Patent EP-0118823-A2 (EP)
Inventor: STEINER RUDOLF DR
IPC: G01J1/16
Filed: 1984-02-28
Abstract: A method of determining turbidity in liquids by irradiating the liquid with electromagnetic radiation and measuring the scattered light intensity, and also a device for carrying out said method. The method is characterised in that the scattered light intensities from a test cell and a reference cell are combined alternately and with reversed sign to form a rectangular analog signal of frequency f and sampled with a frequency of n times f, and the difference is taken of the product sums of corner cells of this time series with the cycle time of the frequency f and the time interval T. The novel method eliminates errors due to inherent turbidity in the liquids being examined, it greatly improves the signal/noise ratio and it consequently increases the detection sensitivity.

Abstract: An arrangement comprising a host switching system and a number of remote switching modules which are directly interconnected such that voice and data traffic as well as control information can be conveyed between modules without being routed through the host system network. The arrangement allows the integrated standalone operation of the remote switching modules and advantageously reduces traffic through the host system network during normal operation. For each pair of remote switching modules, one of the modules selects the channels of the direct interconnection which are used for conveying information between the modules.

Abstract: C2H4 is homo- or co-polymerised with an alpha-olefin at 300-3500 bar and 150-350 deg.C, in the presence of a catalyst consisting of a transition metal cpd. and an organic Al cpd. The catalyst system is treated with a sufficient amt. of at least one deactivator so that the reaction prods. of deactivation can remain in the polymer. Novelty consists in using polyglycols as the deactivators. Pref. polyglycols are: (i) derived esp. from ethylene oxide and/or propylene oxide as monomer units, (ii) have mol. wt. 500-10000 (1000-5000) and (iii) are prepd. esp. by the oligomerisation or polymerisation of C2H4O with C3H6O. Pref. polyglycols can be charged directly in front or directly behind the reactor outlet valve. When carrying out polymerisation in a tubular reactor, the polyglycol are fed into the reactor at a position which is 1/5 to 1/2 of the reactor length in front of the outlet valve. Pref. amt. of polyglycols charged is 0.1-0.02 (0.02-0.005) mol/mol (Al + transition metal). Pref. polyglycols may be charged in pure form or as solns., e.g. in aliphatic and/or aromatic hydrocarbons.

Abstract: In order to minimize the size of an auxiliary coolant reservoir and to ensure that the appropriate control is executed over the system during all phases of engine operation, a control circuit including a microprocessor is arranged to selectively induce a non-condensible purge mode, cold start mode, normal operation mode, overcooled mode and a system shut- down mode. The latter mentioned mode allows for the coolant to cool down before the system is switched from closed to open states and minimizes the tendency for coolant to be displaced from the system in large quantities under the influence of a positive pressure which tends to prevail at the time the engine is stopped. Control of the various modes is facilitated by a valve/conduiting arrangement which features three basic conduits each of which include one ON/OFF type electromagnetic valve.

Abstract: An ALU 10, performing selected operations on input operands in a predetermined clock cycle, uses means for detecting 40 a carry propagation path greater than a predetermined number of consecutive bit positions to cause a stretching of the clock cycle. Since such a long carry propagation path is detected for only a very small percentage of all operations, the cycle is normally shorter than otherwise possible, and, thus, the performance of a system using such an improved ALU is increased.

Abstract: The proposed circuit is a so-called timer IC in which a time constant is determined by a capacitor. This capacitor is integrated in the electrical circuit in such a way that the time constant is controlled by a controllable charging current of the capacitor. At the same time, the charging current of the capacitor is reduced by a selectable factor. The integrated time constant determined in this way can be used to determine the frequency of a completely integrated multivibrator, the latter being capable of achieving low frequencies which could hitherto only be achieved with external capacitors. <IMAGE>

Abstract: A method of making a metal can end with a tear-open plastics closure, for a can intended to be resistant to leakage when subject to internal pressures, such as arise from carbonation of a beverage or thermal processing, wherein the undersurface of the can end is provided with a plastics coating (14). and the can end is pierced to form an aperture (15) with a peripheral downturned flange (16) at an angle of 80° to 120° to the plane of the can end and having a flat end. A one-piece ring pull closure is injection moulded on to the can end (10) from a plastics material resistant to softening at up to at least 65°C, without additional heating of the metal, so as to fill the aperture (15), bond with the coating (14), and enclose the flange (16), with a residual thickness below the flange of 0.08 to 0.5 mm. The thickness of the plastics material of the closure is such that it can be sheared against the flange when the ring pull (26) is pulled manually. The residual thickness of the plastics material may be varied around the aperture to increase resistance of the closure to creep, and the aperture may be pear-shaped or may be circular with a separate vent hole.
