Title: A process for the production of polyurethane resins
Inventor: KEBERLE WOLFGANG
IPC: C08G18/08
Filed: 1970-12-31
Abstract: 1300852 Polyurethane latices FARBENFABRIKEN BAYER AG 31 Dec 1970 [30 Jan 1970] 62001/70 Heading C3R [Also in Divisions B2 and D1] Aqueous polyurethane latices are prepared by the isocyanate polyaddition process in the presence of water under latex-forming conditions from polyisocyanates, compounds containing ionic groups or groups which are convertible to ionic groups and polyhydroxyl compounds having a M.W. of 300 to 10,000 and which contain bromine linked by homopolar bonds to carbon atoms which are either linked to another carbon atom via a double bond, or which are linked, in addition to hydrogen atoms, to carbon atoms which are saturated by three other carbon-carbon bonds, the polyhydroxyl compounds being used so that the resulting polyurethane has a bromine content of 1 to 50% by weight. Chain lengthening agents having a M.W. up to 300 may also be included in the reaction mixture. The aqueous polyurethane dispersions may be prepared in conventional manner, e.g. by first preparing a prepolymer from the polyisocyanate and bromine - containing polyhydroxyl compound, taking up the prepolymer in an organic solvent, reacting it with the ionic compound, adding water and distilling off the organic solvent. The bromine-containing polyhydroxyl compound is suitably a polyester prepared from a polycarboxylic acid and a glycol such as 1,4-dihydroxy-2,3-dibromo-#<SP>2</SP>- butene, 1,3 - dihydroxy - 2,2 - di - (bromomethyl)propane and 1,3 - dihydroxy - 2- bromomethyl - 2 - ethyl propane. In a typical example a polyester prepared from adipic acid, ethylene glycol and 2,3-dibromobutene-2-diol- (1,4) is reacted with 1,6 - hexane - diisocyanate to form a prepolymer which is taken up in acetone and to the solution is added an aqueous solution of ethylene diamine, propane sultone and potassium hydroxide. Further water is added, the acetone removed and a film formed from the resulting latex. The latices may be used to coat or impregnate natural or synthetic leather paper or textiles. Polyesters may be prepared from 2,3-dibromobutene - 2 - diol - (1,4) and (a) ethylene glycol and adipic acid or (b) diethylene glycol and adipic acid or from 1,3-dihydroxy- 2,2 - di - (bromomethyl)propane, triethylene glycol and adipic acid or from 2-ethyl-2-bromomethyl - propane - 1,3 - diol and (a) hexane- 1,6-diol and adipic acid, (b) adipic acid or (c) phthalic anhydride.
Patent GB-712997-A (GB)
Abstract: 712,997. Photographic processes. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 21, 1952 [June 15, 1951], No. 14292/51, Class 98(2) A method of fast multipicture photography of the type wherein a plurality of views of an object are recorded on the same photographic plate or film in the form of line or point picture elements, the line or point picture elements of one view being interlaced with the picture elements of the other views, comprises exposing the plate or film through a lenticular screen which is operative to dissect the views into their line or point picture elements and moving the light source by which the exposures are made, relative to the lenticular screen, whereby the direction of the picture-forming light rays incident on the lenticular screen is varied 'from exposure to exposure to effect displacement of the picture elements of each view with respect to the others. As shown in Fig. 1, one element of a silhouette picture of an object 1 is formed by light from a source S passing through a lenticular screen 2 to a light sensitive plate or film 5. By displacing source S to position S<SP>1</SP> further picture elements displaced from the first set are imaged on film or plate 5. The source S may be the moving spot of a cathode-ray tube, an electronic gas discharge tube having several discharge electrodes, a moving flame provided, for instance, by a trail of lead azide which may be detonated by an electric spark, or a row of spark gaps. The picture elements so formed can be unscrambled by placing the processed film or plate between a translucent screen 7 and the lenticular screen 2, Fig. 2, and any selected picture of the object 1 may be viewed through an apertured screen 8 which is moved in the plane originally occupied by the light source. In another form of the method, a lightsensitive plate or film 17 is placed behind a lenticular screen 18. An object O is located between lenses 19 and 20 and is illuminated by the moving spot 22 of a cathode-ray tube 21. This spot is imaged at 23 by lens 20 and the object O is imaged by lens 19 near the lenticular screen 18 so that line or point picture elements of the object are formed on plate or film 17 for each position of the cathode-ray tube spot 22. Unscrambling of the pictures formed by this method may be effected by moving the apertured screen 8 of Fig. 2 across the fan of a converging lens arranged to project any given view back through the aperture into a plane corresponding to that of the original object. By positioning light sensitive material to receive the projected view prints can be obtained. To provide a three-dimensional effect when unscrambling, two light sources at a known spacing may be moved simultaneously over the fan of the converging lens 19 when recording.

IPC: F16H3/66
Abstract: 747,321. Change-speed gear; friction clutches. COMPAGNIE DE PONT-AMOUSSON. June 3. 1954 [June 5, 1953; May 14, 1954]. No. 16416/54. Class 80(2) Two reduced ratios, direct-drive, overdrive and reverse are provided by two sunring trains controlled by two input clutches M, N and three brakes F<SP>1</SP>, F<SP>2</SP>, F<SP>3</SP>, as follows. Compounded first speed is by driving the front sun a<SP>2</SP> from the input shaft A through clutch N and outer intermediate shaft D, and braking the rear sun a<SP>1</SP>, at F'. Drive passes through the integral front planet-carried d<SP>2</SP>, and the rear ring b<SP>2</SP> to the integral front ring b<SP>3</SP> and rear planet-carrier d<SP>1</SP>, integral with the output shaft B. Second speed, in the rear train alone, is by changing to the clutch M, leaving the brake F<SP>1</SP> applied, drive now passing through an inner intermediate shaft C through the front planetcarrier d<SP>2</SP> to the rear ring b', and thence through the rear planet-carrier d', to output B. Third speed, direct solid drive, is by engaging both clutches M, N together and releasing all brakes. Fourth speed, overdrive, is in the front train alone, by engaging the clutch M to drive the front planet-carrier d<SP>2</SP> and applying the brake F<SP>2</SP> to the front sun a<SP>1</SP>, drive passing to output B through the integral front ring b<SP>2</SP> and rear carried d<SP>2</SP>. Reverse in the front train alone, is by driving the front sun a<SP>2</SP> through clutch N, and braking the front carrier d<SP>2</SP> at F<SP>2</SP>, drive issuing to output B through the front ring b<SP>2</SP> and rear carrier d<SP>1</SP>. The clutches M N are each engaged by spring- opposed fluid pressure applied through passages 21. 31, and spring-opposed fluid-pressure motors V<SP>1</SP>, V<SP>2</SP>, V<SP>3</SP> apply the brakes. Control is by a single sliding piston distributer-valve (Figs. 2-7, not shown) operated manually, automatically or semi-automatically. In Fig. 8, not shown, the clutch N, which is effective in first and third speeds and reverse is arranged in a separate housing in front of the gear casing, and is used like a normal main clutch on a vehicle, being, in this case, spring engaged and released by. fluid-pressure and also a mechanical pedal, the distributer-valve porting being changed to suit. In Fig. 10, a clutch N<SP>2</SP> similarly arranged in a separate housing, is engaged, in opposition to a spring 105 by energizing an electro-magnetic winding 93 under control of contacts operated by cam-notches in the side of the piston distributer-valve (Fig. 11, not shown), to engage and release in the required sequence. The gap of the splined driven armature 102 is limited by an abutment ring 106.
