Patent NL-272790-A (NL)
IPC: G10L25/00
Filed: 1961-12-21
Abstract: 936,124. Vocoders. MINISTER OF AVIATION. Dec. 18, 1961 [Dec. 30, 1960], No. 44730/60. Class 40 (4). In a formant tracker for an analysis synthesis telephone transmission system an adjustable network operates on the incoming speech and a signal is derived which is rectified and fed back to adjust the network continuously so that the network output is the original speech operated on by substantially the inverse of at least some of the formant forming filters of the vocal tract, whereby the signal derived is constrained to be representative of the corresponding formant parameter of the input speech signal. Fig. 1 shows a block diagram of a preferred embodiment for deriving tracking signals at O1 and 02, corresponding to the two lower formants of the speech input at I1, the tracking signals being amplified and fed back via I2 and I3 to control the characteristics of the network. It is shown mathematically that, assuming the speech signal can be represented as where p is the Heaviside operator, w 1  and w 2  are the two lower formant angular frequencies, and P 1 (t) is a function dependent on the excitation and other characteristics of the vocal tract, the output of adder S1, Fig. 1, will be (1+ap<SP>2</SP>)S(t), where a is the signal applied via input 12 to multiplier M1, (if a = 1/x 1 <SP>2</SP> this x 1 <SP>2</SP> function (1+ap<SP>2</SP>) is the inverse of the function which represents the effect of the formant angular frequency w 1  on the original speech and thus (1+ap<SP>2</SP>)S(t) will represent the speech signal with the component due to the formant w 1  removed. Similarly, the output of adder S2[= (1+ap<SP>2</SP>)] will represent the speech signal with the component due to formant w 2  removed. The output of adder S3 will be (1+abp<SP>4</SP>+ap<SP>2</SP>+ bp<SP>2</SP>)S(t) = (1+ap<SP>2</SP>)(1+bp<SP>2</SP>)S(t) and if a and b are correct (i.e. = 1/w 1 <SP>2</SP> and 1/w 2 <SP>2</SP> respectively) will   contain no components due to either formants w<SP>1</SP> 1  or w 2 , but if one of the formants say w 1 , is incorrectly tracked there will be an output from this adder S3 which will be in phase with the output from one of the adders, i.e. S2, and these signals applied to the inputs of phase-sensitive detector P2 will produce an output dependent in magnitude and direction on the difference 1 between a and +- which output, after integraw 1 <SP>2</SP> tion and amplification, is applied to input I2 to adjust the network to eliminate the formant corresponding to the angular frequency w 1  from the outputs of adders S3 and S1. A circuit is described with respect to Fig. 2 (not shown), incorporating compensation for the limitation of frequency response of practical differentiating networks.

Title: Crystal fibres
IPC: C23C16/06
Filed: 1969-03-07
Abstract: Crystal fibres are produced in a device comprising a chamber, means for forming a number of longitudinal fibres by the condensation of fibrous crystals from a vapour stage of fibre producing material in the chamber and means for electrostatically charging fibres so as to spread the ends of the fibrs in fan-shape so that the ends are separated and separately exposed to the vapour. Means for gathering the fibres together at some distance from the ends, so that the ends remain separated, are specifically provided. Specifically, the vapour-deposited, whisker material is carbon, such as sapphire, and a gaseous metal mix, consisting of nickel- or iron-carbonyl is precipitated on the whisker by decomposition.

Title: Fusing lamp bulbs and frames - in a heating zone with uniform heating and cooling profile
IPC: H01J9/46
Filed: 1975-10-23
Abstract: In the fusion of rotationally symmetrical glass bodies, individual components such as the bulbs and frames of incandescent lamps and other products of vacuum technology, the glass bodies to be joined are held in specific positions, set into rotation, heated by means of burner jet, supplied with fuel gas/or mixture or if necessary oxygen, formed and fused together. The glass bodies held part at specific distance and set in rotation are advanced continuously along a pref. linear heating zone of pre-determined length at pre-determined speed, the heating zone being formed by a series of locally fixed glass flames on one side of the transport path, and a heat storage and radiating wall fixed opposite. Risk of constant breakage is avoided and increased and stabilised output is obtd. by uniform heating and cooling of the lamp bulbs and frames.

Title: Purificn. of chloride-contg. conc. aq. sodium hydroxide soln. - by treatment with basic ion exchanger
IPC: C01D1/32
Filed: 1977-05-09
Abstract: Chloride-contg. NaOH is purified by passing a conc. aq. soln. contg >=20 wt.% of the NaOH over a basic ion exchanger. The ion exchanger is then regenerated by diluting the conc. alkali in the exchanger bed to a concn.of 20 wt.% and separating the dil. alkali from the ion exchanger. The process is simple and economical and gives good reduction in chloride content of conc. NaOH solns. This allows the use of membrance cell electrolysis in the prodn. of NaOH in place of the previously used mercury process, which gives rise to environmentally polluting effluent streams. The membrance cell however gives NaOH solns. with a high chloride content (e.g. >=10000 ppm) which can cause stress corrosion and/or pitting corrosion of chrome nickel and austenitic stainless steels.

Title: Method and apparatus for biochemical purification of a liquid medium
Inventor: MAEHL DIETER
IPC: C02F3/00
Filed: 1994-05-27
Abstract: The invention relates to a method and apparatus for biochemical purification of a contaminated liquid medium, wherein the liquid medium is passed through a granular filter material disposed in a container, and wherein the granular filter material present in the container is set in motion, preferably with the aid of an injected gas such as air. The container can be supplied with microorganisms and/or an activated water for microorganisms. The filter material can comprise a mixture of lava and sand, for example from 28% to 38% sand and from 61% to 71% lava. The grain size of the sand is from 0.3 to 1.2 mm, and the grain size of the lava is from 2 mm to 10 mm. The main flow of the medium to be purified and of the injected gas are countercurrent. To set the filter material in motion, use is advantageously made of an inner tube positioned in an outer tube, gas being blown through the inner tube below the bottom end of the inner tube, so that gas and filter material aspirated at the bottom end of the tubes and medium are transported upwards through the inner tube.
