Abstract: This invention relates to a combination silk screen and heat press apparatus, which is configured such that silk screening and heat pressing operations may be performed on an article, such as a garment, using the same apparatus without the need to remove or reposition the article.

Abstract: This invention relates to a manually operated silk screen device that allows multi-colored graphics to be produced whose color is consistent and properly aligned on articles such as garments. The consistency in color is achieved by controlling the pressure and angle of the silk screen squeegee by a pneumatic or hydraulic mechanism. Screen frames are securely mounted and aligned within the device by a pin registration system.

Abstract: One embodiment of this invention discloses a silk screening device which includes an integrated quartz flash unit. The invention improves upon prior art systems and relates to a system whereby both a silk screen squeegee unit and a quartz flash unit are slidably mounted on a common set of rails, in order to allow each to be easily placed and removed from the silk screening platform.

Abstract: The invention relates to a cleaning composition suitable for manually cleaning substrates. The composition comprises at least two immiscible liquid phases having one liquid-liquid interface with an interfacial tension of more than 5 mN/m, the difference in density between the two liquid phases being not more than 0.2 g/cc. After agitation, the composition is applied to the substrate to be cleaned, and subsequently friction is applied to the substrate. The composition provides for the required stability after agitation, and gives good detergency, particularly as regards particulate soil.

Abstract: The invention relates to a cleaning composition comprising an immiscible liquid system having at least one liquid—liquid interface with an interfacial tension greater than 5 mN/m. The less polar solvent in the system has a carbon chain length of at least 4, preferably greater than 6, or is a silicone with more than 3 SiO units. Typical examples of suitable less polar solvents are hydrocarbons, fluoroethers, polydimethylsiloxanes and fatty acid methyl esters. The more polar liquid in the system is preferably water. The composition is particularly suitable for cleaning soiled fabric, especially to remove particulate soil therefrom.

Abstract: The present invention relates to a washing machine in which a composition is used comprising at least one liquid-liquid interface, with an interfacial tension of at least 5 mN/m. The washing machine comprises a heatable wash drum, means for storing dispensing and mixing the liquids, means for introducing the liquids into the drum, and means for filtering, separating, distilling and condensing the wash liquor and vapours and recovering the solvents. Use of the machine enables discharge of waste water with only low levels of solvent, and facilities recovering of the solvents.

Abstract: A process of cleaning a substrate, the process comprising the steps of contacting a substrate with a composition comprising at least two liquids mutually presenting a liquid-liquid interface with an interfacial tension of at least 5 mN/m and agitating the substrate and/or composition whilst they are in mutual contact, wherein the composition and/or the substrate are also subjected to ultrasound before and/or during the agitation step.

Abstract: The preparation of a mixture comprising branched fatty acids and oligomerised fatty acids comprises contacting a source of unsaturated fatty acids or their derivatives with an ionic liquid.

Abstract: The invention relates to a process for the branching of fatty acids or derivatives thereof. More in particular, the invention provides a method for branching saturated fatty acids. This is achieved by contacting a source comprising fatty acids or derivatives thereof, with an ionic liquid. The invention also relates to the mixture of branched fatty acids so obtained.

Abstract: The preparation of a mixture comprising branched fatty acids and oligomerised fatty acids comprises contacting a source of unsaturated fatty acids or their derivatives with an ionic liquid.

Abstract: It was found that the conversion (by isomerisation or branching) of unsaturated fatty acids into branched fatty acids can be catalysed by materials having a microporous structure. Such a process gives high conversion rates and a high selectivity towards branched fatty acids, whilst a low amount of undesired by-products is obtained. Zeolites are preferred materials for catalysing said reaction.

Abstract: A selection system in a space diversity system of a mobile receiver combines the ultra high frequency signals after they have been frequency shifted to an intermediate frequency. The system combines the intermediate frequency signals depending on the ratio of the magnitudes of these signals. If the ratio of the magnitude of the received signals is equal to or greater than a preset magnitude level, for example, 5 db, a control unit selects only the received signal having the largest magnitude. Otherwise, the control unit linearly combines both received signals Specifically, if the absolute value of the difference in received phase signals is less than 90.degree., the output of a phase detector causes the control unit to pass both received signals to a summer that linearly combines them prior to demodulation. Otherwise, the control unit inverts the phase of one of the received signals prior to passing both received signals to the summer.

Abstract: A receiver suitable for use in a radio-telephone system for recovering data from encoded, quadrature-modulated communication signals employs a feedback arrangement for suppressing cross-talk between the receiver's in-phase and quadrature channels to improve data recovery rates during decoding. The receiver converts in-coming analog communication signals into in-phase and quadrature digital signals, which may have cross-talk components. The receiver has an attenuator for subtracting feedback signals from the in-phase and quadrature digital signals to produce cross-talk-attenuated in-phase and quadrature digital signals, a decoder for decoding the cross-talk-attenuated in-phase and quadrature digital signals to generate first and second data output signals, and the above-mentioned feedback arrangement, which preferably employs a recoder and cross-correlation techniques, for generating the feedback signals.
