Patent NL-301922-A (NL)
IPC: H04N5/44
Filed: 1963-12-16
Abstract: 1,022,306. Electrical filter networks; multiplex radio signalling. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Dec. 30, 1963 [Jan. 2, 1963], No. 51137/63. Headings H3U and H4L. A band-pass filter for passing a comparatively wide frequency range and also for suppressing a comparatively narrow frequency band adjacent to said wide range, comprises series branches I, II, each constituted by a seriesresonant circuit tuned to the mid-point of the wide range and a shunt branch comprising individual branches III, IV each comprising series-resonant circuits tuned to the narrow band, the branch IV being coupled across capacitor 35 forming part of branch III. The input signal which may bea television intermediate-frequency signal is applied to input terminals on the left and the output signal from which signals, e.g. sound carrier, within the comparatively narrow band have been suppressed appears across capacitor 21 which may be the input capacitance of a vision intermediate frequency amplifier valve, Fig. 3 (not shown). The corresponding sound carrier signal, i.e. the comparatively narrow frequency band, is developed across capacitor 41 which may be the input capacitance of the sound I.F. amplifier. To obtain the band-pass characteristics inductors 13, 23 and 33, 43 may be inductively coupled though this is not essential and in the preferred embodiment inductive coupling is not used. Resistor 40 serves as a neutralizing component to reduce the sharpness of the narrow frequency band.

Title: Enzymatic isomerisation of glucosesyrups in the presence of
IPC: C12N9/92
Filed: 1970-04-07
Abstract: A glucose-isomerising enzyme is added to a glucose-contg. liquid and the liquid is subjected to isomerisation conditions. During isomerisation a small amount of a water-soluble salt of sulphurous acid is present in a quantity which is sufficient to reduce visibly the formation of colour produced in the absence of salt. The quantity of salt is pref. sufficient to produce 0.02-0.3% SO2 in the liquid. Pref. salt is Mg sulphite or -bisulphite. The pref. micro-organisms used to produce the enzyme are Streptomyces ATCC 21175 and 21176. Pref. pH of the liquid during isomerisation is 6.5-7.5. Cell material containing the enzyme is used for isomerisation. This contains foreign matter which produces discolouration of the final product. The salts included reduce the colour and have a protecting effect on the glucose-isomerising enzyme, esp. at higher temps. so that smaller quantities of enzyme are necessary to give the same yield of fructose. The isomerised glucose syrup is used for the sweetening of sauces, tinned fruits, confectionery etc.

Title: Joining air permeable objects using adhesive - setting adhesive by blowing pressurised hot air through objects whilst pressing them together
IPC: C09J5/00
Filed: 1981-11-24
Abstract: The arrangement is for joining two objects in a gas-permeable material, e.g. a chipboard or hardboard panel to a wooden batten, by adhesive applied (in liq. form) to at least one of the surfaces to be joined and pressure applied to hold these surfaces together. The adhesive is set by feeding pressurised gas, pref. air, by means of a blower unit through at least one of the objects from the side opposite to the surface to be joined. This gas may enter that side at a temp. of 200-240 deg.C, pref. at 210-230 deg., and at a pressure of 125-225 kPa, pref. 150-200 kPa. The arrangement ensures rapid heat transfer to the adhesive and avoids unnecessary heating of areas outside the join. It is, therefore, partic. suitable to producing localised, and possibly preliminary, joins and minimises energy consumption.

Title: Method and device for placing or removing a line (pipe) in or from the ground
IPC: F16L1/06
Filed: 1992-11-12
Abstract: The invention relates to a device for introducing or removing a line in or from the ground at a desired sharp insertion angle, the line being driven in its longitudinal direction by means of a line displacer which is kept at the desired angle with respect to the ground, so that the line enters or leaves the ground at the desired sharp insertion angle. In the known method, the line displacer used comprises a ground frame which is placed on the ground and in which an auxiliary frame is pivotably mounted, in which auxiliary frame the drive wheels are rotatably arranged. To ensure that the auxiliary frame is fixed strongly enough, and to prevent it from undesirably coming loose during work, which would cause it to suddenly swing around together with the pipe accommodated therein, with the risk of injury to people working in the area, and to prevent the ground frame from moving with the auxiliary frame during the line- displacement work, which interferes with setting the required insertion angle of the line, the characteristic features of claim 1 are employed, in that the line displacer comprises a frame in which drive wheels are mounted in such a manner that they can rotate in a fixed position, and that this frame, with the aid of a motor vehicle with a jib arm is set at the desired angle with respect to the ground and is held at this angle while the line is being introduced into or removed from the ground.

Patent PT-71099-A (PT)
IPC: C21C5/32
Filed: 1980-04-15
Abstract: A process for refining a metal bath in a converter by oxygen blowing, particularly a molten metal liquid bath containing cold, solid substances, notably of scrap. Oxygen is distributed over the surface of the bath, so that there will be an after-combustion of CO released in the course of decarbonization. The thickness and consistency of a slag layer formed over the bath is actively regulated by injecting a rising inert gas through the bottom of the bath. The flow of rising gas may be regulated depending upon the oxygen content in the fumes of the converter, or upon the intensity of emission through the top of an oxygen blowing lance.
