Title: Continuous Fermentative Process for the Production of Ethyl Alcohol
IPC: C12N1/16
Filed: 1979-05-18
Abstract: In a continuous fermentation of sugar-containing mash to ethyl alcohol using a yeast, the activity of the yeast is maintained by (a) maintaining the fermenting mash containing a flocculating yeast in a state of motion in a fermentation stage; (b) continuously separating the yeast from the, at least partially, fermented mash in a sedimentation stage; (c) dividing the yeast into a recycle yeast and a yeast crop; and (d) recycling the recycle yeast in a homogenized state to the fermentation stage. No fermentation stage contains more than 150% of the amount of yeast required to ferment the mash in a specified residence time. The alcohol content of the resultant solution is thus raised without the introduction of undesirable bacteria into the high nutrient and low alcohol mash.

Patent GB-2072686-A (GB)
Title: A process for the preparation of particle board
IPC: B27N3/02
Filed: 1980-12-15
Abstract: The use of polyisocyanates as binders in the preparation of particle boards is subject to the drawback that the boards exhibit a tendency to adhere to the face of the platens used in their formation. This problem is minimized by incorporating minor amounts of a mixture of certain mono- and di- (saturated or unsaturated aliphatic) acid phosphates or the corresponding pyrophosphates, into the polyisocyanate to be used as binder. The polyisocyanates and the acid phosphates and or pyrophosphates, are applied to the particles separately, or after preblending one with the other. Whether the components are applied separately or in combination one with the other, they can each be applied either neat or in the form of an emulsion or emulsions.

Title: Signal pick-up circuit arrangements
IPC: H04N5/341
Filed: 1981-02-17
Abstract: In a signal pick-up circuit arrangement comprising a solid state image pick-up device including charge transfer elements - eg CCD's - for producing elemental output charges corresponding to an image, wherein during each elemental output interval ( tau B), there is produced in sequence a reference level portion (TP) and a signal portion (TS) which is derived by charging or discharging a capacitance in response to the output charge, both the reference level portion and the signal portion may be contaminated with noise (N). The noise is therefore removed by deriving the difference between the reference level portion and the signal portion. The difference is produced by a differential amplifier (16), either fed with the signal both direct, and via a delay (15) and followed by a sample and hold circuit (10), or by sample and hold circuits, sampling and holding the reference level portion and signal portion for simultaneous comparison. <IMAGE>

Patent GB-2086657-A (GB)
Title: Locking device
IPC: H01H3/30
Filed: 1981-10-28
Abstract: In a locking device for a member 1 which is subjected to an operating force P1, in particular a switching element for high and low tension switching devices, the member 1 cooperates with an adaptor 2 and is retained in the locked position by a spring biased retaining ring 7 which forces ball bearings 4, arranged in a recess 3 on the member, against a surface 9 on the adaptor which is inclined in the direction of the operating force P1. The member 1 is formed with a back surface 16, associated with each ball bearing 4, which lies opposite the inclined surface 9 on the adaptor when the device is in the locked position, and forms an angle with said inclined surface whereby the ball bearings being subjected to the operating force on the member are urged radially outwards against the force exerted thereon by the spring biased retaining ring 7. Thus, when the operating force exceeds a certain value, determined by the pre-loading of the spring bias, the restraining force applied by the retaining ring 7 is overcome and the ball bearings are moved radially outwards, releasing the member 1. <IMAGE>

Title: Color Communication and Matching
IPC: G01J3/52
Filed: 1982-02-17
Abstract: A method for communicating color information and formulating colorants to match a given color wherein a given color definition system defining a color when viewed in a specific light defines input color information. A set of differently colored discs may be additively mixed on being spun and blended according to the Maxwell disc principle. Formulation includes computing those combinations and subcombinations of the set which give the same values within the definition system as the input color. The combinations, weighted according to the proportions of each disc showing in each combination, are averaged to determine a composite combination which, when used to generate a color, will render one which minimizes metamerism when matched with dyes. The composite combination converted directly into spectral reflectances provides input to a standard color matching system. A color is matched by combination of a plurality of dyes on file in the matching system, data on each being included in the system, to provide a matching sample. This can be corrected if necessary. <IMAGE>
