Abstract: 746,708. Recording-apparatus. MATERIEL INDUSTRIEL SOC. ANON., and CONSTRUCTIONS MECANIQUES SOC. ANON. April 9, 1954 [April 10, 1953], No. 10558/54. Class 106 (4). [Also in Group XXX] The warp of a railway track is obtained by recording continuously the relative angular displacement in a vertical plane of the axles 1,2 of two pairs of wheels 3, 4; 5, 6; running on the rails 7, 8 and compelled to maintain contact therewith. In one embodiment, Fig. 1, two coaxial relatively rotatable members 19, 20 transmit relative angular movements of crossbars 9, 10 supported on the axle-boxes of the wheels through cable 23 and sheath 24 to a pen 26 which records on a strip 27 driven always in the same direction through reversible gearing 30 from a pulley 28 on the axle I irrespective of the direction of movement of the vehicle. In another embodiment the axles of the wheels are linked by universal couplings to coaxial members whose relative rotation causes relative movement of a sheath and cable to actuate a pen. The invention is also applicable to roadways without railway tracks.

Title: Ternary acrylonitrile polymers
IPC: C08F26/06
Filed: 1951-05-07
Abstract: Copolymers are prepared containing 70 to 84 per cent of acrylonitrile, 6 to 20 per cent of methacrylonitrile, and 1 to 10 per cent of a vinyl-substituted heterocyclic tert.-amine such as 2-, 3-, and 4-vinyl pyridines, 4-methyl-3-vinyl pyridine, 2-methyl-5-vinyl pyridine, 6-methyl - 2 - vinyl pyridine, 4,6 - dimethyl - 2 - vinyl pyridine, 4 - ethyl - 2 - vinyl pyridine, 5 - ethyl - 3 - vinyl pyridine, 5 - ethyl - 2 - vinyl pyridine, 1-vinyl imidazole, 2-, 4-, or 5-methyl-vinyl imidazole, vinyl pyrazines, vinyl quinolines, vinyl oxazoles, and vinyl p  benzoxazoles.  Polymerization may be carried out in aqueous emulsion employing an emulsifying agent such as a mixture of the sodium salts of short-chain alkyl naphthalene sulphonic acids, or by a solution process wherein the solution is saturated with a mixture of the three monomers in a predetermined ratio. Polymerization catalysts may be employed such as benzoyl peroxide, acetyl peroxide, tert.-butyl hydroperoxide, isopropyl percarbonate, sodium peroxide, sodium perborate, sodium and potassium persulphates, and azo-2,21-di-isobutyronitrile, and activators for the catalysts such as triethanolamine and sodium bisulphite.  The copolymers may be modified by carrying out polymerization in the presence of molecular weight regulators such as dodecyl mercaptan, dithioglycidol, and carbon tetrachloride. Polymerization is preferably conducted by initiating polymerization and then adding further quantities of the monomers and catalyst as the reaction proceeds.  The copolymers are soluble in N,N-dimethylformamide, N,N - dimethylacetamide, dimethyl sulphone, N-formyl morpholine, N-isopropyl - N - cyanomethylformamide, tetramethylene sulphoxide, and succinonitrile, and from the solutions filaments, films, foils, sheets, casings, tubes and rods may be prepared.  Filaments may be made by dry or wet spinning processes.  When employing the wet spinning procedure the copolymer solution may be coagulated by a mixture of water and the copolymer solvent, glycerol, the mixture of aromatic hydrocarbons known under the Registered Trade Mark "Solvesso-100," or isopropanol.  The filaments produced are stretched, and may be dyed in acid dyebaths.ALSO:Copolymers containing 70 to 84 per cent of acrylonitrile, 6 to 20 per cent of methacrylonitrile, and 1 to 10 per cent of a vinyl substituted heterocyclic tert.-amine, such as vinyl pyridines, quinolines, imidazoles, pyrazines, oxazoles, and benzoxazoles, are formed into fibres and films which are dyed in acid dyebaths.

Title: Radiation position detectors
IPC: G01T1/164
Filed: 1972-03-08
Abstract: 1427722 Position finding apparatus NATIONAL RESEARCH DEVELOPMENT CORP 1 March 1973 [8 March 1972] 10798/72 Heading H4D Apparatus for detecting the position of radiation sources comprises planar detection means for providing first signals representing the coordinates of received radiation; a focused collimator adjacent said detection plane having channels whose axes converge to a focal point; means for causing movement of the collimator such that the focal point moves in a first plane transverse to the said axes and means for deriving the co-ordinates of the intersection of the path of the radiation and a predetermined plane. In a gamma-ray camera Fig. 1, a screen 3 has channels whose axes intersect at a focal point 4. Radiation from gamma-ray sources pass through the channels and impinge on scintillation crystal 5. Phototubes 6 provide signals representing the co-ordinates of the scintillations relative to the camera axis N. These co-ordinates are multiplied by a factor Z 0 /F. where Z 0  selects a plane and F is the camera focal length. For sources on the plane Z 0  from the focus 4, this results in a true representation of the source co-ordinates. For scintillation caused by sources not in plane Z 0 , the coordinates are incorrect. As the camera is scanned over the body under investigation, repeated scintillation due to sources in the selected plane produce a bright image on a display, but sources off the plane Z 0  produce a blurred image since the computed co-ordinates will be different for each scintillation. In the complete system Fig. 2, five separate displays of five planes are produced. The detected scintillation co-ordinates X, Y are multiplied by the five preselected ratios and combined with the co-ordinates representing the position of the couch 7 carrying the patient in a resistor network 10 to provide five pairs of true co-ordinates X 1 -X 5 , Y 1 -Y 5 . These pairs of signals also carry bias voltages to separate the displays on the CRT 12 (Fig. 3A, not shown). A pulse height decoder 14 detects valid pulses and triggers five clock pulses from generator 16. These are used to successively connect the five co-ordinate pairs to the CRT display 12.

Title: Improvements in or relating to brakes for vehicles particularly the compressed air or vacuum brakes of railway or similar vehicles
IPC: B61H13/32
Filed: 1921-04-15
Abstract: 161,921. Scheuer, A., and Scheuer, H. April 16, 1920, [Convention date]. Force-transmitting mechanism.-Transmission gear for vehicle brakes particularly fluid pressure brakes comprises a lever which is moved first about one pivotal point to bring the brake block rapidly into contact with the wheel and is then caused to move about a second pivotal point constituted by an eccentric or cam moved into position by the mitral movement of the brake so that the lever acts at a greater mechanical advantage. A brake lever 3 is actuated by a piston through a rod 1, a rod 15 being provided for separate band actuation. The lever turns initially about a pin 6, supported by a yoke 7 controlled by a spring 9 and embracing the spindle 10 on a squared part of which is mounted a cam 12. When the brake shoe makes contact with the wheel the further motion of the rod 1 causes extension of the spring 9 and motion of the yoke 7 which releases from engagement by a locking- wedge 8 the shaft 10, thus allowing the cam 12 to fall into position for engagement by the lever 3 so as to provide a fulcrum therefor. On release of the pressure the yoke 7 returns towards normal position until the wedge 8 contacts with the inclined part of the shaft 10 causing the rotation of the shaft and the withdrawal of the cam. The cam is automatically adjustable longitudinally on the shaft 10 by a rod 11 connected to the body of the vehicle or the bearing springs whereby the final leverage is varied in accordance with the lead. In a modification, Fig. 9, the rotation of the shaft 10 and cam 12 is effected by a crank 18 and rod 19 connected to the lever 3, and in a further modification, Fig. 13, a horizontally arranged cam 12 is moved into operative position by a link 5<1> and spring connection 5<11>.

Abstract: 1534246 Shrink wrapping stacked objects E MOLLERS 16 March 1977 [3 April 1976 22 Jan 1977] 11085/77 Heading B8C  A pallet-less shrink-wrapped block of objects, e.g. bags, having a pair of fork-lift engageable recesses H at its base is formed by building a stack in which the top layer is of lesser area than the preceding layers to form side edge recesses H, pulling a first heat-shrinkable plastics bonnet SH1 down over the top of the stack, heat-shrinking the bonnet in position, inverting the thus-wrapped stack, pulling a second heatshrinkable plastics bonnet SH2 down over the top of the inverted stack, and heat-shrinking the second bonnet into position in which it is welded at overlapping regions to the first bonnet. The bags are stacked by apparatus 1 and an additional plastics foil sheet K is applied across the stack before adding the top bag layer. The first bonnet is applied by a pull-on device 2 prior to passing to a heat-shrink furnace 3. The latter preferably incorporates reciprocable pressure bars 7 to press the bonnet into the recesses H and weld it to the sheet K. In addition, or alternatively, a device, comprising pivotal Z-shaped presser elements (20) mounted on a reciprocably-movable rockable cross-bar (15), Fig. 4 (not shown), may be utilized downstream of the furnace to conform the bonnet to the recesses. The stack is then carried into an inverter 4, Fig. 2 (not shown), comprising opposed upper and lower horizontal endless belts (9) carried by vertical guides (8) running in vertical guide rails (10) so that the belts may be vertically moved towards and away from each other. The guide rails are carried on horizontal trunnions (11) to permit inversion of stack carried between the belts. The stack is retained in position during inversion by lateral side plates (13) and by driving the belts in opposite directions. The inverted stack is then carried through a second bonnet pull-on device 5 and a second heat-shrink furnace 6. Alternatively, the second pull-on device 5 and second furnace 6 may be omitted, the stack passing through the inverter positioned between a bonnet pull-on device and furnace, the inverter being actuated only after the first bonnet has been shrunk on. A device to further conform the bonnet(s) to the recesses may be located downstream of the furnace 6 and comprise a vertically-displaceable conveyer (25), a reciprocable stop (28), a leading recess engaging roller block (30) and a trailing recess-engaging pivotal presser plate (31), Fig. 5 (not shown).
