Patent FI-80173-C (FI)

IPC: H04B15/00

Granted: 1990-04-10
Abstract: The invention relates to a method for the elimination of noise in an information channel. The frequency band of the channel (1) is first divided (CH1-CH4) into sub-bands (B1-B4), whereafter the useful value of the signal of each sub-band (B) is determined by comparing the signal level (S) to a reference level (Ref), in which case a constant signal of substantially the same level as the reference level (Ref) is suppressed (P1-P4), whereas a varying signal, defined as a useful signal, is summated, unsuppressed, with the useful signals of the other sub-bands (B1-B4). The frequency band of the channel is divided into sub-bands (CH1-CH4) by means of an all-pass filter construction. The method can be implemented using an analog or a digital filter construction.

IPC: H04L25/49
Abstract: 656,184. Electric signalling systems. STAATSBEDRIJF DER POSTERIJEN TELEGRAFIE EN TELEFONIE. Dec. 30, 1947, No. 34844. Convention date, Aug. 22, 1944. [Class 40 (i)] [Also in Group XXXIX] A receiver for responding selectively to a potential applied to a signalling wire comprises a chain of four valves BA ... BD with relays A ... D in their anode circuits, the grid bias of the valves being derived from a potentiometer including resistances which are switched in and out by relays B ... D to shift the bias of the valves earlier in the chain, with the result that different combinations of relays are operated as the signalling potential is varied in steps. As shown, the signalling potential is variable from a normal value of - 30 volts by steps of - 2 volts to - 60 volts, and the valves, which are pentodes, have a normal bias of - 32, - 34, - 38 and - 46 volts respectively. A signalling potential of - 32 volts operates A, whereas a potential of - 34 or - 36 volts operates B which immediately makes the bias of BA 4 volts more negative, so that A operates only in the latter case. In the same way, the operation of C by a potential of - 38 to - 44 volts alters the bias of both BA and BB to determine the potential more accurately. The relays A, B, C have opposing windings in series respectively with operating windings of B, C, D, thereby preventing momentary and possibly false operation of, say A, by a signalling voltage sufficient to operate B ; the possible operation of A being delayed until B has shifted the bias on BA, whereupon the opposing winding of A is short-circuited and A may operate if the signalling voltage and the new bias bear the correct relationship. Specification 655,369 is referred to.
Patent NL-64058-C (NL)
IPC: C23C22/24
Abstract: Metal surfaces are protected against corrosion by applying thereto an acid solution stable to light, having a pH of 3.5 or more composed of gelatine or other animal glue and a tanning agent chosen from the group consisting of chromates or dichromates of metals, the hydroxides of which are insoluble in water, the gelatine being rendered insoluble by decreasing the pH figure of the admixture.  The pH may be reduced by evaporating off the water or by the presence of acid ions remaining after pickling of the metal.  Specified tanning agents are manganese and/or zinc dichromates.  Preferred proportions are from 0.1 to 2 per cent gelatin and 1 to 10 per cent manganese and/or zinc dichromates. Auxiliary substances e.g. wetting agents such as sulphoricinoleic acid, plasticizers such as glycerine and colouring agents may also be present.  Several treatments may be used and a layer of paint may be applied as an overcoat.

Abstract: A method and a boiler for heating a heat-transfer medium such as water in a heating system. The combustion gases are brought into heat-transfer contact with the heat-transfer medium over a large specific, heat-transfer surface. The heat-transfer medium flows in the opposite direction to the combustion gases and the gases are caused to flow downwardly and are thereby cooled to a temperature which is lower than the temperature at the outlet for the medium heated by the gases before the gases are discharged to atmosphere.The boiler is fired by oil and/or gas and the combustion chamber (16) is arranged immediately above one end of the smoke-pipes (22). The other end of the smoke-pipes (22) discharge into a collecting chamber (24) provided with an outlet (28) for the combustion gases. The collecting chamber (24) is provided with an outlet (34) for condensation from the combustion gases.

Abstract: Apparatus is disclosed for detecting the presence of shiny tape on a printed note, for example a banknote. An optical fibre fishtail array supplies visible light from a source (A) to a lengthwise strip of the banknote. A first array of photodetectors (D) detects light specularly reflected from a plurality of adjacent regions of the said strip, while a second array (B) arranged parallel to the first array (D) detects light reflected diffusely from corresponding ones of the said regions. An analysing circuit receives signals from the photodetectors and indicates when the ratio of specularly reflected light from an illuminated element of the banknote to diffusely reflected light from the same element exceeds a predetermined value.

Abstract: A polymer composition usable far the production of articles of biodegradable plastics material includes an ethylene/vinyl alcohol copolymer and destructured starch.      Preferably, the composition is obtainable by mixing the ethylene/vinyl alcohol copolymer, in a heated extruder, with a starch component constituted by a destructured starch composition produced beforehand by mixing starch with a high-boiling plasticizer, such as glycerine and a destructuring agent, preferably constituted by urea, in an extruder. Alternatively, the composition can be obtained by mixing the ethylene/vinyl alcohol copolymer with starch. and a plasticizer in an extruder, with water added as appropriate and possibly with a suitable destructuring agent.      The composition is particularly useful for the production of films with good resistance to perforation and tearing and moulded articles with improved mechanical strength.
