Title: Manufacture of chlorine
IPC: C01B7/04
Filed: 1963-11-13
Abstract: <PICT:1011614/C1/1> Chlorine is produced by contacting HCl and/or NH4Cl with moving beds of inert granular supports integrated with chlorides or oxides of Fe, and with chlorides of Cu or of Cd, and with alkali metal chlorides and flowing by gravity through superimposed reaction chambers wherein occur successively reduction, chlorination and oxidation of the masses, the oxidation being carried out in two stages comprising (1) re-oxidation of the metals of the integrating salts to their maximum valency and (2) oxidizing dechlorination of said salts, whereby Cl2 is liberated. The apparatus used may be essentially that described in Specification 1,005,771, with addition of a fourth chamber, chamber 3 being used for re-oxidation and chamber 4 (see Figure) for dechlorination. The latter has inlet 11 for oxidizing gas and outlet 12 for the Cl2-containing gases produced, part of which may be fed into chamber 3 through conduit 7 to provide just sufficient Cl2 to effect the re-oxidation. Alternatively, re-oxidation may be effected by injection of about one-third of the total requirement of O2 into inlet 9. NH3 may be recovered from NH3-metallic chloride complexes formed during chlorination by sweeping the granules with inert gas.

Title: Sterilizing method and apparatus
IPC: B65B55/10
Filed: 1968-10-14
Abstract: A web 1 of paper, coated in one or both sides with plastics, is subjected to the action of a fluid sterilizing medium at a pressure above atmospheric during passage through a packaging machine wherein, on passing from a feed roller 2 to a transversely aligned roller 3, the web 1 is folded along its length and is then fed over a roller 4 to a filling station at which the edges of the folded web are sealed by a device 19 to form a tube 20 into which material is deposited by a filling pipe 17. The tube 20 is transversely sealed to form individual packages, either before or after material is introduced therein, which are then separated by cutting at the seals. During passage between the rolls 2 and 3, the surfaces of the web 1 which are to form the interior of the tube 20 are enclosed by a channel 10 having upstanding side walls 11 and into which is fed, through nozzles 13 or 13a, hydrogen peroxide which is decomposed into steam and nascent oxygen by hot air fed under pressure through inlets 14. A portion of the sterilizing medium is tapped off from the channel 10 by a pipe 32 to a chamber 8 enclosing the filling pipe 17 and the sealing device 19, and the remainder is sucked off adjacent the roll 3 through a pipe 33 and recycled, in a valveadjusted ratio, by a fan 23 which introduces the sterilizing air, from atmosphere through a filter 24, into the apparatus. During passage between the rolls 3 and 4 the folded web 1 is enclosed on all sides in a channel 15 into which heated sterilized air is introduced under pressure, through a pipe 16, to prevent the ingress of unsterile air and to evaporate sterilizing fluid entrapped in the folded web 1. The chamber 8 enclosing the filling pipe 17 and sealing device 19 is fed from the pipe 32 with the sterilizing medium comprising steam and oxygen under pressure and, in addition, any steam remaining within the interior of the tube 20 is dried off by sterilized air introduced under pressure through a pipe 18. The sterilizing hydrogen peroxide is introduced to the nozzles 13 from a tank 21, via a valve 28. A sensing device 37 is arranged to close the valve 28 and to open a similar valve 28a in a pipe 22a leading to the nozzles 13a, whenever the delivery from nozzles 13 is interrupted. The air supply introduced by the fan 23 is delivered through a heater 25, where its temperature is raised to 140- 170 C., and one portion thereof flows through a diversion valve 27, via pipes 28, 29 and 31, to the nozzles 14, and the remainder flows, via a cooler 36, to the pipes 16 and 18 respectively supplying the channel 15 and chamber 8. In the event of the travel of the web 1 through the machine being interrupted, the valve 27 functions to divert the hot air supply from heater 25 through a cooler 38, where its temperature is reduced to 80 C. or lower, whereby softening of the plastics coating of the web 1 is avoided. The apparatus is initially sterilized at the commencement of production by steam introduced through a valve 41.

Patent ES-450719-A1 (ES)
Title: Arrangement for recognizing sounds
IPC: G10L15/02
Filed: 1976-08-14
Abstract: Sounds or speech signals are converted into an electrical sound and broken down into separate spectral components in a filter bank. These components are integrated over a short period of time and produce a short-time spectrum of the signal. The spectal components are applied, via a corresponding number of parallel leads, to a number of pattern detectors which supply an output signal only if the short-time spectrum corresponds to the pattern adjusted in the relevant pattern detector. To this end, each pattern detector includes two threshold value (window) detectors which supply a signal if the applied input signal lies between two adjustable thresholds. Each threshold value detector is connected to a different output of the filter bank for another spectral range and is generally adjusted to different threshold values. The outputs of the threshold value detectors are combined via an AND-element, so that a signal is produced only if all threshold value detectors of the pattern detector are activated. For each sound or for each phoneme in the case of speech, a pattern detector is provided. When series of sounds or signals are recognized, the series of addresses of the pattern detectors which have successively generated an output signal are stored and subsequently applied to the computer for comparison.
