplied to the heat exchanger at an elevated temperature during the first few minutes. If one medium is supplied at a constant rate and the temperature difference between the feed and discharge of this medium is increased or decreased, the feed rate of the other medium is decreased or increased respectively.  If one medium is supplied to the heat exchanger at constant rate and the temperature difference between the feed of the one medium and the discharge of the other medium is increased, the feed rate of the other medium is increased, and vice versa. If the solution and coolant are supplied at constant rates and the temperature difference between the feed and discharge of the solution is increased, the temperature of the coolant is raised, and vice versa.  If the solution is supplied to a heat exchanger at a constant rate and at a constant temperature and the discharge temperature of the solution is increased, the feed rate of the coolant is increased and vice versa, or if the coolant is supplied at a constant rate and a constant temperature and the discharge temperature of the coolant is increased, the feed rate of the solution is decreased, and vice versa. In batchwise operation the feed rate of the coolant is increased when the change in temperature of the solution measured at equal time intervals becomes smaller, and vice versa.  In an example, a solution of NaNO3 saturated at 44 DEG C. was cooled with water at 13 DEG  C. in a glass tube cooler at a heat exchange rate of 6900 K Cals per square metre per hour. Alternatively, a rotating cooling drum may be used.ALSO:In a process for depositing crystals from aqueous solutions using heat exchangers, the rate of abstraction of heat from the solution is controlled and incrustation of the heat exchanger is prevented by measuring and regulating the temeprature and/or the feed rate of solution and/or the coolant in such a way that the heat transfer is limited to a maximum within the range of 6000-15000 K Cals per hour per square metre of heat exchange surface, depending on the differential velocity between the solution and the heat exchange surface.

Title: Improvements in and relating to the solvent treatment of oils
IPC: C10G21/00
Filed: 1938-05-04
Abstract: 509,642. Selective solvent extraction of oils. STANDARD OIL DEVELOPMENT CO. May 4, 1938, No. 13371. Convention date, Aug. 3, 1937. [Class 91] In a process for the extraction of mineral oils, especially lubricating oils, with a selective solvent in a counter-current treating tower, the flow of solvent and oil is so regulated that the solvent-rich phase is the continuous phase, and the plane of separation of the two phases is maintained at a point near the top of the tower. The throughput is increased, since the oil droplets rise through the solvent which is of lower viscosity than the oil. For example. a treating tower is fed at the top with phenol cresylic acid, furfural, ##-dichlorethyl ether, nitrobenzene, or liquid sulphur dioxide, until it reaches a desired level near the top, whereupon there is admitted at the bottom a dewaxed oil. Phenol is thereby maintained as the continuous phase. A temperature of 110‹F. is maintained at the bottom of the tower, and 185‹F. at the top. Comparative figures for the raffinate and extract obtained when (a) the solvent phase (b) the oil phase is the continuous phase, show that the throughput for (a) is 2 to 3 times that of (b).

Title: Improvements relating to photographic cameras
IPC: G03B9/12
Filed: 1959-04-20
Abstract: 883,911. Camera shutters. OPTISCHE INDUSTRIE DE OUDE DELFT. N.V. April 20, 1959 [Oct. 30, 1958], No. 13400/59. Class 98(1). A photographic camera has a focal plane shutter comprising at least two coaxial, axially spaced, adjacent, opaque circular discs differentially rotatable in a common direction about a common axis perpendicular to the focal plane each disc having at least one radial aperture extending to the periphery of the disc the aperture(s) in one disc being narrower than those in the other. In the stereoscopic camera shown, one of two films is mounted on shafts 32, 33 so that it passes over sprocket rollers 34, 35; the other film is similarly mounted in a compartment 28. These films are advanced by the rollers which are driven at a constant selected speed by an electric motor 40 through an electromagnetic coupling 47 and a worm gear 49. To drive each film at a different speed a second electromagnetic coupling and worm gear may be provided. The spindle 33 of take-up spool 30 is rotated by shaft 50 through pulleys 53, 54 and crossed belt 55. The two shutter discs 26, 25 are mounted on coaxial shafts 39, 38 respectively and are driven at differential speeds by sprocket wheels co-operating with toothed belts 43, 42 driven by the motor 40. The width of the wider aperture in disc 26 depends on whether both image areas are exposed by the apertures in the same revolution in which case the aperture is very wide or whether only one area is exposured every x rotations when the aperture can be narrower. Each disc may be provided with a second aperture and a third apertured disc may be added to vary the frequency of the exposures. This shutter is also described when incorporated in an ordinary camera and in a miniature camera. When in the latter it is spring driven as shown in Fig. 8. The spring motor comprises a drum 83 rotatably mounted on a shaft 84 and controlled by a spring 87 which may be wound up by a knob on shaft 84. When the drum rotates it drives the shaft 109 to which one of the shutter discs is attached through gear-wheel 86, 106, 103, 108 and the other shutter disc mounted coaxial with the first is similarly rotated. When a button 101 is depressed the latch 96 on arm 97 moves downwards together with the projection 95 on the arm 96 which is moved away from a pin 93 on the drum. The drum then rotates clockwise until the pin 93 pushes the arm 97 to the right thereby freeing the arm 94 which is brought back to the position shown by a spring.
