Abstract:
A smoking article comprises a first part and a second part movable relative to the first part. A control mechanism comprises a first control surface on one of the first part or second part; and a second control surface on the other of the first and second parts. The second control surface is configured to engage with the first control surface to control relative rotation between the first part and second part.
Abstract:
A piezoelectric laminate comprises a piezoelectric layer and an insulating substrate layer rigidly bonded thereto. During poling, conditions are established under which a poling potential is established at the boundary of the layers which insures that a substantial part of the poling voltage is dropped across the piezoelectric layer. The poling voltage is maintained for a period greater than the time constant under the poling conditions of the material to which the poling voltage is applied. In one embodiment, the poling conditions are achieved by substantially enhancing the conductivity of the substrate layer relative to that of the piezoelectric layer. In a second embodiment, an intermediate bond layer is selectively switched from a non-conductive to a conductive state in response to a selected stimulus so as to form an electrode for facilitating the application of a poling field directly across the piezoelectric layer.
Abstract:
An improved droplet printing apparatus of the type wherein a succession of ink droplets directed at regular intervals along the same flight path may be individually charged to one of a plurality of charge levels by application of a voltage waveform of constant period to groups of drops. Each charged drop is deflected from the common flight path by passage through an electric field, to an extent dependent on the charge carried so that during relative motion between the apparatus and a surface to be printed ink drops may be deposited on the surface in successive rows extending transversely to the direction of relative motion; all ink drops not being required for deposition being directed into a drop intercepting means. The improvement comprises the provision of means for introducing a delay between adjacent voltage waveforms and means for directing all drops formed during such delay into the drop intercepting means.

Abstract:
Methods of treating dehulled or hull-less oat, i.e. oat groats, to produce oat pearlings, oat flour and oat bran products are described. Oat groats are abrasion milled to remove up to 15% by weight and produce pearled oat groats and pearlings. The pearlings are extracted sequentially with aqueous ethanol and hexane to produce an anti-irritant and a light oat oil, or with hexane to produce a dark oat oil and lipase. The pearled oat groats are steeped in an aqueous medium for up to 4 hours and then macerated to produce an enriched oat bran, from which an enriched beta glucan may be extracted; a refined oat flour, from which oat starch and oat protein may be extracted; and a pearled oat groat extract from which further products, such as an oat anti-irritant can be recovered.
Abstract:
A process for treating cereal grains and particularly oats, to separate the endosperm from the remainder of the kernel without dry milling. The grains are soaked in an aqueous medium having a pH of 3.0-7.0 at a temperature in the range 40.degree.-70.degree. C. for sufficient time to absorb at least an equal weight of the liquid medium. The conditions are such that the endosperm portion of the grain liquefies, as opposed to softens. The grain may be crushed in a variety of ways to split the husk and release the liquid endosperm contents which are then dispersed in water. The endosperm solids can be recovered from dispersion, following a screening step to separate the husks by drying to yield a substantially white, lower fiber whole endosperm flour product. Alternatively, the dispersion may be sedimented and/or centrifuged to produce a wet solids fraction and a soluble fraction, each of which can be subsequently recovered in dry form.
Abstract:
Process for the production of drop streams by modulating a liquid jet issuing from a nozzle, characterized in that the jet modulation comprises a wave having the fundamental frequency of drop formation, together with a second wave whose frequency is twice that of the fundamental wave.This simultaneous use of the two waves controls the shape of the devices for the production of such drop streams, and the use of such drop streams in droplet printing, in crop spraying and the production of spray dried products.

Abstract:
A process for commercial extraction of saponins from quinoa, and optionally for the formation of corresponding sapogenins. The saponin extraction process comprises contacting a saponin-containing part of a quinoa plant with an aqueous alcohol solution containing an alcohol selected from the group consisting of methanol and ethanol to form a saponin-containing solution and an extracted solid residue, removing the alcohol from the saponin-containing solution to leave a saponin-containing aqueous solution, and evaporating water from the saponin-containing aqueous solution to produce a saponin-containing product. The conversion to sapogenins involves obtaining a solution of saponins in an aqueous alcohol, adding a strong acid to the solution to hydrolyze the saponins to form corresponding sapogenins that precipitates out of the solution as a precipitate, recovering the precipitate, and decolorizing the precipitate by forming a slurry of the precipitate with a solution of an aqueous base to form a decolorized sapogenin product.
