Title: Process for the production of stabilized acrylonitrile polymers
Inventor: RUNGE JUERGEN
IPC: C08K5/3415
Filed: 1966-11-15
Abstract: 1,126,056. Stabilized acrylonitrile polymers. CHEMISCHE WERKE BUNA VEB. 15 Nov., 1966, No. 51076/66. Heading C3P. Polymers, or shaped bodies formed therefrom, comprising 20-100% by weight of units of acrylonitrile and 0-80% by weight of units of one or more comonomers are stabilized against thermal discolouration by incorporating therein, e.g. in an amount of 0À01-10% by weight of the polymer, a compound containing the radical once or twice in the molecule, preferably a maleimide or bis-maleimide of formula where A is a straight- or branched-chain alkylene residue, a mono- or poly-nuclear arylene residue or a divalent residue of a hetero-aromatic which is optionally substituted (in addition to the R substituent), or a group >C=O, > C = S, >SO, > SO 2 , or a residue alkylene-x-alkylene, residue alkylene-x-arylene or residue arylene-x-arylene, x being >NH, >C=O, alkylene, -S-, >C=S, -SO-, -SO 2 - or -O-; and R is an aliphatic, cycloaliphatic, aliphatic-aromatic, possibly substituted aromatic or hetero-aromatic residue, or hydrogen, halogen, cyano, nitro, amino or hydrocarbon radical-substituted amino; and where the group R-A- may be replaced by hydrogen. The stabilizer may be incorporated into the polymer as a solid or in solution, and where the polymer is shaped (e.g. into a film, foil or fibre) can be added before or after shaping. Stabilizers exemplified are maleic acid imide and its N-n-butyl, N-phenyl, N-pbromophenyl, N-o-tolyl, N-α-naphthyl and N- benzyl derivatives, and N,N<SP>1</SP>-p-phenylene-bismaleic acid imide. In examples these stabilizers are added to polyacrylonitrile, acrylonitrile - styrene - acrylic acid copolymer and acrylonitrile-vinyl acetate copolymer; the latter copolymer is in some cases admixed with stabilizer in dimethylformamide solution.

Abstract: 1417076 Toothed gearing SUWA SEIKOSHA KK and SHINSHU SEIKI KK 5 Nov 1973 [20 Nov 1972] 51193/73 Heading F2Q A mechanism for imparting oscillatory motion to a shaft 25 comprises a driving wheel 21 mounted on a shaft 20 and having a toothed portion 22, a cam portion 23 and a non-toothed portion 24 on its periphery, and a driven wheel 26 mounted on shaft 25 and having a toothed portion 26a and a non-toothed portion 27, the wheel 26 being urged to a rest position, in which a pin 31 on the wheel 26 engages a fixed stop 30, by a coiled torsion spring 28. Anti-clockwise rotation of driving wheel 21 from the rest position shown in Fig. 3 causes engagement of toothed portion 22 with toothed portion 26a and increased tension of the spring 28. The cam portion 23 then co-operates with the non- toothed portion 27 and prevents reverse rotation of gear 26 until the non-toothed portion 24 of wheel 21 arrives adjacent the driver wheel 26 when the wheel 26 is returned to its rest position under the influence of the spring 28. The mechanism is applied to a printing machine.

Title: Apparent altitude changes in camera visual system
IPC: G09B9/30
Filed: 1971-11-16
Abstract: 1310659 Television SINGER CO 16 Nov 1971 [4 Dec 1970] 53024/71 Heading H4F In a pilot trainer the view from the cockpit is simulated by means of a television camera viewing a model of terrain, e.g. a landing site with horizon 19, object C, Fig. 2a, and a television display reproducing the view, Fig. 2b. Changes in altitude of the aircraft can be simulated by actual movement of the camera only for camera heights above a certain minimum, e.g. below this, the camera, or an optical probe thereof, obstructs the model. For simulation of lower altitudes, the normal scanning raster of the camera 21, Fig. 2a, is vertically stretched (Fig. 2c) whilst leaving the raster of the display, Fig. 2d, unchanged. A simulated change in aircraft pitch is achieved by a shift in the centre of the camera raster. For the case of a change in altitude when the camera viewing axis is pitched down from the horizontal, i.e. the camera view and display are as shown at Fig. 2e and 2f, the arrangement of Fig. 4 is used. A sweep generator 31 feeds horizontal sweep signal H to the camera 35 and display 33. The vertical sweep signals, although fed directly to the display are also combined at 39 with a signal -f(#) representing the negative of a signal f(#) proportional to the change in pitch. This is equivalent to realigning the camera with the horizon. The lowering of altitude is then simulated by stretching the scan in multiplier 47 by a factor being the ratio of the actual altitude to the altitude to be simulated. The repitching of the lowered camera is then simulated by the removal of the negative shifting term -f(#) in adder 45 to give the actually used scan 21, Fig. 2i, and the simulated display, Fig. 2j. Rolling of the aircraft can also be simulated.

Apparatus for making fluted tubing comprises first and second fluting rolls 30, 32 disposed on opposite sides of the strip stock, means 38 for disengaging the rolls at predetermined intervals from the stock to leave sections of strip unfluted, a trimmer 40 for trimming the stock to a predetermined width, and a guiding mechanism for bringing opposite edges of the trimmed stock together to form a fluted tube having smooth sections at predetermined intervals. The guiding mechanism comprises breakdown rolls 50, cluster rolls 52 and forming rolls 54. The strip stock 10 is fed from an uncoiler 14 via an accumulator to drive rolls 20, 22. A guide roll 24 positions the strip horizontally before passage through the fluting rolls 30, 32. The strip is trimmed to a constant width by an edge trimmer 40 and the scrap is received on a scrap winder 42. The edges of the formed tube are seam-welded using welding apparatus 60 (e.g. high frequency induction, resistance welding, gas tungsten arc, gas metal arc). Weld pressure rolls 62 and inner and outer weld scraping tools 64 are provided adjacent the welding apparatus with a scrap winder 68. The welded tube then passes through a sizing and straightening mill 70 and is subsequently cut using a flying cutoff 80, e.g. a shear or saw. The cut-off device is controlled by a detector 84, e.g. a photoelectric device or electrical switch which senses the location of the end 82 of the tube emerging from the apparatus and passes signals to a cut-off controller 86. The cut-off 80 is synchronized with the operation of fluting roll 30 so that the tube is cut in a smooth section. Alternatively, controller 86 may be synchronized to operate with roll 30 by connecting it to a synchronizer 36 and taking into account the distance between the rolls 30, 32 and the cutoff 80. Finished lengths of tubing are ejected from the apparatus by ejector arms 90, 92 and roll down an inclined ramp 94. The strip stock 10 may be of copper, copper alloy, stainless steel or other suitable metallic material.
