Title: Improvements in and relating to polyacrylonitrile solutions
Inventor: MACKENZIE HECTOR DOUGLAS
IPC: C08F283/00
Filed: 1959-06-25
Abstract: In a modification of the process of the parent Specification acrylonitrile polymers containing at least 80% acrylonitrile are prepared by dissolving the acrylonitrile with or without other monomers such as styrene, methyl acrylate, itaconic acid, vinyl acetate or vinyl pyridine in a concentrated aqueous or acqueous/alcoholic solution of an inorganic thiocyanate and polymerizing the monomer or monomers in solution at a pH of 4 to 8 in the presence of a non-oxidising polymerization catalyst forming free radicals which is an azo compound and in the presence of a cuprous salt and a reducing agent which is inert to the azo compound under the polymerization conditions. The reducing agent may be thiourea dioxide and the cuprous salt may be added as such, e.g. cuprous thiocyanate, or as a cupric salt, e.g. copper sulphate.  The effect of the cuprous salt is to reduce the molecular weight of the polymer produced.  The azo catalyst may be azobis-isobutyronitrile and ammonia and sodium hydroxide may be added to the polymerization solution to adjust the pH value. Fibres may be spun from the polymer solutions and ribbons and films may also be produced. Specifications 824,361 and 864,096 are referred to.

Title: Method of reconditioning toxic effluent and plant for carrying out the method
IPC: B01D1/14
Filed: 1976-05-27
Abstract: After introducing the toxic wastewaters (A) into the plant, these are preheated (4), concentrated by evaporation (5) and spray-dried (6) in the hot exhaust gas stream of a combustion plant (1). The exhaust gas stream loaded with solid waste materials is purified in the dry (7) and wet (8) state and discharged (24) into the atmosphere. Particularly toxic wastewaters (A1) are detoxified (21) prior to the introduction (A). The dry matter (D) separated off in the solid separator (7) can be landfilled and the cooled condensate (17, 20) can be discharged into an outfall (22). In the case of multiple-stage evaporation (5), the vapours are used for heating downstream evaporator stages (10), while the first evaporator stage (9) is heated by the hot exhaust gases from the waste-heat boiler (2) of the combustion plant (1). The process is suitable in particular for treating wastewaters from thermal power stations, refuse incineration plants and works in the electrolytic sector and chemistry. <IMAGE>

[Classes 97 (i) and 98 (ii)] In optical-projection apparatus, the light is reflected by the image without scattering and is projected by optical means on to a screen. As shown in Fig. 1, light from the source 15 reflected by the mirror 16 is reflected by the image 20 on to a prism 25 having a semi-transparent reflecting cemented surface 26 situated at the focus 18 of the rays reflected by the image 20. The rays reflected by the surface 26 are projected on to a screen 30 by an objective 28. The surface of the prism facing the source of light 15 may be spherical. A planoconvex lens inclined at 45‹ to the plane of the image and in which the plane side, which faces the image, is semi-transparent, may replace the prism. A glass plate having the side facing the image semitransparent may be employed in conjunction with a convex lens between the plate and the light source and having its focus behind the image. The reflecting surface may be so placed that the focus 18 falls in the objective 28. In a further modification the reflecting surface may reflect the light on to the image, which is parallel to the original light rays, and two lens systems are arranged on opposite sides of the reflecting surface. Fig. 7 shows a stereoscopic camera with two lenses 44, 45 producing images on both sides of the film 48 by means of the two mirrors 50, 51.

Title: Apparatus for pumping liquids from containers
IPC: F04D9/00
Filed: 1961-06-20
Abstract: 906,580. Centrifugal pumps. CIBA Ltd. June 20, 1961 [June 23, 1960], No. 22283/61. Class 110 (1). Apparatus for pumping a liquid from a container comprises a vessel within which is enclosed a centrifugal pump, the suction side of which communicates with the interior of the vessel, a pressure pipe extending upwardly from the vessel and communicating with the pressure side of the pump, a suction pipe which opens in the vessel near the bottom thereof, has an elbow bend above the top of the vessel and extends downwardly for delivering liquid from a container to the vessel, and a narrow passage affording communication between the elbow bend and the portion of the pressure pipe extending upwardly from the level of the elbow bend. The centrifugal pump depends from a cover-plate 12 for a container (not shown) for the liquid to be pumped. A motor (not shown) mounted above the cover-plate 12 drives the pump through a shaft 34 passing through a tube 36 which extends beyond the highest level of the liquid in the container. The centrifugal pump is immersed in a vessel 18 which communicates with the interior of the container through a suction pipe 20 having an extension (not shown) which terminates close to the bottom of the container. Initially, the liquid in the suction pipe 20 and a pressure pipe 24 is at the level 52 and the vessel 18 is full. When the pump is started, it draws liquid from the vessel 18 through an inlet 33 and delivers it to the pressure pipe 24. The resultant reduction of pressure at the top of the vessel 18 causes liquid to be drawn out of the container through the suction pipe 20. When this liquid has reached the elbow bend 48, priming of the pump is complete and the liquid in the vessel 18 has fallen to the level 54. Since the outlet opening 44 of the suction pipe 20 is below this level (and advantageously at a higher level than the pump inlet 33), the formation of foam or bubbles due to entrainment of air is prevented. To accelerate the priming, the suction pipe 20 may communicate with the upper part of the vessel 18 through a narrow bore. When the pump is stopped, the liquid in the pressure pipe 24 runs back through the vessel 18 and the suction pipe 20 into the container until it reaches the level of an anti-siphoning conduit 50. Air then passes through the conduit 50 to the suction pipe 20 to break the siphon and the liquid level is stabilized at 52. Specification 864,620 is referred to.

In a railway cab-signalling system for the continuous indication of the condition of the track signals ahead of a train periodic signalling current pulses having the form of high current peaks e.g. of the order of 10 amperes with a constant short duration of the order of one millisecond, and of selected polarities and variable time intervals are fed to the track rails 1, 2 as from a generator 10 and received and transmitted to the cab receiving apparatus by pick-up devices 6, 7 inductively coupled with the rails 1, 2 and interconnected so as to eliminate the effects of traction return currents and to prevent the transmission of pulse signals from affecting the receiving apparatus in more than one train or vehicle V, the receiving apparatus 8 discriminating between the polarities and between the intervals of the pulses and comprising a selective integrating receiver e.g. as used in radio technique, arranged for timedelayed cumulative operation so as to respond only to a regular succession of the periodical pulses, but not to effects of a transitory nature or of short duration, the output of the receiver being fed to control a train control apparatus or a visual or aural indication device 8a e.g. containing red, green and yellow lamps 18. As shown, one terminal of the pulse generator is connected directly to one insulated rail section 2 at the exit end of the section, while the other terminal is connected to the mid-point of an impedance Z1; Z2 connected across the rails at the entrance end of the section. The impedances may be inductances or capacitances. The impedances Z1, Z2 and Z3 at the ends of the section may be provided by windings of the inductive connections e.g. input and output transformers of a track circuit comprising one insulated rail or where traction currents return through one continuous rail in a direct current track circuit, or by the inductances of bonded rails in which the traction current returns, through both insulated sectioned rails. Where pulses of opposite polarities are used the generator 11, Fig. 2, has two output circuits with three terminals a, b, c, the terminals a, b of opposite polarity being connected to respective rails 1, 2 at the exit of the section of the third terminal c to the mid point of the inductances Z1, Z2 across the rails at the entrance to the section.
