Abstract: ABSTRACT         A method of curing a wet catalyst-curable resin on a substrate in which the substrate is passed through a treating zone provided by a sealed vapor-curing chamber connected to sealed entrance and exit ante chambers at respective ends.  The ante chambers are each separated from the vapor-curing chamber by a wall provided with a passage having height-adjustable means to limit passage of gas.          The substrate is passed in turn through the entrance chamber where the boundary layer of air is substantially replaced by inert gas, through the entrance chamber into the vapor-curing chamber where it is exposed to the catalyst vapor, and then through the exit chamber where the curing vapor is removed.  When a web provides the substrate, a jet of curing vapor is impinged on the web surface as it enters the vapor-curing chamber at an angle and at a velocity effective substantially to remove the barrier layer of gas and permeate the coating.  In starting up the entrance and exit chambers and vapor-curing chamber are purged with inert gas thereby to remove air and on termination of the curing operations the vapor-curing chamber is purged with inert gas to remove curing vapor.  Apparatus is disclosed for carrying out the method, featuring height-adjustable doors between the vapor-curing chamber and the entrance and exit chambers.  Other features are labyrinth seals and turning vanes adjacent to the passage from one chamber to the other to minimize escape of gas.

Abstract: Abstract When making wood chips by means of a transportable chopping apparatus, the power of a machine may be in-sufficient for continuous chopping of a wood load positioned on a feeding means. Thus, the chopping operation must be intermittently stopped by manual control or automatically in order to reset the sufficient number of revolutions. Otherwise the number of revolutions will fall below a critical value, a chopper may be clogged and a machine indeed stopped. The knives of a chopper usually have a powerful self-feed, in other words, while chiiping the wood said knives also pull a log in the feeding direction. Thus, mere stopping of the feeding means is not always enough to stop the chopping but, under the pulling action of said knives, a piece of wood moves even through a stopped feeding means. An object of the present invention is a feed breaking method in a transportable chopping apparatus, the main principle of said method being to automatically effect a short, impulse-like reverse run cycle for a feeding means in conjunction with stopping of the feed. During this cycle a piece of wood releases itself off the grip of the chopper knives, whereby the chopping is interrupted.

Abstract: Abstract of the Disclosure This invention relates to a composition for developing latent electrostatic images by liquid development and a method of transferring the developed image to a carrier sheet over a gap.  The gap is formed by dielectric spacing particles disseminated through a dielectric carrier liquid, through which toner particles are also disseminated. The toner particles and the spacing particles bear the same surface charge so as to repel each other while in the de-veloping liquid.  Apparatus is provided, for use of the novel developing composition, which includes a metering means adapted to remove excess liquid from the surface of a developed image.  In order to induce the spacing particles to migrate toward the photoconductor, the metering means is biased to a potential greater than that of the non-image areas. This enables the spacing particles, which have a higher dielectric constant than the carrier liquid, to migrate toward the photoconductor.  The toner particles, however, will be attracted to the metering means from the background areas so as to maintain these clear of toner particles.  The method contemplates the steps of biasing the metering means with a potential of opposite polarity to the polarity of the toner particles and yet permitting the spacing particles to remain on the photoconductor to perform their spacing function at the gap transfer station.

Abstract: ABSTRACT         An appartus for coin testing including an improved inductive sensing arrangement.  A coin to be tested is passed through an electromagnetic field produced by an inductor which is part of a resistor-inductor type relaxation oscillator operating at a frequency in the range of approximatley 100 kHz to 1 MHz.  The resulting shift in frequency of the relaxation oscillator forms the basis for testing the coin.  The resistor-inductor relaxation oscillator has a linear frequency response with respect to changes in the effective inductance in the oscillator over a range of inductance suitable for testing coins and produces an output signal which is digital in nature and requires no amplitude discrimination or shaping to be suitable for counting.

Abstract: ABSTRACT      Bacteria of the genus Rhizobium nodulate legumes and are responsible for nitrogen fixation.  The energetics of this process are improved if hydrogen uptake ability (Hup) is imparted to the bacteria to "recycle" some of the hydrogen lost during the nitrogen fixation.  Such Hup is observed in a naturally occurring strain of Rhizobium leguminosarum but it was not known how to transfer it to other strains.  The present invention provides recombinant plasmids pIJ1008 and pIJ1007 which enable it to be transferred. These plasmids are formed from a transmissible plasmid, synthesised to include a drug-resistance marker, and a plasmid of the naturally occurring strain.  Cultures containing the plasmids have been deposited in a culture collection and can he used, after appropriate further crosses as described, to impart Hup to other strains of Rhizobium.  In addition, cultures containing the starting trans-missible plasmids (pVW5JI and pVW3JI) have been deposited and can be used to prepare strains of Rhizobium containing the same or similar recombinant plasmids.  Plant growth analysis in laboratory tests demonstrate that rhizobial strains containing these recombinant nodulation plasmids which confer Hup+ ability are superior to the corresponding Rhizobium field isolates in terms of overall plant growth dependent on symbiotic nitrogen fixation.
