Title: Improvements in manufacture of knitted goods
IPC: D06C5/00
Filed: 1941-01-14
Abstract: 540,856. Preserving shape of knitted goods. FRANKFURTHER, P. Jan. 14, 1941, No. 854/40. [Class 15 (ii)] The resistance of knitted goods to loss of shape during wear or washing is improved by treating the goods in finished or unfinished condition with a solution in a volatile solvent of a colourless, water-insoluble organic colloid in such manner that after evaporation of the solvent the elasticity of the material is reduced to some extent, but not wholly eliminated, and the original soft feel and porosity of the material is not materially affected. After evaporation of the solvent, the treated material is slightly moistened with a solvent for the colloid. The process is applicable to the treatment of stockings including those of artificial silk, jerseys, pullovers, underwear, gloves, or shawls, and particularly to stockings and other articles which have been shaped on a former and subjected to heat and pressure. The organic colloid may be a natural or synthetic resin, e.g. polyvinyl acetate, or a cellulose derivative, e.g. cellulose acetate. In the case of washable goods, the colloid although water insoluble should be capable of absorbing water. The treating liquid may contain a water-insoluble softening agent such as dibutyl phthalate. The quantity and concentration of the colloid applied to the knitted goods may be adjusted to allow for the small amount of colloid which will be removed mechanically during the first washing. In this case, a proportion of a watersoluble softening agent, e.g. triacetin may be added to the treating liquid to counteract the stiffening effect of the excess of colloid over that ultimately required. The effect of the final moistening operation with a solvent for the colloid is to improve the adhesion of the colloid to the knitted material and so reduce the tendency for the dressing to be removed during washing, and the effect is enhanced if the moistened material is subjected to heat and pressure. Instead of treating the whole of each article, only those parts which are liable to lose their shape or become distorted may be treated. If it is desired to eliminate completely the elasticity at certain parts, the concentration of the solution applied at these parts may be suitably increased. The solution may be applied by impregnation, spraying, brushing, or printing. Local treatment may be effected by use of stencils. In an example, the treating solution comprises polyvinyl acetate, toluene, xylene, tetrachlorethane, alcohol, amyl acetate. dibutyl phthalate, and triacetin. The proportion of polyvinyl acetate may be 1-3 per cent for impregnation, 2-5 per cent for brushing, or 5-7 per cent for spraying. After evaporation of the solvent, the treated stockings &c. are lightly sprayed with a solvent such as toluene or alcohol and, if desired, heated to 80-100‹C. and pressed.

Title: Television signal scrambling
Inventor: HARADA KIMIHITO
IPC: H04N7/167
Filed: 1990-02-16
Abstract: In a known method of scrambling a television signal by altering its amplitude during horizontal and vertical banking periods and providing as part of an accompanying audio signal a key signal which corresponds to the horizontal blanking periods and indicates the amplitude variation, it is possible to use the interruption of the key signal during the vertical blanking period VBI to restore sync information. Therefore a pseudo-key signal is provided during VBI to conceal the latter, and the audio signal includes further data as to the position of VBI. Such data may occur between two key pulses for example, and thus be detected by its time of occurrence, (Fig.10).

Title: Ultrasonic measuring apparatus including a damped transducer probe
Inventor: KURAMOCHI MITSUGU
IPC: G10K11/00
Filed: 1990-02-22
Abstract: A metallic casing (1) contains a low-frequency resin damper (4); to its front is fitted a transducer (3) and there is a connection (5) for an ultrasonic measuring apparatus which supplies electrical pulses to the transducer; the resultant high-damping probe is useful for measurement of thickness, voids and compressive strength of concrete; the damper absorbs unnecessary low frequency vibrations of the transducer so that the transmission and received waves are clearly separated. 
<??>One or more such probes can be connected to a signal conversion (eg a fast Fourier transform) means, signal processing means (a low-pass filter) and a second signal converting means (an inverse fast Fourier transform), to obtain the signal waveform of the shear wave component of the reflected wave, for measurement of the thickness. Alternatively a probe for both transmission and reception is connected to a variable-frequency transmitting means and to display means for the reflected wave; a frequency appropriate for concrete being tested can thus be transmitted by the probe; the wave will not oscillate for long and superposition of the two waves is preventable. Equations and graphs for measurement methods are disclosed.

Title: Method for determining that pairs of cells in a mobile radio system are completely measured
Inventor: GUNMAR KRISTER
IPC: H04W16/18
Filed: 1990-09-10
Abstract: In cell planning for a cellular mobile radio system, there can be some doubt as to whether the same channel can or cannot be used in certain cell pairs, termed "critical cell pairs". Field strengths around individual cells are recorded to determine interference (I) and coverage (T) areas of the cell and in order to determine that pairs of cells can be considered to have been completely measured, the region of intersection of the first cell interference area (I1) and the second cell coverage area (T2) is determined and compared with the second cell coverage area to form a first quotient, the region of intersection of the second cell interference area (I2) and the first cell coverage area (T1) is determined and compared with the first cell coverage area to form a second quotient, and the first and second quotients are compared with the predetermined minimum acceptable quotient value, which may be 0.9 (i.e. minimum 90% overlap between intersection area and related coverage area).
