Title: Improvements in the continuous chlorination and chlorosulphonation of ethylene polymers
IPC: C08F8/20
Filed: 1964-12-16
Abstract: A process for the continuous chlorination or chlorosulphonation of ethylene polymers containing 85-100% by weight of units derived from ethylene, comprises (1) mixing chlorine, and optionally also sulphur dioxide, uniformly with a solution in an inert solvent of the ethylene polymer under a pressure sufficient to maintain all the components in the liquid phase, (2) before more than 1/5 of the chlorine has combined with the ethylene polymer passing the mixture through a reaction zone maintained at a temperature of 90 DEG  to 250 DEG  C. under a pressure sufficient to maintain all the components in the liquid phase, and (3) arresting the reaction before all the chlorine has reacted. The ethylene polymers may be homopolymers or copolymers with comonomers such as propylene, butene-1, octene-1, vinyl acetate, and methacrylic acid.  The preferred solvent is trichlorofluoromethane the flashing off of which, at the end of stage (2), terminates the reaction and leaves a solvent-free product. Where carbon tetrachloride is used as the solvent, that remaining after flashing is removed by precipitating the reaction product therefrom with methanol and subsequently washing with acetone.  Reaction inhibitors such as iodine, oxygen, or 1,1-diphenyl-2-picryl hydrazine may be added before or during the mixing stage (1), and catalysts for the reaction stage (2), such as peroxides, persalts, and azo catalysts, may be added to the mixture after the mixing stage (1) and before the mixture enters the reaction zone.  Suitable apparatus is described.  Compositions are disclosed comprising the modified polymers of the invention with litharge, furnace carbon black, clay, microcrystalline paraffin wax, and the usual stabilizers and curing agents.

Title: Improvements relating to monitoring systems for shaft furnaces
IPC: C21B7/24
Filed: 1965-12-02
Abstract: 1,119,165. Monitoring charge movement in shaft furnaces. GESELLSCHAFT ZUR FORDERUNG DER EISENHUTTENTECHNIK m.b.H. 2 Dec., 1965 [2 Dec., 1964], No. 51276/65. Heading F4B. An arrangement for monitoring the movement of the charge in a shaft furnace comprises at least one pair of radio-active sensors arranged one above the other to emit signals when the charge falls below the level of each sensor, the signals being fed to devices which produce an indication proportional to the rate of descent of the charge. The signals from the sensors may be used to start, stop or restart integrators forming the time integral of the blast rate, which in normal operation is proportional to the rate of charge descent. If this integral exceeds the appropriate value before the upper sensor emits its signal, the charge has bridged above it, and a warning light is energized. Similarly, a warning is given if the charge bridges between the upper and lower sensors. When the integral reaches a set value after being returned to zero at the signal from the lower sensor, a charge signal is energized or an automatic charging process initiated. Several pairs of sensors may be spaced round the furnace to eliminate errors due to a slanting charge surface.

Abstract: 1324015 Transport flasks KERNFORSCHUNG mbH GES FUER 2 Nov 1970 [3 Nov 1969] 51975/70 Heading B4Q A flask for transporting irradiated fuel elements 7 immersed in liquid metal coolant 8, e.g. Nak, in a receptacle 5 of neutron-absorbing material, e.g. boron or cadmium alloy, comprises a body 1 constituting both a radiation screen and a pressure-resistant container, the open end of the cavity within the body being sealed by an inner cover 3 and outer cover 4. The massive cover 3 is loosely mounted for limited axial movement within the body 1 and has cavities 24 for receiving the upper ends of the fuel elements. A seal between the body 1 and cover 3 permitting this axial movement comprises an annular member 10 of serpentine cross-section, the upper and lower ends of this member being secured to rings 11, 12, these rings being respectively sealed to the cover 3 and body 1 by annular metal packings 13, 14 and bolts 15, 16. The cover 4 is secured by nuts 23 screwed on to necked-down bolts 18 making a screw connection at their bottom ends with bores 19 in the body 1, the bolts being surrounded by lead sleeves 21. Should the flask be subjected to a high deceleration due to a fall, the mass of the fuel elements 7 and coolant 8 acting on the cover 3 may cause the cover 3 to move until it abuts the cover 4; however, the seal is maintained by member 10 and packings 13, 14. Further, this action does not cause breakage of the bolts 18 since they may elastically or plastically extend. A steel jacket 27 around the body 1 forms an annular space 28 through which air coolant may be pumped via pipes 27a, 27b.

Title: Electronic display systems utilizing a multifunction storage tube
IPC: G09G1/26
Filed: 1970-11-02
Abstract: 1335371 Alphanumeric display PRINCETON ELECTRONIC PRODUCTS Inc 2 Nov 1970 [13 Nov 1969] 52040/70 Heading H4F [Also in Division H1] Apparatus for generating bright-up signals for the display of alphanumeric characters on a cathode-ray tube utilizes an electrostatic storage tube whose target area is additionally provided with a zone on which a set of characters is formed as a physical pattern, so that these characters can be scanned and the resulting electrical signals stored and then used to write the characters on appropriate storage areas for subsequent read-out. Fig. 3 illustrates the layout of the tube target which comprises a doped silicon substrate with a pattern of insulating silicon dioxide elements thereon forming a storage mosaic area 35 and a character area 37, horizontal and vertical indicial elements 41, 42 also being provided for spot positioning control. The writing of a character into the storage area is effected by first obtaining its position in 37 relative to the indicia from a store; scanning the beam horizontally along the indicia 41 until a counter receiving tube output pulses registers the desired position count, and storing the deflection signal at this point; repeating for a vertical scan along 42; positioning the beam at the desired character using the stored deflection signals and scanning the character in raster fashion to derive video output signals which are stored; repeating the scanning of indicia to determine deflection signals corresponding to the address in 35 at which writing of the character is desired; and positioning the beam and writing the character using the alreadystored bright-up signals. After this operation has been repeated to complete the desired character display format, the pattern set up in the electrostatic storage area is scanned and the bright-up signals read out for display on a television-type raster-scanned C.R.T. In order to reduce the data storage capacity needed outside the tube, the data derived from the scan of a character in area 37 may be transferred to 35 column-by-column, i.e. one 9-bit column of a 9 x 7 bit representation is scanned and stored and the beam re-positioned to write this column in 35 before returning to scan the next column. A modified indicia system is described (Fig. 5, not shown) in which positions are recorded in binary notation with a separate horizontal (and vertical) row of indicia for each binary order, thus enabling speeding up of the positioning; in another modification the indicia are stored in the storage area proper and recognized as "infra-black" type signals on scanning.

Abstract: 1325753 Photo-electric absorption analysis BAXTER LABORATORIES Inc 5 Nov 1970 [6 Nov 1969(2)] 52596/70 Heading G1A In an apparatus for testing the radiation absorption characteristics of a test material 222, radiation passing through the material in one direction is redirected through the material by a retro-reflector 226 and is finally directed to a photo-cell 232 via a beam splitter 220. As shown, a moving photographic film 224 is scanned, and this scanning may also be achieved by having a rotating mirror drum, Fig. 8 (not shown) or oscillating mirror in the light path to a stationary film. The beam splitter 220 and film 222 may be inclined to one another, Fig. 7 (not shown) so that light specularly reflected from the film surface is not received by the photo-cell. The light need not be scanned across the test object, which may be a fluid in a cuvette. For such fluid testing, the cuvette may be one of a series which are moved up and down or rotated during inspection, and in this application the retro-reflector is preferably curved, Fig. 5 (not shown).
