Inventor: SWERTZ MICHAEL DIPL CHEM DR
IPC: G01N33/32
Filed: 1991-10-09
Abstract: Determn. of the stability of an aq. compsn. (I) contg. metal pigment (II), is conducted by homogenising (I) and removing the gases present, then leaving (I) unagitated, without drying or evapn. of volatiles and determining the surface change. Pref. (I) is an aq. coating compsn. an intermediate for this or a component contg. (II) and pref. is dark-coloured. It contains 1.0-25.0 (wt.)% (II) which may be increased before test. (II) pref. is finely-divided Al pigment. (I) is pref. stirred for 1 hr to 5 days. The surface is tested in a film thickness of over 0.5 cm. The compsn. is left at 20-40 deg. C and the test time is 3 hrs to 3 days. The surface change is determined by direct or pref. indirect comparison with the surface of freshly homogenised and degassed (I), pref. by comparing the change in brilliance, hue and/or (II) orientation, esp. using a computer technique. USE/ADVANTAGE - The technique is quick and simple and can be automated. Suitable for testing e.g. water-based metallic paint for cars

Title: Ultrasonic cleaning of articles immersed in cleaning fluid - using piezoelectric transducer excited at high frequency with significant tension only during expansion or compression phase
IPC: B08B3/12
Filed: 1991-10-08
Abstract: The method involves using a source of ultrasound which includes a pair of platelike piezoelectric elements (1, 2) with an electrode (3) between them, screwed (4) together to a vibratory body (5) with a counterweight. (6). The screw (4) also provides an electrical connection to the earthed electrode (7). The piezoelectric elements (1, 2) are deformed by the voltage applied to the electrodes (3, 7) from a high-frequency generator (8). Polarity and waveform are selected so that little or no tension is produced during one or other of the phases of oscillation. ADVANTAGE - Wear and destruction of the ultrasound-reflecting surfaces are reduced greatly by a simple expedient.

Title: Nonwoven fabric - utilises process of heat-treatment of natural pectin content followed by mechanical compression
Inventor: REUSSMANN THOMAS
IPC: D06M15/03
Filed: 1992-12-16
Abstract: Process is for consolidation of textile material, partic. a nonwoven web of natural fibes. By means of heat treatment, the pectin content of the material is softened at between 150 deg.C. and 200 - 230 deg.C. before compression by mechanical means. The temp. for the process is pref. selected to meet the pectin requirement without causing stains or damage to the fibre. This can be selected according to the nature of the fibre. Flax and hemp already contain pectin in the plant, and some remains even after processing. The problems which arise with these fibres in other nonwoven processes may be overcome by the use of the residual pectin. ADVANTAGE - The pectin is found naturally in the stem of may natural fibres. It is bioloigically decomposed, and therefore environmentally friendly. It forms a sound adhesive for the purpose

Title: Digitisation of band-limited analogue signal for hearing aid - using amplifier with adjustable gain controlled by comparator fed from A=D converter, which stores scale unit
Inventor: SCHAUB ARTHUR
IPC: H04R25/00
Filed: 1993-01-26
Abstract: The method involves amplifying an analogue signal in an amplifier with an adjustable gain control. The amplified band limited analogue signal (In) and fed to the digitiser (5). The digital signal (A5) is used as an actual signal (IST) by the comparator (10). The difference signal (delta) between the required signal (SOLL) and the actual signal (IST) is stored in the gain memory (9). The gain of the amplifier (6) is adjusted until the measured (IST) and required (SOLL) signals are equal. The instantaneous digital signal (E71) and the corresponding gain (E72) are stored in the store-scale unit (7). The output signal (A7) is obtained by scaling the digital signal (A5) with the inverse of the gain (G power (-1)). A digital filter is also provided which does not require multiplication units for multiplying the digital signal with filter coefficients. ADVANTAGE - Number of quantisation steps is reduced, giving reduced power consumption while maintaining dynamic range.

Title: Device and method for the wet-wash concentration of solids
Inventor: GILDEMEISTER HANS-H DR ING
IPC: B03B5/32
Filed: 1993-02-20
Abstract: In wet-wash separation of solids according to the their density in a separating device by sink-float separation in a centrifugal zone of a rotating container with a transport device for the discharge of the separated solids, difficulties can arise during the discharge of the floating material which can be caused by unfavourable friction ratios of the floating material relative to the transport device and, for example, extremely low density of the floating material relative to the separating liquid. By the injection of a gas flow according to the invention through nozzles (25) arranged in the container (1) onto the layer (17) of floating material, a force assisting the transport is exerted on this layer (17) of floating material, as a result of which the discharge of floating material is ensured even in the case of floating solids which are otherwise very difficult to transport. <IMAGE>

Abstract: A telecine uses a flying-spot scanner (2) to derive video images from a film and a scan control circuit (4) is used to control the scan of the flying-spot to introduce special effects. Pairs of successive images may be misaligned due to judder and a motion vector estimator (12) is used to detect the amount of misalignment. This produces a shift vector for an image stabilizer (14) to shift one of the images of a pair. The motion vector estimator (12) also receives data from the scan control circuit (4) relating to any special effect in the images and corrects the shift vector in dependence on this. <IMAGE>
