Abstract: Epoxide-functionalized polyphenylene ethers, which may be prepared by the reaction of various acid-functional­ized polyphenylene ethers with functionalized epoxides, are useful in the preparation of polyphenylene ether copolymers. These copolymers are, in turn, useful for the compatibiliza­tion of blends of polyphenylene ethers with such other polymers as polyesters and polyamides.

Abstract: A tester of circuit devices is disclosed which uses commercially available component parts but is capable of high performance testing of hierarchical memory cards requiring data pulses of variable pulse widths at high repetition rates. The tester includes two memories connected to respective shift registers which in turn, feed a multiplexer. The memories handle test timing patterns for respective halves of the basic clock test cycle and are interleaved in operation along with the shift registers. Two opposite-phased outputs of the multiplexer are applied through respective programmable delay networks and pulse generators to the set and reset inputs of a trigger circuit. The trigger circuit provides test data to a dedicated input pin of the device under test.

Abstract: In a manual mode of a switch (40) engine speed control is determined by signal (SLP) from a speed lever (52), acting on the engine (10) by way of a governor (32) responsive also to an engine speed feedback signal from a sensor (48). The ratio of a multi-­speed transmission is determined manually by means of a gear-shift lever (16). In an automatic mode a selector switch (42) determined whether the speed lever (52) commands engine speed or ground speed. In the former case the governor (32) acts as in the manual mode and an electronic control unit (30) takes over the transmission ratio selection via a stepping motor (24) and shifts down or up as may be needed to prevent the engine speed drooping or rising outside a permissible band centred on the commanded engine speed. In the automatic, ground speed mode, the speed lever signal (SLP) is treated as a commanded ground speed signal which the control unit (30) compares with actual ground speed, computed from the actual engine speed signal and the current transmission ratio or gear number signalled by an encoder (26). The control unit (30) now determines the signal (ESC) which commands engine speed (instead of SLP) and also selects the appropriate transmission ratio via the stepping motor (24).

Abstract: A charged paraticle energy analyser, such as a microscope or spectrometer, includes a magnetic immersion lens 10 to focus charged particles emitted from an irradiated specimen 5 locatd within the magnetic field of the lens. A collecting aperture 18 defines the area of the irradiated specimen from which charged particles can be brought to a focus in the image plane of the lens but an aperture 21 in this plane selects and defines a much smaller area of the specimen from which the received particles are passed to a suitable energy analysing means 25. The energy analysing means 25 then performs energy analysis of the small selected area of the specimen by imaging the small area with emitted particles of a predetermined energy, or energy scanning the particles emitted from this area, so giving a chemical analysis of the small selected area of the specimen surface.

Abstract: In the case of a device for detecting the spatial orientation of excessively heated points of wheel bearings and/or wheel running treads of rail vehicles, it is suggested that a deflecting device, such as an oscillating mirror 5, that can be varied periodically in its slope, be inserted into the path of the rays from a measuring point to a heat radiation sensor 7. The ray that is deflected when the slope of the deflecting device is changed can in this way also arrive on reflecting surfaces 10 for the purpose of autocollimation, thereby enabling an improvement in measuring precision. Radiation emitted from the detector is periodically reflected back onto the detector to provide a reference signal.

Abstract: Ceramic orthodontic brackets are bonded to teeth with dental adhesive. Each bracket has a silica-­containing layer on the tooth facing base of the bracket. A silanation layer is also applied to the base. The silanation layer is deposited from a solution containing a first silane coupling agent reactive with organic resin in the adhesive and a second silane coupling agent having a non-reactive organic group. Collectively the silanes occupy all of the silanation sites on the silica-containing substrate. By controlling the ratio of reactive and non-reactive silane coupling agents, the bond strength between the substrate and the adhesive can be controlled. A set of ceramic orthodontic brackets can have uniform force of removal by varying the proportions of silane coupling agents on the brackets.

Abstract: Known processes for decaffeinating green coffee using water-containing liquid carbon dioxide operate above the critical pressure of the carbon dioxide. This is considered necessary, as it is feared that aroma components would be coextracted at lower pressures. In contrast, the object of the invention is to provide a more economical decaffeination process without adversely affecting the aroma of the green coffee. This object is achieved by a process for green coffee decaffeination in which the green coffee is adjusted to an increased water content and then selectively extracted with water-containing liquid carbon dioxide at below the critical pressure of the carbon dioxide. This can be carried out particularly economically; surprisingly no aroma loss at all takes place by coextraction of constituents.
