Patent EP-0360371-A2 (EP)
Inventor: HORNER TERRY A
IPC: B01F5/06
Filed: 1989-03-08
Abstract: The invention relates to motionless mixers and baffles thereof and includes a baffle having a pair of substantially symmetric opposing major surfaces generally helically twisted along a central longitudinal axis of the baffle and a first pair of substantially planar surfaces connecting the pair of major surfaces at one end of the baffle, one of the first pair of planar surface extending both substantially transversely and substantially parallel to the central longitudinal axis. The intersection of the first planar surface and one of the major surfaces forms an edge at the one end of the baffle. Such geometry enables a plurality of the baffles to be formed as a single insert unit by conventional injection molding techniques using only a pair of mold halves. The major surfaces are concave in cross-section normal to the longitudinal axis to form with a housing a pair of passages of generally ovoid (or elliptical) cross-section.

Abstract: The invention comprises an automatic technique for assigning addresses to modular units connected to a computer system bus. In its broadest aspects, the in­vention comprises the method of initially generating a unique address in a controller module attached to the expansion bus and thereafter transferring the unique address to the next expansion module. The next expan­sion module receives the unique address, is identified by the unique address, and generates a new unique address using the received unique address. Thereafter the expansion module transfers the new unique address to the next expansion module which likewise uses the received address to identify itself. The steps are repeated until each expansion module has received a unique address to identify itself. In the preferred embodiment a Read Only Memory (ROM) is used to receive the unique address and to generate a new address for transferring to the next module. No particular tech­nical skill is required in order to configure this sys­tem and the modules will be automatically addressed irrespective of their place along the expansion bus. The invention eliminates the need for an end user to uniquely jumper id pins at each module to provide each module a unique address.

Abstract: This invention relates to a hydrosilation process involving the reaction of a compound containing silicon-bonded hydrogen with a compound containing aliphatic unsaturation. 
     Platinum complexes are known to be useful as catalysts in processes for accelerating the thermally-activated addition reaction between compounds containing silicon-bonded hydrogen and compounds containing aliphatic unsaturation. However, processes for promoting the visible radiation activated addition reaction between these compounds are unknown. Platinum complexes that can be used to initiate ultraviolet radiation activated hydrosilation reactions are also known. However, it is not known whether platinum complexes would be useful for initiating a visible radiation activated hydrosilation reaction. 
     This invention provides a process for the addition of compounds containing silicon-bonded hydrogen to compounds containing aliphatic unsaturation and compositions suitable for said process. The process is activated by visible radiation and is conducted in the presence of a platinum complex having one cyclopentadienyl group that is  eta -bonded to the platinum atom and three aliphatic groups that are  sigma -bonded to the platinum atom and a sensitizer that is capable of absorbing visible light and is capable of transferring energy to said platinum complex such that the hydrosilation reaction is initiated upon exposure to visible light. The invention also provides compositions for use in the aforementioned process.

Abstract: 2.1 In an interface standardised for digital communication exchanges, which allows several subscriber terminals to be connected, internal connections between these subscriber terminals connected to one and the same interface are to be possible, only one useful-data channel being occupied so that at least one further useful-data channel is available for incoming or outgoing connections. 2.2 A channel control unit is connected between the interface of the communication exchange and the bus line coming from it and leading to the subscriber terminals. This control unit contains a program control which, when a connection coming from one of the connected terminals is set up, recognises from the information sent in the signalling channel whether the connection leads to a terminal connected to the same bus line. A switch-over device is then activated which switches the transmitting line to the receiving line whilst the useful-data channel seized is connected through so that only one useful-data channel is occupied in which then a one-way or two-way alternate internal connection exists. 2.3 This method has the result that the interface can still be seized by an outgoing or incoming connection even when an internal connection is already connected through between two subscriber terminals connected to the same interface.

Abstract: The invention relates to apparatus for on-line particle determination in molten metals, wherein a sample of the molten metal is drawn by a vacuum through a calibrated passage (22) in the side-wall of a heat-resistant tube (16) while a current is established through the passage between two electrodes (12,14) on either side thereof. The passage of non-conducting particles through the orifice produces pulses whose magnitude and rate indicate respectively their size and the number of particles per unit volume. The electrodes (12,14) and their leads (30,32) form an interference-receiving antenna so that the wanted test signal, whose signal/noise ratio is inherently low, is subject to interference from neighbouring sources, such as motors, fluorescent lamps and particularly induction furnaces. The invention provides for the production of a cancellation signal to reduce the unwanted interference component in the test signal by means of a cancellation antenna sufficiently close to the detector electrodes to receive substantially the same signal, the antenna either feeding the cancellation signal to a differential amplifier also fed with the wanted signal, or being connected in series with the interference antenna. The cancellation antenna can comprise a loop mounted on the head that supports the two electrodes.

Abstract: A mass biosensor uses an intermediate avidin layer to facilitate binding of a biotinylated antibody to a measurement surface of the biosensor. The avidin layer can be added by the manufacturer of the biosensor, while the biotinylated layer can be added by the user. This two-phase method of chemically modifying the measurement surface significantly reduces the user time required to customize the measurement surface to render it capable of binding selected compounds. An organosilane coupling agent attached to the surface provides sites to which avidin is bound. Avidin acts as a universal receptor of biotinylated compounds with specific binding affinities. Biotinylated antibodies or other biotinylated compounds are added and bind to the immobilized avidin. Surface adsorption is reduced by washing the modified surface with biotin to block potential sites of weak bond formation, electrostatic and hydrophobic interactions.
