Patent GB-953013-A (GB)
Title: Improvements in or relating to the production of sparkling wines and drawing-off apparatus therefor
IPC: C12G1/06
Filed: 1961-06-22
Abstract: Sparkling wines are produced by secondary fermentation of a basic still wine by the addition of yeast and, if necessary, sugar or grape juice, the carbonic acid evolved during the secondary fermentation is removed by suction and stored under pressure until the secondary fermentation is complete and until the secondary still wine so produced has been treated in a usual manner, e.g. filtered, clarified, cooled and, if necessary, a dosage liquor such as cane sugar added, whereupon the stored carbonic acid is re-blended under pressure with the secondary wine to form sparkling wine.  The sugar content of the basic still wine is adjusted such that the carbonic acid which is released suffices to saturate the quantity of secondary still wine subsequently produced with the desired pressure and at the desired temperature, thus 100,000 l basic wine containing 25-30 g of sugar per litre will give off sufficient carbonic acid during the secondary fermentation for a subsequent re-saturation at a pressure of from 4 to 5 atmospheres at 0 DEG C.  The carbonic acid can be conveyed through a purifying bath before being re-incorporated in the secondary fermented wine.  The re-blending may be effected by pumping the secondary fermented wine into the carbonic acid storage tank, or in an intermediate cooling tank; in this latter case the carbonic acid storage tank need not be of sufficient volume to accommo-date the wine.  The sparkling wine produced may be delivered to a filling system by a drawing-off apparatus (see Division F1).ALSO:Sparkling wines are produced by secondary fermentation of a basic still wine by the addition of yeast and, if necessary, sugar or grape juice, the carbonic acid evolved during the secondary fermentation is removed by suction and stored under pressure until the secondary fermentation is complete and until the secondary still wine so produced has been treated in a usual manner, e.g. filtered, clarified, cooled and, if necessary, a dosage liquor such as cane sugar added, whereupon the stored carbonic acid is re-blended under pressure with the secondary wine to form sparkling wine.

Abstract: 205,274. Kendall & Gent (1920), Ltd., and Ingham, J. R. Aug. 19, 1922. Milling-machines.-A milling-machine of the planer type is adapted for copying by providing a vertically slidable cross-slide and controlling the vertical movements by means of a roller and a templet. The reciprocating table d carries a templet c acting on a roller e mounted in bearings on a bracket f sliding on a vertical support b which also forms one of the guides for the cross-slide a. Two templets may be used, one at each side of the table. The distance between the guide and bracket is adjusted for determining the depth of cut by a screwed spindle g, secured to the bracket and attached to the slide by means of a nut h which may be rotated by a hand operated shaft i and bevel gears j. The slide and bracket are lifted to clear the templet on reversal of the table by a worm-nut p acting on an axiallymovable screwed-spindle o contacting with a lug q on the bracket. The pressure of the tool may be increased by a balance weight k and chain k<1> which passes over pulleys k<2>, k<5> the usual weight n being removed. To relieve the pressure on the templet, the chain k<1> is attached to the pulley k<2> and a chain m secured to a pulley m<1> on the same shaft supports the slide a. To relieve pressure on the templet by hand, for instance when a sharp incline is encountered, the bracket is raised by a handle S and pinion r engaging the threads of the spindle o. To ensure a parallel motion of the slide, pinions u<2> on the slide engage racks v on a cross-stay w of the machine, or the pinions and racks may be interchanged. The table is supported under the templet by a, wedgesupported roller or a wedge x which is adjustable to take up wear.

Title: Improvements in or relating to wrapping machines
IPC: B65B61/28
Filed: 1924-09-29
Abstract: 244,846. Rose, W., and Rose Bros. (Gainsborough), Ltd. Sept. 29, 1924. Packeting by wrapping-up. - Relates to apparatus for making the final folds in the projecting ends of wrappers placed round blocks of confectionery &c. held in moulds in an intermittently rotating wheel and for transferring the wrapped blocks to a delivery channel, gum being applied to the last-folded flaps of the wrappers. The blocks to be treated are brought into the position X, Fig 1, by an intermittently rotating vertical wheel 5, each block being already completely wrapped except as regards the lateral flaps adjoining the top face of the block and also adjoining that face which is remote from the plunger 2. When the block is discharged from the wheel 5 by movement of the plunger 2 the flaps remote from the plunger are folded over the ends of the block by plates 19, 20, Figs. 1 and 4, carried by a lever 18. The block comes to rest on a platform 10 mounted on a spring-pressed lever 12 bearing against a stop 24, and the lever 18 is then raised slightly so that the upper faces of the folders 19, 20 press the triangular top flaps of the wrapper against fixed members 16 not shown in Fig. 1. The block is then gripped between a plate 29 and pivoted nippers 34 carried by a swinging arm 27, pivoted at 28, the nippers 34 parsing through slots in the plunger 2. The platform 10 is slightly lowered and the arm 27 moves so as to carry the block opposite a delivery channel 43, Fig. 6, during this movement the triangular top flaps a of the wrapper receive adhesive from a pair of wheels 44 against which they are pressed by projections 50 on a member 49 secured to the adhesive-tank 45. After the nippers 34 have been moved slightly to release the block, a plunger 62 mounted on a slide 52 presses the lock between a pair of rollers 71, thus folding over the flaps a and completing the folding operations. The rollers 71 carry endless travelling belts 73 constituting the side walls of the delivery shoot 43.

Title: Apparatus for measuring the circular dichroism of optically active substances
IPC: G01N21/19
Filed: 1961-06-23
Abstract: 979, 712. Photo-electric measurement of circular dichroism. ROUSSEL-UCLAF. June 23, 1961 [June 29, 1960], No. 22903/61. Heading G1A. [Also in Divisions G2, H3 and H4] Apparatus for measuring circular dichroism of a substance comprises means for producing a beam of light oscillating between left and right circular polarisation and photo-electric means recording the difference of absorption of light by the substance for left and right circularly polarised light as a function of the wavelength thereof. Visible and ultraviolet light from an arc 1 is directed through a variable quartz or grating monochromator 3 and a silica collimator 7 to a Rochon prism 8 which splits the light beam into ordinary and extraordinary components. The latter'is obstructed by a diaphragm 9, but the former passes to an electro-optical modulator 10 comprising a crystal of ammonium dihydrogen phosphate subjected to an electric field in the direction of propagation. The field alternates with the result that the light beam is alternately left and right circularly polarised and passes through the specimen 12 to a photomultiplier 13. The photomultiplier output has A.C. and D.C. components V A  and V c  respectively which are separated; V A  being applied to a synchronous rectifier fed from the same source as modulator 10 to give a D.C. output V d  and the ratio V d /V c  which is proportional to the circular dichroism is derived by a recording self-balancing potentiometer. The modulator may be replaced by a Fresnel prism, and Rochon prism 8 is then continuously rotated or a Faraday cell oscillates the plane of polarisation, Figs. 3 and 4 (not shown). In another modification, Fig. 5, (not shown) a Faraday cell and a Rochon prism at 45 degrees to prism 8 are inserted between prism 8 and diaphragm 9. The A.C. output of photomultiplier 13 is fed to the Faraday cell through a high gain loop, to reduce the A.C. substantially to zero. The Faraday current then indicates the circular dichroism. A variable transformer 14 coupled to the wavelength drive of monochromator 3 supplies modulator 10 so that the latter provides a circularly polarised beam at all wavelengths. Linearity is improved by applying the D.C. output of the photomultiplier to keep the amount of light passing through slit 5 substantially constant.
