Abstract: 1357973 Thermally reversible coacervates BAYER AG 25 Nov 1971 [9 Dec 1970] 54794/71 Heading C3P Aqueous copolymer solutions which undergo thermally reversible coacervation are prepared by copolymerizing 25 to 70 mol per cent acrylic acid with 75 to 30 mol per cent acrylamide in aqueous solution in the presence of a free radical catalyst and lowering the pH to below 3À3 before, during or after the polymerization. The catalyst may be a peroxide, azo compound or redox catalyst, and the pH may be adjusted with strong acids, e.g. sulphuric, hydrochloric, phosphoric, nitric and halogen-substituted carboxylic acids. The products may be used in the production of coatings, coverings and microcapsules.

Title: A method and apparatus for measuring the energy and/or dose of radiation by radiation-sensitive transparent solid body measuring elements
IPC: G01T1/10
Filed: 1968-11-26
Abstract: 1,248,965. Lumiescent materials and uses thereof. GES. FUER KERNFORSCHUNG m.b.H. 26 Nov., 1968 [28 Nov., 1967], No. 55950/68. Heading C4S. [Also in Division G1] During readout of a dosimeter element, the intensity of fluorescence from a number of zones, which are located at different distances from the surface of the element which was subjected to the original irradiation, is measured so that information as to the energy of the original radiation can be determined before the actual dose is calculated. This because for certain radiation fields (particularly in low energy medical and technical applications) the dose absorbed by the element is energy dependent. With a cube-shaped element 1, Fig. 1, the surface which was irradiated is known, and the element is displaced at right angles to this surface (in the X direction). A masking arrangement 4 allows excitation of the element, which may be a low Z phosphate glass, by ultra-violet radiation, in the Y direction, and detection of fluorescence emitted in the Z direction by a narrow zone of the element. The detector may be a photomultiplier. The displacement may be step-by-step or continuously, in the latter case the detector being coupled to a chart recorder. In an alternative arrangement, a light conductor is moved across the fluorescent surface. In the case of a cylindrical block element, the direction of incidence of the original radiation is first detected by locating the part of the surface producing maximum fluorescence. Once this is found, fluorescence in zones spaced further and further from the originally irradiated part of the surface may be measured. A graph of intensity of fluorescence against distance (or depth) of a luminescent zone from the originally irradiated surface may then be drawn and compared with calibration curves for different energies of the original radiation, Fig. 4 (not shown), which curves have differing shapes (steeper with decreasing energies), to determine the energy and dose of the original radiation that the element was subjected to. Values for tissue equivalent doses may also be calculated therefrom. Reference is made to γ- and X-radiation and also # radiation.

A coin-freed vending machine for newspapers includes a reciprocable plate 16 for separating the bottom newspaper from a stack, the plate having a bristle surface 42 inclined in the direction of feed. Coin acceptance units 13 direct suitable coins to close microswitches or bridge contacts in the circuit of a solenoid 28 controlling a latch 30 co-operating with the plate 16. The plate 16 is reciprocated by a handle 27 cranked at its inner end and engaging a depending guide 25 on the plate. Alternatively, the plate is reciprocated by an electric, pneumatic, spring or weight motor or by a vibrator. Movement of the handle 27 moves the electric contacts aside to release the coins to a coin box. An adjustable stop 44 prevents double feed of the newspapers. A pivoted feeder engaging the bottom of the stack, lowers a rod 50 when the stack is exhausted to display an " empty " sign 52 in a window and place a bar 53 across the coin slots.

The sheet material may be subsequently soaked in a liquid comprising a major amount of water together with for example methanol and acetone to increase removal of water miscible solvent from the material. After either the step of casting or drying the sheet material an optional embodiment includes the step of adhering a layer of fabric or foam to the exposed surface of the material to form a laminate. The layer may be cast by blade coating or extruding the layer and the viscosity of the solution should be 10,000 to 75,000 cps and preferably 20,000 to 30,000 cps. Examples of releasable substrates are chromeferrous plates, polished steel surfaces, glass plates and polytetrefluoroethylene surfaces. In a further embodiment a thin layer of a solution of a hard wearing polymer is cast on to the releasable substrate, dried (not phase inverted) and then proceeding as previously described with the steam atmosphere phase-inverting the second layer. The reinforced sheet material may also be laminated as described above.
