Patent EP-0000241-A1 (EP)
Inventor: RIGGS AUBREY FRANK
IPC: B05C1/08
Filed: 1978-06-02
Abstract: Process and apparatus for applying a flowable coating medium to a travelling web by a reverse applicator roll technique in which the peripheral velocity of the applicator roll (U) is maintained at less than 0.4 of the forward speed of the web, and the dynamic viscosity of the coating medium (η)is selected in accordance with the relationship h = k η   0.5 U O.5 , wherein k is from 0.01 to 100, such that a layer of coating medium of equilibrium thickness (h) not exceeding 5.0 mm is entrained on the surface of the applicator roll for transfer to the web. The technique avoids the use of a doctor blade to meter the amount of coating medium on the applicator roll, and is suitable for the high speed application of a heat sealable coating laver onto a polymeric packaging film. Coating qualitv can be imoroved by stabiiising the web downstream ofthe appiicator roll.

Abstract: Binary signals are frequently combined from multi-level digital signals for the optimal utilisation of the transmission capacity of digital transmission links. For this purpose, the binary signals are subjected to a weighted addition. At very high bit rates, problems occur with respect to the exact weighting and the reaction-free addition. According to the invention, a circuit arrangement based on a base-coupled differential amplifier (T1, T2) is proposed in which the differential amplifier is preceded by a number of emitter-coupled differential amplifiers (T3, T4...T2n+1, T2n+2) corresponding to the number of input signals. <IMAGE>

Abstract: In a sample-and-hold circuit having a first MOS transistor (5) for sampling an input voltage and a holding capacitor (C o ) for holding the sampled voltage, a second MOS transistor (10) has its source and its drain both connected to the output terminal (4) of the circuit. The capacitance between the gate and output electrode (S) of the first MOS transistor (5) is substantially equal to the sum of the capacitances between the gate and the drain, and between the gate and the source, of the second MOS transistor (10). When a voltage is applied to the gate of the first MOS transistor to turn it on or off, the gate of the second MOS transistor receives the same voltage after inversion (8), so that the charge accumulated in the channel region of the first transistor, can be absorbed in the channel region of the second transistor when the first transistor is turned off. In this way, the sampled voltage can be held constant after turning off the first MOS transistor.

Abstract: A molecular glass based upon a phosphate of aluminum, or other trivalent metal, provides significant improvement over prior art glasses for encapsulation of high level radioactive nuclear waste. When containing a controlled amount of those elemental oxides found in a typical nuclear waste, the waste-glass would not devitrify under conditions which produced devitrification in the non-nuclear-waste- containing glass, exhibited hydrolysis losses lower by an order of magnitude, had high solvency power for those elemental oxides, exhibited little tendency for internal crystallite formation, and possessed other desirable physical characteristics, all in direct antithesis to the properties of the best prior-known glasses used for this application.
